Abstract

The invention discloses a high temperature resistance annular encapsulation fiber bragg grating sensor applied to a switchgear. The sensor comprises a grating temperature sensing area and an optical fiber. The optical fiber comprises a main body optical fiber, a guide optical fiber and a pigtail, wherein the guide optical fiber and the pigtail are located on both ends of the main body optical fiber. The grating temperature sensing area is enclosed in a Teflon high temperature resistance casing. The guide optical fiber and the pigtail are enclosed by Teflon high temperature resistance paint cloth. The fiber bragg grating sensor is in an annular structure. The guide optical fiber and the pigtail extend out of the Teflon high temperature resistance casing. The sensor provided by the invention has the characteristics of convenient installation, accurate measurement and less later maintenance.

Description

technical field [0001] The invention belongs to the field of on-line monitoring equipment for smart grids, and relates to a high-temperature-resistant ring-shaped packaged optical fiber grating sensor for a switch cabinet. Background technique [0002] With the rapid development of power grid construction and the widespread use of power switchgear, the problems caused by the abnormal temperature of the static contacts inside the switchgear are also increasing. Therefore, the demand for temperature monitoring of the static contacts of new switchgear or existing switchgear is increasing. strong. Traditional optical fiber monitoring equipment generally has problems such as creeping static electricity and cumbersome installation, which leads to inaccurate measurement results. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present invention provides a high-temperature-resistant ring-shaped package fiber grating sensor for switc...
