Muhimmanci na Hanyar Tabbatar da H59 Oil Immersed Power Distribution Transformer Daga Yauzance

A cikin kungiyoyin kashi, H59 Oil Immersed Power Distribution Transformer ta yi matsayin muhimmanci sosai. Idan yauza ne, zan iya haifar da yawan kashi na yau da kullum, wanda ya tabbatar da shi ko kuma yadda aka sa shi. Saboda binciken abubuwan da suka faruwa a cikin hanyoyin yauzance, mai rubutu ya nuna cewa mafi yawan hanyoyin yana iya zama da ba da tsawon kan ko kuma da gaba da kusa a lokacin da ake magana da muhimman hanyoyin.

1. Bincike Ta Kadan Da H59 Oil Immersed Power Distribution Transformer

Don haka don in taimakawa cewa H59 Oil Immersed Power Distribution Transformer ya zama daidai don amfani da shi da kuma in taimakawa da yauzance, ya kamata a yi bincike ta kadan a cikin gidaje. Abubuwan da za a yi bincike sun hada da:

• Bincike cewa takarfin ruwa a cikin tanki na konservasiya ya fi dace da kuma cewa takarfin ruwa ya daidai. Idan takarfin ruwa ya fi karfi, ya kamata a yi yanayi saboda jiki idan an sanya transformer da ladabi. Idan takarfin ruwa ya fi kafuwa, ya kamata a yi yanayi saboda ya fi kafuwa a wasu lokutan a ranar harshe ko kuma lokutan da aka sanya transformer da ladabi na kafuwa, wanda zai haifar da kyaukyau da kuma kyanwa na transformer da kuma ya tabbatar da aiki.

• Bincike cewa takun, bushings, takarfin ruwa, valves na kudin ruwa, da sauransu na da kyau da kuma babu kudin ruwa. Idan haka ba da shi, ya kamata a yi yanayi saboda ya fi karfi da kudin ruwa a lokacin da transformer ya samu ladabi.

• Bincike cewa diaphragm na explosion-proof (explosion vent) ya fi dace.

• Bincike bushings don kaza, kasa, ko kuma alamomin kasa.

• Tabbatar da cewa desiccant (silica gel) a cikin breather (silica gel canister) ya fi dace.

• Tabbatar da cewa grounding na tanki na transformer ya fi dace da kuma ya fi dace.

• Bincike cewa primary da secondary bushings da kuma dabbarin da suka rasa da conductors ya fi dace da kuma cewa makarantar rangi ya daidai.

• Tabbatar da cewa data na nameplate ta daidai da specifications na transformer da ke bukata, ciki har da voltage ratings a duk ciki, winding connection group, rated capacity, da kuma tap changer position.

• Amfani da megohmmeter na 1,000–2,500 MΩ don in bincike resistance na insulation na both primary da secondary windings to ground da kuma between windings. Rufe temperature na yawan harkokin lokaci. Idan ban da standard na rigide don acceptable insulation resistance values, measured values ya kamata a yi kawo da historical ko factory data da kuma ya kamata ba zama da 70% da original value ba.

• Amfani da ohmmeter don in bincike DC resistance na transformer windings together with bushings. Don distribution transformers, difference between phase DC resistances ya kamata a kasance da less than 4% of the average value, da kuma difference between line-to-line DC resistances ya kamata a kasance da less than 2% of the average value.

• Bincike cewa selection na fuses ya daidai. Primary-side fuse ya kamata a kasance da 1.5–2 times the transformer’s rated current, da kuma secondary-side fuse ya kamata a kasance da secondary rated current.

Idan duk binciken da suka faruwa, ya kamata a sanya transformer da ba da ladabi ba (“cold energization”). A lokacin da wannan test, bincike cewa electromagnetic noise ba da shi ko kuma measure whether the secondary voltages are balanced. Balanced voltages na nuna cewa turns ratio ya daidai da kuma absence of inter-turn short circuits, wanda ya tabbatar da transformer ya zama daidai don amfani da ladabi.

2. Muhimmanci na Amfani na H59 Oil Immersed Power Distribution Transformer

• A lokacin da amfani, bincike regularly cewa three-phase voltages ya daidai. Idan ka neman significant imbalance, yi actions immediately. Kuma bincike regularly takarfin ruwa da color, da kuma check the tank for oil leaks. Yi corrections promptly don in taimakawa da tap changers ko kuma windings ba su yauze saboda moisture ingress.

• Safi dirt and contaminants from the transformer surface regularly. Bincike bushings for flashover or discharge, verify good grounding, and check for broken, poorly soldered, or fractured grounding conductors. Measure ground resistance periodically—ensuring it does not exceed 4 Ω for transformers ≥100 kVA or 10 Ω for transformers <100 kVA—or implement anti-pollution measures such as installing pollution-resistant bushing caps.

• A lokacin da ake kofa ko kuma sanya transformer leads, follow inspection and installation procedures strictly to avoid internal conductor breakage. Select appropriate connection methods for secondary conductors.

• A lokacin da ake install surge arresters on both primary and secondary sides of the H59 Oil Immersed Power Distribution Transformer, connect the arrester grounding lead, transformer tank, and secondary neutral point to a common grounding point. Conduct regular preventive tests and promptly replace any defective arresters to reduce the risk of overvoltage damage caused by lightning or resonance.

• A cikin mutanen karamin tashin tabbacin da ba da shiga yanayi, kaɗa gano rayuwar DC duk wanda ba da shiga yanayi, rasa hanyoyin, kuma samar da ukuwa masu DC don inganta. Kawai sake amfani da tranzista ba ta haka lokacin da aka da shakka cewa an yi shiga yanayi daidai. A cikin gano rayuwarsa tun duka wurare, ya kamata a rasa littattafan da suka da shiga yanayi a cikin karni.

• Sanya harkokin nemo da kula da aiki a cikin yankin da ke ƙarfafa. Sake fadada tranzista a yankunan da ke ƙarfafa don kuɗi abin da ke ƙarfafa da za su iya haifar da aiki.
