Mafiyan da kalmomin hanyar tsaro na shunt reactor tare da circuit breakers a cikin IEE-Business

Muhimmin Da Iya Maimaita Daga Farkon Kirkiyar Aiki na Tashar Kirkiya

A cikin kirkiyoyi masu amfani da tsari (CB), an yi hanyoyi daban-daban don taimaka wa wani abu da ke faruwa a matsayin kawo gaba ta kirkiya (TRV) da sauran abubuwan farkon kirkiya. Hadi sun hada da wasu hanyoyi masu ma'ana tare da albashi da mafi yawa:

1. Rizistorin Kirkiya

• Albashi: Yana ba da damar ziyara zuwa inganci a lokacin da kirkiya ta kirkira, wanda ya taimaka wa iya kawo gaba daga farkon kirkiya.

• Mafi yawa:

• Tasirin Inganci: Rizistorin kirkiya yana kasance tasirin inganci ga kirkiya, musamman ga kirkiyoyi masu SF6 mai tsari, wanda ba ya fi shiga a kan al'amura ko kudin rai.

• Babu Iya Kammala Wace Zama: Nawaishe ne, akwai karin zama a kan rizistorin kirkiya.

2. Surge Arrester to Ground at Shunt Reactor

• Albashi: Yana da muhimmiyar a kan kirkiyoyi masu amfani da tsari wanda suke samun farkon kirkiya mai kyau da ya fi girma a kan surge arrester.

• Mafi yawa: An yi amfani da shi kawai a kan wasu irin kirkiyoyi, kuma tushen da aka samu shi ana iya zama mai mahimmanci; babu iya amfani da shi a kan duk fagen fagen.

3. Surge Arrester Across the Circuit Breaker

• Albashi: Yana ba da muhimmin daidai na iya maimaita daga farkon kirkiya a lokacin da kirkiya ta kirkira.

• Mafi yawa:

• Tasirin Inganci: Idan an yanke surge arrester, yana kasance tasirin inganci ga kirkiya.

• Kudin Kammalawa: Surge arrester ya kamata a iya kammala kudin da suka faruwa a kan ido na kirkiya.

• Babu Iya Kammala Wace Zama: Akwai karin zama a kan kirkiyoyi masu tsari mai kudin kadan, musamman a kan kirkiyoyi masu tsari mai kudin kadan.

4. Surge Capacitor

• Albashi: Yana iya kawo gaba daga farkon kirkiya a wasu fagen fagen.

• Mafi yawa:

• Babu Iya Amfani Da Shi a Kan Kirkiyoyi Mai Tsari Masu Kyau: Surge capacitors bai ba da muhimmiyar a kan kirkiyoyi masu tsari masu kyau ba, musamman a kan irin vacuum.

• Yana Kasance Kirkiyar Chopping: Zan iya kasance kirkiyar chopping, amma bai ba da muhimmiyar a kan kirkiyar suppression peak overvoltages ba.

• Babu Iya Kammala Wace Zama: Babu iya kammala wace zama, kuma zan iya kammala zamanin minimum arcing kafin ya fi kammala kudin da suka faruwa.

• Buƙatar Yanayi: Yana buƙata yanayi don yanke.

5. Controlled Switching

• Albashi: Yana da muhimmiyar a kan kirkiyoyi masu tsari mai inganci da kalmomin minimum arcing time, tare da tushen da aka samu shi a kan ido na kirkiya.

• Mafi yawa:

• Ingantaccen Amfani: An yi amfani da shi kawai a kan kirkiyoyi masu tsari mai inganci, kuma wasu amfani suka buƙata ido na pole mai inganci, wanda ya kasance tasirin inganci.

6. Circuit Breaker with Higher Voltage Rating

• Albashi: Idan an zama tsarin kirkiya, yana iya kawo gaba daga farkon kirkiya.

• Mafi yawa:

• Kudin Raya: Kirkiyoyi masu tsari mai kyau suna da kudin raya.

• Buƙatar Yanayi: Yana buƙata yanayi don yanke.

Gajarta

Har canza hanyoyi na iya maimaita daga farkon kirkiya na da albashi da mafi yawa. Zan iya zaɓe hanyoyi a kan hukumar da take, irin kirkiya, da kuma buƙatar ido. Misali, idan an yi amfani da rizistorin kirkiya, zan iya ba da damar ziyara, amma bai ba da shiga a kan duk irin kirkiya ba saboda tasirin inganci. Duk da haka, surge arresters da surge capacitors suna ba da muhimmiyar, amma suna da tasirin inganci da buƙatar yanayi. Controlled switching yana da muhimmiyar a kan wasu fagen fagen, musamman a kan kirkiyoyi masu tsari mai inganci, kuma kirkiyoyi masu tsari mai kyau suna ba da muhimmiyar a kan iya maimaita daga farkon kirkiya, amma suna da kudin raya da buƙatar yanayi.
