The electromagnetic compatibility problem and power supply power supply problem of transmission line of electricity on-line monitoring equipment.In order to meet engineering in practice to fiber grating
The requirement of composite insulator strain sensing performance, need to carry out a large number of experiments come between plug and grating strain transmission characteristic into
Row research.
And in the prior art for optical fiber composite insulator and preparation method thereof, fiber grating composite insulator includes core
Stick, plug are implanted into optical fiber, and grating is carved on optical fiber, and the one end of optical fiber containing optical fiber interface is drawn from plug.This method is to paste
Fiber grating is implanted in plug by method.The slot for being parallel to plug axis is opened in plug outer wall, is laid with an optical fiber in a bar groove,
Slot is filled and led up by filler, then carries out the installation of bulb and the injection of full skirt.This method can satisfy the requirement of sensing accuracy, together
When manufacturing method it is simple, be the best fiber arrangement method to optical fiber composite insulator basic research early period.
Fiber grating composite insulator strain sensing technology is needed to carry out and is sensed under different grating parameters, technology for applying
The research of performance.Therefore, fiber grating composite insulator needed for basic research early period is other than requiring manufacture craft simple,
It also needs to save time, cost-saving.However, the forming processes such as the installation of above method optical fiber composite insulator bulb, full skirt injection are cumbersome,
