滅弧裝置 容量在10A以上的接觸器都有滅弧裝置,對(duì)于小容量的接觸器,常采用雙斷口觸點(diǎn)滅弧、電動(dòng)力滅弧、相間弧板隔弧及陶土滅弧罩滅弧。對(duì)于大容量的接觸器,采用縱縫滅弧罩及柵片滅弧
觸點(diǎn)系統(tǒng) 包括主觸點(diǎn)和輔助觸點(diǎn)。主觸點(diǎn)用于通斷主電路,通常為三對(duì)常開觸點(diǎn)。輔助觸點(diǎn)用于控制電路,起電氣聯(lián)鎖作用,故又稱聯(lián)鎖觸點(diǎn),一般常開、常閉各兩對(duì)。
按主觸點(diǎn)極數(shù)分 可分為單極、雙極、三極、四極和五極接觸器。單極接觸器主要用于單相負(fù)荷,如照明負(fù)荷、焊機(jī)等,在電動(dòng)機(jī)能耗制動(dòng)中也可采用;雙極接觸器用于繞線式異步電機(jī)的轉(zhuǎn)子回路中,起動(dòng)時(shí)用于短接起動(dòng)繞組;三極接觸器用于三相負(fù)荷,例如在電動(dòng)機(jī)的控制及其它場(chǎng)合,使用為廣泛;四極接觸器主要用于三相四線制的照明線路,也可用來控制雙回路電動(dòng)機(jī)負(fù)載;五極交流接觸器用來組成自耦補(bǔ)償起動(dòng)器或控制雙籠型電動(dòng)機(jī),以變換繞組接法
按滅弧介質(zhì)分 可分為空氣式接觸器、真空式接觸器等。依靠空氣絕緣的接觸器用于一般負(fù)載,而采用真空絕緣的接觸器常用在煤礦、石油、化工企業(yè)及電壓在660V和1140V等一些特殊的場(chǎng)合
按有無觸點(diǎn)分 可分為有觸點(diǎn)接觸器和無觸點(diǎn)接觸器。常見的接觸器多為有觸點(diǎn)接觸器,而無觸點(diǎn)接觸器屬于電子技術(shù)應(yīng)用的產(chǎn)物,一般采用晶閘管作為回路的通斷元件。由于可控硅導(dǎo)通時(shí)所需的觸發(fā)電壓很小,而且回路通斷時(shí)無火花產(chǎn)生,因而可用于高操作頻率的設(shè)備和易燃、易爆、無噪聲的場(chǎng)合
