500KW electric load bank

Main parameters and fitting 1Resistance load equipment: 510KW 2Power factor: 1.0 3Test voltage: three phase AC voltage 380V 4Frequency: 50--60Hz 5Active power step: 1KW X 1 2KW X 2 5KW X 1 10KW X 5 20KW X 5 50KW X 7 6Normal Operational Conditions In summer the ambient temperature is 45,humidity is 90%.In winter the ambient temperature is -10, humidity is 50% 7ventilation power and the control power of the load bank are 3 phase 5 wire ( 380V + N + PE), total control power is 3 KW. 8Cooling mode: forced air convection, the fanner with axial-flow, the direction of the air is coming from the bottom and outgoing from the above. 9Controlling mode: Manual control. 10Load bank rated power error: thermal state: -4, cold state: -2. 11Protection device: over-current, short-current, over-load protection for the fanner. With over heat and less pressure protection for resistance pile. 12) the temperature for load bank outlet is about 250 13) IP for main return circuit: IP23 14) Insulation degree for motor: F 15) Working mode: continuous Main units 1, DC500V 100MΩ,AC2000V/,: ±2%. 1resistance tube: we selected self developed stereo-type resistance unit, the unit impedance is above DC500V 100MΩ,the withstand voltage is AC2000V/minitue,each resistance tube resistance error is ±2%. 2Main circuit AGRP 2.5 mm2,16 mm2 BVR . AGPP-60 +200 LC1. Specification of the cable: AGRP thermo stable wire2.5 mm2,16 mm2 and BVR cable. AGPP cable temperature is -60-+200 Contactor: LC1 series contactor of Schneider 3the fanner with axial-flow Working condition: ambient temperature: -10-+55 Relative humidity: 90% - 95% 4instrument: ACR200E with RS-485 Ambient temperature: ACR200E with RS-485 Relative humidity: ≤90% Precision: 0.5 5Transformer: CLJ-0.66 of Changjiang 6the frame are welded by the section steel with protection net for wind coming and going end. 7overall dimension: L1420 X W1000 X H1800
