Working method of breaking the upper lead wire of 10kv live drop-out fuse

Abstract

The invention relates to an operation method for breaking the upper lead wire of a 10kV live-line drop-out fuse, which uses a lead wire insulation fixer to fix the lead wire and the main lead wire, and is suitable for the operation method of using a lead wire clip for overlapping the lead wire; the lead wire insulation fixer is composed of Composed of a pliers body, an insulating handle and a pin shaft; the integrated pliers body and insulating handle are symmetrically fixed together by the pin shaft to form a pincer-shaped structure; the pliers body is provided with wire fixing grooves and lead wire fixing grooves. Compared with the prior art, the beneficial effects of the present invention are as follows: 1) By applying new tools and tools, the live working method is improved, labor intensity is reduced, operation risks are avoided, and habitual illegal operations are eliminated. 2) In actual application, the safety accident rate of the 10kV live wire breaking and dropping top lead wire operation more than 200 times throughout the year is 0, and the safety is high. 3) It is easy to operate and improves working efficiency. It is suitable for the working method of insulating gloves and the working method of insulating poles, reduces the amount of tools used, and improves the reliability of power supply.

Description

technical field [0001] The invention relates to the technical field of breaking wires of drop-out fuses of power distribution lines in power grids, in particular to an operating method for breaking the upper leads of 10kV live fuses. 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 has a great risk of operation, and there are also co...

[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.
