Method and device for 10 kV electrified work for connecting lead of branch connecting circuit

Abstract

The invention discloses a method for 10 kV work for connecting a lead of a branch connecting circuit. A lead insulation fixer is used for fixing the lead and a main wire, and a double-screwing type connecting and leading wire clamp is used for conducting lead lap joint work. 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 integrated are symmetrically fixed together through the hinge pin to form a clamp-shaped structure. The double-screwing type connecting and leading wire clamp comprises a fixed hanging piece, a wire screwing mechanism and a lead screwing mechanism, the wire screwing mechanism and the lead screwing mechanism are connected with the fixed hanging piece through screws respectively. Compared with the prior art, the method has 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; safety is high in practical application; the double-screwing type connecting and leading wire clamp is adopted, operation is convenient and fast, the method is 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 power grid distribution line branch connection wiring, in particular to an operation method and a special device for 10kV live connection branch connection lead wires. Background technique [0002] 10kV live connection and branch line lead wire work is a simple live work project, which is usually completed by one person. However, during a long period of operation, it was found that the following disadvantages existed in the previous operation method: 1) The operator holds the wire with one hand when lapping the lead wire and the wire. The lead wire is held in one hand, and the lead wire and the wire are not reliably fixed during lapping. If the insulating glove is damaged during the operation, it is easy to cause the person to be strung into the circuit during the lead wire lapping process, resulting in electric shock injury. This method is extremely dangerous. There is a large risk of operation, and ther...

[0002] 10kV live connection and branch line lead wire work is a simple live work project, which is usually completed by one person. However, during a long period of operation, it was found that the following disadvantages existed in the previous operation method: 1) The operator holds the wire with one hand when lapping the lead wire and the wire. The lead wire is held in one hand, and the lead wire and the wire are not reliably fixed during lapping. If the insulating glove is damaged during the operation, it is easy to cause the person to be strung into the circuit during the lead wire lapping process, resulting in electric shock injury. This method is extremely dangerous. There is a large risk of operation, and there are also common habitual violations; 2) When the operator overlaps the lead wire and the wire, he must first control the lead wire holder to fix the lead wire, and then perform the lead wire and wire overlap; during this operation, the operator is difficult to operate, High labor intensity; 3) The current parallel hook clamp structure is easy to cause wire jamming or lead wire breakage during installation, especially the spring pad iron must be removed when the large-diameter wire is connected, because the spring pad iron It is very small, and it will bring great inconvenience to live workers when it is removed, so it is not suitable for live work
