Description

Technical Field

[0001] The utility model relates to the technical field of electric power, in particular to a wind deviation monitoring device for a high-voltage transmission line conductor. Background Art

[0002] The electricity generated by the power plant needs to be transmitted through high-voltage transmission lines. Since the high-voltage transmission lines are installed at a high height, the wind passing through the high-voltage transmission lines will cause the high-voltage transmission lines to swing. When the amplitude of the transmission line swings too much, a wind flashover accident will occur. Once a wind flashover accident occurs, it will lead to transmission power loss and wind tripping and other faults;

[0003] Usually, in order to monitor the wind yaw swing amplitude, frequency and tilt angle of transmission lines, a swing monitoring device is installed on the transmission line for monitoring. The wind yaw swing amplitude, frequency and tilt angle of the transmission line are monitored by the swing monitoring sensor and the data is transmitted to the remote system. When installing the swing monitoring device, the cable needs to be passed through the device. Generally, a cable sheath is provided in the groove inside the device for the cable to pass through to wrap the cable surface and fix the device. Since the equipment is installed outdoors at high altitude, rainwater will penetrate into the groove on the equipment and come into contact with the sheath in rainy weather. When the sheath is in contact with rainwater for a long time, corrosion may occur, which may affect the stability of the equipment during later installation.

[0004] Therefore, we propose a device for monitoring the wind deviation of high-voltage transmission line conductors. Utility Model Content
