Shanxi soft starter, namely Shanxi soft starter, mainly has the following four protection functions:
1. Overheat protection function: the temperature of the thyristor radiator is detected by the internal thermal relay of the soft starter. Once the radiator temperature exceeds the allowable value, the thyristor will be automatically turned off and an alarm signal will be sent out.
2. Other functions: Through the combination of electronic circuits, other interlocking protections can be realized in the system.
3. Overload protection function: The soft starter introduces a current control loop, so it can track and detect the change of motor current at any time. By increasing the setting of overload current and inverse time control mode, the overload protection function is realized, so that when the motor is overloaded, the thyristor is turned off and an alarm signal is sent out.
4. Open-phase protection function: When working, the soft starter can detect the change of three-phase line current at any time, and once the current is cut off, it can make a open-phase protection response.
