Special cabinet for fire control

Overview of Fire Pump Control Cabinet:

The fire pump control cabinet is composed of advanced PHR1 intelligent digital motor soft starter as the main control component. A starting control device used for operating two fire pumps and one fire pump as a backup. When the running fire pump malfunctions and shuts down, the backup fire pump will automatically start running to ensure reliable supply of the fire pump. The fire pump control cabinet reduces the impact of starting current on the power grid, lowers the capacity of the self-contained generator, and meets the requirements of power grid fluctuations. Reduce the starting impulse torque of the water pump to ensure reliable and rapid starting of the motor. Reduce the failure rate of motors and water pumps, and extend their service life. Equipped with motor soft stop function, it eliminates water hammer phenomenon when the water pump stops, making it an ideal product for fire pump control.

Electrical principle explanation:

Explanation: 1. Two fire pumps, one in operation and one as backup, will be automatically put into operation immediately when the backup is in use. 2. Two units are mutually backup. 3. Fault self resetting.
