Description

The high-voltage earthing wire clamp

The utility model relates to a kind of high-voltage earthing wire clamp, or rather, relates to a kind of 500KV high-voltage earthing wire clamp.

The high-voltage earthing wire clamp is high-tension circuit when maintenance one of security apparatus commonly used, and it couples together power supply and the earth temporarily, and is former thereby cause unexpected incoming call that the maintainer is caused danger owing to misoperation etc. with the power circuit that prevents to have had a power failure.High-voltage earthing wire clamp integral body is made up of wire clamp, earth connection and earth electrode usually, and wherein wire clamp is its critical component.Requirement to wire clamp comprises: fabulous conductivity is arranged, and bigger with the contact-making surface of lead, can bear impact of huge short circuit current or the like.

Present employed high-voltage earthing wire clamp all needs to operate to the high-altitude, and it is not too convenient to use, and can not effectively guarantee high pressure check man high-tension line fail safe of incoming call suddenly when wire clamp is operated; The bottom plate of wire clamp and auxiliary splint are generally flat type in addition, and be little with the lead contact area, has potential safety hazard and be easy to damage the outer layer rubber of lead.

In order to solve the deficiency of above-mentioned high-voltage earthing wire clamp, it is a kind of simple in structure, easy to operate that the purpose of this utility model is to provide, big with the contact area of lead, wireplint contacts good high-voltage earthing wire clamp with lead, and just can carry out safety operation to it on ground.

In order to achieve the above object, high-voltage earthing wire clamp of the present utility model is made up of two parts, and a part is the wire-clamping device that contacts with lead, and another part is by the control device of electrician's operation, is linked by a backguy between wire-clamping device and the control device; Wherein wire-clamping device constitutes main body by a bottom plate and an auxiliary splint, and between major and minor clamping plate on the lower side the position fuse by a bolt; Be with a tension spring on bolt, the spring bipod withstands on major and minor clamping plate lower inside; One load pin is respectively arranged on the major and minor clamping plate above the bolt, wherein nailing on one at the force-bearing pin of auxiliary splint can serve as the load bar of axle swing with this load pin, the other end of this load bar has a step, the force-bearing pin that the step of this load bar just is stuck on the bottom plate when wire-clamping device is in open configuration nails on, with the elastic force of opposing tension spring; On the bottom plate below the spring pin, fix the bolt that an afterbody has through wires hole;

Control device is connected by a bolt with handle by a fixed lever in addition, and a backguy end socket groove is arranged above handle, is used for being fixed in this backguy end socket groove with passing backguy one end that through wires hole on the fixed lever extends to handle; After the other end passes the through wires hole of bolt on the bottom plate, be divided into two, one is fixed on the auxiliary splint, another is fixed on the load bar, wire-clamping device opens under usual condition, when handle is operated, twitch backguy and drive the load bar bottom, under the effect of tension spring, make the wire clamp closure, clamp high-voltage conducting wires.

And the major and minor clamping plate and the lead contact position of wire-clamping device are circular-arc.

In addition, be provided with a through wires hole in the bottom plate bottom of wire-clamping device.

Simultaneously, wire-clamping device is made with the good material of conductivity such as aluminium alloy.

Below in conjunction with accompanying drawing a most preferred embodiment of the present utility model is further elaborated.

Fig. 1 is the structural representation of the utility model high-voltage earthing wire clamp wire-clamping device.

Fig. 2 is the structural representation of the utility model high-voltage earthing wire clamp control device.

The utility model is made up of two parts, and a part is a wire-clamping device as shown in Figure 1, and another part is a control device as shown in Figure 2, is fused by a backguy 4 between wire-clamping device and control device.

Wherein wire-clamping device constitutes main body by bottom plate 1 and auxiliary splint 9, the hole 10 that all has an affixed earth lead 11 on the major and minor clamping plate, bottom plate 1 links together with the bolt 5 that auxiliary splint 9 is located on the lower side by its middle part, and major and minor clamping plate can serve as that axle rotates with bolt 5; Be with a tension spring 6 on bolt 5, the bipod of this spring 6 leans the lower inside at major and minor clamping plate respectively.Be circular-arc at major and minor clamping plate and lead contact position; One load pin 2 is respectively arranged on the major and minor clamping plate below the circular arc, wherein on the load pin 2 on the auxiliary splint 9, have a load bar 3, this load bar 3 can serve as the axle swing with the load pin on the auxiliary splint 2, when being in the normal position, load bar 3 just is stuck on the load pin 2 on the bottom plate 1, with the tension force of antagonistic spring 6, make wire-clamping device be in deployed position.

Be fixed with the bolt 7 that an afterbody has a through wires hole in bottom plate 1 bottom with nut 8, and have a through wires hole 12, twitch sensitive to guarantee backguy in the bottom of bottom plate 1.

In addition, described control device constitutes main body by fixed lever 16 and handle 14, and fixed lever 16 and handle 14 fuse by a bolt 13, and can serve as that axle rotates with bolt 13, is provided with a backguy end socket groove 15 above handle 14.

One end of backguy 4 is cemented in the backguy end socket groove 15 of control device, and the other end passes the through wires hole 12 of wire-clamping device and punishes into two at bolt 7, and one is passed through wires hole on the auxiliary splint 9 and fixed on it, and another is fixed on the load bar 3.Wire-clamping device is in open configuration when control device not being operated; When with the manual manipulation control device, handle is twitched backguy 4 and is also driven 3 motions of load bar, makes load bar 3 bottoms, makes the wire-clamping device closure under the effect of tension spring, thereby high-voltage conducting wires is clamped.

Adopt high-voltage earthing wire clamp of the present utility model, as long as backguy long enough, the electrician can stand on the ground high-tension line is carried out clamping, and because earth lead is without control device, make and can not cause danger when in high-tension line, sending a telegram here suddenly, overcome the deficiency of existing high-voltage earthing wire clamp the maintainer, easy to operate, safety, reliable.
