矿用隔爆兼本质安全型六回路真空组合开关(简称组合开关)具有合适的检测电压值,漏电闭锁性能良好,有较好的选择性短路保护性能,保护与控制系统采用PLC控制系统,对设备的整个供电线路进行检测监控,并完成漏电,过载、短路、断相、风电、瓦斯闭锁等保护功能。还可以进行远距离操作,适合于具有爆炸性危险气体(甲烷)和煤尘的矿井中,可以单独使用,也可以与干式变压器和高压真空开关配套使用(整体简称为矿用隔爆型移动变电站)。
Mine flameproof and intrinsically safe six-circuit vacuum combination switch (referred to as the combination switch) with the appropriate detection voltage value, good leakage blocking performance, better selectivity of short-circuit protection, protection and control system using PLC control system, the right Equipment, the entire power supply line detection monitoring, and complete leakage, overload, short circuit, phase failure, wind power, gas lock and other protection. It can also be used for long-distance operation. It is suitable for mines with explosive hazardous gas (methane) and coal dust. It can be used alone or in combination with dry-type transformers and high-voltage vacuum switches (collectively referred to as Mine Flameproof Mobile Substation ).
