Insulating glove withstand voltage test tool and using method

Abstract

The invention relates to an insulating glove withstand voltage test tool, which comprises an insulating glove, a hand model and a hand concave mold; a conductive glove made of conductive cloth is wornon the surface of the hand model, and a test grounding wire is led out of the conductive glove; the internal of the hand concave mold is fixedly covered with conductive cloth, a pressurizing line fortest is led out of the conductive cloth in the hand concave mold, and the hand model is manufactured according to the insulating glove; and the hand concave mold is manufactured according to the insulating glove, the insulating glove comprises an insulating glove body, and the insulating glove body is a five-finger glove or a connected-finger glove made of rubber. The invention further relates toa using method of the insulating glove withstand voltage test tool, and the using method is simple. The glove is prevented from being immersed in water for testing, the testing speed is increased, and the standard of the withstand voltage of each part of the glove is ensured.

Description

technical field [0001] The invention relates to the technical field of electric equipment, in particular to an insulating glove withstand voltage test tool and a use method thereof. Background technique [0002] Insulating gloves need to do periodic withstand voltage tests. The traditional test method is to put the gloves in water, and at the same time add water to the inside of the glove, pressurize the water while grounding in the water for the pressure test. This method has the following disadvantages: 1. The water is pressurized, and the resistivity of tap water is about 1300 ohm / cm. During the test, it is equivalent to introducing resistance and glove insulation to share the test voltage, and the resistance to each part of the glove is different. Therefore, the actual application The test voltage on insulating gloves is subject to error. 2. Since the insulating gloves in the water need to be fixed, and the water inside and outside the gloves needs to be isolated by the...

Problems solved by technology

This method has the following disadvantages: 1. The water is pressurized, and the resistivity of tap water is about 1300 ohm / cm. During the test, it is equivalent to introducing resistance and glove insulation to share the test voltage, and the resistance to each part of the glove is different. Therefore, the actual application There is an error in the test voltage on the insulating glove

2. Since the insulating gloves in the water need to be fixed, and the water inside and outside the gloves needs to be isolated by the gloves, the wrist part of the gloves will not be immersed in the water, and no voltage is applied to this part, so the pressure resistance part of the insulating gloves has not been effectively tested

3. Insulating gloves should be stored in a dry and clean environment. After being pressurized in water, it takes at least a few hours to dry. Water will partially affect the insulation of insulating gloves.
