detailed description

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

Please refer to Figure 1, the utility model provides a technical solution: a temperature-controlled low-voltage power distribution cabinet, including a power distribution cabinet body 3 and a compressor 2, and the bottom of the power distribution cabinet body 3 is provided with a shock-absorbing base 1 , and a control panel 6 is installed on the upper right side of the cabinet body 3 of the power distribution cabinet, and a dehumidifier 15 is installed below the control panel 6.
