Intelligent integrated dehumidification system in LH100 substation
Basic technical principles:Intelligent integrated dehumidification system in LH100 substation adopts digital transmitter array of temperature and humidity to monitor the indoor, cable trench and outdoor average temperature and the humidity of the distribution room. Based on the data, air moisture content ( water vapor partial pressure ) and dew point temperature are calculated by the algorithm recommended by the World Meteorological Organization and the national military standard GJB1172.1. The above-mentioned basic data and calculation data are the basis for the power distribution and control unit to control each execution equipment ( including dehumidifier, cable trench fan, cabinet top and bus bridge fan, ventilation fan or accident fan, electric window, etc. ).According to its internal core control strategy, the power distribution and control unit control the starting, stopping or opening and closing of each executing equipment, and add a rapid cooling criterion as an additional in...
