Karamin Yawan Daukan Da Tsakiyar Waje

Karamin yawan da tsakiyar waje ita ce babban nasara a cikin tashoshin kawar da tsabta, wanda ya nuna rashin aikinsu (sifili/yanayi), rashin amfani da shiga, harsunan gurbin kaya, da yanayi. Idan an rasa yawa, tsakiyar kashi ya zama mai tsayi (babu kashi na da tsakiya don iya haɗa da EMF na mafi tsakiya), wanda ya ba da satoci, kashefan alamun magana, da yanayi/yanayin lafiya.

Dalilai sun hada da sauran fushi, rashin amfani, ko nasarar mutum. A cikin tashoshin kawar da tsabta, tsakiyar waje ta haɗa da meters/kashefan inganci (tsayin kashi, ya danganta da sifili). Idan an rasa yawan da tsakiya, ya zama yawan da tsakiya—misali, fushen da suka tsaya a fushen 10kV substation ya ba da yawan da tsakiya, aikinsu, da rashin amfani da shiga.

Don in baka: Kafin gaba, ka ƙoƙarin kashefan amfani. Tuntubi fushi/joints (gire kashi na tsakiya ta da multimeter). Baka yawan da tsakiya a ƙananan tsari. Zama tsakar da tsakiya a matsayin bayyana (ba a yi da ma'ana da lokaci).

Karamin Yawan Ingantacciyar Rambuwa

Yawan ingantacciyar rambuwa ita ce babban nasara, wanda ya ba da tsayin shiga fushi na tsayi, shiga na gida, yanayi, ko hoton kayan adagga. An samu dalilan abinci, tsaya, dust, ko rashin inganta (wadannan suna daɗe ingantacciyar rambuwa kamar epoxy resin, silicon steel, ko paper).

Epoxy resin ya samu tsayin abinci a lokacin da yake da abinci da tsayi (95% RH, 65℃), wanda ya zama tsayin kashi daga 1.57×10¹⁵Ω·cm zuwa 5.21×10⁴Ω·cm. Dust da yanayi sun zama masu zamani da suke daɗe.

Misali: Tashoshin kawar da tsabta 10kV ya zama yawan da tsakiya saboda yawan da tsakiya (ingantaccin da ba da ma'ana), wanda ya zama tsayin kashi da shiga fushi na tsayi.

Inganci: Yi aiki da tsarin ingantacciyar rambuwa (>1MΩ, 2500V megohmmeter don 10kV PTs). Ƙare kan fitila, tabbatar da ƙungiyar kashi na ɗaya. Don tashoshin da suke da abinci: misalai da ƙarin daɗe za a yi hoton daɗen abinci; misalai da ƙarin daɗe za a yi ƙungiyar abinci ko koyar da ingantacciyar rambuwa.

Karamin Yawan Daɗe

Yawan daɗe ya ba da rashin aikinsu, rashin amfani, da rashin amfani. Kafin JJG314-2010, yawan daɗe suna da wata ƙananan 25%-100% rated secondary load. Amfani da kashi da ƙarin daɗe (da ƙarin daɗe/da ƙarin daɗe) sun ba da yawan daɗe.

Dalilai sun hada da kashi na tsakiya, tsayin kashi na daɗe, rashin amfani, ko ingantaccin da ke tsayi. Misali, ƙungiyar kashi 10kV da ƙarin daɗe ya ba da yawan daɗe >0.5%.

Don in baka: Tuntubi ƙungiyar kashi (tabbatar da amfani). Gire girman ƙungiyar kashi; koyar da ƙungiyar kashi idan ana buƙata. Ƙoƙari yawan daɗe (koyar da shi idan ƙoƙarin ba zama ba).

Karamin Yawan Inganta

Yawan inganta (girman ƙungiyar, fushi na tsakiya, ƙungiyar kashi) suna da wata inganta, rashin amfani, ko yanayi. Misali, tashoshin kawar 10kV ya zama yawan daɗe saboda yanayi, wanda ya ba da aikinsu da yawan daɗe.

Inganci: Amfani da fitilolin da suke ƙoƙari (honeycomb cardboard + polyurethane foam) a lokacin da a yi ƙungiyar (ƙoƙarin daɗe da ƙungiyar kashi zuwa ˂1mm). Ƙungiya kamar yadda aka ambaci, tuntubi ƙungiyar kashi daɗe.

Karamin Yawan Ƙungiyar Kashi Na Ɗaya

Yawan ƙungiyar kashi na ɗaya ya ba da rashin aikinsu, rashin amfani. Tashoshin kawar da tsabta suna da wata ƙungiyar kashi na ɗaya; ƙungiyar kashi na ɗaya sun ba da kashi na ƙungiyar.

Dalilai sun hada da ingantaccin da ba da ma'ana, ƙungiyar kashi da ƙarin daɗe, ko rashin amfani. Misali, ƙungiyar kashi B/C phase auxiliary windings a 10kV substation ya haɗa da ƙungiyar kashi, wanda ya ba da shiga fushi, da rashin amfani.

Don in baka: Nemo da koyar da ƙungiyar kashi na ɗaya (tabbatar da ƙungiyar kashi ɗaya). Tuntubi ƙungiyar kashi. Gire kashi daga UN zuwa ground bar na protection panel (≈0Ω yana nuna ƙungiyar kashi na ɗaya).
