斜井提升绞车定点限速保护

Protection of Inclined Shaft Hoist Winch by Speed Limitation At Fixed Point

通过对斜井提升绞车电动机转子串入电阻的理论计算和选取,用定点限速方法来实现KJ型斜井提升绞车的限速保护。

This article deals with the theoretical calculation and selection of the connection of resistance into the motor rotor on the inclined shaft hoist winch, and how to protect the KJ inclined shaft hoist winch by the method of speed limitation at a fixed point.
