13KN PW-33-Y High Voltage Pin Hom Porcelain Insulator
Khoom txhais
Ib tus pin insulator yog ib qho khoom siv los txhawb lossis tshem tawm cov xaim thiab tsim cov hluav taws xob rwb thaiv tsev ntawm tus pej thuam thiab cov hlau [1].Pin hom feem ntau ceramic insulator porcelain qhov chaw thiab cam khwb cia hlau yog glued ua ke nrog cov cement nplaum, thiab qhov chaw ntawm cov plooj (porcelain) yog coated nrog ib txheej ntawm glaze los txhim kho cov rwb thaiv tsev kev ua tau zoo ntawm cov insulator.
Insulators yuav tsum muaj lub zog rwb thaiv tsev txaus thiab txhua yam muaj zog.Thaum lub sijhawm ua haujlwm, cov insulators yuav tsum tsis tsuas yog tiv taus qhov kev ua haujlwm ntawm qhov hluav taws xob thiab dhau qhov hluav taws xob, tab sis kuj tseem muaj kev tiv thaiv txaus rau kev yaig ntawm cov tshuaj tsis huv, thiab tuaj yeem hloov mus rau qhov kub hloov pauv thiab ib puag ncig ib puag ncig.
Khoom ua haujlwm
Cov yam ntxwv ntawm tus pin insulators muaj xws li hluav taws xob, mechanical thiab thermal zog.Tsis tas li ntawd, muaj kev tiv thaiv ib puag ncig thiab kev laus tiv thaiv thiab lwm yam khoom.
(1) Kev ua haujlwm hluav taws xob: Kev puas tsuaj tawm ntawm qhov chaw insulating yog hu ua flashover, thiab cov yam ntxwv flashover yog lub ntsiab hluav taws xob ua haujlwm ntawm insulators.Rau ntau theem voltage, insulators muaj qhov sib txawv voltage kam rau ua, nrog rau lub hwj chim zaus qhuav thiab ntub voltage kam rau ua, xob laim cuam tshuam voltage kam, xob laim cuam tshuam yoj txiav tawm voltage kam rau ua, thiab kev ua haujlwm cuam tshuam voltage kam rau ua.Txhawm rau kom tsis txhob tawg thaum lub sijhawm ua haujlwm, qhov hluav taws xob tawg ntawm ib qho hluav taws xob yog siab tshaj qhov hluav taws xob flashover.Nyob rau hauv lub Hoobkas kuaj, lub breakdown hom porcelain insulator feem ntau mus los ntawm lub txim hluav taws xob kuaj, uas yog, high voltage yog nce kom nquag sparks tshwm sim nyob rau hauv lub rwb thaiv tsev nto, thiab tswj rau ib tug tej lub sij hawm los saib seb nws puas puas.Qee cov insulators yuav tsum tau kuaj corona, kuaj xov tooj cua cuam tshuam, kuaj ib nrab tawm thiab kuaj dielectric poob.Lub zog hluav taws xob ntawm cov insulators nyob rau hauv qhov chaw siab siab txo qis vim qhov txo qis hauv huab cua, yog li lawv cov hluav taws xob tiv taus yuav tsum tau nce ntxiv thaum hloov mus rau cov qauv atmospheric.Lub flashover voltage ntawm cov pa phem insulators thaum lawv cuam tshuam nrog noo noo ntau dua li lawv qhov qhuav thiab ntub flashover voltage.Yog li ntawd, rwb thaiv tsev yuav tsum tau ntxiv dag zog los yog muaj kuab paug resistant insulators yuav tsum tau siv nyob rau hauv tej qhov chaw muaj kuab paug, thiab lub creepage nrug (qhov piv ntawm creepage nrug rau rated voltage) yuav tsum siab tshaj li ib txwm insulators.Piv nrog AC insulators, DC insulators muaj cov khoom siv hluav taws xob tsis zoo, adsorption ntawm cov pa phem thiab electrolysis, tsis tshua muaj hluav taws xob flashover, thiab feem ntau xav tau cov qauv tsim tshwj xeeb thiab loj dua creepage nrug.
