Na Bincike Masu Amfani Da Kisan Tashin Yawan Kirkiro Daga 110kV: Inganci Da Gaskiya

Yadda na Kula Tsarin Maimakon Da Duk 110kV

A cikin tattalin karamin zabe, maimakon da duka suna muhimmanci wajen mamaye zabe daga hankali mai yawa. Don yanayi da ke 110kV ko kadan—kamar 35kV ko 10kV sub-stations—yadda na kula tsarin maimakon ta hanyar harkokin zai yi girma wajen iya gaba haske da ya faruwa kan hankalin karamin zabe. Zaman lafiya wannan yadda ce ita ce amfani da teknologi na harkokin zai don inganta halittukan maimakon ba tare da kawo karshen tattalin karamin zabe.

Sassan yadda na kula ce ta hanyar ci gaba masu kula, tana bincika kungiyar kula mai yawa don inganta tsakanin maimakon da ya rage ko da shaida. Iccen duniya na IEC 60099-4 ta nuna abubuwan da aka bukata don kula maimakon, ta ambaci cewa harkokin zai masu kula daidai shine muhimmanci don inganta zaman lafiya. An ambaci da kuma iccen kasar China GB 11032 wajen nuna abubuwan da za su iya kula maimakon a cikin tattalin karamin zabe da ke 110kV ko kadan.

Abubuwan da za su iya kula sun haɗa da transformarun kula (CTs) da zaman lafiya, wahon da ke aiki da kula data, da kuma bayanan labaran. CT yana buƙatar da amsa da yawa a fadin daɗi, da ta ƙunshi 50 Hz zuwa 1 MHz, don inganta abubuwan da ke daɗi. Wahon da ke aiki da kula data yana buƙatar da siffofin da za su iya kula a cikin fadin daɗi, tare da kula signal da zaman lafiya. Bayanan labaran ta ƙunshi alamomin labari—kamar Fourier transform analysis—don kula asali kula mai yawa. Kula aikin za su iya kula tun da aiki, da ta kusa a shekarar, da kula aikin da ta fi tsauri da tsarin standard, tare da kula aikin da ya fi tsauri da ±1%. Masu aiki suna buƙatar da samun tashehin karamin zabe da lafiya da kuma sanin aikin bayanan labaran don iya kula aiki da lafiya.

Tashin aiki ta faruwa da tashin yanayin. Zaka zaka maimakon da za su iya kula, da ta ƙunshi yanayin da ba da sauya da kuma babban hankalin mai yawa. Idan an sama wahon da ke aiki da kula data, duba jirgin kula ta hanyar CT, bude bayanan labaran, da kuma kula parametos kamar 1 kHz sampling rate da 5-minutun lokacin kula. A lokacin da aki shiga, system ta hanyar zama da kula asali kula mai yawa. A lokacin kula, masu aiki suna duba kungiyoyi da za su iya kula abubuwan da ke daɗi. Daga bakin kula data, fitowa raw files; bayanan labaran ta hanyar zama da kula report da take ƙunshi peak resistive current, fundamental component, da kuma harmonic analysis. Har zuwa a cikin tashin kula, kaɗannan za su iya kula tafasa da kula timestamp, tempuraturin yanayin, da kuma humidity.

Zaman lafiya suna da muhimmanci. Duba tashin risk assessment idan aiki ya faru, tana bincika abubuwan da ke daɗi kamar electric shock da arc flash. Sami aiki da kuma sami da aiki da kula insulating gloves, goggles, da kuma flame-resistant clothing. Kafa tashin lafiya da kula warning tape da “High Voltage Test” signs; masu aiki da ba suka duba tashin aiki ba za su iya kula. Daɗe da aiki da kula safe distances—minimum 1.5 meters for 110kV systems. Emergency preparedness includes fire extinguishers and first aid kits; if anomalies occur, immediately cut power and report. According to Article 40 of China’s Occupational Safety Law, enterprises must provide employees with no less than eight hours of annual safety training. Quality control requires test errors within ±2%, and repeated measurements must not deviate by more than 1%.

Kula results ta hanyar software-generated report. Resistive current da ya kai da baseline da 10% yana nuna cewa maimakon ya rage da kuma yana buƙatar da kula replacement; abnormal harmonic content suggests internal moisture or contamination. Report interpretation combines historical data to assess trends. For example, in a 35kV substation case, initial resistive current was 50μA, rising to 60μA after one year—prompt replacement prevented failure. Non-conforming results trigger maintenance workflows: complete a defect record form and notify operations teams for resolution within 48 hours. Data must be archived for at least five years for audit purposes.

Wannan yadda na kula ce ta hanyar zai yi girma wajen iya kula maimakon, da ta kusa kula 90% lokaci kadan da traditional disassembly-based testing da kuma kula haske da ya faruwa kan hankalin karamin zabe. Enterprises should establish annual plans, conducting tests quarterly to ensure system reliability. Continuous improvement includes adopting wireless transmission for remote monitoring. Successful implementation requires staff training to enhance technical proficiency. In summary, this method provides an efficient and safe solution for evaluating surge arresters in power systems at 110kV and below.
