Nauyin juriya yana nufin adadin wutar lantarki 1 (cos = 1) lokacin da kawai aka yi amfani da nauyin juriya.Alamar da aka ƙididdige ta sauya tana nuna ƙarfin halin yanzu lokacin da ake amfani da ac.Gabaɗaya ana amfani da su a cikin majalisar gwaji na canji, nemi UL.CQC da sauran takaddun samfuran, jikin takaddun shaida wanda aka keɓe azaman ƙarfin juriya, nauyin juriya gabaɗaya yana nufin nauyin 100% iko.Ta wannan hanyar kawai za'a iya ba da ainihin ma'auni na kayan sauya kayan aiki.

Aikace-aikacen sauyawa a cikin nauyin juriya shine: tanda, murhun lantarki, yin zafi da sauri, injin ruwa da sauransu yakamata su kasance cikin nauyin juriya.

DC kaya

Ƙarƙashin nauyin dc, daban-daban da ac, tsawon lokacin arc ya fi tsayi a ƙarƙashin irin ƙarfin lantarki ɗaya saboda jagorancin halin yanzu yana da tsayi.Ana amfani da shi sau da yawa a cikin samfuran lantarki a kan jirgi, kamar injin tsabtace kan jirgi, famfon iska a kan jirgi, da dai sauransu. Hanyar lissafin analog ɗin lodin dc shine: 14VDC=115VAC.28VDC=250VAC, gabaɗaya lissafin analog ɗin da ya fi fahimta shine kamar haka, wannan ba ƙa'ida ce mai wahala ba, amma a cikin aikace-aikacen masana'antar canzawa, ƙirar ƙididdiga, kamar 3A 14VDC.Load dc yana kama da 3A 115VAC ac load.Duk da haka, a ƙarƙashin ƙimar halin yanzu da ƙarfin lantarki iri ɗaya, lalacewar dc lodi akan lambar sadarwa ya fi na ac.

Layin fitilar wuta

Lokacin da fitilar ta kunna, saita maɓallin kunnawa, saboda saurin motsi na yanzu shine sau 10 zuwa 15 na halin yanzu na yau da kullun, mannewar lamba na iya faruwa, da fatan za a yi la'akari da canjin halin yanzu lokacin kunna canjin.

Ana amfani da maɓalli don walƙiya mataki, hasken Laser, da fitillu.Misali, ƙimar haske na yanzu shine 5A 220VAC.A lokacin da hasken ya fara, ƙarfin halin yanzu zai iya kaiwa zuwa 60A.Ƙarƙashin irin wannan babban nauyin, idan lambar sadarwa ta ed ba daidai ba, ko kuma rushewar wutar lantarki ba ta da ƙarfi, yana da sauƙi don haifar da mannewar lambar sadarwa, wanda ba za a iya cirewa ba.

Load ɗin shigarwa

Game da inductive load relays, solenoids, buzzers, da dai sauransu, za a haifar da baka ta hanyar yuwuwar farawa, wanda zai iya haifar da gazawar lamba.Sabili da haka, ana bada shawara don dacewa da walƙiya don kawar da baka.

Nauyin inductive nauyi ne na gama gari a cikin sauya wutar lantarki, wanda zai haifar da tashin hankali na yanzu fiye da na yau da kullun na yau da kullun, kuma ƙarfin halin yanzu yana iya kaiwa sau 8 zuwa 10 cikin sauƙi na halin yanzu.Lokacin da na'urar kunna kayan aikin inductive ta kunna, inductor ko taswira za su fahimci jujjuyawar wutar lantarki a cikin kewaye.Wannan ƙarfin lantarki yana yin kowane canji a halin yanzu na kewaye kuma yana iya kaiwa ɗaruruwan volts.Irin wannan babban ƙarfin lantarki zai iya hana lalatawar lambobi na arc arc, suna taka rawa wajen tsaftace kai.A karkashin yanayi guda.Load ɗin inductive dc ya fi lalata ga masu canza lambobi, don haka nauyin inductive dc ya kamata a ed a matsayi mafi girma fiye da ac.Motar lantarki, injin walda lantarki, firiji, kwandishan, fanka na lantarki, kaho mai iyaka, rawar lantarki da sauransu suna ɗaukar nauyi.

Motoci lodi

Lokacin da aka kunna motar, farkon halin yanzu yana gudana ta shine sau 3 ~ 8 na halin yanzu na yau da kullun, don haka mannewar lamba na iya faruwa.Nau'in motar ya bambanta, amma abin da ke gudana a halin yanzu ya ninka sau da yawa na halin yanzu, don haka da fatan za a koma ga ƙimar da aka nuna a cikin tebur ɗin da ke ƙasa lokacin kunna canjin.

Bugu da ƙari, lokacin da aka juya motar a cikin juyawa, yana da muhimmanci a yi la'akari da cewa ya kamata a kauce wa yawan halin yanzu (farawa na yanzu + baya farawa na yanzu) lokacin da ake amfani da maɓallin kunnawa.

Nau'in motar

A cikin yanayin jujjuyawar jujjuyawar yayin juyawa, abin da ke gudana a halin yanzu yana kusan ninki biyu fiye da lokacin farawa.Bugu da ƙari, ana amfani da shi don ɗaukar nauyi tare da yanayin canzawa, kamar aikin juyawa na motsa jiki, ko sauyawar heteropolar, da dai sauransu Saboda tasirin jinkirin lokaci, arc short circuit (gajeren kewayawa) na iya faruwa a tsakanin sandunan lokacin sauyawa.

Akwai rashin fahimtar juna tsakanin karfin dawaki da lodin mota.A gaskiya ma, lokacin da aka yi wa lakabin sauya harsashi, ana ganin sau da yawa cewa 30A 250VAC yana nufin kaya a farkon relay.

1/2HP shine manufar iko!Kusan 1250 w.

1 doki (HP) = 2500W, wanda aka bayyana shi azaman 2499W a Japan, kuma an ƙididdige shi bisa ga ƙimar ƙarfin kuzarin EER.

1 horsepower = 735W, an ayyana doki a matsayin adadin ƙarfin da aka samar ta hanyar shigar da ƙarfin doki 1.Akwai tambaya game da ƙididdigewa, wanda shine 3.4 bisa ga ka'idar Jafananci, kuma 3.4 shine mafi ƙarancin ƙarfin kuzarin da yakamata a karɓa.

Don haka doki 1 = 735*3.4=2499W

Capacitor lodi

Karkashin nauyin fitilun mercury, fitila mai kyalli da da'irar capacitor, lokacin da aka haɗa da'irar juyawa, zai gudana ta cikin babban ƙarfin halin yanzu, wani lokacin ya kai sau 100 na ƙarfin halin yanzu.Don haka, da fatan za a yi amfani da ainihin nauyin don auna ƙimar canjin sa kuma tabbatar da ko ana amfani da shi a cikin kewayon ba tare da ƙetare ƙimar halin yanzu ba, sannan amfani da shi bayan amfani da ainihin nauyin don tabbatarwa.Ya kamata na'urorin lantarki irin su talabijin da kwamfutoci su kasance masu ɗaukar nauyi.

Mini Load

Canja lambobin sadarwa da aka yi amfani da su a fagen ƙananan kaya, idan ba a yi musu lakabi na musamman ba, galoli ne na azurfa ko azurfa.Sabili da haka, saboda canjin lokaci da kuma tasirin yanayin waje, yanayin hulɗar yana da haɗari ga vulcanization kuma ƙaddamarwa na iya zama maras tabbas.Don wannan dalili, a cikin amfani da ƙaramin halin yanzu, yi amfani da ƙarancin mitar, da fatan za a yi amfani da plating na gwal ko Au na samfuran masu zuwa.

Misali, samfurin HONYONE's TS jerin tare da maɓallin taɓa haske.Maballin canza samfurin PB06, jerin PB26, da dai sauransu. Yana nufin mafi ƙarancin halin yanzu a ƙarƙashin 6mA, ƙaramin ƙarfin lantarki a ƙarƙashin 3V, mai kunnawa kawai yana taka rawa na siginar faɗakarwa, nauyin da aka sanya akan mai kunnawa za a iya watsi da shi, amma wannan shine wannan. irin ƙananan ƙananan maɓalli, shine masana'antar canzawa ita ce mafi wuyar sarrafawa.HONYONE ya tattara fiye da shekaru 20 na masana'antu da ƙwarewar bincike, kuma ya kai matsayi na gaba a fagen canjin ƙananan kaya.
