technical field [0001] The invention relates to an insulation withstand voltage detection device of a power tool, in particular to a section insulation rope withstand voltage test device. Background technique [0002] Insulating rope is a necessary safety tool for live workers. In order to ensure good insulation performance of the insulating rope, electrical tests must be carried out on it every year to check its insulation performance. The segmental withstand voltage (inspection test) of the insulating rope is to inspect the rope at a withstand voltage of 75kV per 300mm for 1 minute.

AI Technical Summary

Problems solved by technology

At present, since there is no dedicated insulating rope test platform, the main problems in the insulating rope test work are as follows:

[0003] 1. Insulation rope section test generally uses both ends to fix the brackets, and then fixes the insulation rope horizontally by winding. The horizontally fixed insulation rope must keep a certain safe distance from the ground to meet the insulation of the pressure end of the insulation rope to the ground. Requirements, the site generally uses fixed brackets or other solid objects that can be wound around the insulating rope to fix the winding insulating rope horizontally. Since there is no uniform specification for fixing the insulating rope, the method of horizontally fixing the insulating rope is confusing during the test work.

During the test, the insulating rope is pressurized and grounded every 300mm, that is, the insulating rope must be led to the test transformer and grounded every 300mm, and the test wiring is messy and cumbersome.

[0004] 2. During the test, copper wires should be used to wind each winding insulating rope according to the pressure end and grounding end of each 300mm to realize the conduction with the insulating rope, especially the winding work of the insulating rope is cumbersome and the work efficiency is low

During the segmental withstand voltage test of the insulating rope, the withstand voltage test must be carried out according to the specified length of 300mm according to the regulations. Generally, a meter ruler is used on site to measure the winding and test length of the insulating rope, which is time-consuming and laborious.
