摘要
近几年来被广泛使用的电热地面辐射采暖系统,其电热缆被埋于地面下,若有故障,不容易找到故障点。电热缆故障测试系统是为电热缆故障检测而设计的一套专用测试系统,文中主要介绍了系统硬件电路的设计和实现方法,并详细阐述了测试原理。实际测试表明,该系统工作可靠,能够精确找到埋于地下的电热缆的短路和断路的故障点。
In recent years, the electrical heating cable breakdown testing system is used widely. Its electrical heating cable is under the floor, and it is not essy for us to find the cable breakdown. The electrical heating cable breakdown test system is specially designed for testing cable breakdown. The measure of hardware design and realization is mainly discussed. The paper also presents the theory of testing in detail. In praitical application, the system shows stable, and it can test conductor interrupted and conductor short-ciucuit in electrical heating cable accurately.
