Abstract
The utility model discloses an arc extinguishing increases magnetism device, include the base and locate the multiunit explosion chamber in the base, every group be equipped with apron, characterized by on the explosion chamber: every group both sides inner wall all is equipped with vertical magnetic conduction board around the explosion chamber, two vertical magnetic conduction board upper end is equipped with horizontal magnetic conduction board. The utility model provides an arc extinguishing increases magnetism device changes the U type frame of background art into two vertical magnetic conduction boards and a slice horizontal magnetic conduction board, during the assembly earlier with two vertical magnetic conduction boards put into the open slot, then with horizontal magnetic conduction board put into the recess in, last cover the apron can, the assembly is more convenient and the structure is more stable.
Description
Technical Field
The utility model relates to a low-voltage apparatus field, concretely relates to arc extinguishing increases magnetic device.
Background
At present, the arc control device that provides in the market generally includes the base and locates the multiunit explosion chamber in the base, is equipped with the apron on every group explosion chamber, is equipped with U type frame in the explosion chamber, and this kind of arc control device is during the difficult accurate explosion chamber that inserts of U type frame when the installation for assembly process is loaded down with trivial details.
Disclosure of Invention
In view of the deficiency of the background art, the utility model aims to solve the technical problem that an arc extinguishing that assembles more conveniently and the structure is more stable increases magnetism device is provided.
Therefore, the utility model discloses an adopt following technical scheme to realize:
the utility model provides an arc extinguishing increases magnetic device, includes the base and locates the multiunit explosion chamber in the base, every group be equipped with apron, characterized by on the explosion chamber: every group both sides inner wall all is equipped with vertical magnetic conduction board around the explosion chamber, two vertical magnetic conduction board upper end is equipped with horizontal magnetic conduction board.
Furthermore, the inner walls of the front side and the rear side of each group of arc extinguish chambers are provided with open grooves for accommodating the vertical magnetic conduction plates.
Furthermore, the bottom surface of the cover plate is provided with a groove for placing the transverse magnetic conduction plate.
After the technical scheme is adopted, the U-shaped frame in the background art is changed into the two vertical magnetic conduction plates and the one transverse magnetic conduction plate, the two vertical magnetic conduction plates are firstly placed into the open slot during assembly, then the transverse magnetic conduction plate is placed into the groove, and finally the cover plate is covered, so that the assembly is more convenient and the structure is more stable.

fig. 1 is a top view of the present invention;
FIG. 2 is a sectional view taken along line A-A of FIG. 1;
FIG. 3 is a schematic perspective view of the present invention with the cover plate removed;
fig. 4 is a schematic view of the three-dimensional structure of the middle vertical magnetic conductive plate and the horizontal magnetic conductive plate of the present invention.
Reference numerals: 1. a base; 2. an arc extinguishing chamber; 3. a cover plate; 4. a vertical magnetic conductive plate; 5. a transverse flux guide plate; 6. an open slot; 7. and (4) a groove.
Detailed Description
Referring to the above drawings, the utility model provides a pair of arc extinguishing magnetism increasing device includes base 1 and locates multiunit explosion chamber 2 in the base 1, every group be equipped with apron 3, characterized by on the explosion chamber 2: every group both sides inner wall all is equipped with vertical magnetic conduction board 4 around the explosion chamber 2, two 4 upper ends of vertical magnetic conduction board are equipped with horizontal magnetic conduction board 5, every group 2 both sides inner wall all is equipped with the open slot 6 that holds vertical magnetic conduction board 4 and put into around the explosion chamber, 3 bottom surfaces of apron are equipped with the recess 7 that holds horizontal magnetic conduction board 5 and put into.
In this embodiment, change the U type frame of background art into two vertical magnetic conduction plates 4 and a horizontal magnetic conduction plate 5, during the assembly earlier put into open slot 6 with two vertical magnetic conduction plates 4, then with horizontal magnetic conduction plate 5 put into recess 7, cover last apron 3 can, it is more convenient and the structure is more stable to assemble.
Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications and variations can be made in the embodiments or in part of the technical features of the embodiments without departing from the spirit and the scope of the invention.
