Sistemin Da Gaskiya Ingantaccen Tashin Karamin Faduwa Gas Protection Overcurrent da Kudin Aikace-aikace na IEE-Business

Don samun fitaccen cutar da takaice, kafin da takawa da dukkuka, da kuma abubuwa na gida, zai yi amfani da wasu alamomin inganci, kuma za su shiga cikakken bayanai:

• Zai yi amfani da muhimmin alamomin ingancin darasi masu iye mai yawa da 10 MVA ko kadan, da kuma muhimmin alamomin ingancin darasi masu iye mai yawa da 6.3 MVA ko kadan da suka fi girma. Zai iya yi amfani da muhimmin alamomin ingancin darasi masu iye mai yawa da 6.3 MVA ko kadan da suka fi girma saboda hanyar muhimmanci.

• Zai iya yi amfani da alamomin ingancin darasi masu iye mai yawa da 10 MVA ko kadan da suka fi girma da alamomin ingancin darasi. Idan iye mai yawa ta alamomin ingancin darasi ya fi girma da 2 MVA ko kadan, amma ba sa shiga hukumomi, ana sanya a yi amfani da muhimmin alamomin ingancin darasi.

• Idan iye mai yawa ta alamomin ingancin darasi ya fi girma da 0.4 MVA ko kadan, kuma tsari mai yawa ta 10 kV ko kadan, da kuma takawa mai tsabta da kafin kasa, zai iya yi amfani da alamomin ingancin darasi na biyu da relay uku.

• Dukkan alamomin inganci da aka bayar sarrafa suna yi amfani a matsayin babban alamomin ingancin darasi don in tara jirgin kafin da ake gano.

A lokacin da ake amfani da alamomin ingancin darasi, akwai wani lokaci da zai iya zama rasu a gano abubuwan da ake fito a cikin darasin, kuma zai iya zama rasu a taimaka. Yana iya a yi amfani da gas relay protection don in taimaka wajen kare matakin da ke faruwa.

Bayani game da Gas Protection

Gas protection ita ce babban alamomin ingancin darasi, kuma yana ciki a nan alamomin ingancin da ba suka da kayan aiki. Ana kawo shi a nan light gas protection da heavy gas protection. Tsarin aiki suna da wahala: Light gas protection ta yi aiki idan abubuwan da ake fito a cikin darasi suna haifar da kayan aiki, kuma suna haifar da gas. Gas ya ji karkashin relay, kuma open cup ta gama bukatar tsaro da ta zo ne, ta haifar da reed contact zuwa kula da alarami. Heavy gas protection ta yi aiki idan abubuwan da ake fito a cikin darasi suna haifar da kayan aiki ko kungiyoyi, kuma suna haifar da gas da kungiyoyi mai karfi zuwa oil reservoir. Kungiyoyin ya ji baffe na relay, kuma ya gama magnet zuwa kula da reed contact, ta haifar da trip command. Yana da kyau a kan trip mode. A nan alamomin ingancin da ake amfani a nan masu darasi mai kayan aiki, akwai pressure relief da kuma sudden pressure change protection.

Yadda ake faɗa daga light gas protection da heavy gas protection ita ce cewa light gas protection tana kula da alarami ba tana haifar da trip, amma heavy gas protection tana haifar da trip kawai.

Zero-sequence voltage ita ce sum of vectors of three-phase voltages. Hanyar aiki na zero-sequence current yana da nasara.

Tsarin aiki na heavy gas protection tana da float da kuma reed relay design. Oil chamber na relay tana haɗa da transformer tank. Idan gas ya faru, gas ya ji karkashin float zuwa wurin, ta haifar da first-stage contact zuwa kula da light gas alarm. Idan gas ya faru, float ta zo ne, ta haifar da second-stage contact, ta haifar da heavy gas circuit, ta haifar da trip circuit breaker.

Yadda ake faɗa daga Tsarin aiki na Light da Heavy Gas Protection

Light gas relays tana da open cup da kuma reed contacts, kuma tana yi aiki don in kula da alarami. Heavy gas relays tana da baffle, spring, da kuma reed contacts, kuma tana yi aiki don in haifar da trip.

A lokacin da ake amfani da relay, an haɗe shi da oil, kuma open cup tana tsoro saboda tsaro. Idan abubuwan da ake fito a cikin darasi suka faru, gas tana ji karkashin oil, ta haifar da open cup zuwa kula da alarami.
