Resonant test set

Product Description

�

The device is mainly aimed at consumers *0kV, **0 kv cable, **0kV *5kV, under compression experiment design and manufacture of substation exchanges. Reactor using separate design not only can meet high voltage, low current equipment test conditions request, and can satisfy the consumers *0kV cable such as low voltage AC pressure test requirements, has a wide scope, earth, city and county level shall high-voltage test departments and electricity installation, repair engineering unit ideal compression test equipment.
The device is mainly VFC source, excitation transformer, resonant reactor, capacitance bleeder composition.

Series resonance in the power system application advantages:

1. Reduce the power capacity required. By the resonance of network (power is tasted capacitance reactors and be try resonant produce high voltage and current in the whole system, only need to provide system, the supply of parts of the meritorious consumption, therefore, test the power needed only test capacity of the 1 / Q.
2. The weight and volume of the equipment is greatly reduced. Power, not only of network (saves the heavy pressure regulating devices and ordinary high-power transformer, high power industrial frequency test, resonant excitation and the capacity of power just test, making a systematic 1 / Q greatly reduce weight and volume for ordinary test device, general ***1/*0.
3. Improve output voltage waveform. Resonance power is resonant filter circuits, can improve output voltage waveform distortion, obtain good sine wave, prevent to try the harmonic peak breakdown products by mistake.
4. Prevent large short-circuit current burn breakdown. In the series resonant state, when try product insulation weakness is punctured, circuit loop current harmonic, immediately take off for normal test current rapid drop of 1 / Q. And parallel resonant or test transformer way when pressure test, breakdown current rise a few times, both immediately, compared with short-circuit current breakdown current differ hundreds times. So, can effective network (find weaknesses, again not exist insulation large short-circuit current burn breakdown disasters.
5. Won't appear any recovery overvoltage. Try product, because the breakdown occurred resonant conditions, high voltage loss also immediately disappear, arc instantly put out, and restore voltage is very long, establish the process again again reached very easily with flash winding, the former disconnect power supply voltage of voltage restoration process is a kind of energy accumulation of intermittent oscillation process, the process is long and recovery, won't appear any overvoltage.
