Problems solved by technology

[0004] Because the line is charged, the human body should keep a safe distance of more than 0.4 meters from the live line during operation. If the fixing device is directly operated by hand, this safe distance will not be satisfied; The hoop is fixed on the pole, but this method has disadvantages such as shaking of the insulating pole due to too long and inconvenient carrying of tools, which cannot meet the purpose of fast and safe replacement of insulators

Abstract

The invention relates to a device for replacing an insulator in an alive state. The device is characterized by comprising a support, a fixed pulley assembly, and a fixing assembly. The fixed pulley assembly is fixed to one end of the support. The fixing assembly is in sliding connection with the support. The support is connected with a cross arm via the fixing assembly. When an insulator is replaced, the support is installed on the cross arm through the fixing assembly and a faulted cable is hoisted by the fixed pulley assembly. As a result, the insulator is replaced in the alive state. Compared with a product in the prior art, the device is safe and reliable, and easy to carry, satisfies a purpose of quickly replacing the insulator, enhances power supply reliability, increases power sales amount, improves industrial service quality, a guarantee clients uninterrupted power supply, has very positive significance to increase in power supply reliability and power sales amount, and increases social benefit and economic benefit.

Description

technical field [0001] The invention relates to the field of power supply and utilization, in particular to a device for exchanging insulators with electricity. Background technique [0002] With the increase of the length of 10KV distribution lines, more and more line insulators are used. Under the influence of smog and thunderstorms, the number of serious insulator pollution and insulator breakdown accidents on line insulators is also on the rise. And because the replacement of line insulators in a power outage involves a wide range of power outages, which seriously affects the reliability of power supply, the damage of line insulators has become one of the main sources that seriously threaten the safe operation of distribution network lines. [0003] Today, when the reliability of power supply is becoming more and more important, live working as one of the important means to improve the reliability of power supply has been paid more and more attention. Non-stop maintenanc...
