The
system is applied to a dehumidification
monitoring system applied to a
transformer station cable trench. The
system comprises a sensor
assembly, a processor module, a
GSM wireless module and dehumidification equipment, wherein the sensor
assembly comprises a temperature and
humidity sensor, the dehumidification equipment comprises an upper dehumidification
system and a lower dehumidification system, the temperature and
humidity sensor is connected with the processor module through an RS485
communication interface, the processor module is connected with the
GSM wireless module through a
serial port module, the
GSM wireless module is connected with the upper dehumidification system and the lower dehumidification system, the upper dehumidification system is installed in a
transformer station machine room, the lower dehumidification system is installed in a cable trench of the
transformer substation
machine room, the dry air is replaced by the lower dehumidification system in the cabletrench to enter the cable trench,
moisture is discharged into the transformer
station machine room through circulation, the
moisture is compressed into the water through the upper dehumidification system in the transformer station machine room to be discharged out of the room, and the dry air enters the cable trench to be circulated in a reciprocating mode. The system is advantaged in that a
moisture problem of a switch cabinet can be fundamentally solved, and accidents such as condensation
discharge of the switch cabinet, reduction of cable insulation, explosion of the switch cabinet and thelike are effectively avoided.
