Abstract

The utility model provides a kind of retaining wall type transformer, comprising: transformer body; Barricade, is only extended in the horizontal direction by the side of transformer body, and barricade protrudes from the outside of transformer body; First pin, is arranged on the edge away from transformer body of barricade.Owing to being provided with outstanding barricade in the side of transformer body, and the first pin is arranged on barricade, therefore while reduction volume, adds creepage distance of the present utility model, improve fail safe, have the advantages that structure is simple, cost is low.

Description

Retaining wall type transformer

Technical field

The utility model relates to field transformer, particularly a kind of retaining wall type transformer.

Background technology

Volume of transformer of the prior art is comparatively large, is difficult to the occasion being applicable to volume of transformer be had to strict demand.Under normal circumstances, if when reducing volume of transformer with the occasion of transformer with small volume of satisfying the demand, because volume of transformer is less, its creepage distance also correspondingly shortens, and is difficult to meet safety requirements.

Utility model content

The utility model provides that a kind of structure is simple, cost is low, volume is little but still has the retaining wall type transformer of enough creepage distances.

For solving the problem, as an aspect of the present utility model, providing a kind of retaining wall type transformer, comprising: transformer body; Barricade, is only extended in the horizontal direction by the side of transformer body, and barricade protrudes from the outside of transformer body; First pin, is arranged on the edge away from transformer body of barricade.

Preferably, barricade is provided with four the first pins.

Preferably, retaining wall type transformer also comprise be arranged on transformer body with multiple second pins of barricade relative to side.

Owing to being provided with outstanding barricade in the side of transformer body, and the first pin is arranged on barricade, therefore while reduction volume, adds creepage distance of the present utility model, improve fail safe, have the advantages that structure is simple, cost is low.

Accompanying drawing explanation

Fig. 1 schematically shows structural representation of the present utility model.

Reference numeral in figure: 1, transformer body; 2, barricade; 3, the first pin; 4, the second pin.

Embodiment

Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.

Please refer to Fig. 1, the utility model relates to a kind of retaining wall type transformer, comprising: transformer body 1; Barricade 2, is only extended in the horizontal direction by the side of transformer body 1, and barricade 2 protrudes from the outside of transformer body 1; First pin 3, is arranged on the edge away from transformer body 1 of barricade 2.

Owing to being provided with outstanding barricade 2 in the side of transformer body 1, and the first pin 3 is arranged on barricade 2, therefore while reduction volume, add creepage distance of the present utility model, still can meet the requirement of fail safe, have the advantages that structure is simple, cost is low.

Preferably, barricade 2 is provided with four the first pins 3.

Preferably, retaining wall type transformer also comprises multiple second pin 4 of the side relative to barricade 2 be arranged on transformer body 1.

These are only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
