1. Inhloso kanye nezinhlobo zei-transformerukuhlalisa
a. Inhloso yokulungiswa kwe-transformer
Inhloso eyinhloko yokulungiswa kwe-transformer ukuqinisekisa ukuthi i-transformer nezesekeli 'zangaphakathi nangaphandle izingxenyezigcinwa zisesimweni esihle, "zilungele inhloso" futhi zingasebenza ngokuphepha nganoma yisiphi isikhathi. Okubaluleke ngokulinganayo ukugcina umlando we-Transformer simo.
b. Amafomu wokugcina ama-transformer
Ama-Power Transformers adinga imisebenzi ehlukahlukene yokulungisa ejwayelekile, kufaka phakathi ukulinganisa nokuhlola amapharamitha we-transformer ahlukene. Kunezindlela ezimbili eziyinhloko zokulungiswa kwe-transformer. Senza iqembu elilodwa ngezikhathi ezithile (okubizwa ngokuthi ukugcinwa kokuvimbela) kanye nokwesibili ngokwesisekelo (ie, ekufuneni).
2. Isheke lesondlo lenyanga yenyanga yenyanga
- Izinga lamafutha ku-cap cap kumele lihlolwe njalo ngenyanga ukuze lingaweli ngaphansi komkhawulo olungiselelwe, futhi ngaleyo ndlela ukulimala okubangelwa yilokho kugwenywa.
- Gcina izimbobo zokuphefumula eSilica Gel Breathing tube zihlanzekile ukuqinisekisa imisebenzi efanele yokuphefumula.
- Uma eyakhoI-Power TransformerIgcwalisa amafutha e-bush, qiniseka ukuthi uwoyela ugcwaliswa kahle.
Uma kunesidingo, uwoyela uzogcwaliswa ezihlahleni ezingeni elifanele. Ukugcwaliswa kwamafutha kwenziwa esimweni sokuvalwa.
3. Isisekelo sansuku zonke kanye nokuhlola
- Funda mog (imitha kazibuthe yamafutha) yethangi elikhulu nethangi lokugcina.
- Umbala wejeli ye-silica emoyeni.
- Ukuvuza kawoyela kusuka kunoma yiliphi iphuzu le-transformer.
Uma kwenzeka kuba nenqanaba kawoyela elingagculisi ku-mog, uwoyela kumele ugcwaliswe ku-transformer, futhi ithangi lonke le-transformer kufanele ihlolwe ukuvuza kawoyela. Uma kutholakala ukuvuza kwamafutha, thatha isenzo esidingekayo sokufaka uphawu lokuvuza. Uma ijeli ye-silica iba pink kancane, kufanele ithathelwe indawo.
4. Isheduli yesondlo ebalulekile yonyaka
- The okuzenzakalelayo, okukude, kanye nomsebenzi owenziwa ngesandla wohlelo lokupholisa kusho ukuthi amaphampu kawoyela, abalandeli bomoya, kanye neminye imishini ujoyina uhlelo lokupholisa iTransformer kanye ne-Control Circuit. Bazohlolwa isikhathi esingaphezu konyaka owodwa. Uma kwenzeka ungasebenzi kahle, phenya umjikelezo wokulawula kanye nesimo somzimba sephampu kanye nomlandeli.
- Onke ama-transformer bushings kumele ahlanzwe ngendwangu yekotini ethambile ngonyaka. Ngesikhathi sokuhlanza i-bushing kufanele kuhlolwe imifantu.
- Isimo samafutha se-OLTC sizohlolwa njalo ngonyaka. Ngakho-ke, isampula kawoyela izothathwa kusuka ku-valve ye-drain yethangi eliphambukayo, futhi leli sampula kawoyela eliqoqiwe lizohlolelwa amandla we-dielectric (BDV) kanye nomswakama (ppm). Uma i-BDV iphansi, futhi i-PPM yomswakama iphakeme kunenani elinconyiwe, i-oyili ngaphakathi kwe-OLTC idinga ukushintshwa noma ukuhlunga.
- Ukuhlolwa kwemishini kweBuchholzbuyisaukwenziwa njalo ngonyaka.
- Zonke iziqukathi kufanele zihlanzwe kusuka ngaphakathi okungenani kanye ngonyaka. Zonke izibani, ama-Space Heater ahlolwe ukuze abone ukuthi asebenza kahle yini. Uma kungenjalo, kufanele uthathe isenzo sokulungisa. Konke ukuxhumeka okubulalayo kokulawula nokudluliselwa kwe-wiring ukuze ihlolwe ngokonakala okungenani kanye ngonyaka.
- Konke kudluliselwa, ama-alamu, kanye nokulawula ukushintshwa kanye nemijikelezo yawo, ku-R & C (Iphaneli Yokulawula Ukudluliselwa) ne-RTCC (Remote Change Speciver Control Panel) kanye ne-RTCC
- Amaphakethe we-OTI, i-WTI (Inkomba yokushisa kawoyela & inkomba yokushisa yamakhoyili) kwikhava ephezulu yeTransformer izohlolwa, futhi uma kudingeka uwoyela.
- Umsebenzi ofanele wedivayisi yokukhishwa kwengcindezi kanye nokudluliswa kweBuchholz kumele kuhlolwe minyaka yonke. Ngakho-ke, amadivaysi angenhla 'oxhumana nabo be-Trip kanye noxhumana nabo be-alamu bafinyezwa yingxenye encane yocingo bese bebona ukuthi ukudluliselwa okuhlobene nephaneli yokulawula kude kusebenza kahle.
- Ukumelana nokuvinjwa kwe-Transformer's Insulation kanye ne-Polarity Index kuzohlolwa nge-megger esebenza ngebhethri le-5 KV.
- Inani lokumelana nomhlabathi kanye ne-rizer kumele lilinganiswe minyaka yonke nge-clamp emathamitha wokumelana nomhlaba.
- I-DGA noma ukuhlaziywa kwegesi okuncibilikisiwe kwamafutha e-transformer kufanele kwenziwe minyaka yonke ku-132 KV Transformers, kanye eminyakeni emi-2 ye-Transformers ngaphansi kwe-132 kV, iminyaka emibili yabaguquli ku-132 kV transformer ku-132 kV transformer ku-132 kV transformer ku-132 kV transformer ku-132 kV transformer ku-132 kV transformer on 132 kV transformer.
Isenzo okufanele sithathwe kanye njalo eminyakeni emibili:
Ukulinganisa kwe-OTI ne-WTI kumele kwenziwe kanye njalo eminyakeni emibili.
Tan & delta; Ukulinganiswa kwama-transformer bushings kuzokwenziwa kanye njalo ngonyaka
I-5. Ukulungiswa kwe-Transformer ngesigamu sesigamu
I-Power Transformer yakho idinga ukuhlolwa njalo ezinyangeni eziyisithupha nge-IFT, DDA, i-Flash Point, okuqukethwe kwe-sludge, okuqukethwe kwe-acidge, okuqukethwe kwamanzi, amandla e-dielectric.
6. Ukulungiswa kweUmshini wamanje we-transformer
Abaguquli bamanje bayingxenye ebalulekile yanoma iyiphi imishini efakwe esiteshini se-Power Transformer ukuvikela nokukala ugesi.
Amandla okufakwa kwe CT kumele ihlolwe minyaka yonke. Enqubweni yokulinganisa ukumelana kokufakelwa, kufanele kukhunjulwe ukuthi kunamazinga amabili okufakwa ku-transformers yamanje. Izinga lokufakwa kwe-CT eyinhloko liphakeme kakhulu, ngoba kufanele likwazi ukumelana nogesi wohlelo. Kepha ama-CT wesibili anenqanaba eliphansi lokufakelwa ngokujwayelekile ka-1.1 kV. Ngakho-ke, okuyisisekelo kuya kwesekondari futhi okuyisisekelo emhlabeni we-transformers yamanje kulinganiswa kuma-megger angama-2,5 noma ama-5. Kepha leli voltage eliphakeme alikwazi ukusetshenziselwa izilinganiso zesibili ngoba izinga lokufakelwa liphansi kakhulu kusuka endaweni yezomnotho yezomnotho. Ngakho-ke, ukufakwa kwesibili kukalwa ngo-500 v megger. Ngakho-ke, ukuphela okuyisisekelo emhlabeni, ukuphela okuyinhloko kuya engxenyeni yesibili yokulinganisa, futhi i-terminal eyinhloko eya endaweni eyisisekelo evikelayo ilinganiswe kuma-megger angama-2,5 noma ama-5.
Ukuskena kombono we-thermo kwama-terminals aphambili kanye ne-dome ephezulu ye-CT ebukhoma kufanele yenziwe okungenani ngonyaka. Le scan ingenziwa ngosizo lwekhamera yokubhekisisa ye-infrared thermal.
Konke ukuxhumeka kwesibili kwe-CT ebhokisini lesibili le-CT ne-CT genction ibhokisi kufanele kuhlolwe, kuhlanzwa, futhi kuqiniswe minyaka yonke ukuze kuqinisekiswe indlela ephansi yokuphikiswa kwe-CT Secondary. Futhi, qiniseka ukuthi ibhokisi le-genction le-CT lihlanzwa kahle.
Imikhiqizo ye-MBT Transformer
7. Ukulungiswa konyaka kweI-Voltage TransformerI-S noma iCapacitor Voltage Transformers
Isembozo se-porcelain kumele sihlanzwe ngezingubo ukotini.
Umhlangano wegebe le-Spark uzohlolwa minyaka yonke. Susa ingxenye eshukumisekayo ye-Spark Gap lapho uhlangana, hlanza i-electrode ye-braes nge-sandpaper, bese uyilungisa emuva.
Iphoyinti elivelele eliphakeme kakhulu kufanele lihlolwe njalo ngonyaka uma kwenzeka inkinga ingasetshenziselwa i-PLCC.
Amakhamera we-Thermal Vision asetshenziselwa ukubheka noma yiziphi izindawo ezishisayo eCapacitor Stacks ukuqinisekisa isenzo sokulungisa.
Ukuxhumeka kwe-terminal PT Junction Box kuqukethe ukuxhumana komhlaba okuhlolwe ukuqina kanye ngonyaka. Ngaphandle kwalokho, ibhokisi le-PT Junction kumele futhi lihlanziwe kahle kanye ngonyaka.
Isimo sawo wonke amalunga we-gasket kufanele futhi sihlolwe ngamehlo futhi sithathelwe indawo uma izimpawu ezilimele zitholakala.
