Abstract
The invention relates to a glass fibre reinforced plastic capacitance multicore transformer bushing which not only has the functions of common transformer bushings, and what's more is capable of simultaneously leading out a plurality of through cable leads with similar voltages and belongs to the technical field of high-voltage engineering in dynamic and electronic engineering. Due to the fact that the traditional transformer no-load voltage-regulating tap is in the transformer, a test means for testing whether the contact between moving contacts and fixed contacts of the tap is reliable or not is lacking all along, whereas if the no-load voltage-regulating tap is arranged outside the transformer, the technical problem can be easily solved. In order to achieve the goal, the invention daringly orientates the key technical scheme under the premise that the internal structure of the transformer is not basically changed to realize the extraposition function of the no-load voltage-regulating tap only by a multicore bushing. Adopting the technology of the invention not only reduces the installation volume of the transformer but also greatly reduces the economic cost, and therefore, the transformer bushing can be widely applied to no-load voltage-regulating transformers.
Description
Technical field:
The present invention relates to a kind of glass fibre reinforced plastic capacitance multicore transformer bushing, except that function, also have and draw the close function of wearing the cable lead-in wire of a plurality of voltages simultaneously with common transformer sleeve pipe.
Background technology:
Because traditional transformer No-load changer tap is in transformer inside, after finishing the No-load changer operation, whether the contact between the dynamic/static contact of tap does not reliably have a kind of measuring means safe against all possibilities guarantees, if and the No-load changer tap can be placed the outside of transformer, then can address the above problem easily, thus the safety operation level of raising transformer.
For realizing the No-load changer tap is placed the purpose of transformer outside, a kind of simple method is exactly to provide a traditional bushing shell for transformer of wearing the cable formula for lead-in wire that each root links to each other with the no-load tap, but so both increased the volume of transformer, also extremely uneconomical.And the sleeve pipe of employing the art of this patent then can not change under the prerequisite of transformer internal structure substantially, only adopts a multicore sleeve pipe just can realize the external function of No-load changer tap.
Summary of the invention:
Purpose of the present invention aims to provide a kind of glass fibre reinforced plastic capacitance multicore transformer bushing, and it can also be drawn the many cables of wearing insulated from each other simultaneously and go between, to realize the external function of No-load changer tap except that the effect with general bushing shell for transformer.
Glass fibre reinforced plastic capacitance multicore transformer bushing provided by the invention comprises that is worn a cable formula bushing shell for transformer body, wears the cable lead-in wire for many, the outer rainproof member of all pressures of oil in insulating support between lead-in wire and the lead-in wire and the oil.Described to wear cable formula bushing shell for transformer body center be metal tube, and metal tube is outward the condenser bushing core body, and sleeving core is external flange component, and there is silicon rubber external insulation full skirt the open air.Described bushing shell for transformer body is realized bearing of high-tension insulation, sleeve pipe mechanical force.Wear cable lead-in wire and pass sleeve body for described many, expose at two ends, and an end has the binding post that passes the insulated enclosure plate, and two ends all have separate binding post.
Above-mentioned glass fibre reinforced plastic capacitance multicore transformer bushing to install and use mode as follows: bushing shell for transformer is installed on the transformer by flange, guarantees sealing between sleeve pipe and the transformer with sealing ring.Sleeve pipe oil terminated line mode is as follows: take off the anti-corona cover of bushing shell for transformer oil end, the oily terminated line terminal of sleeve pipe connects the lead-in wire of transformer coil, guarantee transformer lead insulation distance each other simultaneously, again oil is held anti-corona cover to be installed on the sleeve pipe after guaranteeing to connect reliable and insulation distance.The sleeve pipe outdoor end mode of connection is as follows: take off sleeve pipe rain cover topmost, introduce lead-in wire from the outdoor end opening, reliably be connected with sleeve pipe outdoor end binding post guaranteeing to go between under the prerequisite of lead-in wire and the insulation distance of any metal parts of sleeve pipe outdoor end, again the sleeve pipe rain cover be installed on the sleeve pipe at last.
The advantage of above-mentioned glass fibre reinforced plastic capacitance multicore transformer bushing is: the lead-in wire of many transformer No-load changer taps can be drawn transformer simultaneously, realize the external function of tap, glass fibre reinforced plastic capacitance multicore transformer bushing is the dry type product in addition, and have the following advantages that is: 1 simultaneously) there are not oil, no gas, no porcelain, explosion-proof, environmental protection, a maintenance less; 2) adopt novel insulation system, make that the sleeve pipe dielectric loss is little, office lowers, life expectancy is long, mechanical strength is high, anti-destructive is strong; 3) adopt woven wire capacitance plate patented technology, electrode is combined with fiberglass firmly, guaranteed insulation property better; 4) adopt the capacitance core body stress to cut apart the breaker patented technology, reduced the internal stress of electric capacity core body, improved the ability of product tolerance thermal shock.
Description of drawings:
Fig. 1 is the cutaway view of a kind of embodiment of the present invention.
Embodiment:
Below in conjunction with above-mentioned accompanying drawing, describe the present invention in detail.
Referring to Fig. 1, wherein shown a kind of according to glass fibre reinforced plastic capacitance multicore transformer bushing embodiment of the present invention, comprise that is worn a cable formula bushing shell for transformer body (1), wear cable lead-in wire (2), the outer rainproof member of all pressures (4) of oil in insulating support (3) between lead-in wire and the lead-in wire and the oil.
Wherein bushing shell for transformer body (1) has central metal pipe (11), silicon rubber full skirt (12), fiberglass electric capacity core body (13) and flange component (14), silicon rubber full skirt (12) is the external insulation of sleeve pipe, flange component (14) is the link of sleeve pipe and transformer.
