中性点不接地系统PT探讨

Discussion on PT of Neutral Point Non Earthing System

中性点不接地系统(Ungrounded Neutral System,简称UNS)是一种用于电力系统的电气接地方式,其在中性点不与地相连,而是通过电抗器与地隔离,从而实现电气隔离保护。文章将重点探讨UNS的原理及其在铜业方面的应用,分析其优缺点及在实际工程中的注意事项。

Ungrounded Neutral System(UNS)is a kind of electrical grounding mode used in power system.It is not connected to the ground at the neutral point,but isolated from the ground through reactor,so as to achieve galvanic isolation protection.This article will focus on exploring the principle of UNS and its application in the copper industry,analyzing its advantages and disadvantages,as well as precautions in practical engineering.
