RHB type Live tank SF6 gas circuit breaker

1. Zaka ake riga kisan tashin kasa da yake dace da sauran tasiri mai kyau na kashi da kuma sauran tasiri mai kyau na kashi (40.5/72.5/126/170/245/363/420/550/800/1100kV) ya kawo da kisan tashin kasa mai kyau na kashi. Misali, don ƙasar kashi na 35kV, ana zama ake riga kisan tashin kasa na 40.5kV. Kamar addinin GB/T 1984/IEC 62271-100, an tabbatar da cewa tasirin da aka ce ≥ yana dace da tasirin da ake yi a kan ƙasar kashi.
2. Ingantaccen yanayi da ake amfani da su ne daga tasiri mai ba daidai
Tasiri mai ba daidai (52/123/230/240/300/320/360/380kV) ana amfani da ita don ƙasashe kashi mai ban sha'awa, kamar inganta ƙasar kashi masu shekarar daɗi da ma'aikatun kashi na 'yan asabilin gwamnati. Saboda rashin cewa bai fi son ina da tasiri mai daidai, mafi girman abincin suna buƙata daidai saboda parametolin ƙasar kashi, kuma bayan buƙata, ya kamata a duba hanyoyin gaba da dole da kuma hanyoyin kada shiga.
3. Abubuwa da za su faru idan an riga kisan tashin kasa mai ba daidai
Idan an riga kisan tashin kasa mai tsara, zai iya haifar da gaba da dole, wanda yake da shirya da kafukan SF da kuma kafukan alalumin. Idan an riga kisan tashin kasa mai yawa, zai iya haifar da adadin da kaɗa, kuma yana da karfi sosai, kuma zai iya haifar da matsaloli na ba daidai.

1. Yadda na musamman suna da muhimmanci shine zabe-zabin da ake amfani da su don kawo lalacewa: Kuli-kulisu da ke amfani da tsafta (10⁻⁴~10⁻⁶Pa) don hirnata da kawo lalacewa; Kuli-kulisu da ke amfani da gasin SF₆, wanda yake da kyau a ƙare elektronon don kawo lalacewa.
2. A fayyace da jiki: Kuli-kulisu da ke amfani da tsafta suna daidai da jiki masu sauransu (10kV, 35kV; wasu zuwa 110kV), ba da 220kV+. Kuli-kulisu da ke amfani da gasin SF₆ suna daidai da jiki masu yawan da gaba (110kV~1000kV), suna fi sani a jerin jiki masu yawan da gaba.
3. Don kwayoyin: Kuli-kulisu da ke amfani da tsafta suna kawo lalacewa da kadan (<10ms), suna da tsarin kawo lalacewa ta 63kA~125kA, suna daidai da amfani na kadan (misali, kudin kashi) da tsari mai tsauri (>10,000 waɗannan). Kuli-kulisu da ke amfani da gasin SF₆ suna fi shahara a kawo lalacewar kashi mai yawa/induktif, amma suna yi abubuwan da kadan, suna bukata lokacin da zabe-zabin ya haɗa don kawo lalacewa.

1. Dukkan farko da ke tsari a tashar circuit breakers na porcelain column da tank—biyu na tsohon ƙasashe na high-voltage circuit breakers—sun fi yin zuwa shida abubuwa mafi muhimmanci.
2. A cikin tsari, kowace masu porcelain column suke ake taimaka da pillars na porcelain insulation, tare da components da suka fitowa da arc extinguishing chambers da operating mechanisms. Tank types sun amfani da metal-sealed tanks don bincike da highly integrate duka abubuwan da suka fiye.
3. Don insulation, kowace masu porcelain column suke amincewa da pillars na porcelain, air, ko composite insulating materials; kuma tank types sun amfani da gas-gasai na SF₆ (ko wasu insulating gases) tare da metal tanks.
4. Arc extinguishing chambers suna fitowa a tsohu ko pillars na porcelain columns don kowace, amma ana gina a cikin metal tanks don tank types.
5. A cikin application, kowace masu porcelain column suke zama dabam a matsayin outdoor high-voltage distribution tare da layout da ya fiye; tank types sun iya adana a matsayin indoor/outdoor scenarios, musamman a cikin environments da suke da space-constrained.
6. Maintenance-wise, exposed components na kowace suke amincewa don targeted repairs; sealed structure na tank types sun haɗa da overall maintenance frequency amma sun bukatar full inspections don local faults.
7. Technically, kowace masu porcelain column suke bayar da intuitive structure da strong anti-pollution flashover performance, amma tank types sun neman excellent sealing, high SF₆ insulation strength, da superior resistance to external interference.
