Description

[0002] At present, with the rapid development of China's economy and society, the requirement for line live working is also higher and higher, and the non-stop power operation is also universally recognized by the society. The non-stop power operation of 10kV distribution network overhead line can not only ensure the reliability of power supply and the safety of power grid, but also effectively control the power failure, improve the power supply reliability, and ensure that the personnel in the non-fault area can normally use electricity. It has practical significance for the operation and maintenance of 10kV distribution network and the repair work. In the process of unfolding the lead lapping work in the live working, the parallel groove clamp needs to be installed on the wire of the power grid first, and then the lead is clamped into the buckle of the parallel groove clamp by using the insulating clamp device, so that the wire and the lead clamp are connected through the parallel groove clamp. However, the insulating clamp device in the prior art is time-consuming and laborious, and the operator uses it inconveniently, which hides a safety hazard for live working.

[0003] In the prior art, the utility model discloses a labor-saving insulating clamp device, and relates to the technical field of power operation auxiliary tools, which comprises a fixed rod, an operating rod and a clamp device. The clamp device comprises a fixed clamping mechanism and a movable clamping mechanism for controlling clamping or loosening. The operating rod is inserted into the fixed rod, one end of which extends to the bottom of the fixed rod, and the other end is connected with the movable clamping mechanism through a movable rod mechanism, which is used for controlling the clamping or loosening of the movable clamping mechanism. The utility model has the advantages of simple structure and convenient operation. The operating rod can control the movable clamping mechanism to clamp and loosen the lead conveniently and quickly, and the convenience of the power operation operator is improved.

[0004] In order to further improve the non-stop power operation rate of distribution network, ground potential live working (i.e. pole climbing live working) needs to be carried out in places where the live car cannot reach. However, when carrying out ground potential operation, it is often difficult to find a good wire clamping angle due to the limited activity range after climbing the pole. A lot of time is often consumed to clamp the wire, and sometimes it is impossible to carry out ground potential operation because the wire clamping angle cannot be found. At the same time, the existing insulating clamp rod is not convenient for clamping the wire, and the clamping force is not reliable enough, which may cause the wire to fall off the clamp, or a lot of time is needed to clamp the wire because the opening of the clamp is too small.
