Nruab nrab Voltage Motor Control Center

Medium Voltage Motor Control Center (MV MCC) lub tsev nruab nrab lub cev muaj zog pib, tswj cov khoom siv, thiab kev tiv thaiv relays rau nruab nrab voltage AC motors khiav hauj lwm ntawm 2.3kV txog 15kV. Ua los ntawm modular, compartmentalized hlau-cov qauv kaw, nws sib sau ua ke siab -voltage motor circuits thaum cais kev ua haujlwm txaus ntshai.

Standard Busbar Rating:Txog li 4000A

Luv -Circuit Withstand:Txog li 50kA rau 3s

Enclosure Options:NEMA 1, NEMA 3R, IP41, IP54

Internal Arc Rating:IEEE 3c/Type 2B (Accessibility B)

Modular kev faib tawm:Lub cev hlau thaiv lub cev cais lub busbar chamber, breaker/contactor compartment, thiab low-voltage control txee los tiv thaiv kev ua txhaum sab hauv.

Arc -Resistant Containment:Lub siab -relief flaps thiab top-mounted exhaust plenums direct arc flash zog deb ntawm cov neeg ua haujlwm, txaus siab rau IEEE C37.20.7 cov qauv.

Mechanical Interlocks:Interlock tshuab lub cev tiv thaiv racking lub tshuab nqus tsev contactor thaum lub voj voog nyob rau hauv load.

Thermal Monitoring:Integrated fiber ntau-optic sensors txuas ntxiv taug qab qhov kub thiab txias ntawm cov pob qij txha loj thiab cov cable txiav.

Roj & Roj:Main pipeline export twj, gas txhaj compressors, thiab refinery raw cov ntaub ntawv.

Mining & Minerals:Siab -Torque sib tsoo zeb, slurry thauj twj, thiab cov kiv cua hauv av.

Dej & Dej pov thawj:High- nqa cov twj tso kua dej thiab cov chaw nres tsheb loj hauv nroog.

Kev tsim hluav taws xob:Boiler pub twj tso kua mis, yuam cov cua ntsawj ntshab, thiab cov tshuab nqus dej.

Cov khoom sib dhos tau tsim ncaj qha rau qhov project Ib qho - Kab kos duab (SLDs) thiab cov neeg siv khoom tshwj xeeb. Custom engineering xaiv muaj xws li:

Starter Hom:Lub tshuab nqus tsev Contactor (FVNR/RVAT), Khoom -Lub Xeev Cov Hluav Taws Xob Hluav Taws Xob, lossis Nruab Nrab Voltage Variable Frequency Drives (MV VFD).

Kev tiv thaiv Relays:Kev sib xyaw ua ke nrog cov lej tiv thaiv relays los ntawm SEL, ABB, Schneider Electric, thiab Siemens.

Cable nkag:Configurable rau sab saum toj lossis hauv qab cable nkag, lossis kev hloov tsheb npav.

Footprint layouts:Rov qab-mus rau-rov qab los yog pem hauv ntej- nkag mus-tsuas yog kev npaj rau qhov chaw- txwv chav hluav taws xob.

Txee thav duab yog fabricated siv CNC turret punches thiab laser txiav tshuab, tswj cov txheej txheem seem tolerances nyob rau hauv ntxiv/minus 0.1 hli. Copper busbars undergo CNC dabtsi yog khoov, deburring, thiab nyiaj plating ntawm kev sib koom ua ke los txwv kev tiv thaiv kev tiv thaiv.

Txhua lub rooj sibtham dhau qhov yuav tsum tau kuaj lub Hoobkas ua ntej tso tawm:

Dielectric Withstand Voltage Test:Fais fab - zaus xeem siv nyob rau hauv lub ntsiab thiab pab circuits.

Main Circuit Resistance ntsuas:Micro-ohm ntsuas ntsuas ntawm busbar pob qij txha thiab contactor kev sib txuas.

Mechanical Operation Test:Yam tsawg kawg yog 50 lub voj voog ntawm cov txheej txheem rub tawm, kaw kev nyab xeeb, thiab qhov rooj sib cuam tshuam.

Secondary Wiring Verification:Txuas ntxiv thiab rwb thaiv tsev tiv thaiv kev sim ntawm tag nrho cov logic circuits.

Standards Ua raws li:Engineered thiab hom- sim ua raws li IEEE C37.20.3, IEEE C37.20.7, thiab IEC 62271-200.

Kev Tswj Xyuas Zoo:Ua raws li ISO 9001: 2015 cov txheej txheem ua haujlwm tau lees paub.

Project Documentation Package Supplied:

General Arrangement (GA) thiab Floor Plan Drawings

Schematic thiab Wiring Diagrams

Bill of Materials (BOM) nrog cov ntaub ntawv cov ntaub ntawv

Factory Acceptance Test (FAT) cov ntaub ntawv soj ntsuam thiab daim ntawv pov thawj calibration

Kev tiv thaiv:Cov chav nyob yog bolted rau hnyav-cov dej num steel skids, kaw hauv cov dej noo- cov hnab ntawv thaiv nrog cov khoom siv silica gel desiccant, thiab npog nrog cov cua sov-shrink polyethylene shrouds.

Kev tuav:Integrated lifting lugs thiab base channels yog engineered rau txheem crane rigging thiab forklift thauj.

Cov ntaub ntawv shipping:Cov npe ntim khoom, cov ntawv xa nyiaj ua lag luam, thiab daim ntawv pov thawj ntawm lub hauv paus chiv keeb yog nyob rau hauv cov ntaub ntawv tsis muaj huab cua sab nrauv.
