Dead Tank Circuit Breakers — 72.5–800kV The LW13A/23-363, LW13A-550, and LW13-800 family of products represent the technology platform for the highest kV rated XD|GE dead tank breakers. Single interrupting units per pole are utilized on breaker products from 363kV to 550kV without parallel capacitors and pre-insertion resistors. In addition, double interrupting unit designs are used for products from 363kV up to 800kV. Parallel capacitors and pre-insertion resistors are incorporated when double interrupting units per pole are used. Breakers from 363kV to 800kV can carry continuous current up...

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 Ratchet...
