Distribution network live work drainage device based on remote control

Abstract

The invention relates to a mounting device for an overhead line or a cable, in particular to a remote control based network-distribution conduction device for live working. The structural feature of the network-distribution conduction device comprises a pair of clamping devices, a high-voltage insulation connection wire and a remote control unit. The clamping devices in the conduction device is remotely controlled by a remote control unit so as to clamp and loosen, the operation program of an operator is simplified, a series of inconvenient and unsafe problems brought due to the local operation of the operator are avoided, and meanwhile, the operation reliability problem brought by remote distance manual operation is avoided; the work pressure of the operator is reduced, and the safe production is guaranteed; and moreover, as a speed-down motor is adopted, a balanced clamping action force is exerted to a guide line, so that the problems that the guide line is damaged due to the facts that the force exerted by manual work is uneven, and the direction is deviated, are avoided; and the radian symmetry structure of a movable jaw and a bridge-shaped fixed jaw can adapt to the surface radian of the guide line, and a good surface contact is provided, so that a positive pressure is exerted to the guide line, and the damage problem of the guide line is further solved.

Description

technical field [0001] The invention relates to an installation device for overhead lines or cables, in particular to a remote control-based live work drainage device for a distribution network. Background technique [0002] In the existing technology, most projects of live work need to use line diversion technology, such as on-load breaking knife switch, on-load transfer line, on-load handling defects, etc., and there are two kinds of diversion technology solutions commonly used on-load and live electricity: one The first is a simple clamping device, which connects the two ends of the faulty line section and replaces the original wire for shunting, so that the faulty line can be cut off and the fault can be repaired. The line operation is safe and reliable, and it is suitable for single-point fault and short-distance line defect treatment. The other is the flexible cable system for bypass operation. The bypass operation system is a new type of distribution network maintena...

Problems solved by technology

[0003] Among the above-mentioned technical solutions, no matter what kind of solution it is, it is necessary to operate the fixture or joint close to the operator. The operator needs to keep a sufficient safety distance from the charged body to ensure that the operation procedure is correct and the action is standardized during the operation, otherwise the operator cannot be guaranteed. Personal safety and reliable operation of the distribution network, so higher requirements are placed on operators, which brings greater operating pressure to operators, which is not conducive to safe production

On the other hand, because the clamps or joints in the prior art adopt an open clamping scheme, or simple clamping equipment, or remote manual operation (for example, an insulating operating rod is used to cooperate with a transmission mechanism with a screw), it causes its contact with the wire The reliability of the connection is often not guaranteed, and the manual operation often has uneven operating force and swaying operation direction. In addition, if some line contact is used instead of surface contact between the fixture or joint and the wire, it is easy to make the wire in the operation process. Or it will be damaged during repeated operations, which will increase the instability of distribution network operation
