Soft start is achieved by technical means such as buck, compensation or frequency conversionThree-phase asynchronous motorThe smooth starting of mechanical load reduces the impact of starting current on the power grid, so that the power grid and mechanical system can be protected; The output torque meets the requirements of the mechanical system for starting torque, ensuring smooth acceleration, smooth transition, and avoiding the impact of destructive torque.

       The motor soft starter itself is not energy-saving, first, it is not an electrical equipment, but a simple functional product to achieve motor soft starting; Second, it works for a short time and exits after starting.

       butThree-phase asynchronous motorThe application of soft start technology can achieve energy saving of the drag system:

       1Reduce the requirements of motor starting on the power system, power transformer selection can ensure that it always runs in the economic operation area, reduce the power transformer operation loss, thus saving energy.

       2The motor starting problem is solved by the soft starting device to avoid the phenomenon of large horse-drawn trolley

       Soft start principle:

       ①The phase-shift voltage regulation principle of thyristor is used to realize the voltage regulation starting of the motor, which is mainly used for the starting control of the motor, and the starting effect is good but the cost is high.

       ②Fluctuations in the power grid can also affect the conduction of thyristors, especially when there are multiple thyristors in the same power grid. Therefore, the failure rate of thyristor components is higher, because it involves power electronics technology, so the requirements for maintenance technicians are also higher.
