Specific embodiment
In order to be illustrated more clearly that the technical solution of the utility model, the utility model is made into one below in conjunction with accompanying drawing
Step description.
Embodiment of the present utility model 1 as Figure 1-3：
A kind of low-tension switch cabinet, including casing 1, air switch 2, plug-in strip 3 and sunshade 4.Wherein, the air switch 2
All it is installed in casing 1 with plug-in strip 3, and sunshade 4 is installed on the top of casing 1, for blocking the sunlight spoke of open air to casing 1
Penetrate.The side wall of the casing 1 is provided with louvre 12, the casing 1 and is provided with radiator fan 11 and ambient temperature sensor 13.Institute
State ambient temperature sensor 13 to electrically connect with radiator fan 11, the temperature mistake in casing 1 is detected when ambient temperature sensor 13
Gao Shi, radiator fan 11 starts, to the air blast of casing 1, it is ensured that the radiating and cooling of casing 1.
