The active force of torsional spring 722 is oppositely arranged.When driving shaft 442 drives divide-shut brake sliding piece 725 to rotate to combined floodgate direction, divide-shut brake
Sliding piece 725 depresses the tabletting 724 of combined floodgate travel switch component 727, starts combined floodgate travel switch component 727, to make SF6
Arc-chutes 7 close a floodgate, and divide-shut brake sliding piece 725 continues to rotate to combined floodgate direction later, and divide-shut brake sliding piece 725 is detached from combined floodgate stroke
The tabletting 724 of switch block 727 makes the tabletting 724 return back to horizontal position；When driving shaft 442 drives divide-shut brake sliding piece 725
When rotating to separating brake direction, the tabletting 724 that divide-shut brake sliding piece 725 stirs combined floodgate travel switch component 727 is moved upwards, but not
Combined floodgate travel switch component 727 is triggered, the tabletting 724 of separating brake travel switch component 727 is depressed later, makes separating brake travel switch group
Part 727 starts, and makes SF67 separating brake of arc-chutes.
When extra-high-voltage earthing switch of the invention closes a floodgate, operator lock 4 and moving arcing contact 6 are put from horizontal position upwards together,
When close to closing position, moving arcing contact 6 contacts static arc contact 5, the divide-shut brake sliding piece in arc-chutes toggle mechanism 720 first
725 press travel switch under the drive of driving shaft 442, so that arc-chutes operating mechanism 719 be made to drive SF6Arc-chutes 7 close a floodgate,
Arc-chutes 7 close induced current, and induced current is connected in subsidiary loop, and lock 4 of then operating closes a floodgate, and continue induced current by leading
Disconnecting link 4 carries；When grounding switch tripping, operator lock 4 is first separated, and induced current is transferred in subsidiary loop, is dialled in divide-shut brake
Another travel switch is pressed under the actuating of movable plate 725, and SF is driven by arc-chutes operating mechanism 71967 separating brake of arc-chutes, arc extinguishing
Induced current is cut-off in room 7, and then dynamic and static arcing contact 5 separates, and moving arcing contact 6 moves to horizontal position with the operator lock 4 together bottom
