Description
Technical Field
The utility model belongs to the technical field of electric power system, especially, relate to a novel transmission line shaft tower earthing device.
Background
At present, a grounding system of a power transmission line tower is of great importance for lightning protection of a line, and a good tower grounding device can smoothly introduce lightning current into the ground when the line is struck by lightning. The reduction of the grounding resistance of the tower grounding device is one of the main measures for improving the lightning-resistant level of the line and reducing the lightning trip-out rate of the line. The grounding device of the tower generally adopts a radiation grounding electrode or a continuous extension grounding electrode to reduce the grounding resistance of the grounding device. In the actual operation process, because the grounding body is buried underground, the grounding body is easy to corrode and rust, the grounding device fails, the sectional area cannot meet the lightning protection requirement, and the grounding device must be timely modified. The current common reconstruction method is to dig an annular grounding groove and a radiation type grounding groove around the tower, and then connect the annular grounding body and the horizontal grounding body together in a welding manner. Because the transmission line towers are mostly positioned in mountainous areas, forest spaces and between ravines, no construction power supply exists, and the electric welding machine can only be driven to work by using the power generated by the generator. Generator and electric welding are bulky, the heavy many people of weight often need carry in handling, and this uses easy implementation in the convenient flat area of traffic, nevertheless implements the degree of difficulty very big in mountain area and forest zone, and the manpower resources is extravagant serious, and the electric welding construction very easily causes the conflagration moreover, need be equipped with all kinds of fire prevention measures, and safety precaution measure is many, and the operation scene management and control degree of difficulty is big. In addition, in mountainous areas with high soil resistivity, in order to reduce the grounding resistance of the tower grounding device below a required value, a long extension grounding electrode is often required. When the length of the grounding electrode is too large, the grounding body can present an obvious inductance effect and prevent the lightning from flowing to the far end of the grounding body. The impulse grounding resistance of the tower grounding device is the most accurate evaluation index of the current leakage capacity of the tower grounding device, and due to the existence of the inductance effect, the impact coefficient of the tower grounding device can be increased by the resistance reduction method of continuously extending the grounding body. Even if the impulse grounding resistance is reduced, the strong inductance effect of the continuous extension grounding body can also make the grounding body not fully utilized, and the economical efficiency and the practicability of the tower grounding device are reduced.
Through the above analysis, the problems and defects of the prior art are as follows:
