Khoom Taw Qhia
Txhua lub tooj liab lossis txhuas bar yog lub tshuab nqus tsev vacuum-encapsulated hauv nplaim hluav taws-retardant, halogen-dawb epoxy, tsim ib qho -daim, txij nkawm-dawb module ntsuas IP68/IK10 thiab impervious rau plua plav, ya raws, lossis tshuaj vapors. Lub cev resin tiv taus 950℃rau 180 min (IEC 60331) thiab tso tawm xoom cov pa roj carbon monoxide, ua rau lub cev zoo tagnrho rau tsev kho mob, subways, cov ntaub ntawv hauv tsev thiab cov chaw sab nraud uas muaj kev nyab xeeb hluav taws kub.
Tsawg-cov vaj tse profile (tsuas yog 90 mm × 160 mm rau 2500 A) txiav qhov chaw ncej 30% piv rau cov pa cua ib txwm muaj, thaum lub plhaub 2 hli txhuas ntxiv rau ntau dua lossis sib npaug li 0.9 W / m·K epoxy muab 35 % zoo dua cov cua sov dissipation, ua kom kub txog li 5 txog 5 ambient thiab ntau dua. Nyiaj-plated, caij nplooj ntoos hlav{12}}loaded hu tuav <15 µΩ sib koom ua ke rau ntau xyoo; bolts raug tshem tawm, yog li thermal cycling tsis tuaj yeem loosen pob qij txha.
luv-circuit tiv taus 100 kA / 1 s; ua tau -hauv arc- cov phaj txhaum quench ionized gas hauv 15 ms, tiv thaiv cov khoom siv hluav taws xob. Coj mus rhaub-tawm chav nyob los ntawm 25 A txog 1250 A xauv nyob rau hauv lub zog muaj zog- tsis muaj kev kaw-thiab tuaj yeem hloov pauv hauv feeb rau kev hloov kho kab.
Ntev yog muab lub Hoobkas - nrum thiab hluav taws kub - nres; snap-nyob rau hauv hangers pub 3 m spans, txo steelwork 25%. Integrated IoT kub sensors pub SCADA lossis mobile dashboards, ua kom 10% thaum muaj xwm ceev overload thiab kwv yees saib xyuas. Ua raws li IEC 61439-6, UL 857, GB / T 7251.6, seismic 0.4 g, thiab qhov siab 4000 m, lub kaw lus tau npaj kom muaj zog 24 teev tom qab xa khoom thiab nqa 25 xyoo tsim lub neej lav.
