摘要

"五防"是高压柜中为保证电力电网安全、可靠运行、确保设备和人身安全、防止误操作的联锁功能。在工作实践中

经常遇到有的变配电工程中高压柜的"五防"功能不是很完善

有的甚至存在着很大的安全隐患。为了避免这些带有安全隐患的高压柜投入到供电运行中

笔者对高压柜中一些难解决及易忽视的"五防"问题进行分析

提出解决办法。

Abstract

"Five prevention" is an interlocking function which in order to ensure the power grid safety and reliable operation

to ensure the equipments and personal safety

prevent misoperation. In practice

we often encounter some cases that "five prevention" function in high voltage switchgear is not perfect

and some even exist great security hidden danger. In order to avoid the high voltage switchgear with potential safety hazard are taken into the power supply operation

those "five prevention" problems

which hard to solve and neglect

in high voltage switchgear are analyzed

and solutions are put forward in this paper.
