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,對溫度的監控可以說是非常重要的,另外通過定時記錄低壓抽屜柜的溫度變化,繪制溫度變化曲線也有利于更深入的了解低壓抽屜柜供電網絡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咬參數,過高的濕度不僅會帶來內部高壓電弧的風險,同樣也會產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:一般來說常規環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:顏色和氣溫并不會直接影響低壓抽屜柜,但是一般在故障后的低壓抽屜柜會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.
一般在經過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行檢修,比如地震、上游電廠/電網的電壓超大變化等,都會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.
