Insulation boot withstand voltage test device

Abstract

The invention discloses an insulation boot voltage withstand test device, belonging to the technical field of insulation appliance testing. The device comprises a voltage withstand test component and a grounding conductive connection piece which is connected to the voltage withstand test component. The grounding conductive connection piece is connected to the outside of an insulation boot. A steel wire shoe-pad is laid in the insulation boot. The steel wire of the steel wire shoe-pad is a spiral elastic steel wire with the diameter of 0.03mm to 0.5mm. The specification of the steel wire shoe-pad is larger than that of the standard shoe-pad of a same shoe size. The steel wire shoe-pad is connected to the voltage withstand test component. The insulation boot voltage withstand test device has the advantages of a simple operation, good contact, uniform pressure resistance and time saving.

Description

technical field [0001] The invention belongs to the technical field of insulation product testing, and in particular relates to a voltage-resistant testing device for insulating boots. Background technique [0002] Insulating boots are protective equipment that electric workers must wear. After a period of time, the insulation performance of the insulating boots will change. In order to ensure the safety of the electric workers, it is necessary to conduct a withstand voltage test on the insulating boots regularly to detect the insulation of the insulating boots. Spend. [0003] The insulating boots withstand voltage test needs to test the withstand voltage performance of the insulating boots by means of uniform pressure on the sole. The traditional method is to evenly pressurize the insulating shoes by adding water or iron beads. Adding water to carry out the withstand voltage test is to inject a certain amount of water into the insulating boots first, keep the edge of the...

AI Technical Summary

Problems solved by technology

Adding water to carry out the withstand voltage test is to inject a certain amount of water into the insulating boots first, keep the edge of the boot above the insulating boot dry, clamp the edge of the boot with iron clips, and then hang the insulating boot in a grounded iron water tank. Put it into the insulating boots and then pressurize, but the water in the insulating boots will wet the lining of the insulating shoes. After the test is completed, it will take a long time to dry and cannot be used in time. In order to meet the needs of the work, more Equipped with insulating boots; the method of iron balls is to fill the tested boots with iron beads with a diameter of no more than 4mm and a height of no less than 15mm, weld a piece of copper sheet with a diameter of more than 4mm to the external wire, and bury it in the iron beads as an internal electrode , the high-voltage line is suspended in the air and connected to the inner electrode of the insulating boot, and the outer electrode is water placed in a metal vessel. The tested boot is placed in the metal vessel, and the iron ball is easy to roll and it is difficult to fully and evenly cover all positions of the insulating boot sole, and uniform pressure cannot be achieved. It is inconvenient to put in and take out; there is also a method of spreading iron sand on the soles of the boots, but the iron sand is easy to stick to the inner lining of the boots, and it is not easy to pour it out, making the inner lining of the boots dirty
