Description

A drainage wire fixing device for live work of distribution lines

technical field

Background technique

In recent years, with social and economic development, power customers have higher and higher requirements for continuous and stable power supply, and live work on distribution lines has become an effective means to ensure the reliability of power supply. In order to control the drainage line and avoid faults such as interphase short-circuit or grounding, the grounding bodies such as poles, towers or cross-arms are generally carried out first. After insulating and shielding, the drainage wire is fixed with an insulating rope, so as to ensure a safe distance between the drainage wire and the main wire, and at the same time, the drainage wire can be fixed. When using insulated ropes to fix the drainage wire, the drainage wire needs to be forcibly bent and then hung on the insulated wire. Not only a large number of shielding appliances are required in the operation, but also the safety factor is low and the working intensity is high. The forced bending of the drainage wire may also affect the drainage wire. In addition, if the drainage wire is only hung on the insulated wire, the drainage wire is easy to fall off from the insulated wire, which greatly affects the safety of live work. When carrying out live work, the operator will be inconvenient because of wearing insulating protective equipment, and the operator cannot flexibly and quickly complete the action of tying and fixing the drainage wire with insulating rope during the operation. The operation is difficult and dangerous. high.
