| 用途 Application |
Ⅱ 本系列起动器广泛用于煤矿井下，直接控制三相鼠笼型异步电动机的起动、停止或反转、短路、断相及漏电闭锁等保护功能。当两台联锁使用时，能对双电源供电的双局扇起到主、辅机相互切换的功能，保证了工作的可靠性，特别适用于高瓦斯等危险矿井，双电源供电通风、排水、供电系统。
Ⅱ This series starter widely used in the coal mine,and direct control starting, stop and reversion of three-phase squierrel cage type asynchronous motor ,possesses protection functions such as over load,short circuit,loss of phase and electrical leakage locking,etc.When tow sets interlock used,canrealize the mutual switch function for the main engine and auxiliary engine of the double portable fan ,which is double power supplied.Thus assure the work reliability,especially applicable for mine with high dangerous gas and draughty,water disvharge and power supply systems with double power supplied. |

Ⅱ 当两台切换起动器联锁使用时，将两台起动器的切换插件上的钮子开关分别打在在主、辅机位置，再由人工起动主机，即投入工作。当主机因停电或因故障停止运动时，辅机能自动开启。当主机电源或故障排除后，又自动切换至主机运行，辅机停止，并能自动闭锁辅机，使其不能起动，主辅机自动切换时间<2秒
Ⅱ When two switchable starters interlock used,push the button switches,which are on the switching plug in board of the two starters,to the main engine and auxiliary engine positation separately,then manual start the main engine to start work When the main engine stop working because of fault or power cut,the auxiliary engine can start autimatically.Whenthe poer cut or fault on the main engine eliminated,it will shift to the main engine and work,and the auxiliary engine be in stop and locked automatically.The switching time for main engine and auxiliary engine <2 sec |
