The technical scheme that the utility model is taked for achieving the above object is:

A kind of novel transformer pedestal, it is characterized in that: include the pedestal of making by electric conducting material, in this pedestal, have the groove that is used for placing iron core and is wrapped in the former limit winding on the iron core, in this groove, be provided with one and can realize the center pillar of current lead-through, two openings in the two ends of described groove and the formation of the side of pedestal with this pedestal.

Aforesaid a kind of novel transformer pedestal is characterized in that: be provided with cooling chamber in described pedestal, the import of described cooling chamber, outlet communicate with the cooling fluid in the external world.

Aforesaid a kind of novel transformer pedestal is characterized in that: described pedestal and middle column bottom fuse.

Aforesaid a kind of novel transformer pedestal is characterized in that: described pedestal profile is square column type or semicircle.

Aforesaid a kind of novel transformer pedestal is characterized in that: described center pillar profile is square column type or semicircle.

Aforesaid a kind of novel transformer pedestal is characterized in that: described groove is for semicircle or square.

Aforesaid a kind of novel transformer pedestal is characterized in that: described cooling fluid is water, oil or wind etc.

Advantage of the present utility model has:

1, simple in structure, easy for installation, the complete exemption welding, component standardization, the utmost point is suitable for suitability for industrialized production;

2, the pedestal as secondary is big owing to conductive area, realizes that big electric current output is very simple, is particularly suitable for big current applications;

3, big, the good heat dissipation effect of film-cooled heat very easily realizes the type of cooling of forced air cooling, water-cooled and oil cooling.

[embodiment]

The utility model will be further described below in conjunction with accompanying drawing and embodiment:

The utility model is a kind of novel transformer pedestal, it includes the pedestal of being made by electric conducting material 1, in this pedestal 1, have the groove 4 that is used for placing iron core 2 and is wrapped in the former limit winding 3 on the iron core 2, in this groove 4, be provided with one and can realize the center pillar 5 of current lead-through, two openings 8 of side formation of the two ends of groove 4 and pedestal 1 with this pedestal 1.

When installing and using, embodiment shown in Fig. 5,6 is two this transformer pedestals (calling left and right transformer pedestal at this) opening 8 corresponding opening end faces 81 Face to face in opposite directions, and between the transformer pedestal, be provided with an insulating barrier 9, at this moment their groove 4 forms the closed recess that can place former limit winding 3 in the horizontal direction, then the former limit winding 3 that is wrapped on the iron core 2 is placed in the closed recess, at this moment the center pillar 5 in each pedestal 1 all exposes from the centre bore of former limit winding 3.The two ends 31,32 of former limit winding 3 are connected with input voltage; After then the center pillar 5 of the pedestal upper surface 101 of left transformer pedestal and right transformer pedestal being connected together, two shared secondary outputs of formation link to each other with centre tap 10, the center pillar 5 of left side transformer pedestal and the secondary tap that becomes left transformer pedestal after another secondary output 11 of left transformer pedestal links to each other, it and centre tap 10 have formed the left secondary winding of left transformer; The pedestal upper surface 101 of right transformer pedestal and the secondary tap that becomes right transformer pedestal after another secondary output 12 of right transformer pedestal links to each other, it and centre tap 10 have formed the right secondary winding of right transformer, so in Fig. 5,6 embodiment, two secondary windings of transformer have been formed, they are equivalent to the secondary around iron core 2 one circles separately, the conductive area of two secondary is big, all can realize exporting big electric current.

Certainly, also can only make transformer with a transformer pedestal, at this moment being wrapped in after former limit winding 3 on the iron core 2 is placed in the groove 4, the part of former limit winding is exposed present external, form the secondary that is equivalent to around iron core 2 one circles like this between pedestal upper surface 101 and the center pillar upper surface 51, can realize exporting big electric current equally.

In the present embodiment, pedestal 1 and center pillar 5 bottoms fuse.

Pedestal 1 can be made solid, and this transformer adopts the air-cooled type of cooling usually.

Certainly, pedestal 1 also can be made hollow, in pedestal, be provided with cooling chamber 6, the import and export 61,62 of cooling chamber 6 communicates with the cooling fluid in the external world, cooling fluid flows into from the import 61 of cooling chamber 6, and carry out heat exchange with transformer, a large amount of heats that transformer work produces are taken away, thereby further improved the cooling effect of transformer.Cooling fluid can be gaseous state, fluid liquids such as water, oil or wind.

Among the embodiment shown in Figure 1, base unit 1, profile are square column type, can certainly make half round post etc.Center pillar 5 can be half round post or square column type etc. also, and groove 4 can be square or semicircle, and the shape of groove 4 and center pillar 5 is to be complementary with the profile of former limit winding 3 and the centre bore of Qi Nei basically, and so better appearance also can be saved material.
