Product Name: 11kv 4MW Resistive Load Bank for Gas Turbine Testing Model NO.: AC/DC Load Bank Rated Voltage: 11kv 3phase 50Hz/60Hz Load Wire Connection: 3phase 3wire Power Factor: 1 Cooling: Forced Air Cooling Control Mode: Manual or Software Rated Power: 4MW Dimension: 9150*2350*2591mm Trademark: Triumph load Transport Package: Inner: Plastic Film Wrapped Outside: Wooden Case Specification: ISO9001: 2008 Origin: Shijiazhuang, Hebei, China HS Code: 9030390000 Product Description 2.1 Measuring FunctionSteady-state Test: load power in rated range, measure generator steady-state 3 phase voltage, current, active power, reactive power, apparent power, power factor, frequency, and running time.2.2 Dummy Load FunctionWorking principle and pattern: Dynamic adjustment principle, when real load is no more than X% (XkW) output power of DG set, load bank will automatically add load in 5 seconds to make sure real load power + load bank power ≥XkW and remove all load power in 5 seconds when real load power no less than XkW.3 line LED multi-function meter can display real-time voltage and current of three phase and each phase, resistive power, power factor, apparent power, frequency and running time of generating set.User can pre-set the power then press the master load button.Control mode: Automatically load/unload.Through RS485 connect PC and load bank, the real-time data can be transferred to PC, use data management software, data can be formed into curves, exported to EXCEL or JPG file.2.2 Control Mode(1) Control Mode: local, remote or intelligent control(software) for choosing.(2) Local Control: local control panel with several power steps, load or unload by switch on-off and read parameter values from measuring meter.(3) Remote Control:through the switch in the remote control box, control the load over a long distance.(4) Intelligent Control: through data processing software, realize all the test functions, display, record and manage the testing data, and generate curves, graphs and tables can be printed.(5) Control Mode Interlock: with control mode switch, no matter chooses which mode, operation of other mode is invalid, avoid the clash.2.3 Intelligent Load Function(1) Communication Mode: using photoelectric isolated RS485 communication serial port connect to PC, and with great anti-interference performance to make system control stable. Through converts like USB or RS232 realize communication protocol conversion.(2) Load Mode: steady-state load (manual load, preset load and automatic load) and transient state load (instant load and instant unload).(3) Manual Load: input power and power factor, and load according to the preset value.(4) Preset Load: input generator related parameters, then choose the preset proportion from 0% 25%, 50%, 75%, 100% or other available order and calculate the power value automatically and realize rapid load.(5) Automatic Load: set several load stages and duration, then complete the process according this stages automatically. Pause at any time or start to next stage in the load process.(6) Parallel Test: several load banks work in parallel, the parallel test via software. Parameters of each set can be displayed in each meter and total parameter values can be displayed and recorded.2.6 Technical ParameterSystem Parameter Rating voltage/frequency6.6KV, 3 phase 3 wire 50HzMax Load PowerResistive Load: 4MW Load ResolutionTotal 8 steps 500kW,500kW,500kW,500kW,500kW,500kW,500kW,500kW Power Factor1Load Tolerance (each step)±5%Load Tolerance (overall)±3%Fan &Control VoltageExternal AC 3 phase 4 wire, 380V/50HzWire Connection Load bank input--Copper bar (star coupling "Y")Control power input--Connector-barCommunication InterfaceRS485,RS232InsulationFMax Protection GradeIP55Duty CycleContinuous CoolingForced air cooling, by Axial Fan; horizontal inlet air, vertical exhaust coolingEnclosureContainer type,with a ladder, air inlet and outlet with mesh enclosure and protection doorInternal LightingAdequate internal lighting will be providedTransportationHoisting, there are lifting lug in top of casingColorGrey RAL7035 or as requiredDimensionsabout 9150mm×2350mm×2591mm(L×W×H)Operating Environment ParameterAmbient Temperature-10ºC~+50ºCRelative Humidity≤95%Atmospheric Pressure86~106kPaBrands of Main ComponentsContactorXiguangPLCSiemensFuseChuantaiAlloy Resistor(self-developing)Data Processing Software(self-developing)
