How to check if the electric heating belt is not hot
电伴热管道保温已成为许多行业管道、储罐和其他设备防冻保温的产品。然而，在运输和安装过程中，或现场非标准安装可能会导致产品问题。如何检测电伴热带是否不热？
我们经常使用万用表来确定电伴热带是否损坏。万用表主要用于测量电伴热带的电阻值。电阻值用于判断电伴热带的好坏以及是否损坏。使用万用表检测电伴热带分为以下步骤：
1、收到电伴热带后，需要使用万用表检查电伴热带是否会因运输而损坏；
2、安装后，应对电伴热带和系统进行测试，以确保整个系统在外绝缘施工前能够正常工作；
3、电伴热系统应在外保温层安装后进行测试，以确保保温层的施工不会损坏电伴热带。
在实际测量中，低压为DC500 V，高压为DC1000 V。无论系统多长，每个伴热电路的绝缘电阻至少为10 Mohm。应在每个电伴热带导体与保护编织层之间以及保护编织层与接地管之间测量带有保护编织层和外护套的电伴热带。无编织带和保护套管的电伴热带：测量电伴热带的每根电源线与接地管或隔热接地钢套管之间的距离。
以上是对电伴热带万用表检测的简要介绍。您对万用表检测和电伴热带系统正常运行的确定有一定的了解。在实际检测中，应由电工操作，并对电路有一定的了解，以确保测量的正确操作。
