只作為電源隔離用的刀開關(guān)則不需要滅弧裝置。用于電解、電鍍等設(shè)備中的大電流刀開關(guān)的額定電流可高達(dá)數(shù)萬安。這類刀開關(guān)一般采用多回路導(dǎo)體并聯(lián)的結(jié)構(gòu)，并可用水冷卻的方式散熱來提高刀開關(guān)導(dǎo)體所能承載的電流密度。

刀開關(guān)在電路中要求能承受短路電流產(chǎn)生的電動(dòng)力和熱的作用。因此,在刀開關(guān)的結(jié)構(gòu)設(shè)計(jì)時(shí),要確保在很大的短路電流作用下，觸刀不會(huì)彈開、焊牢或燒毀。對要求分?jǐn)嘭?fù)載電流的刀開關(guān)，則裝有快速刀刃或滅弧室等滅弧裝置。

HD13B-1500/31刀開關(guān)按照極數(shù)可以分為單極刀開關(guān)、雙極刀開關(guān)和三極刀開關(guān)；按照轉(zhuǎn)換方式可以分為單投式刀開關(guān)、雙投式刀開關(guān)；按操作方式可分為手柄直接操作式和杠桿式刀開關(guān)。圖1所示為三極單投式刀開關(guān)的電路圖，它可用來接通或分?jǐn)嚯娐?/span>A,也可作為將電路A與電源隔離之用。圖2為單極雙投式刀開關(guān)，它可用來接通或分?jǐn)嚯娐?/span>A或電路B，也可將電源向電路A供電轉(zhuǎn)換到向電路B供電。
