●Trolley room

The trolley room is equipped with a specific guide rail, so that the trolley can slide and work in it. The trolley has a working position and a test position (isolation position). When the trolley enters the working position from the testing position, the valve blocked on the fixed contact box will be pushed open, so that the moving contact of the trolley will be inserted into the fixed contact. When the trolley is pulled out, the valve will automatically drop again, which can prevent the operator from touching the live body. When the trolley is pulled out, the operator can also lock the valve to prevent the trolley from being pushed open and accidents occur. The trolley room can be equipped with circuit breaker trolley, voltage transformer trolley, isolation trolley and meter measuring trolley.

Figure 2 KYN28C switchgear cabinet structure

Busbar room

The design of the bus room fully considers the installation mode of the main bus during the installation construction by users, so that the construction workers can conveniently install the bus by opening the rear baffle plate without climbing to the top of the cabinet.

The baffle plate between the segmented busbar passes through the cabinets is the wall bushing made of insulating and flame-retardant material, which can not only support the main busbar, but also limit the spread of the situation when an internal fault occurs.

Cable room

The cable room has abundant space to install and overhaul current transformers, grounding switches, lightning arresters and cables

The usage of cables can reach up to three to six groups. In the design, the special requirements of users are also taken into account, so that the installation height of the electrical system can reach more than 750mm. See Figure 1 The bottom plate structure of the cable room is also very suitable for construction workers to conveniently install cables.

The control wire of the switchgear itself is laid on the right side, and the control wire crossing hole is opened on the side panel of the instrument room for construction.

●Pressure relief device

There are pressure release devices above the trolley room, bus room and electrical system room. When an internal fault occurs in the cabinet and arcs occur, the sharply rising air pressure will quickly open the release device so that the internal gas can be discharged in time, ensuring the safety of operators and switchgear. cabinets.

KYN28-12

Indoor metal armored center-mounted removable switchgear

When the switch cabinet is working normally, the special structure of the pressure release device can help dissipate heat, so that the temperature rise of each part of the primary circuit in the cabinet can always be kept within the normal working range.

Interlocking device

The KYN28 series switchgear is also equipped with a flexible and reliable five-protection interlocking device, which provides a reliable guarantee for preventing accidents and the safe operation of the equipment. When the grounding switch is in the opening position, the trolley can be pushed from the testing position to the working position, and the circuit breaker trolley can only be pulled-in or pulled-out when it is opened; When the circuit breaker trolley is in the testing position or working position, the closing and opening operation can be carried out; When the trolley is in the working position, the grounding switch cannot be closed and the secondary plug cannot be pulled out; When the grounding switch is closed, the trolley cannot be pushed to the working position.

Grounding device

Connecting the main grounding busbars of each cabinet together with the preset connecting board.
Connecting all the leads to be grounded in the switchgear.

ZBW series combined substations, commonly known as European-style box substations, combine highvoltage electrical equipment, transformers, low-voltage electrical equipment, etc. into compact complete sets of power distribution devices, which are used in urban high-rise buildings, urban and rural buildings, residential areas, high-tech development zones, small and medium-sized factories, mines, oil fields, and temporary construction electricity and other places for receiving and distributing electrical energy in the power distribution system.

ZBW series combined substations have the characteristics of strong complete set, small size, compact structure, safe and reliable operation, easy maintenance, and mobility. Compared with conventional civilbuilt substations, combined substations of the same capacity usually cover an area of only 1/10\~1/5 of conventional substations, which greatly reduces the design workload and construction volume, and reduces construction costs.In the power distribution series, it can be used in the ring network power distribution system, as well as in the dual power supply or radiation terminal power distribution system. It is a new type of complete set of equipment for the construction and re-selection of urban and rural substations.

ZBW series combined substations meet the standards of SD320-1992 "Technical Conditions for Box-type Substations" and GB/T17467-1997 "High-voltage/Low-voltage Prefabricated Substations".

Product structure characteristics

1. This product is composed of a high-voltage power distribution device, a transformer and a low-voltage power distribution device connected, and is divided into three functional compartments, namely a high-voltage chamber, a transformer chamber and a low-voltage chamber. The high- and low-voltage chambers are fully functional, and the high-voltage side primary power supply system can be arranged into a variety of power supply methods such as ring network power supply, terminal power supply, and dual power supply. High-voltage metering devices can also be installed to meet the requirements of high-voltage metering. The transformer room can choose from S9 and S11 series low-loss oil-immersed transformers and SC(B) 9, SCR9, SC(B)10, and SCR10 series dry transformers; the transformer room is equipped with a self-starting forced air-cooling system and a lighting system, and the lowvoltage room can adopt a panel or cabinet-mounted structure according to user requirements to form the power supply scheme required by the user. There are various functions such as power distribution, lighting distribution, reactive power compensation, electrical energy metering and power measurement to meet the different requirements of users, and to facilitate users' power supply management and improve power supply quality

2. The high voltage chamber has a compact and reasonable structure, and has a comprehensive “five-protection' interlocking function to prevent misoperation. When the user has requirements, the transformer can be equipped with a track to easily enter and exit from the gates on both sides of the transformer room, and each room has automatic lighting devices. In addition, all the components selected in the high and low voltage rooms have reliable performance, easy operation, safe and reliable product operation, and easy operation and maintenance.

3. Two methods of natural ventilation and forced ventilation are used to make the ventilation and cooling good. Both the transformer room and the low-voltage room have ventilation ducts, and the exhaust fan has a temperature control device, which can be automatically started and turned off according to the set temperature to ensure the full load operation of the transformer.

4. The structure of the box can prevent rainwater and dirt from entering. It is made of special steel plate or aluminum alloy plate, which is anticorrosive and has the conditions for long-term outdoor use. Ensure anticorrosion, waterproof and dust-proof performance, long service life, and beautiful appearance.
