摘要
串补装置电容器组内部电容器元件损坏时,会造成电容器不平衡电流增大,为避免电容器不平衡保护告警或跳闸,有必要对电容器不平衡电流进行测试。本文介绍了串联补偿装置电容器不平衡电流保护的基本原理,分析了影响电容器不平衡电流大小的因素,重点探讨了电容器不平衡电流的调整方法以及测试方法,最后结合实际工作提出了电容器不平衡电流调整及测试工作应注意的问题。
When the internal capacitor element of the capacitor bank of the series compensation device is damaged,the unbalanced current of the capacitor will increase.In order to avoid the alarm or trip of the capacitor unbalanced protection,it is necessary to test the capacitor unbalanced current.In this paper,the basic principle of capacitor unbalanced current protection of series compensation devices is introduced,the factors affecting the capacitor unbalanced current is analyzed,and the adjustment methods and test methods of capacitor unbalanced current are discussed in detail.Finally,the problems that should be paid attention to in the adjustment and test of capacitor unbalanced current are proposed in combination with actual work.
