Rolling-type insulation detection device

Abstract

The invention relates to the field of electrical error detection devices,in particular to a rolling-type insulation detection device. The device includes roller electrodes,insulating side plates and an insulating handle,the two roller electrodes on the front and rear sides are rotatably fixed between the two parallel insulating side plates,the insulating handle is of a hollow structure and fixed to the middles of the insulating side plates,and a wire penetrates through the insulating handle and achieves electric conduction with the roller electrodes. The rolling-type insulation detection device breaks through the limitation that insulating rods and insulating ropes can only achieve spot measurement; by adopting a rolling detection method,complete detection of a surface insulation resistorcan be achieved,and not only is the detection efficiency improved,the reliability of a detection result is improved,but also zero damage of insulating tools can be achieved.

Description

technical field [0001] The invention relates to the field of detection devices for electrical faults, in particular to a rolling insulation detection device. Background technique [0002] Before live work, it is necessary to perform insulation testing on the insulating tools used. The tools that need to be tested include insulating rods, insulating ropes, etc. At present, there is no electrode capable of detecting the full length of insulating rods and insulating ropes. [0003] The currently used insulation detection device can only perform point measurement, usually using a point measurement insulation detection electrode, which is a metal electrode with a width of two centimeters and a gap of two centimeters between the poles. In order to prevent the insulated electrodes from scratching the detected tool during use, the sliding method cannot be used to detect the tool, and only the method of point measurement can be used, which leads to the fact that the entire length of...

AI Technical Summary

Problems solved by technology

In order to prevent the insulated electrodes from scratching the detected tool during use, the sliding method cannot be used to detect the tool, and only the method of point measurement can be used, which leads to the fact that the entire length of the detected tool cannot be covered during the detection, but can only be selected by sampling. point to detect

This detection method cannot guarantee timely detection of insulation defects of tools and appliances

[0004] In practical applications, insulating rods and insulating ropes are often only partially insulated. Since they can only be detected by point measurement, even if the number of point measurements is large, it is difficult to accurately find the location of insulation failure. great security risk
