1, Mfundo Yoyeserera:
a) Kupirira Mayeso Aulimi:
Mfundo yoyambira yogwira ntchito ndi iyi: Fananizani zomwe zatulutsidwa ndi zida zoyesedwa pamtunda wa magetsi apamwamba ndi magetsi oyeserera omwe ali ndi chiweruziro chaposachedwa. Ngati kutaya kwapano kumakhala kocheperako kuposa mtengo womwe umayambitsa, chida chimayambitsa mayeso. Pamene kutaya kwaposachedwa kuli kwakukulu kuposa kuweruza komwe kumachitika, mphamvu yamayeso imadulidwa ndipo alamu omveka ndi mawonekedwe amatumizidwa, kuti adziwe mphamvu ya gawo loyesedwa.
Pa mfundo yoyamba yoyeserera,
Mphamvu yolimbana ndi tester imakhala yopangidwa makamaka ndi ma ac magetsi apamwamba kwambiri, wowongolera nthawi yayitali, kudziwika ndi dera lonse la zisonyezo, zisonyezo zisonyezo. Mfundo yofunika kwambiri yogwira ntchito ndi iyi: Chiwerengero cha kutaya zinthu zomwe zakonzedwa ndi zoyeserera zam'madzi zomwe zimapangidwa ndi magetsi kwambiri poyerekeza ndi magetsi omwe amakuweruzani. Ngati kutaya komwe kwapezeka ndi kocheperako kuposa mtengo womwe upangiri, chida chomwe chimatha kuyesa, pomwe magetsi odziwika bwino kwambiri kupirira mphamvu yoyesedwa.
b) Kusokoneza:
Tikudziwa kuti magetsi akumayeserera nthawi zambiri amakhala 500V kapena 1000v, yomwe ikufanana poyesa kuyesa magetsi. Pansi pa voliyumu iyi, chida chimakhala chamtengo wapatali, kenako chimawakonzera zomwe zikuchitika mkati mwa madera. Pomaliza, imadutsa lamulo la ohm: r = u / i / i / kuti, komwe muli 500V kapena 1000v adayesedwa, ndipo ine ndiye kutayikira komwe kulipo. Malinga ndi kuthana ndi magetsi oyeserera, titha kumvetsetsa kuti ndi ochepa kwambiri, ochepera 1 μ a.
Itha kuwoneka kuchokera pamwambapa kuti mfundo yoyeserera ndiyofanana ndendende ndi yolimbana ndi mayeso oyeserera, koma ndi mawu ena okha chabe a Lamulo la Ohh. Kutulutsa kwamakono kumagwiritsidwa ntchito pofotokoza momwe zinthu sizingayesedwe, pomwe kusokonekera kumatsutsana.
2, cholinga cha magetsi kupirira mayeso:
Magetsi amapilira mayeso ndi mayeso osawonongeka, omwe amagwiritsidwa ntchito kuzindikira ngati mphamvu ya zinthu zokwanira ndizoyenerera kwambiri. Imagwiritsa ntchito voliyumu yayikulu ku zida zoyesedwa kwa nthawi inayake kuti zitsimikizire kuti magwiridwe antchito ndi amphamvu mokwanira. Chifukwa china choyeserera ichi ndikuti zithanso kudziwa zofooka zina, monga mtunda wosakwanira wa mtunda wa magetsi komanso chilolezo chokwanira pamapangidwe.
3, magetsi amapilira magetsi magetsi:
Pali lamulo wamba la magetsi oyeserera = mphamvu yamagetsi × 2000v.
Mwachitsanzo: Ngati mphamvu ya mphamvu ya mayeso ndi 220V, voliyumu yamayeso = 220v × 2 + 1000v = 14000v = 1480v = 1480v.
Nthawi zambiri, kupirira magetsi nthawi yoyesedwa ndi miniti imodzi. Chifukwa cha kuchuluka kwa mayeso ogwirizana pamagetsi pa mzere, nthawi yoyeserera imachepetsedwa kwa masekondi ochepa. Pali mfundo yomwe ilipo. Nthawi yoyesedwa imachepetsedwa kwa masekondi 1-2 okha, magetsi oyeserera ayenera kuchuluka ndi 10-20%, kotero kuti atsimikizire kuti kudalirika kwakanthawi kochepa.
4, alarm zamakono
Kukhazikitsidwa kwa Alarm zamakono kudzatsimikizika malinga ndi zinthu zosiyanasiyana. Njira yabwino ndikupanga mayeso aposachedwa kwa zitsanzo pasadakhale, pezani mtengo wambiri, kenako ndikuwona mtengo wokwera kwambiri kuposa mtengo wambiri monga momwe muliri. Chifukwa kutaya kwa zida zamakono zomwe zayesedwa sizingachitike, ndikofunikira kuonetsetsa kuti alarm omwe alipo ndi okwanira kuti apewe kulakwitsa chifukwa cholakwitsa. Nthawi zina, ndizothekanso kudziwa ngati zitsanzozo zimalumikizana ndi kutha kwa magetsi a magetsi pokhazikitsa alamu otsika.
5, kusankha ma AC ndi DC mayeso
Mayeso oyeserera, miyezo yambiri ya chitetezo imalola kugwiritsa ntchito ma ac kapena DC magetsi popirira magetsi amagetsi. Ngati magetsi oyeserera a Mac amagwiritsidwa ntchito, pomwe nsonga ya mphamvu ya pachimake imafikiridwa, miyeso yoyesedwa imayesedwa ndi zovuta kwambiri pomwe mtengo wamtengo wapatali ukakhala wabwino kapena wosalimbikitsa. Chifukwa chake, ngati atasankha kusankha kugwiritsa ntchito magetsi a DC Mwachitsanzo: 1500V ac magetsi, chifukwa cha DC Vologe kuti ipangitse kupsinjika komweko kuyenera kukhala 1500 × 1.41V ndi magetsi a 2121V DC.
Chimodzi mwazinthu zabwino za kugwiritsa ntchito magetsi a DC ndikuwonetsetsa DC, zomwe zikuyenda bwino kudzera mu chipangizo cha Alamu omwe ali ndi vuto la magetsi ndi njira zenizeni kudzera mu zitsanzo. Ubwino wina wogwiritsa ntchito DC ndikuti mphamvuyo ikhoza kugwiritsidwa ntchito pang'onopang'ono. Mphamvu ikachuluka, wothandizirayo amatha kudziwa momwe amathandizira kudzera pachitsanzo cha chiwonetsero chisanafike. Ndikofunikira kudziwa kuti mukamagwiritsa ntchito magetsi a DC kupirira tester, zitsanzozo ziyenera kutulutsidwa pambuyo poyesedwa pambuyo poyesedwa chifukwa cha kuchuluka kwa carriit. M'malo mwake, ziribe kanthu kuchuluka kwa ma voliyumu omwe amayesedwa ndi mawonekedwe a malonda, ndibwino kuti pakhale zotulutsa musanagwiritse ntchito malonda.
Choyipa cha magetsi a DC Kupirira mayeso ndikuti zitha kugwiritsa ntchito magetsi wamba mbali imodzi, ndipo sangathe kugwiritsa ntchito zovuta ziwiri poyesedwa ngati mayeso a magetsi. Kuphatikiza apo, chifukwa magetsi a DC amayesa kupanga, mtengo wa mayeso a DC ndipamwamba kuposa mayeso a ma ac.
Ubwino wa magetsi a magetsi ndikuti imatha kudziwa polandara yonse yopita polandarity, yomwe ili pafupi ndi zochitika. Kuphatikiza apo, chifukwa magetsi a ac sadzalipira ndalamazo, nthawi zambiri, mtengo wokhazikika wapano ungapezeke mwa kutulutsa magetsi ofanana popanda gawo limodzi. Komanso, mayeso atalizidwa, palibe mawu osokosera omwe amafunikira.
Kuperewera kwa magetsi opirira ma ac ndikuti ngati pali gawo lalikulu la Y ili pamzere woyesedwa, nthawi zina, mayeso a AC adzamizidwa molakwika. Miyezo yambiri ya chitetezo imalola ogwiritsa ntchito kuti asalumikizidwe y capoctors musanayesere, kapena m'malo moyesa mayeso a DC. Pamene magetsi a DC ndikupirira mayeso amawonjezeredwa ku y cartacitance, sizingafanane molakwika chifukwa cactacition sichingalole zaposachedwa pano.
