Embodiment
Below in conjunction with accompanying drawing present embodiment is described further
By Fig. 1-4 as can be known, isolating switch handle 9 is connected respectively by rotating shaft 11 with cam 10.The syndeton of rotating shaft and handle is the hexagonal structure type of attachment, and cam and rotating shaft are to mill flat form with six circumference axles to be buckled together; Cam and drive link 7 are connected together by bearing pin, and drive link is fixing by two retainer rings 1, can rotate, and two blocks 2 and two locking clips 4 and two retaining hoops 8 are separately fixed on the drive link 7; Two retaining hoops block drive link and prevent axial endplay; Two lock dogs are separately fixed on the little axle on the boxboard and can rotate, and it has an inside pulling force under the pulling force of spring 5.The button 12 on isolating switch handle top has the outwards power on top under the effect of button spring 13, its front end withstands travel switch 14, the switching of control travel switch; Two door shield pieces are separately fixed on the quick operating valve.Isolating switch 15 is installed in the rotating shaft 11.
The isolating switch handle adopts cam control drive link, the locking of drive link control block; The back lock dog that opens the door blocks locking clip and pins drive link under the pulling force of spring, drive link pins cam, and then pins the purpose of isolating switch handle.Can open door after playing outage, open automatic blocking behind the door, door shield piece 3 is pressed to lock dog 6 at closing time, closing behind the door could release, both can switch on, and pins the interlock of door simultaneously, in addition under door opening state, when closing wherein any single door, isolating switch 15 is not opened yet.
Left quick operating valve 17 and right quick operating valve 16 and two quick operating valve door shield pieces 3 promoted two lock dogs, 6 tops when door was in closed condition to the centre, and two lock dogs 6 break away from two locking clips 4 respectively, and locking clip 4 can rotate with drive link 7, and namely isolating switch handle 9 can be pulled; It is invalid to close a door, about only closing two, isolating switch handle 9 is pulled to opening, the main circuit energising, at this moment button 12 ejects under the effect of button spring 13, travel switch 14 is in makes the connection of vacuum contactor control loop electric current that electricity condition be arranged; Isolating switch spanner 9 is pulled to opening, and after the main circuit energising, drive link drives block 2, each dog back block 3 of left and right door, each one of left and right door, block 2 is pinned respectively about two can not slide, two quick operating valves are not opened, and realize the purpose of energising latching door; Button 12 is for behind the ejection state, and it is that the control loop electric current is connected that travel switch 14 is connected, the starter motor work of can switching on after the vacuum contactor start button starts; Press the button 12 earlier before opening the door, travel switch 14 is in makes vacuum contactor control loop failure of current, off-position, button 12 front ends are separated from the recess of cam 10, and at this moment isolating switch spanner 9 can be pulled; With isolating switch spanner 9, pull to cutting off de-energized, at this moment drive link 7 drives each one disengagement of block 2 left and right doors door shield piece 3, and respectively one of left quick operating valve 17 right quick operating valve 16 are opened after door just can slide, and realize the purpose that can open the door after the outage;
After opening the door, door shield piece 3 is separated from lock dog 6 at a left quick operating valve left side 17 and each one of right 16 right quick operating valve two quick operating valve, each one of left and right door, lock dog 6 is under the effect of spring 5, block each one of locking clip 4 left quick operating valves 17 and 16 liang of quick operating valve of right quick operating valve downwards, locking clip 4 is fixed together with drive link 7, and drive link 7 blocks cam, 9 switchings of isolating switch spanner are motionless, can not give electricity, both play the outage back pullout (BPO), can not connect the purpose of power supply after opening the door.And then the preceding outage that realizes opening the door, cut off load simultaneously earlier, prevent from that the isolating switch band carries to cut off the electricity supply and produce electric arc that the outage back pullout (BPO) can not be connected power supply under the door opening state, the isolating switch plate changes motionless purpose.
