Kamfanin Gidaje-turbin na 120kA da Kyautar Kirkiro Tsakiya

Bayanan:

Wannan abincin shiga shi ne na gaba-gaban daɗi masu hanyar kammalawa cikin kusurwa mai yawa. A shekarar 2019, an yi takamantar da ita a kan Ma'aikatar Yakin Bimari na Nijeriya, kuma tana da fadada mai yawa a kan mulkin daɗi da na duniya. Yanzu, an bayar da 28 abinci zuwa manyan birnin Wudongde da Baihetan. 

Fadada Abinci:

• Fadada mai tsawo mai yawa: tana da kyau a tsawon kasa da 30,000A da lokacin da 50 minutsi.

• Fadada mai karfi mai yawa: tana iya ci gaba da tsarin daɗi da earthing switch 10,000 kafa.

• Kyau a tsawon kasa: brake switch ta taka muhimmiyar nasara a tsaron kasa da load current, da kasa 28,000A.

• Fadada mai amana: akwai zuba a tsakiyar brake switch. Idan tasiri ya lala da 1.2 MPa saboda matsalolin daɗi, za a fitar da gas don haifar da suka shafi waɗanda suke da abubuwan da suke. Tsarin abinci tana ba da kyau a gudanar da tashar daɗi.

Tsarin Abinci:

• Abinci tana da uku single poles, kuma kowane pole tana da metal enclosure mai karfi waje da take daɗi a cikin chassis babban.

• Brake switch tana da hydraulic spring operating mechanism; earthing switch tana da motor operating mechanism; kowane mode tana da linkage mechanical tri-phase.

• Tsari mai yawa tana da cooling mai yauje.

• Kowane operating mechanism tana daɗi a cikin abinci da ke kontrola.

• SF6 tana amfani da ita a kan insulation da arc-extinguishing medium brake switch, kuma contact arc-striking tana da copper-tungsten material mai karfi, wanda tana bincika fadada da tsarin brake switch.

• Earthing switch tana da air a kan insulation medium, fixed contact tana daɗi a cikin support main circuit, moving side tana daɗi a cikin bottom plate box body, kuma moving contact tana daɗi a cikin single phase enclosure da take daɗi earthing circuit through closed bus bar connected with the moving contact.

• Tsari mai yawa brake switch tana da kyau a tsarin daɗi da ke fitar da installation da maintenance a cikin yanayi.

Daga baya, wani standard na lokacin da generator circuit breaker ta daɗi?

Lokacin daɗi da closing times generator circuit breakers ba da standard mai yawa. Standards na musamman suna daidaita da type da voltage level, application scenario, da kuma standards da regulations. Kadan shine bayanai game da standards:

Closing Time (Making Time)：

• Standard Range: Gaskiya, lokacin daɗi generator circuit breakers tana da tsari mai yawa daga few tens of milliseconds to over one hundred milliseconds. Misali, common medium-voltage generator circuit breakers tana da lokacin daɗi daga 30ms to 80ms, while high-voltage, high-capacity generator circuit breakers tana da lokacin daɗi mai yawa, amma tana da limits within 100ms.

• Relevant Standards: Daga standards, three-phase asynchronism closing time for generator circuit breakers ba zai iya ƙare 5ms.

Opening Time (Breaking Time)：

• Standard Range: Lokacin daɗi tana da sum of the closing time and the arc burning time. Value tana daidaita da factors. Gaskiya, for medium-voltage generator circuit breakers, lokacin daɗi tana da tsari mai yawa daga 50ms to 150ms, while for high-voltage, high-capacity generator circuit breakers, lokacin daɗi tana da tsari mai yawa daga 100ms to 250ms.

• Relevant Standards: For different voltage levels and types of generator circuit breakers, transient recovery voltage during interruption of short-circuit currents, load currents, and out-of-step currents tana da requirements. First-pole factor and magnitude factor tana da 1.5.
