Khoom Taw Qhia
Peb-Phase Compact Containerized Substation (1 - 12 MVA, 33 kV - 132 kV)
Npaj txhij xa tuaj-rau- khiav hauv tus qauv ISO 20 ft lossis 40 ft HC thawv, qhov no tag nrho - kev sib koom ua ke substation packs MV switchgear, peb -theem ONAN / ONAF transformer thiab LV faib rau hauv tub sab tub nyiag- thiab vandal- tiv thaiv IP54 steel plhaub- tsis muaj kev ua haujlwm hauv pej xeem, tsuas yog poob, kab, ua kom muaj zog.
Modular steel ncej txais kev ntsuam xyuas los ntawm 1 MVA mus rau 12 MVA ntawm 33, 66 lossis 132 kV nrog 25 kA / 1 s luv-lub sijhawm tiv taus; Lub tshuab nqus tsev lossis SF₆ thauj khoom- tawg hloov pauv ntxiv rau kev tshem tawm hluav taws xob hluav taws xob yog arc- qhov ua txhaum ntawm 31.5 kA / 1 s, thaum lub siab- lub ru tsev nyem thiab 50 ms arc- qhov hluav taws xob relays tiv thaiv ob tus neeg teb xov tooj thiab cov khoom muaj nqis.
Tsawg- poob CRGO core (< 1 W/kg no-load) and corrugated-tank cooling deliver 55 K rise at 45 °C ambient, cutting losses by 20 % versus site-built yards; dual-stage oil pumps boost ONAF capacity 40 % without enlarging footprint. Fire-resistant mineral oil or biodegradable ester fluid options, together with -40 °C cold-start heaters, make the unit suitable for deserts, tundra or offshore platforms. Internally partitioned HV, transformer and LV compartments provide Form 4b segregation; doors are interlocked so the container cannot be opened while the switch is live.
Integrated tiv thaiv relays (IEC 61850), Rogowski CTs thiab fiber ntau -optic hotspot sensors pub SCADA lossis huab dashboards rau qhov tiag-lub sijhawm kub, DGA thiab ib nrab- tso tawm trending, ua kom 15 % thaum muaj xwm ceev overload thiab kwv yees saib xyuas. Acoustic ua npuas ncauj thiab labyrinth cua inlets tuav suab nrov tsawg dua lossis sib npaug li 60 dB(A) ntawm 1 m- ntsiag to txaus rau hauv nroog substations. Thawv cov ces kaum khaws ISO lifting & twist -cov ntsiab lus xauv, tso cai rau crane, tsheb thauj mus los lossis tsheb ciav hlau thiab stackable cia rau ntawm qhov chaw. Seismic- tsim nyog rau 0.4 g, cua{14}} pov thawj rau 200 km / h thiab qhov siab tshaj - ntsuas rau 4 000 m, peb -theem compact containerized substation yog Hoobkas FAT- kuaj, roj- puv 6 teev, siv sijhawm li ntawm txhawb nqa los ntawm 25- xyoo tsim-lub neej lav.
