Description

Technical Field

[0001] The utility model relates to the technical field of low-voltage switch cabinets, in particular to a low-voltage switch cabinet which is convenient for heat dissipation. Background Art

[0002] The low-voltage switchgear is a device that converts high-voltage electricity into low-voltage electricity by a transformer and then diverts the electricity to each household. The low-voltage switchgear generates heat when diverting electricity. When the temperature in the cabinet is too high, it will cause the cabinet to spontaneously combust, causing danger. At the same time, when the low-voltage switchgear is in use, dust and water vapor will accumulate in the switchgear, which will affect the connection of the circuit in the cabinet and easily cause short circuit incidents.

[0003] Patent document No. 201721278878.7 discloses a combined heat dissipation top cover and a low-voltage switch cabinet, including a combined heat dissipation top cover with two bottom plates and a top plate. The combined heat dissipation top cover is only used as a combined unit, and the number of combined heat dissipation top covers can be adjusted in time according to the width of the low-voltage switch cabinet, which greatly increases the applicability of the top cover. Although the low-voltage switch cabinet improves the applicability of the top cover to a certain extent, the improvement in heat dissipation efficiency is not high, and multiple heat dissipation top covers are provided, which increases the installation workload and is slightly cumbersome.
