Abstract

The utility model discloses a novel low-voltage high-power water-cooled transformer, and relates to the technical field of transformers. The novel low-voltage high-power water-cooled transformer comprises an iron core, a primary coil wound on the iron core, a secondary coil wound on the primary coil and a fixing frame. The novel low-voltage high-power water-cooled transformer is characterized in that the secondary coil is made of a hollow copper pipe, water pipe joints used for being connected with external water pipes are arranged at the two ends of the hollow copper pipe, binding posts used for facilitating the external connection of the water-cooled transformer are further arranged at the two ends of the hollow copper pipe, and cross-over blocks are arranged between adjacent turns of the secondary coil. Due to the face that the secondary coil of the novel low-voltage high-power water-cooled transformer is made of the hollow copper pipe, the hollow copper pipe plays the role of the secondary coil, and also plays the role of a cold water circulating pipe, and therefore the novel low-voltage high-power water-cooled transformer has a better radiating effect compared with a traditional air-cooled transformer and is smaller in size compared with a traditional water-cooled transformer.

Description

A kind of New Low Voltage high-power water-cooled transformer
Technical field
The utility model relates to transformer technology field, particularly relates to a kind of New Low Voltage high-power water-cooled transformer.
Background technology
As everyone knows, transformer is one of electric equipment often using in people's production process, at present, traditional transformer is mainly divided into two kinds of air-cooled transformer and water-cooled transformers according to radiating mode, wherein, thereby air-cooled transformer is mainly to rely on cross-ventilation to take away the heat energy that transformer produces, water-cooled transformer is by laying cold water pipe, rely on the heat energy that circulates and then take away transformer generation of water, but practice is found, the radiating efficiency of air-cooled transformer is lower, tradition water-cooled transformer is owing to having laid a large amount of water pipes, therefore cause volume ratio larger.
Utility model content
The technical problems to be solved in the utility model is: provide that a kind of volume is little, the New Low Voltage high-power water-cooled transformer of perfect heat-dissipating.
The technical scheme that the utility model is taked for the technical problem existing in solution known technology is:
A kind of New Low Voltage high-power water-cooled transformer, comprises iron core, is around in primary coil on described iron core, is around in secondary coil and fixed frame on described primary coil; It is characterized in that: described secondary coil is made up of hollow copper tubing, be provided with the water pipe head that is connected use with outer water tube at the two ends of described hollow copper tubing, be also provided with and be convenient to water-cooled transformer is connected use binding post with peripheral hardware at the two ends of described hollow copper tubing; Between the adjacent turn of described secondary coil, be provided with cross-over block.
As optimal technical scheme, the utility model has also adopted following technical characterictic:
The end face of described hollow copper tubing is rectangle.
Advantage and the good effect that the utlity model has are: because the secondary coil in the utility model is made up of hollow copper tubing, therefore hollow copper tubing is born the role of secondary coil on the one hand, bear on the other hand the role of cool water circulating pipe, therefore compare with traditional air-cooled transformer, there is better radiating effect, compare with traditional water-cooled transformer, there is less volume.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model;
Fig. 2 is end view of the present utility model.
Wherein: 1, secondary coil; 2, cross-over block; 3, binding post; 4, water pipe head.
Embodiment
For further understanding utility model content of the present utility model, Characteristic, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1 and Fig. 2, a kind of New Low Voltage high-power water-cooled transformer, comprises iron core, is around in primary coil on described iron core, is around in secondary coil 1 and fixed frame on described primary coil; Wherein: in order not increase under the prerequisite of volume, guarantee the heat dispersion of transformer, secondary coil 1 in this specific embodiment is made up of hollow copper tubing, primary coil is made up of copper cash, be provided with the water pipe head 4 that is connected use with outer water tube at the two ends of described hollow copper tubing, be also provided with and be convenient to water-cooled transformer is connected use binding post 3 with peripheral hardware at the two ends of described hollow copper tubing; In order to guarantee the security performance of transformer, this specific embodiment is provided with cross-over block 2 between the adjacent turn of secondary coil 1.
As preferred embodiment, in order to prevent cross-over block 2 landings, the end face of the hollow copper tubing in above-mentioned specific embodiment is rectangle; Like this, cross-over block 2 is subject to secondary coil 1 clamping force of both sides, thereby has higher steadiness.
Use principle of the present utility model is: outer water tube is connected with water pipe head 4, and outside circulating water enters from one end of hollow copper tubing like this, and the other end is got rid of, and finally takes away the heat energy that transformer produces.
Above embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalizations of doing according to the utility model application range change and improve, within all should still belonging to patent covering scope of the present utility model.
