Control and regulation mode of electric heating belt
电伴热带用于管道绝缘通常选择双导体加热电缆，该电缆具有两个内芯。加热电缆应具有隐接技术，绝缘性能优异，强度高，屏蔽性强，屏蔽层应为全金属屏蔽，具有良好的柔韧性，有利于施工。此外，它应该具有卓越的防水和环保性能。
加热电缆的主管沿管道外壁敷设，加热电缆以直线或波浪形直线与管道平行安装。支管与管道平行安装，并位于管道下方或直线上。具体方法视现场情况而定，并应根据相关标准留有余量，以便于对该位置的管件进行维护。
每个电加热系统都应能够防止超高温造成的损坏。可以使用用于电加热的专用温度控制器，该控制器与温度传感器一对一连接，以控制加热电缆的启动和停止。
温度调节方法包括手动和自动调节，自动调节是指每个加热电缆单元，包括温度控制器、温度传感器、空气开关、交流接触器、加热电缆断路器监视器、工作状态显示、故障蜂鸣器报警和其他电路，以便观察、控制，并调整电加热的工作条件。
在工作条件下，温度传感器安装在加热的管道上，可以随时测量其温度。温控器将预设温度与温度传感器测量的温度进行比较，并通过加热电缆控制箱内的空气开关和交流接触器，及时切断和连接电源，以达到加热和防冻的目的。为了确保每条加热电缆的供电可靠性，每条加热电缆绝缘系统控制箱控制相同性质和材料的管道的温度。加热电缆绝缘系统控制箱内的每条加热电缆独立运行，并配有空气开关和漏电保护断路器。
