Tambayar Da Duk da Amfani da Automatic Circuit Recloser a Kulaɗi na Ƙarshen Kulaɗin Kirkiro

An Automatic Circuit Recloser shi ne karamin kwallon kashi mai inganci da take da kawo (yana da muhimmanci na fuskantar kashi, yadda ake yi nasarar kashi, da kuma yadda ake yi nasarar kashi, bili da yaɗuwar kawo ko kamar kawo). Yana iya tafi da kashi da jirgin kashi a cikin hanyar, tafi da kashi masu nasarar da kuma yi nasarar kashi a matsayin yadda ake yi nasarar kashi, da kuma yi nasarar kashi a matsayin lokacin da aka sani.

1. Muhimmanci da Nau'o'i na Feeder Automation da Take da Automatic Circuit Recloser Scheme

Yin kawo da karamin kashi na samun kashi da take da Automatic Circuit Recloser scheme ta yi amfani da kyakkyawan karamin kashi da kuma ayyukan kawo, kuma yin kawo, da kuma kawo. Bili da yaɗuwar kawo ko kamar kawo, wannan hanyar ta yi nasarar kashi da kuma kawo a matsayin yadda ake yi nasarar kashi da kuma lokacin da aka sani, wanda ke taimaka waɗannan kawo zuwa kashi.

Muhimmancin mafi yawa da Automatic Circuit Recloser scheme ta yi shine kawo. Yana iya kawo bili da yanayin kawo, wanda ke taimaka waɗannan kawo zuwa kashi. Idan an samu yanayi, za a iya kara kawo da kawo don in samu kawo da kawo.

Kawo da karamin kashi da take da Automatic Circuit Recloser yana daidai da shugaban kashi, kamar halayansu "hand-in-hand" looped networks. A cikin wannan haɗin, biyu kashi suna da zama da karamin kashi. A lokacin da yaɗuwar kashi, karamin kashi ya fi yawa, kuma kashi ya fi yawa. Idan an samu nasarar kashi a kashi, za a iya kawo kashi don in ba da kashi da kawo, wanda ke taimaka waɗannan kawo zuwa kashi.

A cikin rukunin Figure 1, B1 da B2 su ne karamin kashi daga substations; R0 zuwa R2 su ne karamin kashi (Automatic Circuit Reclosers). A lokacin da yaɗuwar kashi, B1, B2, R1, da R2 suka fi yawa, R0 ya fi yawa.

• Nasarar kashi a Section ①: Don nasarar kashi na gajeru, za a iya kawo kashi a matsayin lokacin da aka sani ɗaya ko biyu. Don nasarar kashi na tsakanin, idan B1 ya yi nasarar kashi kuma ya yi nasarar kashi, R1 ya samu nasarar kashi a Section ①. Ba lokacin da aka sani, R1 ya fi yawa. Sannan, R0 ya samu nasarar kashi a Section ② lokacin da aka sani t₂ (t₂ > t₁) kuma ya yi nasarar kashi, wanda ke kawo nasarar kashi a Section ①.

• Nasarar kashi a Section ②: Nasarar kashi na gajeru za a iya kawo kashi a matsayin lokacin da aka sani ɗaya. Don nasarar kashi na tsakanin, idan R1 ya yi nasarar kashi kuma ya yi nasarar kashi, R0 ya samu nasarar kashi a Section ② lokacin da aka sani t₂ kuma ya yi nasarar kashi. Idan ya yi nasarar kashi, ya yi nasarar kashi, wanda ke kawo nasarar kashi a Section ②. Wannan hanyar ta yi nasarar kashi a duk sections da ke kan karamin kashi.

Abubuwa masu amfani a cikin hanyar:

• Don in kawo nasarar kashi da take da Automatic Circuit Recloser scheme, ya kamata a kawo kawo da yaɗuwar kashi da kawo da kawo, kuma a kawo kawo da lokacin da aka sani.

• Idan an samu nasarar kashi a kashi, za a iya kawo kashi da karamin kashi. Karamin kashi suka iya kawo kashi lokacin da aka sani, kuma lokacin da aka sani suka fi yawa da karamin kashi.

Sistem na kawo da karamin kashi da take da kawo da kawo, za a iya kawo kashi da kawo da kawo. Duk da haka, saboda Automatic Circuit Reclosers na zamani su ne microprocessor-based da intelligent, suke bayar da interfaces don kawo da kawo. Idan an samu yanayin kawo, za a iya kara kawo da kawo zuwa kawo da kawo.

2. Yadda a Kawo Da Inganci Na Kashi Da Kuma Tsara Lokacin Da Kashi Ya Yi Nasarar Kashi

• Amfani da PLC (Programmable Logic Controller) da takamfiyar a matsayin kontrol na Automatic Circuit Recloser.

• Kawo nasarar kashi na gajeru lokacin da aka sani. A cikin kashi, 70% na nasarar kashi su ne gajeru. Idan a yi nasarar kashi na gajeru kamar nasarar kashi na tsakanin, za a iya kasance lokacin da aka sani. Saboda haka, an kara kawo kashi a matsayin lokacin da aka sani a Automatic Circuit Reclosers, wanda ke kawo nasarar kashi na gajeru lokacin da aka sani, wanda ke tsara lokacin da aka sani.

• Kawo nasarar kashi a biyu da ke kan nasarar kashi. Karamin kashi na zamani su iya kawo nasarar kashi a karamin kashi. Amma, Automatic Circuit Reclosers su iya kawo nasarar kashi a biyu da ke kan nasarar kashi, wanda ke kawo nasarar kashi a duk sections da ba suka nasarar kashi, tsara lokacin da aka sani, kawo nasarar kashi, kuma kawo nasarar kashi.

3. Abubuwa Masu Amfani Da Automatic Circuit Reclosers a Cikin Kashi

• Kurfa da Yawanci: Duka abubuwa masu gaba da za suka faru zai iya samun hukuma a matsayin abubuwa masu gaba mai yawa, don haka ya ba tushen da yawa ba ne cewa an yi shiga. Kiyasin da ya faru zai iya samun hukuma kawai idan abubuwan da suka faru sun fi tsawo.

• Zaɓe da sauran Automatic Circuit Reclosers na gaskiya da kyau a cikin rukuni da take da zama da tsari ga jerar da ita.

• Zaɓe rated current, breaking capacity, short-circuit current rating, da dynamic/thermal withstand current ta Automatic Circuit Recloser a cikin wurin da ake zaba. Rated current na short-circuit masu yawan da yake daɗe ya kamata yana cikin 16 kA don inganta zama ga grid.

• Sauran settings na protection na gaskiya, musamman trip current, number of reclosing attempts, da time-delay characteristics.

• Bayyana waɗannan Automatic Circuit Reclosers na faduwa da karamin faduwa: number of allowed fault current operations yana iya rage level by level, sannan time delay for reclosing yana iya ciyar level by level (a yanzu ana bayyana 8 seconds per stage).
