When the low-voltage withdrawable switch cabinet with line protection function is used, the semiconductor refrigeration plate 4 is connected to an external power supply, and the semiconductor refrigeration plate 4 is cooled. The cold air of the semiconductor refrigeration plate 4 enters the switch cabinet body 1 through the cooling plate 5 and the cooling fan 6 for cooling treatment, and the heat generated by the semiconductor refrigeration plate 4 itself will be taken out through the cooling fan 3.

[0033] Working principle: When the low-voltage withdrawable switch cabinet with line protection function is used, the semiconductor refrigeration plate 4 is connected to an external power supply, and the semiconductor refrigeration plate 4 is cooled.
