High voltage circuit breakerinoreva dunhu rinogona kubatanidzwa, kubviswa uye kushandurwa kuita zvigadzirwa zvemagetsi.Zvinoenderana nekuti kune ikozvino mudunhu, iyo HV yedunhu breaker yakakamurwa kuita on-load switch uye hapana-mutoro switch.Iyo ine yakakwira arc kupera kwekuita uye inogona kudzima kana kudzima pamusoro-voltage uye pamusoro-ikozvino kuchengetedzwa musimba remagetsi mukati menguva yakatarwa.Kune magridi ane huwandu hwe500 kV kana kupfuura, kushanda nguva nenguva kunodiwa zvakare kuve nechokwadi chekuchinjika kwakakwana uye kugadzikana kwehurongwa.
Maitiro ekuita
1 、 Iyo yedunhu inotyora ine mabasa ekudzivirira kwepamusoro-voltage uye kuchengetedzwa kwepfupi-redunhu, uye inogona kushandiswa kudzivirira uye kutonga kwemitsara, kugovera zvishandiso uye mitoro.
2, Iyo inotyora wedunhu ine basa rekudzima arc, uye inogona kukurumidza uye nekuvimbika kugura arc mukati megumi ms.
3, Iyo yedunhu inotyora ine hunhu hwekuvhura kupfupi uye kuvhara nguva, uye inokodzera nzvimbo dzekugara uchishanda.
4, Iyo yedunhu inotyora inogona kuona hapana-mutoro kupatsanura basa, iyo inofambisa kazhinji kushanda uye kupfupisa nguva yemagetsi kuchekwa.
5、 Iyo inonyanya kuchengetedza-isina muhupenyu hwese kutenderera;panguva yekudzima, iyo nguva yekusavenda kwekufamba uye static kushamwaridzana uye pasina magetsi emagetsi pakuvhara coil yedunhu breaker ipfupi, iyo inova nechokwadi chekuti cheki chinotyora chisatsva.
6, Iyo ine hunhu hwevhoriyamu diki uye huremu huremu.
7, Vacuum arc yekudzima kamuri ichagamuchirwa uye arc yekudzima dhizaini yekudzora ichashandiswa pachinzvimbo chemanyorero ekushandisa;arc yekudzima kamuri ichave yakavimbika, compact mukugadzira uye diki muhukuru hwekuisa.
Nheyo yekushanda
Kana iyo yedunhu inopwanya simba, iyo inofamba inobata mumagetsi inotyaira chitubu chekuvhara kuburikidza nemuchina wekutapurirana kuvhara wedunhu.Chitubu chechirimo chinoita kuti mupfuri avhare panzvimbo.
Kana iyo yedunhu yatsemuka, iyo inofamba uye yakamira madhiri inoparadzaniswa, uye iyo inofamba inobatika mumeshini inogadziriswazve kutanga, uye ipapo dunhu rinogurwa nekutyaira kupatsanura nekuvhara kubatanidza tsvimbo pasi pechiito chesimba rechirimo.Iyo chinzvimbo cheiyo inofamba yekubata uye iyo static yekubata inodzorwa neyechitubu simba rekuchengetedza meshini kuchengetedza iyo yekusangana mune imwe nzvimbo.
Mukuwedzera, kune zvimwe zvinhu zvakadai selatching switch, nezvimwewo, izvo zvinoita kuti muparadzi wedunhu achengetedze imwe nzvimbo panguva yekupwanya nekuvhara, kuitira kudzivirira kukanganisa uye kukanganisa.
Chimiro chechimiro
1. Mutambo wedunhu unoumbwa negomba, boka rekubatana, kamuri yekudzima arc, arc inodzima kusangana, kushamwaridzana kwekubatsira uye nzira yekushanda.Nekuti iyo yekubata uye inovhiringidza kamuri yedunhu rebreaker yakapatsanurwa uye yakasanganiswa nemagetsi emagetsi, chimiro chekubata chine simba guru pakuita kwedunhu rinotyora.
2. Circuit breakers ichakamurwa kuita air insulated circuit breakers uye vacuum arc interrupters zvichienderana nearc yakasiyana inovhiringa midhiya, uye inokamurwa kuva load switch type uye vacuum arc interrupter type zvichienderana nemamiriro akasiyana ekushandisa.
3. Kuti ugone kugonesa kupatsanurwa kwakavimbika uye kusanganisa pakati peboka rekuonana neboka rekuonana, chinzvimbo chekumisa nzira inorongwa muboka rekusangana.Nzvimbo yekushandura inodzorwa nemuganhu wemubato.Akasiyana mabreaker ane akasiyana magumo maitiro, asi ese ane anowirirana mabasa.
Classification
1, Zvinoenderana nemaitiro ekushanda kweanopwanya edunhu, kune marudzi maviri emabreaker: pa-load-breaker uye no-load breaker.
2, Madhiri edunhu anogona kuiswa muoiri redunhu rinotyora, vacuum redunhu rinotyora uye sarufa hexafluoride redunhu rinotyora zvinoenderana nepakati pekudzima arc.
3, Maererano nemusimboti wekudzima arc, kune marudzi maviri ekudzima arc, imwe ndeye arc inodzima isina arc, imwe yacho arc inodzima pasina arc.Nekuti hapana arc circuit breaker mukuvhara maitiro, nekuda kwesimba remagetsi, hazvibviri kuwana kupera kwakazara.
Yekutanga inoshandisa mweya seanodzivirira svikiro uye iyo yekupedzisira inoshandisa sulfur hexafluoride seanodzivirira svikiro.
5, Zvinoenderana nechikamu chekuchengetedza mabasa, inogona kukamurwa kuita pfupi dunhu chengetedzo yekukanganisa uye isiri-pfupi yedunhu chengetedzo yekukanganisa.
