Description
Technical field
The present invention relates to post load switch product, specifically refer to a kind of double loop goat's horn outlet terminal.
Background technology
Existing goat's horn outlet terminal is mainly used on the products such as voltage-type on-load switch, user demarcation load switch, and it can increase phase spacing to greatest extent, effectively avoids alternate electric discharge phenomena occur between terminal.But, if think, primary voltage is got in face from it, must draw wire from the copper conductor at terminal center, inner, between lead-out wire and other electrified body of switch casing, lead-out wire and switch internal the electrical distance of goat's horn outlet terminal can be caused so inadequate, and electric discharge phenomena are more serious.
Summary of the invention
For above-mentioned deficiency of the prior art, the invention provides a kind of double loop goat's horn outlet terminal, it draws copper rod from center conductor, and is poured into a mould separately by epoxy resin, form an independently primary circuit, can effectively solve like this electrical distance not, the problem such as serious of discharging.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of double loop goat's horn outlet terminal, center conductor, copper rod that described terminal comprises metal annular cover and welds respectively with it, wherein said center conductor and metal annular cover coaxial welding, it is connected with electrical network output cable by the flat copper being positioned at port, described copper rod to be welded in below metal annular cover and to draw, described metal annular cover, center conductor and copper rod form a metal integral jointly, and described metal integral is shaped by poured with epoxy resin.
As the improvement of technique scheme, be positioned at the epoxy resin at described metal annular cover position, its surface spraying semi-conductive layer, it forms an annular capacitor with inner metal annular cover, can play balanced electric field action.
As the improvement of technique scheme, be positioned at the epoxy resin at described center conductor position, its surface casting has silicon rubber cluster parachute.
The beneficial effect that the present invention brings has:
Double loop of the present invention goat's horn outlet terminal, it is a kind of primary circuit lead-out wire being applied to post load switch outgoing line side, it is connected as major loop by the flat copper of terminal center conductor with the power transmission cable of electrical network, and the copper rod by being connected with center conductor, draw an other independent loop as minor loop, major loop can be used for circuit delivery of electrical energy, minor loop can be used as multiple use, it can take out circuit primary voltage, the electric equipment of needs can also be connected to simultaneously, in addition, goat's horn outlet terminal of the present invention adopts double loop integral type cast, cost is significantly lower than cable outlet terminal.
Accompanying drawing explanation
Below in conjunction with drawings and the specific embodiments, the invention will be further described,
Accompanying drawing 1 is double loop of the present invention goat's horn outlet terminal structure front view;
Accompanying drawing 2 is vertical face cross-sectional schematic of accompanying drawing 1;
Accompanying drawing 3 is double loop of the present invention goat's horn outlet terminal structure side views;
Accompanying drawing 4 is its root structure cutaway views of accompanying drawing 3;
Accompanying drawing 5 is double loop goat's horn outlet terminal effect figure of the present invention.
Embodiment
With reference to accompanying drawing 1 to accompanying drawing 4, double loop of the present invention goat's horn outlet terminal, it is by drawing the innovation point of branch's minor loop from the parallel connection of terminal major loop, efficiently solve inner, between lead-out wire and other electrified body of switch casing, lead-out wire and switch internal the electrical distance of goat's horn outlet terminal inadequate, the problem that electric discharge phenomena are serious.
This double loop goat's horn outlet terminal that independent minor loop except major loop, its lead-out mode is: a metal annular cover 2 be integrated with center conductor 1 coaxial welding, then weld a copper rod 3 from metal annular cover 2 to draw, making metal annular cover 2, center conductor 1 jointly form a metal integral with copper rod 3 by welding, afterwards metal integral being shaped by poured with epoxy resin.
Based on said structure, the present invention can adopt double loop integral type cast, make its cost significantly lower than common cable outlet terminal, its two circuit purposes is wider simultaneously, the major loop be connected with electrical network output cable by the flat copper 11 being positioned at center conductor 1 port can be used for circuit delivery of electrical energy, minor loop can take out circuit primary voltage, can be connected to again the electric equipment of needs, as being connected to electronics EVT voltage sensor etc.
Simultaneously in order to problem is put in better solution office, in the outside of double loop goat's horn outlet terminal, be positioned at its surface spraying semi-conductive layer 21 of epoxy resin at metal annular cover 2 position, it can form an annular capacitor with inner metal annular cover 2, plays the effect of balanced electric field; And being positioned at the epoxy resin at center conductor 1 position, its surface is then cast with silicon rubber cluster parachute 22, makes this product have a kind of version of unique outlook.
Another kind of embodiment of the present invention is: the independent minor loop be made up of copper rod 3 can not by metal annular cover 2, directly to be connected on center main conductor and to draw, and then center conductor 1 is poured into a mould together with copper rod 3, this structure also can realize the substantially identical effect of technique scheme.
The present invention is when being applied to voltage-type post load switch, with reference to accompanying drawing 5, reach three-phase input terminal and the three-phase outlet terminal of casing both sides can be designed to, and the section of stretching out of above-mentioned terminal is outwards radially arranged from casing both sides respectively, design like this can make the end-to-end distance of adjacent two terminals from greatly improving, thus ensure into and out of the air insulation distance between line terminals, improve the fail safe of equipment.
Finally, the above is preferred embodiment of the present invention, and the present invention is not limited to above-mentioned execution mode, as long as it reaches technique effect of the present invention with identical means, all should belong to protection scope of the present invention.
