Description

Technical Field

[0001] The utility model relates to the technical field of transformers, in particular to a transformer temperature control device. Background Art

[0002] A transformer is an electrical device mainly used to convert the voltage of alternating current. It consists of two or more coils and uses the principle of electromagnetic induction to convert the input voltage into the required output voltage. The main components of the transformer include the primary coil, the secondary coil and the iron core. When alternating current passes through the primary coil, an alternating magnetic field is generated in the iron core, which in turn generates an induced electromotive force in the secondary coil, thereby changing the current. Transformers are widely used in power systems, electronic equipment, communication systems and other fields. They are key equipment for achieving efficient transmission and use of electric energy.

[0003] Transformers generate heat when working. Excessive temperature will cause aging of transformer insulation, performance degradation, and even cause safety accidents such as fire. It is particularly important to monitor and control the transformer temperature in real time. Therefore, transformer temperature control devices are urgently needed to solve the above problems.

At the same time, through the combination of the PLC controller and the temperature sensor, real-time monitoring and intelligent control of the internal temperature of the transformer are realized.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-5 The utility model provides an embodiment: a transformer temperature control device, including a transformer heat dissipation shell 1, a PLC controller 2, a top protective cover 3, a temperature sensor 7 and a heat dissipation guide disc 8, the outer side of the heat dissipation guide disc 8 is evenly and fixedly connected with four special-shaped guide grooves 9, the end of the special-shaped guide groove 9 away from the heat dissipation guide disc 8 is fixedly connected with a steering guide groove 10, the bottom end of the steering guide groove 10 is fixedly connected with a rainwater collecting groove 12, and the bottom end of the rainwater collecting groove 12 is penetrated with a drainage hole groove 13. When it rains, the rainwater received in the steering guide groove 10 can be discharged through the drainage hole groove 13 opened at the bottom end of the rainwater collecting groove 12, and a heat dissipation fan 11 is fixedly installed at the bottom end of the heat dissipation guide disc 8.

[0023] The top of the transformer heat dissipation shell 1 is fixedly connected with an installation fixing frame 6, the bottom of the transformer heat dissipation shell 1 is symmetrically fixedly connected with two installation support frames 5, and the outer side of the transformer heat dissipation shell 1 is evenly fixedly connected with heat dissipation fins 4. When the transformer inside the transformer heat dissipation shell 1 generates heat, it is absorbed by the transformer heat dissipation shell 1. At the same time, the transformer heat dissipation shell 1 transfers the heat to the heat dissipation fins 4, and the heat dissipation fins 4 then diffuse the heat to the external air, thereby achieving a heat dissipation effect.

[0024] The PLC controller 2 is electrically connected to the temperature sensor 7 and the cooling fan 11 by wires, respectively. By setting the control program and temperature threshold for the PLC controller 2, the PLC controller 2 analyzes the temperature data transmitted in real time by the temperature sensor 7. When the temperature data received by the PLC controller 2 reaches the threshold, a start instruction is sent to the cooling fan 11 to accelerate heat dissipation.

[0025] The top protective cover 3 is fixedly mounted on the outside of the top of the mounting frame 6, the PLC controller 2 is fixedly mounted on the top of the top protective cover 3, and the temperature sensor 7 is fixedly mounted on the inner side of the transformer heat dissipation casing 1. The temperature sensor 7 can monitor the temperature data inside the transformer heat dissipation casing 1 in real time inside the transformer heat dissipation casing 1, and the temperature sensor 7 transmits the monitored temperature data to the PLC controller 2.

[0026] The top of the heat dissipation guide disc 8 is fixedly connected to the bottom end of the transformer heat dissipation shell 1, and the top of the special-shaped guide groove 9 is fixedly connected to the bottom end of the transformer heat dissipation shell 1. After the heat dissipation fan 11 is started, the air at the bottom is transported to the heat dissipation guide disc 8. Since the special-shaped guide groove 9 is located on the outside of the heat dissipation guide disc 8, the airflow in the heat dissipation guide disc 8 flows around through the special-shaped guide groove 9 and is transported to the turning guide groove 10.

[0027] The heat dissipation fins 4 are evenly arranged on the outside of the transformer heat dissipation housing 1, and the top of the turning guide groove 10 is located directly below the heat dissipation fins 4. The side of the turning guide groove 10 away from the special-shaped guide groove 9 is designed in an arc shape. The arc design can make the airflow entering the turning guide groove 10 turn more smoothly. The airflow after turning is inclined to flow toward the outside of the transformer heat dissipation housing 1. Since the turning guide groove 10 is located directly below the heat dissipation fins 4, the airflow flows upward through the gaps between the heat dissipation fins 4, thereby accelerating the heat dissipation efficiency of the heat dissipation fins 4.

[0028] Working principle: During use, first set the control program for the PLC controller 2 and set the temperature threshold. Then install the transformer inside the transformer heat dissipation casing 1, and fix the top protective cover 3 to the outside of the top of the installation fixing frame 6 by bolts. When the transformer is turned on, the heat generated by the transformer is transferred to the heat dissipation fins 4 on the outside through the transformer heat dissipation casing 1. The heat dissipation fins 4 diffuse the heat into the air to achieve the heat dissipation effect. At the same time, the temperature sensor 7 transfers the temperature inside the transformer heat dissipation casing 1 to the PLC controller 2 in real time. When the temperature data received by the PLC controller 2 reaches the predetermined threshold, the PLC controller 2 controls the cooling fan 11 to start, and the cooling fan 11 passes through the heat dissipation guide disc. 8 pushes the airflow into the special-shaped guide groove 9, and the airflow flows into the inside of the steering guide groove 10 through the special-shaped guide groove 9. Through the arc design of the steering guide groove 10, the airflow in the steering guide groove 10 is turned to flow upward, and the upward-flowing airflow flows upward through the gaps between the heat dissipation fins 4. The flow of the airflow carries the hot air outside the heat dissipation fins 4 to accelerate the movement and diffusion, thereby achieving the effect of accelerated heat dissipation. When it rains outdoors, rainwater flows into the steering guide groove 10 through the heat dissipation fins 4, and the rainwater in the steering guide groove 10 is discharged through the drainage hole groove 13 opened at the bottom of the rainwater collecting groove 12, so as to prevent rainwater from dripping onto the heat dissipation fan 11 through the special-shaped guide groove 9 and the heat dissipation guide disc 8 and causing damage to the heat dissipation fan 11.
