Abstract
The utility model relates to a power electrical product, in particular to a thermo-stable breaker arc deflecting cover. The arc deflecting cover inserts a solid rectangular sintered from ceramic into a rectangular metal grating slice with a V-shaped opening, while compared with prior art as the multilayer rectangle iron sheet structure with side border and bottom border fixed by red steel paper, with V-shaped opening, the utility model has better thermal insulation ability, longer service life and better durability.
Description
Technical field
The utility model relates to a kind of power electronic product, the parts on especially a kind of circuit breaker.
Background technology
The critical piece of grid sheet arc-control device is an arc extinguishing grid pieces.Arc-chute is installed in the arc control device of contact top, to each other mutually insulated.When the contact disjunction, after the electric arc of generation enters the grid sheet, be divided into the short arc of several sections series connection, and each grid sheet has become the electrode of these short arcs.Like this, the dielectric strength of 150-250V is arranged all between the electrode that every pair is made up of arc extinguishing grid pieces, the dielectric strength of whole arc-chute is increased greatly, the grid sheet can also absorb the electric arc heat simultaneously, causes electric arc to extinguish rapidly.
Present arc-extinguish chamber adopts the rectangle iron plate of sandwich tape V-arrangement opening, and iron plate side and base are fixed with red steel paper, through the electric current above 600 amperes the time, just causes the red steel paper burning easily, causes product to fall apart, and safety in production is caused danger.
Summary of the invention
The purpose of this utility model is for a kind of arc-extinguish chamber of nonflammable comparison safety is provided.
For realizing the purpose of this utility model, this specification provides a kind of high temperature resistant breaker arc extinguishing cover, comprises support section and grid sheet.Support section is the solid cuboid that ceramic roasting forms, and it is the opening of V-arrangement that the cross section is wherein arranged on the end face, and aperture position has the groove of some and parallel sided, and the support section bottom surface has two rankings to put the through hole that staggers.The grid sheet is the rectangular metal sheet of band V-arrangement opening, replaces the part rib of the groove on the support section, inlays to connect or cohere on support section.
This arc-extinguish chamber adopts pottery and sheet metal composite construction, than red steel paper of the prior art and iron plate composite construction heatproof more, and longer service life, more durable.
The purpose of this utility model, feature and advantage will be in conjunction with the embodiments, are further described with reference to accompanying drawing.
Description of drawings
Fig. 1 is prior art constructions figure;
Fig. 2 is a structure chart of the present utility model;
Wherein: 1 is support section, and 2 is the grid sheet, and 3 is red steel paper, and 4 is iron plate.
Embodiment
With reference to last figure, provide following embodiment.To help to understand the utility model by embodiment, but not limit content of the present utility model.All distortion that those of ordinary skill in the art can directly derive or associate from the disclosed content of the utility model all should be thought protection range of the present utility model.
This high temperature resistant breaker arc extinguishing cover comprises support section 1 and grid sheet 2.The solid cuboid that support section 1 forms for ceramic roasting, it is the opening of V-arrangement that the cross section is wherein arranged on the end face, and aperture position has the groove of some and parallel sided, and support section 1 bottom surface has two rankings to put the through hole that staggers.Grid sheet 2 is the rectangular metal sheet of band V-arrangement opening, replaces the part rib of the groove on the support section 1, inlays to connect or cohere on support section 1.
Claims (2)
1, a kind of high temperature resistant breaker arc extinguishing cover, comprise support section (1) and grid sheet (2), it is characterized in that: the solid cuboid that described support section (1) forms for ceramic roasting, it is the opening of V-arrangement that the cross section is wherein arranged on the end face, aperture position has the groove of some and parallel sided, and support section (1) bottom surface has two rankings to put the through hole that staggers; Grid sheet (2) is the rectangular metal sheet of band V-arrangement opening, replaces the part rib of the groove on the support section (1).
2, arc-extinguish chamber according to claim 1 is characterized in that: described grid sheet (2) and support section (1) are connected or cohere for inlaying.
