110kv Composite Insulator Implanted with Fiber Bragg Grating

Abstract

The invention relates to a high-voltage insulator, especially a 110kV composite insulator implanted with an optical fiber grating into an insulator core rod, which can automatically monitor the stress and temperature of the insulator in real time and on-line; the invention includes optical fiber, white Sleeve, metal soft sleeve, outdoor armored sleeve and core rod; grating is installed on the optical fiber; a white sleeve is sleeved on the pigtail part of the optical fiber, and a metal soft sleeve is sleeved on the outside of the white sleeve. An outdoor armored casing is sleeved on the outer side of the metal soft casing; stepped grooves including groove 1, groove 2 and groove 3 are engraved on the mandrel; the metal flexible casing is fixedly connected in groove 1, and the metal flexible casing covers The termination section of the area coincides with the right end face of slot 1; the white sleeve is fixedly connected in slot 2, and the termination section of the coverage area of ​​the white sleeve coincides with the right end face of slot 2; the part of the optical fiber that is not sleeved is fixedly connected in slot 3; fixed The outside of the core rod of the good fiber is sealed with a sealant.

Description

technical field [0001] The invention relates to a high-voltage insulator, in particular to a 110kV composite insulator implanted with an optical fiber grating into an insulator core rod, which can automatically monitor the stress and temperature of the insulator in real time and on-line. Background technique [0002] The performance of high-voltage insulators, especially the mechanical and insulating properties, has a serious impact on the safe operation of the power system. Therefore, regular monitoring of the mechanical strength and insulating properties of insulators is required. The traditional insulator monitoring method is based on the requirements of DL / T864-2004, inspections are carried out every 1-2 months, and insulators are taken from the tower every 3-5 years and sent to the laboratory for performance inspection. This sampling inspection method has the disadvantages of high work intensity, risk of boarding the pole, and long time consumption. The entire monitori...

Problems solved by technology

This sampling inspection method has the disadvantages of high work intensity, risk of boarding the pole, and long time consumption.

The entire monitoring process is time-consuming, labor-intensive, and the measurement data is scattered, and it is impossible to track the performance of the insulator over time. Therefore, it is very important for the safe operation of the power system to make a high-voltage insulator that can be monitored in real time and online.
