電氣開(kāi)關(guān)柜(鎧裝開(kāi)關(guān)柜 )里的UA表示欠電壓脫扣器,青島gck開(kāi)關(guān)柜(配電開(kāi)關(guān)柜 )而OVP1表示過(guò)電壓脫扣器。青島gck開(kāi)關(guān)柜(雙層開(kāi)關(guān)柜 )所以UA+OVP1是指包含了欠電壓脫扣器以及過(guò)電壓脫扣器的功能。青島10kv高壓開(kāi)關(guān)柜(西門子35KV開(kāi)關(guān)柜 )型號(hào)
欠電壓脫扣器表示當(dāng)電壓下降到額定值的一定比例時(shí),青島10kv高壓開(kāi)關(guān)柜(小型化開(kāi)關(guān)柜 )型號(hào)比如70(百分比)-30(百分比)是,青島10kv高壓開(kāi)關(guān)柜(直流開(kāi)關(guān)柜 )結(jié)構(gòu)脫扣器就會(huì)動(dòng)作,青島10kv高壓開(kāi)關(guān)柜(中低壓開(kāi)關(guān)柜 )柜后放電并帶動(dòng)與其接在一起的斷路器快速跳閘,青島10kv高壓開(kāi)關(guān)柜(中置開(kāi)關(guān)柜 )故障保護(hù)用電設(shè)備不受電壓下降的影響,青島10kv高壓開(kāi)關(guān)柜(繞線電機(jī)開(kāi)關(guān)柜 )設(shè)計(jì)很多設(shè)備會(huì)因?yàn)殡妷合陆刀鴵p壞。青島10kv高壓開(kāi)關(guān)柜(鼠籠電機(jī)開(kāi)關(guān)柜 )結(jié)構(gòu)
過(guò)電壓脫口跟欠電壓脫口的原理基本一樣,青島10kv高壓開(kāi)關(guān)柜(源創(chuàng)開(kāi)關(guān)柜 )故障停電當(dāng)電壓大于設(shè)定值時(shí),青島10kv高壓開(kāi)關(guān)柜(五防開(kāi)關(guān)柜 )母線安裝方案就會(huì)使斷路器跳閘。青島10kv高壓開(kāi)關(guān)柜(一體化開(kāi)關(guān)柜 )柜后放電
通常,青島10kv高壓開(kāi)關(guān)柜(源創(chuàng)生產(chǎn)的開(kāi)關(guān)柜 )主母線多大在高壓開(kāi)關(guān)柜(高低壓無(wú)線開(kāi)關(guān)柜 )里,青島10kv高壓開(kāi)關(guān)柜(可遠(yuǎn)程控制的開(kāi)關(guān)柜 )原理圖也會(huì)通俗叫做低電壓保護(hù)和過(guò)電壓保護(hù)。青島10kv高壓開(kāi)關(guān)柜(山東開(kāi)關(guān)柜 )故障
