Product advantages

Structural features

This product is divided into two major parts: the cabinet body and the trolley. The cabinet body is made by bending steel plates, spraying plastic and then assembling them with bolts. According to functional features, it can be divided into four parts: the small busbar room, the relay instrument room, the trolley room, the cable room and the busbar room. Each part is separated by grounded metal partitions. The protection grade of the cabinet shell is IP4X. The handcart compartment door is open, with a protection level of IP2X

This switchgear features main circuit schemes such as cable incoming and outgoing lines, overhead incoming and outgoing lines, busbar connection, isolation, voltage transformer, and lightning arrester. The busbar adopts composite insulation. The phases and connection heads are equipped with insulating sleeves made of flame-retardant materials through injection molding. The adjacent cabinets of the main busbar are separated by through-wall sleeves, which can effectively prevent the spread of accidents and at the same time provide auxiliary support for the main busbar. The cable room is equipped with grounding switches, overvoltage protection devices, etc.

The front of the contact box is equipped with a metal valve. The upper and lower valves automatically open when the trolley moves from the open/test position to the working position, and automatically close when the trolley moves in the opposite direction, effectively isolating from high voltage. The interlocks among the main switch, trolley, grounding switch and cabinet door all adopt forced mechanical interlocking methods, meeting the "five-prevention"functional requirements.

The circuit breaker trolley adopts a lead screw drive propulsion mechanism and an overrunning clutch. The lead screw nut propulsion mechanism operates easily, allowing the trolley to move between the test position and the working position. With the self-locking property of the lead screw nut, the trolley can be reliably locked in the working position, preventing accidents caused by the trolley's movement due to the effect of electromagnetic force. The overrunning clutch functions when the trolley moves back to the test position and approaches the working position, automatically disengaging the operating shaft from the lead screw shaft and causing it to idle, which can prevent damage to the propulsion mechanism due to misoperation. Other trolleys adopt lever propulsion mechanisms. The working position of the test is locked by a locating pin.

Cabinet body combination form

Drawer Cabinet (MCC)

The drawer cabinet is composed of drawers, cabinet body frames and related components. All electrical components are fixedly installed inside the drawers. The standard specifications of the drawer unit include 8E/4, 8E/2, 8E, 16E, and 24E(E=25mm). Drawers of the same specification can be conveniently interchanged.

The rated current of the drawer is up to 400A. Each device can be equipped with 9 8E unit drawers, and up to 36 circuits (8E/4) can be combined.

It can be used in motor control circuits and also for power distribution.

Horizontal busbar

The horizontal busbar of the switch cabinet is arranged in the compartment of the switch cabinet. It can be placed behind or on top of the cabinet.

When the horizontal busbar is placed behind the cabinet, it can be arranged in upper and lower layers.

The single-layer horizontal busbar system consists of two busbars for each phase and is suitable for system currents of 2500A and below.

When the system current exceeds 2500A, the horizontal busbars are arranged in double layers, with each busbar group consisting of 4 busbars (with a rated current up to 4000A). The cross-sectional sizes of the two main busbars can be different.

The busbar material is T2 copper, and the specifications are (30mm×10mm,60mm×10mm, 80mm×10mm). Busbars of different cross-sectional dimensions can also be connected. When connecting thehorizontal busbar with the busbar inside the cabinet, no holes need to be drilled.

The horizontal busbar in the cabinet body of the rear outgoing line structure should be placed on the top of the cabinet (the maximum current is 3150A. When it exceeds 3150A, one 8E unit should be reduced, that is, the height occupied by the functional unit of the cabinet body is 1600mm).

Vertical busbar

The vertical busbar is arranged in the vertical busbar room and is used to connect the functional unitswith the earth busbar. The vertical busbar adopts "L" -shaped right-angle copper busbar, which is placed in a specially designed multi-functional board and can be three-phase or four-phase.

After the drawer unit is pulled out, its protection grade can reach lP20.

◆Protective conductor

The protective conductor is used to ensure the equipotential connection of the frame. It consists of horizontal and vertical conductors located inside each cabinet. The horizontal conductor is connected to the cabinet frame and other horizontal conductors, while the vertical conductor is used to connect the protective conductor of the power cable and the grounding wire.

The cross-sectional area of the protective conductor can be made by selecting standard copper busbars of corresponding specifications according to the actual current size requirements.

Smash the small busbar

The control busbar is used to provide power for the entire control loop, as well as working power for some communication devices or fieldbuses.

The control busbar can be installed in a dedicated compartment and laid throughout the system as needed.

Cable Room

A dedicated passage for laying power cables and control cables is located in an independent compartment in front of or behind the cabinet.

The cable room is equipped with dedicated primary and secondary terminal blocks as well as corresponding cable fasteners.

According to the actual size of the cable and the way the cable enters and exits the cabinet, cable exit rings or exit flange plates are installed on the bottom plate or top cover plate.

The size of the cable room can be expanded or compressed according to the corresponding module as per the user's requirements.

Drawer-type functional unit

The drawer contains several functional components of mechanical mechanisms, which ensure that the drawer has positions such as connection/test/separation/removal, and can be locked at different positions respectively with padlocks. At the same time, display, control and human-machine interface components are also integrated on the front panel.

By operating the handle and the large interlock, the drawer can be accurately positioned at the connection, test, separation, removal and other positions. Each position has corresponding markings on the front panel, which is simple and intuitive.

When the circuit breaker is closed, the mechanical interlock device prevents the drawer from moving, ensuring operational safety.

During the operation, it is possible to adjust or inspect the internal condition of the drawer. Therefore, it is necessary to open the drawer panel. The corresponding unlocking tool can be used to open the drawer panel.

Each drawer unit is completely independent, and the drawer cabinets are completely isolated.

Drawer units of the same specification can be flexibly interchanged.

The outgoing line side is directly connected to the fixed outgoing line adapter, and the secondary line is connected by a dedicated secondary connector. (For secondary plug-ins, the maximum number of cores for 8E/4 units is 16, and for 8E/2 units and above, it is 32.)

All kinds of drawer units of various specifications are equipped with corresponding entry and exit guide rails and rollers, which can guide their entry and exit as well as positioning. Rollers can effectively reduce the force required for operation.

The dedicated three-section guide rail not only makes the drawer's entry and exit more flexible, but also effectively ensures that the drawer can be led out of the cabinet frame. Even if the drawer unit does not leave the frame, it can still be inspected or maintained.

Depending on the height of the drawer unit or the magnitude of the current in the same circuit, a pushing mechanism can also be installed on a unit and a drawer.

O Drawer units are particularly suitable for motor control circuits. For distribution type circuits, selection canalso be made based on various functions and actual needs.

Fixed separable functional unit (based on fixed or insertable components)

This type of functional unit retains the advantages of the fixed unit, such as simple structure and convenient operation, while also having the characteristics of clear separation and reliable isolation of the drawer cabinet functional unit. It is applicable to both distribution circuits and motor control circuits.

The plug-in components can be pulled out for maintenance or replacement without cutting off the power supply. The use of such components can ensure that during equipment maintenance, only the components of the corresponding circuit need to be pulled out, without affecting other circuits in the entire power distribution system.

Through the interlock between the operating mechanism and the rotating handle on the panel, it can be ensured that the door cannot be opened when the circuit breaker is closed, enhancing the safety of the equipment.

When the equipment is in operation, if it is necessary to set or spot-check the internal components of the unit, the corresponding unlocking tool can be used to open the panel at this time.

Extractable functional unit

The equipment is installed on a drawer rack base. It has four positions: working, testing, disconnecting and pulling out. At each position, there are corresponding status indicators and it can be locked at that position.

When changing positions, there are corresponding position change indicators in front of the switch. It can maintain the lP20 protection level in all positions.

This solution greatly simplifies the maintenance of high-power equipment. It can be used as an incoming line, connection and power distribution circuit.

Such as DW17, DZ20, DW15, etc. Cabinet frame circuit breakers can also choose DW45, CW1, AE, M, F, etc. Molded case circuit breakers can choose DZ253, TM30, NS and other more advanced electrical components at home and abroad.

"HD13BX and HS. The 13BX type rotary operation knife switch is a dedicated component specially designed to meet the unique structural requirements of the GGD cabinet. It has changed the operation mode of the mechanism while retaining the advantages of the old product, and is a new type of practical electrical component.

If the design department selects new electrical components with better performance and more advanced technology based on the user's needs, due to the good installation flexibility of the GGD cabinet, it generally will not cause manufacturing and installation difficulties due to the update of electrical components.

To further enhance the dynamic stability of the circuit, the busbar support of the GGD cabinet adopts dedicated ZMJ type combined busbar clamps and insulating support components. The busbar clamp is made of high-strength, high-flame-retardant PPO composite material through thermoplastic molding. It features high insulation strength, good self-extinguishing performance, and a unique structure. It can be conveniently combined into single or double busbar clamps by simply adjusting the modular interblocks. The insulating support is of a sleeve molded structure, which is low in cost, high in strength and solves the defect of insufficient creepage distance of the old products.

Structural features

The cabinet of the GGD type AC low-voltage distribution switchgear complete set adopts the form of a general cabinet. The frame is assembled with C-shaped profiles. The frame parts and special matching parts are produced and supplied by our company to ensure the accuracy and quality of the cabinet. The components of the universal cabinet are designed based on the module principle and have 20-module installation holes, with a high universal coefficient. It enables the factory to achieve pre-production. It not only shortens the production and manufacturing cycle but also improves work efficiency.

When designing the GGD cabinet, the heat dissipation problem during the operation of the cabinet body was fully considered. There are different numbers of heat dissipation slots at both the upper and lower ends of the cabinet. When the electrical components inside the cabinet heat up, the heat rises and is discharged through the upper slot holes, while cold air continuously replenishes the cabinet through the lower slot holes, forming a natural ventilation channel from bottom to top in the sealed cabinet, achieving the purpose of heat dissipation.

The GGD cabinet is designed in accordance with the requirements of modern industrial product shape design, adopting the method of the golden section ratio to design the cabinet body shape and the division dimensions of each part, making the entire cabinet elegant and generous.

The cabinet door is connected to the frame with a rotating shaft type movable hinge, which is convenient for installation and disassembly. Each folded edge of the door is embedded with a mountain-shaped rubber and plastic strip. When closing the door, the insert strip between the door and the frame has a certain compression stroke, which can prevent the door from directly colliding with the cabinet and also improve the protection level of the door.

The instrument door equipped with electrical components is connected to the frame with multiple strands of soft copper wire. The installation components inside the cabinet are connected to the frame with knurled washers, and the entire cabinet forms a complete grounding protection system.

The surface of the cabinet body is treated with high-pressure electrostatic powder coating process. It has strong adhesion and good texture. The entire cabinet is in a matte tone, avoiding the glare effect and creating a more comfortable visual environment for the on-duty personnel.

The top cover of the cabinet can be removed when necessary to facilitate the assembly and adjustment of the main busbar on site. Lifting rings are installed at the four corners of the cabinet top for lifting and transportation.

◆The protection grade of the cabinet body is IP30. Users can also choose between IP20 and P30 according to the requirements of the usage environment.
