WUHAN HUAZHONG HUANENG HIGH VOLTAGE&TECHNOLOGY DEVELOPMENT CO., LTD.  

Product Name: Hnbpxz-1800 Variable Frequency Resonant Test Device High Voltage AC Resonance Voltage Withstand Test Setup Model NO.: HNBPXZ-1800 Origin: Wuhan Product Description IntroductionFrequency Modulated AC Series Resonance Test Deviceis mainly designed and manufactured for the AC withstand voltage test of all electrical main equipment such as 10kV~220KV cable and the following main power transformer and bus switch. The reactor adopts multiple separate designs, which can meet the requirements of high voltage and low current equipment test conditions, and can meet the requirements of low voltage AC withstand voltage test such as 10kV cable. It has awide range of application.ParametersItemHNBPXZ-1800FunctionSeries resonance test deviceRated VoltageSuitable for 10 kV AC voltage withstand test of cable and motorSuitable for 35kV voltage withstand test of cableOutput voltage waveform distortion rate<1.0%Continuous working time60 minutes in rated conditionDevice quality factorQ: 30~80Input PowerSingle phase 220V/three phase 380VFrequency range20Hz~300HzMeasurement Accuracy1%Features1. The device has protection functions such as overvoltage, overcurrent, zero start, system detuning (flashover), etc. Overvoltage and overcurrent protection values can be set according to user needs. When the sample is flashed, the flashing protection action can be recorded. The flashover voltage value is used for experimental analysis2. The weight of the whole unit is very light, and the maximum weight is no more than 40kg, which is convenient for on-site use.3. The device has three working modes, which is convenient for users to flexibly select according to the site conditions and improve the test speed. Working mode: Fully automatic mode, manual mode, automatic tuning manual boost mode,4. It can store and save the data as number, which is convenient to help users identify and find.5. When the device is automatically swept, the frequency starting point can be arbitrarily set within the specified range. The sweeping frequency direction can be selected upwards and downwards. At the same time, the LCD large screen displays the scanning curve, which is convenient for the user to intuitively know whether to find the resonance point.6. The device has aunique intelligent debugging system. When the user does not know how to assemble the reactor when facing the unknown test object, he only needs to use the debugging program of the device to tell the user how to assemble the equipment to work. In most cases, the problem that the resonance point can not be found due to the improper combination matching of the system is solved, which greatly improves the work efficiency.
