Abstract

The utility model discloses a novel transformer holder which comprises at least three base units made of conducting material and through-grooves are formed on each base unit to divide the base unit into an outer column, a connecting part and an inner column, wherein the outer columns and the inner columns are integrally connected through the connecting parts positioned at the bottoms of the through-grooves; when all the base units are assembled together, the through-grooves are in end-to-end connection to form an upward-opening ring-shaped groove for accommodating an iron core and a primary winding; the side walls of all the inner columns get close in sequence to form a middle column and positioned on the inner side of the ring-shaped groove; and all the outer columns are positioned outside the ring-shaped groove. The novel transformer holder has a simple structure, is convenient to install, eliminates the need for welding the parts, achieves the standardization of the parts, and is particularly suitable for industrial production. Owing to the large conductive area and the great convenience for achieving heavy-current output, the transformer holder as the auxiliary edge is particularly suitable for being used in the heavy-current occasions. Besides, the novel transformer holder has a large cooling area and a good heat dissipation effect and is extremely easy to achieve the cooling modes such as forced air cooling, forced water cooling and forced oil cooling.

[embodiment]

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

As Figure 14, the utility model is the transformer pedestal, comprise at least 3 base units of making by electric conducting material 1, on each base unit 1, have the groove 4 that it is divided into column jacket 51, connecting portion 52 and inner prop 53, column jacket 51 and inner prop 53 are connected as a single entity by the connecting portion 52 of groove 4 bottoms, all base unit 1 assembling one time-outs, all groove 4 head and the tail relatively just form opening annular groove 40 up, are used for placing iron core 2 and former limit winding 3.Mutually near forming center pillar 50, center pillar 50 is positioned at the inboard of annular groove 40 to all inner prop 53 sidewalls in turn, and all column jackets 51 are positioned at the outside of annular groove 40.After all base units 1 combination fixed, the former limit winding 3 that is wrapped on the iron core 2 is placed in the annular groove 40 of transformer pedestal, the center pillar 50 that the inner prop 53 of at this moment all base units 1 forms exposes from the centre bore of former limit winding 3, has made novel transformer.In the utility model, the groove 4 of described base unit 1 is deep-slotted chip breaker or rectangle combination slot, and described annular groove 40 is annular groove or square cannelure.Described base unit 1 profile is a square column type.All base unit 1 assemblings back profile together are square column type.
