40.5kV 72.5kV 145kV 170kV 245kV Dead tank Vacuum Circuit-Breaker

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.

Kiwataccen Tank Mai Tsari:

• Kiwataccen tank mai tsari: Ƙasashen kawo hanyar zuwa, mutanen gine-gine da sauransu suna fi sako a kan tankin kaya da gas (kamar sulfur hexafluoride) ko zama. Wannan yana taimaka wajen haɓaka fadin gine-gine da kyau, kuma yana iya taimaka wajen inganta shirin da amanna cikin abincin. Wannan kayan aiki na iya amfani a wurare dabara daban-daban.

Tsarin Ƙasashen Kawo Hanyar:

• Tsarin ƙasashen kawo hanyar: Ƙasashen kawo hanyar yana fitowa a cikin tanki. Tsarinsa yana kunshi muhimman abubuwa kamar mafi girma, nozzles, da mutanen gine-gine. Abubuwan da suka yi aiki waɗanda suke taimaka wajen kawo hanyar da shirye-shiryen lokaci.

Mekanisumin Yawanci:

• Mekanisumin yawanci: Mekanisumi masu amfani a cikin wannan al'adun ya kunshi mekanisumin spring da hydraulic.

• Mekanisumin spring: Wannan mekanisuminsa yana da tsari mai yawa, yana da amanna, da kuma yana da shirin da ba ta da shakka. Yana amfani da energy na spring don taimaka wajen kawo da kwarin lokacin.

• Mekanisumin hydraulic: Wannan mekanisuminsa yana da shirin da kyau, yana da shirin da ba ta da shakka, kuma yana da amfani a wurare da shirye-shiryen lokaci da kuma damar lokaci.

1. Tattalin kwalba na gas mai yawan kwalba
Gas-gas da ke CO ₂ da perfluoroketone/nitrile: kamar gas-gas da ke CO ₂/C ₅ - PFK (perfluoroketone) ko CO ₂/C ₄ - PFN (perfluoronitrile). Wasu gas-gas da suka kungiyar da suka gudanar da kyau a kwalba da CO ₂ da kuma kyauwar tattalin kwalba na perfluorinated ketones/nitriles, wanda ya ba su shi da iya zama batun da take canza SF ₆ a fannin kwalba mai tsawon lami. Misali, gas da ke CO ₂/C ₄ - PFN ta fi sani da amfani a cikin circuit breakers masu kwalba mai tsawon lami, da kwalbar da kuma kyauwar tattalin kwalba na baka da SF ₆, da kuma ci gaban darajar da ke tsayi a kan global warming potential (GWP).
Gas da ke air da perfluoroketone: A fannin kwalba na masu tsaye, gas da ke air da C ₅ - PFK zai iya amfani a cikin tattalin kwalba. Ta haka, tare da inganci da pressure, zai iya samun kwalbar da kula da SF ₆, amma da kuma ci gaban darajinsa a kan yawan kwalba.
2. Fanni na vacuum circuit breaker
Chamber na vacuum arc extinguishing: Da amfani da kyauwar tattalin kwalba da kuma kyauwar kwalba a matsayin vacuum, ita ya zama batun da take canza funktar kwalba na SF ₆. Vacuum circuit breakers suna amfani da su a fannin kwalba na masu tsaye da kusa, musamman a wurare da ke da muhimmanci ga yawan kwalba. Abubuwan da suke da su sun hada da babu gas da ke tsayi a kan yawan kwalba da kuma kyauwar kwalba, amma ya kamata a kammala masu shafi kamar vacuum sealing da kuma abubuwa masu contact materials.
Kungiyar da vacuum circuit breaker da gas insulation: A wasu switchgear masu kwalba na tsaye, ana amfani da vacuum circuit breakers a matsayin elements masu kwalba, kungiyar da dry air ko nitrogen da ke gas insulation, don samun environmentally friendly gas insulated switchgear (GIS) wanda ya koyar da kwalbar da kuma kyauwar kwalba.
