Cooling water power supply system for single crystal furnace

The utility model belongs to the technical field of cooling water, and provides a cooling water power supply system of a single crystal furnace. The cooling water power supply system of the single crystal furnace comprises a circuit breaker connected with a mains supply; and the frequency converter is connected with the circuit breaker and is also connected with the water pump motor. By adopting the technical scheme in the embodiment of the utility model, the current is changed through the frequency converter, so that the current is started from zero when the motor is started, the damage to a power grid caused by direct impact of hard start of the motor is reduced, the motor reaches a more stable start and operation state, equipment and lines thereof are protected, and the service life of the motor is prolonged. And compared with the current regulation and control of the voltage and the current by using a soft starter, the energy consumption in the starting of the motor is saved, and a better energy-saving ef
