Cov khoom nta thiab kev ua haujlwm ib puag ncig
1. Lub switchgear overcomes lub shortcomings ntawm tus thawj switchgear.Tus tshiab handcart-type switchgear tsim los ntawm lub tuam txhab muaj kev tiv thaiv ua tiav, kev ua haujlwm siab, thiab kev saib xyuas yooj yim thiab yooj yim.Me me thiab lub teeb yuag.
2. Lub txee hloov pauv yog tsim los ntawm lub txee thiab lub tawb nqa khoom.Nws tau muab faib ua chav nqa tes, chav tsev busbar, chav cable, thiab chav relay los ntawm kev muab faib.Lub tawb nqa khoom muaj ob txoj haujlwm rau kev sim thiab ua haujlwm.Chav tsev nqa khoom yog cais los ntawm chav cable los ntawm ib lub phaj insulating txav, tshwj xeeb tshaj yog yooj yim thiab nyab xeeb thaum tu.Lub tsheb pauv tus nqi yog 100%, txo lub sijhawm txij nkawm thiab txhim kho cov khoom siv hluav taws xob zoo.Lub handcart slideway yog qhov tseeb thiab hloov tau los xyuas kom meej tias lub tawb nqa khoom tsis txav mus rau hauv thiab tawm, thiab qhov chaw taw qhia kev tsheb ciav hlau tau teeb tsa los ua kom cov ntsaws txuas ntxiv yog thiab txhim khu kev qha.
3. Kev tiv thaiv kev ua haujlwm ntawm lub switchgear, tom qab xyoo ntawm kev siv hauv cov mines, cov khoom tuaj yeem ua tau raws li kev tiv thaiv kev xaiv ntawm ntau lub hom phiaj, nruab nrog cov xau, rwb thaiv tsev saib xyuas, undervoltage, luv Circuit Court, overcurrent lag luam overvoltage, thiab tseem tuaj yeem siv nrog Cov chaw taws teeb tswj, cov chaw taws teeb sib txuas lus, telemetry, thiab lwm yam. Cov khoom siv tiv thaiv tsis siv neeg muaj peev xwm yuav nruab nrog cov khoom siv tiv thaiv me me tam sim no hauv av.
A series ntawm mining microcomputer tiv thaiv thiab ntsuas thiab tswj cov cuab yeej tuaj yeem xaiv.Cov kev tiv thaiv muaj kev sib txuas lus interface.Tag nrho cov ntaub ntawv raug xa mus rau qib siab saib xyuas lossis kev hloov kho hauv lub sijhawm tiag tiag los ntawm kev sib txuas lus network."Five remote" muaj nuj nqi.
Lub luag haujlwm tiv thaiv:
1) Kev tiv thaiv luv luv
2) Kev tiv thaiv overload
3) Zero sequence overcurrent tiv thaiv
4) Zero sequence overvoltage tiv thaiv
5) Overvoltage thiab undervoltage tiv thaiv
Nws kuj muaj cov haujlwm xws li kev nco tsis raug, kev nug txog kev txhaum, thiab kev kuaj xyuas tus kheej.
Environmental tej yam kev mob:
Lub switchgear yuav tsum ua haujlwm ib txwm nyob rau hauv cov xwm txheej hauv qab no:
a) Qhov siab: 1000m;b) Ambient
kub: -20 ℃ ~ 40 ℃;
c) txheeb ze humidity: 95%;
nyob rau hauv ib puag ncig chav;
