Problems solved by technology
[0005] The generation of arcs during the transition of the two contacts can lead to unwanted effects that negatively affect the operation of the circuit interrupter and even potentially lead to a safety hazard
These negative effects will also have adverse consequences on the operation of the circuit breaker, melting and evaporating the contact surface, burning out the insulating material, and causing fire, explosion and other dangers to the oil-filled equipment; Moving under heat can easily cause flashover and short circuit and hurt people or cause the expansion of accidents

The invention belongs to the technical field of circuit breakers, and in particular relates to a circuit breaker for distribution network automation, which includes a fixed plate, a vacuum shell, a drive motor, a limit mechanism, a drive sleeve, a first conductor rod, and a second conductor rod. The circuit breaker designs the relative swing of the first conductor rod and the second conductor rod, so that after the first conductor rod and the second conductor rod that transmit current are disconnected, the second contact installed on the first conductor rod that transmits current The distance between the first contact and the first contact installed on the second conductor rod becomes larger; the electric field intensity between the first contact and the second contact becomes smaller, the resistance becomes larger, and the arc is easily extinguished; and the design of the present invention The circuit breaker adopts double fractures in series, so that the total length of the arc is lengthened, and the resistance of the arc gap increases. Under the condition of the same contact stroke and opening speed, the speed at which the arc is elongated increases exponentially, which accelerates the arc gap resistance. Increase, improve the recovery speed of the meson intensity, and shorten the arc extinguishing time.
Description
[0001] Technical field [0002] The invention belongs to the technical field of circuit breakers, in particular to a circuit breaker for distribution network automation. Background technique [0003] A circuit interrupter is an electrical part that is used to open an electrical circuit, interrupting the flow of electricity. A basic example of a circuit interrupter is a switch. A switch basically consists of two electrical contacts that are in one of two states : Closed, meaning that the two contacts are in electrical contact with each other, allowing current to flow between the two contacts, or open, meaning that the two contacts are not in electrical contact with each other, preventing current flow. [0004] In high voltage applications, as the two contacts separate, an arc can form in the gap between the two contacts. An arc is a plasma discharge between two points caused by an electric current that ionizes a gas in the air between the two points. [0005] The generation o...
