摘　　要：电容器是电力系统中常见的电气设备,对电网安全、经济运行具有十分重要的意义。并联电容器主要用于交流电路中补偿感性负荷的无功功率,以提高功率因数,从而提高电压质量,减少线路损耗。在日常使用中,并联电容器由于受到制造质量、过电压、谐波、现场环境、规格不匹配以及日常维护不到位等方面的影响,会发生鼓包漏液,甚至爆炸的情况,给企业的生产、人员安全以及电力系统的正常运行带来很大的威胁。Capacitor is a common electrical equipment in power system,which is of great significance to the safe and economical operation of power grid.Shunt capacitors are mainly used to compensate reactive power of inductive load in AC circuit to improve power factor,thus improving voltage quality and reducing line loss.In everyday use,the parallel capacitor due to manufacturing quality,over voltage,harmonic problems,the environment,the specification does not match,the influence of the daily maintenance is not in place,etc,will cause a bulge discharge of the capacitor,explosion,even to the enterprise’s production and safety of personnel,and the normal operation of the power system brings great threat.
