描述
閘刀開關(guān)是一種手動(dòng)配電電器。主要用來隔離電源或手動(dòng)接通與斷開交直流電路,也可用于不頻繁的接通與分?jǐn)囝~定電流以下的負(fù)載,如小型電動(dòng)機(jī)、電爐等。
閘刀刀開關(guān)是最經(jīng)濟(jì)但技術(shù)指標(biāo)偏低的一種刀開關(guān)。閘刀開關(guān)也稱開啟式負(fù)荷開關(guān)。
圖是它的外形與結(jié)構(gòu)圖,它主要有:與操作瓷柄相連的動(dòng)觸刀、靜觸頭刀座、熔絲、進(jìn)線及出線接線座,這些導(dǎo)電部分都固定在瓷底板上,且用膠蓋蓋著。所以當(dāng)閘刀合上時(shí),操作人員不會(huì)觸及帶電部分。膠蓋還具有下列保護(hù)作用:(1)將各極隔開,防止因極間飛弧導(dǎo)致電源短路;(2)防止電弧飛出蓋外,灼傷操作人員;(3)防止金屬零件掉落在閘刀上形成極間短路。熔絲的裝設(shè),又提供了短路保護(hù)功能。
