Abstract

The invention relates to an automatic detection system and method for the sag of a power transmission line. The automatic detection system comprises a Beidou satellite, a self-propelled trolley and aremote host. The self-propelled trolley is arranged on the power transmission line and comprises a mounting bracket, a battery unit at the bottom of the mounting bracket, a driving unit in the middleof the mounting bracket, a communication unit at the top of the mounting bracket and a sag measuring probe at the front end of the mounting bracket, wherein the communication unit communicates with the Beidou satellite through satellite signals, communicates with the remote host through wireless signals, and is connected with the driving unit and the sag measuring probe. The automatic detection system and method have the advantages that full-automatic measurement of the sag is realized, and the precision of measurement results is high; data is automatically recorded and stored, manual recording is not needed, and the work is not influenced by human factors.

Description

technical field [0001] The invention relates to the field of measurement in the electric power industry, in particular to an automatic detection system and method for sag of a power transmission line. Background technique [0002] Accurate observation of the sag value of overhead transmission lines is an important link in the quality assurance of overhead construction of transmission lines. The harm caused by the size of the sag to the transmission line is: the sag value is too small, the stress of the tensioned wire is large, and if the temperature drops, the wire will be forced to be further elongated or even broken. Especially under the weather conditions of rain and snow disasters in the south, the tower is prone to the risk of lodging. If the sag value is too large, the safety distance to the object to be crossed is not enough. Under the influence of multiple factors such as continuous overvoltage of the system, high temperature and heavy load, the wire will swing by i...
