A study was conducted to estimate transient breakdown voltages (V/sub BD/s) between
contacts of a puffer-type SF/sub 6/gas circuit breaker. When contacts are opening …

Characteristics of the hot gas flow in an SF/sub 6/gas circuit breaker during short-circuit
interruption are investigated both experimentally and theoretically, to achieve a more …

The influence of low temperatures on the dielectric withstand and the breaking capacity of a
puffer-type SF/sub 6/circuit breaker was studied. Results of a dielectric and breaking tests …

A computer model for predicting the time evolution of the dielectric strength of SF/sub
6/following the interruption of a small capacitance current in a puffer-type circuit breaker is …

Using an experimental apparatus modeled for the contact portion of a gas insulated
switchgear (GIS), the influence of the distance between the portion and the dead tank of the …

電力用しゃ断器には, 様 々な源理方式のものがあるが, 大 容量器として最近発達の著しいのが
バッファ式の SF6 ガ スしゃ断器 (以 下バッファ式 GCB と 略す) である. 既に国内でも 550kV 50 kA …

The dielectric performance of the circuit breaker between poles after current interruption was
verified by testing. Test conditions based on IEC standards were examined. Based on these …

The purpose of the present paper is to show the dielectric characteristics of inhomogeneous
hot SF/sub 6/gas in a gas circuit breaker (GCB) experimentally. High-temperature and low …

SF/sub 6/is blown through the arc during interruption of an SF/sub 6/puffer circuit breaker.
This hot gas flows down an exhaust tube into the chamber of a dead tank circuit breaker …

The interrupting chamber for a 550 kV 1-break gas blast circuit breaker (GCB) is developed.
To cope with voltages and interrupting capacities of nearly double per break compared with …
