采煤机的鼠笼型感应电动机允许起动电流的大小条件:起动器动力触点的电气耐磨性,是以起动器的实际运转方式、电动机启动条件、采煤机截割机构的构造为转移的;采区电网两相短路电流的允许值和保证过保护装置有足够灵敏度的过保护继电器的整定值;保证电动机具有足够的工作稳定性的电动机端电压波动值和其他用户用电量。
Squirrel-cage induction motor shearer induction motor allows the size of the starting current conditions: Starter power contacts electrical wear resistance is based on the actual operation of the starter, the motor starting conditions, the structure of the shearer cutting mechanism for the transfer The allowable value of the two-phase short-circuit current in the mining area and the setting value of the over-protection relay which ensures the sufficient sensitivity of the protection device; the fluctuation value of the motor terminal voltage which ensures the sufficient work stability of the motor and the power consumption of other users.
