Power control cabinet manufacturers tell you why the fire pump should be equipped with a dual power control cabinet?
In the automatic control system of fire-fighting electrical equipment, the fire pump automatic inspection control cabinet and dual-power control cabinet are indispensable equipment for the automatic control system of fire-fighting electrical equipment. The fire pump is to be equipped with a dual power supply control cabinet.

From its name, we can know that the important electronic components in the cabinet are "dual power switching power switch", which means that it is controlled by a microprocessor and automatically switches the load circuit from one power supply to the other. Switching appliances for another power supply. In fire-fighting equipment, when the power supply is turned off due to various reasons, and the power supply cannot be restored in a short time, it is necessary to use a backup power supply as much as possible. The dual power supply control cabinet is composed of the main switching power supply and the backup power supply equipment, and automatically switches between the main power supply and the backup power supply to ensure the efficiency and continuity of power supply.
When a fire occurs, the main power supply is affected. At this time, the dual power supply control cabinet that has been in the automatic state cuts off the circuit breakers for the main power supply, and then switches to the backup power supply to turn on the backup power supply. When the diesel generator operates normally , sequentially close the diesel generator gas leakage protector and each circuit breaker in the standby power control box; close each backup power circuit breaker in the switching power supply switching box one by one, and switch on each load; within the standby power operation period, the worker Do not leave the diesel generator set, and immediately adjust the working standard voltage, frequency, etc. according to the change of the load, and handle it properly if any abnormality is found. Power control cabinet manufacturers think it is conceivable that dual power control cabinets are very important.
