Ib rab koob Insulator yog hom hlau siv los txhawb lossis tshem tawm cov xov hlau

Ib tus pin insulator yog ib qho khoom siv los txhawb lossis tshem tawm tus neeg xyuas pib thiab tsim hluav taws xob rwb thaiv tsev ntawm tus pej thuam thiab tus neeg xyuas pib. Cov plooj (porcelain) thiab cam khwb cia hlau ntawm rab koob hom ceramic insulator yog glued ua ke nrog cov cement nplaum, thiab qhov saum npoo ntawm cov plooj (porcelain piece) yog coated nrog ib txheej ntawm glaze los txhim kho kev ua haujlwm ntawm cov rwb thaiv tsev.

Insulators yuav tsum muaj lub zog dielectric txaus thiab lub zog txhua yam, tsis yog tsuas yog tiv taus qhov cuam tshuam ntawm kev ua haujlwm voltage thiab overvoltage thaum lub sijhawm ua haujlwm, tab sis kuj yuav tsum muaj kev tiv thaiv txaus rau kev yaig ntawm cov tshuaj impurities, thiab hloov mus rau kev hloov pauv ntawm qhov kub thiab txias ntawm ib puag ncig. ib puag ncig.

Cov plooj (porcelain) thiab cam khwb cia hlau ntawm rab koob hom ceramic insulator yog glued ua ke nrog cov cement nplaum, thiab qhov saum npoo ntawm cov plooj (porcelain piece) yog coated nrog ib txheej ntawm glaze los txhim kho kev ua haujlwm ntawm cov rwb thaiv tsev. Siv cov khoom pov thawj noo noo rau saum npoo ntawm cov kua nplaum uas cov cam khwb cia hlau thiab cov plooj (porcelain) yog glued.

Qhov laj thawj tseem ceeb vim li cas cov kab hluav taws xob muaj feem cuam tshuam rau xob laim thiab cov pa phem flashovers yog vim li cas tus pin insulators ntawm cov kab muaj kab mob thiab nqus dej noo nyob rau hauv cov hnub los nag, thiab cov txheej txheem rwb thaiv tsev raug txo, uas ua rau cov kab tsis ua hauj lwm los ntawm cov pa phem flashovers thiab breakdowns.

Tom qab tawg los yog raug mob hnyav, tus pin-hom zoo tib yam ceramic insulator muaj peev xwm qee zaum txuas ntxiv ua haujlwm hauv huab cua zoo; tab sis nyob rau hauv lub teeb los nag thiab huab cua pos huab, lub rwb thaiv tsev yuav poob sharply, ua rau kab tsis ua hauj lwm.

Tsis tas li ntawd, thaum muaj qhov tawg me ntsis hauv cov koob-hom ceramic insulator, txawm tias tus kws tshuaj xyuas kab tuav lub koob yees duab, nws nyuaj rau nrhiav qhov tsis xws luag, uas ua rau muaj kev phom sij rau txoj kab thiab ua rau qhov tsis zoo ntawm txoj kab. kev ua haujlwm.
