[0035] Embodiment 3

[0036] Please refer to Figures 4-5 The utility model provides the following technical scheme:

[0037] The filtering mechanism 3 comprises a breather cover 301, a filter plate one 302, a sealing cover 303 and a valve plate 304, the breather cover 301 is fixedly connected to one side of the exhaust pipe 202, the inside of the breather cover 301 movably clamps the filter plate one 302, the outer surface of the breather cover 301 movably clamps the sealing cover 303, and the valve plate 304 is arranged in the inside of the exhaust pipe 202.

[0039] The breather cover 301 is arranged at the top of the bearing box 201, and the breather cover 301 is sealed when the sealing cover 303 is fixedly clamped with the breather cover 301.

[0040] The limiting strip 306 is slidingly inserted in the inside of the slot 205, and the filter strip two 307 is arranged in the inside of the slot 205.

[0041] Further need to be explained is that: firstly, the valve plate 304 is in a normally open state, the sealing cover 303 needs to be opened first, and then the valve plate 304 is closed, at this time, the door plate 101 can be opened for maintenance, and the external air is filtered through the filter plate one 302 and then enters the inside of the high-voltage frequency conversion cabinet main body 1 through the fan 204 and the air supply pipe 203, but the air pressure in the high-voltage frequency conversion cabinet main body 1 is greater than that outside the high-voltage frequency conversion cabinet main body 1, so when the door plate 101 is opened, the air in the high-voltage frequency conversion cabinet main body 1 continuously blows outwards to avoid the unfiltered gas outside entering the inside of the high-voltage frequency conversion cabinet main body 1.

[0042] Working principle: When a heat dissipation device for a high-voltage frequency converter is used, a door panel 101 is rotatably connected to one side of the high-voltage frequency converter cabinet body 1. A sealing strip 102 is provided on one side of the door panel 101. The sealing strip 102 facilitates the sealing of the interior of the high-voltage frequency converter cabinet body 1 when the door panel 101 is closed. An exhaust duct 104 and an air supply duct 105 are respectively provided at the top and bottom of the high-voltage frequency converter cabinet body 1. A heat dissipation mechanism 2 and a filter mechanism 3 are connected through the exhaust duct 104 and the air supply duct 105. The heat dissipation mechanism 2 and the filter mechanism 3 facilitate the heat dissipation of the high-voltage frequency converter inside the high-voltage frequency converter cabinet body 1.

[0043] When it is necessary to dissipate heat from the high-voltage frequency converter inside the main body 1 of the high-voltage frequency converter cabinet, the interior of the main body 1 of the high-voltage frequency converter cabinet is a sealed environment when the door panel 101 is closed. At this time, the air inside the main body 1 of the high-voltage frequency converter cabinet is drawn upward by the fan 204 and the exhaust pipe 202, and reaches the heat dissipation fins 206 for heat dissipation. The cooled air after passing through the heat dissipation fins 206 is then transported back into the interior of the main body 1 of the high-voltage frequency converter cabinet through the air supply channel 105. Finally, the air is drawn from the interior of the main body 1 of the high-voltage frequency converter cabinet by the fan 204 and enters the exhaust pipe 202 again through the exhaust channel 104, thus circulating. This device facilitates the heat dissipation of the high-voltage frequency converter inside the main body 1 of the high-voltage frequency converter cabinet.

[0044] When maintenance is required on the interior of the high-voltage frequency converter cabinet body 1, the valve plate 304 is normally open. The sealing cover 303 needs to be opened first, and then the valve plate 304 needs to be closed. At this time, the door plate 101 can be opened for maintenance. After the external air is filtered by the filter plate 302, it enters the interior of the high-voltage frequency converter cabinet body 1 through the fan 204 and the air supply pipe 203. However, the air pressure inside the high-voltage frequency converter cabinet body 1 is greater than that outside the high-voltage frequency converter cabinet body 1. Therefore, when the door plate 101 is opened, the air inside the high-voltage frequency converter cabinet body 1 continues to blow outward to prevent unfiltered external gas from entering the interior of the high-voltage frequency converter cabinet body 1. This device facilitates maintenance on the interior of the high-voltage frequency converter cabinet body 1.

[0045] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
