Abstract
The invention discloses an arc extinguish chamber applied to a breaker. The arc extinguish chamber comprises an inner cavity; the inner cavity is a closed space; a fixed contact, a pull rod and an arc contact are arranged inside the inner cavity; one end of the fixed contact is connected with an external circuit and the other end of the fixed contact can be sequentially inserted into a secondary arc extinguish chamber and a primary arc extinguish chamber; the pull rod can do vertical motion; and the arc contact is positioned at the top end of the pull rod and in the primary arc extinguish chamber and can be tightly attached to the fixed contact by means of elastic force of the arc contact. In the brake separating process of the arc extinguish chamber applied to the breaker, the arc generated by the arc contact during switching off is mainly limited in the primary arc extinguish chamber, and arc extinguishing can be further performed by the secondary arc extinguish chamber even though part of the arc flows out of the primary arc extinguish chamber. The arc extinguishing effect can be further improved by using arc extinguishing gas inside the arc extinguish chamber.
Description
Technical field
The present invention relates to a kind of arc control device that are applied in circuit breaker, particularly relate to a kind of arc control device in circuit breaker that are applied to dual arc-suppression function.
Background technology
The electric arc that arc control device produce while disconnection in order to limiting circuit breaker, also can play the effect of auxiliary extinction of arc sometimes.With regard to principle, the basic reason that circuit breaker produces electric arc is to contain a large amount of free electronics in device for switching contact itself and contact medium around, in the time that arcing contact disconnects, if there is enough large voltage between contact, and circuital current is while also reaching your pupil's arc current, will encourage above-mentioned free electronics and form electric arc.The electric arc of above-mentioned formation not only has very large destruction to contact, and to make the time lengthening of open circuit, even more serious situation be to cause security incident because of electric arc.In sum, need to design a kind of arc control device in circuit breaker that are applied to higher reliability.
Summary of the invention
Technical problem to be solved by this invention is, a kind of arc control device that are applied in circuit breaker are provided, and its electric arc producing while utilizing dual arc extinguishing structure to disconnect the arcing contact in circuit breaker carries out arc extinguishing, has improved the reliability of arc extinguishing.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of arc control device that are applied in circuit breaker, these arc control device comprise: inner chamber, this inner chamber is confined space, this inner chamber inside comprises: fixed contact, this fixed contact one end connects external circuit, and the other end can insert among double arc control device and heavy arc control device, within described one heavy arc control device (14) are nested in described double arc control device (15) successively; Pull bar, this pull bar can be for vertical movement; And arcing contact, this arcing contact is positioned at described pull bar top, and this arcing contact is positioned among heavy arc control device, and it can utilize self elastic force and described fixed contact to fit tightly; Described inner chamber, heavy arc control device and double arc control device inside are all filled with arc extinguishing gases.
Described is applied in the arc control device in circuit breaker, at least has two contacts between described arcing contact and fixed contact while contact.
Described is applied in the arc control device in circuit breaker, and described one heavy arc control device and double arc control device are seal cavity.
Advantage of the present invention is, the arc control device that the present invention is applied in circuit breaker have i.e. heavy arc control device and the double arc control device of dual arc extinguishing structure, these heavy arc control device and double arc control device are seal cavity, and the arcing contact in circuit breaker is positioned among heavy arc control device simultaneously.In separating brake process, the electric arc that arcing contact produces while disconnection is mainly limited among heavy arc control device, even if there is part electric arc to flow to outside heavy arc control device, still can implement further arc extinguishing by double arc control device.In addition, can also strengthen arc quenching effect by the arc extinguishing gases of arc control device inside.
Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram that the present invention is applied to the arc control device in circuit breaker.
Embodiment
For further disclosing technical scheme of the present invention, be hereby described with reference to the accompanying drawings embodiments of the present invention:
The present invention is applied to arc control device in circuit breaker and is adopting on the basis of dual arc-control device, is combined in the mode that is filled with arc extinguishing gases in the seal chamber of arc control device inside, and the electric arc producing when the arcing contact in circuit breaker is disconnected carries out reliable arc extinguishing.
In order to realize above-mentioned design, the present invention can adopt following execution mode:
Fig. 1 is the overall structure schematic diagram that the present invention is applied to the arc control device in circuit breaker, in figure, comprise: inner chamber 12, this inner chamber 12 is for being positioned at the confined space of these arc control device 10 inside, these inner chamber 12 inside comprise: fixed contact 11, these fixed contact 11 one end connect external circuit, and the other end can insert among double arc control device 15 and heavy arc control device 14 successively; Pull bar 13, this pull bar 13 can be for vertical movement; Arcing contact 131, this arcing contact 131 is positioned at described pull bar 13 tops, this arcing contact 131 is positioned among heavy arc control device 14, and it can utilize self elastic force and described fixed contact 11 to fit tightly, and at least has two contacts between this arcing contact 131 and fixed contact 11 while laminating; Wherein, described inner chamber 12, heavy arc control device 14 and double arc control device 15 inside are all filled with arc extinguishing gases, such as sulphur hexafluoride.
Further, described heavy arc control device 14 and double arc control device 15 are also made seal cavity, can further strengthen arc quenching effect.
Action situation while work below in conjunction with accompanying drawing explanation the present invention:
In the time pulling pull bar 13 to drive arcing contact in circuit breaker 131 and fixed contact 11 to disconnect, can produce electric arc, now, because heavy arc control device 14 and double arc control device 15 are seal cavity, therefore above-mentioned produced electric arc is limited among above-mentioned heavy arc control device 14 and double arc control device 15.In addition, described inner chamber 12, heavy arc control device 14 and double arc control device 15 inside are all filled with arc extinguishing gases, can further improve arc quenching effect.
More than, by description of listed embodiment, the basic ideas and basic principles of the present invention are set forth.But the present invention is never limited to above-mentioned listed execution mode, every equivalent variations of doing based on technical scheme of the present invention, improvement and deliberately become of inferior quality behavior, all should belong to protection scope of the present invention.
