Soft starter uses a current control loop, can track changes in motor current at any time. By increasing the setting of overload current and inverse time control mode, overload protection function is realized, so that the thyristor is turned off and an alarm signal is generated when the motor is overloaded. At work, the soft starter to detect changes in the three-phase line current at any time, in the event of a cut-off, you can make a lack of protection reaction. Through the soft starter internal thermal relay thyristor heat detector temperature, once the radiator temperature exceeds the allowable value automatically shut off the thyristor, and send an alarm signal. Through the combination of electronic circuits, but also in the system to achieve a variety of other interlock protection. 1, overload protection function: The soft starter introduces a current control loop, thus tracking changes in the status of the motor current at any time. By increasing the setting of overload current and inverse time control mode, overload protection function is realized, so that the thyristor is turned off and an alarm signal is generated when the motor is overloaded. 2, phase loss protection: work, the soft starter to detect changes in the three-phase line current, in the event of a cut-off, you can make a lack of protection reaction. 3, over-temperature protection function: through the soft starter internal thermal relay thyristor heat detector temperature, once the radiator temperature exceeds the allowable value automatically shut off the thyristor, and send a warning signal. plastic hair comb mould,plastic hair comb mold, plastic comb injection mold Yuyao Hongzhou Plastic Technology Co., Ltd. , https://www.hongzhoumoulds.com
