Study on power frequency voltage withstand test simulation and test period improvement of insulating gloves
With the rapid development of live working,insulation gloves are used more and more frequently,but in the power frequency withstand voltage test of insulating gloves,the upper wrist of the glove is prone to insulation damage.In this paper,a simulation model of power frequency voltage resistance test of insulating gloves was established to analyze the water conductivity,the size and position of electrode,the wetting degree of glove inner wall,the test interval and other factors during the test.The results show that when the inner wall of the glove is wet,the uneven degree of electric field increases and the glove is more prone to flashover along the surface.In addition,under the condition of higher water conductivity,the electrode size and position have little influence on the experiment.Finally,an improved method of replacing cylindrical electrode with spherical electrode is proposed to ensure the drying of the inner wall of gloves in the experiment.The test cycle is improved to be dynamic cycle of glove insulation state based on fuzzy comprehensive evaluation.
