摘要
开关柜内凝露会产生爬闪、闪络等电气设备运行的危害,因此,依据凝露机理,运用马格拉斯近似方法,探究开关柜内加热器常开、80％ RH和露点3种运行状态,以及各自的耗电量,并就此通过比较计算和分析出目前常开运行状态相比80％ RH和露点两种运行状态的电能浪费量、Co2排放超出量.开关柜内加热器露点运行状态的使用可以节约大量的电能和减少Co2排放,具有很强的现实意义和推广价值.
Abstract
The condensation in HV switchgear may bring about hazards to electrical equipment,such as crawl flash and flashover.Therefore,based on the condensation mechanism and using the Magnus-Tetens approximation method,this paper researches three running states (normally opened heater in the switchgear,80％ RH and dew point) and their respective power consumption.Through calculation and comparison in each state,the analysis indicates that the level of energy waste and CO2 emission of normally opened heater surpasses the other two operating states.Thus,more energy can be saved and more CO2 emissions are reduced when cabinet heater works under dew point condition.This research result has strong practical significance and promotional value.
