摘　　要：电气设备的绝缘长期运行中会受到受到电场、热效应、机械应力、化学腐蚀以及环境条件等因素的影响,其绝缘品质将逐渐劣化,极可能导致绝缘系统的破坏,因此一般在高电压试验室中模拟工频交流电压、冲击高电压或直流电压来检验电气设备绝缘的耐压能力。基于此,介绍了高频高电压试验与脉冲高电压试验,最后又分析了高电压试验中的安全防护措施。The insulation of the electrical equipment will be long term operation by electric field, heating, mechanical stress, chemical corrosion and the environmental condition the influence of factors, its insulation quality will gradually degradation, most probably lead to the destruction of the insulation system, so general in high voltage in simulated labo- ratory work frequency voltage, impact of high voltage or de voltage electrical equipment to test the pressure - resistance insulation. Based on this, this paper introduces the high frequency and high voltage and pulse test of high voltage test, then analyzes the trials of high voltage safety protection measures.
