| 用途 Application |
Ⅱ 本系列起動(dòng)器廣泛用于煤礦井下，直接控制三相鼠籠型異步電動(dòng)機(jī)的起動(dòng)、停止或反轉(zhuǎn)、短路、斷相及漏電閉鎖等保護(hù)功能。當(dāng)兩臺(tái)聯(lián)鎖使用時(shí)，能對(duì)雙電源供電的雙局扇起到主、輔機(jī)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(xiǎn)礦井，雙電源供電通風(fēng)、排水、供電系統(tǒng)。
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(dāng)兩臺(tái)切換起動(dòng)器聯(lián)鎖使用時(shí)，將兩臺(tái)起動(dòng)器的切換插件上的鈕子開(kāi)關(guān)分別打在在主、輔機(jī)位置，再由人工起動(dòng)主機(jī)，即投入工作。當(dāng)主機(jī)因停電或因故障停止運(yùn)動(dòng)時(shí)，輔機(jī)能自動(dòng)開(kāi)啟。當(dāng)主機(jī)電源或故障排除后，又自動(dòng)切換至主機(jī)運(yùn)行，輔機(jī)停止，并能自動(dòng)閉鎖輔機(jī)，使其不能起動(dòng)，主輔機(jī)自動(dòng)切換時(shí)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 |
