Bongata ba mongobo oli ea insulation ea transformer le bona ke paramethara ea ho fumana boleng ba insulation ea transformer. Lisebelisoa tsa tlhahlobo tse bohlale tsa transformer inthaneteng li ka bokella ka bohona, tsa sekaseka litaba tsa metsi ka har'a oli le ho fumana sesosa sa ho hloleha, ho fana ka litharollo, basebelisi ba rarolla likotsi tse patiloeng tse teng ka har'a transformer ka nako, ho thibela likotsi.

1. Boemo le kotsi ea mongobo oling ea transformer

Transformer nakong ea lipalangoang, polokelo le tšebeliso e ka kenngoa ke lefats'e la kantle kapa oxidation ea oli ka boeona ho hlahisa metsi, metsi a hlahisoang a tla ba teng maemong a latelang:

E 'ngoe ke metsi a lokolohileng. Bakeng sa tlhaselo ea kantle ea metsi, joalo ka ha ho le bonolo ho e hlohlelletsa ka metsi. Ha e ame motlakase oa ho senyeha ha oli, empa hape ha e lumelle, ho bontša hore ho ka ba le metsi a qhibilihileng ka har'a oli, kalafo ea hang-hang.

Ea bobeli ke hore likaroloana tse tšesaane haholo li qhibiliha ka metsing. Hangata li tsoa moeeng li kena oling, e leng se fokotsang matla a ho senyeha ha oli ka potlako. Keketseho ea tahlehelo e mahareng, oli ea sefe ea vacuum.

Sa boraro, metsi a emulsion. Ho hlwekisa oli ho fokola, kapa ts'ebetso ea nako e telele e baka ho tsofala ha oli, kapa oli e silafalitsoe ke emulsion, e tla fokotsa tsitsipano ea sebopeho pakeng tsa oli le metsi, joalo ka oli le metsi tse kopantsoeng hammoho, li tla theha boemo ba emulsion. Kenya demulifier.

Kotsi ea eona: e 'ngoe ke ho fokotsa motlakase o senyehang oa lihlahisoa tsa oli. Motlakase o senyehang oa 100 ~ 200mg/kg o theohetse ho 1.0kV, litšila tsa faeba tse oling li monya metsi habonolo, tlas'a ts'ebetso ea tšimo ea motlakase, ho thehoa ha "borokho" bo tsamaisang motlakase pakeng tsa li-electrode, hoo ho leng bonolo ho bo qhaqha.

Ea bobeli ke ho eketsa tekanyo ea tahlehelo ea seaplane. Metsi a emulsified a emisitsoeng a na le phello e kholo ka ho fetisisa 'me ha a tšoane. Molek'hule ea faeba e sireletsang ke molek'hule ea glucose (C6H12O6). Ha metsi a kena molek'huleng ea faeba, a fokotsa ho hohela ha eona, a khothalletsa hydrolysis ea eona ho ba lintho tse tlase tsa limolek'hule, 'me a fokotsa matla a mechini le tekanyo ea polymerization ea faeba. Liteko li bontša hore 120℃, faeba ea insulation mongobong e eketseha ka makhetlo a 1, matla a mechini a faeba a fokotseha ka 1/2, ha mocheso o phahama, metsi a oli aa eketseha, metsi a faeba aa fokotseha, mocheso oa fokotseha, ho fapana le hoo. Ka hona, mongobo o ka oling o lokela ho beoa leihlo, 'me kahoo botsofali ba faeba e sireletsang mocheso bo lokela ho beoa leihlo. Ea bone ke hore metsi a khothalletsa bokhoni ba ho bola ba li-acid tsa organic 'me a potlakisa ho bola ha likarolo tsa tšepe. Ha re akaretsa, ha metsi a mangata ka oli, botsofali ba oli ka boeona bo potlaka, botsofali ba insulation ea lisebelisoa le ho bola ha likarolo tsa tšepe, kahoo ho hlokahala ho beha leihlo metsi ka oli, haholo-holo litaba tsa metsi a qhibilihileng.

2. Mokhoa oa teko bakeng sa mongobo o ka har'a oli ea ho thibela ho tjheseletsa ea transformer

Tlhahlobo ea mongobo ho thepa ea ho thibela mocheso ke ntlha ea bohlokoa ho netefatsa botšepehi le bophelo ba tšebeletso ea transformer. Mongobo o oli ea ho thibela mocheso o lula o fetoha, e leng se ka amang boleng hampe. Ho phaella moo, boholo ba mongobo bo ajoa pampiring ea ho thibela mocheso. Mongobo o ama matla a ho senyeha ha dielectric a thepa e tiileng le e thibelang mocheso ea metsi, 'me o ama sekhahla sa botsofali ba thepa ea ho thibela mocheso ea cellulose le tšekamelo ea ho thehoa ha lipululana nakong ea ho jara boima ba 'mele.

Mocheso o sebakeng se itseng, mojaro, botsofali, ho dutla ha metsi le mabaka a mang a ka baka diphetoho tse sa kgaotseng mongobong. Ka hona, ho hlokahala tlhokomelo e tswelang pele le tlhahlobo ka phetoho ya potoloho ya mocheso wa transformer. Sena se hlokahala haholoholo bakeng sa di-transformer tse imetsweng haholo kapa tse fihlang sehlohlolong. Mongobo o felletseng tsamaisong ya ho kwahela di-transformer o laolwa ke mongobo wa cellulose le mokelikeli. Kamano ya mongobo pakeng tsa pampiri e kwahelang le oli e kwahelang e itshetlehile feela ka mocheso. Ha mocheso o ntse o eketseha, ho qhibiliha ha metsi ka hara oli e kwahelang (bokgoni ba ho tshwara metsi ba tharollo) ho a eketseha, mme metsi a tla fetisetswa ho tloha pampiring e kwahelang ho ya oling e kwahelang.

Ha mocheso o theoha, ts'ebetso e fetoha ka tsela e fapaneng, empa phallo ea metsi ho tloha mokelikeling o metsi ho ea ho thepa e tiileng e sireletsang mocheso e lieha haholo. Ka hona, metsi a oli e sireletsang mocheso nakong ea ho pholisa a phahame ho feta nakong ea ho futhumatsa. Ka hona, e le ho utloisisa ka nepo kabo ea mongobo ka har'a transformer, ho hlokahala ho tseba boemo ba lisebelisoa potolohong ea tsona ea mocheso. Ho utloisisa mongobo oa 'nete oa pampiri e sireletsang mocheso ka ho beha leihlo mongobo ka har'a mokelikeli o metsi, transformer e tlameha ho ba boemong bo tsitsitseng ba mocheso.

Ho tlala ha metsi ka oli e sireletsang mocheso ho hloka ho lekanngoa hobane mongobo o ka oli e sireletsang mocheso o amana haufi-ufi le liphetoho tsa mocheso 'me ho na le mocheso o itseng ka lebokoseng le ka sehloohong la transformer (hangata karolo e ka holimo ea lebokose e futhumetse ho feta e ka tlase). Ho phethela ho tlala maemo, tlhahlobo ea sistimi ea litsebi e fumana peresente ea ho tlala ha metsi ka tlase. Sena se ka fumanoa ka ho sebelisa mocheso o tlalehiloeng ke sensor le sebaka sa eona sa ho nka sampole.

Tlhahlobo e nka hore mocheso o ka hodimo wa transformer o phahame ka 10℃ ho feta mocheso o ka tlase. Haeba sebaka se seng ntle le ka hodimo kapa tlase se sebediswa e le ntlha ya ho nka sampole, ho kheloha ha mocheso ho tlameha ho hlaloswa. Ka ho tlala ha mongobo le mocheso o itseng o lekantsweng, sistimi ya ditsebi e tla ba peresente e itseng ya tlala e lekantsweng bakeng sa diphetho tsa ho bala mongobo wa pampiri ya insulation. Ho bohlokwa ho hlokomela hore palo ena e itshetlehile tlhahisoleseding e tswang tekanyong e le nngwe mme e kanna ya se bontshe mongobo wa nnete wa pampiri ya insulation, haholoholo kamora hore transformer e fete phetoho e kgolo ya mocheso.

Haeba sistimi ea litsebi e fumana hore transformer e leka-lekaneng (pampiri e thibelang mocheso ha e lokolle kapa hona ho monya mongobo), peresente ea bobeli ea ho tlala ho lekanyelitsoeng ea baloa, e leng karolelano ea litekanyo tse 30 tsa ho qetela tsa peresente ea ho tlala ha transformer e leka-lekaneng. Mocheso le phapang tse tlalehiloeng kaholimo li khetholla litekanyetso tsa ho fumana boteng kapa ho se be teng ha tekano.

Re na le mefuta ea lisebelisoa tsa liteko bakeng sa teko ea oli ea Transformer, joalo ka: Interfacial Tension Tester, Oil Particle Counter tester, Pour point test jj. Potso efe kapa efe, ka kopo ikopanye le rona ka bolokolohi.
