LH100 substation intelligent comprehensive dehumidification system Introduction:
The LH100 substation intelligent comprehensive dehumidification system adopts a digital temperature and humidity transmitter array to monitor the average temperature and humidity inside the distribution room, cable trench, and outdoor. Based on this, the algorithm recommended by the World Meteorological Organization and the national military standard GJB1172.1 is used to calculate the air moisture content (water vapor partial pressure) and dew point temperature. The above basic data and calculation data are the basis for the power distribution and control unit to control various execution equipment (including dehumidifiers, cable trench fans, cabinet top and busbar bridge fans, ventilation fans or accident fans, electric windows, etc.). When humidity, temperature, water vapor partial pressure, etc. reach the upper limit of the set value, it will start
Execute equipment in the corresponding area; If it is below the lower limit of the set value, stop the corresponding execution equipment in the area; Technical parameters:
