The split type fusing part specially used for the vacuum contactor-fuse combined electrical apparatus has the advantages that: the product is separately solidified by employing an APG (Alkyl Polyglucoside) epoxide resin solid sealing technology; the phase intervals can be adjusted according to requirements when assembling a contactor or contactor-fuse combined electrical apparatus; the split type fusing part specially used for the vacuum contactor-fuse combined electrical apparatus has the characteristics of high standardization degree, convenient operation and maintenance, and the like, and has a novel product structure, perfect functions and high dimension precision; as the APG (Alkyl Polyglucoside) epoxide resin technology is employed, the insulation performance and reliability of the product are greatly improved.
Description
Technical field
The utility model relates to the special-purpose split type fusing parts of a kind of vacuum contactor-fuse combined electric apparatus, belong to the design and fabrication technology field of medium voltage switchgear equipment.
Background technology
In the high-voltage electrical apparatus technical field, the used fusing part of vacuum contactor-fuse combined electric apparatus is all assembled by fuse and electric-conductor, insulating part etc., adopts air insulation at present, unenclosed construction, the overall dimension precision is low, the properties of product less stable, and the degree of product standardization is low.
Summary of the invention
The utility model proposes the special-purpose split type fusing parts of a kind of vacuum contactor-fuse combined electric apparatus; its objective is overcoming the above-mentioned defective of existing in prior technology, can be assembled into split solid-sealing vacuum contactor-fuse combined electric apparatus and in electric power system, protect and control various motor, transformer, capacitor.Spaced apart can be adjusted as requested after being assembled into vacuum contactor-fuse combined electric apparatus, has the standardization level height, characteristics such as reliability height, handled easily and maintenance.
Technical solution of the present utility model: it is characterized in that comprising back cover part, the striker parts, the connector fixed head, A fuse connector component, fuse part, molten cartridge unit, B fuse connector component, connect contact component, conductive pole, be flexible coupling, the insulation screw, conductive ring, conductive ring and conductive pole are enclosed in admittedly by epoxy resin forms molten cartridge unit together, A fuse connector component, B fuse connector component is fixed by bolts on conductive pole and the connector fixed head, the connector fixed head is fixed on the conductive ring, fuse frame is contained in A fuse connector component, on the B fuse connector component, fuse part
Cross φ 4-φ 7 through holes and link to each other with pole in the combined electrical apparatus, it is on the connector fixed head that the striker parts are fixed by bolts to, back cover part by the insulation screw on molten cartridge unit.
Advantage of the present utility model: product adopts the solid encapsulation technique split of APG epoxy resin to seal admittedly, and spaced apart can be adjusted as requested when being assembled into contactor or contactor-fuse combined electric apparatus, has the standardization level height, characteristics such as handled easily and maintenance; The product structure novelty, complete function, dimensional accuracy height; The epoxy resin APG technology that adopts has improved the insulation property and the reliability of product greatly.Solved the installation of traditional F-C loop fuse and fixedly be that electrified body is exposed to airborne problem, solved the problem of mutually insulated between the electrification device that is assembled into behind vacuum contactor-fuse combined electric apparatus simultaneously, and split typely take up room for a short time, be assembled into behind vacuum contactor or the vacuum contactor-fuse combined electric apparatus and can change separately after adjustable, any phase fuse blows of spaced apart.
Description of drawings
Accompanying drawing 1 is a sectional structure schematic diagram of the present utility model.
Accompanying drawing 2 is right TV structure schematic diagrames of the present utility model.
Accompanying drawing 3 is the structural representations of looking up of the present utility model.
Among the figure 1 is back cover part, the 2nd, and striker parts, the 3rd, connector fixed head, the 4th, A fuse
Connector component, the 5th, fuse part, the 6th, molten cartridge unit, the 7th, B fuse connector component, the 8th, connect contact component, 9 conductive poles, the 10th, conduction connects, and the 11st, insulation screw, the 12nd, conductive ring, the 13rd, φ 4-φ 7 through holes.
Embodiment
The contrast accompanying drawing, its structure is to comprise back cover part 1, striker parts 2, connector fixed head 3, A fuse connector component 4, fuse part 5, molten cartridge unit 6, B be fuse connector component 7, connect contact component 8, conductive pole 9, be flexible coupling 10, insulation screw 11, conductive ring 12, wherein molten cartridge unit 6 is formed by epoxy resin cylindrical outer casing and conductive ring 12 and the solid together envelope of conductive pole 9, has increased dielectric strength.A fuse connector component 4, B fuse connector component 7 are fixed by bolts on conductive pole 9 and the connector fixed head 3, and 5 of fuses are contained on A fuse connector component 4, the B fuse connector component 7.φ 4-φ 7 through holes 13 are used for linking to each other with the pole of combined electrical apparatus in fuse part 5 bottoms.It is on the connector fixed head 3 that striker parts 2 are fixed by bolts to, and connector fixed head 3 is fixed on the conductive ring 12, and conduction connection 10 is fixed on the other end of conductive ring 12, and conduction connects 10 other ends and links to each other with the current-carrying part of pole in the combined electrical apparatus.Back cover part 1 is to be fixed on the molten cartridge unit 6 with insulation screw 11.
When these fusing parts moved in circuit, fuse will fuse and expand when circuital current reached scheduled current, and the back of expanding is gone out to striker parts 2, and the striker parts drive the combined electrical apparatus action, thereby realized cut-offfing of circuit.
