Problems solved by technology

All the above tests need to be carried out in insulating liquid. After the test, the insulating tool is stained with insulating liquid and cannot be used for live work immediately.
Another method is to use a shaking meter to measure the resistance on site, which requires two workers to work together. This method cannot fully detect insulating tools, and the detection efficiency is low

Description

technical field [0001] The invention relates to the field of electric tool detection, in particular to a defect detection device for an insulating tool for live working. Background technique [0002] At present, there are many types of insulating tools and safety protection equipment used in live work, and the structure is very different. Their insulation performance is directly related to the safety of workers and equipment. Therefore, the management and use of insulation tools and safety protection equipment must comply with the "State Grid Corporation of China According to the requirements of the relevant regulations in the Electric Power Safety Work Regulations (Circuit Part), strictly abide by the regulations in the safety regulations and conduct regular tests to find out the existing defects and hidden dangers in time. [0003] Live working safety protection equipment includes insulation protection equipment, insulation masking tools and shielding equipment. Long-term ...
