熱過載保護(hù):
熱過載(TOL)保護(hù)是通過對(duì)電動(dòng)機(jī)運(yùn)行中熱容量的跟蹤計(jì)算來保護(hù)電動(dòng)機(jī)免于因過熱而縮短壽命或損壞。同時(shí)，過載(TOL)保護(hù)的熱記憶功能對(duì)需要頻繁啟動(dòng)電機(jī)的場(chǎng)合具有重要的意義。過載(TOL)保護(hù)具有熱記憶功能，可以有效地保護(hù)馬達(dá)過熱狀態(tài)下重復(fù)起動(dòng)。裝置摸擬了電機(jī)在各種運(yùn)行狀態(tài)下的熱狀態(tài)，以便最大限度地使用電機(jī)，又能保證電機(jī)的安全。熱過載保護(hù)同時(shí)考慮到了電機(jī)轉(zhuǎn)子和定子的溫升，并充分考慮了三相不平衡對(duì)電機(jī)發(fā)熱的影響。當(dāng)要重新起動(dòng)馬達(dá)時(shí)，裝置會(huì)自動(dòng)判斷馬達(dá)停止運(yùn)行后的溫度是否已下降到可以重新起動(dòng)的限值，是則允許重新起動(dòng)馬達(dá)，否則閉鎖起動(dòng)操作直至電機(jī)溫度下降到滿足重新起動(dòng)的限定條件。
通過修改電動(dòng)機(jī)在冷態(tài)情況下6倍額定電流所允許的過載時(shí)間t6可調(diào)整保護(hù)動(dòng)作特性。
過載(TOL)保護(hù):
保護(hù)動(dòng)作特性曲線經(jīng)計(jì)算模擬存儲(chǔ)在裝置中。脫扣值，告警值、復(fù)位值均可通過參數(shù)設(shè)置或定值修改進(jìn)行調(diào)整。
防爆電機(jī)EExe熱過載保護(hù):
EExe保護(hù)考慮了電機(jī)堵轉(zhuǎn)電流與標(biāo)稱電流之比及相應(yīng)環(huán)境等級(jí)允許的電機(jī)溫度。這些數(shù)據(jù)由電機(jī)制造商提供可直接在裝置上設(shè)置，不需要計(jì)算。
斷相保護(hù):根據(jù)最小線電流和最大線電流的比值判斷是否啟動(dòng)斷相保護(hù)。斷相保護(hù)功能應(yīng)設(shè)定相關(guān)參數(shù)，如告警值、脫扣值、脫扣延時(shí)時(shí)間等。保護(hù)脫扣可為延時(shí)脫扣或瞬時(shí)脫扣。
三相不平衡:根據(jù)最小線電流和最大線電流的比值判斷是否啟動(dòng)三相不平衡保護(hù)。
該功能應(yīng)設(shè)定相關(guān)參數(shù)，如告警值、脫扣值、脫扣延時(shí)時(shí)間等。保護(hù)動(dòng)作可為延時(shí)脫扣或只告警不脫扣。
堵轉(zhuǎn)保護(hù):根據(jù)最大線電流測(cè)量值和電機(jī)額定電流的比值判斷是否啟動(dòng)堵轉(zhuǎn)保護(hù),該功能應(yīng)設(shè)定相關(guān)參數(shù)，如脫扣值，脫扣延時(shí)時(shí)間。保護(hù)動(dòng)作為延時(shí)脫扣。
欠電壓保護(hù):主電路電壓低于整定值時(shí)啟動(dòng)低電壓保護(hù)，該功能應(yīng)設(shè)定其他參數(shù),如告警值、脫扣值、脫扣延時(shí)時(shí)間等。保護(hù)動(dòng)作為延時(shí)脫扣。
自動(dòng)起動(dòng):在電壓突降后，根據(jù)電壓重新恢復(fù)時(shí)的不同情況，M102裝置 可以讓電機(jī)以不同的方式重起動(dòng)。自動(dòng)重起動(dòng)的情況可以分為以下三種:
■電壓在自動(dòng)重合閘時(shí)間(需要預(yù)先設(shè)定)之前恢復(fù)，自動(dòng)重起動(dòng)將立即執(zhí)行; 電壓恢復(fù)發(fā)生在自動(dòng)重合閘時(shí)間(需要預(yù)先設(shè)定)過后但仍在最長欠壓時(shí)間
(需要預(yù)先設(shè)定) 之前，M102裝 置按電機(jī)順序起動(dòng)執(zhí)行。 即電機(jī)自動(dòng)重起動(dòng)將在分組順序起動(dòng)延時(shí)時(shí)間(可調(diào))過后開始。
電壓恢復(fù)發(fā)生在最長欠壓時(shí)間(需要預(yù)先設(shè)定)之后，M102裝置將不會(huì)執(zhí)行重新啟動(dòng)。
裝置的自動(dòng)重起動(dòng)功能可以按標(biāo)準(zhǔn)型與增強(qiáng)型兩類選配。
標(biāo)準(zhǔn)型即按上述情況執(zhí)行;增強(qiáng)型除了標(biāo)準(zhǔn)型的功能外，還完善了第四種情況:
■若兩次發(fā)生 電壓突降情況之間的間隔在1秒之內(nèi)，并且每次發(fā)生的時(shí)間不超過200毫秒，M102裝置將執(zhí)行電機(jī)順序起動(dòng)。即電機(jī)自動(dòng)重起動(dòng)將在分組順序起動(dòng)延時(shí)時(shí)間(可調(diào))過后開始。
自動(dòng)重起動(dòng)功能可以有效地保護(hù)瞬時(shí)電壓跌落對(duì)電機(jī)運(yùn)行的干擾。
