Iska na ƙananan wutar lantarki na mitar masana'antu

Daban-daban na kayan aikin gida, masana'antumitar masu canza wuta, ko sun tsara nasu iska, ko gyara wutar lantarki mai ƙonewa, suna da hannu a cikin wani ɓangare na lissafi mai sauƙi, litattafai akan tsarin, ko da yake m, amma aikace-aikacen aikace-aikace na rikitarwa, ba dace sosai ba.Wannan labarin yana gabatar da ƙididdiga mai amfani na ma'auni na ma'auni.

1. Zaɓin ainihin ƙarfe

Bisa ga nasu ikon bukatar zabar daidai core ne mataki na farko a winding na'urar wuta. Idan zaɓin baƙin ƙarfe (silin karfe takarda) ya yi girma sosai, zai haifar da karuwa a cikin girman mai canzawa, farashin mafi girma, amma ƙananan ƙarfe ya yi ƙanƙara, zai ƙara asarar mai canzawa, yayin da damar. don ɗaukar kaya ya zama matalauta.

Keɓance 12V 24v Transformer

Domin sanin girman da baƙin ƙarfe core, abu na farko da za a lissafta ainihin ikon amfani da gidan wuta na biyu, wanda shi ne daidai da transformer secondary winding ƙarfin lantarki, jimlar samfurin na load halin yanzu. Idan mai gyaran wutar lantarki ne mai cikakken igiyar ruwa, yakamata a lissafta shi a matsayin 1/2 na wutar lantarki na biyu. Yin amfani da wutar lantarki na biyu don haɗa wutar lantarki da kanta asara, wato wutar lantarki ta farko ta bayyana.

Ƙarfin wutar lantarki na gaba ɗaya a cikin 10w a ƙasa da gidan wuta, asarar wutar lantarki na biyu na iya zama har zuwa 30 ~ 50% na ainihin amfani da wutar lantarki, ingancinsa shine kawai 50 ~ 70%. Ikon iska na biyu a cikin 30 w ƙasa asarar kusan 20 ~ 30%, 50 w ƙasa asarar kusan 15 ~ 20%, 100 w ƙasa asarar kusan 10 ~ 15%, 100 w sama da asarar kusan 10% ƙasa, na sama Ma'aunin hasara shine game da na'ura mai ba da wutar lantarki na yau da kullun. Idan aka bi odar taranfoma na nau'in R, da na'urar c-type da kuma toroidal transformer, ma'aunin asara yana raguwa bi da bi.

2. Lissafin juyi a kowace volt

Bayan zaɓar ainihin s. Sannan tantance adadin juye-juye a kowace volt, domin iskar da wutar lantarki yana da madaidaicin motsin motsi. Ƙimar da aka saba amfani da ita: N = (40 ~ 55)/S, N shine adadin juyi a kowace volt.

Bisa ga daban-daban ingancin silicon karfe takardar selection coefficient 40 ~ 55. more ci-gaba high silicon karfe, tare da ido don tsayar da surface na Sikeli na crystallization. Kuma musamman gaggautsa, kawai 1 zuwa 2 sau cewa karya, karya a m, da coefficient aka dauka a matsayin 40. Idan silicon karfe takardar surface ne mai tsabta, lankwasawa 4 zuwa 5 sau ne har yanzu ba sauki karya, sashe ga m. madaidaiciyar layi, ana ɗaukar ƙididdiga fiye da 50.

Nemo adadin juyi a kowace volt wanda aka ninka da 220V wato juyi na farko, wanda aka ninka da adadin buƙatun ƙarfin lantarki na sakandare wanda shine juyi na biyu. Saboda waya yana da juriya, halin yanzu yana gudana ta hanyar raguwar ƙarfin lantarki, juyawa na biyu ya kamata a ƙara da 5 ~ lO% (bisa ga zaɓi na yanzu na kaya, ana iya ƙara yawan halin yanzu ta mafi girma).

3. Zaɓin diamita na waya

Dangane da girman iskar nauyin halin yanzu, zaɓi diamita daban-daban na enaled waya. Za a iya amfani da dabarar ƙwaƙƙwaran ƙira don ganowa:

4. Hanyoyin Iska da Kariya

Don haka, a zamanin yau, ƙarfin rufewa na enameled waya ya inganta sosai. Dominkananan wutar lantarkia kusa da 50W, yawanci muna tafiya tare da kwarangwal ɗin filastik mai ɗaukar harshen wuta kuma muna tara iska. Kawai tabbatar da yin amfani da waya mai ƙarfi mai ƙarfi, kuma lokacin da kake jujjuya shi, kiyaye duk abin da aka jera layi ta layi-ba a yarda da babban tazarar diagonal! Wannan yana taimakawa wajen guje wa ƙara bambancin wutar lantarki tsakanin wayoyi. Ga masu taswira sama da 50W, tunda akwai ƙarancin juyi a kowace volt, bambancin ƙarfin lantarki tsakanin wayoyi yana ƙaruwa. Zai fi kyau a ajiye takarda mai rufewa (kamar takarda mai kauri 0.05mm ko takarda kraft) ga kowane Layer yayin da kuke iska.

Tabbas kuna son hana duk wani yadudduka na sama daga zamewa cikin ƙananan! Ya kamata rufin da ke tsakanin windings ya dogara da nawa irin ƙarfin lantarki da kuke mu'amala da su. Tsakanin matakan farko, nufin aƙalla yadudduka huɗu na takarda na kebul na 0.1mm — tsallake amfani da tef ɗin manne kai anan! Idan ƙaramin injin ku yana da fiye da ƙungiyoyi biyu na iska na biyu da aka tattara tare, tabbatar da ƙara yadudduka biyu na rufin takardar kebul tsakanin kowace ƙungiya kuma. Kuma idan wannan transformer yana shiga cikin kayan sauti ko na gani? Kar a manta kun haɗa wasu abubuwan kariya na lantarki a cikin waɗancan saitin Layer Layer. Bayan kun yi duk abin da ke motsawa, kula lokacin shigar da zanen karfe na silicon - suna buƙatar dacewa da kyau don kada ku sami hayaniyar lantarki ta lalata abubuwa.

Lokacin da kake saka waɗannan ƴan kaɗan na ƙarshe (kimanin hudu ko biyar), yi daga tsakiya don kada ku lalata kowane nau'in waya a hanya. Sa'an nan kuma mu bushe shi mu tsoma shi a cikin fenti daga baya! Don masu canji a ƙarƙashin 50W, zaku iya amfani da hanyar bushewa ta endothermic: gajeriyar kewaya duk windings na biyu da farko sannan ku haɗa kwan fitila (60 ~ 100W / 220V) a cikin jerin tare da wutar lantarki ta yadda ta sami kanta ta atomatik. Babban kwan fitila, mafi girman zafin jiki, amma a cikin rufaffiyar yanayi, ta yadda zafin jiki ya kasance ƙasa da digiri 80 ya fi aminci.
