Abstract
The utility model relates to a two-pole circuit breaker with a N pole, comprising an upper cover, a magnetic yoke, a coil, an iron core, an arc extinction chamber, a middle cover, a N pole, a wire-outlet post, a N pole arc-leading device, and a base, wherein an arc-striking sheet of the N pole arch-striking device extends towards the front end of a static contactor base and forms an arch included angle with the front end of the static contactor base, and an arc-outlet hole of the arc-striking device is arranged at one side of the wire inlet end, and the three positions of the arc-striking sheet, the arc-outlet hole, and the static contactor base are engaged, which are led out from a movable contactor once electric arc appears in the N pole when the circuit is broken, and the effect of protecting the movable contactor is relatively excellent.
Description
Technical field
The utility model relates to a kind of circuit breaker, relates in particular to a kind of two utmost point circuit breakers with the N utmost point.
Background technology
As shown in Figure 1; two utmost point circuit breakers of the existing band N utmost point by loam cake, yoke, coil, iron core, arc control device, middle cover, the N utmost point connect, parts such as outlet column, N utmost point arc-initiating device, pedestal form; wherein the striking sheet material of N utmost point arc-initiating device is a fine copper; simultaneously; its version is unfavorable for striking, and is relatively poor to the protection effect of contact.
Summary of the invention
The purpose of this utility model is at the deficiencies in the prior art, and a kind of two utmost point circuit breakers of the band N utmost point of N utmost point striking better effects if are provided.
For achieving the above object, the utility model adopts a kind of two utmost point circuit breakers with the N utmost point, comprise that loam cake, yoke, coil, iron core, arc control device, middle cover, the N utmost point connect, outlet column, N utmost point arc-initiating device, pedestal, the striking sheet of N utmost point arc-initiating device extends to front end one side of stationary contact headstock, and form an arc angle with the front end of stationary contact headstock, the arc hole that goes out of N utmost point arc-initiating device is arranged on end of incoming cables one side, and striking sheet, the front end three position that goes out arc hole and stationary contact headstock are suitable.
The stationary contact headstock that the utility model further is set to the N utmost point vertically prolongs, and front end has the formation arc transition.
The utility model provides a kind of two utmost point circuit breakers with the N utmost point, and striking sheet, the front end three position that goes out arc hole and stationary contact headstock are suitable, when opening circuit disjunction, in case electric arc appears in the N utmost point, are drawn away from moving contact by very fast, and protection moving contact effect is better.
Description of drawings
Fig. 1 is the utility model background technology structural representation.
Fig. 2 is the N electrode structure schematic diagram after the utility model embodiment removes middle cover.
Embodiment
As shown in Figure 2, specific embodiment of the utility model is a kind of two utmost point circuit breakers with the N utmost point, comprise that loam cake, yoke, coil, iron core, arc control device, middle cover, the N utmost point connect, outlet column, N utmost point arc-initiating device, pedestal 1, the stationary contact headstock 3 of the N utmost point vertically prolongs, and its front end 31 has the formation arc transition.The striking sheet 2 of N utmost point arc-initiating device extends to front end 31 1 sides of stationary contact headstock 3, and form an arc angle with the front end 31 of stationary contact headstock 3, the arc hole 4 that goes out of N utmost point arc-initiating device is arranged on end of incoming cables one side, and striking sheet 2, the front end 31 three positions that go out arc hole 4 and stationary contact headstock 3 are suitable.
The material of the striking sheet 2 in the foregoing description is an iron.
Striking sheet 2 of the present utility model, the front end 31 three positions that go out arc hole 4 and stationary contact headstock 3 are suitable, when opening circuit disjunction, in case electric arc appears in the N utmost point, are drawn away from moving contact 5 by very fast, and protection moving contact 5 effects are better.
