1,Summary


110KV outdoor single-column type neutral point disconnecting switch


Series GW8 (GW8-35, GW8-63, GW8-110, GW8-40.5, GW8-72.5, GW8-126 type) , series GW13 (GW13-35, GW13-63, GW13-110, GW13-40.5, GW13-72.5, GW13-126 type) The disconnecting switch of neutral point unipolar exchanges 50Hz outdoor high-pressure electric apparatus, offer the neutral point of voltage transformer in cases there is voltage to be non-loaded, connect Herba Euphorbiae Humifusae to the intersection of voltage transformer and neutral dot and line go on, divide into and shut use, thus realize the intersection of voltage transformer and neutral earth or two kind non-grounded freedom switch of run mode.

GW8, GW13 series the intersection of neutral point and disconnecting switch can apolegamy manual or electronic actuating mechanism according to the request of user.

3,Main frame of the products 110KV outdoor single-column type neutral point disconnecting switch


3.1 GW8, GW13 neutral point disconnecting switch are made up of base, pillar electrical insulator, electric conduction arranging, stylus, wiring board,etc..
3.2 Have stylus and interstar connection that is pulled in the pillar electrical insulator upper portion, there are connecting levers and connecting rods in the underpart. The actuating mechanism, through the output toggle arm, connecting rod, bearing connecting lever,etc. drives and isolates the disconnector to do dividing, switching-in sports.
3.3 Touching the pretext 3 to make up contact finger, contact finger spring and contact finger stand three part of disconnecting switch.

4,Installation
4.1 Push the intersection of switching-in and position to by hand the intersection of disconnecting switch and body, electronically (manually) The actuating mechanism installs in place, and reach the actuating mechanism manually the position of switching-in, connect the good actuating linkege according to the real required length, make the organization guarantee the reliable disintegration of the switch blade when in the position of divide-shut braking, fasten every fastener of joint finally.
4.2 measures the resistance of major loop of the disconnecting switch and should be demonstrated in the table below and enclosed:
110KV outdoor single-column type neutral point disconnecting switch
5,Operating mechanism characteristic
1,Practicability is strong
It can be in & ldquo that 1.1 organizations power on; & rdquo in situ; Or & ldquo; & rdquo of long distance control; Operate, an electrical machinery passes the two-step worm reducer output torque, can drive the disconnecting switch or earthing switch, accurate, reliable realization switching-in, separating brake movement;
1.2 utilizes the journey (inch) On off control actuating mechanism exports the corner or final position which it operates. Utilize worm gear drive of the endless screw to guarantee required output torque and speed, this organization operates steadily, impact force is little, the noise is low, and have reliable auto-lock functions;
1.3 organizations can realize and hand operation electronically separately, electronically and hand kinetic energy interlocking;
1.4 utilizes control electric machine automatic power off of the time relay, prevent the fault-operation;
1.5 container bodies are the welded construction of corrosion resistant plate. Its appearance is esthetic, reasonable structure, have reliable waterproof, dustproof, antisepticize and corrosion proofing characteristic. Can suit to various regions, light and handy and esthetic.
2,Economy
2.1 need mains voltage to operate, does not need other accessory;
2.2 mechanism spare part standardized intensity is high, benefit processing and manufacturing;
2.3 product costs are reasonable.
3. Safeguard, check simply
3.1 copies of actuating mechanism are simple in construction, convenient maintenance is apt to walk, the spare part? ? ? There is compatibility;
3.2 organization inner bearing and two-step worm reducer are all the structure of sealed type, adopt the grease lubrication, non-refuelling, non-maintaining;
3.3 opens the main entrance or side door, can safeguard and check conveniently.
