　　供水接線供水接線需要用到液位繼電器的2和3這組常開點，當(dāng)水位下降到低時，2和3就會導(dǎo)通水泵開始抽水。當(dāng)水位達到高時，2和3復(fù)位斷開電機停止，所以可以把2和3理解為一組開關(guān)。排水電路排水電路需要用到液位繼電器的3和4這組常閉點，當(dāng)水位排到低時，3和4這組常閉點就會斷開，水泵就會停止排水�！　「邏簲嗦菲鞯暮祥l時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間。電力系統(tǒng)對合閘時間要求不太嚴格，一般合閘時間都大于分閘時間，但希望。高壓斷路器的分、合閘不同期時間是指斷路器各相間或同相各斷口間分、合閘的時間差。
