Zisho ukuthini izinhlamvu B kanye no-K kukhoyili yokuthungela?

Lapho kukhona ukuwohloka okunjalo ekusebenzeni kwenjini evuthayo yangaphakathi njengokunyamalala kwenhlansi noma inhlansi ebuthakathaka, ukungenzi lutho okungazinzile, ukungakwazi ukulungisa isivinini esingenzi lutho, ukuqala kanzima noma ukungakwazi ukuqala injini evuthayo yangaphakathi, ukucwilisa kanye nokugxuma lapho iqala futhi inyakaze, njll., khona-ke kunengqondo ukuxilonga ukusebenza kwekhoyili yokuthungela . Ukuze wenze lokhu, ungase udinge ukwazi ukuqanjwa kwezinhlamvu B kanye no-K kukhoyili.

Zisho ukuthini izinhlamvu B kanye no-K kukhoyili yokuthungela?

Ngokwetheminali ngo + uphawu noma incwadi B (ibhethri) inikwa amandla yibhethri, ngohlamvu K iswishi ixhunyiwe. Imibala yezintambo ezimotweni ingahluka, ngakho-ke kulula ukulandelela ukuthi iyiphi eya lapho.

*Amakhoyili okuthungela angahluka ekuqineni kokuphenduka.

Ungaxhuma kanjani ikhoyili yokuthungela ngendlela efanele?

Kungakhathaliseki ukuthi yiziphi izici zemoto, uxhumano luyafana:

• ucingo oluphuma kukhiye lunsundu futhi luxhunywe kutheminali ngophawu “+” (uhlamvu B);
• ucingo olumnyama oluvela ku-mass luxhunywe ku- "K";
• itheminali yesithathu (esivaloni) ingeyocingo olunamandla kagesi.

Ilungiselela isheke

Ukuze uhlole ikhoyili yokuthungela, uzodinga iringi engu-8 mm noma isikrufu esivulekile, kanye nesihloli (i-multimeter noma idivayisi efanayo) enemodi ye-ohmmeter.

Ungakwazi ukuxilonga ikhoyili yokuthungela ngaphandle kokuyikhipha emotweni:

• khipha itheminali enegethivu ebhethrini;
• nqamula ucingo olunamandla kagesi aphezulu kukhoyili yokuthungela;
• nqamula izintambo eziholela kumatheminali amabili ekhoyili.

Ukwenza lokhu, sebenzisa isikrufu esingu-8 mm ukuze ukhulule amantongomane avikela izintambo kumatheminali. Sinqamula izintambo, sikhumbula isikhundla sazo, ukuze singaziphambanisi lapho sizifaka.

i-coil diagnostics

Sihlola ukusebenza kwekhoyili yokuthungela.

Ukuze senze lokhu, sixhuma i-probe eyodwa yomhloli kutheminali ethi "B", uphenyo lwesibili kutheminali ethi "K" - okukhiphayo kokujikajika okuyinhloko. Sivula idivayisi kumodi ye-ohmmeter. Ukumelana nokuvunguza okuyisisekelo okunempilo kwekhoyili yokuthungela kufanele kusondele ku-zero (0,4 - 0,5 ohms). Uma iphansi, khona-ke kukhona isifunda esifushane, uma siphakeme, kukhona isifunda esivulekile ekujikelezeni.

Sihlola ukusebenza kwekhoyili yokuthungela yesibili (high-voltage)

Ukuze senze lokhu, sixhuma i-tester probe eyodwa kutheminali ethi "B" yekhoyili yokuthungela, bese i-probe yesibili iye ekuphumeni kwentambo ene-voltage ephezulu. Sikala ukumelana. Ukuze uthole ukuvuthwa kwesibili okusebenzayo, kufanele kube ngu-4,5 - 5,5 kOhm.

Ukuhlola ukumelana nokufakwa emhlabathini. Ukuze uthole isheke elinjalo, kuyadingeka ukuthi i-multimeter ibe nemodi ye-megohmmeter (noma i-megohmmeter ehlukile iyadingeka) futhi ingakala ukumelana okuphawulekayo. Ukwenza lokhu, sixhuma i-probe eyodwa yokuhlola kutheminali ethi “B” yekhoyili yokuthungela, bese ucindezela uphenyo lwesibili emzimbeni wayo. Ukumelana ne-insulation kumele kube phezulu kakhulu - 50 mΩ noma ngaphezulu.

Uma okungenani isheke elilodwa kwamathathu libonisa ukungasebenzi kahle, kufanele kushintshwe ikhoyili yokuthungela.
