（即发热节数）与母线交叉联接，形成连续并联电阻，母线通电后，各并联电阻 发热，形成一条连续的加热带，这种并联电热带可以任意剪切，将开始发热部分 控制在需要伴热部分，利用冷端作为下次维修的备用线。恒功率电热带不充许叠 绕、交叉及夹在绝热层材料中间，避免造成电热带过热损坏， 串联型恒功率电热带：是一种由芯线作发热体的电热带，在具有一定电阻的 芯线上通过电流，芯线发出热：由于芯线单位长度的电阻和通过的电流，在整个 长度上是相等的，所以各处的发热量也是相等的，形成一条连续的、发热量灼匀 的电热带，不会像并联型电热带随着使用长度的增加造成尾端功率降低，串联型 恒功率电热带一般均按管线实际长度设计，并在出厂时加工成成品供应，施工现 场无需人工接线，安装时应严格按设计长度安装，过长或过短均会影响功率，不 得任意切制，也不允许叠绕、交叉及夹在绝热层中间，避免造成电热带过热损坏。 4、温控馨选型：温控器用于控制被伴热介质温度保持在设定湿度充许改动（温 差）的范围内工作。当设定允许温差改动越小，则采用温控器的精度越高，设定 允许温差浓动较大，则可采用精度较低的温控器，如果用在有防爆要求的场合， 还应选用防爆型温控器， 变功率电热带因有一定的自调控功能，一般情况下可不设温控器。但对介质 温度液动有严格要求的场合，如介质温度改动不应大于士℃时，也需要借助高 精度温控器调控，此时温度传感器安装在被控介质管过或设备的表面，如果用于 防冻，则应采用环境型温度传感器，安装在气温变化比较敏感的地方，如地下车 库出入口处，当气温低于5时，电气开关箱内电谦接通，与该电气开关箱连接 的所有电热带系统都通电开始工作，当气温高于5C时，电源切断，所有电热带 系统断电，停止工作，一个环境型温控券，可以控制一个小区城的电伴热防冻， 恒功率电热带不管用于防冻或保温，都必须设置温控器配合工作，且每个电 伴热系统均单独设立温控器和线传感器，以防超温损坏， 图名 图集号甘12 电伴热编制说明（一） 顶7
