Abstract
The utility model provides a circuit breaker generating line structure with radiating effect, belongs to switch electrical apparatus technical field. Including connecting portion and transition portion, connecting portion be located the length direction's of transition portion both sides, its characterized in that: the air vent has been seted up in the transition portion. The advantage: neither consuming more copper products, saving the cost, simple structure is reliable moreover, and the cooling effect that makes the circuit breaker is showing and improves.
Description
Technical field
The utility model belongs to device for switching technical field, is specifically related to a kind of circuit breaker bus line structure with radiating effect.
Background technology
Omnipotent breaker is known circuit protection device also known as frame-type circuit breaker (hereinafter referred to as circuit breaker); the usual operating current because of long-time load kilo-ampere; larger heat can be produced again under current vortex and galvanic circle electrical impedance effect simultaneously, cause circuit breaker to have higher temperature rise.And higher temperature rise makes the operational environment of circuit breaker become severe, it is many unfavorable to bring, and as caused the bad pernicious situation such as the premature aging of insulating part, the accelerated oxidation of contact point, greatly have impact on the useful life of circuit breaker.Therefore, the temperature rise that how effectively can reduce circuit breaker becomes one of key technology of this area research.
In prior art, circuit breaker bus structure disclosed by Fig. 1, and breaker body 1 is connected with multiple circuit breaker buses 2 of electrical network, multiple circuit breaker buses 2 are positioned at the outgoing line side of breaker body 1.In order to reduce the temperature rise of circuit breaker, usually adopt the sectional area increasing galvanic circle to improve the radiating effect in loop, but this makes the consumption of copper material greatly improve, and the effect obtained is not very good yet.
In view of above-mentioned prior art, be necessary existing circuit breaker bus line structure rational modification in addition.For this reason, the applicant has done positive and useful design, and defines technical scheme described below.
Summary of the invention
The purpose of this utility model one will be provided neither to consume more copper material can ensure again simple and reliable for structure, and key effectively can also reduce the circuit breaker bus line structure with radiating effect of circuit breaker temperature rise.
The purpose of this utility model reaches like this, and a kind of circuit breaker bus line structure with radiating effect, comprise connecting portion and transition part, described connecting portion, in the both sides in transition length direction, transition part offers air vent hole.
In a specific embodiment of the present utility model, described air vent hole is vertical through holes through from top to bottom.
In another specific embodiment of the present utility model, described air vent hole is multiple, in array distribution between multiple air vent hole.
In another specific embodiment of the present utility model, the cross sectional shape of described air vent hole is strip.
In another specific embodiment of the present utility model, the cross sectional shape of described air vent hole is circular.
In an of the present utility model and then specific embodiment, the thickness of described transition part is greater than the thickness of connecting portion.
The utility model owing to offering multiple air vent hole on the transition part of circuit breaker bus, and air-flow in time to bus cooling, thus can effectively reduce the temperature rise of circuit breaker by described air vent hole.Said structure neither consumes more copper material, saves cost, and simple and reliable for structure, and the cooling-down effect of circuit breaker is significantly improved.

Embodiment
Applicant will describe in detail embodiment of the present utility model below by reference to the accompanying drawings; but applicant is not the restriction to technical scheme to the description of embodiment, any changing in the form rather than substance according to the utility model design all should be considered as protection range of the present utility model.
As shown in Figure 2, the utility model relates to a kind of circuit breaker bus line structure with radiating effect, multiple circuit breaker bus 2 is positioned at rear and the outgoing line side of breaker body 1, and one end of each circuit breaker bus 2 is electrically connected with circuit breaker internal bus, the other end is electrically connected with line busbar.Described breaker body 1 refers to circuit breaker itself.Concrete, described circuit breaker bus 2, according to circuit breaker three-phase or four phases, is divided into three groups or four groups.Often group is setting up and down two, if circuit breaker is three-phase, is then three groups totally six.If circuit breaker is four phases, then it is four groups totally eight.Each circuit breaker bus 2 respectively comprises connecting portion 21 and transition part 22, and connecting portion 21 is positioned at the both sides of transition part 22 length direction.Described connecting portion 21 is positioned at the both sides of transition part 22 length direction.Connecting portion 21 is for being electrically connected busbar.Common, the electrical connection of itself and other busbar is realized by offering connecting hole 211 on connecting portion 21.Namely on the corresponding busbar coordinated with connecting portion 21, also offer installing hole, and realize both electrical connections by trip bolt.Transition part 22 is the part between two connecting portions 21, for connecting two connecting portions 21, transition part 22 offers air vent hole 221.Preferably, air vent hole 221 is vertical through holes through from top to bottom, thus meets the flow direction of air-flow, is convenient to the heat radiation of circuit breaker bus.Described air vent hole 221 is multiple, and in array distribution between multiple air vent hole 221, air-flow can flow through from multiple air vent hole 221, strengthens the radiating effect of circuit breaker busbar.As Fig. 3, Fig. 4, for the profile of air vent hole 221, its shape is unrestricted, can be circular hole, also can be strip etc.Due to transition part 22 offering air vent hole 221, its current capacity obtains restriction, and in order to ensure current capacity, usual transition part 22 should do the suitable amplification on volume, and namely the thickness of transition part 22 is greater than the thickness of connecting portion 21.
