用于低温电气性能测试平台的温度控制系统

A temperature controlling system used for electrical property test at cryogenic temperature

随着空间技术的不断发展和超导技术的实用化,不同低温环境下绝缘材料的电气特性越来越受关注。针对低温环境中绝缘材料电气性能测试系统,文章基于Labview平台,采用闭环控制原理设计了一套温度控制系统。该系统能较精确稳定地实现对试验区域温度的控制,可以用于不同低温温度下绝缘材料的电气性能测试。

With the development of space technology and the practical application of superconducting technology, the electrical properties at different cryogenic temperatures attract more and more attention. As a basis for electrical performance test system of insulating materials at cryogenic temperature, a set of cryogenic temperature control system was designed by Labview in this paper. Based on closed - loop control theory, the temperature control system realized the temperature control accurately and stably in test zone. And it could be used testing the electrical properties of insulating materials at different cryogenic temperatures.
