Introduction of the characteristics and working principle of the fire automatic inspection cabinet

Time2019/3/18AuthoradminClick 225
The digital intelligent fire inspection control cabinet (hereinafter referred to as the fire inspection cabinet) is one of the fire equipment that must be equipped with fire equipment. Its equipment features are as follows:

(1) The low-speed inspection does not pressurize the pipe network system, can achieve the moisture of the motor, prevent the pump from rusting and rust.

(2) Electrical inspection content: electrical main circuit monitoring, power supply voltage, current, phase loss, insulation resistance, withstand voltage, etc.

(3) Equipment performance: 1 electrical main circuit detection; 2 pump automatic low-speed no-voltage patrol inspection; 3 patrol inspection received fire control room command instantaneously switch to power frequency circuit; 4 running image display; 5 fault content display; 6 fault information storage; 7 fault alarm, information printing; 8 reserved building monitoring interface; 9RS485 communication interface; 10 when the fire equipment fails, the relevant personnel will be notified by phone or SMS.



The working principle of the fire patrol cabinet is as follows:

In the non-fire state, the fire automatic inspection cabinet can perform automatic inspection operation on the fire pump. The automatic inspection cycle is optional from several hours to hundreds of hours. The cycle clock automatically starts the inspection program and has manual inspection function. During the inspection, the fire automatic inspection cabinet will check the main circuit of the fire control cabinet and confirm that it is normal. The fire pump will be driven one by one to make it run at low speed. At this time, the driving power is very small, about 1% of the rated power of the pump motor. Therefore, energy saving is remarkable. Due to the low speed, the water supply network will not be pressurized. If the fire operation command is received during the inspection, the control device will immediately interrupt the inspection operation, and the control device will drive the fire pump to the fire command operation at the power frequency. A new inspection operation process is started only when the next inspection cycle is reached and no fire incident occurs. During the inspection, if the pump fails, a fault alarm message will be given. When an input overvoltage, undervoltage, phase loss, output overcurrent, or short circuit occurs, the fire automatic inspection cabinet will send an alarm message to the fire center. The result of this automatic inspection ensures that the fire pump will not produce rust and rust. The fire water supply equipment "fosters a thousand days, using soldiers for a while" becomes a reality. The device also has the automatic exchange function of the main and standby pumps, that is, when the main pump fails, the standby pump is automatically put into operation; the main and standby power supply automatic mutual investment function, that is, when the main power failure occurs, the standby power supply is automatically input. The fire automatic inspection control cabinet provides functions such as data remote transmission, image monitoring, fault alarm, and information printing for all the above functions.
