    Abstract: DISCLOSED A METHOD OF APPLYING AN AMORPHOUS FUSED SILICA COATING TO A SUBSTRATE OF REFRACTORY NON-METALLIC MATERIAL. HIGH TEMPERATURE ARC PLASMA FROM AN ARC PLSMA SPRAY GUN IS PROJECTED ONTO THE SUBSTRATE SURFACE; AND PARTICLES OF A MATERIAL CONSISTING ESSENTIALLY OF CRYSTALLINE SILICA ARE FED INTO THE PLASMA, WHERE THEY ARE MELTED AND ENTRAINED IN THE PLASMA. THE GUN IS HELD CLOSE ENOUGH TO THE SUBSTRATE TO EFFECT MELTING OF THE SURFACE OF THE SUBSTRATE, OR THE PREVIOUSLY-APPLIED MATERIAL, IN THE REGION WHERE THE MOLTEN DROPS OF SILICA ENTRAINED IN THE PLASMA ARE IMPINGING AGAINST SAID SURFACE.

    Abstract: The present disclosure relates to a circuit breaker of a gas-insulated switchgear, and more particularly, to a self-blast circuit breaker of a gas-insulated switchgear, which reuses arc heat. A self-blast circuit breaker having a heat expansion chamber and a puffer chamber includes auxiliary intake valves which introduce a hot gas exhausted through an inside of an actuating rod, into the heat expansion chamber.

    Abstract: An arc chute for an electric circuit breaker comprises insulating sidewalls and plates, or fins, of insulating material that extend transversely of the sidewalls and have edges for engaging the arc as it moves into the chute. The sidewalls and edges of the plates are coated with a plasma-arc-sprayed refractory metal-oxide consisting essentially of amorphous fused silica.
