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

At the moment of choosing high voltage distribution cabinet, it's necessary to follow the basic principle of safety, practicality and simplification and strive to choose high voltage distribution cabinet economically, scientifically and reasonably. At the time of choosing a low voltage distribution cabinet, due to the wide variety and different performances, it's necessary to determine the main technical parameters of the low voltage distribution cabinet and low voltage distribution cabinet requirements against main components for optimization selection. The main causes of power supply failures of the distribution cabinet are as follows

You can know that the distribution cabinet industry and the daily necessities in life are needed anywhere. A unit powered by electricity needs the distribution cabinet, and there is a distribution cabinet in the family, school and enterprise. Although the size of these distribution cabinets may be different, their role cannot be ignored. What is the role of the distribution cabinet?

The causes of lightning strokes on outdoor distribution box (cabinet) and factors for distribution cabinet lightning strokes are as follows: the working environment of the heating furnace distribution cabinet in use is relatively harsh, most of them are outdoor, and the lines are subject to the test of the intense heat of summer, high temperature and cold natural environment. Such environment also accelerates the aging of the line. Especially in summer, with many thunderstorms, the short circuit happens to the distribution cabinet and the major elements (such as CPU module and analog input module) are burnt, resulting in circuit failure.

The distribution box shall be regularly dedusted to keep the distribution box clean. Periodically check whether the connectors in the distribution box are firm to ensure the reliability of the wiring. Check whether the action of the related switch is normal, and replace the abnormal switch timely. Check whether there is rainwater or sand and dust intrusion into the box, and eliminate these dangerous factors.
