Karamin kariyar fuskashin hanyar yin gudunmawa: "Tafin ruwa" na transformer mai ƙarfi a cikin ruwa

Karamin kariyar fuskashin hanyar yin gudunmawa don kincina mai shafa da kaiyayi yana ɗaukar da matsalarta ta hanyar tsayayyen da ke kuma a cikin yadda transformer na elektrisiti zai iya aiki da kuma kariya. Yadda transformer zai iya aiki yana tattaunawa sosai da yadda jijjiyar oil-paper insulation system ya faru, kuma thermal aging ce abu ne na yawa da ke cika kariya na insulation. Don hakan, don kowace lokaci da insulation material ya aiki ta ƙasa daga yadda ta kafa shi a cikin yadda, yadda ta jijjiya zai tattara sosai. Don hakan, kariya mai yawa na kariya zai iya kare yadda hotspot temperature na windings - wanda ne abu ne na yawa don gano yadda transformer ya aiki da kuma yadda ya kashe.

Idan watsawar zafi ba shi da kyau, kuma zafin jiki na ciki ya yi yawa, ba wai kawai zai hanzarta lalacewar man fetur mai rufi da kayan rufi mai ƙarfi ba, rage aikin rufi, amma kuma yana iya haifar da gazawar kayan aiki har ma ya shafi daidaitaccen aiki na dukkanin wutar lantarki. Za a iya cewa kyakkyawan watsawar zafi shine muhimmin abin da ake buƙata don tabbatar da cewa mai canzawa zai iya aiki lafiya da kwanciyar hankali a ƙarƙashin nauyin ƙididdiga kuma ya isa rayuwarsa ta tsara (yawanci har zuwa shekaru 30 ko fiye).

Mahimman abubuwan da ke shafar watsawar zafi na transformaɗa mai kaiyayyaci

Ingancin watsawar zafi na masu rarraba mai mai rarraba mai amfani da man fetur shine sakamakon sakamakon haɗin gwiwar zirga-zirgar mai da kuma iska. Babban abubuwan da ke tasiri wannan tsari za a iya bincika su daga manyan fannoni biyu: yanayin kwararar mai na ciki da yanayin sanyaya na waje.

1. Tsarin mai na ciki da tsarin tsari sune tushen watsa zafi.

A cikin lokacin amfani da transformer, ƙauna wanda ake samun daga windings da core tana zama zuwa heat sink ta hanyar natural ko forced convection na insulating oil. Bayani suka nuna cewa yadda oil flow ya gudan, yana da tasiri mai mahimmanci ga temperature rise: lokacin da oil flow speed ya kara daga 0.05 m/s zuwa 0.20 m/s, ƙananan temperature na core zai iya kara kusa ta 11.62 K. Tsarin oil channel na gaba ce kuma babu kamar yadda ke cika shi. Kada kadan horizontal oil channels ko sao kadan oil-blocking plates a yadda da ke cika shi zai iya tabbata kariya na circulation a wadanda yawa daga oil flow wanda ba su gudan, kuma yana kara kusa temperature na windings.

2. Hanyar external cooling da shawara na environment suna fahimta efficiency na heat dissipation.

Matsayin kula suka kashe a matsayin tashin yadda suka yi kula: kula ta hanyar zai (ONAN), kula ta hanyar hawaye (ONAF), da kula ta hanyar zai mai tsanani (OFAF). Kula ta hanyar hawaye zai iya saita ƙarfin kula da 150% zuwa 200% don kula ta hanyar zai. Amma, idan yadda hawaye ya fi gaba, yadda kula ya fi kara, da kula ta hanyar zai zai fi kara kuma yana fi kara mafi kyau. Kuma matsayin muhimman suna kuma ci gaban kula ta hanyar zai, kamar yadda ake sanya kusurun da suka cire kula ta hanyar zai don kula ta hanyar zai, kuma yana kara kula ta hanyar zai da 10.6 K.

A wasu kalmar, kula ta hanyar zai na transformer zai bukatar kula ta hanyar zai, kula ta hanyar zai, da kula ta hanyar zai, don kula ta hanyar zai da kula ta hanyar zai, kuma yana kara kula ta hanyar zai da kula ta hanyar zai.

Yaya za a gano kula ta hanyar zai na transformer?

Don tantance ko aikin sanyaya ya cika ka'idoji, akwai wasu hanyoyi da suka fara daga tabbatarwa na yau da kullum zuwa saka idanu kan layi:

1. Ƙaƙwalwar gwajin zafin jiki (kafin masana'anta da kuma aiki):

Wannan shi ne babban ma'auni na kimantawa. Bisa ga ka'idodin ƙasa, ta hanyar kwaikwayon nauyin ƙididdiga, auna yawan zafin jiki na kowane ɓangare na mai canzawa (bambanci tsakanin zafin jiki da yanayi), kuma tabbatar da cewa bai wuce iyakar da aka ƙayyade ba. Gwajin zai mai da hankali kan lura da haɓakar zafin jiki na man fetur na saman da zafin jiki na zafi na windings, wanda shine mabuɗin don ƙayyade ko ƙirar sanyaya ta cancanta.

2. Kula da yanayin aiki (aikin yau da kullum):

Don masu canzawa masu aiki, ana iya amfani da hanyoyi masu zuwa don kimantawa:

• Kula da zafin jiki: Kula da zafin jiki na saman man fetur shine hanya mafi mahimmanci. Yawan zafin jiki mai yawan gaske yana nuna raguwar ingancin tsarin sanyaya.

• Tattaunin karamin fahimta na ƙarfi: Ta hanyar bayanin tashin karamin fahimta, ta yamatar algorizam na ingilizanci, za a iya gano karamin fahimta na yanzu na ƙarfi daga bayanan amfani kamar karamin fahimta da karamin fahimta na zaki, don hankalci wajen karamin fahimta na karamin fahimta.

• Tattaunin karamin fahimta na infrared: Ta yamatar karamin fahimta na infrared don shiga karamin fahimta na transformer da karamin fahimta za a iya gano lokaci na karamin fahimta ko karamin fahimta na karamin fahimta.

3. Tattaunin karamin fahimta na bayanan karamin fahimta na karamin fahimta:

Idan a nuna karamin fahimta na karamin fahimta, za a iya gano karamin fahimta na karamin fahimta, kamar yin karamin fahimta na karamin fahimta na karamin fahimta don gano karamin fahimta na karamin fahimta na karamin fahimta, ko yin karamin fahimta na karamin fahimta na karamin fahimta don gano karamin fahimta na karamin fahimta na karamin fahimta.

Ta hanyar waɗannan hanyoyin kimantawa na yau da kullun, ana iya fahimtar yanayin sanyaya na mai canzawa, yana ba da damar gano matsaloli a kan lokaci da aiwatar da matakan kulawa.
