Products sort

1.Product can be sorted three models according to voltage degree: 40.5kV, 72.5kV, 126kV.

2.Product can be sorted four models according to current degree: 640A, 1250A, 1600A, 2000A,

3. Product can be sorted four models according to attached installing earthing switch: no earthing, left earthing, right earthing, double earthing. The attached installing earthing switch can be sorted two models according to short circuit current capacity: I earthing switch, n earthing switch. And dynamic short-time withstand value of n earthing switch is the same as disconnecting knife’s.

Product structure and Working principle

1. Structure

GW5 IH disconnecting switch(Fig.2, Fig.3) is composed of three single poles, operating mechanism and transmission parts. Each single pole is set in an I – shaped frame, composing of underplate, axletree seat, support insulation, connection seat, left and right contacts, earthing static contact and earthing switch knife and so on.

Main knife of three phase ac switch is combined with CS171V series human mechanism; it also can be combined with CJ6 or CJ2-XG.; earthing knife is combined with CS171V series human mechanism. When human operating mechanism combines with electromagnetic lock, electric interlock among disconnecting switch, earthing switch and breaker can efficient achieved, avoiding incorrect operation.

2.Opening operation

I.Main knife working principle

The operation of gw4 is connected with switch main shaft through vertical transmission rod, joint and universal joint, and connected with each separate single pole through joint and link rod, so that it achieve synchronous act of the three single poles.

2.Earthing knife working principle

Three single-pole earthing knives are connected through three single-pole transmission rods. Main shaft of operating mechanism is connected with one set of space four-connection rods through vertical transmission rod and joint. When the mechanism acts, closing and opening operations of earthing knife are achieved through vertical transmission rod and space four-connection rods.

3.Auxiliary switch working principle

The auxiliary switch of operating mechanism is linked with main shaft of mechanism. Break or close the relevant contacts when act opening or closing, and give the relevant signals.

4.Main, earthing knives mechanical lockout

When both of main, earthing knives are combined with human operating mechanism, the interlock between eathing switch and disconnecting switch is achieved through interlock board of mechanism. When main knife operating mechanism is combined with electric mechanism, the interlock between eathing switch and disconnecting switch is achieved through interlock board between disconnecting switch and earthing knife rotation axis.
