Abstract
The utility model discloses a contactor outer cover with an electric arc-extinguishing function. The contactor outer cover with the electric arc-extinguishing function comprises a housing, wherein rectangular grooves are formed in the sidewalls of the left side and the right side of the housing respectively; a plurality of clapboards made from an insulating material are arranged in the rectangular grooves; and a long groove is formed in the vertical side of each clapboard and towards the interior of the clapboard. According to the contactor outer cover with the electric arc-extinguishing function disclosed by the utility model, the plurality of clapboards are manufactured from the insulating material to realize arc extinguishing by cutting off the arc route of an electric arc, thus achieving the purpose of arc extinguishing.
Description
Technical field
The utility model relates to the electric equipment field, is specifically the go out contactor enclosing cover of electric arc of a kind of band.
Background technology
Contactor is the electrical equipment that switches on and off continually at a distance alternating current-direct current main circuit and large volume controlled electric current.Has the large use safe ready of the control of being swift in motion capacity, the advantages such as energy frequent operation and remote operation.Main master switch as motor; Small generator; Electroheat equipment; The master switch of the various devices such as electric welding machine and capacitor group.Can switch on and off load current, but can not cutting-off of short-circuit electric current, therefore normal and fuse and thermal relay etc. are used in conjunction with.Mainly by contact system; The composition such as electromagnetic mechanism and arc-control device.Coil and fixed contact are fixed, and after coil electricity, the electromagnetic force of generation overcomes the reaction force of spring, with the armature adhesive and make; The fixed contact contact, thus main circuit connected.When coil blackout, because electromagnetic attraction disappears, armature relies on the reaction force of spring and tripping, and moving contact also separates with fixed contact thereupon, the cut-out main circuit.
And the arcing phenomenon easily occurs in contactor in normal work, when contactor disconnects, the arcing that forms between the contact lonely shape between connection two contact often.
The utility model content
The purpose of this utility model is to provide the go out contactor enclosing cover of electric arc of a kind of band, the problem that exists to solve prior art.
In order to achieve the above object, the technical scheme that adopts of the utility model is:
The go out contactor enclosing cover of electric arc of a kind of band, include shell, it is characterized in that: shell left and right side top side wall is respectively equipped with rectangular channel in shell, be close to respectively rectangular channel bottom in rectangular channel, the sidepiece cell wall vertically is provided with the dividing plate that the multiple tracks insulating material is made, the multiple tracks dividing plate is parallel each other, and the vertical side of each dividing plate has elongated slot respectively in dividing plate.
The go out contactor enclosing cover of electric arc of described a kind of band, it is characterized in that: each dividing plate top is respectively equipped with groove.
The contactor enclosing cover that the utility model provides a kind of band to go out electric arc, utilize insulating material to make the multiple tracks dividing plate, carrys out arc extinguishing with the curved line that cuts off electric arc, thereby reach the purpose of arc extinguishing.
Description of drawings
Fig. 1 is the utility model three-dimensional structure schematic diagram.
