防爆电度表箱

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.

主要特征

装有DSS(X)666型电子式电能表,该表是具有国际先进水平的电能仪表,该表能实现分时计量,设定日自动转存数据,红外遥控编程,手持终端或PC机编程及抄表,LCD显示等功能。该表可进行4种费率,10个时段、2个时区设置,并具有电能测试、脉冲输出功能。

Features

The watt-hour meter box is composed of the explosion-Features proof joint box and shell. It’s equipped with the three-phase three-wire active (reactive) watt-hour meter, current transformer and voltage transformer and so on.
