Description

Technical Field

[0001] The utility model relates to the field of transformers, and particularly to a transformer with two coils. Background Art

[0002] A transformer with two coils is usually also called a two-winding transformer, which is a transformer having two mutually independent and insulated windings. A two-coil transformer means that two windings (coils), namely a primary winding and a secondary winding, are sleeved on a single-phase iron core. This transformer realizes functions such as voltage transformation, impedance transformation, and isolation through the principle of electromagnetic induction. A two-winding transformer consists of two windings wound around the same iron core, and these two windings are interconnected through an alternating magnetic flux. Common shapes of the iron core include E-shaped and C-shaped. Among them, the E-shaped iron core transformer has a shell structure (the iron core wraps the coil), while the C-shaped iron core transformer has a core type structure (the coil wraps the iron core). When an alternating current (with a certain known frequency) flows into the primary winding, an alternating magnetic flux will be generated in the iron core. This alternating magnetic flux will pass through the secondary winding, thereby inducing an alternating voltage with the same frequency in the secondary winding. The magnitude of the induced voltage depends on the degree of coupling and magnetic cross-linking between the two coils, which is specifically determined by the turns ratio between the primary winding and the secondary winding. Therefore, by adjusting the turns ratio, the two-winding transformer can achieve voltage step-up or step-down. During the use of a two-winding transformer, it is often affected by external object collisions. When the two-winding transformer is affected by external object collisions, it is easily damaged by the impact object, thereby reducing the service life of the two-winding transformer. At the same time, a large amount of heat is generated during the operation of the two-winding transformer. If the heat cannot be dissipated in time, it will cause the temperature of the transformer to rise, thereby affecting its power factor, increasing voltage drop and losses, reducing the operating efficiency of the transformer, and the insulating material of the two-winding transformer is prone to aging, deterioration, and hardening in a high-temperature environment, thereby reducing the insulation strength and shortening the service life of the transformer. Summary of the Utility Model

[0003] The main purpose of the utility model is to provide a transformer with two coils, which can effectively solve the problems in the background art.

[0004] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

The installation protection bracket consists of a fixed frame and an L-shaped support plate structure. There are two L-shaped support plate structures, which are symmetrically and fixedly installed at the lower end of the fixed frame. A cooling fan is fixedly installed at the upper end of the fixed frame. A protection component is movably installed on the L-shaped support plate structure.

The anti-disengagement baffle is fixedly installed at the inner end of the installation square rod. The buffer protection spring is sleeved on the installation square rod. The C-shaped protection baffle is fixedly installed at the outer end of the installation square rod.

[0006] Preferably, the double-winding transformer consists of a transformer body and an installation base, and the transformer body and the installation base are fixedly connected.

Specific embodiments

[0018] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4As shown in the figure, a transformer with double coils includes a double-winding transformer 1. The double-winding transformer 1 is composed of a transformer body 5 and a mounting base 6, and the transformer body 5 and the mounting base 6 are fixedly connected. An installation protection bracket 2 is fixedly installed on the double-winding transformer 1. The installation protection bracket 2 is composed of a fixed frame 7 and an L-shaped support plate structure 8. There are two L-shaped support plate structures 8, which are symmetrically and fixedly installed at the lower end of the fixed frame 7. A cooling fan 3 is fixedly installed at the upper end of the fixed frame 7. A protection component 4 is movably installed on the L-shaped support plate structure 8. The protection component 4 is composed of an installation square rod 10, a anti-disengagement baffle 11, a buffer protection spring 12 and a C-shaped protection baffle 13. The anti-disengagement baffle 11 is fixedly installed at the inner end of the installation square rod 10. The buffer protection spring 12 is sleeved on the installation square rod 10. The C-shaped protection baffle 13 is fixedly installed at the outer end of the installation square rod 10. When in use, the installation protection bracket 2 and the protection component 4 can protect the double-winding transformer 1, thereby reducing the probability of the double-winding transformer 1 being collided by foreign objects, and further reducing the probability of the double-winding transformer 1 being damaged. When the C-shaped protection baffle 13 on the protection component 4 is collided by foreign objects, the C-shaped protection baffle 13 will move towards the L-shaped support plate structure 8. At this time, the buffer protection spring 12 will be compressed. During the process of the buffer protection spring 12 generating shrinkage deformation, the impact force generated by the collision can be weakened. When in use, the cooling fan 3 can be turned on. At this time, the cooling fan 3 can accelerate the heat dissipation of the double-winding transformer 1, thereby accelerating the heat dissipation efficiency of the double-winding transformer 1, and further making the temperature of the double-winding transformer 1 not easy to be too high, and finally further reducing the probability of the double-winding transformer 1 being damaged.

[0020] Furthermore, the fixed frame 7 on the installation protection bracket 2 is located above the double-winding transformer 1. The L-shaped support plate structure 8 is fixedly connected to the mounting base 6. An installation square hole 9 is opened on the L-shaped support plate structure 8 of the installation protection bracket 2. The installation square hole 9 penetrates through the L-shaped support plate structure 8 inside and outside. The installation square rod 10 on the protection component 4 is slidably installed inside and outside in the installation square hole 9 opened on the L-shaped support plate structure 8. The anti-disengagement baffle 11 is located inside the L-shaped support plate structure 8. The buffer protection spring 12 and the C-shaped protection baffle 13 are both located outside the L-shaped support plate structure 8. The installation protection bracket 2 plays a supporting role for the cooling fan 3 and the protection component 4. When the C-shaped protection baffle 13 on the protection component 4 is collided by foreign objects, it will move towards the L-shaped support plate structure 8. At this time, the installation square rod 10 will slide inwards in the installation square hole 9. At this time, the buffer protection spring 12 will be compressed by the C-shaped protection baffle 13. When the impact force disappears, under the elastic reaction force of the buffer protection spring 12, the C-shaped protection baffle 13 will be pushed outwards to reset. At this time, the installation square rod 10 will slide outwards in the installation square hole 9, and finally until the anti-disengagement baffle 11 contacts the inner end of the L-shaped support plate structure 8.

[0021] Further, the cooling fan 3 is fixedly installed on the fixed frame 7 of the installation protection bracket 2 by bolts, and the cooling fan 3 is located above the double-winding transformer 1. When the cooling fan 3 is started, the airflow generated by the operation of the cooling fan 3 will drive the airflow around the double-winding transformer 1 to flow, so that the heat dissipated by the double-winding transformer 1 can be quickly taken away, thereby reducing the accumulation of heat on the double-winding transformer 1, and ultimately achieving the purpose of accelerating the heat dissipation of the double-winding transformer 1.
