电容性非线性负载的通电冲击电流

The Electrifying Impulse Current of Capacitive Nonlinear Loads

电容性非线性负载因其特殊的伏安特性,合闸通电瞬间的电压突变,必然产生通电冲击电流。本文结合工程实例,分析民用建筑电容性非线性负载中最常见的计算机、金卤灯负载的通电冲击电流对配电系统的影响,提出相应的配电解决方案。

Because of the special voltammetry of capacitive nonlinear loads, an electrifying mutation voltage will inevitably produce an electrifying impulse current. In this paper, the impact on the distribution system caused by the electrifying impulse current of capacitive nonlinear loads is analyzed with engineering examples, which generally existing in civil buildings such as： computers, metal halide lamps, etc. Then, appropriate solutions for power distribution are proposed.
