摘　　要：高压并联电容器的性能和使用寿命很大程度取决于他们所处的运行条件。高压并联电容器运行温度对其应用至关重要。本文依托高压并联电容器在线监测系统积累了电容量及壳体温度值数据,并分析了高压并联电容器在运行中电容量与壳体温度的关系,并特别指出:在采用参考电容量的相对变化来评定电容器状态时,应该考虑对实测电容量进行温度修正。The performance and service life of high voltage shunt capacitor, to a large extent, are depended on its operation condition. The operating temperature of high voltage shunt capacitor is very important to its application. In this paper, the data of capacitance and temperature of case is accumulated on the basis of on-line monitoring system of high voltage shunt capacitor, the relation between the capacitance and shell temperature of the capacitor in operation is analyzed. It is pointed out in particular that in case of evaluating capacitor＇s condition with reference of relative variation of capacitance,the temperature correction on the actually measured capacitance should be considered.
