Disconnecting link and close grounding switch in equipment both sides, being fitted without when grounding switch or grounding switch can not close for some reason needs people
Frock sets ground wire.The 500kV ground wire multidimensional spiral compression formulas of AC Substation at present, need first by ground wire during installing
Wire clamp is suspended on corresponding primary equipment, then compresses wire clamp by turning insulating bar.500kV is opened in usual AC Substation
Close field primary equipment average height more than 9 meters, 500kV earth wire insulating rods are divided into 5 sections, total length at 8.5 meters or so,
The weight of single-phase earthing line is more than 30 kilograms, and slight bending deformation, operations staff can occur during upper act for insulating bar
It is difficult to single-handedly ground wire is suspended on corresponding primary equipment.In the market without special ground wire suspension arrangement, only
The equipment such as some portable lift, high-altitude operation vehicles, it can not be used directly to suspension ground wire.Common lift can not
The insulating bar of dead earth line, also now make insulating bar transverse shifting without satisfaction, and hang up properly the fastening after bar, release function.Profit
Need staff being sent to relevant position by high-altitude operation vehicle with high-altitude operation vehicle suspension ground wire, then artificial suspension,
This allows for human body close to unearthed conductor, there is potential safety hazard.
Utility model content
The purpose of this utility model is the shortcomings that overcoming above-mentioned prior art, there is provided one kind can be completed to connect by the device
The overall process that ground wire is assembled, elevated, hanging, tightening, removing, solve in the difficult one kind of transformer station's suspension 500kV ground wires
It is grounded suspension arrangement.
The utility model is achieved through the following technical solutions：
One kind ground wire suspension arrangement, including spiral compression formula insulating bar, lowering or hoisting gear, special fixture；Described is special
Fixture is arranged on lowering or hoisting gear with its elevating movement, and described special fixture is used to clamping spiral compression formula insulating bar and can horizontal stroke
To the position of regulation spiral compression formula insulating bar；Described special fixture includes base support, slide rail, the first electric pushrod, the
Two electric pushrods, clamp base；Described slide rail is arranged on base support, and described clamp base is horizontally arranged at described
It can reciprocatingly slide on slide rail and on slide rail；The first described electric pushrod is arranged on base support, the first electric pushrod
Movable end is connected control clamp base with clamp base and moved back and forth on slide rail；The principle slide rail in described clamp base
Side is provided with the clamping through hole for spiral compression formula insulating bar, and the first grip block is provided with the edge of clamping through hole side,
Clamping through hole is provided with the second described electric pushrod, the movable end of the second described electric pushrod away from the side of the first grip block
It is provided with the second grip block and the grip block of face first；For described spiral compression formula insulating bar through clamping through hole, second is electronic
Push rod promotes the second grip block spiral compression formula insulating bar is critical between the first grip block and the second grip block.
As the improvement of such scheme, the bottom of described lowering or hoisting gear is provided with earth point.
As the improvement of such scheme, described lowering or hoisting gear is provided with pushing hands.
The utility model has the advantages that：
1st, transformed on the basis of movable lifting machine, special fixture, fixture control are installed on the top of liter arm
Loop is connected on lift base by cable, and operating personnel can be in ground remote control control fixture.
2nd, whole jig Design for can transverse shifting, can realizes insulating bar after fixture clamps the insulating bar of ground wire
Transverse shifting, convenient suspension ground wire.The transverse shifting of fixture can also pass through remote control control.
3rd, the first segment of insulating bar is put into clamp, the second section of insulating bar is screwed on after longitudinal direction rise certain distance,
Whole 5 sections of insulating bars are installed by that analogy.Fixture fixes the top of insulating bar, ensures that its top does not bend deformation.So
Insulating bar is longitudinally increased to corresponding earth point afterwards, then controls fixture transverse shifting, the wire clamp of ground wire is hanging to corresponding one
On secondary device.
4th, after ground wire is hung up properly, operating personnel suitably unclamp special fixture, by turning insulating bar, its wire clamp is clamped completely
Primary equipment, fixture is then totally released again, withdraw and rise arm, it is possessed certain defencive function, prevent insulating bar wire clamp from not hanging
Drop and hurt sb.'s feelings well.
5th, scene there may be faradic situation after being raised in view of device, and earth point is provided with crust of the device,
Device is grounded in itself by being grounded, prevents induced electricity from hurting sb.'s feelings.
