Problems solved by technology

In view of the above technical problems, application number 201310261898.3 discloses a high-voltage transmission wire sag measurement device and a method for measuring sag, which uses a microwave radar ranging sensor, although it can measure transmission line sag, but compared with this design method The cost of the ultrasonic range finder is much higher, which is not conducive to the large-scale use of the product; in addition, when it is measured on site, due to factors such as complex terrain, it may not be able to effectively receive radar echoes, resulting in false alarms

Abstract

The invention relates to a power transmission line sag measurement method based on ultrasonic distance measuring and a system thereof. The system comprises an ultrasonic range finder fixed on a power transmission line. An ultrasonic emission head in the ultrasonic range finder points to a downward direction. A ground where the pointing of the emission head is arranged to be a level base surface. The ultrasonic range finder emits an ultrasonic wave to the level base surface and collects and receives the ultrasonic wave reflected by the level base surface. A collected signal is calculated and processed and correlation information is fed back to a monitoring terminal. The monitoring terminal receives the information and then carries out further processing, and outputs alarm information. The ultrasonic range finder is fixed to the power transmission line. An ultrasonic transmitting terminal in the ultrasonic range finder vertically points to a downward direction. An underface ground is provided with the level base surface so as to ensure that an ultrasonic echo can be received. Detection reliability is increased. Through using an ultrasonic distance measuring method to measure a power transmission conductor sag, the price of the ultrasonic range finder is low so that large-scale use can be achieved.

Description

technical field [0001] The invention relates to the technical field of electric power transmission, in particular to a transmission line sag measurement method and system based on ultrasonic distance measurement. Background technique [0002] The sag of the high-voltage transmission line is an important indicator of the safe operation of the line. The size of the sag of the transmission line should be controlled within a certain range. The pole tower structure or the cycloid caused by the wind will cause a phase-to-phase short circuit, which will generate arcs and sparks to ignite the surrounding combustibles. Therefore, the sag detection of the high-voltage transmission line is particularly important for the safe transmission of the entire electric energy. In view of the above technical problems, the application number 201310261898.3 has announced a high-voltage transmission wire sag measurement device and a method for measuring sag, which uses a microwave radar ranging sen...
