Abstract
A single-fracture can-type vacuum circuit breaker overcomes the defects that in the prior art, an existing vacuum circuit breaker is complex in structure, large in size, poor in heat dissipation performance and high in manufacturing cost. The single-fracture can-type vacuum circuit breaker is characterized in that a steel can, a left supporting insulator and a right supporting insulator form a vacuum chamber, a left sleeve, a bend-type left can and the left supporting insulator form a left wiring chamber, a right sleeve, a bend-type right can and the right supporting insulator form a right wiring chamber, the axis of a movable electric conductor is perpendicular to the axis of the steel can, the movable electric conductor penetrates through an electric conduction sleeve and form a single fracture with a fixed electric conductor, and clean and dry compressed air or other gas is filled into the left wiring chamber and the right wiring chamber to serve as an insulating medium or be used for keeping a vacuum state. The single-fracture can-type vacuum circuit breaker has the advantages that the structure is simple and compact, due to the fact that the movable electric conductor is directly and perpendicularly arranged in the vacuum chamber and the influence of the gravity on a movable electric conductor contact terminal is eliminated, the coaxiality of the movable electric contactor contact terminal and a fixed electric conductor contact terminal can be guaranteed, and due to the fact that an arc extinguish chamber porcelain bushing is omitted, the heat dissipation performance is good and the manufacturing cost of an arc extinguish chamber and the manufacturing cost of the vacuum circuit breaker are reduced.
