| 摘 要： | 35 kV级箱式并联电容器的内部故障采用电压差动保护,为满足保护整定的要求,这类电容器上下段电容的制造偏差须加以限制,但这种限值应与集合式并联电容器的限值有所区别.文章根据箱式并联电容器的结构特点,讨论了这类产品的保护整定原则,通过对不同规格典型产品的计算分析,归纳出确定这类电容器上下段电容制造偏差限值的方法.

| Abstract: | The voltage differential protection is usually used for the protection of 35 kV cabinet shunt capacitors for the internal faults.It is necessary to limit the manufacturing deviations of capacitance between up and down segments of these capacitors for satisfying the requirement of protection setting,but such limited deviation values shall be different from that of assembling shunt capacitors.In this paper,the setting principle of the voltage differential protection according to the structures and characteris... |
