低压电网中的单相负载及其对电网运行特性的影响

THE SINGLE-PHASE LOAD OF LOW VOLTAGE ELECTRIC NETWORK

针对低压电网中常见的线路末端电压过低及网络损耗过大等现象,本文比 较了三相负载和单相负载的运行特性,分析计算表明单相负载的大量接入 是造成低压电网不经济、不安全现象的主要因素.

To the common phenomenon of lower voltage drop in the end circuit and excessive power loss in the low - voltage electric network, this paper has compared the characteristic of single - phase with three - phase load, also this paper has elucidated that single - phase load excessive connecting into network is main factor to make above - mentioned uneconomical and unsafe phenomena through analyzing and calculating.
