The daily maintenance of low-voltage drawer cabinet is an important operation to ensure the normal operation of power system, ensure the normal power consumption 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 operation. Then, what problems should be paid attention to in the daily maintenance of MNS low-voltage drawer cabinet?
1. Temperature: temperature is an important way 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, recording the temperature change of the low-voltage drawer cabinet regularly and drawing the temperature change curve are also conducive to a deeper understanding of the power consumption and problems 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 key point of maintenance.
3. Air pressure: Generally speaking, the change of air pressure in conventional environment is not enough to affect the normal operation of low-pressure drawer cabinet, but the sudden change of air pressure or the air pressure in high altitude area may have a certain impact.
4. Color and smell: color and temperature will not directly affect the low-voltage drawer cabinet, but generally the low-voltage drawer cabinet after the fault will present the smell of electric burning and smoke, so for the diagnosis of the low-voltage drawer cabinet after the fault, color and smell are still very important reference materials.
Generally, in the circuit system after strict planning and planning, 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 changes in the voltage of upstream power plant / power grid, which will present a variety of security risks.
