Kev soj ntsuam ntawm 1500A tawg peev xwm ntawm Fuse ceramic raj nyob rau hauv high voltage scenarios

Yuav kom ua tiav qhov kev sib tsoo ntawm 1500A, Fuse ceramic tubes yuav tsum tau tsom mus rau kev ua kom tau raws li peb qhov yuav tsum tau ua: kub kub stability, rwb thaiv tsev lub zog, thiab thermal conductivity efficiency. Nyob rau hauv cov nqe lus ntawm qhov kub thiab txias stability, hluav taws xob talc ceramic fuse lub cev tuaj yeem tiv taus qhov kub thiab txias ntawm 1200 degree, uas yog qhov tseem ceeb rau kev tua cov arc thaum lub 1500A tam sim no raug txiav. Yog tias siv cov khoom siv kub tsawg, lawv yuav ua rau yaj thiab ua rau arc to, ua rau lub cev tsis ua haujlwm;

Nyob rau hauv cov nqe lus ntawm rwb thaiv tsev lub zog, lub dielectric lub zog ntawm cov hluav taws xob ceramics tshaj 20kV / mm, uas yuav zoo tiv thaiv rwb thaiv tsev puas nyob rau hauv siab tam sim no ntawm 1500A thiab zam lub thib ob short circuits tom qab tawg; Lub thermal conductivity efficiency yuav tsum tau Fuse ceramic lub cev rau bussmann kom muaj thermal conductivity ntawm 1.5-2.0 W / (m · K). Cov thermal conductivity tau sai sai dissipate lub tshav kub generated los ntawm lub arc, tiv thaiv lub plhaub los ntawm cracking vim thermal shock, thiab xyuas kom meej stability ntawm Circuit Court breaking txheej txheem.

Fuse ceramic raj nrog lub peev xwm tawg 1500A muaj cov qauv kev ua haujlwm nruj.

Ua ntej, qhov kev tiv thaiv arc yuav tsum mus txog qib siab, thiab Square ceramic lub cev yuav tsum muaj peev xwm tiv taus arc yaig. Thaum lub sij hawm 1500A Circuit Court breaking txheej txheem, lub arc yuav tsis ua puas lub puab phab ntsa ntawm lub tes tsho, xyuas kom meej tias lub plhaub yuav rov qab siv tau yam xyuam xim;

Thib ob, nws muaj cov yam ntxwv thermal expansion tsawg. Lub thermal expansion coefficient ntawm talc ceramics siv nyob rau hauv hluav taws xob tsheb yuav tsum tsawg tshaj li los yog sib npaug zos rau 5 × 10 ⁻⁶ /℃kom tsis txhob deformation ntawm hluav taws xob steatite ceramic fuse lub cev thiab cuam tshuam rau Circuit Court breaking nyhuv thaum lub arc tshav kub nce sharply;

Thirdly, txaus mechanical impact resistance yuav tsum tau. Lub zog compressive ntawm lub casing yuav tsum tshaj 250MPa thiab muaj peev xwm tiv taus cov neeg kho tshuab cuam tshuam los ntawm arc tawg thaum lub sij hawm 1500A Circuit Court tawg los tiv thaiv kev puas tsuaj rau lub plhaub.

Ntxiv nrog rau cov khoom siv, kev tsim qauv tsim kom zoo ntawm Steatite ceramic rau EV fuse kuj tseem ceeb rau kev txhim kho lub peev xwm ntawm 1500A. Nyob rau hauv cov nqe lus ntawm kab noj hniav ntim tsim, lub sab hauv kab noj hniav ntim ntawm 1500A fuse vaj tse yuav tsum muaj ntau tshaj los yog sib npaug zos rau 15cm ³, nrog rau qhov chaw txaus rau lub arc kom tag nrho nthuav thiab txias, tsis txhob arc reignition thiab ua kom tiav Circuit Court breaking;

Nyob rau hauv cov nqe lus ntawm tshav kub dissipation channel layout, ntxiv 3-4 axial tshav kub dissipation slots ntawm lub sab nrauv phab ntsa ntawm lub plhaub yuav ua rau kom lub tshav kub dissipation cheeb tsam los ntawm 30%, accelerate arc tshav kub dissipation thaum lub sij hawm 1500A Circuit Court breaker, thiab txo lub plhaub kub; Nyob rau hauv cov nqe lus ntawm kev txhim kho kev sib khi, IP65 qib silicone gaskets yog siv nyob rau hauv cov chaw nres nkoj vaj tse kom zoo thaiv cov plua plav sab nraud thiab cov dej noo los ntawm kev nkag mus, kom ntseeg tau tias Din hom steatite ceramic HRC fuse lub cev muaj peev xwm tswj tau qhov ruaj khov 1500A Circuit Court breaking peev txawm nyob rau hauv ib puag ncig hnyav.

Lub Ceramic HRC fuse lub cev nrog lub peev xwm tawg ntawm 1500A yog dav siv nyob rau hauv ntau yam siab -voltage hluav taws xob tshuab, tshwj xeeb tshaj yog ua lub luag haujlwm tseem ceeb hauv kev tawm siab siab - kawg teb. Nyob rau hauv 800V hluav taws xob tsheb roj teeb pob, lub plhaub hluav taws xob ceramic tuaj yeem ua kom muaj kev nyab xeeb ntawm kev cuam tshuam tam sim no, tiv thaiv lub roj teeb pob thiab tag nrho cov hluav taws xob ntawm lub tsheb;

Nyob rau hauv lub zog cia converters saum toj no 500kW, lub Alumina ceramic sleeve tube rau high voltage EV fuse tau zoo lis 1500A surge tam sim no, zam kev puas tsuaj rau cov khoom los ntawm surges; Hauv 480kW siab- lub zog them chaw nres tsheb, lub tshuab hluav taws xob talc ceramic fuse lub cev tuaj yeem ua haujlwm ruaj khov nyob rau hauv lub sijhawm ntev - lub sijhawm ua haujlwm siab, ua kom muaj kev nyab xeeb thiab ua haujlwm zoo ntawm lub chaw them nyiaj. Cov xwm txheej no tau vam khom rau qhov muaj peev xwm tawg tau zoo ntawm lub plhaub ceramic los tiv thaiv kev ruaj ntseg.

Yog hais tias koj xav paub cov ncauj lus kom ntxaws parameters thiab customized kev daws teeb meem ntawmFuse ceramic tubes, los yog muaj lus nug txog 1500A Circuit Court breaking peev xwm ntsig txog cov khoom, thov koj xav tiv tauj peb txhua lub sijhawm. Peb yuav muab kev txhawb nqa kev tshaj lij rau koj thiab cov khoom lag luam raug daws los pab ua haujlwm ruaj khov ntawm koj lub siab -voltage hluav taws xob.
