How to maintain the low-voltage power distribution cabinet?
The low-voltage power distribution cabinet can be used for power conversion and control. When the enterprise needs to distribute power, lighting and other power, this equipment will enter the enterprise's procurement catalog, and its segmentation ability is strong, the combination scheme is flexible, and it can be applied The range is very large.
Although this product has many advantages, the maintenance and maintenance of low-voltage power distribution cabinets should not be underestimated. It must be carried out in the case of power failure. Even if the equipment can operate normally, it needs to be maintained and repaired once a year.
For the maintenance of low-voltage power distribution cabinets, it is necessary to first check whether the entire line is unblocked, whether there is a line connection failure caused by poor contact, and whether some components will be damaged due to the heating of components in the working state? Is the connection of the terminal posts firm and reliable? Is there any corrosion phenomenon? Can the secondary circuit also remain open? Is the insulation performance of each part maintained well?
Check the mechanical part to ensure that the mechanical part can operate smoothly, the pulling is smooth, the locking is firm, the contacts maintain good contact, and the circuit breaker and contactor can work normally and stably.
In a twinkling of an eye, it is the end of March, and the rain in spring has increased. If the distribution box encounters water intrusion, what should I do?
First of all, when the meter box is flooded, it is necessary to turn off the power immediately to prevent a short circuit, otherwise it is easy to blow up. After the power is turned off, it is necessary to accurately find the leaking place and do a good job of sealing it.
In addition, after ensuring that all components are dried, power on and turn on each switch, and test and check one by one to eliminate hidden dangers. Also note that in the process of installing the meter box, it is necessary to form an S-bend in the line entering the meter box to prevent water from flowing back.
At the same time, the maintenance electrician also needs to regularly inspect the distribution box. If serious heating is found in the internal parts, the cause of the heating needs to be found out. If the wiring is found to be loose, it should be tightened in time. Clean in time to keep the inside of the distribution box clean and tidy.
