电力电容器维护和运行管理

Maintenance and Operation Management of Power Capacitor

电能在当今社会已经成为不可或缺的一种能源,随着经济社会的高速发展,用电负荷持续增加,电力供应的强度逐渐加大,因此必须继续进行无功功率补偿的工作。当电容器被用作容性功率负荷的装置进行无功功率补偿时,可以增加供电容量,加大有功功率的数值,最为优越的是他较低的成本,和安装使用的便捷,因此被电力系统广泛使用。然而,电容器的无功功率和电压负相关,并受到电压波动的严重影响。对于整个电力系统来说,系统中有许多电气设备,它们的正常运行必须需要消耗一部分电能,而电容器的无功补偿就是把部分电能进行转化,转化成其他形式的能,用以维持电气设备的正常运行。

Electric energy has become an indispensable energy in today's society. With the rapid development of economy and society, the load of electricity continues to increase, and the intensity of power supply increases gradually, so it is necessary to continue the work of reactive power compensation. When capacitors are used as capacitive power load devices for reactive power compensation, the power supply capacity can be increased and the value of active power can be increased. The most superior thing is its low cost and convenient installation and use, so it is widely used in power systems. However, the reactive power of capacitors is negatively correlated with voltage, and is seriously affected by voltage fluctuations. For the entire power system, the system There are many electrical equipment, and their normal operation must consume a portion of the electrical energy, and the reactive power compensation of the capacitor is to convert some of the electrical energy into other forms of energy to maintain the normal operation of the electrical equipment.
