What is the general fault of the distribution box? How to maintain it at ordinary times?

(1) Faults caused by electronic device materials in the distribution box:

① The operating instructions of the distribution box are quite different from the real technical data information.

② The management method of taking and storing the distribution box is not tightly closed.

③ The safety technical disclosure for the construction of distribution box project is not established, which has produced redundant restraining factors for the installation and application of distribution box, resulting in operation failure.

(2) Distribution box failure caused by project construction:

① The quality of the annotation materials of the distribution box is strictly controlled, which leads to potential safety hazards for safe operation.

② The installation and processing process is unqualified, such as incomplete cleaning of the box body.

③ The materials in the distribution box are unqualified.

④ The insufficient and insignificant setting of signs in the distribution box and the untimely settlement of the sealing of the distribution box in the wet and cold natural environment have left potential safety hazards for the operation of the distribution box.

(3) Failure of distribution box caused by improper maintenance of management methods of operating enterprises:

① It is not allowed to carry out maintenance inspection and testing on time.

② Faults caused by periodic precipitation, wind and snow, extreme heat exposure and other factors, such as; The foundation bolt of grounding device is rusted and loose.

(4) Distribution box failure caused by other reasons:

① For the temporary power consumption load, the medium and long-term calculation or the lack of careful statistical analysis can not be taken into account, resulting in overload operation of the distribution box and failure.

② The upper and lower wiring holes of electronic devices in the distribution box are not matched with the diameter and cross section of incoming and outgoing cables, resulting in potential safety hazards of the power supply system.

③ During the construction of works around the distribution box, other technical disciplines damage the control circuit of the power supply system, resulting in its short-circuit fault or grounding device, resulting in the failure of the distribution box.

How to maintain the distribution box

The distribution box manufacturer here must pay attention to the maintenance of the distribution box in the whole process of its normal application. It can only be maintained well, so that its service life can be increased and its greater characteristics can be brought into full play.

When the distribution box is in the whole process of application, it must be de dusted on time, mainly to ensure the cleaning of the distribution box. Secondly, it must check whether the connector in the box is firm and ensure the credibility of the wiring. If it is found that there is any problem, it must be repaired immediately. Secondly, it must immediately check whether there is precipitation or sand intrusion in the body. In the whole process of application, We must also eliminate this risk factor, otherwise, it is very easy to encounter problems.

According to the above interpretation, you have a good understanding of the maintenance knowledge of the distribution box. The distribution box must be inspected and maintained once a month, and the new projects that fail to pass the customs should be handled properly and relevant records should be made.
