江苏春晨电缆有限公司生产供应CCHR起重机手柄电缆,电流热效应的弊

The Disadvantage of Current Thermal Effect

当大电流通过电导线而导线又不够粗时,就会产生大量的热量,破坏导线的绝缘性能,从而导致多条导线的线路出现短路,引发电气火灾。为了避免导线过热,有关部门对各种不同截面积的电导线缆规定了最大允许电流(安全电流)。供应CCHR起重机手柄电缆

When the large current passes through the conductor and the conductor is not thick enough, it will produce a lot of heat, which will damage the insulation performance of the conductor, and lead to short circuit of many conductor lines, and lead to electrical fire. In order to avoid overheating of conductors, the departments concerned stipulate the maximum allowable current (safe current) for all kinds of conductors and cables with different cross-sectional areas.



短路电流的热效应是酿成电气火灾的主要原因。因为短路电流很大,通常为工作电流的几倍至几十倍,足以引燃短路点周围的可燃物质,从而导致电气火灾的发生。现在电工在一些电路设计及施工中,采取电气火灾监控系统来尽量减少和控制此类事件的发生及影响。

The thermal effect of short circuit current is the main cause of electric fire. Because the short circuit current is very large, usually several to several dozen times of the working current, it is enough to ignite the combustible material around the short circuit point, which leads to the occurrence of electrical fire. At present, in some circuit design and construction, electrical fire monitoring system is adopted to minimize and control the occurrence and impact of such incidents.



一些大功率电子元器件在工作中要发热,电动机、变压器等在运行中会产生升温,这也是电磁热效应引起的,温度过高会危机这些设备的安全,所以一般要想方设法采取散热措施,以便延长设备的使用寿命。

Some high-power electronic components need to heat up in their work. Electric motors, transformers and so on will generate temperature rise in operation. This is also caused by electromagnetic heat effect. Excessive temperature will endanger the safety of these devices. Therefore, it is generally necessary to take heat dissipation measures in order to prolong the service life of the equipment.
