工作原理
CM2-160L/3308
CM2-160L/3308
低壓斷路器的主觸點(diǎn)是靠手動(dòng)操作或電動(dòng)合閘的。主觸點(diǎn)閉合后,自由脫扣機(jī)構(gòu)將主觸點(diǎn)鎖在合閘位置上。過電流脫扣器的線圈和熱脫扣器的熱元件與主電路串聯(lián),欠電壓脫扣器的線圈和電源并聯(lián)。
當(dāng)電路發(fā)生短路或嚴(yán)重過載時(shí),過電流脫扣器的銜鐵吸合,使自由脫扣機(jī)構(gòu)動(dòng)作,主觸點(diǎn)斷開主電路。
當(dāng)電路過載時(shí),熱脫扣器的熱元件發(fā)熱使雙金屬片上彎曲,推動(dòng)自由脫扣機(jī)構(gòu)動(dòng)作,主觸點(diǎn)斷開主電路。
當(dāng)電路欠電壓時(shí),欠電壓脫扣器的銜鐵釋放,也使自由脫扣機(jī)構(gòu)動(dòng)作,主觸點(diǎn)斷開主電路。
當(dāng)按下分勵(lì)脫扣按鈕時(shí),分勵(lì)脫扣器銜鐵吸合,使自由脫扣機(jī)構(gòu)動(dòng)作,主觸點(diǎn)斷開主電路。
低壓斷路器是按熄滅介質(zhì)的不同分類的,利用空氣作為滅弧介質(zhì)的斷路器,稱之為空氣斷路器(空氣開關(guān));利用惰性氣體作為滅弧介質(zhì)的斷路器,稱之為惰性氣體斷路器(惰性氣體開關(guān));利用油作為滅弧介質(zhì)的斷路器,稱之為油斷路器(油開關(guān))。
⑴額定電壓
斷路器銘牌上的額定電壓是指斷路器主觸頭的額定電壓,是保證接觸器觸頭*正常工作的電壓值。
(2)額定電流
接觸器銘牌上的額定電流是指路器主觸頭的額定電流,是保證接觸器觸頭*正常工作的電流值。
⑶脫扣電流
脫扣電流是使過電流脫扣器動(dòng)作的電流設(shè)定值,當(dāng)電路短路或負(fù)載嚴(yán)重超載,負(fù)載電流大于脫扣電流時(shí),斷路器主觸頭分?jǐn)唷?/p>
⑷過載保護(hù)電流、時(shí)間曲線
過載保護(hù)電流、時(shí)間曲線,為反時(shí)限特性曲線,過載電流越大,熱脫扣器動(dòng)作的時(shí)間就越短。
⑸欠電壓脫扣器線圈的額定電壓
欠電壓脫扣器線圈的額定電壓一定要等于線路額定電壓。
⑹分勵(lì)脫扣器線圈的額定電壓
分勵(lì)脫扣器線圈的額定電壓一定要等于控制控制電源電壓。

斷路器的分?jǐn)嗄芰χ笜?biāo)有兩種:額定極限短路分?jǐn)嗄芰cu和額定運(yùn)行短路分?jǐn)嗄芰cs。

對塑殼式斷路器而言, Ics只要大于25%Icu就算合格,目前市場上斷路器的Ics大多數(shù)在(50%—75%)Icu之間。
⑻限流分?jǐn)嗄芰?/p>
限流分?jǐn)嗄芰κ侵鸽娐钒l(fā)生短路時(shí),斷路器跳閘時(shí)限制故障電流的能力。電路發(fā)生短路時(shí),斷路器觸頭快速打開,產(chǎn)生電弧,相當(dāng)于在線路中串入1個(gè)迅速增加的電弧電阻,從而限制了故障電流的增加,降低了短路電流的電磁效應(yīng)、電動(dòng)效應(yīng)和熱效應(yīng)對斷路器和用電設(shè)備的不良影響,延長斷路器的使用壽命。斷路器斷開時(shí)間越短,限流效果就越好,Ics就越接近Icu。
