[0002] High and low voltage switchgear is a device used to connect high and low voltage cables. The high voltage is transmitted through the high voltage cabinet, and then stepped down by the transformer to the low voltage cabinet. The low voltage cabinet is then transferred to the distribution boxes of each power user. The switchgear is usually composed of a series of electrical equipment such as circuit breakers.

[0003] A Chinese patent discloses a high and low voltage switch cabinet with patent number CN202222766699.5. The utility model can achieve the effect of real-time early warning measurement of the internal temperature of the high and low voltage switch cabinet body and automatic heat dissipation through the mutual use of the high and low voltage switch cabinet body, smoke detector, sound and light alarm, heat dissipation holes, temperature sensor and fan blades.

[0004] However, there are still some problems in actual use:

[0005] The drive motor and fan blades for heat dissipation are arranged on one side of the cabinet near the bottom, and the drive motor is directly fixed to the ventilation duct through the second support plate, and the ventilation duct is directly fixed to the cabinet. Therefore, the heat dissipation wind blown out by the fan blades driven by the drive motor basically only stays in the bottom area of ​​the cabinet. The area located higher in the cabinet cannot be blown by the heat dissipation wind, thereby reducing the heat dissipation effect of the fan blades, which is not conducive to better heat dissipation inside the cabinet. Therefore, we provide a high and low voltage switch cabinet structure that is easy to dissipate heat. Summary of the invention
