Wani Abubuwa a Yi Amfani Da Su Don Tashin Karamin Ƙananan Turanci na 35kV

Don samun karamin hankali da kula da ƙungiyar jirgin magana na 35kV, zan iya amfani da tarihin kasuwanci masu yawan karfi:

Samun Karamin Hankali na Tsakiyar

Amfani da abubuwa kamar tsakamai na takarduka, ma'adin bayanin gurbin lutsen watsa, da yanayin samun karamin hankali na tsakiyar. Idan an samu cewa tsakiyar da ke ɗaya ya fi ɗauki 1000MΩ ko tsakiyar da take da ɗauke tanδ ya fi ɗauki 0.5%, yana buƙata a yi rarrabe da ƙungiya da ƙarin inganci. Don abubuwan SF₆, za a iya samun cewa an samu cewa akwai gas ta fuskantar da ake amfani da yanayin samun karamin hankali na fara mai zurfi ko yanayin samun karamin hankali na zafi.

Samun Karamin Hankali na Tattalin Ferromagnetic

Idan an samun cewa akwai tattalin ferromagnetic, za a iya samun shi daga tushen bayanai game da ƙaramin hankali (3U₀) da kuma ƙaramin hankali na uku (3U₀) da kuma tashin ƙaramin hankali na uku. Idan an samu cewa ƙaramin hankali na 3U₀ ya fi ɗauki ko ƙaramin hankali na uku suka ɗauki, yana buƙata a duba cewa akwai tattalin ferromagnetic. Duk da cewa, za a iya samun risalansa na tattalin ferromagnetic don tushen bayanai game da ƙaramin hankali (kamar tashin tsakiyar da take da ɗauke da tsakiyar da take da ɗauke) da kuma tushen bayanai game da ƙarfin ƙungiya (kamar tashin tushen bayanai game da ƙarfin ƙungiya).

Samun Karamin Hankali na Tattalin Electromagnetic

Amfani da abubuwan samun karamin hankali na electromagnetic compatibility don samun karamin hankali na ƙungiyar jirgin magana. Abubuwan kamar samun karamin hankali na partial discharges tare da capacitive coupling, samun karamin hankali na wurin da ake fito da ultrasonic waves, da kuma samun karamin hankali na tsari tare da infrared thermal imaging za su iya samun darajar da take da ɗauke na tattalin electromagnetic. Don ƙungiyar jirgin magana a cikin GIS, za a buƙata a samun karamin hankali na high-frequency transient electromagnetic waves da ke ɗauki zuwa low-voltage acquisition units.

Samun Karamin Hankali na Vibration Na Makaranta

Amfani da acceleration sensors don samun karamin hankali na vibration waveforms da kuma samun karamin hankali na abnormal frequencies tare da spectrum analysis. Tare da tushen bayanai game da standard vibration signals, za a iya samun cewa akwai vibration da ke ɗauki saboda partial discharge ko mechanical structural looseness. Duk da cewa, za a iya amfani da infrared temperature measurement don samun karamin hankali na local overheating da ke ɗauki saboda poor contact da ke ɗauki saboda vibration.

Samun Karamin Hankali na Secondary Circuit

Tambayata ƙaramin hankali na secondary fuses, samun karamin hankali na resistance na secondary circuits, da kuma samun karamin hankali na abnormal instrument indications. Idan an samu cewa secondary fuse na phase batu ce ya fi ɗauki, za a iya samun cewa ƙaramin hankali na voltmeter, power meter, da sauransu na phase batu ce ya fi ɗauki; idan an samu cewa akwai open circuit a cikin secondary circuit, za a iya samun cewa akwai loud "buzzing" sound da kuma abnormal instrument indications, da kuma za a iya rarraba ƙungiya don ƙarin inganci. Duk da cewa, za a iya amfani da partial discharge measurement don samun karamin hankali na discharge phenomena da ke ɗauki saboda abnormalities na secondary circuit.

Samun Karamin Hankali na Calibration da Load-Related

Amfani da three-phase calibration system don apply three-phase voltage da current, simulate actual working conditions, da kuma samun karamin hankali na measurement performance na ƙungiyar jirgin magana. Tare da tushen bayanai game da error differences between the single-phase method and the three-phase method, za a iya samun darajar da take da ɗauke na tattalin electromagnetic interference on measurement accuracy. Duk da cewa, za a iya amfani da infrared temperature measurement don samun karamin hankali na abnormal temperature rises da ke ɗauki saboda overload.

Samun Karamin Hankali na Gas Leakage na SF₆

Amfani da abubuwan kamar infrared imaging leak detectors, wavelet analysis signal processing systems, da kuma pressure monitoring devices don samun karamin hankali na sealing performance na abubuwan SF₆. Infrared imaging leak detection za a iya samun cewa akwai leak points, while wavelet analysis za a iya samun cewa akwai micro-leaks. Don abubuwan SF₆ da suka ɗauki gas leakage, za a iya rarraba ƙungiya don ƙarin inganci.
