I-oyile efunyenweyo engacocwanga ibizwa ngokuba yi-oyile engaphantsi, equlethe amanzi amaninzi kunye nokungcola, kwaye amandla ayo e-dielectric angaphantsi kwe-12KV.Ngokukodwa kwi-oyile ephantsi kunye namanzi amaninzi, abanye abasebenzisi basebenzisa i-high-dielectric power tester ukuyivavanya ukuze bazi ukuba kubi kangakanani.Ngenxa yoko, inkqubo yovavanyo lwe-high-voltage yovavanyo lwamandla e-dielectric kwi-oyile ekhuselayo yonakaliswa lula.
Ngokuqhelekileyo, isithuba phakathi kwee-electrode zombane ophezulu sizaliswe ngeoli yokugquma.Ngexesha lovavanyo, i-voltage phakathi kwee-electrode ezimbini iyaqhubeka nokunyuka, kwaye i-oyile yeendaba ezinamandla ahlukeneyo okugquma angakwazi ukumelana nombane ophakamileyo we-voltage wamaxabiso ahlukeneyo.Oku kunyuka kwebala lombane lombane kubangela ukuba i-oyile ye-insulating media iphulwe ngokukhawuleza xa ingakwazi ukumelana nayo.Umbane omkhulu uqokelelwa sisixhobo kwaye ngokukhawuleza uvale kwaye ulahlekelwe yi-voltage ephezulu kwaye ujike kwi-step-down operation.

Xa uvavanya i-oyile ekumgangatho ophantsi kunye nomxholo wamanzi anzima, i-voltage phakathi kwee-electrode ze-hemispheres ezimbini iyaqhubeka nokunyuka, kwaye kwangaxeshanye, amasuntswana amanzi kumbindi we-oyile afunxwa kumsantsa ophakathi kweebhola phantsi kwesenzo sombane. intsimi yombane ene-high-voltage ukwenza ikholamu yamanzi efana nenkungu emhlophe.Ukuqina, ukuxhathisa kwamanzi kuya kuncinci kwaye kuncinci.Olu hlobo lwenkqubo edlulayo apho ukuxhathisa kwamanzi kuba kuncinci kwaye ikhoyo ngoku ye-high-voltage transformer inyuka (ngaphandle kokuphuka kunye nokukhutshwa ngokukhawuleza) kuya kubangela umonakalo kwisixhobo, isichasi somda sangoku, i-fuse iya kutshisa, kwaye i-high-voltage transformer yesixhobo iya kutshiswa.
Uvavanyo loxinzelelo oluphantsi lweoyile
Olu hlobo lwe-oyile ephakathi ludla ngokuba yi-15 ~ 35KV.Nangona i-oyile medium iqulethe inani elincinci lamanzi kunye nokungcola, isixhobo sisenokuvavanya ngokuqhelekileyo.Ibonisa kuphela ukuba amasuntswana amaqamza (okanye ukungcola) adsorbed kwisithuba phakathi kweebhola ukuvelisa ukukhutshwa ngexesha lokunyusa.Iibhubhu zomoya ziphulwa kwaye zikhutshwe kwi-gap phakathi kweebhola, kwaye ioli iyazaliswa, ngoko ke uxinzelelo luqhubeka lukhula kude kube yindawo ephezulu yokuthwala i-oil medium.Olu hlobo lwedatha yovavanyo lusathembekile.
Uvavanyo lweoli ephantsi
Xa ukubuyisela i-oil medium ukuba ihluzwe, njengamaconsi amanzi okanye ukungcola okunokubonwa ngeso lenyama, kungcono ukuba ungasebenzisi ngenkani izixhobo zokuvavanya.Kumgangatho we-oyile okumgangatho ophantsi ogcinwe ngaphezu kweeyure ezingama-24, amathontsi amanzi amakhulu atshona ukuya emazantsi e-oyile, kwaye amaqamza acolekileyo adada phezu kweoli.Umsebenzisi kufuneka asebenzise izixhobo ezingangcoliswanga ngamanzi ukukhupha isampuli yeoli kwindawo ephakathi.Ngethuba lovavanyo, qaphela ngokusondeleyo ukuba kukho ikholamu yenkungu efana nomtya omncinci njengoko kuboniswe kuMzobo we-9 xa uxinzelelo lwenyuka (ukuqala kwixesha lokuqala lokunyuka kwengcinezelo).Cima amandla ngoko nangoko ukumisa uvavanyo.Okanye ukuba kukho amanqaku amaninzi okukhutshwa okuqhubekayo ngexesha lokunyusa, isixhobo asikwazi ukuvala ngokuzenzekelayo, kwaye umsebenzisi kufuneka acime ngokukhawuleza ukunikezelwa kwamandla kwaye ayeke uvavanyo.
Ucalucalulo lweziphumo zovavanyo
Kuvavanyo, i-spark discharge voltage iyatshintsha kwiimeko ezine:
(1) Umbane wesibini wokukhupha intlantsi uphantsi kakhulu.Ixabiso lolu vavanyo linokuba liphantsi ngenxa yempembelelo yezinye izinto zangaphandle ezilethwe yisampuli yeoli kwikomityi yeoli okanye indawo engcolileyo ye-electrode yekomityi yeoli ngaphambi kokuzaliswa kweoli.Ngeli xesha, ixabiso eliqhelekileyo lamaxesha angama-2-6 lingathathwa.
(2) Ixabiso lamandla ombane leentlantsi ezintandathu ezikhutshwayo liyenyuka kancinci kancinci, kwaye lenzeka ngokubanzi kwiisampulu zeoyile ezingakhange zicocwe okanye zinyangwe ngokucokisekileyo kwaye zifunxe ukufuma.Oku kungenxa yokuba inqanaba lokufuma kwe-oyile liyaphuculwa emva kokuba i-oyile ikhutshiwe.
(3) Amaxabiso ombane wentlantsi ezintandathu ezikhutshwa ngokuthe ngcembe.Ngokuqhelekileyo, kubonakala kwioli ecocekileyo yovavanyo, kuba iinqununu ezihlawulelwayo zamahhala, amaqamza omoya kunye neetshiphu zekhabhoni zonyuka ngokulandelelana, nto leyo eyonakalisa ukusebenza kweoyile.Ukongezelela, abanye abavavanyi be-oyile abazenzekelayo abashukumisi ngexesha leemvavanyo ezi-6 ezilandelelanayo, kunye ne-electrodes phakathi kwe-electrode I-carbon particles yanda ngokuthe ngcembe, okubangela ukuhla kancinci kwi-spark discharge voltage.
(4) Ixabiso lamandla ombane wokukhupha intlantsi liphantsi kuzo zombini iziphelo kwaye liphezulu embindini.Oku kuqhelekile.
Ukuba kukho ukusabalalisa okukhulu kwexabiso le-voltage yokumelana, umzekelo: kwiimvavanyo ezi-6 eziqhutywe ngokwendlela yokuthintela, ixabiso lexesha elinye liyaphambuka kwamanye amaxabiso ngesixa esikhulu, ixabiso leli xesha alinakubalwa. , okanye uvavanyo lwesampulu yeoli luya kuthathwa kwakhona.Inokwenzeka ukuba ibangelwa ngumgangatho ophantsi we-oyile okanye ukuhanjiswa okungalinganiyo kwekhabhoni yasimahla.
Ngenxa yokusasazwa okukhulu kweoyile yokumelana neziphumo zovavanyo lombane, ukuba i-voltage yokuqhekeka iphezulu kakhulu (kufuphi ne-80KV) okanye iziphumo ziyafana ngalo lonke ixesha, oko kuthetha ukuba isixhobo singonakala, nceda uqhagamshelane nomenzi.
