如電扇、手電鉆、鼓風(fēng)機(jī)、洗衣機(jī)、電冰箱內(nèi)的單相220V電機(jī)的用電負(fù)荷,計(jì)算式為I=8P式中I---單相異步電動機(jī)的額定電流(A)P---電動機(jī)的功率(KW)星接和角接都是P=1.732*U*I*功率因數(shù)星接時(shí)線電壓=1.732相電壓,線電流=相電流。

高壓斷路器的合閘時(shí)間是指斷路器從接到合閘指令(即合閘線圈加上電壓)起到斷路器三相主觸頭均為止所需要的時(shí)間。電力系統(tǒng)對合閘時(shí)間要求不太嚴(yán)格,一般合閘時(shí)間都大于分閘時(shí)間,但希望。高壓斷路器的分、合閘不同期時(shí)間是指斷路器各相間或同相各斷口間分、合閘的時(shí)間差。
