温控伴热电缆温度采集与控制系统的研究

Gather the research with the control system in temperature-controled companion's hot cable data

介绍了利用伴热电缆本身PTC热敏材料所具有的自调控温能力,再配上温度测控系统,从而克服由于受到传热因素的影响使PTC伴热电缆控温精度不高,启动电流过大的问题,提高控制等级和精度,节约电能。该成果可广泛应用于石油、化工、管道传输、公路机场积雪、农产品生产、民用等行业中。

This text introduction utilize companion hot cable own PTC temperature sensing what material have transfer the ability of controlling the temperature by oneself, mix temperature observe and control system , thus overcome because conduct heat into to is it make PTC accompany hot cable control the temperature precision to be high to influence factor and then, start the too big problem of the electric current, improve and control the grade and precision , economize the electric energy. This achievement can apply extensively petroleum, chemical industry , pipeline are transmitted, the snow , agricultural product of highway airport are produced, civil etc. in the trade.
