Kodi kufufuza thiransifoma multimeter? malangizo

Nthawi zambiri muyenera mutidziwe zapatsogolo ndi funso mmene fufuzani thiransifoma. Ndipotu, ngati sichitha, kapena Kusakhazikika kudzakhala kovuta kuyang'ana chifukwa cha zida kulephera. Izi ndi magetsi chipangizo yosavuta yomwe oterewa ndi multimeter ochiritsira. Tiyeni tiwone momwe angachitire izo.

zida ndi chiyani?

Kodi kufufuza thiransifoma, ngati simukudziwa matabwa ake? Taganizirani mfundo ya kanthu ndipo zosiyanasiyana zida yosavuta. Pa maginito pakati TACHIMATA mkuwa waya coils mwachindunji gawo kotero kuti maganizo anakhala otaya ndi sekondale kumulowetsa.

Mphamvu kutengerapo ku sekondale kumulowetsa imagwiridwa mu contactless unsembe. Pali kale pafupifupi zimaonekeratu momwe fufuzani thiransifoma. Mofananamo prozvanivat ochiritsira inductance ohmmeter. The coils kupanga kukana kuti angathe kuyeza. Komabe, njira imeneyi ntchito pamene mtengo chandamale amadziwika. Ndithudi, kukana zingasiyane kapena pansi chifukwa cha magetsi. Akutchedwa interturn lalifupi dera.

Chotero chipangizo sadzakhala apereke kutchulidwa voteji ndipo panopa. Ohmmeter kokha lotseguka dera kapena akufa yochepa. Pakuti zina ntchito matenda ndi earthing ohmmeter chomwecho. Kodi kufufuza thiransifoma windings mosadziwa anapezazo?

Izi anatsimikiza ndi makulidwe a mawaya exiting. Ngati thiransifoma ndi kuchepa kwa ochititsa osachiritsika a kutsogolera adzakhala chachikulu. Ndipo mogwirizana M'malo mwake: ndi mawaya athandizira sitepe-mmwamba chachikulu. Ngati awiri kumulowetsa linanena bungwe, makulidwe akhoza kukhala chomwecho, tiyenera kukumbukira za izo. Njira yabwino kuona zolemba ndi kupeza zipangizo specifications.

mitundu

Transformers anawagawa m'magulu awa:

• Kutsitsa ndi kulera.
• Mphamvu zambiri kutumikira kuchepetsa kotunga voteji.
• tiransifoma zatsopano kupereka panopa nthawi zonse ogula ndi posungira ake mkati osiyanasiyana anakonzeratu.
• Wosakwatira ndi Mipikisano gawo.
• Kuwotcherera zolinga.
• Kugunda.

Malinga ndi cholinga zida ndi wosinthika ndi mfundo za malowedwe athu kwa funso mmene fufuzani thiransifoma. Multimeter zotheka kuti alire chabe-kakulidwe chipangizo. Mphamvu makina kale amafuna njira ina kuti kusaka.

njira kupitiriza

ohmmeter njira matenda chingatithandize ndi funso mmene kutsimikizira mphamvu thiransifoma. Prozvanivat kukana pakati pa chiyambi cha munthu kumulowetsa. Motero kukhulupirika kwa akonzedwa kondakitala. Pamaso thupi kuti agwire chiphasochi pa pakalibe madipoziti mpweya, sagging chifukwa Kutentha zida.

Kenako, kuyeza mtengo ziliri pa ohms fanizirani ndi pasipoti lapansi. Ngati iwo palibe, pamafunika diagnostics zina zikundithandiza. Prozvonit analimbikitsa aliyense chipangizo linanena bungwe kwa nyumba zitsulo, amene chikugwirizana pansi.

Isanafike muyeso wa, kusagwirizana malekezero onse a thiransifoma lapansi. Kusagwirizana kwa unyolo, ndipo akulimbikitsidwa moyo wawo. Komanso fufuzani kupezeka kwa dera amagetsi, chomwe nthawi zambiri kupezeka zitsanzo amakono mphamvu. Kuyenera vypayat pamaso afufuze.

kukana wopandamalire limasonyeza kutchinjiriza lonse. Mfundo za kilohms ochepa kale kuutsa kukayikirana za kuwonongedwa kwa nyumba ya. Zingakhalenso chifukwa anapeza dothi, fumbi kapena chinyontho mpweya kusiyana chipangizo.

moyo

Mayesero akutsatiridwa ndi mphamvu umaperekedwa pamene pali funso mmene kufufuza thiransifoma interturn dera yochepa. Ngati tizindikira kufunika kwa chipangizo kotunga voteji, limene lakonzedwa kuti thiransifoma, ndi voltmeter kuyeza phindu la kusakhala ndi chochita. Ndiko kuti, mawaya kutsogolera ali mu mlengalenga.

Ngati voteji chosiyana ndi mwadzina, izo anamaliza kumulowetsa dera yochepa windings wa. Ngati pa ntchito lomveka crackle, arcing, chotero thiransifoma bwino zimitsani. Ndi wolakwika. Pali tolerances mu miyeso ndi:

• Pakuti voteji mfundo zingasiyane ndi 20%.
• Kwa mlingo kulimbana ndi mu osiyanasiyana mfundo 50% pasipoti lapansi.

metering ammeter

Tiyeni kudziwa mmene fufuzani thiransifoma panopa. Iwo ali nawo mu mzere wa nthaŵi zonse kapena kudzikonda anapanga. Nkofunika kuti phindu panopa ndi osachepera mwadzina ndi. ammeter miyezo ikuchitika mu dera chachikulu ndi sekondale.

zikuonetsa Current akuyerekezedwa ndi sekondale ku dera chachikulu. More ndendende, agawa mfundo yoyamba anayeza pa sekondale kumulowetsa. Kusintha chiŵerengero ayenera kumwedwa kwa m'bukhu, ndi kuyerekeza ndi anthu akamagwira kuwerengetsera. Zotsatira ayenera kukhala yemweyo.

The thiransifoma panopa sangathe anayeza pa zachabe. Pa mbali yachiwiri Pankhaniyi akhoza kupangidwa voltages kwambiri zimene zingasokoneze kutchinjiriza ndi. Muyeneranso kusunga polarity, amene zidzakhudza ntchito kwa Kulumikizana lonse.

Mavuto Common

Musanayambe fufuzani thiransifoma mayikirowevu, kupereka kuwonongeka kawirikawiri mitundu amene atathana popanda multimeter a. Nthawi zambiri zipangizo mphamvu ndithu chifukwa dera yochepa. Iwo anakhazikitsa anayendera wa matabwa dera zolumikizira, kugwirizana. Pasanathe mawotchi kuwonongeka amapezeka thiransifoma nyumba ndi pakati.

Mawotchi avale wa mankhwala a malo ndi thiransifoma pa makina kusuntha amapezeka. kotunga Large kumulowetsa amafuna kuzirala zonse. Sanamwe, mwina overheat ndi kusungunula kutchinjiriza ndi.

TDKS

Tidzamva mmene kukayendera kugunda kwa mtima wanu thiransifoma. An ohmmeter zikhoza kukhazikitsidwa yekha kukhulupirika kwa windings wa. Mwachangu chipangizo udzakhazikitsidwe polumikiza dera, mmene capacitor ali nawo, katundu ndi jenereta phokoso.

Pa Kuyambitsa chachikulu kumulowetsa zimachitika chizindikiro mu osiyanasiyana kuchokera 20 mpaka 100 kHz. Pa sekondale chomwecho kumulowetsa kupanga miyezo ya ukulu oscilloscope. Kukhazikitsa pamaso pa zimachitika kupotozedwa. Ngati iwo sali, kupanga mfundo za chipangizo yake.

Waveform kupotozedwa kuti windings propped. ali osavomerezeka yokonza makina onga paokha. Iwo anawaika zasayansi. Pali machenjerero ena kutsimikizira zimachitika tiransifoma, kumene anafufuza pamaso pa coils kumveka. sanamwe amasonyeza wonongeka chipangizo.

N'zothekanso kuyerekeza mawonekedwe a nyemba amaperekedwa ku pulayimale kumulowetsa ndi sekondale anatuluka. Kupatuka mu mawonekedwe analankhulanso za thiransifoma wonongeka.

windings angapo

Pakuti miyezo kulimbikira malekezero ufulu wa yogwirizana magetsi. Sankhani osachiritsika iliyonse ndipo anayeza wachibale kukana ena onse. Ndi bwino kulemba ubwino ndi chizindikiro anayesedwa nsonga.

Choncho tikhoza kudziwa mtundu wa kumulowetsa kugwirizana: ndi anapezazo pafupifupi, popanda iwo, ambiri kugwirizana mfundo. Nthawi zambiri ndi osiyana windings kugwirizana. kayesedwe ichitika yekha ndi mmodzi wa mawaya.

Ngati pali mfundo wamba, miyezo kukana pakati ochititsa onse. Awiri pakati kumulowetsa osachiritsika adzakhala ndi mfundo pakati mawaya atatu okha. mfundo zingapo opezeka mu tiransifoma lakonzedwa kuti ntchito Intaneti angapo chipembedzo cha 110 kapena 220 volts.

diagnostics mokoma

Tiziying'ung'uza pamene thiransifoma yachibadwa ngati chipangizo iyi yoyenera. Only sparking ndi kuthetheka amasonyeza vuto. Nthawi zambiri, ndi Kutentha coils - ichi ndi ntchito za masiku onse thiransifoma lapansi. Nthawi zambiri kumachitika mu kutsitsa zipangizo.

Kumveka akhoza analenga pamene akututuma thupi thiransifoma. Ndiye izo ziyenera kukhala zosavuta kukonza zinthu chimateteza. Ntchito windings zimasiyanasiyana kwambiri ndi kulankhula mwachisawawa omangika kapena zonyansa. mavuto ambiri anathana ndi kutenga chitsulo kuwala namukulunga ndi anapezazo watsopano.

Pamene kuyeza voteji ndipo panopa mfundo ayenera kuganizira yozungulira kutentha, kukula ndi chikhalidwe cha katundu. Control wa kotunga voteji n'kofunika nayenso. pafupipafupi mayeso kugwirizana chofunika. luso Asian ndi American anaikira 60 Hz, chifukwa mu mfundo otsika kwambiri linanena bungwe.

Tampering kugwirizana thiransifoma mwina chifukwa wonongeka chipangizo. Mulimonsemo osati kulumikizidwa ku windings wa DC voteji. The ankasinthana msanga oplavyatsya ayi. Zolondola miyezo ndi kugwirizana woyenera osati kupeza chifukwa cha kulephera, koma mwina kuchotsa izo mwanjira sabweretsa chisoni.
