A power connection device with pull force detection function

Abstract

The invention relates to an electric power connection device with a tension detection function, which comprises a housing with a built-in tension detector. The side wall of the housing is provided with an inlet / outlet opening communicating with the inner cavity of the housing. One end of the housing is integrally formed with a connecting portion connected to the pole tower, and the other end of the housing is integrally formed with another connecting portion that can be connected with the insulator string, so it not only has a connection function, but also has a tension detection function; Since the tension detection device can be built into the inner cavity of the housing, the tension detection device has strong stability and anti-interference ability; since the power connection device of the present invention has both the connection function and the tension detection function, the existing technology is saved. Adding tension sensors and transitional connecting parts between the required insulator strings and connecting devices not only has a simple process, greatly reduces material and labor costs, but also improves the safety of the transmission line.

Problems solved by technology

[0002] At present, high-voltage transmission lines are generally erected through metal poles and towers. The towers and transmission lines are generally connected by insulator strings and clamps, and special connection devices are required for auxiliary installation between insulator strings and pole towers. The existing connection devices only With the function of connection, it is unable to detect the force of the transmission wire on the tower and the force of the wire itself when the line is covered with ice or wind load

[0003] In order to detect the force of the transmission wire on the tower and the force of the wire itself when the line is covered with ice and wind load, at present, the tension sensor is generally used for detection, but due to the uniqueness of the connection device between the insulator string and the tower of the power transmission line, it is now Some tension sensors cannot be directly connected to the insulator strings, but need to add other transitional connection parts to assist in the installation. Even if the tension sensors are installed, the stability and long-term performance of their work in harsh outdoor environments cannot be guaranteed. After adding tension sensors and transitional connecting parts between the insulator string and the connecting device, not only the process is complicated, the cost is greatly increased, but also the connection length between the tower and the transmission line is increased, which is beneficial to the lightning protection of the conductor and the safe distance from the tower. impact, thereby affecting the safety of transmission lines
