本专利提供一种温度监视系统,它包括一种线圈形式的光管,该光管是沿被测结构以一定间隔缠绕的(3)。光管缠绕在外壳(1)内的一个线架(2)上,外壳通过一螺拴(4)固定在电缆上。 在线架(5)上和光管线圈(7)下面,可以装一个加热装置(6),并由电缆的杂散电流供电。在外壳(10)内沿上、下隔热板(13、14)装有一个光管联接盒(11)和一块钢板(12)。 This patent provides a temperature monitoring system comprising a light pipe in the form of a coil wound at regular intervals along the structure under test (3). The light pipe is wound on a bobbin (2) inside the shell (1), and the shell is fixed on the cable by a bolt (4). Under the bobbin (5) and under the coil (7), a heating device (6) can be installed and supplied with stray current from the cable. A light pipe coupling box (11) and a steel plate (12) are provided in the casing (10) along the upper and lower heat shields (13, 14).
