[0016] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0017] According to the fan box transformer protection device of the embodiment of the present invention, the fan box transformer protection device includes a protective cover 1, a lock 3 and a guide mechanism. A rotating door 2 is arranged on the first side of the protective cover 1, and the rotating door 2 is pivotally connected to the protective cover 1. A heat dissipation port 4 is arranged on the protective cover 1. The lock 3 is located on the rotating door 2 to fix the rotating door 2 and the protective cover 1. The guide mechanism is located in the protective cover 1 to improve the heat dissipation effect. The protective cover 1 is used to protect the transformer. The lock 3 is used to lock the rotating door 2 to facilitate maintenance by operators and ensure that the rotating door 2 is closed at ordinary times. The guide mechanism is used to cooperate with the heat dissipation port 4 of the protective cover 1 to dissipate heat, reduce the internal temperature, facilitate the transformer to work at a suitable temperature, and reduce the hidden danger of transformer short circuit fire.

[0018] The fan box transformer protection device according to the embodiment of the present invention has the advantages of good safety and eliminating potential safety hazards of equipment.

[0019] In some embodiments, the fan box transformer protection device further includes a monitoring mechanism, which includes a temperature sensor and a humidity sensor. The temperature sensor and the humidity sensor are located in the protective cover 1 to monitor temperature and humidity data.

[0020] Specifically, the sensor can monitor the temperature and humidity data inside the protective cover 1 in real time. Through real-time monitoring, environmental changes can be discovered in time, and equipment failures caused by abnormal temperature and humidity can be prevented, thereby improving the reliability and stability of the equipment. Ensuring that the working environment of the transformer in the protective cover 1 is normal is conducive to maintaining the normal operation of the transformer.

[0021] In some embodiments, the air guiding mechanism includes heat dissipation fins and a heat dissipation fan. A plurality of heat dissipation fins are arranged corresponding to the heat dissipation port 4 , and the heat dissipation fan is arranged corresponding to the heat dissipation fins. The heat dissipation fins are connected to the transformer for heat transfer through a heat conduction pipe.

[0022] Specifically, the heat sink fins are connected to the transformer through heat pipes to effectively transfer heat to the heat dissipation port 4. The heat sink fins and the heat pipes are filled with a cooling medium, which may be water. The heat pipes transfer heat from the transformer to the heat sink fins, and the heat sink fan sends air to the heat sink fins to cool the heat sink fins, which can improve heat dissipation efficiency, reduce the operating temperature of the transformer, extend the service life of the equipment, and reduce failures caused by overheating.

[0023] In some embodiments, the fan box protection device also includes a filtering mechanism, which includes a dust net and a cleaning brush. The dust net is located at the heat dissipation port 4, one end of the cleaning brush is abutted against the heat dissipation fins, and the other end of the cleaning brush is transmission-connected to the driving member.

[0024] Specifically, the dustproof net can effectively prevent dust and debris from entering, and the cleaning brush regularly cleans the dust on the heat sink fins. This design keeps the heat sink 4 clean, prevents dust accumulation from causing the heat sink fins to have a reduced heat dissipation efficiency, and thus maintains the stable operation of the device. The driving member can be an electric push rod, a cylinder, etc. It can be understood that the driving member only needs to drive the cleaning brush to perform a linear reciprocating motion relative to the heat sink fins.

[0025] In some embodiments, the protective cover 1 includes an insulating layer, a heat insulating layer and a protective layer. The insulating layer is formed by mixing glass fiber and insulating resin. The heat insulating layer includes heat insulating filler. The protective layer is formed by mixing weather-resistant resin and glass fiber.

[0026] Specifically, the insulating layer provides good insulation effect for the protective cover 1, the heat-insulating layer is used to reduce the influence of external heat on the protective cover 1, and the protective layer is used to improve the structural strength of the protective cover 1 to avoid collision damage. The insulating layer can be made of epoxy resin, polyester resin or phenolic resin, etc. The glass fiber has excellent electrical insulation performance and mechanical strength. The mixture of the two ensures the insulation performance and mechanical properties of the insulating layer. The heat-insulating layer can be polyurethane foam, mineral wool or glass wool. The three have good heat-insulating properties to ensure the heat-insulating effect, reduce heat transfer and maintain internal temperature stability. The weather-resistant resin can be one of polycarbonate, polyimide, silicone rubber and polytetrafluoroethylene, all of which have good high and low temperature resistance and adapt to environmental influences. Glass fiber is used to enhance mechanical properties.

[0027] In some embodiments, a self-cleaning coating is coated on the protective layer, and the self-cleaning coating is a hydrophobic coating.

[0028] Specifically, the self-cleaning coating is arranged on the protective layer to reduce the deposition of water vapor and dust on the protective layer, making it easier to clean the protective layer, reducing the frequency of cleaning and maintenance, and lowering maintenance costs.

[0029] In some embodiments, the hydrophobic coating is polyacrylate, polyethylene glycol, or polytetrafluoroethylene.

[0030] Specifically, the above-mentioned material has good hydrophobic properties, can effectively prevent moisture from adhering, protect internal devices from moisture, and improve the reliability of the devices in humid environments.

[0031] In some embodiments, the fan box transformer protection device further includes a sealed base 5 , on which a sealing groove is provided, and the sealing groove is used to abut against the edge of the protective cover 1 .

[0032] Specifically, a sealing groove is provided on the sealed base 5, which is used to closely connect with the edge of the protective cover 1, thereby improving the sealing performance inside the protective cover 1, preventing the intrusion of external debris and moisture, and ensuring the safe operation of the equipment. The sealed base 5 raises the height of the transformer and the protective cover 1, which can prevent moisture from entering through the bottom of the protective cover 1, and the sealed base 5 can reduce the impact of external vibration on the equipment.

[0033] In some embodiments, a sealing strip is arranged between the protective cover 1 and the sealing groove to fill the joint.

[0034] Specifically, the sealing strip is used to fill the joints to ensure sealing. The sealing strip can be made of materials such as silicone rubber or polyurethane. The sealing strip has a certain elasticity and durability. The use of the sealing strip further improves the sealing performance of the protective device, reduces the impact of the external environment on the equipment, and improves the protection level of the equipment.
