Abstract

In order to study the characteristics of VFTO waveform and influence of switch movement speed

a modeling method of high frequency spark is built

and MOA’s effect on VFTO amplitude is testified

a set of 252 k V GIS research platform is built. Firstly

the main circuit of the platform is designed

the device parameters are fixed.The length of conduct bars

the value of the coupling capacitance and the frequency range of VFTO/VFTC is calculated in simulation. Secondly

the shielding and triggering devices

as well as the VFTO

VFTC and contact distance measurement systems are designed. Finally

the platform is tested. The result shows that the platform can generate typical VFTO and VFTC waveforms

and the VFTO

VFTC a

nd contact distance are measured accurately.The speed of the disconnect switch can be adjusted among the rage of 0.02

.1 m/s and 0.7

.5 m/s.
