Iyo yakaderera-voltage kugovera mutsara inoreva mutsara unoderedza yakakwirira-voltage 10KV kusvika 380 / 220v nhanho kuburikidza nekugovera transformer, ndiko kuti, iyo yakaderera-voltage mutsara inotumirwa kubva kune substation kuenda kumidziyo.

Iyo yakaderera-voltage yekuparadzira mutsara inofanirwa kutariswa pakugadzira iyo wiring nzira ye substation.Kune mamwe maworkshops ane simba guru rekushandisa, iyo workshop ine zvakare ine transformer substation.Iyo transformer inopa simba kumagetsi emagetsi, nepo For workshops ine simba shoma rekushandisa, magetsi anopiwa zvakananga nemushanduri wekugovera.

Low-voltage simba rekugovera nzira

Iyo yakaderera-voltage kugovera mutsara inogadzirwa uye yakaiswa kunze maererano nerudzi, ukuru, kugovera uye chimiro chemutoro.Kazhinji, kune nzira mbiri dzekugovera, radial uye trunk mhando, sezvinoratidzwa mumufananidzo uri kurudyi.

Mitsetse yeRadial ine kuvimbika kwakanaka, asi mari yekudyara yakakwira, saka ikozvino yakaderera-voltage simba rekugovera wiring inowanzoshandiswa hunde mhando, iyo inogona kuwana yakakwana kuchinjika.Kana iyo tekinoroji yekugadzira ichichinja, mutsara wekugovera haudi kuita shanduko huru.Mutengo wemagetsi wakaderera, iyo ndiyo miviri yayo mikuru.Zvechokwadi, maererano nekuvimbika kwemagetsi emagetsi, hazvina kunaka semhando yeradial.

Mhando dzemitsetse yakaderera-voltage yekugovera

Kune nzira mbiri dzekuisa dzeyakaderera-voltage yekuparadzira mitsara, iyo, nzira yekuisa tambo uye pamusoro pemutsetse wekuisa nzira.

Nekuda kwekuti tambo yetambo yakaiswa pasi pevhu, ine zvishoma zvechisikigo zvinokanganisa kunze kwenyika, senge mhepo ine simba uye icing, uye hapana waya dzinoburitswa pasi, nekudaro kushongedza chitarisiko cheguta uye nharaunda yechivako, asi mari yekudyara. yetambo yetambo yakakwirira, uye kugadzirisa kwakanyanya kuoma., zvakanakira mitsetse yepamusoro zvakangopesana.Naizvozvo, kune nzvimbo dzisina zvakakosha zvinodiwa, iyo yakaderera-voltage wiring inotora iyo yepamusoro mutsara nzira.

Mitsetse yakaderera-voltage pamusoro pepamusoro inowanzogadzirwa nematanda kana mapango esimende kugadzira mapango erunhare, uye mabhodhoro eporcelain anoshandiswa kugadzirisa waya pamhanza dzemapango.Nhambwe iri pakati pematanda maviri ingangoita 30 ~ 40M muchivanze, uye inogona kusvika 40 ~ 50M munzvimbo yakashama.Nharaunda pakati pewaya ndeye 40 ~ 60 cm.Iyo erection yemutsara ipfupi sezvinobvira.Zviri nyore kuchengetedza uye kugadzirisa.

Bhokisi rekugovera panzvimbo yekuvaka

Mabhokisi ekugovera panzvimbo dzekuvaka anogona kukamurwa kuita mabhokisi ekugovera akajairwa, mabhokisi akagadzika ekugovera uye mabhokisi ekugovera mafoni.

Kana iri yakazvimirira transformer, iyo transformer uye huru yekugovera bhokisi mushure mekunge yaiswa neiyo magetsi ekupa bureau.Iyo huru yekugovera bhokisi ine yakazara yakaderera-voltage yedunhu breaker, inoshanda uye inoshanda watt-awa mita, voltmeters, ammeters, voltage transfer switch, uye chiratidzo chemwenje.Wiring yemutsara webazi rimwe nerimwe renzvimbo yekuvaka inofanira kubatanidzwa nebhokisi rekugovera bazi seri kwebhokisi guru rekugovera.Kana iri pole-mounted transformer, mabhokisi maviri ekugovera akaiswa padanda, uye ndege yepasi yebhokisi inopfuura 1.3m kubva pasi.DZ yakatevedzana yakaderera-voltage circuit breakers inoshandiswa mubhokisi rekugovera.Iyo yese yedunhu breaker inosarudzwa zvinoenderana neyakayerwa ikozvino ye transformer.Mutsara wega wega webazi unodzorwa nedunhu redunhu rine diki diki.Kukwanisa kwemutsigiri wedunhu kunosarudzwa maererano nehuwandu hwehuwandu hwemazuva ano hwedunhu.Kana iyo yazvino iri diki, inofanirwa kunge iri Sarudza leakage switch (yakanyanya kuwanda kweiyo leakage switch ndeye 200A).Huwandu hwema sub-circuit breaker hunofanirwa kuve humwechete kana maviri kupfuura huwandu hwemapazi akagadzirwa sematavi ekuchengetedza.Bhokisi rekugovera nzvimbo yekuvaka harina kugadzirirwa ikozvino uye voltmeters yekutarisa.

Kana isiri shanduko yakazvimirira, asi shanduko yepakutanga inoshandiswa, bhokisi guru rekugovera uye bhokisi rekugovera shunt rinosanganiswa, uye iyo inoshanda uye inogadzirisa watt-awa mamita inowedzerwa.Kutanga kubva kubhokisi guru rekugovera, mutsara wekumashure unotora TN-S nhatu-chikamu cheshanu-waya system, uye simbi shell yebhokisi rekugovera inoda kubatanidzwa kune zero kudzivirira.

Yakagadziriswa bhokisi rekugovera:

Nekuda kweiyo yakawanda-chinangwa tambo mutsara wakaiswa panzvimbo yekuvaka, iyo magetsi emagetsi system anotora iyo radial mhando, uye imwe neimwe yakagadziriswa bhokisi rekugovera ndiyo yekupedzisira yebazi iri, saka inowanzoiswa padyo nemagetsi ebazi iri.

Iyo goko reiyo yakagadziriswa yekugovera bhokisi remagetsi rakagadzirwa nesimbi yakaonda ndiro, uye kumusoro kunofanira kunge kusina mvura.Kureba kwemuviri webhokisi kubva pasi kwakakura kupfuura 0.6m, uye kona yesimbi inoshandiswa sekutsigira gumbo.Chete 200 ~ 250A main switch, ichishandisa ina-pole leakage switch, iyo simba ndiyo yakanyanya kuyerwa ikozvino yemidziyo yemagetsi mubhokisi, tichifunga nezvekuita kwakasiyana-siyana, inogona kugadzirwa zvichienderana nemamiriro ekutanga emidziyo yakasiyana-siyana inoshandiswa munzvimbo yekuvaka. , sekufunga kuti bhokisi rimwe nerimwe rinogona kubatanidzwa kune shongwe crane kana Welder.Dzakati wandei shunt switch dzakaiswa kuseri kweiyo main switch, uye mana-pole leakage switch anoshandiswa zvakare, uye huwandu hunosanganiswa zvichienderana neyakajairwa midziyo yemagetsi.Semuenzaniso, main switch inoshandisa 200A leakage switch, ine matavi mana, maviri 60A uye maviri 40A.Chiteshi chepasi cheshunt switch chinofanirwa kuve chakashongedzerwa neporcelain plug-in fuse sechinhu chiri pachena chekudimburira uye chinoshandiswa sechigadziriso chekuisa waya.Chiteshi chepamusoro chefuse chakabatana nechiteshi chezasi cheiyo leakage switch, uye chiteshi chepasi hachina chinhu chemidziyo wiring.Kana zvichidikanwa, imwe-phase switch inofanira kuiswa mubhokisi, yakagadzirira kushandiswa ne-single-phase equipment.

Semagumo emutsara webazi, kuitira kusimbisa kuvimbika kwekuchengetedzwa kweiyo neutral line grounding.Kudzokorora kugadzika kunofanira kuitwa pane imwe neimwe yakagadziriswa bhokisi rekugovera.

Mushure mekunge waya yaunzwa mubhokisi, tambo yezero inoshanda yakabatana neiyo terminal bhodhi, mutsara wechikamu wakabatana zvakananga kune chepamusoro chiteshi cheiyo leakage switch, uye inodzivirira yakarerekera mutsara inodzvanywa pane yepasi bhaudhi paganda re bhokisi rekugovera uye rakagadzika kakawanda.Mushure mebhokisi rekugovera Idziviriro zero mutsara wakabatanidzwa kune iyi bolt.
