mv CIRCUIT BREAKER gas Effect explain
2020/4/8Air circuit breakers use compressed air or gas to interrupt the arc. In air blast circuit breakers, compressed air stored in a tank is released through a nozzle at high velocity. During the operation of the breaker, the air valve connected between the compressed air tank and the arcing chamber will be opened, then the pressurized air enters into the arcing chamber.

70kV system Method
2017/12/1Scan timing was set as the peak timing in the true lumen of the descending aorta, which was determined by the timing bolus method in 70 kV CTA, and by the bolus tracking method in 120 kV CTA. This technical limitation meant that the ROI could not be moved simultaneously during acquisition of the time intensity curve in the ROI in the 192 section dual source CT scanner.
