Three Common Faults Of Stainless Steel Distribution Boxes
1. Faults caused by ambient temperature on stainless steel Power distribution cabinet
Friends who are engaged in the electrical industry should know that some low-voltage electrical products have certain restrictions on ambient temperature, and exceeding the limit range will cause faults. However, the main structure of stainless steel Power distribution cabinet cannot be without some low-voltage electrical appliances, such as fuses, AC contactors, residual current action protectors, etc. The upper limit of the ambient temperature of these low-voltage electrical appliances does not exceed 40℃; the average value of the ambient air temperature for 24 hours does not exceed 35℃; the lower limit of the ambient air temperature is not lower than -5℃ or -25℃. Once the environmental limit is exceeded, problems are likely to occur, so friends need to pay attention.
2. Stainless steel Power distribution cabinet product quality problems were very common in the past few years. Although most stainless steel Power distribution cabinet manufacturers now attach great importance to product quality, there are also some manufacturers that produce unqualified stainless steel Power distribution cabinet products, so friends need to pay attention to this.
3. Faults caused by improper selection of electrical appliances in stainless steel Power distribution cabinet
Due to the improper selection of the capacity of the AC contactor during manufacturing, the same capacity AC contactors were installed for different outgoing circuits, and the imbalance of the three-phase load was not taken into account. The current level of some outgoing contactors was not increased by one current level on the basis of the normal selection model, which led to the burning of the AC contactor during operation in the high temperature season in summer.
There are three common faults of stainless steel Power distribution cabinet. As long as we understand them from the beginning and pay attention to them when choosing to use them, these faults can still be avoided. Here we suggest that if you need stainless steel Power distribution cabinet in the future, you must choose stainless steel Power distribution cabinet with hard enough quality, so that you can use it with more confidence.
