Variable Frequency Series Resonant Test Equipment

Tunable Frequency Industrial Power Frequency Series Resonant Voltage Withstand Device Product Introduction

As the power system evolves, the capacity of operating equipment has increased significantly, such as thermal power generation units, with individual unit capacities exceeding1000MWHydroelectric power generating units, with individual unit large capacity now reached800MWThese equipment's alternating current (AC) frequency withstand tests, if conducted with traditional testing equipment,(Power Frequency Test Transformer)Due to the large capacity required for the tests, the test transformers and voltage regulators are extremely heavy, and it's also challenging to find a large-capacity test power source on-site.Extreme.Inconvenient. The power frequency resonance device is suitable in terms of test power capacity, equipment weight, test waveform, and investment.Extreme.Significant Advantages.

TPXB-ESingle-phase power frequency series resonance voltage withstand equipment mainly targets single-machine capacity of250MWDesign and manufacturing of AC withstand voltage tests for below-hydro generators.

Product Features

1Due to resonant reactive power compensation, the power of the power supply and equipment is only the required capacity of the test item.1/10Below(1/Q10)Compact in size, lightweight, with high output capacity and a small power requirement, affordable, easy to operate, and safe to use.

2Series resonance is essentially an AC current filter circuit, which ensures that the current passing through the test item is predominantly the fundamental frequency current, with a low output voltage waveform distortion rate.(THD)Extreme.Small, superior to all existing types of communication pressure equipment

3Sample short-circuit current after flashover or breakdown is only a fraction of the test current before short-circuit.1/10The following(1/Q)Effectively prevents the expansion of damage to fault points after puncturing.

4Instant arc quenching upon flashover, followed by a prolonged process to establish voltage in the resonance state after arc quenching.(Seconds)It is a process of establishing a steady state, with no concern for voltage overshoot and no risk of recovery overvoltage from microsecond or millisecond transient processes.
