Amaphutha ajwayelekile ama-circuit breaker avuzayo

Faka ohambweni

1) Ulayini wamandla wezigaba ezintathu, okuhlanganisa nolayini ongathathi hlangothi, awudluli ku-zero sequence current transformer ohlangothini olufanayo, vele ulungise izintambo.

I-2) Kukhona uxhumano lukagesi phakathi kwesekethe ene-breaker circuit yokuvuza efakiwe kanye nesifunda ngaphandle kwe-breaker circuit yokuvuza efakiwe, futhi izifunda ezimbili zingahlukaniswa.

I-3) Kukhona imithwalo yomlilo owodwa kanye nomhlabathi owodwa emgqeni, futhi kwanele ukuqeda imithwalo enjalo.

4) Ulayini ongathathi hlangothi osebenzayo odlula ku-zero ukulandelana kwamanje kwe-transformer inesisekelo esiphindaphindiwe, futhi ukugxilisa okuphindaphindiwe kufanele kuqedwe.

I-5) I-breaker circuit yokuvuza ngokwayo inephutha futhi kufanele ishintshwe.

Ukungasebenzi kahle

1. Ibangelwa ukugcwala ngokweqile.Ngokwesibonelo, iI-circuit breakeringenziwa isebenze uma i-overvoltage yokusebenza yenzeka kulayini.Ngalesi sikhathi, ukulibaziseka noma i-impulse voltage non-acting leakage circuit breaker ingakhethwa, noma i-resistance-capacitance absorption circuit ingafakwa phakathi koxhumana nabo ukuze kucindezelwe i-overvoltage.Idivayisi emunca i-overvoltage ifakwa kulayini.

2. Ukuphazanyiswa kwe-electromagnetic.Uma kukhona okokusebenza kazibuthe noma okokusebenza kukagesi okunamandla amakhulu eduze, indawo yokufaka isihlukanisi sesekethe esivuzayo kufanele ilungiswe ukuze iqhelelane nezinto ezinjalo zikagesi.

3. Ithonya lokujikeleza.Uma ama-transformer amabili esebenza ngokufana, anesisekelo sawo.Ngenxa yokuthi ama-impedances ama-transformer amabili awakwazi ukulingana ngokuphelele, lokhu kuzokhiqiza amandla ajikelezayo ocingweni oluphansi futhi kubangele ukuthi i-breaker circuit isebenze.Vele ususe intambo eyodwa yaphansi.Ukwengeza, i-transformer efanayo inikeza amandla kumthwalo ofanayo ngokusebenzisa izifunda ezimbili ezihambisanayo, futhi ama-currents kuma-circuits amabili angeke afane ncamashi, futhi kungase kube khona ukujikeleza.Ngakho-ke, izifunda ezimbili kufanele zisetshenziswe ngokuhlukana.

4. Ukumelana nokufakwa kwe-insulation kocingo olusebenzayo olungathathi hlangothi kuncishisiwe.Lapho ukuncishiswa kokumelana kwentambo engathathi hlangothi esebenzayo kuncishisiwe, uma umthwalo wezigaba ezintathu ungalinganiseli, kuzovela igagasi elisebenza ngokulinganayo kucingo olungathathi hlangothi futhi ligeleze kwamanye amagatsha emhlabathini, ukuze ukuvuza kwamanje kubonakale ekuvuzeni ngakunye. i-circuit breaker , Yenza i-circuit breaker ingasebenzi kahle.

5. Isisekelo esingafanele.Uma intambo emaphakathi imiswa phansi ngokuphindaphindiwe, izobangela ukungasebenzi kahle kwe-breaker circuit.

6. Ithonya lokugcwala ngokweqile noma isifunda esifushane.Uma i-circuit breaker evuzayo inokuvikela kwesekhethi emfishane kanye nokuvikela okudlulele ngesikhathi esifanayo, ukungasebenzi kahle kuzokwenzeka uma ukulungiselelwa kwamanje kweyunithi yohambo lokuvikela lwamanje kungafanele.Ngalesi sikhathi, lungisa inani lamanje lesilungiselelo.
