不管是室内还是室外的电气设备,使用一定时间后在其表面均不同程度地沉积一些污垢。遇上潮湿天气,这些污垢很容易形成电的良导体,导致电气设备的绝缘电阻下降,严重时发生“电晕”燃损等不良现象,甚至引起闪络、短路等电力故障;当污垢中含有酸或碱等化学物质时,还会腐蚀设备,影响设备的使用效果和寿命。为消除这些隐患,过去一般用手工擦拭的方法去清除污垢。即费力费时,又要停电后才能作业,手触及不到
Whether it is indoor or outdoor electrical equipment, after a certain period of time, some dirt is deposited on the surface to varying degrees. In the event of wet weather, these dirt can easily form good conductors of electricity, resulting in a decrease in the insulation resistance of electrical equipment. In severe cases, there are “corona” burns and other undesirable phenomena, and even cause power failures such as flashovers and short circuits; when the dirt contains Chemicals such as acids or alkalis can also corrode equipment, affecting the effectiveness and longevity of the equipment. In order to eliminate these hidden dangers, in the past, it was generally wiped off by hand. It is laborious and time-consuming, but it is also necessary to operate after a power outage.
