Optical fiber insulator

Abstract

A kind of optical fiber insulator includes the optical fiber insulator element, whose characteristic is that, the said optical fiber insulator element has disk shape with a bit taper, setting up the stem part of the optical fiber along the vertex angle of the taper disk, the circumference border of the disk part has protruding edge. The optical fiber insulator that in this invention, solving the problem of high pressure creepage, has improved the usage power voltage greatly; The set of encapsulations structure optical fiber grating sensor matches with the encapsulation structure of electric accessory connection form, makes the detecting device not affect by illuminant ups and downs, component ageing, optical fiber bending, it can improve the check accuracy greatly.

Description

technical field [0001] The invention belongs to the technical field of optical fiber sensing, in particular to an optical fiber insulator for an optical fiber grating sensor. Background technique [0002] In the known monitoring technology, traditional electrical sensors are vulnerable to environmental humidity and electromagnetic interference in power systems, and because they are active devices, they cannot be used in flammable and explosive environments. Therefore, the industry continues to invent new measurement technologies to solve the difficult problem of temperature measurement in high-voltage power systems, such as infrared measurement, wireless measurement, optical fiber temperature detection system and fiber grating temperature detection system. More advanced is the fiber grating sensor. Fiber Bragg grating sensors are wavelength coded and are not affected by light source fluctuations, device aging, fiber bending, etc., so they have very h...
