Bayanan da Fadada Hybrid Circuit Breaker

Hybrid circuit breakers (CBs) suna kara gajarta mai yawa a fannin tsakiyar yanayi na takalma masu sauri, wanda ya kare mafi girman vacuum da SF6 (a nan CO2) interrupters. An yi abin da shi a cikin zabe ta hybrid don samun fadada mafi girma daga wani interrupter zuwa wani, don haka ya ba shi nasarorin mafi yawa da fadada al'umma. A nan ne bayanin fadada muhimman:

1. Samun Fadada Tsakacewar Yana Yi

• Abubuwan Samun Fadada Tsakacewar Yana Yi: Zabe ta hybrid CB yana iya ba shi abubuwan samun fadada tsakacewar yana yi daga vacuum da CO2 arcs, wanda yana dogara hanyoyin tsakacewar yana yi da kyau:

• A Cikin Rike: Arc ta CO2 yana taimakawa arc ta vacuum a farkon rike na tsakacewar yana yi, wanda yana taimaka waɗanda ake tsakace ta da kyau.

• Ba Cikin Rike: Arc ta vacuum yana taimakawa arc ta CO2 a lokacin tsarkake, wanda yana ba shi inganci masu kyau ga transient recovery voltage (TRV). Wannan yana ba shi tsakacewar yana yi masu amana da damu, musamman idan TRV ta fito da kyau.

• Mafi Girma Tsakacewar Yana Yi: Yanayin vacuum da CO2 interrupters yana iya ba hybrid CB shi hanyoyin tsakacewar yana yi masu mafi girma (misali, 63 kA) bila buƙata masu kyau ko yanayin alama masu juye. Wannan yana ba shi zabe masu ci gaba da inganci.

2. Fadada Al'umma

• Fiye Da Gasar SF6: Daga cikin fadadan muhimman na hybrid CBs shine fiye da gasar SF6 da CO2. SF6 shine gasar da ya fi karfi ga al'umma masu kyau da gasar CO2. Ta haka, ta amfani da CO2 a matsayin medium ta tsakacewar yana yi, hybrid CBs suna ci gaba fadada al'umma da ke faruwa a kan gasar SF6.

• Babu Fadada Al'umma: CO2 shine gasar da ba a dukkanta ba, ba a tattalin sanka ba, kuma ana iya samun shi, wanda yana ba shi alternative masu amana da kyau da gasar SF6. Wannan yana haɗa da yanayin disposal da maintenance, kuma yana ci gaba fadada al'umma na wurin.

3. Samun Inganci a Farkon Sai

• Inganci a Farkon Sai: Hybrid CBs suka duba da zabe masu amfani a farkon sai. Mafita da SF6-based CBs, wanda suka iya samun fadada inganci ko fuskantar ayyuka a farkon sai, hybrid CBs suna ci gaba hanyoyin tsakacewar yana yi masu mafi girma hatta a lokutan sauran sau. Wannan yana ba shi hanyoyin amfani a cikin manyan lokutan, musamman lokutan da ke da harmattan mai yawa.

4. Zabe Masu Ci Gaba Da Kiyaye

• Tsarin Vacuum Mai Yawa: Abubuwan gajarta da suka faru a cikin fannin vacuum interrupter technology suka iya ba shi hanyoyin kiyaye da inganci. Ana samun vacuum bottles masu kiyaye da inganci wanda za su iya haɓaka short-circuit currents masu mafi girma. Wannan kiyaye yana ba shi zabe masu ci gaba da kiyaye na hybrid CB, wanda zai zama zai iya amfani da shi da kyau da kuma taimaka kan power systems da ke da su.

• Babu Buƙatar Masu Kyau: Zabe ta hybrid ta fiye da buƙatar masu kyau don taimakawa interruption, wanda yana ci gaba kiyaye da alamar zabe ta. Wannan yana ba shi hanyoyin amfani masu kyau da kuma babban cost-effectiveness.

5. Amana Da Taurari

• Inganci Masu Kyau: Yanayin vacuum da CO2 interrupters yana ba shi hanyoyin amfani masu amana da kyau a cikin fannin tsakiyar yanayi na takalma masu sauri. Hanyoyin vacuum interrupter da ya iya haɓaka TRVs masu fito, tare da hanyoyin CO2 interrupter da ya iya haɓaka tsakacewar yana yi, yana ba shi inganci da taurari a lokacin lokaci.

• Kadan Inganci Masu Kyau: Saboda zabe ta amana da amfani da abubuwan mutanen al'umma, hybrid CBs suna buƙatar kadan inganci masu kyau da traditional SF6-based CBs. Wannan yana ci gaba downtime da cost of operation.

Kammala

Hybrid circuit breakers suna ba shi hanyoyin amfani masu kyau a cikin fannin tsakiyar yanayi na takalma masu sauri, wanda suka kare mafi girman vacuum da CO2 interrupters. Su na samun fadada tsakacewar yana yi, fadada al'umma, samun inganci a farkon sai, da kuma zabe masu ci gaba. Wannan fadada suka ba shi hanyoyin amfani masu kyau a cikin power systems na zamani, musamman a lokutan da fadada al'umma da amana suka fi muhimmanci.
