Abstract
Disclosed is an auxiliary switch with a magnetic blowout arc apparatus, comprising moving contacts, static contacts, insulating supports, a rotating shaft, a bearing, and an end portion pressure plate, wherein the insulating supports are arranged between the adjacent static contacts; and the contact/separation between the moving contacts and the static contacts are realized by operating the rotating shaft. The auxiliary switch of the utility model is characterized in that at least one of the insulating supports is provided with a cavity and the cavity is internally provided with a magnet used for attracting the arc generated the instant the moving contacts and the static contacts just separate or are about to contact. The auxiliary switch of the utility model can be used for turning-on and breaking the AC circuit and reliably breaking the DC high sensitive load circuit.
Description
Technical field
The utility model relates to a kind of auxiliary switch with magnetic quenching device.
Background technology
At present; Known auxiliary switch structure is made up of movable contact spring, static contact, insulating support, rotating shaft, bearing and end pressing plate; Realize the break-make of switch through the operation rotating shaft, be widely used in the operating mechanism combined floodgate, separating brake of high voltage switchgear, the usefulness of chain and signal controlling.But along with the increase of operating mechanism energy storage, the electric current of auxiliary switch disjunction dc inductance load is increasing.General auxiliary switch is the specified 3A direct current of disjunction inductive load electric current reliably, brings risk for the reliability of high voltage switchgear.
Summary of the invention
In order to overcome the deficiency of existing auxiliary switch disjunction dc inductance load capacity, the utility model provides a kind of disjunction alternating current circuit that can not only be used to connect, and the auxiliary switch with magnetic quenching device of the reliable high perceptual load circuit of disjunction direct current of ability.
The technical scheme that the utility model adopts is:
Auxiliary switch with magnetic quenching device; Comprise movable contact spring, static contact, insulating support, rotating shaft, bearing and end pressing plate; Be provided with insulating support between the adjacent described static contact; Realize the contact or the separation of described movable contact spring, static contact through the operation rotating shaft, it is characterized in that: at least one described insulating support is provided with cavity, is equipped with in the cavity to be used to attract described movable contact spring and static contact just to separate maybe the magnet of the electric arc that the moment with contact produces.
The part that the described static contact of the utility model stretches out insulating support is a binding post, can directly be connected with the plug bush type terminal.When switch motion; Movable contact spring has just separated maybe with the moment generation electric arc that contacts with static contact; The magnetic field that this electric arc produced receives the effect of magnet to produce crooked and is elongated and extinguishes rapidly; Thereby reduce the arcing time, protected contact and controlled the arcing direction, improved the ability of switch disjunction DC circuit.
The beneficial effect of the utility model is embodied in: simple in structure, disjunction direct current inductive load electric current reaches more than the 3A.

Embodiment
See figures.1.and.2; Auxiliary switch with magnetic quenching device; Comprise movable contact spring 7, static contact 6, insulating support 3, rotating shaft 1, bearing and end pressing plate 2; Be provided with insulating support 3 between the adjacent described static contact 6; Realize the contact or the separation of described movable contact spring 7, static contact 6 through operation rotating shaft 1, characteristics are that at least one described insulating support 3 is provided with cavity 5, are equipped with in the cavity 5 to be used to attract described movable contact spring 7 and static contact 6 just to separate maybe the magnet 4 of the electric arc that the moment with contact produces.
The part that the described static contact 6 of the utility model stretches out insulating support 3 is a binding post, can directly be connected with the plug bush type terminal.When switch motion; Movable contact spring 7 has just separated maybe with the moment generation electric arc that contacts with static contact 6; The magnetic field that this electric arc produced receives the effect of magnet to produce crooked and is elongated and extinguishes rapidly; Thereby reduce the arcing time, protected contact and controlled the arcing direction, improved the ability of switch disjunction DC circuit.
The described content of this specification embodiment only is enumerating the way of realization of inventive concept; Should not being regarded as of the protection range of the utility model only limits to the concrete form that embodiment states, the protection range of the utility model also reach in those skilled in the art conceive according to the present invention the equivalent technologies means that can expect.
