Product features and Principle

Iyo LCWD-35 yazvino transformer idiki, diki muhukuru uye yakareruka muhuremu.Iyo yekumusoro hafu ndiyo yekutanga mhepo, hafu yepasi ndiyo yechipiri mhepo, iyo gwenzi yakamisikidzwa pachigadziko, kumusoro kwebhuranzi rakashongedzerwa nemafuta anochengetedza, iyo yekutanga mhepo inotungamirwa kubva kumativi ese emadziro emadziro, uye yekutanga terminal yakanyorwa P1 A diki porcelain sleeve inoshandiswa insulate madziro ekhabhineti, uye yekupedzisira P2 yakabatana zvakananga kumadziro ekhabhineti.Kumberi kwemuchengetedzi wemafuta kune magaji emafuta anoratidza kupisa kwakasiyana.

Musimboti:
Mune mitsetse yekugadzira magetsi, substation, kuendesa, kugovera uye kushandiswa, ikozvino inosiyana zvakanyanya, kubva kune mashoma amperes kusvika makumi ezviuru zveamperes.Kuti ifambise kuyerwa, kudzivirira uye kutonga, inoda kushandurwa kuita inofanana ikozvino.Mukuwedzera, magetsi pamutsara anowanzo kukwirira, seyero yakananga, iyo ine ngozi zvikuru.Ikozvino transformer inobata basa rekushandura ikozvino uye kuparadzaniswa kwemagetsi.
Kune pointer-type ammeters, mazhinji echipiri mafungu eazvino anoshandura ari muampere level (senge 5A, nezvimwewo).Zvezviridzwa zvedhijitari, chiratidzo chesampled chinowanzo pamilliamp level (0-5V, 4-20mA, nezvimwewo).Yechipiri ikozvino yeminiature yazvino transformer is milliampere, iyo inonyanya kuita sebhiriji pakati peiyo huru transformer uye sampling.
Miniature ikozvino transformers inonziwo "instrument current transformers".("Instrument current transformer" ine chirevo chekuti imulti-current ratio precision current transformer inoshandiswa murabhoritari, iyo inowanzo shandiswa kuwedzera chiridzwa.)
Zvakafanana neshanduro, shanduri yazvino inoshandawo zvinoenderana nemusimboti we electromagnetic induction.Iyo transformer inoshandura voltage uye ikozvino transformer inoshandura ikozvino.Kupeta kweshanduko yazvino yakabatana kune yakayerwa ikozvino (nhamba yekutendeuka ndiN1) inonzi yekutanga mhepo (kana yekutanga mhepo, yekutanga mhepo);mhepo yakabatana nechiridzwa chekuyeresa (nhamba yekutendeuka ndiN2) inonzi yechipiri mhepo (kana yechipiri mhepo).mhepo, mhepo yechipiri).
Chiyero chemazuva ano chepakutanga chinoputika ikozvino I1 kusvika kune yechipiri mhepo I2 yeshanduro yezvino inonzi inonzi chaiyo ikozvino chiyero K. Chiyero chemazuva ano cheshanduro yemazuva ano kana ichishanda pasi pemazuva ano inonzi inonzi rated current ratio yezvino transformer. , yakataurwa naKn.
Kn=I1n/I2n
Basa rekushandura ikozvino (CT yenguva pfupi) ndeyekushandura ikozvino yekutanga nehuwandu hukuru mune yechipiri ikozvino ine diki kukosha kuburikidza neimwe shanduko yekuchinja, iyo inoshandiswa pakudzivirira, kuyerwa uye zvimwe zvinangwa.Semuenzaniso, shanduko yemazuva ano ine chiyero che400/5 inogona kushandura ikozvino chaiyo ye400A kuita ikozvino ye5A.

Transformer Dambudziko Kubata uye kuronga kuronga

Kubata Matambudziko ane chekuita neTransformer:
Ikozvino kutadza kwetransformer kunowanzo kuperekedzwa nemanzwi uye zvimwe zviitiko.Kana dunhu rechipiri richinge ravhurwa kamwe kamwe, mukana wepamusoro wakakonzerwa unogadzirwa mune yechipiri coil, uye kukosha kwayo kwepamusoro kunogona kusvika kupfuura zviuru zvinoverengeka volts, izvo zvinoisa pangozi hupenyu hwevashandi uye kuchengetedzeka kwemidziyo padunhu rechipiri, uye high voltage inogona kukonzera arc moto.Panguva imwecheteyo, nekuda kwekuwedzera kwakanyanya kweiyo magnetic flux musimbi core, inosvika kune yakakwirira saturation state.Iko kurasikirwa kwepakati uye kupisa kwakakomba, izvo zvinogona kukuvadza rheological yechipiri mhepo.Panguva ino, iyo isiri-sinusoidal wave inokonzerwa nekuwedzera kweiyo magnetic flux density, iyo inoita kuti kuzunguzika kwesilicon simbi sheet kusaenzana zvakanyanya, zvichikonzera ruzha rukuru.
1. Kubata kwezvino transformer munharaunda yakazaruka Kana kukanganisa kwakadaro kukaitika, mutoro unofanirwa kuchengetwa usina kuchinjwa, chigadziro chekudzivirira chinogona kunge chisina kushanda chinofanira kuvharwa, uye vashandi vakakodzera vanofanira kuziviswa kuti vabvise nokukurumidza.
2. Kurapa kwezvino transformer yechipiri yedunhu disconnection (yakazaruka redunhu) 1. Chiitiko chisina kujairika:
a.Chiratidzo cheammeter chinodonha kusvika zero, chiratidzo chemagetsi anoshanda uye anogadzirisa magetsi anoderera kana oscillates, uye watt-awa mita inotenderera zvishoma nezvishoma kana kumira.
b.Differential disconnection light plate yambiro.
c.Ikozvino transformer inoita ruzha rusina kujairika kana kuburitsa kupisa, kuputa kana kubuda kubva kune yechipiri terminals, sparks, nezvimwe.
d.Iyo relay yekudzivirira mudziyo inoramba kuita, kana kusashanda (ichi chiitiko chinongowanikwa kana muparadzi wedunhu afamba nekukanganisa kana kuramba kutsika uye kukonzera rwendo rwe leapfrog).
2. Kubata kunze:
a.Pakarepo shuma chiratidzo kuhurongwa hwacho.
b.Zvinoenderana nechiitiko ichi, tongai kana ikozvino shanduri yeyero yedunhu kana yekudzivirira yedunhu yakavhurika.Kudzivirirwa kwezvidziviriro zvinogona kukonzera mashandiro asina kunaka kunofanirwa kutariswa kusati kwaraswa.
c.Paunenge uchitarisa chechipiri chedunhu reshanduko yazvino, iwe unofanirwa kumira pane insulating pad, teerera kune wega kuchengetedzwa, uye shandisa akakodzera ekudzivirira maturusi.
d.Apo chikamu chechipiri cheshanduro yemazuva ano yakazaruka kuti iite moto, simba rinofanira kubviswa pakutanga, uye ipapo moto unofanira kudzima nemucheka wakaoma weasbestos kana moto wakaoma.
3. Ikozvino transformer body kukanganisa Kana ikozvino transformer kukanganisa ine imwe yeanotevera mamiriro, inofanira kumiswa nekukasira:
a.Pane ruzha rusina kujairika uye kupisa mukati, kuchiperekedzwa nehutsi uye kunhuwa kwakatsva.b.Yakakomba mafuta kuvuza, yakakuvadzwa porcelain kana discharge phenomenon.
c.Fuel jekiseni moto kana glue kuyerera phenomenon.
d.Kurebesa kwesimbi expander zvakanyanya kudarika kukosha kwakatarwa pakupisa kwe ambient.

Odha chirongwa:
1. Ipa wiring scheme diagram, application uye system diagram, rated voltage, rated current, etc.
2. Zvinodiwa zvekutonga, kuyerwa nekudzivirira mabasa uye zvimwe zvekuvhara uye otomatiki zvishandiso.
3. Kana iyo transformer inoshandiswa mumamiriro ezvinhu anokosha ezvakatipoteredza, inofanira kutsanangurwa zvakadzama paunenge uchirayira.
4. Kana zvimwe kana zvimwe zvishongedzo uye zvikamu zvakasara zvichidikanwa, rudzi uye huwandu hunofanirwa kutaurwa.
