Rectangular siab precision residual tam sim no transformer
S/N: LO-ORCT-XX
Product Overview:
Cov kab ntawv lo-XX tshaj tawm cov khoom siv hluav taws xob tam sim no (RCT)
Lub kaw lus ntawm cov koob no yog tsim los ntawm ib puag ncig tus phooj ywg nplaim hluav taws-retardant ABS engineering yas, high-permeability nanocrystalline mos magnetic khoom, muab siab precision, zoo tshuav nyiaj li cas, compact loj, siab rwb thaiv tsev zog, muaj zog cuam tshuam, thiab yooj yim installation. Nws ua haujlwm ruaj khov thiab ruaj khov hauv qhov chaw sab hauv tsev.
LO-ORCT-XX Rectangular Series suav nrog tsib qhov tshwj xeeb tsim nyog rau circuits nrog busbar widths mus txog 300mm, ua tau raws li qhov xav tau ntawm kev kuaj xyuas cov seem seem hauv Circuit Court faib mus txog 1000A.
Cov koob no tau txais kev tsim qauv zoo sib nqus sib nqus, teeb tsa cov txheej txheem coil winding raws li cov yam ntxwv ntawm cov khoom sib nqus, thiab sib txuas nrog cov qauv tiv thaiv kev cog lus. Qhov no tso cai rau cov khoom kom ua tau raws li qhov yuav tsum tau ua rau qhov raug, rhiab heev, thiab kev sib npaug ntawm kev ua haujlwm thaum tuav qhov loj me. Cov khoom kho cov taw nta ib lub qauv tsim, uas tsis tsuas yog txo cov nqi thaum lub sij hawm ntim thiab kev thauj mus los tab sis kuj muab kev tiv thaiv zoo rau cov qauv kho.
Rau qhov loj dua specifications ntawm cov khoom ntsia tau rau hauv tooj liab bar circuits, vim qhov hnyav hnyav ntawm cov khoom, nws raug nquahu kom siv lub tiaj mounting bracket kom ruaj khov ntawm lub installation. Txhawm rau ua tiav cov txiaj ntsig kev soj ntsuam zoo dua, nws yog qhov zoo tshaj plaws los tso lub busbar nyob rau hauv nruab nrab ntawm lub transformer lub duab plaub los ntawm lub qhov, tsis txhob muab lub busbar ze ze rau sab hauv phab ntsa ntawm cov khoom ncaj nraim.
Lub davhlau ya nyob twg txoj haujlwm ntawm cov koob no kuj tau txais tus qauv rail qauv tsim, tso cai rau lub teeb liab ua vaj tsev nyob yuav tsum tau clamped rau saum nws. Qhov no muab cov khoom muaj peev xwm nthuav dav dua.
Nta:
- Resin casting txheej txheem, zoo heev waterproof thiab noo noo-pov thawj kev ua tau zoo
- Nws muaj peev xwm overloaded muaj zog thiab tuaj yeem overloaded 20 npaug ntawm qhov ntsuas tam sim no ntev yog tias tsim nyog.
- Cov yam ntxwv zoo sib npaug, cov khoom me me ua tau raws li qhov ntsuas lub tswb ntsuas qhov xav tau ntawm 50mA
- High precision: precision theem {{0}}.5/1.0/3, xaiv compact tsim, me me
Ib txwm siv thiab kev teeb tsa kev teeb tsa:
- Installation qhov chaw: sab hauv / sab nraum zoov. ambient kub -40 degree~ +45 degree
- Nws raug pom zoo tias cov av noo ntawm ib puag ncig yuav tsum tsis txhob siab tshaj 80%
- Qhov siab tsis tshaj 3000m
- Atmospheric tej yam kev mob: Tsis muaj kuab paug hnyav, corrosive thiab explosive media nyob rau hauv cov huab cua
- Ib puag ncig tsis muaj kev vibration thiab poob siab. Cia kub: -20 degree ~ 75 degree
