软启动器实则降压启动器,,,,一般是输出三相,,电压由低变高的电子设备..
Soft starter actually step-down starter, which is usually output three-phase, the voltage from low to high electronic equipment
补充知识:
Supplementary knowledge:
电机有星接和角接两种,,,,,,星接是降压接法用于大功率电机启动时不伤害电网的一种小电流启动,电机运转力矩小...
There are two kinds of motors: star connection and angle connection. The star connection is the step-down connection method, which is used to start a small current without damaging the power grid when the high power motor is started, and the motor has a small torque...
角接是电机正常运行时的接法,,运转力矩大,电流也大所以一般大功率电机是不直接角接启动.
Angle connection is the method of normal operation of motor, the running torque is large, the current is large, and so,,,, and so on, so the general high-power motor is not directly angle start
既然软启动器是电压由低变高输出三相的设备,,,那么电机当然要接角接....这样可以获得大的启动力矩,,,,,
Since soft starter is a device that outputs three-phase voltage from low to high, then the motor must be connected with angle. Thus, a large starting torque can be obtained,,,,,
