1. Inhloso kanye nezinhlobo zei-transformerukulungiswa
a. Inhloso yokunakekelwa kwe-transformer
Inhloso eyinhloko yokunakekelwa kwe-transformer ukuqinisekisa ukuthi i-transformer kanye nezesekeli zangaphakathi nezangaphandle izingxenyezigcinwa zisesimweni esihle, “zilungele injongo” futhi zingasebenza ngokuphephile noma nini. Okubaluleke ngokulinganayo ukugcina umlando wesimo se-transformer.
b. Amafomu okulungisa ama-transformer
Ama-transformer kagesi adinga imisebenzi ehlukahlukene yokulungisa ejwayelekile, okuhlanganisa ukukala nokuhlola amapharamitha e-transformer ahlukene. Kunezinhlobo ezimbili eziyinhloko zokulungisa ama-transformer. Senza iqembu elilodwa ngezikhathi ezithile (elibizwa ngokuthi ukulungiswa kokuvimbela) kanye nelesibili ngendlela ekhethekile (okungukuthi, uma kudingeka).
2. Ukuhlolwa Kokulungiswa Kwesiguquli Esihlala Njalo Kwanyanga Zonke
– Izinga likawoyela esivimbelweni sikawoyela kumele lihlolwe njalo ngenyanga ukuze lingaweli ngaphansi komkhawulo omisiwe, ngaleyo ndlela umonakalo odalwe yiwo ugwenywe.
- Gcina izimbobo zokuphefumula epayipini lokuphefumula le-silica gel zihlanzekile ukuqinisekisa ukusebenza kahle kokuphefumula.
- Umaisiguquli samandlainezihlahla ezigcwalisa uwoyela, qiniseka ukuthi uwoyela ugcwaliswe kahle.
Uma kudingeka, uwoyela uzogcwaliswa ebhodweni kuze kufike ezingeni elifanele. Ukugcwaliswa kwamafutha kwenziwa esimweni sokuvala.
3. Ukulungiswa Nokuhlolwa Kwansuku Zonke
– Funda i-MOG (i-Magnetic Oil Meter) yethangi eliyinhloko kanye nethangi lokugcina.
- Umbala wejeli ye-silica ephefumulayo.
- Ukuvuza kwamafutha kusuka kunoma iyiphi indawo ye-transformer.
Uma kwenzeka izinga likawoyela elingagculisi ku-MOG, uwoyela kumele ugcwaliswe ku-transformer, futhi lonke ithangi le-transformer kumele lihlolwe ukuthi alivuzi yini uwoyela. Uma kutholakala ukuvuza kukawoyela, thatha isinyathelo esidingekayo ukuvala ukuvuza. Uma ijeli le-silica liba pinki kancane, kufanele lishintshwe.
4. Uhlelo lokunakekelwa oluyisisekelo lwaminyaka yonke lwe-transformer
– Umsebenzi ozenzakalelayo, osebenza kude, kanye nowesandla wesistimu yokupholisa usho ukuthi amaphampu kawoyela, amafeni omoya, kanye neminye imishini ijoyina uhlelo lokupholisa lwe-transformer kanye nesekethe yokulawula. Kuzohlolwa isikhathi esiyiminyaka eyodwa. Uma kwenzeka ukungasebenzi kahle, hlola isekethe yokulawula kanye nesimo somzimba sepompo kanye nefeni.
- Zonke izikhonkwane ze-transformer kumele zihlanzwe ngendwangu ethambile yekotoni minyaka yonke. Ngesikhathi sokuhlanza isikhonkwane kufanele kuhlolwe ukuthi azinamifantu yini.
- Isimo samafutha se-OLTC sizohlolwa minyaka yonke. Ngakho-ke, isampula yamafutha izothathwa ku-valve yokukhipha amanzi yethangi elihlukanisayo, futhi le sampula yamafutha eqoqwe izohlolwa amandla e-dielectric (BDV) kanye nomswakama (PPM). Uma i-BDV iphansi, futhi i-PPM yomswakama iphakeme kunenani elinconywayo, uwoyela ongaphakathi kwe-OLTC udinga ukushintshwa noma ukuhluzwa.
- Ukuhlolwa kwemishini kweBuchholzukudluliselwaokumele kwenziwe minyaka yonke.
- Zonke izitsha kumele zihlanzwe ngaphakathi okungenani kanye ngonyaka. Zonke izibani, ama-heater endawo ayahlolwa ukuze kubonakale ukuthi asebenza kahle yini. Uma kungenjalo, kufanele uthathe isinyathelo sokulungisa. Zonke izixhumanisi ze-terminal zokulawula kanye nezintambo zokudlulisa kufanele zihlolwe ziqine okungenani kanye ngonyaka.
- Wonke ama-relay, ama-alamu, kanye namaswishi okulawula kanye namasekethe awo, kumaphaneli e-R&C (Control Panel and Relays) kanye ne-RTCC (Remote Tap Change Control Panel), kufanele ahlanzwe ngokuhlanzwa okufanele kwezinto.
- Amaphakethe e-OTI, i-WTI (inkomba yokushisa kwamafutha kanye nenkomba yokushisa kwekhoyili) esembozweni esiphezulu se-transformer okumele ihlolwe, nokuthi ngabe uwoyela uyadingeka yini.
- Umsebenzi ofanele weDivaysi Yokukhulula Umfutho kanye ne-Buchholz relay kumele uhlolwe minyaka yonke. Ngakho-ke, oxhumana nabo be-trip kanye ne-alamu yamadivayisi angenhla bafinyezwa yingcezu encane yocingo bese bebheka ukuthi ama-relay ahlobene yini kuphaneli yokulawula kude asebenza kahle.
- Ukumelana nokushisa kwe-transformer kanye ne-polarity index kufanele kuhlolwe nge-megger esebenza ngebhethri elingu-5 kV.
- Inani lokumelana kokuxhumeka komhlaba kanye ne-rizer kumele kulinganiswe minyaka yonke nge-clamp kumitha yokumelana komhlaba.
- Ukuhlaziywa kwegesi ye-transformer ye-DGA noma encibilikisiwe kufanele kwenziwe minyaka yonke kuma-transformer angu-132 kV, kanye eminyakeni emi-2 kuma-transformer angaphansi kuka-132 kV, iminyaka emibili kuma-transformer aku-transformer engu-132 kV.
Isinyathelo okufanele sithathwe kanye njalo eminyakeni emibili:
Ukulinganiswa kwe-OTI kanye ne-WTI kumele kwenziwe kanye njalo eminyakeni emibili.
I-Tan & delta; Ukulinganiswa kwama-bushing e-transformer kufanele kwenziwe kanye njalo eminyakeni emibili
5. Ukulungiswa kwe-transformer ngesisekelo sesigamu sonyaka
I-power transformer yakho idinga ukuhlolwa njalo ezinyangeni eziyisithupha ukuthola i-IFT, i-DDA, i-flash point, okuqukethwe yi-sludge, i-acidity, okuqukethwe kwamanzi, amandla e-dielectric, kanye nokumelana ne-transformer oil.
6. Ukugcinwa kweI-Transformer Yamanje
Ama-transformer amanje ayingxenye ebalulekile yanoma iyiphi imishini efakwe esiteshini sokuguqula amandla ukuze kuvikelwe futhi kulinganiswe ugesi.
Amandla okuvikela uthuli CT kumele ihlolwe minyaka yonke. Enqubweni yokulinganisa ukumelana nokufakwa kokushisa, kumelwe kukhunjulwe ukuthi kunezinga ezimbili zokufakwa kokushisa kuma-transformer amanje. Izinga lokufakwa kokushisa le-CT eyinhloko liphezulu kakhulu, njengoba kumele limelane ne-voltage yesistimu. Kodwa ama-CT esibili anezinga eliphansi lokufakwa kokushisa ngokuvamile elingu-1.1 kV. Ngakho-ke, okuyisisekelo kuya kwesibili kanye nokuyinhloko kuya emhlabeni kwama-transformer amanje kulinganiswa ngama-megger angu-2.5 noma angu-5 kV. Kodwa lokhu kuhlanganiswa kwamandla aphezulu akukwazi ukusetshenziselwa ukulinganisa okwesibili njengoba izinga lokufakwa kokushisa liphansi kakhulu ngokombono wezomnotho womklamo. Ngakho-ke, ukufakelwa kwamandla okwesibili kulinganiswa ngama-megger angu-500 V. Ngakho-ke, i-terminal eyinhloko eya emhlabeni, i-terminal eyinhloko eya enkabeni yokulinganisa yesibili, kanye ne-terminal eyinhloko eya enkabeni yesibili evikelayo kulinganiswa ngama-megger angu-2.5 noma angu-5 kV.
Ukuskena kwe-thermo vision kwama-terminals ayinhloko kanye ne-dome ephezulu ye-CT ephilayo kufanele kwenziwe okungenani kanye ngonyaka. Lokhu kuskena kungenziwa ngosizo lwe-Infrared Thermal Surveillance Camera.
Zonke izixhumanisi ze-CT secondary box ze-CT secondary box kanye ne-CT junction box kumele zihlolwe, zihlanzwe, futhi ziqiniswe minyaka yonke ukuqinisekisa ukuthi indlela yokumelana ne-CT secondary ephansi kakhulu iyasebenza. Futhi, qiniseka ukuthi ibhokisi le-CT junction lihlanzwa kahle.
Imikhiqizo ye-MBT Transformer
7. Ukugcinwa kwaminyaka yonke kwei-transformer ye-voltageama-s noma ama-capacitor voltage transformers
Isembozo se-porcelain kumele sihlanzwe ngezingubo zikakotini.
Ukuhlanganiswa kwesikhala se-spark kuzohlolwa minyaka yonke. Susa ingxenye enyakazayo yesikhala se-spark lapho uhlanganisa, hlanza i-electrode ye-braes nge-sandpaper, bese uyilungisa kabusha endaweni yayo.
Indawo yokumisa imvamisa ephezulu kufanele ihlolwe ngokubonakalayo minyaka yonke uma inkinga ingasetshenziswanga i-PLCC.
Amakhamera okubona ukushisa asetshenziswa ukuhlola noma yiziphi izindawo ezishisayo kuma-capacitor stacks ukuqinisekisa isenzo sobuchwepheshe sokulungisa.
Ukuxhumeka kwetheminali Ibhokisi le-PT junction liqukethe ukuxhumeka komhlaba okuhlolwe ukuqina kanye ngonyaka. Ngaphandle kwalokho, ibhokisi le-PT junction kumele lihlanzwe kahle kanye ngonyaka.
Isimo sazo zonke izihlanganisi ze-gasket kufanele sihlolwe ngamehlo futhi sishintshwe uma kutholakala izivalo ezonakele.
