Problems solved by technology
[0002] At present, various reasons in the operation of insulators will cause the insulation level to drop, or even insulation breakdown. The potential difference between the insulators forms a gap spark discharge, which works well, but it requires personnel to enter the electric field for detection. Since the potential difference between the insulator sheets of each voltage level is different, it is necessary to prepare multiple detection tools according to the voltage level. On the one hand, it increases On the other hand, it also increases the enterprise’s investment in tool testing and testing. The most important thing is that once the worker takes the wrong tool, the tool will be damaged during the test, the test result will be wrong, and even an accident will occur. is a known problem with such tools

Description
technical field [0001] The invention relates to an insulator live detection tool. Background technique [0002] At present, various reasons during the operation of insulators will cause the insulation level to drop, or even insulation breakdown, which has always been a problem that plagues power companies. It is known to use sparks to check. The principle of this method is to use the insulator The potential difference between the insulators forms a gap spark discharge, which is very effective, but it requires personnel to enter the electric field for detection. Since the potential difference between the insulator sheets of each voltage level is different, it is necessary to prepare multiple detection tools according to the voltage level. On the one hand, it increases On the other hand, it also increases the enterprise’s investment in tool testing and testing. The most important thing is that once the worker takes the wrong tool, the tool will be damaged during the test, the ...
