Abstract
The utility model discloses a bipolar vacuum circuit breaker for a gas-insulated metal-enclosed switching device, which comprises a framework. The framework is connected with a fixing plate, a spring operating mechanism is arranged in the framework and is connected with a main shaft through a transmission mechanism, the two ends of the main shaft are arranged on the framework, the main shaft is connected with a bellows component through a connecting rod I on the bellows component, the bellows component is connected with an insulation pull rod, the insulation pull rod is connected with two vacuum arc-extinguishing chambers, and the two vacuum arc-extinguishing chambers are arranged in an insulation tube and are arranged horizontally. The bipolar vacuum circuit breaker has small size, and the switching device has stable performance. The bipolar vacuum circuit breaker is suitable for the 50Hz switching device of a traction power system of an electrical railway locomotive with the voltage rating being 2 multiplied by 27.5kV, and can be frequently operated or can cut off short-circuit current for multiple times within the operating current range. Therefore, the bipolar vacuum circuit breaker is applicable to re-closing, and the working life of the bipolar vacuum circuit breaker can reach 10,000 times.
Description
Technical field
The utility model relates to a kind of circuit breaker, relates in particular to a kind of vacuum circuit-breaker that is used on the electric railway power transmission and distribution system switching equipment.
Background technology
Box stationary gas insulated metal sealing switch equipment (C-GIS) is a circuit devcie commonly used in the modernized electrical power trans mission/distribution system, often uses in the power transmission and transformation system of electric pressure 10kV～40.5kV.The circuit breaker that uses in the present this switchgear is mainly three-pole breaker, and can not be applied in electric pressure is in the electric railway locomotive traction electric power system of 2 * 27.5kV.Though domestic have indivedual double-pole cut-outs, its vacuum interrupter is and is arranged vertically, and structural configuration is compact and reasonable not, causes switchgear unstable properties and profile excessive.
The utility model content
The purpose of this utility model provides a kind of bipolar vacuum circuit-breaker that is used on the Cubicle Gas-Insulated Switchgear, and applicable electric pressure is 2 * 27.5kV.
The technical solution of the utility model realizes in the following manner:
A kind of bipolar vacuum circuit-breaker that is used on the Cubicle Gas-Insulated Switchgear, comprise framework, framework links to each other with fixed head, be provided with spring operating mechanism in the framework, spring operating mechanism links to each other with main shaft by transmission mechanism, the main shaft two ends are arranged on the framework, main shaft links to each other with bellows component by the connecting rod I on the bellows component, bellows component links to each other with insulated tension pole, insulated tension pole links to each other with vacuum interrupter, vacuum interrupter is arranged in the insulating cylinder, and described vacuum interrupter is two, two vacuum interrupter horizontal arrangement.
Above-mentioned transmission mechanism comprises the connecting lever on connecting rod II and the main shaft, and connecting rod II one end links to each other with the output toggle arm of spring operating mechanism, and the other end links to each other with main shaft by the connecting lever on the main shaft.
Two vacuum interrupter horizontal arrangement in the utility model, compared with prior art, its bodily form is less.In addition, spring operating mechanism drives two vacuum interrupters by transmission mechanism and moves the switchgear stable performance simultaneously.The utility model is applicable to that electric pressure is the switchgear of electric railway locomotive traction electric power system of the 50Hz of 2 * 27.5kV, in current margin, can carry out frequent operation or repeatedly cut-off short circuit current, be applicable to reclosing operation, working life can reach 10000 times.
Description of drawings
