Method and device for 10 kV electrified work for breaking lead on falling type fuse

Abstract

The invention relates to a method and device for 10 kV electrified work for breaking a lead on a falling type fuse. A lead insulation fixer is adopted for fixing the lead and a main wire, and the method and device are suitable for the work manner that a lead connecting clamp is adopted in lead lap joint. The lead insulation fixer is composed of a clamp body, an insulation handle and a hinge pin. The clamp body and the insulation handle which are of the integral type are symmetrically fixed together through the hinge pin, and a clamp-shaped structure is formed. A wire fixing groove and a lead fixing groove are formed in the clamp body. Compared with the prior art, the method and device for the 10 kV electrified work have the advantages that a novel tool is adopted and the electrified working method is improved, so that labor intensity is lowered, working risks are avoided, and habituation violation work is eradicated; in practical application, the safety accident rate of 10 kV electrified work for breaking the lead on the falling type fuse more than 200 times all the year round is zero, and safety is high; operation is convenient, working efficiency is improved, the method and device for the 10 kV electrified work are suitable for an insulation glove work method and an insulation rod work method, the tool utilization amount is reduced, and the power supply reliability is improved.

Description

technical field [0001] The invention relates to the technical field of disconnection and disconnection of drop-out fuses of distribution lines in power grids, in particular to an operating method and device for disconnecting the upper leads of drop-out fuses with live voltage of 10kV. Background technique [0002] 10kV live drop-out fuse lead wire operation is a simple live work project, usually completed by one person, but in a long period of operation, it was found that the following disadvantages existed in the previous operation method: 1) The operator removed the lead wire that overlapped with the lead wire After clamping, hold the wire with one hand and the lead wire with the other hand, and disconnect the lead wire when the lead wire and the wire are not reliably fixed. If the insulating gloves are damaged during the operation, it is easy to cause a person to be strung into the circuit during the lead wire lapping process. , causing electric shock injury, this method ...

[0002] 10kV live drop-out fuse lead wire operation is a simple live work project, usually completed by one person, but in a long period of operation, it was found that the following disadvantages existed in the previous operation method: 1) The operator removed the lead wire that overlapped with the lead wire After clamping, hold the wire with one hand and the lead wire with the other hand, and disconnect the lead wire when the lead wire and the wire are not reliably fixed. If the insulating gloves are damaged during the operation, it is easy to cause a person to be strung into the circuit during the lead wire lapping process. , causing electric shock injury, this method has a great risk of operation, and there are also common habitual violations; 2) when the operator removes the overlap between the lead wire and the wire, he must first control the lead wire holder to fix the lead wire, and then remove the lead wire and the wire overlap; This operation process is difficult for operators to operate, and the labor intensity is high; 3) The current parallel hook clamp structure is easy to cause wire jamming or lead wire breakage during installation, especially when spring pads are connected to large diameter wires. It must be dismantled during lead-in. Since the spring pad iron is very small, it will bring great inconvenience to live workers when dismantling it, so it is not suitable for live work.
