load bank equipment

Main parameters and fitting 1Resistance load equipment: 212.5KW 2Power factor: 1.0 3Test voltage: three phase AC voltage 415V 4Frequency: 50--60Hz 5Active power step: 2.5KW X 1 step 5KW X 2 step 10KW X 2step 20KW X 5 step 40KW X 2step 6Normal Operational Conditions In summer the ambient temperature is 45,humidity is 90%.In winter the ambient temperature is -20, humidity is 50% 7ventilation power and the control power of the load bank are 3 phase 5 wire ( 380V+N+PE). 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 short circuit and over load protection for resistance pile. 12) The temperature for load bank outlet is about 250, temperature for enclosure is 5-10 higher then normally temperature, with partition for resistor and enclosure. 13) IP Degree for main loop IP20 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%2 2the fanner with axial-flow 3instrument: ATREMC instrument ACR200E with RS-485 5Transformer: ALH-0.66 of Changjiang of Jiangyin city
