| 用途 Application |
Ⅱ 本系列起動器廣泛用于煤礦井下，直接控制三相鼠籠型異步電動機的起動、停止或反轉、短路、斷相及漏電閉鎖等保護功能。當兩臺聯鎖使用時，能對雙電源供電的雙局扇起到主、輔機相互切換的功能，保證了工作的可靠性，特別適用于高瓦斯等危險礦井，雙電源供電通風、排水、供電系統。
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 當兩臺切換起動器聯鎖使用時，將兩臺起動器的切換插件上的鈕子開關分別打在在主、輔機位置，再由人工起動主機，即投入工作。當主機因停電或因故障停止運動時，輔機能自動開啟。當主機電源或故障排除后，又自動切換至主機運行，輔機停止，并能自動閉鎖輔機，使其不能起動，主輔機自動切換時間<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 |
