Power transmission line strain insulator string state monitoring system and monitoring device thereof

Abstract

The invention discloses a power transmission line strain insulator string state monitoring system and a monitoring device thereof. The system comprises a strain insulator string, a state monitoring device, a wireless receiving gateway, a background server and a display terminal. The two sides of the strain insulator string are respectively provided with an intelligent force measurement connectionfitting. The two intelligent force measurement connection fittings are respectively connected with the iron tower and the intelligent force measurement strain clamp. An inclination angle sensor is arranged on each intelligent force measurement connection fitting; the detection state parameters are sent to the wireless receiving gateway, the wireless receiving gateway transmits the data to the background server, and the background server performs comprehensive calculation on the tension, temperature and inclination angle data, analyzes the operation state of the strain insulator string, transmits the operation state to the display terminal and displays abnormal alarm information in real time. According to the monitoring system and the monitoring device thereof, the tension, inclination andtemperature monitoring devices are arranged at the key positions of the strain clamp insulator string, so that all-weather multi-parameter state monitoring of the running state of the strain clamp insulator string can be realized.

Description

technical field [0001] The invention relates to the monitoring of the running state of tension insulator strings in power transmission lines, in particular to the monitoring of the stressed state of the tension insulator strings of high-voltage transmission overhead lines and the heating of overcurrent positions, and belongs to the field of on-line monitoring of power equipment. Background technique [0002] Overhead transmission lines are an important part of my country's power grid system, and their operating status is directly related to the production and life of the people. The strain insulator string is a combination of insulators and fittings. It is located between the transmission line tower and the wire, and plays the role of pulling the wire and electrical insulation between the high-voltage position and the tower. According to the statistics of the transport inspection department, accidents such as insulators falling off, strain clamps breaking, and strain clamps ...

AI Technical Summary

Problems solved by technology

According to the statistics of the transportation inspection department, accidents such as insulators falling off strings, strain clamps breaking, and strain clamps crimping conductors off-line and other accidents occur from time to time.

The reasons are, first, that the product itself may have quality defects or irregular installation; Affected by wire tension, wind load, ice weight, breeze vibration and other factors, the service life is greatly shortened

Due to the lack of regularity of the above-mentioned many influencing factors, it is difficult to form a quantitative standard to determine the time for maintenance or replacement parts, which has always been a difficult problem for the inspection department

The traditional method of judging the status of insulator strings mainly uses manual observation or drone inspection, which is affected by the weather and has poor timeliness. It is impossible to find problems in time and eliminate potential safety hazards.
