Low pressure control cabinet control cabinet structure is characterized by the following main points:

1, advanced technology: the use of PLC makes the equipment according to the water supply fire fighting requirements to achieve intelligent constant pressure variable supply volume water supply;

2、Energy-saving: the system can set the pressure on demand, the system automatically adjusts the pump speed the number of pumps running according to the set pressure, so that the equipment operates in an energy-saving state;

3、Stable water supply pressure: the system realizes closed-loop control, which can automatically adjust the difference between the set pressure the system pressure to keep the pressure constant;

4, stable operation: the system is automatically controlled by the frequency converter frequency converter plus intelligent controller, the operation is extremely simple;

5, prolong the life of the motor, pump: each pump are soft start, eliminating the inrush current at startup. Each pump cycle start, gallon cabinet so that the backup pump will be long unused rust wear tear due to frequent use. The fire to realize the regular inspection;

6, perfect protection: short circuit, overcurrent, overvoltage, overheating, overload other protections, pumps run such as applause, automatically stop working alarm output; the system has a self-check, fault judgment, fault memory, fault display, automatically start the standby pump other functions.

7, small flow sleep function: can be equipped with subsidiary small pumps, so that the system runs at night other small flow conditions, automatically shut down the main pump, open the subsidiary small pumps, so as to avoid the waste caused by the opening of high-power pumps;

8, easy to operate function: inverter controller programming setting is convenient simple, easy to master;

9, hand-automatic switching function: manual switch control is available, which can ensure the continuous operation of the equipment;

10, with sub-voltage time-sharing water supply function, more than six periods of time control, the user can set their own, can realize unattended.

High low voltage control cabinet is a kind of combined high low voltage switchgear assembled with standard mold work, the control cabinet is suitable for AC 50-60HZ rated working voltage 660V the following power supply system, used for power generation, power transmission, power distribution, power conversion control of power consumption equipment. The cabinet complies with IEC439-1 “Low-voltage complete sets of switchgear control equipment”, GB7251 “Low-voltage complete sets of switchgear control equipment”, JB/T9961 “Low-voltage withdrawable complete sets of switchgear” other standards.
