Wiring Principle:

Zvigadzirwa zvechigadzirwa uye chiyero chekushandiswa

JLSZV35 yakatevedzana matatu-chikamu chekunze, yakaoma-mhando, yakakura-mutoro yakasanganiswa transformer (ine metering bhokisi), zvikamu zvechikamu chechigadzirwa zvakavharidzirwa nekunze epoxy resin casting, uye zvikamu zveyuniti zvinounganidzwa kuita chimwe (kana kupatsanurwa) chimiro, kuitira kuti chigadzirwa ive Iine zvakanakira anti-ultraviolet, anti-aging, anti-raiin nezvimwe zvakadaro.Chigadzirwa chacho chinogona kushandiswa kune imwechete, kaviri uye katatu ikozvino chiyero, uye iyo yakakwira chaiyo ye0.2S inovimbisa kuyerwa kwakaringana pasi pemutoro wakakura.Kaviri uye katatu zvazvino zviyero zvinotora yechipiri tapi chimiro.
Matatu-chikamu maviri-element simba metering bhokisi (musanganiswa transformer)
Iwo matatu-phase matatu-waya akasanganiswa transformer (mbiri-element) ine maviri-single-phase voltage transformers (PT) uye maviri emazuva ano transformer (CT).Ose ari maviri PT uye CT ari emagetsi, uye iwo maviri PT windings akabatana neV/V.Chigadziro chekuyera chetatu-chikamu chinoumbwa, uye mapeji ekutanga emaCTs maviri akabatanidzwa munhevedzano nezvikamu A uye C zvegridhi zvakateerana.Pane siruuru yepasi yakakandwa pabhureki rekusungirira pasi.
Matatu-chikamu matatu-element simba metering bhokisi (musanganiswa transformer)
Three-phase three-element power metering box (combined transformer) Y/Y 0 yekubatanidza metering bhokisi chigadzirwa chechizvarwa chitsva chakagadziridzwa pahwaro hwematatu-chikamu maviri-element VV kubatana, nekuti nekuenderera mberi kwenharaunda yanhasi, simba. grid Mamiriro ezvinhu emutoro ari kuramba achikura uye achichinja, semuenzaniso: imwe-chikamu kugadziridzwa kwemagetsi njanji, kunyungudutswa kwechoto chemagetsi, kugadzirisa uye electrolysis, nezvimwewo, pamwe nekuwirirana mugedhi remagetsi, uye kusaenzana kwechikamu chemitoro inogona kukonzera. kutevedzana kwakashata kana maharmonics mukubatana kweV/V.Chiyero chacho hachina kururama nekuti wave hauna chiteshi (maererano nechiyero chaicho, Y/Y 0 yekubatanidza nzira inogona kuwedzera mari ne3% -15%), saka fekitori yedu ichangobva kugadzira Y/Y 0 nzira yekubatanidza ye. iyo metering box kuti ienderane kune yakaoma mamiriro ekushanda.Inogona kuvimbisa kuyerwa kwakaringana uye kubatirana pamwe neshanduko yazvino yesimba remagetsi manejimendi.Bhokisi remamita rine hunhu hwekuyera kuchinjika.Semuenzaniso, iyo single-phase watt-awa mita inogona kutarisa kushanda kweyega yega chikamu mutoro kuitira kuti uwane matambudziko nenguva.Kana mutoro ukachinja zvakanyanya, ndapota shandisa iyo S-kirasi (chiyero chechiyero kubva pa1% -120% yeyakayerwa ikozvino) inoshandura shanduko kuti ishandiswe pamwe chete ne1.5A-6A yakakura-mutoro watt-awa mita, kuitira kuti dzivisa dambudziko rekuchinja reshiyo kazhinji..
Bhokisi rezviridzwa rakabatana neyechipiri mhepo yekubuda kweiyo yakasanganiswa transformer.Bhokisi rezviridzwa rakashongedzerwa neatatu-phase inoshanda watt-awa mita uye reactive watt-awa mita imwe neimwe, kana matatu-chikamu inoshanda uye inogadzirisa yakasanganiswa simba mita, iyo inogona kunyatsoonekwa kubva mucherechedzo bhokisi rewindo.Verenga nhamba dzacho.
(1) JLSZV-35 akatevedzana akasanganiswa mashanduri anounganidzwa kubva pakaoma imwe chete zvikamu, uye hapana dambudziko rekudonha kwemafuta, saka mafuta-isina anowanikwa;
(2) Magetsi neazvino zvese zvinokandwa neresin, senge chivakwa chekuvaka, chiri nyore kutsiva, chiri nyore kuchengetedza, uye chinochengetedza mutengo;
(3) Chigadzirwa chine yakanyanya kurongeka, uye ikozvino transformer inogona kusvika 0.2S level, iyo inoona yakakura kuyerwa kwemutoro;
(4) Kushandiswa kwezvinhu kunoita kuti chigadzirwa chive nepamusoro pesimba uye kugadzikana kwekupisa;
(5) Chikamu chemagetsi chinogona kuve chakashongedzerwa ne220V yekubatsira mhepo kuti ipe simba rekuchinja, nezvimwe.
Mamiriro Ekushandisa:
1. Tembiricha iri pakati -45°C ne40°C, isingadarike avhareji yemazuva ose tembiricha ye35°C;
2. Kukwirira hakupfuuri 1000 metres (ndapota ipai urefu kana uchishandisa munzvimbo dzakakwirira);
3. Mhepo inomhanya: ≤34m / s;
4. Hunyoro hunyoro: chiyero chezuva nezuva hachipfuuri 95%, uye mwedzi wepamwedzi hausi kupfuura 90%;
5. Shock resistance: horizontal acceleration 0.25g, vertical acceleration 0.125g;
6. Ichi chigadzirwa chinogona kushanda kwenguva yakareba pa 1.2 nguva iyo inonzi voltage factor;
7. Device chikwata: panze composite insulation yakazara yakavharwa chimiro;
8. Uremu hwechigadzirwa: 485Kg (kusanganisira kusunga uremu);
9. Surface creepage kureba: 1300mm;
10. Rated insulation level: 40.5/95/200 kv

Kuiswa uye wiring

1. Iyo yakakwirira-voltage metering bhokisi inofanira kuiswa yakatwasuka, kureba kwekuisa padanda hakufaniri kunge kwakaderera kupfuura 300mm kubva pasi, uye watt-awa mita inofanira kuva yakatwasuka uye isingarereki pakuda.
2. Mhedzisiro yemagetsi ekupedzisira (yekutanga inopinda mutsara wedivi) ye-high-voltage metering box inofanira kuiswa ne zinc oxide arrester yezinga rinoenderana nevoltage, uye kumira kwayo kwepasi kuduku kudarika kana kuenzana ne10Ω kudzivirira kuputika kwemheni kwakasiyana-siyana, kushanda overvoltages, uye simba frequency transient overvoltages, kuitira kudzivirira Magetsi midziyo uye magetsi midziyo mutsetse.
3. Kune wiring, kutevedzana kwechikamu A, B, C yemagetsi emagetsi emagetsi anofanirwa kuonekwa ne-high-voltage electric energy metering box, uye kutevedzana kwechikamu A, B, uye C yerodhi inofambisa inofanira kubatanidzwa maererano ( kutevedzana kwechikamu kunofanirwa kuve kwakanaka), P1 mutsara unouya, P2 unobuda mutsetse.
4. Double ratio yekubatanidza nzira: shandura yechipiri wiring: batanidza S1-S2 yediki reshiyo reshiyo (S3 pfupi), batanidza S1-S3 kune yakakura renji reshiyo (S2 pfupi).
5. Kana chiyero chiri chimwe chete, yechipiri S2 yezvino transformer uye yechipiri b yevoltage transformer yakabatanidzwa pasi.Kana iyo yechipiri ikozvino transformer ichichinja chiyero cheviri nechiyero chidiki, iyo S2 uye voltage transformer b yakabatana pasi (S3 haina chinhu) , kana uchishandisa yakakura shanduko reshiyo, S3 yakabatana nekudzika kweiyo voltage transformer b. (S2 ipfupi).
6. Kana iyo high-voltage line iine aluminium, inofanira kunge yakanyatsobatanidzwa nemhangura-aluminium transition clips, chassis yose inofanira kunge yakadzika pasi, transformer iripo haifaniri kuvhurwa kechipiri, uye transformer yemagetsi haifaniri kuva pfupi. -kutenderera kechipiri.
7. Mushure mokunge bhokisi re-high-voltage metering rakagadzikwa, edza uye cherechedza nemutoro kuti uone kana iyo inoshandiswa uye inogadzirisa simba mita inotenderera kazhinji.
8. Mushure mekuedzwa kwakazara uye kuongororwa, inogona kuiswa zviri pamutemo mukushanda mushure mekupasa bvunzo.
