Abstract Multi-chamber fast arc extinguishing device has the advantages of fast response speed, good arc extinguishing performance, and can effectively suppress the line tripping caused by lightning impulse flashover. However, the process of stable conversion of impact discharge arc into power frequency follow current in the device is not clear, there is lack of in-depth research on the power frequency arc-establishing rate of the device, which limits further optimal design of the device. In response to the above issues, a lightning impulse combined with 10 kV power frequency voltage test platform was built. The process of stable conversion of impulse discharge arc into power frequency follow current was explored, a comparative analysis of the arc-establishing rate of an ordinary gap versus a semienclosed chamber gap was carried out. The influence of structural parameters and electrode radius on the arc-establishing rate of semienclosed chamber was analyzed, and further exploring the inhibition effect of breaking arc of multi-chamber arc extinguishing structure on arc-establishing rate.
The test platform consists of AC power supply, impact power supply, measurement equipment and corresponding protection components. During the test, the power frequency voltage is first applied to both ends of the specimen, then the capacitors are charged in parallel in a rectified fashion and the ignition gap breakdown, and lightning impact voltage is superimposed on both ends of the specimen. The specimen breakdown and flows an impact discharge current with amplitude of 1.8 kA and waveform of 12/25 µs, adopting a current transformer with a bandwidth of 160 Hz~4 MHz to capture arc current waveforms, and the arc current is used as trigger signal for the oscilloscope to realize the synchronous measurement of the superimposed voltage signal and the power frequency follow current signal.
The voltage and current waveforms after impulse breakdown in the semienclosed chamber show that when the air blowing effect of the semienclosed chamber can effectively accelerate the energy dissipation of the power frequency follow current, the arc can be extinguished within the first frequency half-cycle. The difference in arc-establishing rate between ordinary gap structures and semienclosed chamber gap structures is more than twice, and the air blowing effect of the semienclosed chamber can effectively reduce the arc-establishing rate. Limiting the movement speed of post-arc gas and increasing the airflow at the outlet of the chamber, which can reduce arc-establishing rate. Reducing the electrode radius enhances the self-magnetic compression effect of the arc and reduces the arc-establishing rate. Increasing the number of chambers effectively inhibits the injection of power frequency energy into the arc channel, limiting the arc-establishing rate to a very low level.
The following conclusions can be drawn from the analysis of the results: (1) The semienclosed chamber promotes the energy dissipation of the power frequency follow current and inhibits the establishment of power frequency follow current through the rapid air blowing effect, thus realizing the reduction of power frequency arc-establishing rate of the semienclosed chamber. (2) By changing the structural parameters of the chamber to regulate the movement speed of the post-arc gas, which can prevent the blockage of high-temperature gas in the chamber, reducing the arc-establishing rate. The magnetic field distribution of the discharge gap is regulated by reducing the electrode radius, which can effectively inhibit the development of the arc column diameter and reduce the arc-establishing rate. (3) Multi-chamber arc extinguishing structure by truncating the arc into multiple short arc segments to increase the arc pressure during the arc combustion, reducing the injected power frequency energy, which can inhibit the establishment of power frequency arc.
