Me kana Yadda ake Bincike Bayan Annabi Amfani da Hima (Buchholz) na Tausayi?

Ga wasu Tushen da ake Yi Ba Taushe Gas (Buchholz) Protection Ya Faru?

Idan taurari gas (Buchholz) protection ya faru, yana bukata a yi noma mai karfi, bincike mai karfi, da kuma fahimta mai karfi, sannan a yi ayyuka daidai.

1. Idan Shanin Gas Protection Ya Faru

Idan shanin gas protection ta faru, ya kamata a yi noma na taurari bi ba gaba don tabbatar da abin da suka faru. Bincika idan an faru saboda:

• Gas mai hawa,

• Tsakiyar mai hawa kadan,

• Galmi a cikin rawa na biyu, ko

• Galmi na taurari a cikin taurari.

Idan gas an samu a cikin relay, ya kamata a yi ayyukan:

• Raketa tsamfuta gas;

• Bincika launin da kuma ruwa gas;

• Bayyana idan gas zai iya kawo karshe;

• Samu sampali gas da kuma mai hawa don bayyana gas mai hawa (DGA) ta hanyar gas chromatography.

Gas chromatography yana nufin bayyana gas da aka samu ta hanyar chromatograph don tabbatar da daidai da kuma raketa ma'adaddinsu kamar hydrogen (H₂), oxygen (O₂), carbon monoxide (CO), carbon dioxide (CO₂), methane (CH₄), ethane (C₂H₆), ethylene (C₂H₄), da acetylene (C₂H₂). Ta hanyar abubuwan da kuma ma'adaddinsu, ana iya tabbatar da natijin, tsarin, da kuma kadan galmi a cikin taurari masu inganci da kuma mutanen bayanai (e.g., IEC 60599, IEEE C57.104).

• Idan gas a cikin relay ya fi launi, ya fi ruwa, kuma bai iya kawo karshe, da kuma bayyana gas chromatography ta tabbatar da ce gas mai hawa, taurari zai iya ci gaba. Amma, yanayin gas mai hawa (e.g., lafiya mai hawa, kalmomin gas mai hawa) ya kamata a tabbatar da kuma a kore a wani lokaci.

• Idan gas zai iya kawo karshe da kuma bayyana gas mai hawa (DGA) ta sampali mai hawa ta tabbatar da abin da ke kusa, ya kamata a yi binciken daidai don tabbatar da idan taurari zai iya ci gaba ko kuma karkashin gida.

2. Idan Relay Gas Yana Taushe (Karkashin Gida)

Idan Buchholz relay ya taushe da karkashin gida, taurari ba za a ci gaba har zuwa maimakon tabbatar da abin da suka faru da kuma kore galmi daga taurari.

Don tabbatar da abin, ya kamata a yi binciken daidai da kuma bayyana waɗannan abubuwa haɗa:

• An faru saboda lafiya mai hawa ko kalmomin gas mai hawa a cikin conservator tank?

• Aikin protection da kuma rawa na biyu na DC suna faɗa?

• Ana samu abubuwan da ake duba a kan taurari wanda ke nuna natijin galmi (e.g., kafuwarsa mai hawa, taurari mai kyau, alama mai kawo karshe)?

• Gas a cikin relay gas zai iya kawo karshe?

• Me koyarwa a kan bayyana gas chromatography ta relay gas da kuma gas mai hawa?

• An samu abubuwan da ake duba a kan ayyukan daidai (e.g., insulation resistance, turns ratio, winding resistance)?

• An faru ayyukan daidai na transformer relay protection (e.g., differential protection, overcurrent protection)?

Kammala

Tushen daidai a kan faruwa na Buchholz relay yana da muhimmanci don tabbatar da taurari da kuma inganci na gwamnatin kasa. Noma mai karfi, bayyana gas, da kuma binciken daidai galmi yana da muhimmanci don tabbatar da abubuwan da ke kusa (e.g., gas mai hawa) da galmi mai yawa (e.g., kawo karshe, hoton sama). Kowane lokacin da ake tabbatar da abin, ya kamata a yi takamfa da ci gaba ko karkashin gida.
