Description

Technical Field

[0001] This utility model relates to the field of transformer technology, and in particular to a transformer heat dissipation device. Background Technology

[0002] In power systems, transformers, as core equipment, generate a significant amount of heat during operation. Currently, many transformers primarily rely on heat dissipation fins for cooling. Heat dissipation fins utilize the principle of increasing surface area to dissipate heat from inside the transformer to the surrounding environment through natural or forced air convection. This cooling method can meet the transformer's heat dissipation requirements to a certain extent; under low load and suitable ambient temperature conditions, heat dissipation fins can maintain the transformer within a relatively stable operating temperature range.

[0003] However, relying solely on heat dissipation fins has significant limitations. With the continuous growth in electricity demand, transformer loads are increasing, leading to a substantial increase in heat generation. The heat dissipation efficiency of the heat dissipation fins cannot keep up with the rate of heat generation, causing the transformer's internal temperature to rise continuously. When a transformer operates at high temperatures for extended periods, it accelerates the aging of insulation materials, reduces their insulation performance, increases the risk of short circuits and other faults, and severely impacts the transformer's service life and operational reliability. Utility Model Content

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. In this utility model, temperature sensors are installed in both the upper and lower oil conservator and are electrically connected to the intelligent control panel.

The tops of the two upper connecting parts 13 are fixedly connected to the upper oil conservator. 14 Bottom; The connecting assembly includes a first connecting pipe 1, a second connecting pipe 2, a first connecting pump 4, a second connecting pump 10, and three hollow parts 3. The first connecting pipe 1 passes through the three hollow parts 3 near the rear end, and the second connecting pipe 2 passes through the three hollow parts 3 near the front end. Both the first connecting pipe 1 and the second connecting pipe 2 are connected to the three hollow parts 3. One end of the first connecting pipe 1 is fixedly connected to the top output end of the first connecting pump 4, and one end of the second connecting pipe 2 is fixedly connected to the top input end of the second connecting pump 10. Both the first connecting pipe 1 and the second connecting pipe 2 pass through the left side of the upper oil conservator 14. Both the first connecting pipe 1 and the second connecting pipe 2 are fixedly connected to and connected to the upper oil conservator 14. The bottom input end of the second connecting pump 10 and the bottom of the first connecting pump 4 are connected to the bottom of the first connecting pump 4. All output terminals are fixedly connected to and communicate with the top of the lower oil conservator 5; the transformer body includes a transformer shell 6, heat dissipation fins 15, two fixing parts 16, and multiple connecting posts 17. Heat dissipation fins 15 are provided at the front end of the transformer shell 6, and are fixedly connected to and communicate with the transformer shell 6. The two fixing parts 16 are fixedly connected to the bottom of the transformer shell 6. The bottoms of the multiple connecting posts 17 penetrate the top of the transformer shell 6, and the transformer shell 6 is fixedly connected to the connecting posts 17; the transformer heat dissipation device also includes an intelligent control panel 8 and two audible and visual alarms 7. The two audible and visual alarms 7 are fixedly connected to the left side of the intelligent control panel 8, and are electrically connected to the intelligent control panel 8. Panel 8 is fixedly connected to the bottom left side of transformer housing 6. First connecting pump 4 is electrically connected to intelligent control panel 8, second connecting pump 10 is electrically connected to intelligent control panel 8, and two temperature sensors are electrically connected to intelligent control panel 8. The right sides of two lower connecting parts 9 are fixedly connected to the left side of transformer housing 6, and intelligent control panel 8 is located between the two lower connecting parts 9. Two upper connecting parts 13 are fixedly connected to the top of transformer housing 6, and both upper connecting parts 13 are located to the left of multiple connecting posts 17. Second connecting pipe 12 penetrates the top of transformer housing 6, and first connecting pipe 11 penetrates the left side of transformer housing 6. Both first connecting pipe 11 and second connecting pipe 12 are connected to transformer housing 6.In the initial state, the operator sets the preset temperature values ​​for the lower oil conservator 5 and upper oil conservator 14 in the intelligent control panel 8 according to the normal operating temperature range of the transformer. Temperature sensors in the lower and upper oil conservators 5 and 14 continuously monitor the oil temperature and transmit the data to the intelligent control panel 8 in real time. When the transformer is running, if the oil temperature in the lower or upper oil conservator 5 rises due to increased load or other reasons, and the temperature exceeds the preset value, the intelligent control panel 8, upon receiving the signal from the temperature sensor, will immediately activate the first connecting pump 4 and the second connecting pump 10. The first connecting pump 4 pumps the oil from the lower oil conservator 5 out through the first connecting pipe 1. The oil flows along the first connecting pipe 1, penetrating... The oil flows through the three hollow components 3 at the rear end; simultaneously, the second connecting pump 10 pumps the oil in the upper oil conservator 14 out through the second connecting pipe 2. The oil flows through the three hollow components 3 at the front end. Since the hollow component 3 is divided into two parts in the middle, the oil entering the hollow component 3 from the first connecting pipe 1 flows back to the upper oil conservator 14 through the second connecting pipe 2 after flowing inside the hollow component 3; while the oil entering the hollow component 3 from the second connecting pipe 2 flows back to the lower oil conservator 5 through the first connecting pipe 1. In this way, a circulation loop is formed between the first connecting pipe 1, the second connecting pipe 2, and the hollow component 3. The flow of the oil and the heat exchange between the hollow component 3 and the air remove heat, thus achieving heat dissipation for the transformer. During the heat dissipation process, such as If the temperature sensor continuously monitors and detects that the temperature inside the lower oil conservator 5 and upper oil conservator 14 remains higher than the preset temperature for a certain period of time (this time can be set in the intelligent control panel 8 according to actual needs), this indicates that the current heat dissipation measures may not be effectively controlling the temperature, posing a potential risk. In this case, the intelligent control panel 8 will activate two audible and visual alarms 7, emitting an alarm sound and flashing lights. The alarm sound and flashing lights from the audible and visual alarms 7 will attract the attention of nearby personnel, notifying them to promptly inspect the device and investigate potential problems, such as whether the components of the heat dissipation device are working properly, or whether there are other faults in the transformer causing abnormal heat increase, so that timely measures can be taken to resolve the issue. To ensure the stable operation of the transformer, the lower connector 9 securely connects the lower oil conservator 5 to the left side of the transformer housing 6 throughout the entire operation process, providing support for the lower oil conservator 5; the upper connector 13 fixes the upper oil conservator 14 to the top of the transformer housing 6, ensuring the stability of the upper oil conservator 14. The first connecting pipe 11 passes through the left side of the transformer housing 6, and the second connecting pipe 12 passes through the top of the transformer housing 6. They are connected to the transformer housing 6, enabling effective connection and heat transfer between the heat dissipation device and the transformer body. The heat dissipation fins 15 at the front end of the transformer housing 6 also assist in heat dissipation under normal conditions, working together with other components of the heat dissipation device to maintain the normal operating temperature of the transformer.
