Description

Technical Field

[0001] The invention belongs to the technical field of power transmission equipment, and in particular relates to an automatic adjustment device for releasing the tension of a ground wire of a power transmission line. Background Art

[0002] Transmission towers are used to support transmission lines in overhead transmission lines. They are mostly made of steel or reinforced concrete and are the main supporting structure of overhead transmission lines. The main function of the tower is to support the conductors and ground wires, and to keep a certain distance between them and the ground to ensure the safe and stable operation of the transmission line. Transmission towers can be divided into wooden poles, cement poles and metal poles according to their materials. Among them, cement poles are widely used in short-distance power transmission due to their advantages such as long service life and small maintenance workload, while long-distance high-voltage overhead lines use tower-type metal poles; transmission towers can be divided into self-supporting towers and guyed towers according to their structural form. Self-supporting towers are stable by their own foundations, while guyed towers are installed with symmetrical guy wires on the tower head or tower body for stable support. The latter can save steel, but the distribution of guy wires takes up more space and its scope of use is limited; transmission towers can be divided into load-bearing towers, straight towers, transposition towers and large-span towers according to their functions. Among them, load-bearing towers are convenient for segmented construction and limit the scope of accidents. Straight towers are the most commonly used structures on the line, which bear the suspension of conductors and ground wires and meteorological loads. In long-distance transmission lines, overhead ground wires, also known as lightning arresters, are wires directly connected to the earth on high-voltage and extra-high-voltage lines. Their main function is to prevent lightning, reduce the chance of lightning directly striking the wires, and improve the safety of line operation. When lightning strikes a tower, a portion of the lightning current can be diverted through the overhead ground wire, reducing the potential at the top of the tower, improving the lightning resistance level, and at the same time reducing the lightning induced overvoltage on the transmission line caused by the discharge of thunderclouds near the line to the ground. The sag of the overhead ground wire refers to the distance in the vertical direction from any point on the overhead wire or ground wire to the connecting line of the suspension point. The tension and sag of the overhead ground wire directly affect the safety and stability of the transmission line. Reasonable sag can ensure that the conductor maintains a safe distance from the ground, buildings, etc., and prevent discharge or short-circuit accidents caused by excessive sag. Adjusting the tension can change the stress state of the conductor, so that it can maintain a stable operating state under various meteorological conditions. By adjusting the sag and tension, the electrical performance of the transmission line can be optimized, the energy loss can be reduced, and the transmission efficiency can be improved. Due to the complexity of the outdoor environment, during the long-term operation of the transmission line, the sag and tension of the ground wire will change due to the settlement of the tower, the tilt and displacement of the insulator or other components, which threatens its safety in use. Therefore, it is very necessary to provide an automatic adjustment device for the tension release of the ground wire of the transmission line. Summary of the invention

[0003] The purpose of the present invention is to overcome the shortcomings of the prior art and to provide an automatic adjustment device for releasing the tension of the ground wire of a power transmission line, which can effectively assist the staff in adjusting and controlling the tension and sag of the ground wire of the power transmission line, so as to avoid changes in the sag and tension of the ground wire due to tower settlement, insulator tilting and displacement during the long-term operation of the power transmission line, thereby ensuring its safe use.
