低压抽屉柜日常检修是确保电力系统正常运行，保证电网正常用电和延长低压抽屉柜使用寿命的重要工作，因此低压抽屉柜日常检修是一项非常重要的工作，那么，
MNS低压抽屉柜日常检修要注意哪些问题呢？
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·温度：温度是了解供电和供电电路负荷情况的重要手段，在检修低压抽屉柜时，对温度的监控可以说是非常重要的，另外通过定时记录低压抽屉柜的温度变化，绘制温度变化曲线也有利于更深入的了解低压抽屉柜供电网络内的用电和故障情况。
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·湿度：湿度是影响低压抽屉柜内部结构使用寿命的虫咬参数，过高的湿度不仅会带来内部高压电弧的风险，同样也会产生一定的金属腐蚀作用，因此也是检修的重 点。
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·气压：一般来说常规环境的气压变化不足以影响低压抽屉柜的正常运行，但是突变的气压或者高海拔地区的气压可能就有一定的影响了。
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·颜色和气味：颜色和气温并不会直接影响低压抽屉柜，但是一般在故障后的低压抽屉柜会出现电灼烧的气味和烟尘，因此对于故障后的低压抽屉柜的诊断，颜色和气味还是非常重要的参考资料。
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.
一般在经过严格规划和设计的电路系统中，MNS低压抽屉柜只要按照正常的周期检修即可，但是对于内外部超大型变化后，一定要对低压抽屉柜进行全 面检修，比如地震、上游电厂/电网的电压超大变化等，都会出现各种各样的隐患。
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
