As shown in Figure 1 to Figure 2, the first embodiment of the present utility model, a kind of combined transformer insulating cylinder, described insulating cylinder is vertical prismatic shape and the rectangular dielectric plate 1 that is arranged in order by 4 head and the tail surrounds around insulating cylinder axle center, it is fixedly connected by stay 2 between adjacent rectangle insulation board 1, the installed surface 21 of the rectangular dielectric plate 1 that each stay 2 correspondence is connected all has groove 22, and the connection side 11 of rectangular dielectric plate 1 embeds and is fixed in groove 22.
The structure of described rectangular dielectric plate 1 can refer to shown in Fig. 2, and the non-conterminous both sides of rectangular dielectric plate 1 connect side 11 as it.
The structure of described stay 2 can refer to shown in Fig. 1, and this stay is " L " shape stay, and its cross section is " L " the shape structure with rectangular shaped, apart from its corner farthest two sides be installed surface 21.Two installed surfaces 21 process the groove 22 of " one " shape respectively；Described groove 22 is this stay through groove along the axial two ends of insulating cylinder, and this groove is used for embedding connection side 11.The material selection epoxy resin of stay 2.
Described rectangular dielectric plate 1 and the connected mode of described stay 2, embed in groove 22 by the connection side 11 of rectangular dielectric plate 1, till the degree of depth of embedding reaches maximum.Due to groove 22 be connected between side 11 for matched in clearance, be easy to embed in groove 22 connect side 11, but also needing to be reinforced the connection between rectangular dielectric plate 1 and stay 2 by glue, additionally glue can be additionally used in and fills the gap connected between side 11 and groove 22.
The feature of the first embodiment:
1. the simple in construction described in present embodiment understands, fabrication cycle is short.Contrasting the structure of traditional disposal molding, present embodiment uses simple and sliceable fabricated structure, the most greatly shortens fabrication cycle.
2. conservation.Have only to can be achieved with various sizes of structure fabrication, for prior art by described rectangular dielectric plate 1 and described stay 2 are carried out cutting, it is not necessary to redesign mould, save the raw material making mould.
3. between rectangular dielectric plate 1 described by present embodiment and two stays 2 being connected with this rectangular dielectric plate, self-assembling formation heat dissipation wind channel.
As shown in Figures 3 to 6, improve on the basis of the embodiment above, as the second embodiment of the present utility model.Such as the overall structure schematic diagram that Fig. 3 is the second embodiment；Fig. 4 is the structural representation of rectangular dielectric plate in the second embodiment；Fig. 5 is that the structure of rectangular dielectric plate in the second embodiment splits schematic diagram；Fig. 6 is the structure for amplifying schematic diagram of stay in the second embodiment.
For the rectangular dielectric plate 1 described in the first embodiment, it is improved to the stacked structure with magnetic screening action, is understood for convenience, its structure is split.Can refer to shown in Fig. 4 and Fig. 5, rectangular dielectric plate 1 includes two layer of insulation board 13 and is clipped in the magnetic masking layer 12 in the middle of two layer of insulation board 13；Described magnetic masking layer 12 is the metal forming with magnetic conduction effect, and welds a lead-out tablet 121 for ground connection in this metal forming.Lead-out tablet 121 can be attached with outside earth lead, reaches too much energy to be discharged into the purpose of the earth.Here, layer of insulation board 13 material can select epoxy resin.
For the stay 2 described in the first embodiment, it thes improvement is that, processes several countersunk head screwed holes 24 on the outside of stay 2 and the face vertical with installed surface 21, and countersunk head screwed hole 24 is vertical with groove 22 to be communicated.
