Indawo kawoyela etholiwe engahlungiwe ibizwa ngokuthi i-inferior oil, equkethe amanzi amaningi nokungcola, futhi amandla ayo e-dielectric angaphansi kuka-12KV.Ikakhulukazi kuwoyela wekhwalithi ephansi onamanzi amaningi, abanye abasebenzisi basebenzisa i-high-dielectric energy tester ukuze bayihlole ukuze bazi ukuthi kubi kangakanani.Ngenxa yalokho, uhlelo lokuhlola lwe-high-voltage lokuhlola amandla e-dielectric lwamafutha okuvikela lulimala kalula.
Imvamisa, isikhala phakathi kwama-electrode aphezulu kagesi sigcwaliswa ngamafutha avikelayo.Ngesikhathi sokuhlolwa, i-voltage phakathi kwama-electrode amabili iyaqhubeka nokukhula, futhi imidiya kawoyela enamandla ahlukene e-insulation ingamelana nezindawo zikagesi ezine-voltage ephezulu zamanani ahlukene.Le nkambu kagesi enamandla amakhulu akhuphukayo ibangela ukuthi isisetshenziswa sikawoyela esivikelayo siphuke kungazelelwe lapho singakwazi ukumelana nawo.I-current enkulu iqoqwa ithuluzi futhi ivale ngokushesha futhi ilahlekelwe amandla kagesi aphezulu bese iphendukela ekusebenzeni kokuya phansi.
I-GD6100D Insulation oil Tan Delta Tester
Lapho kuhlolwa uwoyela wekhwalithi embi enamanzi asindayo, i-voltage phakathi kwama-electrode ama-hemispheres amabili iyaqhubeka nokukhuphuka, futhi ngasikhathi sinye, izinhlayiya zamanzi endaweni kawoyela zingena phakathi kwegebe eliphakathi kwamabhola ngaphansi kwesenzo se-a. inkambu kagesi ene-voltage ephezulu ukwenza ikholomu yamanzi efana nenkungu ephaphathekile.Kujiyile, ukumelana namanzi kuya ngokuya kuncipha.Lolu hlobo lwenqubo yesikhashana lapho ukumelana kwamanzi kuba kuncane futhi amandla amanje e-high-voltage transformer anda (ngaphandle kokuwohloka nokuphuma kungazelelwe) kuzodala umonakalo ensimbini, i-standing resistor yamanje, i-fuse izosha, ngisho i-high-voltage transformer yensimbi izoshiswa.
Ukuhlolwa kwe-low pressure oil medium
Lolu hlobo lwamafutha luvamise ukuba ngu-15 ~ 35KV.Ngisho noma indawo kawoyela iqukethe inani elincane lamanzi nokungcola, ithuluzi lisengakwazi ukuhlola ngokujwayelekile.Kubonisa kuphela ukuthi ezinye izinhlayiya zebhamuza (noma ukungcola) zikhangiswa esikhaleni esiphakathi kwamabhola ukuze kukhiqizwe ukukhishwa ngesikhathi senqubo yokuthuthukisa.Ama-bubbles omoya aphukile futhi akhishwe egebeni eliphakathi kwamabhola, futhi amafutha agcwaliswa, ngakho-ke ukucindezela kuyaqhubeka kwanda kuze kube yilapho iphuzu eliphezulu lokuthwala le-oil medium liphulwa.Lolu hlobo lwedatha yokuhlola lusathembekile.
Ukuhlolwa kwamafutha aphansi
Lapho ubuyisela i-oyili okufanele ihlungwe, njengamaconsi amanzi noma ukungcola okungabonwa ngeso lenyama, kungcono ukungasebenzisi ngenkani izinsimbi zokuhlola.Endlini kawoyela esezingeni eliphansi egcinwe amahora angaphezu kuka-24, amaconsi amanzi amakhulu ashona phansi kuwoyela, futhi amagwebu ezinhlayiyana ezincane antanta phezulu kuwoyela.Umsebenzisi udinga ukusebenzisa izitsha ezingangcolisiwe ngamanzi ukuze akhiphe isampula likawoyela engxenyeni emaphakathi.Ngesikhathi sokuhlolwa, bhekisisa ukuthi ikhona yini ikholomu yenkungu efana nentambo encane njengoba kuboniswe kuMfanekiso 9 lapho ukucindezela kunyuswa (kusukela esikhathini sokuqala sokunyuka kwengcindezi).Vala amandla ngokushesha ukuze umise ukuhlola.Noma uma kunamaphoyinti amaningi okukhishwa okuqhubekayo phakathi nenqubo yokuthuthukisa, ithuluzi alikwazi ukuvala shaqa ngokuzenzakalelayo, futhi umsebenzisi kufanele avale ngokushesha ukunikezwa kwamandla futhi amise ukuhlola.
Ukucwaswa kwemiphumela yokuhlolwa
Esivivinyweni, i-spark discharge voltage iyashintsha ezimweni ezine:
(1) I-voltage yesibili yokukhipha inhlansi iphansi kakhulu.Inani lalokhu kuhlolwa lingase libe phansi ngenxa yethonya lezinye izici zangaphandle ezilethwe isampula yamafutha enkomishini yamafutha noma indawo engcolile ye-electrode yenkomishi kawoyela ngaphambi kokugcwalisa uwoyela.Ngalesi sikhathi, inani elijwayelekile lezikhathi ezingama-2-6 lingathathwa.
(2) Inani lamandla kagesi lokuphuma kwezinhlansi eziyisithupha likhuphuka kancane kancane, futhi ngokuvamile livela kumasampula kawoyela angazange ahlanzwe noma aphathwe kahle futhi amunce umswakama.Lokhu kungenxa yokuthi izinga lomswakama kawoyela liyathuthukiswa ngemva kokuba uwoyela usuphumile.
(3) Amanani kagesi ezinhlansi eziyisithupha aphuma kancane kancane.Ngokuvamile, kubonakala emafutheni ahlanzekile okuhlolwa, ngoba izinhlayiya ezikhokhiswa mahhala ezikhiqizwe, amabhamuza omoya nama-carbon chips akhula ngokulandelana, okulimaza ukusebenza kokufakwa kwamafutha.Ukwengeza, abanye abahloli bamafutha okuzenzakalelayo abanyakazi phakathi nokuhlolwa oku-6 okulandelanayo, futhi ama-electrode phakathi kwama-electrode Izinhlayiya ze-carbon zikhula kancane kancane, okuholela ekwehleni kancane kancane kwe-voltage yokukhipha inhlansi.
(4) Inani lamandla kagesi okukhipha inhlansi liphansi kuzo zombili iziphetho futhi liphakeme phakathi nendawo.Lokhu kuvamile.
Uma kukhona ukuhlakazeka okukhulu kwevelu ye-standard voltage, isibonelo: ekuhlolweni okungu-6 okwenziwe ngokwendlela yokuhlola yokuvimbela, inani lesikhathi esisodwa liphambuka kwamanye amanani ngenani elikhulu, inani lalesi sikhathi angeke libalwe. , noma ukuhlolwa kwesampula kawoyela kuzothathwa futhi.Kungenzeka ukuthi kubangelwa izinga eliphansi likawoyela noma ukusatshalaliswa okungalingani kwekhabhoni yamahhala.
Ngenxa yokuhlakazeka okukhulu kwamafutha amelana nemiphumela yokuhlolwa kwe-voltage, uma i-voltage yokuwohloka iphezulu kakhulu (eseduze no-80KV) noma imiphumela iyafana ngaso sonke isikhathi, kusho ukuthi ithuluzi lingase lonakale, sicela uxhumane nomkhiqizi.
