Yaya Ake Samunin Ma'ajin Na Farko

Idan aka samu transformer na bayani, ka ga tanki na steel, kadan bushings, da nameplate. Wanda ba ka ga shi shine chainin mai tsari ta yawa wanda ke cikin karama, cikin rarraba, da kuma cikin tsarin da aka gudanar da su don ƙara abubuwan da suka zama maki mai yiwu wanda zai yi ayyuka akan daga zuwa zuwa.

Wadanda transformer biyu da suka da kudin sama suna iya farko a cikin loss, ƙarfi na yaki, tsanani, da zaman lafiya. Farko akwai ne kamar yadda aka yi amfani da asalin yin wani abu.

A Jiangsu Zhongmeng Electric, muna sanadi da wadanda abubuwan da suka dace don 35kV—kamar transformer na daji da wadanda substation na gaba. A wannan rubutu, muna buƙata gida mu da shi da muna nufin mu bayyana duk wani hanyar da aka yi a yin transformer, don haka za ka ga abubuwan da suka dace don abin da ka sake.

Transformer ba abu ne da aka tashi daga wani nau'in abubuwa. Ya zama abu ne da aka yi daga wani nau'in asalin da suka dace da saushe.

Yi karin cuttin na silicon steel ya zama cause na no-load loss.

Yi karin winding da ke kara da ƙarfi ya zama cause na load loss da ƙarfi na yaki.

Yi karin drying da ba suka dace ya zama cause na moisture a cikin insulation, wanda ya zama cause na partial discharge.

Yi karin oil treatment da ba suka dace ya zama cause na karamin insulation strength da karamin cooling performance.

Wani kalmi na gaba, kyautar transformer ba a sanya shi ne—amma a cika shi, kuma kuma.

2.1 Sanya da Tattaunawa na Abubuwan da Su Ka Zo

Kowa yake fito daga abubuwan da suka zo.

Mu sanya da tattaunawa:

Shafuka na silikon na tsaki – don tattaunawa na kafa

Copper ko aluminum na kafa – don tattaunawa

Insulation materials – kirti, pressboard, da cylinders na tattaunawa

Abu na transformer – don ƙarfi da saukin yin kariya

Shafukan Fulani – don tank

Kullum batch an yi amfani da ita don duba tsawon, kariya, ƙarfin kariya, da sauran bayanai masu muhimmi. Wani transformer zai iya zama babba kamar abubuwan da ake sanya a cikin sa.

2.2 Tsarin Tsarin Kafa

Kafa shi ne tsarin maganin na transformer.

Sukurun muhimmi suna haɗa da:

Sauke shigar da sheets na silicon steel zuwa ƙwayoyin da kuma gaba'ain da suka bukata

Laminating shigar da sheets a tsari mai kyau

Junkada kafa don kara ta fadada da kara ta dace

Maimakon Kafin Zaiyi kullun da ke kare kari kafin kari na laminations

Kwalitas ta core ya zama tushen no-load loss da noise level. Core mai kyau ya gudan yana gudan da saukar da kuma yana gudan da karami.

2.3 Tsarin Tsarin Winding

Winding suna ne tsarin elektriki na transformer.

Mun tsara:

Winding na high-voltage

Winding na low-voltage

A cikin wani lokaci, winding suka iya zama cylindrical, disc-type, ko foil-type. A lokacin winding, mu kare:

Tension na winding

Arrangement na turn

Kulobin insulation a tsakanin karama da karama

Amfani da Rubutun

Kwalitas na winding tana iya fuskanta load loss, temperature rise, da short-circuit withstand capability.

2.4 Koma da Coil Assembly

Idan koma da winding sun kashe, suna kawo su cikin body na transformer.

Wannan yadda yake kuma:

Kawo winding cikin koma

Sanya kulobi na insulation da spacers

Kawo leads da taps

Sanya assembly don ayyukan na gaba

Kowace kariya da kowace yadda ake tsara shi ke taimaka. Wani rarraba mai yawa zai iya saba waɗanda suka ƙare da kariya ko ƙarshen kariya a lokacin amfani.

2.5 Kusantarwa da Tashin Kafin Daga Zazzau

Kusantarwa shi ne daga cikin abubuwan da suka yi amfani da kariya ta transformer.

Don kusantar kusantarwa, mu amfani da:

Tasirin dahuwa

Kusantarwa ta zazzau

Jirin transformer an zauna shi a cikin chamber na zazzau kuma an kusantar shi a tsakanin yadda yake da zazzau da yadda yake da hanyar kusantarwa. Wannan babban yadda yake da amfani ga:

Karamin kuskuren na kofin

Tatsuniya dielectric

Yadda yake da amfani da kariya ta kusantarwa

Taimakon tsawon zaman

2.6 Kusantarwa ta zazzau da kafa zazzau a cikin transformer

Zazzau ta transformer tana ba da kariya kuma tana kawo kusantarwa.

A baya kafa, zazzau ta:

Kusantar

Ya ƙara kuma ya ƙare gaba daya

Ya ƙara ruwa

Sau da yawa, zaiyi shigarwa na maya a cikin tanki ta hanyar vacuum. Wannan yana kare wa kafin koyaushe da ruwa a cikin sistema na kare ruwa. Mayan da suka dace da sauyi da suka dace da ruwa suna da mahimmanci don amfani da safe.

2.7 Kammalawa Na Gaba Daya Da Kandakarwa

Bayan shigarwa na maya, transformer zai kammala da abubuwan da suka gabata:

Tanki da kandakarwa

Kasa

Tap changer

Gurbin Fadawa

Matsayin tsarin yadda zai yi maimaita

Shafin suna

Duk wani kandakarwa mai kare ruwa ana sanya shi da kyau. Mu amfani da imtihanin kare ruwa don ganin cewa ba kare ruwa ba a cikin tanki wajen amfani da normal da wadanda ba su normal ba.

2.8 Imtihanin Faburki

Babu transformer din da suka fito daga factory mun ya kuma ba tare da yin tests guda biyu ba.

Kamar yadda ake yi amma, sun haɗa:

Test na ratio

Ganin DC resistance

Test na insulation resistance

Dielectric withstand test

Ganin no-load loss da load loss

Test na impedance voltage

Tare da abin da mutum ya so, mu kuma yi:

Test na temperature rise

Tasmiyar kusanci na baya

Tasmiyar tashin yadda

Kamar yadda ake bayyana, ba za a ba transformer da ƙarshen bayanin al'umma na kasuwa ko za a sanya shi don samun kudin gaba mai zuwa ba ne amma idan suka gabata dukkanin tasmiyoyi da suka duba bayanan su.

A cikin duk wadannan tsari, wadanda suka zama muhimmanci sosai su ne:

Wadannan ba su kuma ayyukan fasaha ce. Su ne daga cikin wadanda yadda amfani da koyon gaba, tsarin, da kayayyadi suka samu farko.

A yanzu, mun sanya sarrafa S14 600 kVA 10/0.4 kV na transformer mai zuba a kan ruwa ga abokan ciniki. A lokacin tashin nisba na kasar, mun gano cewa transformer daya ya kawo tashin nisba ta fi kyauta, kuma tsinkin na fuskantar ya fi yawa.

Bayan sanin bayanin masu halarta, mun gano sababin: adadin kudun da aka sanya suka dace ba. Wannan matsala ba ta ziyarce kudin kuma, amma ta kawo kariya na kai tsaye.

Bayan haka, mun saita tsarin tashin a lokacin sanya. Wannan ya taimaka min kara yadda wannan matsala za ta faru kafin.

Don haka, kowanne ayyuka na sanyawa na transformer ke da mahimmanci. Mu ya tsaya kudin kowanne ayyuka.

Transformer na kai tsaye ba abubuwa ta hanyar karkara ce. Shii ne nata daga cikin dukkanin ayyukan da suka biyu, dukkanin tashin da suka biyu, da koyon sanyawa na shekara manya.

A Jiangsu Unita Electric, mu sani cewa ƙarfin ƙarfi na amfani da kuma ƙarfin ƙarfi na mutane ne ke zama ƙarfin ƙarfi na amfani da kuma ƙarfin ƙarfi na mutane. Wanda shine saboda mun gudan yadda muna iya tafiyar gida na mu, ganin ƙarfin ƙarfi, kuma duba ƙarfin ƙarfi na amfani da kuma ƙarfin ƙarfi na amfani da kuma ƙarfin ƙarfi.

Idan kana zaune transformer, ba kuka zaune hanya ce. Kuka zaune ƙarfin ƙarfi na amfani da kuma ƙarfin ƙarfi.
