Embodiment Construction

[0027] Specific embodiments of the present invention will now be described with reference to the accompanying drawings.

[0028] First, refer to the attached figure 2 with 3 , to describe the static contact used in the circuit breaker using the magnetic blowing action to extinguish the arc according to the first embodiment of the present invention. The static contact 11 of the first embodiment of the present invention includes a static contact 12 and an integrally formed body portion 13. The body portion 13 includes a static contact bearing portion 14 for carrying the static contact 12 and a wiring portion for introducing current. 15, and a bent portion 16 for connecting the static contact bearing portion 14 and the wiring portion 15, the static contact bearing portion 14 has a first end 14-1 connected to the bent portion 16 and an opposite second end 14- 2. The static contact 12 is located between the first end 14-1 and the second end 14-2 of the static contact bearing par...

Abstract

The invention discloses a fixed contact and a circuit breaker with the same. The fixed contact is used for the circuit breaker extinguishing arc by magnetic blow-out. The circuit breaker comprises the fixed contact and an integrated body. The body comprises a fixed contact carrier for bearing the fixed contact, a junction part for guiding in current, and a bent part for connecting the fixed contact carrier and the junction part. The fixed contact carrier is provided with a first end connected with the bent part and a reverse second end. The fixed contact is located between the first and second ends of the fixed contact carrier. The fixed contact carrier is provided with a cutoff segment along the extension direction of the fixed contact carrier. When current flows through the cutoff segment, the density of the current near the contact increases so that magnetic blow-out force near the contact increases. Therefore, arc can be blown out by larger magnetic blow-out force. Combustion time of the arc on the fixed contact is shortened, the fixed contact is protected, and the service life of the fixed contact is prolonged.

Description

technical field [0001] The invention relates to a static contact, which is used in a circuit breaker which uses magnetic blowing to extinguish arcs, and also relates to a circuit breaker with the static contact. Background technique [0002] Plastic Case Circuit Breaker (MCCB) is a circuit breaker that uses magnetic blowing to extinguish the arc. It is widely used in power distribution systems. The degree of damage to electrical equipment and the switch itself is reduced. Plastic case circuit breakers generally include a plastic case, a contact system, an arc extinguishing system, an operating mechanism and a release. When the short-circuit current occurs, the release device of the circuit breaker will trip instantaneously to make the operating mechanism act, and the moving contact and the static contact will be separated under the drive of the operating mechanism and the action of electric repulsion. When the moving contact is separated from the static contact, an arc wil...
