摘　　要：探讨一种新的10 k V电容器组差压保护定值的整定方法。从电容器组上、下节电容值之间的偏差出发,结合设备实际维护情况及预试规程中关于电容器组电容值的条文,按照对设备有利的原则,推导出针对不同型式10 k V电容器组差压保护定值的整定公式。最后以某集合式电容器组为实例,验证所给出的差压保护定值整定方法是正确、可行的。A novel setting method of differential pressure protection setting value of 10 kV capacitor bank is discussed. Settingformulas for different types of differential pressure protection setting values in 10 kV capacitor bank are deduced, starting from thedeviation capacitance value between the upper and lower sections of capacitor bank, and combining with actual equipment maintenancesituation and provisions about the capacitance value of capacitor bank in the pre-test procedure, and according to the principle of beinggood for equipment. Finally, an assembling capacitor is taken as an example to testify that the proposed setting method of differentialpressure protection setting value is correct and feasible.
