Technical Field

[0001] This utility model belongs to the field of transformer oil level detection technology, and specifically relates to a transformer oil level detection device. Background Technology

[0002] Distribution transformers are crucial equipment in power systems, bearing the heavy responsibility of voltage transformation, power distribution, and transfer. Their normal operation is essential for ensuring the safe, reliable, and economical operation of the power system and the stability of power supply and consumption. Furthermore, distribution transformers are numerous and widely distributed throughout the country. Therefore, effectively preventing and reducing transformer failures or accidents is of paramount importance.

[0003] The oil level in a transformer directly affects its heat dissipation and insulation performance. An excessively high oil level can lead to increased internal pressure, while an excessively low level can cause poor heat dissipation or insulation damage. Therefore, monitoring oil level changes and ensuring it remains within a suitable range is crucial for the stable operation of the transformer. However, traditional methods require personnel to travel to the site to check the oil level gauge on the transformer's oil tank (marked with oil level lines) and manually read the reading to determine if the oil level exceeds the limit. This is not only cumbersome and inconvenient but also prone to significant errors, resulting in unsatisfactory performance. Summary of the Invention

The pulsed radar wave oil level gauge 1 uses a high-frequency oscillator as a microwave generator. The generator generates microwaves that are emitted downwards. When the microwaves encounter the liquid surface, they are reflected back. The distance to the material surface is calculated based on the time difference between the emitted wave and the reflected wave (i.e., the microwave pulse stroke). The pulsed radar wave method of measuring oil level has the following advantages: displacement-free, non-contact measurement, unaffected by temperature, pressure and gas, process pressure up to 40 bar, medium temperature up to 300℃, and is especially suitable for measuring the oil level of containers containing flammable, explosive, and highly corrosive media.

[0018] Furthermore, a microcontroller 8 is fixedly installed in the middle of the interior of the main unit 2. The microcontroller 8 is an STC89C52RC microcontroller, which is a low-power, high-performance CMOS 8-bit microcontroller with 8K bytes of system programmable Flash memory.

[0019] Furthermore, a rechargeable power supply 9 is fixedly installed on the bottom right side of the main unit housing 2, and the input terminal of the rechargeable power supply 9 is integrally connected to a power cord 19. The rechargeable power supply 9 is a rechargeable lithium battery. In use, the power cord 19 on the rechargeable power supply 9 can be connected to an external power source. Through the transformer element built into the plug of the power cord 19, the industrial power supply can be transformed to convert the industrial voltage into the safe low voltage used by this device to power the rechargeable power supply 9. At the same time, the rechargeable power supply 9 further powers the microcontroller 8, LED display 14, voice broadcaster 16, electromagnetic buzzer alarm 18, and pulse radar wave oil level gauge 1.

It adopts a hardware decoding method, which further ensures the stability and sound quality of the system. Its compact size better meets the needs of embedding in other products.

[0023] Furthermore, an installation groove 17 is provided on the upper right side of the cover 10. An electromagnetic buzzer alarm 18 is fitted inside the installation groove 17. The electromagnetic buzzer alarm 18 is mainly composed of an oscillator, an electromagnetic coil, a magnet, a vibrating diaphragm, and a housing.

This data is then transmitted to the microcontroller 8 for analysis and processing, and further displayed on the LED display 14. When the oil level exceeds the limit, the voice broadcaster 16 and the electromagnetic buzzer alarm 18 are automatically triggered. The voice broadcaster 16 provides a voice reminder of the current value, and the electromagnetic buzzer alarm 18 provides an alarm reminder, promptly informing and reminding staff to handle the situation. The oil level detection is accurate, efficient, labor-saving, and convenient.
