轨道车辆电气柜防结露设计分析

我国幅员辽阔,南北温度差异很大,温度范围可达-40℃~40℃,尤其是冬季,在东北极端低温可达-45℃,为满足乘客乘坐舒适,车内温度始终需保持在23℃左右,由于车内外温差巨大,有时会导致车内某些部位结露,形成冷凝水,对车辆造成损坏,尤其是电气柜内,将给车辆电气控制及行车安装带来极大隐患。

China is a vast country, The north-south temperature is very different, the temperature range can be from -40 ℃ to 40 ℃ , especially in winter, in the northeast of china,the extreme low temperature can reach to -45 ℃, in order to meet passenger comfort, the temperature inside the car always needs to keep 23 ℃ or so, because the difference of temperature between inside and outside is huge, sometimes condensates into dew on surfaces of some cabinets, damages to the vehicle, especially in electric cabinet, it will take harm to the driving safety.
