Description

变电站是电力系统中对电能的电压和电流进行变换、集中和分配的场所，是联系发电厂与电力用户的纽带，担负着电压变换和电能分配的重要任务。如果变电所发生雷击事故，会给国家和人民造成巨大的损失。所以变电所的防雷是不可忽视的问题。目前，架设避雷针是变电所防直击雷的常用措施，避雷针是防护电气设备、建筑物不受直接雷击的雷电接收器，其作用是把雷电吸引到避雷针身上并安全地将雷电流引入大地中，从而起到保护设备效果。然而长时间使用后，避雷针的接地引下线或接地体会发生腐蚀，严重影响雷电流疏导功能，同时，有些地下管线的铺设也会对接地引下线或接地体产生损伤，影响避雷针的功能。由于接地引下线或接地体埋设于地下，因此在变电站安全检修工作中较难检测其功能是否正常，使得变电站在雷雨天存在极大的安全隐患。The substation is the place where the voltage and current of electric energy are transformed, concentrated and distributed in the power system. If a lightning strike accident occurs in a substation, it will cause huge losses to the country and the people. Therefore, the lightning protection of the substation is a problem that cannot be ignored. At present, erecting lightning rods is a common measure for substations to prevent direct lightning strikes. Lightning rods are lightning receivers that protect electrical equipment and buildings from direct lightning strikes. Its function is to attract lightning to the lightning rod and safely introduce lightning current into the ground. , so as to protect the equipment. However, after a long time of use, the grounding down conductor or grounding body of the lightning rod will be corroded, which will seriously affect the lightning current dredging function. Since the grounding downconductor or grounding body is buried underground, it is difficult to detect whether its function is normal during the safety maintenance work of the substation, which makes the substation a great potential safety hazard in thunderstorm days.
