Dead Tank Circuit Breakers — 72.5–800kV Technology lnner Construction of Interrupter Inner Construction of Interrupter 1. Interrupter The figure below shows the principle construction of the interrupter. The pressure of the gas in the puffer cylinder goes up when the gas is compressed by opening movement of the puffer cylinder. Fixed main contact Fixed arcing contact Moving main contact This pressurized and compressed gas goes to the arc between the stationary contact and moving contact. The nozzle concentrates the gas flow to the arc for efficient cooling. Trip spring Trip spring Arc...
