Abstract
Description
Technical Field
[0001] The present application relates to the technical field of monitoring power equipment, and in particular to a transformer and circuit breaker monitoring device. Background Art
[0002] Transformers and circuit breakers play a vital role in power systems. As core equipment in power systems, they play an important role in ensuring safe and stable operation. With the continuous expansion of power systems and technological advancements, attention to the health of power equipment is increasing. Effective monitoring equipment can not only detect and prevent faults in a timely manner, improving system reliability, but also reducing the risk of accidents. Especially under long-term high-load operation conditions, timely heat dissipation becomes a key factor in ensuring the normal operation of power equipment. In recent years, with the development of smart grids, higher requirements have been placed on transformer and circuit breaker monitoring technology, promoting the design and application of related monitoring devices.
[0003] Existing transformer cooling devices primarily fall into two categories: air cooling and liquid cooling. Air cooling primarily utilizes fans or other similar components to accelerate air circulation and remove heat generated by the transformer; liquid cooling, on the other hand, removes heat through circulating coolant. Both cooling methods are widely used in practice, but each faces its own limitations. For example, air cooling is significantly affected by ambient temperature and struggles to achieve efficient heat dissipation under high loads. While liquid cooling is more adaptable to high-temperature environments, its high sealing requirements mean that leaks or blockages in the cooling system can compromise overall heat dissipation performance.
[0004] Regardless of the cooling method used in the aforementioned technologies, effective prevention of dust and other impurities is crucial in practical applications. Dust accumulation not only leads to poor contact between heat sinks, reducing heat transfer efficiency, but also causes a series of negative effects, including a decrease in insulation resistance. Especially for transformers operating under harsh conditions, dust particles can easily enter the equipment with airflow and adversely affect electronic components. Therefore, designing a monitoring device that is both efficient in heat dissipation and dust-resistant is particularly urgent. Utility Model Content
[0005] In order to overcome the above problems, the present application provides a transformer and circuit breaker monitoring device.

The coolant can flow in the cooling pipe and can cool the box. Compared with the related art, the present application injects coolant into the cooling pipe through the cooling element, thereby effectively extending the working life of the transformer and circuit breaker. At the same time, the dustproof component can effectively prevent external dust from entering the box, avoiding the reduction of heat dissipation efficiency and short circuit of electrical components caused by dust accumulation, and can achieve both efficient heat dissipation and good dustproof ability for the box.
[0010] In a specific embodiment, the dustproof component includes a filter screen, the filter screen is located at the dustproof port, and the filter screen is detachably connected to the box body.
[0011] By adopting the above technical solution, the filter is located at the dustproof port and is detachably connected to the box body, which effectively blocks external dust and facilitates regular maintenance and replacement, thereby better realizing the dustproof function.
[0012] In a specific embodiment, the filter screen adopts a three-layer design, and each layer has a certain thickness.

When the dust in the dust box 416 needs to be cleaned, the drive motor 422 drives the cam 423 to rotate, and the smaller end of the cam 423 can continuously hit the bottom of the dust box 416, causing the bottom of the dust box 416 to vibrate, which is convenient for collecting dust.
[0046] The implementation principle of a transformer and circuit breaker monitoring device in an embodiment of the present application is as follows: when the transformer and the circuit breaker are working, the temperature sensor can measure the temperature inside the box 1. When the temperature inside the box 1 is higher than the preset value, the temperature sensor transmits a signal to the cooling pump, and the cooling pump performs a circulating cooling operation, thereby cooling the box 1; at the same time, the temperature sensor transmits a signal to the dust extraction fan 413, and the dust extraction fan 413 sucks the dust into the second pipe 415 through the first pipe 411 and the dust extraction head 412, and then enters the dust collecting box 416 through the second pipe 415, and draws part of the heat in the box 1 through the first pipe 411 and the second pipe 415 to the dust collecting box 416, thereby realizing secondary cooling of the box 1.
