Research on the Harm and the Measure of Using Electricity Earth Fault in Chemical Place

故障电流或电压、PE、PEN线接线端子连接不实等低压配电系统的电气线路和设备的接地故障会诱发电气火灾、经济和财产损失以及人员伤亡事故。文中对低压配电系统的接地形式、接地故障保护的条件、电位联结以及安全检测和管理制度进行了分析。

The fault current or the voltage,low pressure electrical power distribution system's and so on,PE or PEN line binding clamp the connection not reality electrical lines and equipment's earth fault will induce the electrical fire,the economy and the property damage as well as the personnel casualty accident.To the low pressure electrical power distribution system's earth form,the earth fault protection's condition,the electric potential joint as well as the safe examination and the control system have carried on the analysis.
