| 摘 要： | 额定电压是并联电容器装置中单台电容器的一个重要参数。额定电压选择过低将会导致电容器故障率增加、运行可靠性降低,选择过高则会造成设备利用率低。因此,提出了工程上选择并联电容器额定电压的原则,并推导出并联电容器额定电压的通用计算公式。同时分析了电容器装置参数变化引起的电容器运行电压升高系数,并提出一些实用的判别依据,为电容器装置的设计和运行维护提供参考。

Selection of the Rated Voltage of Shunt Capacitor in Substation |
| |
| Abstract: | Rated voltage is an important parameter of capacitor in shunt capacitor installation.Too low rated voltage will increase the fault rate and decrease the operation reliability,while higher rated voltage will cause the low utilization ratio of resource and equipments.In this article,the selection principle of the rated voltage of shunt capacitor in engineering is introduced,and the calculation formula of the rated voltage of shunt capacitor is derived out by using the circuit theory.At the same time,the incre... |
