Very Fast Transient Overvoltages (VFTO) might result in insulation failures inside or outside Gas Insulated Switchgears (GIS), and most of them are led to by the spacer flashovers in the light of operational experiences. To get a better understanding of the discharge process, an experimental study on spacer flashovers under nanosecond-pulses in compressed Sulphur Hexafluoride (SF6) gases is presented...
Based on the platform of laser-triggered surface flashover in pulsed voltage, experiment of laser-triggered surface flashover is carried out in air and vacuum condition with pulsed voltage. A single/double harmonic, with wavelength l of 1064/532 nm, Q-switched Nd: YAG laser is applied to trigger the surface flashover. The test system consists of flat electrodes and columned insulator. The material...
Based on the platform of laser-triggered surface flashover in pulsed voltage, experiment of laser-triggered surface flashover is carried out in vacuum condition with pulsed voltage. A single/double harmonic, with wavelength ?? of 1064/532 nm, Q-switched Nd:YAG laser is applied to trigger the surface flashover. The synchronization problem of laser pulse and voltage pulse is solved using a self-made...
High gradient insulating technology is one of the key technologies in new type dielectric wall accelerator. Micro-stacked insulators were prepared and preliminary experiment was done in this paper. Using high temperature laminated method, two types of micro-stacked insulators were designed and fabricated. The first was fabricated from interleaved layers of brass and polyimide (PI), and the other was...
In order to satisfy application demand for high performance and miniaturization of pulsed power system, multilayer high gradient insulators (HGI) were designed and fabricated. Using high temperature laminated method; we developed two types of HGI which were fabricated from interleaved layers of brass and polyimide (PI), stainless steel and fluorinated ethylene propylene (FEP). Small samples and large...
Experiment platform of laser-triggered surface flashover is set up, and the delay time and jitter of surface flashover switch are measured, respectively. The circuit model of surface flashover switch is set up. The simulation of the circuit by the formula, and the simulation waveform and the experiment waveform are consistent almost.
