1·溫度：溫度是了解供電和供電電路負荷情況的重要手段，在檢修低壓抽屜柜時(shí)，對溫度的監控可以說(shuō)是非常重要的，另外通過(guò)定時(shí)記錄低壓抽屜柜的溫度變化，繪制溫度變化曲線(xiàn)也有利于更深入的了解低壓抽屜柜供電網(wǎng)絡(luò )內的用電和故障情況。
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 during the maintenance of low-voltage drawer cabinet. In addition, by regularly recording the temperature change of low-voltage drawer cabinet and drawing the temperature change curve, it is also conducive to a deeper understanding of the power consumption and fault in the power supply network of low-voltage drawer cabinet.
2·濕度：濕度是影響低壓抽屜柜內部結構使用壽命的蟲(chóng)咬參數，過(guò)高的濕度不僅會(huì )帶來(lái)內部高壓電弧的風(fēng)險，同樣也會(huì )產(chǎn)生一定的金屬腐蝕作用，因此也是檢修的。
2. Humidity: humidity is an insect bite parameter affecting 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·氣壓：一般來(lái)說(shuō)常規環(huán)境的氣壓變化不足以影響低壓抽屜柜的正常運行，但是突變的氣壓或者高海拔地區的氣壓可能就有一定的影響了。
3. Air pressure: Generally speaking, the change of air pressure in conventional environment is not enough to affect the normal operation of low-voltage drawer cabinet, but sudden change of air pressure or air pressure in high altitude areas may have a certain impact.
4·顏色和氣味：顏色和氣溫并不會(huì )直接影響低壓抽屜柜，但是一般在故障后的低壓抽屜柜會(huì )出現電灼燒的氣味和煙塵，因此對于故障后的低壓抽屜柜的診斷，顏色和氣味還是非常重要的參考資料。
4. Color and smell: color and temperature will not directly affect the low-voltage drawer cabinet, but generally, the smell and smoke of electric burning will appear in the low-voltage drawer cabinet after fault. Therefore, color and smell are still very important reference materials for the diagnosis of low-voltage drawer cabinet after fault.
一般在經(jīng)過(guò)嚴格規劃和設計的電路系統中，低壓抽屜柜只要按照正常的周期檢修即可，但是對于內外部超大型變化后，一定要對低壓抽屜柜進(jìn)行檢修，比如地震、上游電廠(chǎng)/電網(wǎng)的電壓超大變化等，都會(huì )出現各種各樣的隱患。
Generally, in the circuit system that has been strictly planned and designed, the low-voltage drawer cabinet can only be overhauled according to the normal cycle. However, after the internal and external super large changes, the low-voltage drawer cabinet must be overhauled comprehensively, such as earthquake, super large voltage changes of upstream power plant / power grid, etc., there will be a variety of potential safety hazards.
