Qauv
Cov khoom no muab faib ua ob ntu: txee thiab VCB. Lub txee yog ua los ntawm bent steel phaj thiab sib dhos nrog bolts tom qab txau. Raws li cov yam ntxwv ua haujlwm, nws tuaj yeem muab faib ua plaub ntu: chav tsheb npav me me, chav ntsuas hluav taws xob relay, chav VCB, chav cable thiab chav tsheb npav, txhua qhov yog sib cais los ntawm cov hlau hauv av. Kev tiv thaiv qib ntawm lub qhov rooj hloov pauv yog IP4X; Thaum lub qhov rooj VCB qhib, qhov kev tiv thaiv qib yog IP2X.
Lub switchgear muaj cov txheej txheem tseem ceeb xws li cable inlet thiab qhov hluav taws xob, nyiaj siv ua haujlwm inlet thiab qhov hluav taws xob, kev sib txuas hauv tsheb npav, kev sib txuas, kev hloov hluav taws xob, thiab hluav taws xob ntes. Lub busbar txais cov rwb thaiv tsev sib xyaw, thiab cov txheej txheem sib txuas thiab cov khoom sib txuas tau nruab nrog lub tes tsho insulating ua los ntawm cov khoom siv hluav taws xob. Cov txee uas nyob ib sab ntawm lub busbar tseem ceeb yog sib cais los ntawm lub tes tsho busbar, uas tuaj yeem tiv thaiv kev sib tsoo kom tsis txhob kis tau thiab ua lub luag haujlwm pabcuam pabcuam rau lub tsheb loj. Lub chav cable yog nruab nrog lub ntiaj teb hloov, overvoltage tiv thaiv ntaus ntawv, thiab lwm yam.
Muaj ib lub hlau ruaj ntseg kaw rau pem hauv ntej ntawm lub thawv tiv tauj. Lub kaw lus ruaj ntseg sab saud thiab qis dua tau qhib thaum VCB txav los ntawm qhov kev sib txuas / kev sim mus rau txoj haujlwm ua haujlwm, thiab kaw thaum VCB txav mus rau qhov sib txawv, cuam tshuam zoo ntawm qhov hluav taws xob siab. Kev sib cuam tshuam ntawm lub ntsiab hloov, VCB, lub ntiaj teb hloov thiab lub qhov rooj hauv lub txee txais yuav tsum tau siv cov txheej txheem kev sib tshuam kom ua tau raws li "tsib tiv thaiv" kev ua haujlwm.
Lub Circuit Court breaker txais ib tug ntsia hlau qws tsav propulsion mechanism thiab ib tug overrunning clutch. Cov ntsia hlau qws txiv ntseej pub tshuab tuaj yeem ua haujlwm yooj yim txav VCB ntawm txoj haujlwm kuaj thiab txoj haujlwm ua haujlwm. Nrog kev pab los ntawm tus kheej-locking cuab yeej ntawm cov ntsia hlau ntsia hlau ntsia hlau, VCB tuaj yeem txhim khu kev ruaj ntseg xauv hauv qhov chaw ua haujlwm los tiv thaiv VCB los ntawm kev sib tsoo los ntawm kev khiav tawm vim hluav taws xob. Lub overrunning clutch ua haujlwm thaum VCB txav rov qab mus rau qhov chaw sim thiab thaum nws mus txog qhov chaw ua haujlwm. Nws ua rau kev khiav hauj lwm ncej thiab cov ntsia hlau ncej txiav tawm thiab tsis ua haujlwm, uas tuaj yeem tiv thaiv kev ua haujlwm tsis zoo thiab ua rau lub tshuab pub mis puas. Lwm cov VCBs siv lever feed mechanism. Txoj haujlwm kuaj ua haujlwm raug kaw los ntawm kev tso tus pins.
Tag nrho qhov ntev ntawm lub txee yog: W × D × H (mm): 1400 × 2800 × 2600
