首先判斷跳閘的空氣開(kāi)關(guān)是家中配電箱內(nèi)的總開(kāi)關(guān)還是分路出線開(kāi)關(guān)。如總開(kāi)關(guān)未跳閘，只是分路開(kāi)關(guān)跳閘，則說(shuō)明大功率電器供電線路接線有問(wèn)題，ETAON LZM塑殼斷路器LZMC2-4-A250，即多件大功率電器接在同一分路開(kāi)關(guān)上，此類情況，ETAON LZM塑殼斷路器LZMC2-4-A250，將大功率電器線路調(diào)整至負(fù)荷輕的分路開(kāi)關(guān)即可（建議大功率電器使用單獨(dú)的分路開(kāi)關(guān)）；如分路開(kāi)關(guān)沒(méi)跳閘，總開(kāi)關(guān)跳閘，ETAON LZM塑殼斷路器LZMC2-4-A250，則計(jì)算家用電器功率之和是否超出供電認(rèn)可容量，并檢查總開(kāi)關(guān)容量是否與供電認(rèn)可容量匹配。如家用電器功率之和超出供電認(rèn)可容量，則減少同時(shí)使用的家用電器數(shù)量（特別是大功率家用電器），并向供電公司申請(qǐng)用電增容；如家用電器功率之和未超出供電認(rèn)可容量，同時(shí)需要提醒的是，部分大功率電器啟動(dòng)電流較大，計(jì)算功率時(shí)應(yīng)考慮啟動(dòng)電流造成的影響。

</p> <p> ⑼微型斷路器的脫扣特性 </p> <p> 斷路器脫扣特性分為A、B、C、D、K等幾種，各自的含義如下： </p> <p> A型脫扣特性：脫扣電流為（2～3）In，適用于保護(hù)半導(dǎo)體電子線路，帶小功率電源變壓器的測(cè)量線路，或線路長(zhǎng)且短路電流小的系統(tǒng)； </p> <p> B型脫扣特性：脫扣電流為（3～5）In，適用于住戶配電系統(tǒng)，家用電器的保護(hù)和人身安全保護(hù)； </p> <p> C型脫扣特性：脫扣電流為（5～10）In，適用于保護(hù)配電線路以及具有較高接通電流的照明線路和電動(dòng)機(jī)回路； </p> <p> D型脫扣特性：脫扣電流為（10～20）In，適用于保護(hù)具有很高沖擊電流的設(shè)備，如變壓器、電磁閥等； </p> <p> K型脫扣特性：具備1.2倍熱脫扣動(dòng)作電流和8～14倍磁脫扣動(dòng)作范圍，適用于保護(hù)電動(dòng)機(jī)線路設(shè)備，有較高的抗沖擊電流能力。 </p><p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> <strong>塑殼式斷路器</strong>如何選型（二） </p> <p> 斷路器殼架等級(jí)額定電流是指基本尺寸相同的框架和塑料外殼中能裝的比較大脫扣器的額定電流。 </p> <p> 斷路器額定電流是指斷路器中的脫扣器能長(zhǎng)期通過(guò)的電流，又稱斷路器脫扣器額定電流。 </p> <p> 同一系列中有多種殼架等級(jí)額定電流，同一殼架等級(jí)額定電流中又有多種額定電流。 </p> <p> 例如DZ20系列中有100、225、400、630、800、1250等殼架等級(jí)額定電流，而100殼架等級(jí)額定電流中有16A、20A、25A、32A、40A、50A、63A、80A、100A額定電流；225A殼架等級(jí)額定電流中有100A，125A、160A、180A、200A、225A額定電流。 </p> <p> <br /> </p> <p> <br />

額定絕緣電壓是設(shè)計(jì)斷路器的電壓值，電氣間隙和爬電距離應(yīng)參照此值而定。有些斷路器沒(méi)有明確規(guī)定額定絕緣電壓，應(yīng)將額定工作電壓中比較大值視作額定絕緣電壓，在任何情況下，比較大額定工作電壓不超過(guò)額定絕緣電壓，斷路器的額定絕緣電壓與工頻試驗(yàn)電壓見(jiàn)表1。額定工作電壓是指通斷能力以及使用類別相關(guān)的電壓值，塑殼斷路器的額定工作電壓多為50Hz、380V，但也有50Hz、600V，額定工作電壓380V、50Hz的塑殼斷路器，***不允許用到660V或1140V的電源電壓上。
