Imishini kagesi ephezulu ye-voltage kumele ilondoloze ukufakwa okuhle ngesikhathi sokusebenza, ngakho-ke uchungechunge lokuhlolwa kokufakwa kufanele kwenziwe kusukela ekuqaleni kokukhiqizwa kwemishini. Lezi zivivinyo zifaka phakathi: Ukuhlolwa kwezinto okubonakalayo kwinqubo yokukhiqiza, ukuhlolwa okuphakathi kwenqubo yokukhiqiza, ukuhlolwa okusebenzayo komkhiqizo, ukuqeqeshwa kwefekthri, ukusetshenziswa kwezivivinyo zokuvikelwa kwesayithi, nokusebenza ngesikhathi sokuvikela. Ubufakazi bemishini kagesi kanye nokuhlolwa kokuvimbela izivivinyo ezimbili ezibaluleke kakhulu. I-People's Republic of China Power Power Power Power Power China neKhodi Yezwe: DL / T 596-1996 "Izinqubo Zokuhlola Ukuvimbela Amathuluzi" Nciphisa Ukuhlolwa Kwamathuluzi Ngakunye.
2. Ukufakwa kokuvimbela ukuhlolwa
Ukuhlolwa kokuvimbela kokuvimbela imishini kagesi kuyisinyathelo esibalulekile sokuqinisekisa ukusebenza okuphephile kwemishini. Ngemuva kokuhlolwa, isimo sokufakwa kwemishini singathathwa, ingozi ekufakweni ingatholakala ngesikhathi, futhi ukuvikelwa kungasuswa. Uma kunenkinga enkulu, kuyadingeka ukufaka esikhundleni semishini ukugwema ukulahleka okungenakulinganiswa, njengokukhishwa kwamandla noma ukulimala kwemishini okubangelwa ukwehluleka kokufakwa ngesikhathi sokusebenza.
Ukuhlolwa kokuvinjelwa kokuvimbela kungahlukaniswa izigaba ezimbili: Ukuhlolwa okungeyona okulimazayo noma ukufakwa kwesici sokufakelwa, okusho amapharamitha ahlukahlukene alingiswa alinganiswe kumandla kagesi aphansi noma ngezindlela ezingeke zilimaze ukufakwa, okubandakanya nokulinganiswa kwamanje, ukuvuza kwamanje, Ukulahleka kwe-dielectric tangent, njll. Bese ubona ukuthi ukufakwa kunamaphutha. Ukuhlolwa kukhombisile ukuthi le ndlela ilusizo, kepha ayikwazi ukusetshenziselwa ukucacisa ngokuthembekile ukuthola amandla kagesi wokufakelwa. Elinye livivinyo lokubhubhisa noma ukuhlolwa kwengcindezi. I-voltage esetshenziswe esivivinyweni iphakeme kune-voltage esebenzayo yemishini, futhi izidingo zokuhlolwa kokufakelwa ziqinile kakhulu. Ikakhulu, kunengozi enkulu yokudalula nokubutha ukushiyeka, futhi uqinisekise ukuthi ukufakwa kunamandla athile kagesi, kufaka phakathi amandla e-DC amelana nawo, njll. Ububi bokuvulwa kwe-vortantle voltage ukuthi kuzodala abanye Ukulimala kokufakelwa.
I-3
Ukuze uhlangabezane nezidingo zocwaningo lokufaka onjiniyela kagesi kanye nokuhlolwa kwezinsizakusebenza zogesi, futhi ugqugquzele ukukhushulwa kanye nokusetshenziswa kobuchwepheshe obusha bokuhlolwa kwezinsizakusebenza ze-Electrical Service, i-GB Preplamement Replingment "ngokuqondile Ukucaciswa kokuhlolwa okuhlukahlukene. Ngaphezu kokunye ukuhlola okuvimbela ukuvimba, izivivinyo zokubuyiselwa kogesi zihlanganisa nezinye izivivinyo zesimo, njengokumelana kwe-Transformer DC kanye nokuhlolwa kwezilinganiso, izivivinyo zokumelana nokujikeleza kwesifunda, njll.
4. Isisekelo esiyisisekelo sokuhlolwa kokuvimbela ukuvimba
I-4.1 Ukuhlolwa kokulwa kokumelana nokungamelana nokuvuselelwa kokufakwa kwe-insulation kuyinto esetshenziswa kakhulu futhi elula kunazo zonke ekuhlolweni kokufakwa kwemishini kagesi. Inani lokumelana nokufakelwa kokufakelwa lingakhombisa ngempumelelo ukushiyeka kokufakelwa, njengokunomswakama ophelele, ukungcoliswa komhlaba, ukushisa ngokweqile nokuguga. Ithuluzi elisetshenziswa kakhulu lokuhlola ukumelana kokufakelwa kokufakwa kokufakelwa kokungahambisani (umhloli wokumelana wokufakelwa).
Abahloli bokumelana nokungena ngaphakathi (abahloli bokumelana bodwa) bavame ukuba nezinhlobo ezinjengama-volts ayi-100, amavoloshi angama-250, ama-volts angama-100, ama-volts angama-2500, nama-5000 volts. Umhloli wokumelana wokufakelwa kufanele asetshenziswe ngokuya ngezinqubo zokuhlola zokuvimbela izivivinyo zamandla kagesi ".
4.2 Ukuhlolwa kwamanje
I-voltage ye-General DC yokumelana nokungamelana ne-DC yokuvimbela ukumelana iphansi kune-2.5KV, ephansi kakhulu kune-voltage esebenzayo yemishini ethile kagesi. Uma ucabanga ukuthi i-voltage yokulinganisa yomhloli wokumelana wokufakelwa iphansi kakhulu, ungalinganisa inani elivuzayo lemishini kagesi ngokungeza i-voltage ephezulu ye-DC. Imishini esetshenziswayo esetshenziswayo yokulinganisa yamanje yamanje ifaka ama-transformers aphezulu wokuhlola ama-voltage kanye ne-DC ephezulu-volage generator. Lapho imishini inamaphutha, ukuvuza kwamanje ngaphansi kwamandla kagesi aphezulu kukhulu kakhulu kunalokho ngaphansi kwamandla kagesi aphansi, okungukuthi, ukumelana kokufakelwa ngaphansi kwamandla kagesi aphezulu kuncane kunalokho ngaphansi kwamandla aphansi.
Akekho nomehluko omkhulu phakathi kokulwa nokuvuza kwamanje nokungathathiswa kwezokwelapha zokumelana nezokwelapha
(1) I-test voltage iphakeme kakhulu kunaleyo preser yokulwa nokufakelwa. Ukushiyeka kokufakwa ngokwayo kudalulwa kalula, futhi ukushiyeka okuthile kokuguqulwa ngaphandle kokungena kungatholakala.
(2) Ukukala ukuxhumana phakathi kokuvuza kwamanje kanye ne-voltage esetshenzisiwe kusiza ukuhlaziya izinhlobo zeziphene zokufakelwa.
.
I-4.3 DC imelana nokuhlolwa kwe-voltage
I-DC emelana nokuhlolwa kwe-voltage iphakeme
Ukuxhumana Ndlukwane Ukuhlolwa Kwe-voltage kwesinye isikhathi kwenza ubuthakathaka obuthile ekufakweni okuvelele kakhulu. Ngakho-ke, kuyadingeka ukwenza izivivinyo ekumelaneni kokufakelwa, isilinganiso sokutholwa, ukuvuza kwamanje nokulahleka kwe-dielectric ngaphambi kokuhlolwa. Uma umphumela wokuhlola uyanelisa, ukuxhumana kwezokuxhumana kuhambisana nokuhlolwa kwe-voltage kungenziwa. Ngaphandle kwalokho, kufanele kubhekwane nakho ngokuhamba kwesikhathi, futhi ukuxhumana kubhekiswa kuhlolo lwe-voltage kufanele kwenziwe ngemuva kokuthi ithagethi ngalinye likufanelekile ukugwema ukulimala okungadingekile kokufakelwa.
4.5 Ukuhlolwa kwe-dielectric ukulahleka factor gegδ
I-Dielectric Loss Factor TGΔ ingenye yezinhloso eziyisisekelo ezibonisa ukusebenza kwezithako. I-dielectric ukulahleka factor i-TGΔ ikhombisa ipharamitha yesimo sokuncipha kokufakelwa. Kungakuthola ngenkuthalo ukufakwa okuphelele kwemishini kagesi ethintekile ngokumanzisa, ukonakala kanye nokuwohloka, kanye nokulimala kwasendaweni kwemishini emincane.
Ukuqhathanisa i-MedicalNantle Stratetand Voltage Tesser ukuze imelana nokuvuselelwa kwamanje nokuvuza izivivinyo zamanje, i-dielectric Loss Factor TGδ inezinzuzo ezinkulu. Akuhlangene ngalutho ngogesi wokuhlola, usayizi wesampula wokuhlola nezinye izinto, futhi kulula ukwahlukanisa ukushintshwa kwemishini kagesi. Ngakho-ke, i-Dielectric Loss Factor TGΔ ingesinye sezivivinyo eziyisisekelo zokuhlolwa kokufakwa kwezinto ezisebenza ngokusebenza kwamandla kagesi.
I-Dielectric Loss Factor TGΔ ingaba wusizo ukuthola amaphutha alandelayo wokufakelwa:
(1) umswakama; (2) ngena esiteshini esisebenzayo; (3) Ukufakelwa kuqukethe ama-bubble endiza mahhala, kanye nokufakwa kwamaqembu namagobolondo; (4) Ukufakelwa kungcolile, kukhuza, kanye nokuguga.
