7. Innovation: The high-end decorative paintings are made of porcelain crystal. The picture quality is high-definition and will never fade. The effect is very good. It is recommended to look for streaking meter boxes to enjoy the effect.

2. What are the common faults of distribution boxes?

1. Failures caused by the influence of ambient temperature on low-voltage electrical appliances. The low-voltage electrical appliances in the distribution box are composed of fuses, AC contactors, residual current action protectors, capacitors and meters. The upper limit of the ambient air temperature does not exceed 40°C; the 24-hour average of the ambient air temperature does not exceed 35°C; the lower limit of the ambient air temperature is not lower than -5°C or -25°C. The distribution box transformed by the rural power grid operates outdoors. It is not only exposed to direct sunlight and generates high temperatures, but also generates heat during operation. Therefore, in the high temperature season of midsummer, the temperature inside the box will reach above 60°C. At this time, The temperature greatly exceeds the ambient temperature specified for these appliances.

2. Failures caused by product quality. During the transformation of rural power grids, due to the large number of distribution boxes required and the short construction period, the distribution box factory needed the supply of low-voltage electrical appliances in a hurry and in large quantities. As a result, the requirements for product quality were not strict, resulting in Some products malfunctioned shortly after being put into operation. For example, some types of AC contactors cannot operate due to the burnt out contactor closing coil shortly after the distribution box is put into operation.

3. Failure caused by improper selection of electrical appliances in the distribution box. Due to improper selection of AC contactor capacity during manufacturing, AC contactors of the same capacity were installed on different outgoing circuits, and the unbalanced situation of the three-phase load was not taken into account, and the current level of some outgoing contactors failed to be within the normal range. Based on the selected model, increase the current level selection.

4. For distribution boxes with a distribution transformer capacity of 100kV·A and above, consideration should be given to installing a temperature control relay (JU-3 or JU type) near the side wall of the heat dissipation window in the box. -4 ultra-small temperature relay) and axial flow fan are installed on the box on the left side above the control electrical panel, so that when the temperature in the box reaches a certain value (such as 40°C), the exhaust fan can be automatically started to forcibly discharge the heat to dissipate heat from the box.

There are many styles of decorative paintings for accessories, which can make home decoration more colorful. The distribution box is no longer dull through decorative paintings, and the safety of electricity consumption is increased.
