Yechipiri mutoro wezvino transformer inokanganisa zvakananga kushanda kwayo.Kazhinji kutaura, kukura kwechipiri mutoro, kukanganisa kukuru kwe transformer.Chero bedzi mutoro wechipiri usingapfuure kukosha kwekugadzika kwemugadziri, mugadziri anofanirwa kuve nechokwadi chekuti chikanganiso chinogadzirwa neshanduko chiri mukati meyero yekurongeka kana mukati meiyo 10% yekukanganisa curve.Mukati.Nokudaro, panguva yekushandiswa kweshanduko yemazuva ano, yakatemerwa mutoro wechipiri uye chaiwo wechipiri mutoro unofanirwa kuzivikanwa.Chete kana iyo chaiyo yechipiri mutoro uri pasi peyakayerwa yechipiri mutoro unogona kukanganisa kuzadzisa zvinodiwa.
Kana kukanganisa kweshanduko yazvino kuchipfuura kukosha kwakatarwa kwemugadziri, ichava nemhedzisiro yakaipa pamidziyo yechipiri senge relay kuchengetedza uye metering zvishandiso.Matanho ekubhadhara anotorwa kana kukanganisa kweshanduko yemazuva ano inodarika kukosha kwakatarwa kwemugadziri.
(1) Wedzera nzvimbo ye-cross-sectional yetambo yechipiri kana kuderedza kureba kwetambo.Kuwedzera nzvimbo yemuchinjikwa-chikamu chechipiri tambo yechiuno chazvino kana kuderedza kureba kwetambo kunoderedza impedance yechipiri loop waya uye kuderedza mutoro wechipiri.
(2) Batanidza iyo yechipiri coil yeiyo backup yazvino transformer munhevedzano kupeta mutoro.Makoiri echipiri maviri mu-phase ikozvino transformers ane imwechete shanduko chiyero uye maitiro akafanana anoshandiswa munhevedzano.
(3) Wedzera chiyero chekushandura cheshanduro yemazuva ano kana kushandisa shanduro yemazuva ano ine yechipiri yakarongwa ikozvino ye1A.Maererano nenheyo yokuti kurasikirwa kwemutsara kwakaenzana nekona yemazuva ano, zvinogona kuonekwa kuti kurasikirwa kwemutsara kunova kuduku uye iyo impedance inobuda inova yakakura, saka mutoro wekutakura unosimbiswa.
(4) Deredza mutoro wechipiri.Sarudza relay ine yakakura yekumisikidza ikozvino zvakanyanya sezvinobvira, nekuti dhayamita yewaya relay coil ine yakakura yekumisikidza ikozvino yakakura uye nhamba yekutendeuka idiki, saka iyo impedance zvakare idiki;kana kushandura mutsara wekubatanidza weiyo relay coil kune inofananidzwa yekubatanidza, nekuti iyo impedance yeiyo yakatevedzana yekubatanidza Iyo impedance yakakura kupfuura iyo yakafanana kubatana;kana kushandisa microcomputer kudzivirira mudziyo kutsiva electromagnetic relay.
Muedzo wekudzivirira kupikisa kwezvino transformer
1. Chinangwa chebvunzo
Inogona kunyatso kuwana hurema hwekudzivirira, hwakadai sekunyorova, tsvina, kupinda, kuparara kwekudzivirira, nezvimwewo, pamwe nekupisa kwakanyanya uye kuchembera.Kuyera kudzivirira kwekudzivirira kwechidzitiro chekupedzisira kusvika pasi kunogona kunyatsoona kupinza kwemvura uye hunyoro hwehunyoro hweiyo capacitive ikozvino transformer.
2. Test scope
Kuyera kudzivirira kwekudzivirira kweyekutanga mhepo kune yechipiri mhepo uye casing, uye kudzivirira kwekudzivirira kweyechipiri mhepo inotenderera uye casing.
Kuyera kupikisa kwekudzivirira pakati pezvikamu zvekutanga zvekupeta, asi hazvidiwi kuyera pazvisingakwanisi kuyerwa nekuda kwezvikonzero zvemaitiro.
Kuyera kudzivirira kwekudzivirira kweyekupedzisira nhanho nhoo ye capacitive ikozvino transformer.

3. Kusarudzwa kwemichina
Edza kupikisa kwekudzivirira pakati pekudzivirira kukuru kweshanduko yemazuva ano, nhovo yekupedzisira, yechipiri mhepo uye pasi.Insulation resistance tester ye2500V uye pamusoro inofanirwa kushandiswa kugadzirisa kana handover bvunzo uye yekudzivirira bvunzo.
4. Dambudziko rekuongorora uye matanho ekudzora
kudzivirira kudonha kubva pakakwirira
Dzivirira kukuvara kubva kuzvinhu zvinodonha
kudzivirira kuvhunduka kwemagetsi
Usati wabvisa uye kubatanidza tambo yekuyedza, transformer iri pasi pekuyedzwa inofanirwa kuburitswa pasi zvachose kudzivirira yasara charge uye induced voltage kubva mukukuvadza vanhu uye kukanganisa mhedzisiro yekuyera.Iyo simbi casing yechiridzwa chekuyedza inofanira kudzika pasi, uye muyedzi ari kushandisa chiridzwa anofanira kumira pane insulating pad kana kupfeka insulating slash kushandisa chiridzwa.Mabatiro ebvunzo anofanirwa kurongeka nemunhu ari kutungamira, uye kuyambuka-kushanda hakubvumidzwe.
Misa nzvimbo dzekugara dzakavharika dzakatenderedza saiti yekuyedza, sungirira zviratidzo zve "stop, high voltage risk", uye simbisa kutarisa.Simbisa kutarisa uye shandisa nzira yekuimba iri kushanda.
5. Kugadzirira bvunzo isati yasvika
Nzwisisa mamiriro emunda uye bvunzo mamiriro emidziyo iri pasi pekuyedzwa.
Zadzisa bvunzo midziyo uye midziyo
Tora kuchengetedza uye hunyanzvi matanho panzvimbo yekuyedza
Iwo mabhokisi anoedza anofanirwa kutsanangura zvirimo zvebasa, zvikamu zvehupenyu, pa-saiti chengetedzo matanho, pane-saiti mashandiro enjodzi nzvimbo, uye kujekesa kupatsanurwa kwevashandi uye bvunzo maitiro.
6. Munda bvunzo matanho uye zvinodiwa
Tarisa iyo megohmmeter pachayo isati yaedzwa, isa iyo megohmmeter level yakasimba, yekutanga pfupi-circuit bvunzo uyezve yakavhurika-yedunhu bvunzo, kana yakabatana nemagetsi eiyo yakagadziriswa voltage megohmmeter, waya yeUno ichaita pfupi-circuit "L" uye “E”” terminal, chiratidzo chinofanira kunge chiri zero; kana chabatidzwa, kana simba rikabatidzwa kana kuti kasi yakayerwa inoratidzwa nemamegohms, chiratidzo chinofanira kunge chiri “∞”. Pakuisa waya, tanga wabatanidza terminal yepasi wobva wabatanidza iyo high voltage terminal.
Iyo terminal "E" pane megohmmeter ndiyo yepasi terminal yechinhu chebvunzo, inova danda rakanaka, uye "L" ndiyo yakakwira-voltage terminal yechigadzirwa chebvunzo, inova danda risina kunaka."G" yakabatana kune shield terminal, inova danda rakashata.
7. Insulation resistance test
Edza kudzivirira kwekudzivirira kwekutanga mhepo yekushandura ikozvino kune yechipiri mhepo uye goko
Edza kudzivirira kwekudzivirira pakati pechipiri mhepo yekushandura ikozvino uye pasi
Kuyera kupikisa kwekudzivirira kwechidzitiro chekupedzisira chezvino transformer
Kuyera kudzivirira kwekudzivirira kwekutanga mhepo
Iyo yekutanga windings P1 uye P2 yezvino transformer ipfupi-inotenderera newaya mapfupi, ese echipiri mhepo inotenderera ipfupi-inotenderedzwa pasi, uye yekupedzisira nhovo ipfupi-inotenderedzwa pasi.(Kana nzvimbo ye transformer ichinyanya kurema, mhete yekudzivirira inofanira kuiswa uye yakabatana ne "G" terminal ye megger ine insulated wire.)
Iyo "L" terminal yeyakakwira-voltage insulation tester yakabatana kune yekutanga mhepo P1 uye P2 materminal ezvino transformer kana waya pfupi, uye "E" terminal inodzika.
Mushure mekutarisa wiring, tinya bhatani re "Tanga", uye mita inotanga kushanda.Mushure meminiti 1, kukosha kwekudzivirira kwekudzivirira kuchanyorwa.Mushure mekunge bvunzo yapera, mita inofanira kubviswa kubva pamuenzaniso, wobva wadzvanya bhatani rekuti "mira" kuti utangezve mita.
Pakupedzisira, buritsa chikamu chekuyedza chezvino transformer.
