Background technology
The high pressure pour mass of dry-type transformer is wrapped in the periphery of high-tension coil, is to be formed outward at high-tension coil with poured with epoxy resin under vacuum conditions.See Fig. 1 and Fig. 2, when pouring into a mould high pressure pour mass 1, needing to form two outwardly main electrical scheme ends 11 and multiple points of terminals 12 in the side of high pressure pour mass 1, in main electrical scheme end 11 and point terminals 12, being provided with wiring copper nut; Described main electrical scheme end 11 and point terminals 12 obtain by arranging cast panel in casting mold.See Fig. 3 ~ Fig. 5, existing cast panel 2 is most adopts channel-section steel structure, and the panel of channel-section steel be welded with for the formation of described main electrical scheme end and divide the main electrical scheme seat 21 of the outwardly convex of terminals and divide a junction block 22, the side of channel-section steel forms sealing surface a; This cast panel 2 has the following disadvantages:
1, because the evenness of channel-section steel own is not high, therefore use channel-section steel as cast panel time, need to carry out polishing to sealing surface and make evenness reach designing requirement, in the course of processing, operation is more, and processing after sealing surface intensity undesirable, be easily out of shape.
2, junction block mould processing technology is complicated, and the time is long, and waste material.
3, junction block welding requirements is high, and therefore in production process, process is many, and technological requirement is also higher, and the time is long, and cost is high.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of dry transformer pouring panel, and this cast panel has that structure is simple, easy to process, precision is high, low cost and other advantages.
The technical scheme that the utility model solves the problems of the technologies described above is:
A kind of dry transformer pouring panel, comprise the panel body and side plate be made up of steel plate, the two ends of panel body are provided with two main electrical scheme seats; It is characterized in that, the middle part of described panel body is provided with the projection formed by outside bending, and this projection is provided with point wiring hole for being connected with the wiring copper nut in point terminals of high pressure pour mass.
A preferred version of the present utility model, wherein, described point of wiring hole is the uiform section circular hole matched with wiring nut size.Have advantage easy to process like this, described uiform section circular hole is by drilling machine or milling machine processing.
A preferred version of the present utility model, wherein, described point of wiring hole is shoulder hole, and size and the wiring nut size of the path part of this shoulder hole match.Make wiring copper nut can be fixed better by high pressure pour mass like this.
A preferred version of the present utility model, wherein, described side plate forms one with between panel by welding.There is the advantage be connected firmly.
A preferred version of the present utility model, wherein, the distance between the outer surface of described projection and the outer surface of described panel body is 15mm ~ 30mm.To meet the requirement for height of point terminals.
A preferred version of the present utility model, wherein, the transition portion between described projection and main body panel is flat or arc-shaped.Make smooth transition between two parts, prevent stress and concentrate.
The utility model compared with prior art has following beneficial effect:
1, by arranging the projection that outside bending is formed at the middle part of panel body, and point wiring hole be connected with the wiring copper nut in point terminals of high pressure pour mass is set on this projection, thus substitute of the prior art point of junction block, not only eliminate baroque point of junction block, and also eliminate the technique of welding point junction block, not only structure is more simple, and production technology have also been obtained and simplifies greatly.
2, described panel body and side plate carry out cutting by Water Cutting technology to steel plate and form, and not only mechanical strength is high, and size is accurate, and surface quality is good.
3, the more existing channel-section steel of mechanical strength due to panel body and side plate is high a lot, therefore there will not be and causes transformer coil to build the problem of hourglass material because of rigidity or undercapacity.
