摘要
常见的电力电容器都是为了改善电力系统的电压质量和提高输电线路的输电能力,它们在减少系统功率损耗、提高功率因数、降低运行电流、提升电网电压、释放变压器使用裕度等方面有着显著效果。按电压等级可以划分高、低压两部分。虽然它们可以起着不可替代的作用,但是多年的运行经验表明,电力电容器经常性出现各种问题,因此有必要对电力电容器常见的故障分析并处理,文章对实践工作有一定的指导意义。
The common power capacitors are to improve the voltage quality of the power system and improve the transmission capacity of the transmission line.They have a significant effect in reducing the power loss of the system,increasing the power factor,reducing the operating current,increasing the voltage of the power grid,releasing the use margin of the transformer and so on.According to the voltage level can often be divided into high and low voltage two parts.Although they can play an irreplaceable role,many years of operation experience has shown that power capacitors often have a variety of problems,so it is necessary to analyze and deal with the common faults of power capacitors.The article has certain guiding significance to the practical work.
