Hluav Taws Xob cov cai tswjfwm rau kev qias neeg lub cev
Qhov kev ntseeg tau thiab kev pab cuam ntawm kev ua hauj lwm ntawm kev ua hauj lwm nyob ntawm seb qhov loj ntawm cov khoom siv insulating. Cov txheej txheem yooj yim rau kev ua cov ntaub ntawv insulating muaj xws li hluav taws xob cov khoom, kev kub thiab cov khoom siv dag zog. Cov hluav taws xob cov khoom ntawm cov khoom siv insulating yog luv luv piav nyob rau hauv daim ntawv no. Hluav taws xob cov khoom ntawm cov khoom siv insulating muaj xws li ua kom muaj zog, kev tiv thaiv kev tiv thaiv, qhov dielectric qhov chaw, thiab dielectric poob.
1. Cov khoom siv hluav taws xob rhuav tshem tawm
Lub thickness ntawm lub rhuav tshem ntawm cov khoom siv rwb thaiv tsev yog faib los ntawm qhov rhuav tshem qhov hluav taws xob, qhia hauv kilovolts ib millimeter. Kev rhuav tshem ntawm cov ntaub ntawv insulating yuav tau muab faib ua 3 hom: cov kev tso tawm hluav taws xob, kev thermal tawg thiab kev tso tawm.
● Hluav taws xob ua txhaum. Nyob rau hauv qhov kev txiav txim ntawm cov hluav taws xob uas muaj zog, cov khoom siv hauv cov hluav taws xob yoojyim, thiab kev sib tsoo yog dawb, rhuav tshem cov qauv ntawm lub cev, kom qhov kev sib tawg kawg yog hu ua fais fab tuag. Qhov hluav taws xob ua kom tsis muaj zog hluav taws xob ua kom muaj linearly nrog cov thickness ntawm cov khoom. Nyob rau hauv ib qho hluav taws xob uas tsis muaj hluav taws xob, tshwj tsis yog lub impulse voltage yog luv dua 10 feeb, qhov hluav taws xob ua kom tsis muaj zog feem ntau ywj siab ntawm lub sijhawm ua hluav taws xob.
● Thermal rhuav tshem. Nyob rau hauv qhov kev txiav txim ntawm alternating fais fab, tshav kub yog generated hauv cov khoom insulating vim dielectric poob. Yog hais tias nws tsis tuaj yeem dissipated nyob rau lub sij hawm, lub ntsuas kub ntawm cov khoom yuav nce, ua qhov puas ntawm molecular qauv thiab kev ua txhaum, uas yog hu ua thermal breakdown. Lub thermal qhov hluav taws xob poob zuj zus thaum ntsuas kub ntawm qhov nruab nrab qis dua, lub thickness ntawm cov ntaub ntawv nce, lub tshav kub dissipation mob ua zuj zus, thiab lub zog muaj zog lawm. Thaum twg tus zaus nce, lub dielectric poob ntau dua thiab lub zog ua puas tsawg zog.
● Tshem tawm kev ua haujlwm. Nyob rau hauv qhov kev txiav txim ntawm lub zog muaj hluav taws xob, cov npuas muaj nyob hauv cov khoom siv thau khoom raug tso tawm los ntawm ionization; cov impurities kuj yog vaporized los ntawm cov hluav taws xob los ua cov npuas, yog li ntawd cov khoom paug tawm ntxiv lawm, uas ua rau kev puas tsuaj tag nrho cov khoom, uas yog hu ua kev tshem tawm.
Kev rhuav tshem ntawm cov ntaub ntawv insulating feem ntau yog tib yam li cov saum toj no peb cov ntaub ntawv, thiab nws yog qhov nyuaj cais lawv. Impregnating cov khoom siv insulating nrog insulating vuas los yog kua nplaum yuav ua kom cov hluav taws xob ua kom zoo dua qub thiab ua rau lub zog tawg, thiab tseem tuaj yeem txhim kho cov cua sov cua sov kom zoo dua qub rau lub zog thermal lub zog.
Yog tias koj xav yuav lub tshuab tsav kho mob, thov ua tib zoo mloog rau Cov Kab Tsom Xaj.
