Thaum qhov tam sim no dhau los ntawm qhov tsis kam ntawm lub raj stainless hlau, qhov tam sim no ua haujlwm kom siv hluav taws xob thiab ua kom sov. Qhov tshwm sim no yog hu ua qhov cua sov ntawm qhov tam sim no. Muaj qhov sib txawv ntawm cov hlau nplaum muaj zog nyob rau hauv qhov chaw nyob ib ncig ntawm lub siab tam sim no tus neeg xyuas pib, thiab cov khoom siv hlau nyob rau hauv nws tsim kom muaj cua sov vim yog eddy tam sim no thiab hysteresis poob. Rau cov qauv hlau tsim lub kaw sib nqus sib nqus, xws li carbon steel casing, structural steel thav duab, thiab lwm yam, nws tseem ua tau kom induce circulating tam sim no thiab ua kom sov. Qhov kev poob thiab cua sov no yuav nce siab nrog qhov nce ntawm qhov tam sim no ntawm lub cable, uas yuav ua rau cov kab hluav taws xob rwb thaiv tsev puas tsuaj rau hauv cov hluav taws xob bushing thiab cuam tshuam rau kev nyab xeeb ntawm cov khoom siv hluav taws xob. Txhawm rau txhim kho lub cim ntawm kev poob thiab kev khiav cua sov, tiv thaiv lub kaw sib nqus hluav taws xob tsim los ntawm cov kab hluav taws xob los ntawm cov phab ntsa bushing thiab steel Cheebtsam, thiaj li tsis cuam tshuam rau cable rwb thaiv tsev poob thiab cuam tshuam rau kev nyab xeeb ntawm kev ua haujlwm.
Cov txheej txheem ib txwm siv cov yeeb nkab hlau nplaum sib nqus kom dhau los ntawm ib leeg-core cable kom tsis txhob tsim lub voj voog tam sim no yog txiav qhov sib txawv ntawm lub tes tsho steel raws li qhov ntev ntawm kev taw qhia los thaiv cov hlau nplaum, tab sis txoj kev no tsis yog. haum rau lub sijhawm uas xav tau airtight waterproofing. Txoj kev ncaj qha ntau dua yog siv cov khoom siv tsis sib nqus sib nqus los hloov lub tes tsho steel thiab cov khoom hlau, tab sis cov khoom siv hluav taws xob, kev ua kom sov thiab oxidation tsis kam ntawm cov khoom sib xyaw tsis zoo. Tooj, txhuas, aluminium alloy thiab lwm yam khoom siv hlau tsis sib nqus yog kim dhau los ua kev lag luam rau kev tsim kho engineering. Ua ke nrog cov teeb meem tiag tiag ntawm lub substation: txhua yam muaj zog, tiv thaiv corrosion, tsis muaj qhov xav tau tam sim no, thiab lwm yam., txoj hauv kev zoo los txhim kho cov teeb meem saum toj no yog siv austenitic stainless hlau casing thiab austenitic stainless hlau phaj kom tsis txhob muaj kev tsim ntawm ib qho chaw. kaw sib nqus Circuit Court thiab tiv thaiv cov khoom cua sov.
Stainless hlau yog hlau tsis yooj yim rau xeb. Qhov tseeb, qee qhov stainless hlau muaj ob qho tib si stainless thiab acid tsis kam (corrosion resistance). Austenitic stainless hlau yog stainless hlau nrog cov qauv austenitic nyob rau hauv chav tsev kub. Thaum cov hlau muaj li ntawm 18 feem pua Cr, Ni8 ~ 10 feem pua, thiab C txog 0.1 feem pua, nws muaj cov qauv austenite ruaj khov. Austenitic chromium-nickel stainless hlau suav nrog lub npe nrov 18Cr-8Ni steel thiab siab Cr-Ni series steel tsim los ntawm kev ntxiv Cr thiab Ni cov ntsiab lus thiab ntxiv Mo, Cu, Si, Nb, Ti thiab lwm yam ntawm lub hauv paus no. Austenitic stainless hlau yog cov hlau tsis muaj hlau nplaum thiab muaj zog toughness thiab plasticity, tab sis nws lub zog yog tsawg, nws tsis tuaj yeem ntxiv dag zog rau nws los ntawm kev hloov pauv theem, thiab nws tsuas tuaj yeem ntxiv dag zog los ntawm kev ua haujlwm txias. Yog tias S, Ca, Se, Te thiab lwm yam ntxiv, nws muaj kev ua haujlwm zoo. Ntxiv rau qhov corrosion kuj ntawm oxidizing acid nruab nrab, cov hlau no kuj tuaj yeem tiv thaiv corrosion ntawm sulfuric acid, phosphoric acid, formic acid, acetic acid thiab urea yog tias nws muaj cov ntsiab lus xws li Mo thiab Cu. Yog tias cov pa roj carbon ntsiab lus hauv cov hlau no tsawg dua 0.03 feem pua lossis muaj Ti thiab Ni, nws qhov kev tiv thaiv rau intergranular corrosion tuaj yeem txhim kho tau zoo. High-silicon austenitic stainless hlau muaj corrosion kuj zoo nyob rau hauv concentrated nitric acid.
