1. Inhloso kanye nezinhlobo zei-transformerukunakekela
a.Inhloso yokugcinwa kwe-transformer
Inhloso eyinhloko yokugcinwa kwe-transformer ukuqinisekisa ukuthi i-transformer nezinsiza 'ngaphakathi nangaphandle izingxenyezigcinwa zisesimweni esihle, “zilungele injongo” futhi zingasebenza ngokuphepha noma nini.Okubaluleke ngokufanayo ukugcina irekhodi lomlando wesimo se-transformer.
b.Amafomu okulungisa i-Transformer
Ama-transformer kagesi adinga imisebenzi ehlukahlukene yokulungisa okujwayelekile, okuhlanganisa ukukala nokuhlola amapharamitha e-transformer ahlukene.Kunezinhlobo ezimbili eziyinhloko zokulungiswa kwe-transformer.Senza iqembu elilodwa ngezikhathi ezithile (okuthiwa ukugcinwa kokuvikela) kanye nelesibili ngendlela engavamile (okungukuthi, lapho kudingeka).
2. Ukuhlola Ukugcinwa Kwe-Periodic Transformer yanyanga zonke
- Izinga lamafutha ku-cap yamafutha kufanele lihlolwe njalo ngenyanga ukuze lingabi ngaphansi komkhawulo omisiwe, futhi ngaleyo ndlela umonakalo obangelwa yilo ugwenywe.
- Gcina izimbobo zokuphefumula eshubhuni yokuphefumula yejeli yesilika ihlanzekile ukuze uqinisekise ukuphefumula okufanele.
- Uma wakhoi-transformer yamandlainezihlahla zokugcwalisa amafutha, qiniseka ukuthi amafutha agcwaliswa ngendlela efanele.
Uma kunesidingo, amafutha azogcwaliswa e-bushing ezingeni elifanele.Ukugcwaliswa kwamafutha kwenziwa esimweni sokuvala.
3. I-Daily Basis Maintenance and Checking
– Funda i-MOG (I-Magnetic Oil Meter) yethangi elikhulu nethangi lokugcina.
- Umbala wejeli yesilika emphefumulweni.
- Amafutha avuza kunoma iyiphi indawo ye-transformer.
Uma kwenzeka izinga likawoyela elingagculisi ku-MOG, amafutha kufanele agcwaliswe ku-transformer, futhi ithangi lonke le-transformer kufanele lihlolwe ukuvuza kwamafutha.Uma kutholakala ukuvuza kwamafutha, thatha isinyathelo esidingekayo ukuze uvale ukuvuza.Uma ijeli ye-silica iba pink kancane, kufanele ishintshwe.
4. Isheduli eyisisekelo yokulungisa i-transformer yonyaka
- Umsebenzi ozenzakalelayo, oqhelile, futhi owenziwe ngesandla wesistimu yokupholisa kusho ukuthi amaphampu kawoyela, abalandeli bomoya, nezinye izinto zokusebenza zijoyina uhlelo lokupholisa i-transformer kanye nesifunda sokulawula.Bazohlolwa isikhathi esingangonyaka.Uma kwenzeka ukungasebenzi kahle, phenya isifunda sokulawula nesimo somzimba sephampu nefeni.
- Wonke amahlahla e-transformer kumele ahlanzwe ngendwangu kakotini ethambile minyaka yonke.Ngesikhathi sokuhlanzwa kwe-bushing kufanele kuhlolwe ukuqhekeka.
- Isimo sikawoyela se-OLTC sizohlolwa minyaka yonke.Ngakho-ke, isampula likawoyela lizothathwa kuvalvu yokukhipha amanzi ethangini eliphambukayo, futhi lesampula kawoyela eqoqiwe izohlolelwa amandla e-dielectric (BDV) kanye nomswakama (PPM).Uma i-BDV iphansi, futhi i-PPM yomswakama ingaphezulu kwevelu enconyiwe, uwoyela ongaphakathi kwe-OLTC udinga ukushintshwa noma uhlungwe.
- Ukuhlolwa Mechanical of Buchholzamalayidiokumele lwenziwe minyaka yonke.
- Zonke izitsha kufanele zihlanzwe ngaphakathi okungenani kanye ngonyaka.Wonke amalambu, izifudumezi zasemkhathini ziyahlolwa ukuze kubonakale ukuthi zisebenza kahle yini.Uma kungenjalo, kufanele uthathe isinyathelo sesondlo.Zonke izixhumi zetheminali zokulawula kanye nezintambo ezidluliswayo kufanele zihlolwe ukuthi ziyaqina okungenani kanye ngonyaka.
- Wonke ama-relay, ama-alamu, namaswishi okulawula kanye namasekhethi awo, kumaphaneli e-R&C (Control Panel and Relays) kanye ne-RTCC (Remote Tap Change Control Panel), kufanele ahlanzwe ngokuhlanzwa okufanele.
- Amaphakethe e-OTI, i-WTI (isikhombi sezinga lokushisa likawoyela nesikhombi sezinga lokushisa ikhoyili) akukhava engaphezulu ye-transformer ukuze ahlolwe, uma uwoyela edingeka.
- Umsebenzi ofanele weDivaysi Yokukhipha Ingcindezi kanye ne-Buchholz relay kumele ihlolwe minyaka yonke.Ngakho-ke, oxhumana nabo bohambo abangenhla nabathintwayo be-alamu bafushaniswa ngocingo oluncane futhi babheke ukuthi ingabe ukudluliselwa okuhlobene kuphaneli yesilawuli kude kusebenza kahle yini.
- Ukumelana nokufakwa kwe-transformer kanye nenkomba ye-polarity kuzobhekwa nge-megger esebenza ngebhethri engu-5 kV.
- Inani lokumelana nokuxhunywa komhlaba kanye neriza kufanele kukalwe ngonyaka nge-clamp kumitha yokumelana nomhlaba.
- I-DGA noma ukuhlaziywa kwegesi encibilikisiwe kawoyela we-transformer kufanele kwenziwe minyaka yonke kuma-transformer angu-132 kV, kanye eminyakeni emi-2 kuma-transformer angaphansi kuka-132 kV, iminyaka emibili kuma-transformer ku-132 kV transformer.
Isinyathelo okufanele sithathwe kanye njalo eminyakeni emibili:
Ukulinganiswa kwe-OTI ne-WTI kufanele kwenziwe kanye njalo eminyakeni emibili.
I-Tan & delta;Ukukalwa kwezihlahla ze-transformer kuzokwenziwa kanye njalo eminyakeni emibili
5. Ukugcinwa kwe-transformer ingxenye yeminyaka
I-transformer yakho yamandla idinga ukuhlolwa njalo ezinyangeni eziyisithupha ukuze ibone i-IFT, i-DDA, i-flash point, okuqukethwe kwe-sludge, i-acidity, okuqukethwe kwamanzi, amandla e-dielectric, kanye nokumelana nowoyela we-transformer.
6. Ukugcinwa kweI-Transformer yamanje
Ama-transformer amanje ayingxenye ebalulekile yanoma yimuphi umshini ofakwe esiteshini sokuguqula amandla ukuze uvikele futhi ulinganise ugesi.
Amandla okufakwa kwe-insulation of the CT kumele ihlolwe minyaka yonke.Enqubweni yokulinganisa ukumelana nokufakwa kwe-insulation, kufanele kukhunjulwe ukuthi kunamazinga amabili okushisa kuma-transformers amanje.Izinga lokwahlukanisa le-CT eyinhloko liphezulu uma kuqhathaniswa, njengoba kufanele limelane ne-voltage yesistimu.Kodwa i-CT's yesibili inezinga eliphansi lokwehlukanisa ngokuvamile elingu-1.1 kV.Ngakho-ke, okuyisisekelo kuya kwesibili futhi okuyisisekelo emhlabeni wama-transformer amanje alinganiswa ngama-megger angu-2.5 noma angu-5 kV.Kodwa le megger ephezulu kagesi ayikwazi ukusetshenziselwa izilinganiso zesibili njengoba izinga lokufakwa liphansi uma liqhathaniswa nombono wezomnotho wedizayini.Ngakho-ke, ukufakwa kwesibili kukalwa ku-500 V megger.Ngakho, itheminali yokuqala yomhlaba, itheminali eyinhloko eya kumongo wokulinganisa wesibili, kanye netheminali eyinhloko eya kunkambo yesibili evikelayo kukalwa ngama-megger angu-2.5 noma angu-5 kV.
Ukuskena kombono we-thermo wamatheminali ayisisekelo kanye nedome eliphezulu le-CT ephilayo kufanele kwenziwe okungenani kanye ngonyaka.Lokhu kuskena kungenziwa ngosizo lwekhamera ye-Infrared Thermal Surveillance.
Konke ukuxhumana kwesibili kwe-CT ebhokisini lesibili le-CT kanye nebhokisi lokuhlangana kwe-CT kufanele kuhlolwe, kuhlanzwe, futhi kuqiniswe minyaka yonke ukuze kuqinisekiswe indlela ephansi yokumelana ne-CT yesibili.Futhi, qiniseka ukuthi ibhokisi le-CT junction lihlanzwa ngendlela efanele.
Imikhiqizo ye-MBT Transformer
7. Ukugcinwa kwaminyaka yonke kwe-i-voltage transformers noma i-capacitor voltage transformers
Isembozo se-porcelain kufanele sihlanzwe ngezingubo zikakotini.
Ukuhlanganiswa kwe-spark gap kuzobhekwa njalo ngonyaka.Susa ingxenye enyakazayo yegebe lenhlansi lapho uhlanganisa, hlanza i-electrode yobhodisi nge-sandpaper, bese uyilungisa endaweni yayo.
Iphoyinti eliphansi le-High-frequency grounding kufanele lihlolwe ngokubukeka njalo ngonyaka uma kwenzeka inkinga ingasetshenziselwa i-PLCC.
Amakhamera okubona ashisayo asetshenziselwa ukuhlola noma yiziphi izindawo ezishisayo kuzitaki ze-capacitor ukuze kuqinisekiswe isenzo sochwepheshe sokulungisa.
Ibhokisi le-PT junction lokuxhumana kwetheminali liqukethe ukuxhumana okuphansi okuhlolelwa ukuqina kanye ngonyaka.Ngaphandle kwalokho, ibhokisi le-PT junction kufanele futhi lihlanzwe kahle kanye ngonyaka.
Isimo sawo wonke amalunga e-gasket kufanele futhi ahlolwe ngokubonakalayo futhi ashintshwe uma kutholakala izimpawu ezonakele.
