Problems solved by technology

[0003] When the transformer substituting load is heavy, it is necessary to use an external cooling device to assist in cooling the transformer. When the existing external cooling device blows the airflow to the surface of the transformer, its blowing range is difficult to adjust according to the actual cooling requirements of the transformer. The limitations of use more sexual

Embodiment 1

[0024] like figure 1 , 2 As shown in Fig. 5, a transformer cooling device includes a fan 1 and a current booster assembly 2. The front end of the fan 1 is bolted with a current booster assembly 2, and a diffuser assembly 3 is inserted at the center of the current booster assembly 2. The diffuser assembly 3 includes Adjustment pipe 31 and diffuser cover 32, the adjustment pipe 31 is placed on the rear side of the diffuser cover 32, and the adjustment pipe 31 and the diffuser cover 32 are connected in a front and rear shape; the diffuser cover 32 is in the shape of a horn, and the surface of the diffuser cover 32 is distributed in a ring shape, etc. There are four grooves in the sub-cut; the annular outer wall of the adjusting pipe 31 is etched with threads, and the annular inner wall of the adjusting pipe 31 is provided with a handle.

[0025] In this embodiment, based on the diffuser assembly 3, the airflow blown by the fan 1 is diffused, that is, during use, the insertion de...

Embodiment 2

[0028] like Figure 1-4 As shown, a transformer cooling device, the current increasing assembly 2 includes a bushing 21, a screen 22, an annular frame 23 and a flow increasing channel 24, the front end of the fan 1 is fixed with an annular frame 23, and the annular wall of the annular frame 23 is distributed in an annular shape There are several flow-increasing passages 24 through the shape of the bisected; the annular frame 23 and the fan 1 are connected with a screen 22, and the screen 22 covers the port of the annular frame 23; the center of the screen 22 is vertically interspersed with a casing 21. The inner wall of the sleeve 21 is etched with threads;

[0029] In this embodiment, by setting the flow increasing channel 24 from the annular wall of the annular frame 23, and then in the air blowing, based on the negative pressure applied to the relatively static area in the high flow rate area, more air flow is blown into the annular area. In the frame 23, the blowing force...

Abstract

The invention provides a transformer cooling device, which relates to the field of transformers, and includes a fan and a flow increasing assembly. In the present invention, the front end of the fan is bolted with a flow increasing assembly, and the center of the flow increasing assembly is inserted with a diffusion assembly, and the diffusion assembly includes a regulating tube. And the diffusion cover, the adjustment tube is placed on the rear side of the diffusion cover, and the adjustment tube and the diffusion cover are connected front and rear; the diffusion cover is trumpet-shaped, and the surface of the diffusion cover is cut into four slots in a circular distribution, based on the diffusion cover It is in the form of a curved surface, and in the process of blowing the airflow, the airflow is diffused through the transition of the curved surface. After the diffusion treatment, the blowing range of the fan is greatly increased, so that the transformer can contact more blowing airflow during the heat dissipation process. Thus achieving faster and better heat dissipation.

Description

technical field [0001] The invention relates to the field of transformers, in particular to a transformer cooling device. Background technique [0002] Transformer is a static electrical equipment used to transform AC voltage and current and transmit AC power. It realizes power transfer according to the principle of electromagnetic induction. One or several devices with different voltages, that is, when the primary winding is connected to alternating current, an alternating magnetic flux is generated, and the alternating magnetic flux is induced by the magnetic conduction of the iron core, and an alternating electromotive force is induced in the secondary winding. The level of the secondary induced electromotive force is related to the number of turns of the primary and secondary windings, that is, the voltage is proportional to the number of turns; transformers can be divided into power transformers, test transformers, instrument transformers and special-purpose transformer...
