The daily maintenance of low-voltage drawer cabinet is an important work to ensure the normal operation of power system, ensure the normal use of power grid and extend the service life of low-voltage drawer cabinet. Therefore, the daily maintenance of low-voltage drawer cabinet is a very important work. Then, what problems should be paid attention to in the daily maintenance of MNS low-voltage drawer cabinet?
1. Temperature: temperature is an important means to understand the load of power supply and power supply circuit. It is very important to monitor the temperature when overhauling the low-voltage drawer cabinet. In addition, by regularly recording the temperature change of the low-voltage drawer cabinet and drawing the temperature change curve, it is also conducive to a deeper understanding of the power consumption and faults in the power supply network of the low-voltage drawer cabinet.
2. Humidity: humidity is the insect bite parameter that affects the service life of the internal structure of low-voltage drawer cabinet. Too high humidity will not only bring the risk of internal high-voltage arc, but also produce certain metal corrosion, so it is also the focus of maintenance.
3. Air pressure: Generally speaking, the change of air pressure in the conventional environment is not enough to affect the normal operation of the low-pressure drawer cabinet, but the sudden change of air pressure or the air pressure in high altitude areas may have a certain impact.
4. Color and smell: color and air temperature will not directly affect the low-voltage drawer cabinet, but generally after the failure of the low-voltage drawer cabinet will appear electric burning smell and smoke, so for the diagnosis of the low-voltage drawer cabinet after the failure, color and smell are very important reference materials.
Generally, in the circuit system that has been strictly planned and designed, MNS low-voltage drawer cabinet only needs to be overhauled according to the normal cycle, but after the internal and external super large changes, it must be overhauled comprehensively, such as earthquake, super large voltage changes of upstream power plant / power grid, etc., all kinds of potential safety hazards will appear.n
