适用范围及用途

电度表箱主要用于煤矿中或其他周围介质中含有爆炸性气体(甲烷)的工业企业中，供交流50Hz；电流200、400；电压380V、660V的电力系统中计算有功、无功电能之用，但在煤矿中不能用于采掘工作面。
 
Applications
The watt-hour meter box is mainly used to calculate active or reactive electric power energy in the AC power system, with the frequency of 50Hz, current of 200A or 400A, and voltage of 380V or 660V in the coal mine well or other industrial enterprises, with the surrounding medium containing explosive gases (methane). However, it can not be used for the excavating working surface.
