Power transmission line intelligent temperature measuring strain clamp

Abstract

The invention provides a power transmission line intelligent temperature measuring strain clamp comprising a wedge clamp head, a wedge clamp base, a lining pipe, a connecting ring, a wireless temperature measuring unit, a connecting sleeve and a solar power supply unit which are arranged from inside to outside. The wireless temperature measuring unit comprises a PT100 temperature sensor, a signalconditioning module, a microprocessor and a zigbee communication module which are connected in turn. The wireless temperature measuring unit is arranged on the internal wall of the lining pipe, and other modules are arranged between the wedge clamp base and the strain clamp connecting sleeve. A zigbee module antenna is arranged on the external surface of the strain clamp connecting sleeve. The solar power supply unit comprises two parts of a flexible solar cell panel and arc polymer cells. The solar cell panel wraps the external surface of the strain clamp connecting sleeve for charging the arc polymer cells. The arc polymer cells supply power to the wireless temperature measuring unit. According to the intelligent power grid strain clamp, the problems of low accuracy of the original leadtemperature measuring unit and inconvenient installation can be solved.

Description

technical field [0001] The invention relates to the field of intelligent measurement and control of transmission lines in smart grids, in particular to an intelligent temperature measurement and strain clamp for transmission lines. Background technique [0002] In recent years, with the continuous development of my country's industrialization, people's electricity consumption has increased year by year, resulting in an increase in the grid load, and many provinces and cities have experienced electricity shortages, seriously affecting industrial development and people's living needs. At present, power grid companies mainly use two means to increase power transmission capacity. On the one hand, they erect new lines to increase the voltage level and transmission capacity; [0003] The dynamic capacity increase technology is a method to dynamically adjust the transmission capacity of the wire according to the real-time load of the wire and the real-time temperature of the wire. ...

AI Technical Summary

Problems solved by technology

However, due to the special environment and structure of the transmission line, the existing sensors have some problems, such as stress concentration at the installation position of the sensor, which leads to wear of the strands, low measurement accuracy and unstable signals caused by environmental factors, etc. These problems are often Difficulties in the application of dynamic capacity expansion technology
