13KN PW-33-Y High Voltage Pin Uhlobo lwe-Porcelain Insulator

Incazelo Yomkhiqizo

Isivikeli sephinikhodi siyingxenye esetshenziselwa ukusekela noma ukumisa intambo kanye nokwenza okokufaka ugesi phakathi kombhoshongo nocingo [1].Uhlobo lwephinikhodi izingxenye zobumba ezivamile ze-ceramic insulator kanye nensimbi ecijile zinamathiselwe ndawonye nge-adhesive kasimende, futhi ingaphezulu lezingxenye ze-porcelain limbozwe ungqimba olucwebezelayo ukuze kuthuthukiswe ukusebenza kokufakwa kwe-insulator.
Ama-insulators azoba namandla anele okufakwa ngaphakathi kanye namandla okusebenza.Ngesikhathi sokusebenza, ama-insulators ngeke amelane kuphela nesenzo se-voltage yokusebenza kanye ne-voltage engaphezulu, kodwa futhi abe nokumelana okwanele ekugugulekeni kokungcola kwamakhemikhali, futhi angakwazi ukuzivumelanisa nomthelela wokushintsha kwezinga lokushisa nendawo ezungezile.

Ukusebenza komkhiqizo

Izakhiwo eziyisisekelo zama-pin insulators zihlanganisa izakhiwo zikagesi, zemishini nezokushisa.Ngaphezu kwalokho, kukhona ukumelana kwemvelo nokumelana nokuguga nezinye izakhiwo.

(1) Ukusebenza kukagesi: Ukukhishwa okulimazayo endaweni evikelayo kubizwa ngokuthi i-flashover, futhi isici se-flashover siwukusebenza okuyinhloko kagesi kwezivikeli.Emazingeni ahlukene kagesi, ama-insulators anezidingo ezihlukene zokubekezelela i-voltage, okuhlanganisa ukubekezelelwa kwamandla kagesi omile kanye nokumanzi, ukubekezelela amandla kagesi okuthinta umbani, ukubekezelela igagasi lokunqanyulwa kombani, kanye nokubekezelela amandla kagesi.Ukuze ugweme ukuphuka ngesikhathi sokusebenza, i-voltage yokuwohloka ye-insulator iphakeme kune-flashover voltage.Esivivinyweni sasefekthri, isivikeli se-porcelain sohlobo lokuwohloka ngokuvamile sidlula ekuhlolweni kwenhlansi, okungukuthi, amandla kagesi aphezulu ayanda ukuze enze izinhlansi ezivamile zenzeke endaweni yokushisa, futhi silondoloze isikhathi esithile ukuze sibone ukuthi iphukile yini.Amanye ama-insulators adinga ukuhlolwa kwe-corona, ukuhlolwa kokuphazanyiswa komsakazo, ukuhlolwa kokukhipha ingxenye kanye nokuhlolwa kokulahlekelwa kwe-dielectric.Amandla kagesi wama-insulators ezindaweni eziphakeme ayancipha ngenxa yokuncipha kokuminyana komoya, ngakho-ke i-voltage yawo yokumelana kufanele inyuswe lapho iguqulelwa ezimweni ezijwayelekile zomkhathi.I-voltage ye-flashover yama-insulators angcolile lapho ithinteka ngomswakama iphansi kakhulu kune-voltage yabo eyomile nemanzi ye-flashover.Ngakho-ke, ukwahlukanisa kufanele kuqiniswe noma izivikeli ezimelana nokungcola kufanele zisetshenziswe ezindaweni ezingcolile, futhi ibanga le-creepage (isilinganiso sebanga le-creepage kuya ku-voltage elinganisiwe) kufanele libe phezulu kunaleso lama-insulators avamile.Uma kuqhathaniswa nama-insulators e-AC, ama-insulators e-DC anokusabalalisa okungalungile kwensimu kagesi, i-adsorption yezinhlayiya zokungcola kanye ne-electrolysis, i-flashover voltage ephansi, futhi ngokuvamile idinga umklamo okhethekile wesakhiwo kanye nebanga elikhudlwana le-creepage.
