Abstract
The invention relates to a fuse, in particular to a flat plate type vortex-shaped fuse, which is provided with an insulated shell. A halving wiring groove is arranged in the insulated shell and is made of two half parts. Each half part is made of arc resistant material. The halving wiring groove is a plane divergent polygonal vortex-shaped wiring groove formed between vortex-shaped continuous involute insulating ribs. Fusant grooves are arranged in the polygonal vortex-shaped wiring groove. The two half parts are assembled together in a way that ribs face to grooves and grooves faces to ribs. After assembling, the cross section is a continuous S-shaped passage. The insulating ribs are arranged between adjacent rings of the polygonal vortex-shaped wiring groove. Fusants are inlaid in the fusant grooves. An outgoing cable for leading out the two poles of the fusants from the inside is connected on the insulated shell. The invention mainly solves the technical problem that the existing columnar fuse is not applicable in compact places because of needing enough space in the longitudinal direction. Through changing the internal structure and the external structure of the product, the longitudinal insulation is changed to the transverse insulation and the columnar fuse is changed to the flat plate type fuse, so the height of the fuse is reduced.
Description
Technical field
The present invention relates to fuse, particularly a kind of flat plate type vortex-shaped fuse.
Background technology
Mostly existing fuse is column, and its profile has certain length, mainly is because will consider fuse in the electric insulation intensity of cut-offfing the two ends, back, therefore needs enough installing space and insulation distance in the vertical.By present fuse overall structure, the electric pressure of fuse entire length and system is the certain proportion relation, and from field demand, in some compact occasion, longitudinal length is no longer suitable than long fuse.
Summary of the invention
The object of the present invention is to provide a kind of flat plate type vortex-shaped fuse; Mainly solve existing column fuse and need enough spaces in the vertical; So that the technical problem that in some compact occasion, no longer is suitable for, it will vertically insulate and change into lateral isolation through the change to the inside and outside structure of product; Change into tabular from column, thereby the height of fuse is reduced.
For realizing above-mentioned purpose, the present invention is achieved in that
A kind of flat plate type vortex-shaped fuse is characterized in that: it has insulation crust, is provided with line embedding groove in this insulation crust; This is made up of two and half ones line embedding groove, and each half one adopts electric arc resistant material to process, and its structure is the polygon vortex-like wire casing of the plane divergence expression that forms between the vortex-like insulation muscle of gradually opening continuously, has melt tank in the polygon vortex-like wire casing; Two and half ones carry out assembly to groove, groove to muscle with muscle each other, and the cross section is the continuous S-shaped passage after the assembly; Be the insulation muscle between the polygon vortex-like wire casing adjacent turn; Be embedded melt in the described melt tank, be connected with on the insulation crust melt the two poles of the earth from interior outgoing cable of drawing.
Described flat plate type vortex-shaped fuse is characterized in that: described insulation crust is an insulating cement.
Described flat plate type vortex-shaped fuse is characterized in that: described electric arc resistant material is selected epoxy resin or DMC or SMC for use.
Described flat plate type vortex-shaped fuse is characterized in that: described fuse embeds the inner combined electrical apparatus that forms of electrical equipment.
Described flat plate type vortex-shaped fuse is characterized in that: a plurality of series connection of described fuse are used.
By said structure, the invention has the advantages that:
1, the present invention will vertically be insulated and changed into lateral isolation, change into tabular from column, thereby realize the purpose of the height reduction of fuse is saved the demand to site space.
2, the present invention utilizes two vortex-like grooves that can embed each other, and the electric straight line insulation distance between fuse the two poles of the earth is become S shape insulation distance, strengthens creepage insulation distance, reaches the purpose of dwindling the fuse volume.
3, fuse external electrical of the present invention is totally-enclosed, and the two poles of the earth are drawn and adopted the sealing insulated cable to draw, and increase outer creepage distance, to satisfy the GB requirement.

Embodiment
See also Fig. 1-3, it is the structural representation of a kind of flat plate type vortex-shaped fuse of the present invention.As shown in the figure: it has insulation crust 1, is provided with line embedding groove in this insulation crust 1; This is made up of two and half ones line embedding groove, and each half one adopts electric arc resistant material to process, and its structure is the polygon vortex-like wire casing 2 of the plane divergence expression of formation between the vortex-like insulation muscle of gradually opening continuously 3, has melt tank 21 in the polygon vortex-like wire casing 2; Two and half ones carry out assembly to groove, groove to muscle with muscle each other, and the cross section is the continuous S-shaped passage after the assembly; Be insulation muscle 3 between polygon vortex-like wire casing 2 adjacent turns; Be embedded melt in the described melt tank 21, be connected with on the insulation crust 1 melt the two poles of the earth from the interior outgoing cable of drawing 4.Described insulation crust 1 is an insulating cement.Described electric arc resistant material is selected epoxy resin or DMC or SMC for use.
Described melt tank 21 is exactly a gap; Be used for embedding fixing melt, melt is soft, coil in the vortex-like wire casing of gradually opening 2 in wire casing, to do some fixing points; Melt is pulled into polygonal structure adaptation to be fixed in the groove; Melt should not contact with other inwall large tracts of land, because need surround with quartz sand around the melt, the position of line embedding groove and fuse groove is concerned nearly orthogonal.
Flat plate type vortex-shaped fuse characteristics of the present invention are:
(1) height can be reduced to 10% ~ 15% of traditional fuse, saves a large amount of installing spaces.
(2) there is not outer creepage worry, safe and reliable.
(3) can be embedded in the inner combined electrical apparatus that forms of other electrical equipment; For example, voltage transformer must be joined fuse, and this fuse is longer, and the length of 10kv system will have 200mm many, and just passable with the maximum 50mm of fuse structure of the present invention, can together make with voltage transformer.
(4) can a plurality of series connection use; Fuse of the present invention has only two outlets not have polarity, and just as the series connection of resistance, the later effect of connecting is to increase connecting-disconnecting function.
