Abstract

The invention discloses an internal high-temperature juxtaposed distributed optical fiber temperature sensor which comprises a temperature sensor body, an inner sleeve is arranged on the outer side of the temperature sensor body, an outer sleeve is arranged on the outer side of the inner sleeve, optical fibers are connected to the two ends of the temperature sensor respectively, limiting devices are arranged at the two ends of the outer sleeve, and the optical fibers are fixed in the limiting devices. Each limiting device comprises an adjusting frame, an adjusting cavity is formed in the adjusting frame, a first lead screw and a second lead screw are arranged in the adjusting cavity, the first lead screw and the second lead screw are connected through a coupler, threads on the first lead screw and the second lead screw are reverse threads, sliding blocks are in threaded connection with the outer sides of the first lead screw and the second lead screw, and movable rods are fixedly arranged on one sides of the sliding blocks. The end, away from the sliding block, of each movable rod penetrates through the adjusting cavity and extends out of the adjusting frame to be fixedly connected with the protection ring. The optical fibers are fixed outside the protection rings. The beneficial effects of the optical fiber temperature sensor are that the optical fiber is convenient to fix and disassemble, and convenience is brought to later overhaul and maintenance.

Description

technical field [0001] The invention relates to an optical fiber temperature sensor, in particular to a distributed optical fiber temperature sensor with internal high temperature and juxtaposition. Background technique [0002] In recent inverter boards, switching surge voltage due to the inductance of bus bars inside the inverter board increases due to high-speed switching operations. Therefore, it is important to mitigate this switching surge voltage. In order to reduce the inductance, it is effective to use a so-called interlayer bus bar in which a bus bar that makes the switching current flow to one end of the switching circuit for load control and a bus bar that makes the switching current flow out from the other end of the switching circuit The bus bars face each other through an electrically insulating material. The prior art is the technical solution adopted by the optical fiber temperature sensor with the patent notification number CN104335019A: the optical fiber ...
