It's known that our common household appliances (such as air conditioners and refrigerators) can't be exposed to the sun. Of course, too high temperature is bad. Can the distribution cabinet be exposed to the sun? The distribution cabinet contains many components and is mainly constituted by the circuit breaker, capacitor and gauge table, and most of them pertain to the electrical system. Dongfang Dahua has to remind you that as long as there is a problem with electricity, the change in temperature may make the distribution cabinet unable to operate normally 

　　Temperature will definitely affect the operation of the power distribution cabinet, whether it is high or low. Some components inside the power distribution cabinet are subject to use conditions, and their normal working conditions are specified accordingly: the upper limit of the ambient air temperature does not exceed 40 °C; The average temperature of the surrounding air of 24 degrees Celsius does not exceed 35 ° C; The lower limit of the ambient air temperature is not less than -25°C.

　　Many manufacturers' power distribution cabinets are running outdoors, it is not only directly irradiated by sunlight to produce high temperature, but also in operation itself will produce heat, so in the summer high temperature season, the temperature of the distribution cabinet box will reach more than 60 °C, the temperature at this time greatly exceeds the ambient temperature specified by the low-voltage distribution cabinet, thus causing the electrical components in the distribution cabinet box to overheat and fail.
