Umehluko phakathi kwebhokisi legatsha lekhebula kanye neyunithi eyinhloko yendandatho

Umsebenzi oyinhloko webhokisi legatsha lekhebula ukuhlukanisa noma ukushintshanisa izintambo. Ukuqhekeka kwekhebula. Ukuthwala izintambo eziningi ezincane endaweni yonke emzileni onebanga elide kuvame ukuholela ekuphazanyisweni nasekuchithekeni kokusetshenziswa kwekhebula, ngakho-ke lapho kungaphandle kwemingcele yomthwalo wamandla, isigxobo esiyinhloko kanye nezintambo ezinkulu zivame ukusetshenziswa ngaphandle kwemingcele. Ikhabethe lokhuni lokusabalalisa noma ukudlulisa ikhebula, elihlukaniswe phakathi kuka-X no-X, lokusabalalisa umthwalo noma ukudlulisa ikhebula elide.
Iyunithi eyinhloko yeringi: ibhokisi lokusabalalisa ikhebula elineswishi lingasetshenziswa kude. Isiteshi sokushintsha: isiteshi sokusabalalisa esincane nesiphakathi esingenamuntu esinomgwaqo webhasi owodwa noma uxhumano lwebhasi elilodwa ngesigaba

Amabhokisi egatsha lekhebula ngokuvamile asetshenziswa ngaphandle. Ngokuthuthuka kobuchwepheshe, amabhokisi egatsha lekhebula anezinkinobho nawo athuthukiswa njalo, futhi izintambo emadolobheni amakhulu zivame ukusebenzisa indlela yokuphakelwa kwamandla e-dual-circuit, ngakho abantu abaningi bazibiza ngokushesha ngokuthi ibhokisi legatsha elinenkinobho. Liyiyunithi eyinhloko yendandatho yangaphandle, kodwa iningi leyunithi eyinhloko yendandatho kulesi sigaba alikwazi ukugcina ukwenziwa ngokuzenzakalela kokusabalalisa.

1. Izingxenye zeyunithi eyinhloko yendandatho:
Iyunithi eyinhloko yendandatho eyaziwa nangokuthi ibhizinisi lesistimu yokuphakelwa kwamandla enethiwekhi yendandatho, iyiqembu lemishini nemishini ye-high-voltage circuit breaker efakwe emzimbeni wekhabethe lensimbi elijiyile noma imishini kagesi eyenziwe kwimoduli yesistimu yokuphakelwa kwamandla enethiwekhi yesikhala se-assembly ring, eminye yayo isebenzisa ukushintsha komthwalo nama-fuse aphezulu. Iyunithi ngayinye eyinhloko yendandatho inikezwa indlela yokuxhuma eguquguqukayo yamabhokisi aphansi angu-3 kuya kwangu-5, ukuze kucatshangelwe izidingo zesistimu yokuphakelwa kwamandla zama-node ahlukene enethiwekhi yokusatshalaliswa kwamandla. Ngenxa yokuthi imishini yokushintsha kwamandla eyinhloko kanye ne-busbar eqinile kufakwe ekhasethini elifanayo lensimbi elivaliwe, ngokuvamile kusetshenziswa njengezingqimba zokufaka umswakama kanye nezinto zokucisha i-arc. Izicubu eziphuzi ezi-snap zingagcina iswishi isebenza ngokushesha. Imoduli yenethiwekhi yendandatho ezimele yakhiwe ngamamoduli okulawula ahlukene namamoduli e-busway njengezinkampani zezintambo ezinhlanu zesigaba sesithathu, amayunithi enani, amabhizinisi e-TV, njll., futhi angakha izinhlelo ezahlukene ezahlukene ngokuthanda ngokwezidingo zangempela.

2. ukuhlukaniswa kweyunithi eyinhloko yendandatho:

Iyunithi eyinhloko yendandatho ingahlukaniswa ngezinhlobo ezine:

a. Iyunithi eyinhloko yendandatho yohlobo lwephampu yomshini wokuhlanza: Iyunithi eyinhloko yendandatho yohlobo lwephampu yomshini wokuhlanza iyisizukulwane esisha somkhiqizo weyunithi eyinhloko yendandatho yomshini wokuhlanza oluhlaza okwesibhakabhaka. Lo mkhiqizo usebenzisa i-vacuum circuit breaker + idivayisi yokuvikela i-microcomputer, futhi wonke amasekethe aqhubayo asebenzisa i-epoxy resin glue noma i-silica gel. I-encapsulation iqinisekisa ukuphepha okuphezulu ekusebenzeni nasekusebenzeni kwangempela, futhi i-voltage elinganisiwe yesicelo ingafinyelela ku-24KV.
b. Iyunithi eyinhloko yendandatho ye-SF6: Iyunithi eyinhloko yendandatho ye-SF6 uhlobo lwezinto zasekhaya ezine-voltage ephezulu enesendlalelo sokuvimbela igesi noma isendlalelo sokuvimbela umusi esine-load switch njengengxenye eyinhloko, engakhiwa kalula ukufinyelela kwe-multi-circuit, ukuguqulwa, uxhumano kanye nokugcinwa kohlelo lokunikezwa kwamandla. Imishini yokwenza. Izingxenye zayo eziyinhloko zesekethe zakhiwa i-SF6 load switch noma i-isolation switch eyengeziwe kanye namanye amathuluzi asizayo nezinto zasekhaya.
c. Iyunithi eyinhloko yendandatho ekhiqiza igesi: Iyunithi eyinhloko yendandatho ekhiqiza igesi yenziwe ngezinto zokusetshenziswa eziqinile ezikhiqiza igesi (njengezingqwembe ze-plexiglass) ukwenza izingxenye zokucisha i-arc. Izinto zokusetshenziswa ezikhiqiza igesi ziguqulwa zibe yigesi, epholisa amanzi kagesi bese iwakhipha. Uma inani lamandla kagesi ahlukanisiwe nahlanganisiwe likhulu, ukuhlukaniswa kukagesi kuqina, igesi eguquliwe iba nkulu, futhi umphumela wangempela wokucisha i-arc uba mkhulu.
d. Iyunithi eyinhloko yendandatho yomoya ecindezelwe: Iyunithi eyinhloko yendandatho yomoya ecindezelwe iqanjwe ngokukhethwa kweswishi yomthwalo womoya ocindezelwe. Iswishi yomoya ecindezelwe isebenzisa ukucindezela komoya ukushaya i-arc. Uma idonswa, induku yomoya ecindezelwe inyakaza ngokushesha, futhi igesi enomfutho ophezulu esilinda ishaywa iye ekuhlukanisweni kukagesi nge-nozzle lapho i-arc extinguishing circuit breaker ihlukaniswa ukuze kubangele ukuhlukaniswa kukagesi. Yenza i-electric solitary ibe yinde bese uyishaya lapho ugesi uphansi. Ngokuvamile, ugesi weswishi yomthwalo womoya ocindezelwe cishe u-1 kA, ukuze kufezwe amandla okuphuka kanye nowe-short-circuit angu-50 kA. Ugesi ozinzile wokushisa ngokuvamile u-20 kA, 3s.

3. Yiziphi izici zesakhiwo sekhabhinethi yenethiwekhi yendandatho?
a. Ikhabhinethi yenethiwekhi yendandatho yakhiwe izingxenye ezine: igumbi lokushintsha, igumbi le-fuse elinogesi ophezulu, igumbi lokuhlela okusebenzayo kanye negumbi lekhebula (isipilingi sepuleti).
b. Igumbi lokushintsha lakhiwe yisekethe ngayinye esebenzayo (kufaka phakathi iswishi yedivayisi yokumisa kanye neswishi yomthwalo) evalwe esikhaleni sezinto zensimbi kanye nebha yebhasi phakathi kwamasekethe. Isembozo sishintshwa ngokushintshwa ngogesi kwepuleti eligoqekile elibandayo elingu-3mm (noma ipuleti lensimbi elijiyile elingenayo imifekethiso). Isekethe ngayinye yesenzo iqukethe iswishi yomthwalo kanye neswishi yokumisa. Iswishi yomthwalo yakhiwe yisofthiwe yesistimu yokumisa isekethe yokuhamba yokuqina komzimba kanye nokuxhumana okungaguquki okutholakala ekugcineni kwewebhu engezansi. Lapho iswishi ivalwa kabusha, i-circuit breaker ehambayo iyehla bese iswishi yomthwalo ixhunyiwe. Iswishi yedivayisi yokumisa yakhiwe ngommese wokuthintana oshukumayo kanye nommese wokuthintana ongaguquki. Phakathi nenqubo yonke yokuzivocavoca kokuqina komzimba okuphuzi okugxumayo, iswishi yedivayisi yokumisa ixhunywe ngokushesha. Kunezimbobo ezine zenqubo yokugaya phezulu nangemuva kwegumbi lokushintsha, kanti uhlangothi olungemuva lweyunithi eyinhloko yendandatho lufakwe ifasitela lokubuka, futhi izingxenye "zokuhlukanisa" kanye "nokuvala" zeswishi yedivayisi yokumisa umhlaba zingabonakala. Uhlangothi olungemuva lweyunithi eyinhloko yendandatho lufakwe imishini engaqhumi.
c. Iswishi yokulayisha isebenzisa isakhiwo somoya ocindezelwe, esinekhono eliqinile lokucisha i-arc futhi asilimazi imibala emibili kanye nesendlalelo sokuvikela phansi. Kokubili oxhumana nabo abaguquguqukayo nabanganyakazi baqukethe ama-arc circuit breaker, okuthuthukisa kakhulu imvamisa yokuphuka.
d. I-fuse ene-voltage ephezulu kanye negumbi lokushintsha umthwalo kwakha isekethe yokulungisa i-transformer. I-fuse ene-voltage ephezulu ifakwe ekhava yokuvikela i-epoxy resin-cast. Ngemva kokuba i-fuse ene-voltage ephezulu ivuthelwe, i-striker iyaphuma bese i-load switch ivalwa.
e. Igumbi lokuhlela ukusebenza litholakala ohlangothini oluphambene lweyunithi eyinhloko yendandatho. Kuso sonke isifunda sesenzo, inkinobho yokulayisha ifakwe inhlangano yokusebenza kwentwasahlobo yokugcina amandla yabasebenzi (noma kagesi), kanti inkinobho yedivayisi yokugcina amandla ifakwe intwasahlobo yokugcina amandla yabasebenzi. Inhlangano yokusebenza ephuzi, iphaneli yokulawula inezikhala zokusebenza kwangempela kokuvala inkinobho yokulayisha kanye nenkinobho yokudonsa ngesandla kanye nenkinobho yedivayisi yokufaka phansi, kanye nemigodi yokusebenza kwangempela yokuvala, ukuvula inkinobho yokulayisha kanye nokuvala izibani zokubonisa isikhundla kanye nohlobo lukagesi Vula futhi uvale kabusha izinkinobho, bese usetha umugqa wokulingisa wokulingisa, isikrini sokubonisa isimo sokushintsha kanye nengxenye yokukhiya, ukusebenza kwangempela kwenkinobho yokulayisha kanye nenkinobho yedivayisi yokufaka phansi ifakwe imishini yokukhiya ukuze kugwenywe amaphutha okusebenza
