Abstract

Provided is a power transmission state evaluating system based on an optical fiber composite insulator. The power transmission state evaluating system based on the optical fiber composite insulator comprises the optical fiber composite insulator, an optical fiber composite insulator state sensing main machine, a monitoring data transmitting device and an optical fiber composite insulator state monitoring main station. The connection structure of the power transmission state evaluating system is that the optical fiber composite insulator on a power transmission line is connected with the optical fiber composite insulator state sensing main machine installed on a pole tower through an optical fiber, and the monitoring data transmitting device can transmit the optical fiber composite insulator power transmission states to the optical fiber composite insulator state monitoring main station in a GPRS mode. The power transmission state evaluating system can transmit insulator operation states backwards in real time, solves the problems that traditional manual polling is long in period, poor in polling effectiveness and the like, and can well guarantee safe operation of power transmission safety.

Description

technical field [0001] The invention belongs to the field of high-voltage transmission line monitoring, and relates to a power transmission state evaluation system based on an optical fiber composite insulator. Background technique [0002] As the use time of insulators increases, their mechanical strength and pollution flashover resistance will also decrease. However, most of the high-voltage transmission lines are distributed in inaccessible mountainous areas, and it is difficult to inspect insulators. At present, there is still no effective The method can detect the insulator's shape defect, internal stress change, leakage current intensity and other characteristics. Contents of the invention [0003] In order to overcome the shortcomings of existing insulator operating state detection, the present invention proposes a power transmission state evaluation system based on optical fiber composite insulators, which realizes real-time monitoring of damage, deformation, and t...
