6) AIR COND RLY Air Conditioner Relay 空调继电器补充资料:鼓风机 分子式:CAS号:性质:是气体输送机械的一种,它的排压常为500～105Pa,排压更高的叫压缩机,排压低于此下限的叫排风机。鼓风机不用考虑由于气体压缩而产生的升温和冷却问题。鼓风机中以透平鼓风机和罗茨鼓风机为其代表。透平鼓风机的风量大,但...
空气开关与漏电开关共性:都是开关。 空气开关与漏电开关差别:空气开关是发生短路事故或故障才动作跳闸,而漏电保护开关是人身发生触电时才动作跳闸;空气开关容量可大可小,而漏电保护开关容量不易做大,一般单相居多。 空气开关与漏电开关原理不一样,结构更不一样,绝对不能替代。
