结构简述

Briefdescription ofstructure

GW4H-series disconnectors consist of three single-pole units and operatingmechanisms.Each single-poleunit iscomposed of a base,post insulators and conductive parts.Rotatable insulating posts are mounted at both ends of the long base.The finger arm and contact arm of the conductive blade are respectively fixed on the top of the insulating posts.

The operating mechanism drives one-end insulating post to rotate, and drives the other-end insulating post to rotate reversely by 9 0 ^ { \circ } through cross-link rods. Consequently,the conductive blade rotates on the horizontal plane to realize the opening and closing operations of the disconnector.A horizontal insulating break is formed under the open condition.

Main conductive system

Thecontactfingersare madeofspecialcopper-alloymaterial,featuring excellent rigidityand high-temperature resistance.Thecontact systemadoptsspring-free design;thecontactfingers requireno spring compression.Their elasticityremains stable during long-term operation,and thecontact pressre keeps unchanged throughout the servicelife.Meanwhile,both contactfingersand contactsare treated with specialaviation-gradedry lubrication. No grease lubrication isneeded,realizing cleanoperation,maintenance-free performanceand long service life. Three-self contact structure (self-cleaning,self-force,self-holding)
During opening and closing operations ofthe main disconnector and earthing switch,theconductive surfaces can beautomatically cleaned to achieve favorable contact performance.
Under normal operating current,the contact resistance of the main conductive system is maintained by contact pressure generated from the inherent elasticity of contactmaterials.
When short-circuit current flows through,additional contact pressure between contact rods increases with rising current.It ensures that contacts willnot bounce off under strong electrodynamic forceevenat heavy current, maintaining consistently low contact resistance and temperature rise.

GW7H-252 High-Voltage Disconnector

ProductOverview

TheGW7H-252 high-voltage AC disconnector is of the same type as GW7, adoptinga three-column horizontal double-break structure.All components ofthis disconnector are made of full-aluminum and full-stainless-steel materials.It adopts one-step forming process without welding spots or welding joints,realizingmaintenance-freeand overhaul-freeperformance. The main conductive system adopts copper-chromium alloy self-energizing silver-plated contact rods,which can keep the contact pressure between contacts and contact rods unchanged for a long time.Years of operation experience has verified that the unique self-energizing contact system features excellent self-cleaning capacity as well as long-term operational reliability and stability.

Mechanical interlockisprovided between the main switch bladeand the earthingswitch.Themain switch bladeisequipped with CJ6A typeelectric operatingmechanism;the earthing switchis fitted with CS20 or CS17G5 type manual operating mechanism.

Technical Parameters

GW7H-252DW/2500A High-Voltage Disconnector in-site operation

GW7H-252High-VoltageDisconnector

Technical Features

Themain conductive system adoptscopper-aluminum alloy self-energizing contact rods,which overcomes the disadvantage of easy rusting of carbon steel wire springsand canmaintain constant contact pressure between contacts and contact rods for a long time.The contact rods adopt special silver-plating technology,which effectivelyavoidsdustaccumulation caused by lubricant coating at this position and the consequent increase of contact resistance.The matching of contact rods and contacts forms the contact system of the main blade.Years of operation experience has proved that the unique design of self-energizing contact system delivers excelent self-cleaning performance as well as long-term operational reliabilityand stability.

The conductive tube ismadeof high-strength forged aluminum tube,featuring high current-carrying capacityand good heat dissipation performance. The surface of the conductive tube is treated by anodizing process for superior corrosion resistance. Anti-rust aluminum alloy shielding covers areinstalled at the opening-closing positions ofmovingand fixed contacts aswell as at the upper end of insulators.The electric field at conductive parts becomes more uniform, the insulationlevelisgreatly improved,and the radio-interference levelissignificantly

The bearing housing is made of high-strength aluminumalloy casting,and the flange shaft is made of stainless steel to avoid outdoor corrosion.A double-seal structure is adopted to ensure long-term contact between molybdenum disulfide grease and bearings inside the bearing housing cavity.It eliminates bearing corrosion and jamming,ensures long-term flexible rotation of the disconnector,and realizes true maintenance-free operation.

Thisproduct extensively adopts high-strength aluminum profiles,featuring stable quality,short production cycle, excellent corrosion resistance and attractive appearance.

All jointsand rotating pins of the base transmission part are made of stainless steel.The bearings are made of polytetrafluoroethylene (PTFE),which effectively prevents corrosion and jamming of rotating parts under long-term outdoor operating conditions.Similar to the main conductive circuit,the earthing switch adopts self-energizing contact rod structure with simple structure and reliable performance.The three-phase horizontal connecting rod is equipped with U-bolt pressure-plate type connectors without welding,facilitating installation and adjustment.The vertical connecting rod adopts clamp-type structure,and connects with the operating mechanism via pressure-plate type connectors.It allows stepless adjustment and delivers large transmission torque.

* Themain contacts feature self-cleaning and ice-breaking capacity，and the contactsare automatically clamped when short-circuit current passes through.
* The finger contacts are fixedly connected with contact bases to form a stable conductive path.
* The contact finger springs are equipped with insulating plugs to prevent spring shunt current.
* Withoutlatch plateson contact heads,the moving contact plateis locked afterclosing.Thecontacts willnot disengage even under externalforces such as strong wind,earthquake and electromagnetic force.
* The arcing contacts endow the disconnector with excellent performance for bus-transfer current switching as

well as switching of small inductive and capacitive currents.

Reliable-contactFixedContact

Forthe fixed contacts installed on the topof fixed post insulators on both sides,one side of each finger contact is fixed to the contact base to form a stable current path;on the other side,pressure is applied to the moving contact by springs and the self-elastic force of finger contacts to achieve reliable contact. The arcing finger contacts serve for closing buffering and arc striking.

Two-step-movement Main Blade

Whenthe central rotating post insulator rotates towards the closing direction, the operating disc (9) and rotating plate (8) on the top of the insulator drive the conductive tube (2) to swing about 7 0 ^ { \circ } in the horizontal plane.After the moving contact plates (l)at both ends of the conductive tube enter between the finger contacts of fixed contacts and are blocked by the stop blocks,the rotating plate (8) continues to rotate.Via the ball shaft(lO),it drives the shift fork (4) to make the conductive tube self-rotate by about 4 5 ^ { \circ } ,so that the moving contactplatesarereliablycontactedwithfixedfingercontacts and locked by latch plates.The positioning spring(7)at the end of the shift fork provides self-locking for opening operation.

GWSeries Neutral-point Disconnectors

MainTechnicalParameters

MainFeatures

Both GW8 and GW13 types have undergone structural improvement to upgrade the parameters of rated currentand short-time withstand current.

The conductive arm is made ofrectangular aluminumalloy,featuring high mechanical strength,light weight,large heat-dissipationareaand goodcorrosionresistance. Self-elastic contact fingers made ofspecial copper alloyareadopted.The contacts are clamped by the inherent spring force ofcontact fingers,which avoids the vicious circle caused by spring corosion and thermal annealing,such as reduced contact clamping force,increased contact resistance and aggravated contact overheating. The contact fingersare bolted to the contact base to prevent oil dirt and dust from entering contact points and maintain stable contact resistance.The contacts are bent from copperplates withshort friction travel against contact fingers during opening and closing,resulting inlow operating force.This conductive structure has obtained national utility-model patent.

Rotating parts are designed for maintenance-free operation.The rotating base adopts sealed structure to block moisture,dust and harmful gases,so that the bearing worksunder favorable conditions.No.2low-temperature grease is applied to preventbearing rust as wellas grease loss and drying-up.All rotating frictionpositions adopt the matching structure of stainless-steel pins and oil-free self-lubricating bearings.Steel componentsare hot-dip galvanized to ensure flexible operation,reliable performance and maintenance-free service of the disconnector.
