Kodi RCD

Popanda kudziwa zimene RCD (yotsalira chipangizo panopa), kuonetsetsa machitidwe abwino zipangizo zamagetsi ndi zovuta. Mukhoza kumva nkhani za mmene ntchito makina ochapira zodabwitsa magetsi pamene anakhudza pa ntchito. Chinthu chomwecho chimachitika ngati pa nthawi yomweyo kukhudza thupi ntchito kompyuta ndi radiators. zodabwitsazi amachita kulibe, si wonongeka, koma mbali ya zamagetsi popanda grounding.

Kwambiri pa magetsi kulola RCD.

ndi RCD ndi chiyani? chipangizo Izi ndi liwilo dera baka ichidachi, ozikidwa pa kuyerekezera mafunde kuti afanane katundu ndi kubwerera ku maukonde, akuchita dera otseguka pamene lochitira (masiyanidwe panopa zikuoneka). Ndiko kuti, ngati penapake mu gawo kutetezedwa kwa mzere ikudontha mu nthaka, chipangizo detects ndi De-mphamvu mzere.

Taganizirani mfundo za RCD lapansi. The mtima chipangizo ndi thiransifoma panopa, amatchedwanso masiyanidwe. Amakhala windings atatu: chachikulu (L1) ndi sekondale (L2), motero, m'gulu la mipata gawo ndi mawaya ndale, ndi wachitatu (L3) chikugwirizana ndi limagwirira choyambitsa. Malinga limagwirira kuphedwa angathe kupatsidwa mkulu tilinazo kulandirana (RCD electromechanical mtundu) kapena zigawo pakompyuta, amangoona ndi comparator ndi mkuzamawu (E-mtundu). limagwirira Izi choyambitsa ali umakaniko zolumukizidwa ndi yoyendetsa galimoto ndi yopuma mphamvu ojambula.

Pamene katundu chikugwirizana ndi RCD mwa kumulowetsa L1 ndi L2, Umayenda panopa. Popeza ntchito yachibadwa mtengo wa panopa amaperekedwa kwa ogula ofanana exiting, ndiye maginito awo okwana kamwazi kwaiye kwatha ndi ziro (a windings ali pafupi, panopa imatsogoleredwa oppositely). Choncho, koyilo L3 si mphamvu iliyonse. Akafuna ntchito kwambiri kusintha nthawi yomweyo wokhudza thupi pansi ndi kuonongeka unit pansi voteji. Pankhaniyi, gawo wochititsa (L1 kumulowetsa) zina panopa kwakukulukulu panopa kumulowetsa L2. Ndipotu, pali kusiyana, chifukwa panopa kupita dera gawo wochititsa, adzapita mu nthaka mwa munthu, osati anabwerera RCD lapansi. The kamwazi maginito kuposa akulipira koyilo L1 L2 otaya kanthu, motero, kwaiye ndi kamwazi maginito amalenga kumulowetsa L3 yaing'ono panopa zokwanira ntchito kwa kulandirana kapena circuitry pakompyuta ndi actuation wa actuator chimene angalandire ojambula mphamvu.

Munthu amene akudziwa chimene RCD, akudziwa mmene angachitire cheke yosavuta ntchito zake. Pa nkhani ya RCDs uliwonse upereke "Kuyesedwa" batani, kuwonekera pa zimene mungathe kuyesa magwiridwe chipangizo. Kukanikiza mwachidule shunts imodzi windings, kuchotsa izo kuchokera ku dera opangidwa ndi kubwezera maginito kamwazi, kotero chipangizo kumayambika.

A funso lophweka - mmene kugwirizanitsa RCD? chipangizo ndi kuti wokwera mu tandem ndi lophimba yaotomatiki, chifukwa lilibe ikukhudzana ndi mu atomu zimatulutsa, motero, amateteza zimamuchulukira (matenthedwe) ndi mkulu-panopa yochepa dera (SC). Zifukwa panopa akhoza kuwononga RCD, monga mode uyu wa opaleshoni kutayikira zimachokeradi, koma mtengo wa masiku ano kuchuluka kwa mfundo zabwino kwambiri. Mwa njira, ichi ndi chifukwa chake kuli kofunika kusankha pamene kugula katundu ndi RCD oveteredwa panopa. Mwachitsanzo, ngati makina kuti analilembera 16 amp, ndi RCD ayenera kukhala osachepera amperes 25. Mawu osavuta, ndi oveteredwa panopa RCD ndi - ndi chovomerezeka zatsopano zigawo zikuluzikulu za ochititsa ake.

Mwachionekere, mu nthawi yathu, m'pofunika kumvetsa funso, kodi RCD, koma angathe kugwiritsa ntchito kunyumba kwanu. Ndipotu ndi chitetezo zina m'banjamo.
