低压抽屉柜日常检修的问题有哪些?

发布时间:2021-10-03 来源:http://www.tongyuhengcheng.com/ 浏览量:

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 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·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 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·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 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·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 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.
一般在经过严格规划和设计的电路系统中,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安全隐患。
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.
