摘要(Abstract)：

对一起35kV三星形接线方式电容器组电容量测量异常情况进行分析,指出对现场接线复杂、电容器数量较多的电容器组测量电容量时,应充分理解电容器组的接线方式、保护方式及数字电容表的测量原理,防止测量时带入其他支路的等效电容,并结合实例给出处理办法,解决了测量时容易出现的数据异常问题,有效提高了该类型接线方式下电容器组电容量试验数据的准确性及电容量测量工作的效率。
In this paper, an abnormality case of capacitance measurement of 35 kV voltage grade capacitor group in three stars style connection mode is analyzed. The paper indicates that the connection mode and protection mode of capacitor group as well as the measurement principle of digital capacitance meter must be fully comprehended during capacitance measurement of capacitor group with complex connection mode and multiple capacitors so as not to bring other equivalent capacitors from other branch circuits. Besides, the paper presents a solution in accordance to practical cases to eliminate data abnormity that frequently occurs in the measurement and improve the data accuracy of capacitance test of capacitor group under the connection mode as well as efficiency of capacitance measurement.
