LGFZL-100 Load Bank Specification Main parameters and fitting 1Resistance load equipment: 111KW 2Power factor: 1.0 3Test voltage: three phase AC voltage 400V 4Frequency: 50--60Hz 5Active power step: 1KW X 1 step 2KW X 1 step 4KW X 1 step 8KW X 1 step 16KW X 2 step 32KW X 2 step 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), total control power is 1 KW. 8Cooling mode: forced air convection, the fanner with axial-flow: the direction of the air is coming and outgoing from the side, the control box is beside the wind input end(refer to the show drawing). 9Controlling mode: computer control. 10Load bank rated power error: thermal state: -4, cold state: -2. 11Protection device: over-current, short-current, over-load protection for the fanner. The short current and over load 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 16)Weight: 200KG Main units 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. 3TF. ; 5SJ6 Specification of the cable: AGRP thermo stable wire2.5 mm2,16 mm2 Contactor: 3 TF family contactor of Simens Circuit breaker: 5SJ6 family circuit breaker of Simens 3Transformer: CLJ-0.66 of Changjiang 4the frame are welded by the section steel,there is a wheel and easy to move. There is protection net for wind coming and going end. 5overall dimension: L900 X W1200 X H1000 We use computer key to operate, you just input the needed active power and the computer can calculate and operate the result then input the load by itself. You can increase the short time load. The load bank also can serve and print the test parameters. The parameters the computer will show: Three phase voltage, three phase current, three phase power, total power, three phase reactive power, total reactive power, three phase power factor, total power factor. 2Harmonic Offer each phase voltage, current value of 1 -50 times, harmonic voltage containing rate , with harmonic current rate , total harmonic distortion of voltage , current total harmonic distortion rate . . 3 Harmonic wave type: offer three phase voltage and three phase current wave type data. 12, 4 Impact test: 12 second impact time: catch the transient voltage, the frequency max value, the current min-value and recover time, can calculate the impact transient voltage deviation, the transient state frequency difference; 5 Unload suddenly test: 12 seconds unload time suddenly: May catch the transient voltage, the frequency maximum value, the current minimum value and recover time, can calculate unload the transient voltage deviation, the transient state frequency difference suddenly; 6 Records the wave: can carry on 1 second voltage to record the wave, each profile 128 spots.

Equipment approval The equipment approval carries on Our company, the equipment gets up transports the preceding week, Our company informs your firm to go to Our company to carry on one day-long equipment approval (and has training, according to equipment manufacture inspection standard and technical agreement approval). After the equipment approval finished, needed the bilateral signature to become effective. Quality insurance We are responsible to change or maintain the equipment under the warranty, if there is something wrong caused for the manufacturing defect or manufacturing equipment damage. But not include the damage caused by your negligence.
