Calculation of transient puffer pressure rise takes mechanical compression, nozzle ablation, and arc energy into consideration
YOSHIOKA YOSHIO, OOSAWA NAOKI
IEEE Transactions on Power Delivery   20(1) 143-148   Jan 2005   [Refereed]
Thermal puffer-type gas circuit breaker (GCB) has a high current interruption capability with low driving energy. In this paper, pressure rise, mass flow, and temperature calculations were carried out using a new calculation model, which takes mec...
Effect of puffer volume and operating force on dielectric recovery performance in thermal puffer-type gas circuit breaker
YOSHIOKA YOSHIO, OOSAWA NAOKI
IEEE Transactions on Power Delivery   20(3) 1897-1903   Jul 2005   [Refereed]
In order to investigate the influence of puffer volume and operating force to dielectric performance of GCB at current interruption, we calculated the prospective dielectric withstand voltage between arcing contacts. We could clarify that large in...
