Product Description
Summary
The device mainly AC voltage withstand test design for 10kV, 35kV, 110kV, 220kV, substation and line of all electric main equipment.Reactor with multiple separate design, Not only can meet the requirements of equipment testing conditions high voltage, small current, and can meet the requirements of low voltage AC voltage withstand test, has a wider scope of application.
The device is mainly composed of variable frequency control power supply, transformer, reactor, capacitor divider.
Advantages
1.The required power supply capacity greatly reduced. The series resonant power supply is the use of resonance reactor and tested product capacitance resonant generate high voltage and large current, in the whole system, power supply only needs to provide the system active power consumed, therefore, the power required tests only test the capacity of 1/Q.
2.The weight and volume of the equipment is greatly reduced. The series resonant power supply, not only saves power heavy pressure adjusting device and a common power frequency testing transformer, and resonant excitation power supply, just need to test the capacity of 1/Q, which makes the system weight and volume is greatly reduced, generally for ordinary test device of 1/10-1/30.
3.Improving the output voltage waveform. Resonant power supply is resonant filter circuit, the output voltage waveform distortion can improve, sinusoidal waveform is obtained very good, can effectively prevent the harmonic peak error on the sample breakdown.
4.To prevent fault point of a short circuit current burn. In the series resonant state, when the sample's insulation weakness breakdown,the circuit immediately out of resonance, the loop current decreased rapidly to normal test current 1/Q. And parallel resonance or test transformer to withstand voltage test, the breakdown current immediately rise several decuples of normal, both compared, the short-circuit current and the breakdown current is hundreds of times. So, the series resonance can effectively find weaknesses in the insulation, and there is no large short-circuit current of fault point suffering burns.
5.There will be no recovery over voltage.
when the sample occurs breakdown, due to the loss of resonant conditions, high voltage also disappear immediately, arc immediately extinguished and the recovery voltage, re-establishment process is very long, very easy to flashover voltage again before disconnecting the power, the voltage recovery process is a batch process of accumulation of energy, the process is long, but also, there will be no recovery over voltage.
Function and characteristic
1.Device has overvoltage, overcurrent, zero start, detuning (flashover) protection's function, overvoltage and overcurrent protection value can be based on user needs setting, when the sample flashover, flashover protection action and can record the flashover voltage value, for experimental analysis.
2.The weight is light, the maximum not more than 65kg, is convenient for field use.
3.The device has three modes of operation, convenient for the user according to the scene situation flexibly, improve the test speed.
Working mode: full automatic mode, the manual mode, the manual mode of automatic tuning
4.It has functionn of stored and remote printing data , stored data number is a number, convenience of help users identify and find.
5.When the device automatic sweep frequency ,the frequency starting can be within the specified scope set arbitrarily, sweep direction can be upward, downward selection, at the same time, large LCD screen display scan curve, is convenient for users to intuitively understand whether to find the resonance point.
6.Using the DSP platform technology, can according to user needs change and upgrade, also make the human-computer interface more humane.
