Bincike na Tsarin Karamin Kirkiro na Raba

Wannan bincike yana nuna idan an zama masu kofin shiga suka iya daidaita tsari na kirkiro na raba daban-daban.

Bincike na Isulai

Tsarin karamin kirkiro na raba ya fi yake da tsari na kirkiro na raba saboda abubuwa daban-daban, kamar hanyoyi na ziyarka ko kungiyoyin tap changer. Binciken tsarin karamin kirkiro na raba yana nuna idan isulai na masu kofin shiga yana iya daidaita wannan tsari. Masu kofin shiga suna bukata suke daidaita tsari na kirkiro na raba da kuma tsari na kirkiro na yadda. Amma a nan mafi girman cin bayan inganci, ma'aikatar sana'ar masu kofin shiga suna bukata cewa za su iya daidaita masu kofin shiga a cikin kudin.

Don in nuna idan masu kofin shiga zai iya daidaita tsari na kirkiro na raba a cikin kudin, yawancin binciken isulai suna bukata suke daidaita. Amma ne binciken tsarin karamin kirkiro na raba wanda ke ana sanar da shi a matsayin makaranta na tattaunawa masu kofin shiga.

Bincike na Tsarin Karamin Kirkiro na Raba ta Faduwar Daɗi 60 Daga Biyu

Ana kira cewa tsari na kirkiro na raba ba za a yi faduwar daɗi 60 daga biyu, amma a nan yana kasancewa ita a lokacin da ita ya faru. Wannan bincike yana daidaita idan isulai da aka bayar a cikin masu kofin shiga yana iya daidaita tsari na kirkiro na raba a faduwar daɗi 60 daga biyu.

A yi wannan bincike a faduwar daɗi 60 daga biyu. Tsari na karamin kirkiro na raba, wadanda ake bayar a cikin masu kofin shiga a lokacin binciken, ana bayyana a kan standard kamar hukumar da take samu tsari na system.

Misalai na bincike na tsarin karamin kirkiro na raba ta faduwar daɗi 60 daga biyu shine masu kofin shiga SF6. A yanzu, yawan takwas na duka poles na masu kofin shiga da take da tsari na raba masu sama suna kofin da kable na copper da kuma earthed. Yawan babbari suna earthed kuma yawan kasa suna kofin da kable na copper.

Wannan kofin yana kofin da phase terminal na high voltage cascaded transformer. High voltage transformer wanda ake amfani da shi shine cascaded auto transformer inda input voltage zai iya canzawa daga zero zuwa murubbin volts da kuma secondary voltage zai iya canzawa daga zero zuwa murubbin kilo volts.

A lokacin bincike, voltage zai bayar a button terminal na masu kofin shiga tun daga high voltage cascaded transformer, kuma zai canza daga 0 zuwa hukumomin da aka bayyana har zuwa 60 daga biyu, sannan zai ci 0. A lokacin bincike, leakage current zuwa ground zai ci, kuma leakage current ba zai iya haɗa da maximum allowed limit. Idan isulai ta rage a lokacin bincike, yana nuna cewa isulai da aka bayar a cikin masu kofin shiga ba daidai ba.

Bincike na Isulai na Circuits na Auxiliary da Control

Za a iya samu tsari na kirkiro na raba a circuits na auxiliary da control supply, kuma haka, circuits na auxiliary da control na masu kofin shiga suna bukata suke daidaita binciken tsarin karamin kirkiro na raba ta faduwar daɗi 60 daga biyu. A nan, test voltage na 2000 V zai bayar don faduwar daɗi 60 daga biyu. Isulai na circuits na auxiliary da control zai bukata suke daidaita wannan bincike, kuma ba zai iya samu destructive discharge a lokacin binciken.

Yawan Zabe na Resistance na Main Circuit

Resistance na main circuit zai zabe daga DC voltage drop across the circuit. A wannan binciken, direct current zai injekta a cikin circuit, kuma voltage drop zai zabe, kuma resistance na circuit zai zabe. Injekta current zai iya haɗa da 100 A zuwa maximum rated current na masu kofin shiga. Maximum measured value zai iya haɗa da 1.2 times the value obtained at the temperature rise test.

Bincike na Tightness

Wannan bincike zai yi a gas insulated switch-gear. A wannan binciken, leakage rate zai zabe. Wannan bincike zai inganta tsari na switchgear. Haka, duka jointing points a gas containing paths zai kofin air tightly da thin sheets of polythene (preferably transparent) zuwa 8 hours, sannan gas density inside this covers zai zabe tun daga gas detecting port of a gas detector through a hole now created on the covers. The measurement zai ci a ppm unit and should be within the specified limit. Maximum limit of gas leakage 3 ppm / 8 hours, is taken as standard.

Binciken Visual

Masu kofin shiga suna bukata suke bincika visual don language and data on the templates, proper identification mark of any auxiliary equipment, color and quality of paint and corrosion on metallic surface, etc.

Operation na Mechanical

Masu kofin shiga suna bukata suke bincika operation na mechanical a levels daban-daban, including rapid auto-reclosing capabilities.

Binciken Masu Kofin Shiga

Binciken masu kofin shiga sun hada da binciken visual, resistance measurement, and ensuring airtightness to maintain performance and safety.
