I-bushing engenamanzi ye-oyile-intywiliselweisitshintshiyinxalenye esetyenziswa ngokuqhelekileyo.Ingaba i-oil-transformer-immersed-immersed transformer okanye i-oyile-test-immersed transformer, wonke umntu ubona olu hlobo lwecandelo ngaphandle kwe-oil-immersed transformer.Namhlanje, wonke umntu uya kunika isingeniso esicacileyo kwiinkalo ezimbini eziphambili zeempawu kunye nokusebenza kakuhle, kwaye enze ukwandiswa kwempendulo: Ngokubhekiselele kwi-casing engenamanzi, kukho ngokubanzi iindidi ezimbini ze-capacitive sensors kunye ne-non-capacitive, kunye ne-rerated current. hayi ngaphantsi kwe-35kV.Chwetheza isingxobo esingangenwa manzi Ityhubhu ngokuqhelekileyo yonke i-capacitive sensor casing waterproof.Kutheni lahlulwe kangaka?Isizathu esona sizathu kukuba izinto zabo zihluke, kwaye i-voltage yokusebenza enokuthi iqhutywe iyahluka.

Ke ngoko, oku kunabela kwintshayelelo yakho eneenkcukacha ekusebenzeni kwei-oyile-intywiliselwe i-transformeramatyholo angangeni manzi:

1. Ukusebenza kakuhle

I-casing engenamanzi isoloko ifuna ukuthwala i-voltage yokusebenza, kuba ukujika kufuneka kuxhomekeke kwi-casing yokungena kwamanzi ukuba idibaniswe ne-oyile ye-oyile ye-oyile ye-transformer.Ngoko ke, ukuba i-casing engenamanzi ihlala iphosakele, i-oyile-i-transformer entywiliselweyo ayiyi kusebenza ngokukhawuleza.Iimpazamo eziqhelekileyo Isenokuba ngenxa yeengozi zomlilo, njl.

Masiyitolike ngokucacileyo apha ngezantsi: itanki ye-fuel ye-oil-transformed-oil-immersed transformer yenziwe ngentsimbi kwaye inesixhobo sokumisa.Intambo yomhlaba we-transformer yesilonda inokudibaniswa kuphela kwigridi yamandla ngokwetanki yeoli;kunye nocingo olusezantsi lwe-transformer yesilonda kufuneka ludibaniswe kwitanki yeoli ngoncedo lwe-casing engenamanzi.I-bushing engenamanzi iyingxenye yocingo lomhlaba we-transformer ejikelezayo kwaye iyinxalenye yesekethe ejikelezayo.

2. Intshayelelo eneenkcukacha yeempawu:

Ngokuqhelekileyo, iimpawu ze-casing engangeni manzi ukubaioli-transformerabavelisi be-oyile-bafake i-transformer banenkxalabo malunga nokusebenza kwe-insulation kunye neempawu ze-thermal.Ezi zenzo zimbini zinokumisela ukuthembeka komsebenzi wakhe kwaye ziqinisekise ukusebenza okungaqhelekanga kweziphumo zakhe.Oku kulandelayo Mandazise ezi ngongoma zimbini zincinci:

A. Ukusebenza kwe-insulation A. Iimpawu ezibalulekileyo zomgangatho wangaphakathi we-insulating.Ukusebenza okubalulekileyo kwe-insulation ye-capacitive sensor waterproof casing ingachazwa: umsebenzi obalaseleyo wokutywina, akukho kuvuza kwamanzi;inqanaba lokukhupha inxalenye engaphantsi kwe-10pC;stable.

B. Iimpawu ezibalulekileyo zomaleko we-insulating wangaphandle.Uluhlu lwangaphandle lwe-insulating ye-casing waterproof lubhekiselele kwi-insulating layer ye-outland layer ye-casing waterproof kunye ne-air contact part, kunye neoli okanye i-SF.Umaleko wangaphandle ochukunyiswa ngumphunga awungowomaleko wokugquma wangaphandle.Uphawu olubalulekileyo lwe-insulation yangaphandle ye-sleeve ye-porcelain kukuba umgama we-creepage we-sleeve engenamanzi uhambelana nenqanaba lokungcola kwendawo yesicelo, kwaye kukho umda.

(2) Iimpawu zobushushu

A. Iimpawu ze-Thermal zabaqhubi abakhoyo ngoku.Umsebenzi we-thermal we-conductor ophetheyo ngoku kukukhokela ngokuthe ngqo izibonda, iintambo kunye neebhloko ze-terminal ukuba ngaba kunokwenzeka ukuvelisa ubushushu obuphezulu xa ixesha elide lokusebenza lisekelwe kwixabiso elilinganisiweyo okanye ixesha elifutshane lokusebenza. ngokusekelwe kwisixa se-overcurrent.Ukufudumeza kwekhebula okanye intonga yokuqhubela phambili ihambelana nokuqina okukhethiweyo kwangoku, kwaye akukho ziphoso eziqhelekileyo eziye zenzeka xa umbane olinganisiweyo usetyenziswa.Ukunyuka kweqondo lobushushu kwibhloko yetheminali kunxulumene nezinto ezahlukeneyo ezifana nobunzulu obubonakalayo bangoku, umgangatho wokugquma (kubandakanya ukucakwa kwetin, ukucakwa kwegolide, njl.njl.), kunye nokuqinisa amandla.Isiphoso esiqhelekileyo sokushisa okugqithisileyo kwibhloko ye-terminal ngokuqhelekileyo ayikho ingxaki yesakhiwo esibangelwa uxhulumaniso olungekho semgangathweni, kodwa ngokwenene lubangelwa ngumsebenzi wangempela ngexesha loxhumo.

B. Iimpawu ze-Thermal ze-insulating layer ye-core casing core.Uvavanyo lweempawu ze-thermal zomaleko wokugquma we-casing core ye-casing core ibizwa ngokuba luvavanyo lokumelana nobushushu ngomgangatho welizwe loshishino.Ngethuba lovavanyo, i-casing engenamanzi ifakwe kwi-oyile-ifakweisitshintshii-oyile kwi-(90 ± 2) ℃, kunye nobudlelwane obunemiqathango phakathi komgangatho wokugquma we-core casing core kunye nomxholo wokufuma wendlovu ekhulayo yangoku ilinganiswa ngokuchanekileyo.
