Tuav High-Voltage Cartridge rhaub - Kev nyab xeeb thiab kev ua haujlwm xav tau

Feem ntau cov tshuab tso cua sov ua haujlwm nrog cov pa hluav taws xob zoo li 120V, 230V, lossis 480V. Tab sis qee qhov kev siv xav tau ntau dua qhov hluav taws xob, feem ntau yog rau kev ua haujlwm lossis ua haujlwm nrog cov khoom siv hluav taws xob tam sim no. Cartridge rhaub uas tuaj yeem tswj tau 600V, 1000V, lossis ntau dua yog txawv ntawm lwm hom cua sov. Cov txheej txheem rwb thaiv tsev yuav tsum muaj zog txaus kom tsis txhob arcing, thiab txoj hauv kev uas nws tau teeb tsa yuav tsum tau xav txog qhov kev ntxhov siab ntxiv ntawm hluav taws xob.

Magnesium oxide rwb thaiv tsev yog qhov tseem ceeb tshaj plaws ntawm lub siab -voltage cartridge rhaub. Standard MgO muaj lub zog dielectric siab, tab sis nws ua haujlwm zoo npaum li cas nyob ntawm seb nws zoo npaum li cas. Arcing tuaj yeem tshwm sim hauv MgO yog tias muaj lub qhov lossis tawg hauv nws. Cov neeg tsim khoom siv MgO uas tau ua tib zoo kho los txhim kho nws cov yam ntxwv dielectric rau siab -voltage siv. Lub siab siv los cog cov hmoov yog siab dua, thiab cov hmoov yog qee zaum kho nrog lub hoover kom tshem tawm cov hnab ntim cua. Internal arcing yuav ua rau lub siab -voltage rhaub uas siv ib txwm MgO tawg.

Qhov ntev ntawm qhov chaw txias yog qhov tseem ceeb tshaj thaum qhov hluav taws xob siab. Kev hloov pauv los ntawm cov xaim hluav taws xob sab hauv mus rau cov hlau lead tuaj yeem yog qhov tsis muaj zog. Yog tias cheeb tsam txias yog luv luv, qhov voltage gradient mus rau qhov kawg tuaj yeem siab dua li MgO lub zog dielectric, uas tuaj yeem ua rau tawg. Ntxiv rau qhov chaw txias yuav txo qhov voltage gradient thiab muab kev nyab xeeb rau koj. Cov cheeb tsam txias ntawm 25mm lossis ntau dua yog nquag ntawm qhov hluav taws xob ntau tshaj 600V.

Cov hlau lead yuav tsum muaj peev xwm tuav tau high voltage. Qhov ntsuas hluav taws xob rau tus qauv txhuas hlau rwb thaiv tsev yuav yog 300V lossis 600V. Rau siab dua voltages, koj xav tau tshwj xeeb high -voltage leads nrog thicker rwb thaiv tsev los yog silicone roj hmab tebchaw. Txhawm rau tiv thaiv corona tawm, uas tshwm sim thaum muaj hluav taws xob ionises huab cua nyob ib puag ncig tus neeg xyuas pib, tsim ozone thiab rhuav tshem cov rwb thaiv tsev nyob rau lub sijhawm, qhov kev txiav tawm ntawm lub tshuab rhaub lub cev yuav tsum raug kaw. Corona tuaj yeem rhuav tshem cov hlau lead hauv ob peb lub hlis xwb.

Thaum txhim kho siab - lub tshuab cua sov, koj yuav tsum tau ceev faj tshwj xeeb. Koj yuav tsum khaws cov coj mus deb ntawm cov npoo ntse thiab lwm cov xov hlau. Kev tiv thaiv arcing yog qhov yooj yim raws li qhov chaw txaus ntawm qhov siab -voltage leads thiab av. Qee qhov xwm txheej, kev siv cov hlau thaiv kev tiv thaiv los yog muab cov hlau lead hauv av hauv av ua rau muaj kev pheej hmoo. Cov kab noj hniav yuav tsum huv thiab qhuav. Txhua qhov av lossis cov khib nyiab hauv qhov hollow tuaj yeem ua rau cov kab hluav taws xob los ntawm lub tshuab cua sov rau hauv av, uas tuaj yeem ua rau cov dej xau tam sim no uas ua rau muaj kev nyab xeeb.

Nyob rau hauv high voltage, grounding yog tseem ceeb heev. Kev ua txhaum hauv av uas tuaj yeem ua rau muaj kev ntxhov siab ntawm 230V tuaj yeem ua rau muaj kev puas tsuaj loj ntawm 1000V. Lub tshuab rhaub cua sov yuav tsum tau muab tso rau hauv av kom zoo, thiab txoj hauv av yuav tsum tau kuaj xyuas tsis tu ncua. Siv lub hauv av-kev cuam tshuam Circuit Court cuam tshuam (GFCI) lossis cov khoom siv tam sim no (RCD) ua rau siab -voltage systems yuav ua rau koj muaj kev nyab xeeb tiv thaiv cov dej xau.

Kev paub qhia tias koj yuav tsum tsis txhob sim ua kom siab -voltage cartridge heaters koj tus kheej. Lawv yuav tsum tau ua tib zoo npaj, ua rau tus qauv siab, thiab txhim kho kom raug. High- lub tshuab hluav taws xob hluav taws xob zoo dua thaum cov qauv no tau ua tiav vim tias lawv siv tsawg dua tam sim no rau tib lub zog, uas txo qis I²R poob hauv cov khoom siv. Tab sis tsis muaj ntau chav rau qhov yuam kev. Yog tias qhov rwb thaiv tsev tsis zoo, lub rhaub dej ua haujlwm OK ntawm 230V tuaj yeem ua rau sab hauv ntawm 1000V. Yog tias koj xav siv hluav taws xob siab, nws yog ib qho tseem ceeb uas yuav tau ua hauj lwm nrog ib lub tuam txhab uas ua rau siab -voltage heaters thiab ua raws li lawv cov lus qhia installation raws nraim.
