Embodiment Construction

[0027] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0028] The invention provides a method for monitoring the external damage of transmission line towers by laser and microwave linkage. figure 1 , according to the following steps to carry out the breakout detection:

[0029] S1: Determine the laser emitting and receiving distance of the laser microwave double-detection detector according to the sag height of the transmission line between the transmission line towers and the safety distance of the transmission line.

[0030] The conductor sag height of the transmission line between the transmission line towers can be calculated by the altitude difference between the towers and the span direction. The horizontal distance between the two suspension points of the overhead line in the plane parallel to t...

Abstract

The invention discloses a method and system for monitoring the external breakage of a power transmission line pole through laser and microwave linkage in the electrical engineering field. The method comprises the steps: installing a laser and microwave transmitter at the top of the pole, installing a laser and microwave dual-technology detector around the pole, and performing the external breakagedetection according to the following steps: determining a laser transmitting and receiving distance of the laser and microwave dual-technology detector according to a conductor sag height of the power transmission line between the power transmission line poles and a safety distance of the power transmission lines; determining the microwave radiation radius of the laser and microwave transmitter through the laser transmitting and receiving distance, and obtaining the microwave protection range of the pole; Enabling the laser and microwave transmitter to remain in a start state, and calling thelaser and microwave dual-technology detector for laser detection when a moving object is monitored to be in the microwave protection range of the pole; calling a sound and light alarm system for sound and light alarm when laser detects that the distance between the moving object and the pole or the conductor is less than the safety distance, or else transmitting alarm information to a central server.

Description

technical field [0001] The invention relates to the field of electrical engineering, and specifically discloses a method and a system for monitoring external damage of power transmission line towers linked by laser and microwave. Background technique [0002] There are many reasons for transmission line towers to be damaged by external forces. Among them, construction machinery damage is the "number one killer" that threatens line safety. Construction teams or individuals ignore the safety of power lines, operate in violation of regulations, brutal construction, illegal rock blasting, illegal tree planting, and illegal building of houses Etc., causing power line tripping, down poles, disconnection and other power outage accidents, making the transmission line facilities "scarred". [0003] At present, the prevention of external breakage of overhead transmission lines in China mainly relies on manual inspections, on-site guards, and simple physical defense. The prevention met...
