Kanan da ya fi kawo lokaci na ƙarfin giniwa ga maimaitaccen hanyoyi na 110 kV

Salamu da zurfi, ina Echo, na yi aiki a cikin voltage transformers (VTs) tafi 12 shekau.

Daga lokacin da na bar azumi kan bayan aiki a cikin insulation tests zuwa yanzu na ji aiki masu kula-kula game da matsalolin voltage equipment — na yi aiki da oil refilling sosai. Yana da muhimmanci wajen yanayin voltage transformers na 110 kV, amma ba shi ne abin da ya yi lokaci da rike da haka.

A ranar guda, mutum minkali ya tufinani:

“Echo, har da lokacin da a yi oil refill a cikin VTs na 110 kV, ana iya haɗa da biyu ko biyu shekaru. Ana yi da tsawon lokaci. Ina iya samun hanyar zama aiki ta kasance?”

Wannan bincike ne mai ma'ana! Saboda haka, na fahimtar yanzu:

Yadda za a iya sanar da lokacin da ake yi oil refill a cikin voltage transformers na 110 kV? Ina da hanyar da suka dace ko kyau?

Babu wasu kalmomi masu ilimi — basu magana da aiki a cikin tarihin 12 shekau. Tafara da ka fara!

1. A Muhimmanci: Me Ya Yi Lokacin Da Oil Refill?

Wasu masu nuna cewa oil refill shi ne kawai a lura hose da kuma fitar da valve. Amma a cikin tsawon abubuwa, akwai wasu batutuwan da ke yi lokacin da ake yi aiki:

• Koyar da ruwa mai tsarki saboda air blockage;

• Vacuum mai tsarki, wanda ke jin ruwa a zama da ita;

• Hukumar da ake yi da kiyaye gravity feed;

• Nemawa masu tsafta da ke jin aiki a tsawo.

Waɗannan suna da shi a yi lokacin da ake yi aiki.

Saboda haka, idan kana son sanar da lokacin, kana buƙata da a yi amfani da aikin da kuma kayan aiki.

2. Hukumomin Daban-Daban + Hanyoyin Da Za Su Sanar Da Lokacin

Hanyar #1: Yi Vacuum Pre-Treatment — Ba Taka Bisa Da Ruwa Ta Koma Da Ka Faru!

Wasu masu nuna cewa ake kasa ruwa daɗi, sannan ake faru vacuum, sannan ake kara ruwa — wadannan suna iya haɗa da biyu shekaru.

Zan iya bincika wannan:

Faru vacuum a lokacin, sama da duk system na ruwa — hoses, valves, hatta VT daɗinsu.

Idan ruwa mai gaba ya kama, ka fitar da valve da kake kara ruwa — babu taka baki.

Pro Tip: Amfani da machine da ke yi oil filling da vacuum — yana iya kara ruwa a lokacin da ke faru vacuum, wanda ke sanar da lokacin da yake!

Hanyar #2: Zabe Kayan Aiki — Ba Taka Bisa Da Pumps Masu Kiyaye!

Oil filling da kiyaye ba shi ne kawai laifi — ba shi ne kuma tana iya kasa bubbles da air a cikin system.

Yanzu, akwai electric vacuum oil filling machines wadanda suka da muhimmanci:

• Built-in vacuum pump — vacuum da kara ruwa a lokacin;

• High flow rate — zan iya kara ruwa a lokacin da yake;

• Tana da oil filtration — tana taimakawa da a tsafta impurities a lokacin.

Akwai mutane da suka ci gaba da aiki, amma a lokacin da yake, suka sanar da lokacin, laifi, da kuma tsafta. Tana da ma'ana daidai!

Hanyar #3: Zabe Design Na Path Na Oil — Ba Taka Bisa Da Air!

A lokacin da yake, ba shi ne ruwa mai tsarki — shi ne air wanda ke jin blockages.

Ina da shi a yi:

• Fitar da air vent valve daɗinsu idan a faru;

• Amsa ruwa daga karamin, tare da air a ɗaukan — yana da shi a yi smooth flow;

• Idan akwai multiple ports, amfani da lower one first.

Wannan yana taimakawa da ruwa a yi smooth flow bila bubbles ko clogs — da yake yana sanar da lokacin.

Hanyar #4: Test Quality Na Ruwa Idan A Faru — Ba Taka Bisa Da Ganin!

Babu abu da ya fi yawa da a yi oil refill, sannan a ganin cewa ruwa ba shi da standards — kamar dielectric strength mai tsarki ko moisture content mai yawa. Sannan ake kasa ruwa da kake faru a gaba.

Don haka, za a iya:

Test quality na ruwa idan a faru, sama da:

• Breakdown voltage;

• Moisture content;

• Color and odor check.

Idan ruwa ya da standards, sannan ka faru. Wannan yana taimakawa da a tsafta rework a gaba.

Hanyar #5: Standardize Process & Team Up — Ba Taka Bisa Da Ganin!

Oil refilling ba shi ne aiki mai kiyaye. Abubuwa masu ma'ana suna nuna cewa:

• Mutum minkali ya kunshi pressure da level na ruwa;

• Mutum minkali ya kunshi valve da machine na ruwa;

• Mutum minkali ya rubuta data da kuma ya kawo hoton aiki;

• Mutum minkali ya kunshi emergency support.

Idan akwai plan da coordination, aiki yana zama daidai — da kuma daidai.

3. Finafin

Idan na yi aiki a cikin wannan field tafi 10 shekau, wannan ne ina neman:

“Oil refilling ba shi ne aiki da kiyaye — shi ne aiki da hanyar daidai. Mutum da take da ma'ana yana iya kara a 10 minutes; amma mutum da ba shi da ma'ana yana iya haɗa da lokacin.”

Idan kana da hukumomin da suka da tsawo, ya kamata a zabe kayan aiki da aikin.

Ya kamata waɗannan abubuwa masu muhimmanci:

• Faru vacuum a lokacin;

• Amfani da efficient oil filling equipment;

• Zabe design na path na oil;

• Test oil idan a faru;

• Aka da team daidai da workflow daidai.

Waɗannan suna sanar da lokacin, amma suna taimakawa da a tsafta risk na failure na kayan aiki.

Idan kana da abubuwa a lokacin da ake yi oil refilling — kamar pressure ba shi da tsayi, bubbles da sauransu, ko ruwa ba shi da karɓar da aiki — zan iya taimaka. Ina son in ba da shawarwari da kuma hanyoyin da suka dace.

Ina yi aiki don haka da cewa kowane voltage transformer yana yi aiki daidai, daidai, da kuma daidai — taimakawa da power grid daidai!
