Basic Info

Model NO.: 500KV/500KVA
HS Code: 903033200

Product Description

The device is mainly aimed at consumers 10kV, 110 kv cable, 220kV 35kV, 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 10kV 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.

500kv/500kVA Withstand Voltage Resonant Test Set

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 10-1/30.

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.

1.Device high accuracy.with, over-current, zero startup, system detuning (flash) protection function, treasure-the overpressure over-current protection value can according to the needs of user setting, try product flash when winding treasure-the protection movement and can flash, flash winding down for the test voltage value are analyzed.

2.The whole device, the largest piece very light weight not more than 40kg and convenient for field use.

3.Device has three working mode, user-friendly according to the site condition flexible choice, improve test speed. Working mode for: automatic mode and manual mode, automatic tuning manual pressurization mode.

4.Different print data can be stored and the data Numbers is, stock, easy to help users digital identification and searching.

5.Device automatic frequency sweep frequency starting point when in the specified scope set arbitrary, sweep frequency direction can choose, while upward and downward LCD big screen display scanning curve, be convenient for the user intuitive understanding whether find resonant point.

6.Adopted DSP platform technology, can conveniently according to the needs of user increase or decrease function and upgrade, but also makes the man-computer exchange interface humanized.

User's Requirement: 
1.220KV GIS Breaker,Cable,transformer or other apparatus
2.Capacitance of DUT 0.005uF;
3.Test Voltage of 500KV;
4.Test Frequency:20-300Hz
