Series resonance profile
Model: TKBPXZ
Name: ac withstand test, alternator ac withstand test, generator withstand test equipment
Generator Resonance Test System
Applicable object: it is mainly designed and manufactured for the ac withstand test of 11kV/30MW hydro-generator. The reactor adopts two separate designs.
Device composition: alternator ac voltage withstand test device mainly consists of variable frequency control power supply, excitation transformer, reactor and capacitor voltage divider.
Advantages of series resonance in power system applications:
1. The required power capacity is greatly reduced. Series resonance power is using the resonance reactor and the participants resonance capacitance generate high voltage and high current, in the whole system, the power only need to provide a part of the system energy consumption, the amount of power is only required test test the capacity of 1 / Q.
2. The weight and volume of the equipment are greatly reduced. Series resonance power, not only saves the heavy power regulating device and ordinary high power test transformer, power frequency and resonant excitation power supply need to test the capacity of 1 / Q, greatly reduce the system weight and volume, generally for the common test apparatus of 1/10-1/30.
3. Improve the output voltage waveform. Resonant power supply is a resonant filter circuit, which can improve the waveform distortion of output voltage and obtain good sinusoidal waveform.
4. Prevent large short-circuit current from burning fault points. In the series resonance state, when the insulation weakness of the test product is broken, the circuit immediately detuns, and the circuit current drops rapidly to 1/Q of the normal test current. Compared with shunt resonance or test transformer, the breakdown current immediately increases by dozens of times. The difference between short circuit current and breakdown current is hundreds of times. Therefore, series resonance can effectively find the insulation weakness, and there is no big short circuit current burn fault point.
5. No recovery overvoltage will occur. Try breakdown occurs, loss of resonance condition, high voltage, arc immediately put out, also immediately disappear and the recovery voltage to build process is very long, it is easy to power off before fall again flash voltage, the voltage of the recovery process is a kind of intermittent oscillation process of energy accumulation, the process is long, and there will not be any recovery over-voltage.
Series resonance is another name
Variable frequency resonance, frequency series resonance, transformer, series, series resonant series resonance test equipment, generator ac withstand voltage resonant booster unit pressure test device, motor, generator ac withstand voltage test unit, ac withstand voltage test system of the generator stator, 10 kv ac/dc withstand voltage test equipment, generator stator ac withstand voltage test system, variable frequency series resonance, frequency series resonance overvoltage withstand test device, the power frequency withstand voltage test device
Series resonance function
1, the generator ac withstand voltage test device has over voltage, over current, zero start, system mismatch (upon) protective functions, such as over-voltage over-current protection values can be based on user needs setting, try flash fell upon protection action and can take down upon voltage value, for experimental analysis
2. The weight of the whole device is very light, up to 40kg, which is convenient for field use
3. The device has four working modes, making it convenient for users to choose flexibly according to field conditions and improving test speed
The working mode is: automatic mode, manual mode, automatic tuning manual boost mode
4. Can store and print data in different places, and the data number stored is digital, so as to facilitate user identification and search
5, automatic device frequency sweep frequency starting point can be set freely within the prescribed scope, frequency sweep direction can up and down, LCD screen display scanning curve at the same time, the convenient user intuitive understanding whether find resonance point
6. DSP platform technology is adopted to facilitate the increase and decrease of functions and upgrades according to users' needs, and to make the man-machine interface more humanized
