Izifutho Zokumisa I-Vacuum Interrupter

Ngokusebenzisa amapharamitha okwakheka kwe-waveform elungiselelwe esigabeni sokuklama, onjiniyela bavumela ama-bellows ukuthi afinyelele ukushaya okuphezulu ngaphakathi kwezikhala ezivalekile ngenkathi begcina ukusebenza okuthembekile kokuvala. Lo mklamo omusha usungula isithiyo sokuvala esinamandla ngaphakathi kwegumbi lokuphazamisa i-vacuum, okugcina ngempumelelo indawo ye-vacuum ephezulu kakhulu ezingeni lika-10^-8 Pa ukuze kube lula ukucima i-arc ngokushesha.

Ngesikhathi sokusebenza kwangempela, izimbobo kumele zibhekane nezimo eziningi ezimbi kakhulu ngasikhathi sinye: ukumunca ukushaqeka komshini okuvela ezindleleni zokusebenza kwe-breaker, ukukhokhela ukwanda/ukufinyela kokushisa okubangelwa ukushintshashintsha kwezinga lokushisa lokushintshashintsha kwamanje, kanye nokumelana nokudlidliza kukagesi okubangelwa yi-arcing. Ukuze kuhlangatshezwane nalezi zinselele, kwenziwa izinqubo ezikhethekile zokufaka kanye nokwelashwa kwendawo ngesikhathi sokukhiqiza, okuthuthukisa kakhulu amandla okubamba kanye nokumelana nokugqwala kwezinto.

Ukuze kuqinisekiswe ikhwalithi, i-bellow ngayinye idlula ezivivinyweni ezingaphezu kwamashumi amabili eziqinile okuhlanganisa ukutholwa kokuvuza kwe-helium mass spectrometry kanye nokuhlolwa kokuphila kokukhathala, okuqinisekisa ukuthi amazinga okuvuza ahlala engaphansi kwesilinganiso samazwe ngamazwe esingu-1×10^-10 Pa·m³/s.

Nakuba kusetshenziswa ngokwesiko kuma-circuit breaker angu-12kV-40.5kV aphakathi nendawo, izixazululo ezenziwe ngokwezifiso ziyatholakala zemishini ye-EHV ngokusebenzisa imiklamo ye-convolution enezingqimba eziningi noma izinto ezikhethekile. Ngokuthuthukiswa kwegridi ehlakaniphile, ama-bellows anamuhla manje ahlanganisa ukuzwa kokufuduka ukuze aqaphe ukuguguleka kokuxhumana ngesikhathi sangempela, okwenza kube lula ukulungisa okubikezelayo.

Ngokusebenzisa ukwenziwa ngcono kwezinto zokwakha kanye nokuthuthukiswa kokumboza okuvikelayo, imikhiqizo yesizukulwane esilandelayo igcina ukusebenza okuzinzile emazingeni okushisa aphezulu (-40°C kuya ku-+150°C) ngenkathi imelana nokugqwala kokufuthwa kukasawoti ogwini noma ukuguguleka kwamakhemikhali ezimboni.

Le ngxenye esebenza kahle kakhulu - ehlanganisa isayensi yezinto zokwakha, ubunjiniyela bemishini kanye nobuchwepheshe be-vacuum - iyaqhubeka nokushayela i-switchgear kagesi ekuthembekeni okukhulu, ukuqina kanye nobuhlakani, isebenza njengesici esiyisisekelo sengqalasizinda yegridi ehlakaniphile.
