Me kadan da ake nufin a Zaba da Yawancin GIS Current Transformers?

Salam mai girma, ina James, na yi aiki da current transformers (CTs) shekara 10. Gadan ya zan iya hada game da abubuwa masu muhimmanci a kan zabi da kuma fitar da GIS current transformers.

Babu 1: Abubuwa Muhimmanci a Kan Zabi
1. Kalamiyar Zuruwarsa

• CTs Protection-grade: Ana amfani da su don hanyar rambursa — tana bincika da kyau zuwa aikin gina da ci gaba da tashin yawan jihohi.

• CTs Metering-grade: Ana amfani da su don magangan bayanai — ana bukatar zuwa da shaida, yawanci kalamin 0.2S ko 0.5S.

2. Aikin Yakin Tsari

Zabi da shaida a cikin aikin yakin tsari mai karfi, tare da wata wurin mutum domin ya ba tabbacin aikin da za a yi da rike mafi tsawon lokaci.

3. Masana'antu

Yakin da CT ta dogara da abubuwan masana'antu ga tsarin kirkiyarsa, musamman don tashin yanayin tsari.

4. Tattalin Yanayin Ingantaccen Yanki

Zabi models da suke dogara da ingantaccen yanayin yanki kamar yawan hawa, jiha, ko takalma — nemo materials da ke da aikin takalma ko special coatings.

5. Manyan Kwayoyi

Akwai kwayoyi da ke da GIS equipment, saboda haka dogara da shaida cewa CT ta fi son sama da kowane component baya.

Babu 2: Abubuwan Bayanai Muhimmanci Don Fitar
1. Tabbata Da Bayanan Mai Sarrafa

Fitar da shaida kamar yadda aka bayyana a manual. Ya kamata a lura wata wurin mutum yana da shiga, amma zai iya haɗa da matsaloli a gaba.

2. Grounding

Tsari na biyu yana da kyau a grounding da shaida don haɗe aiki a kan voltage mai haɗa. Bicirka primary-side grounding kuma.

3. Tabbatar Da Sealing

Saboda GIS ta amfani da gas SF6, sealing mai kyau ita ce muhimmi. Tabbata da shaida flanges da joints kafin fitar — wanda kula mai yawa zai iya haɗa da matsaloli mai zurfi.

4. Tashin Masana'antu Ba Da Fitar

Yi tashin resistance masana'antu ba da fitar don haka maka a nan da shaida up to standard — wannan ita ce muhimmi a cikin yanayin jiha.

5. Commissioning & Calibration

Ba da fitar:

• Dogara da polarity;

• Yi tashin ratio;

• Tabbatar da connections na biyu;

• Yi tashin load na rubuce-rubuce don tabbatar da aiki.

6. Tabbatar Da Dust & Contamination

A cikin fitar, fada parts da suke duba da protective covers don haɗe dust ko debris suka shiga.

Babu 3: Farkon Lura

Na sami ne a wannan sarautar shekara 10, wannan ita ce na nufi:

“Zabi da fitar da GIS current transformers ba ita ce kaɗan kaɗan — an buƙata da tattalin yanayin da shaida.”

Idan ka samu matsaloli a kan zabi ko fitar, za a iya kawo shugabanar da shaida. Ina jin daurin ya bayar waɗannan tattalin yanayin da shaida da kuma bayanan aiki.

Ina yi shugabanar da cewa duk GIS current transformer yana yi aiki da shaida da kalmomi!
