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. 

　　Analysis of the reasons for the pile attack of outdoor power distribution cabinets Heating furnace distribution cabinets are in use conditions are relatively bad, a few are outside the rape, the line should be forbidden to be cool. The tempering of the low temperature and cold natural environment slows down the aging of the line. In winter, there will be a short circuit in the power distribution cabinet, causing the CPU module, analog input module and other components to be burned. Causing hindrance to oilfield production, the cause of the shortcomings of the distribution cabinet is the second strike, these lightning waves into the distribution cabinet, can occur up to millions of volts of voltage, the destructive force is commensurate. It directly causes any harm to the insulator protecting the equipment in the distribution cabinet, so that the insulator in the distribution cabinet is damaged.

　　The power distribution cabinet is normally installed outdoors, although some of it is installed indoors, and some workers often react that your distribution cabinet shell outside the plant sometimes has the feeling of electric shock, and ask us whether we have achieved results, maybe the distribution cabinet is aging. In fact, it is still relatively convenient to check, and it is necessary to find out what the cause is when there is a leakage, such as Xu Caihao to prescribe the right medicine, the leakage can be large or small, and it is certainly not a big achievement to deal with it as soon as possible. In fact, the scene of power leakage may be caused by the ground wire not connected well or caused by lightning strikes, such as the possibility of stimulating power leakage, not the aging of the equipment shell, but the aging of the estimated wire may also be there, so to check it, is not grounded or the performance of wire aging.
