地面变电站高压供电设备安全问题及对策

Security Issues and Countermeasures of High-voltage Power Supply Equipment in Ground Substation

为了满足人们的用电需求,应当对现有的供电系统进行不断完善。来自电网的电能需要经过变电站的处理,才能变成人们日常可以应用的电能,因而变电站高压电气设备维修工作就尤其重要。高压供电设备结构复杂,一旦发生故障,必然会对电网运行造成一定的影响,甚至造成区域停电。本文首先简要分析了高压电气设备状态检修的特点以及主要的雷击威胁,之后对地面变电站高压设备保护策略进行简要分析。

In order to meet people’s demand for electricity,the existing power supply system should be continuously improved.The electric energy from the power grid needs to be processed by the substation before it can become the electric energy that people can apply daily,so the maintenance of high-voltage electrical equipment in the substation is particularly important.The structure of high-voltage power supply equipment is complex,and once it fails,it will inevitably affect the operation of power grid and even cause regional power failure.This paper first briefly analyzes the characteristics of condition-based maintenance of high-voltage electrical equipment and the main lightning threats,and then briefly analyzes the protection strategies of high-voltage equipment in ground substations.
