40.5kV 72.5kV 145 kV 252kV Series Dead Tank circuit breaker

Uchanganithi wa bidhaa：

LW58A-40.5/72.5/145/252 Dead Tank circuit breaker ni mbinu mpya ya kifaa cha umeme chenye kiwango kikuu kilicho undwa bila msaidizi, Circuit breaker hii ya tank inajumuisha entrance bushing, lead-out bushing, CT, arc extinguishing chamber, chassis, operating mechanism, na kadhalika. Inaweza kutumika maeneo yasiyofaa kama vile eneo la baridi sana na ulimwengu mkali, Sasa, mbinu mpya ya LW58A-40.5/72.5 zimefikia kiwango cha kimataifa cha juu katika teknolojia na uhakika ya ubora.

Masharti muhimu：

•  Uwezo mzuri wa kupambana na zemio, bidhaa hii ni sawa na daraja la GIS za zemio.

  （a）Mkakati wa arc extinguishing chamber wa upande, center of gravity chache.

  （b）Seismic frequency ya kujitengeneza: Circuit breaker ya porcelain column ni karibu 4.5 Hz, na tank circuit breaker ni karibu 13.5 Hz.

• Hatua ya electric tracing band inaweza kutumika maeneo yanayopanda baridi, ambayo haipatikani katika circuit breaker ya porcelain column.

• Bidhaa hii inaweza kutumika katika eneo la 5000m, arc extinguishing chamber & drive system standard configuration inaweza tu kupelekwa kwa ukungu wa outlet casing.

•  Circuit breakers ya tank zinajumuisha current transformer wa straight through, bidhaa hii inajaza nchi ndogo, ubora unaendelea, na kazi ya huduma ya eneo ni ndogo. Pia, inatatua masuala kama vile margin ndogo wa insulation ya CT, uwekezaji wa CT unaweza kukosa, gharama kubwa, aging, cracking, na explosion ya CT.

•  Design ya arc extinguishing chamber：Mfumo wa upande, huo unatumia teknolojia ya thermal expansion na gas extinguishing auxiliary pressure, ambayo ina kazi ndogo, ufanyiko mzuri, na electrical life zaidi ya 20.

• Uwezo wa kusikiliza mazingira:Inaweza kutumika kwenye mazingira magumu (kama vile mazingira ya mazingira, mizigo, hall, na kadhalika), eneo la ukungu mkali, seismo, box body imefungwa na air bag type, na protection grade ya IP66.

• CT ya variable ratio na multi-level combination inaweza kuongezwa, uwezo mzuri, rahisi kukuongeza uwekezaji, na kufanikiwa 80% au operating frequency voltage chini ya thamani ya 5Pc, inaweza kuunganishwa na TPY.

•  Masharti kamili ya CT protection: CT shell imefungwa pamoja na viwanja vya mwisho na design maalum ya ant-condensation.

• Operating mechanism ya light spring inatumia cast aluminum frame kamili. Breaking spring, closing spring, na buffer zimeanzishwa kwa njia moja, na zote zinatumia spiral double pressure spring, mfumo wa kijiji, si rahisi kupungua.

• Bidhaa hii ni ndogo, na integrated design, integrated supply, na integrated installation conditions.

• Na uwezo wa kupinda 4000A back-to-back capacitor bank.

Masharti muhimu ya teknolojia:

Order Notice:

• Model na format ya circuit breaker.

• Rated electrical parameters (voltage, current, break current, na kadhalika).

• Masharti ya kazi (temperature, ukungu, na mazingira ya mazingira).

• Operating voltage ya operating mechanism na motor voltage.

• Idadi ya current transformer, current ratio, class combination, na secondary load.

• Names na idadi ya spare items needed, parts, na special equipment and tools(to be otherwise ordered).

Ni nini masharti ya structure ya tank circuit breaker？

Integral Tank Structure：

• Integral Tank Structure: Arc quenching chamber, insulating medium, na components related zimefungwa ndani ya metal tank yenye insulating gas (kama vile sulfur hexafluoride) au insulating oil. Hii inafanya space safi na ifunguliwa, inapunguza mazingira ya nje kutokufanya athari kwenye components za ndani. Mfano huu unaimara uwezo wa insulation na uhakika wa kifaa, kunawezesha kutumika kwenye mazingira mbaya za nje.

Arc Quenching Chamber Layout：

• Arc Quenching Chamber Layout: Arc quenching chamber mara nyingi inastahimili ndani ya tank. Mfumo wake unatumika kufanya arc quenching kwenye nchi ndogo. Kulingana na principles na teknolojia tofauti za arc quenching, construction specific ya arc quenching chamber inaweza kuwa tofauti, lakini kwa kawaida inajumuisha components kama vile contacts, nozzles, na insulating materials. Components hizi zinajitunza kwa kutosha ili arc ikiwa breaker inaruhusu current.

Operating Mechanism：

• Operating Mechanism: Operating mechanisms zinazotumika zinajumuisha spring-operated mechanisms na hydraulic-operated mechanisms.

• Spring-Operated Mechanism: Aina hii ya mechanism ina mfumo wa kawaida, inapatikana na rahisi kudhibiti. Inadhibiti operations za opening na closing za breaker kwa kutumia energy storage na release ya springs.

• Hydraulic-Operated Mechanism: Aina hii ya mechanism inatoa faida kama vile output power kubwa na smooth operation, inaweza kutumika kwenye high-voltage na high-current class breakers.
