Abstract
Description
Technical Field
[0001] The invention relates to the technical field of electric power engineering equipment, and in particular to a rapid hole-forming device for a grounding down conductor of an electric power engineering project and a use method thereof. Background Art
[0002] The grounding device is the basic power facility for power engineering to achieve lightning strike and operational overvoltage protection, and is a key measure to ensure the insulation safety of power equipment and the protection of personnel from electric shock. When the live conductors of power equipment are under overvoltage conditions, the grounding grid with a lower grounding resistance can effectively protect the live equipment from tripping accidents. The grounding grid in the field of power engineering generally includes a terminal block, an underground grounding grid below the ground, and a grounding down conductor connecting the two. The common grounding down conductors in engineering are generally composed of flat steel or round steel conductor welded terminal blocks. In order to ensure that the appearance of the grounding down conductor is regular after installation, the relevant standards of the power system regulate the appearance of the grounding down conductor after installation. Regardless of whether it is a round steel or flat steel grounding down conductor, the grounding down conductor is required to be close to the pole tower.
[0003] Since some of the pole towers are located in uneven terrain conditions such as slopes, hills or mountains, the four pile foundations are not at the same height, so the height from the grounding trench to the tower leg is not consistent. During the grounding construction of power engineering, the down conductor is often bent to a suitable length first, and the terminal block is welded to the flat steel or round steel down conductor. Then the terminal block is punched and a circular hole of a suitable aperture is made on the terminal block so that it can be bolted to the tower leg. In addition, during the grounding construction of power facilities such as substations, power plants and transformers on distribution network poles, it is also necessary to perform on-site perforation of the end of the grounding down conductor. However, in the production and processing of grounding wires, especially for the processing of the terminal block at its end, there is currently a technical problem that needs to be solved urgently. Specifically, the terminal block is a key component for connecting the grounding wire to the electrical equipment, and the hole position accuracy on it directly affects the tightness and electrical performance of the connection. However, in actual operation, due to multiple influences such as material properties, processing equipment accuracy and human operation factors, the punching process of the terminal block is often difficult to achieve an ideal alignment effect, resulting in deviations in the hole position. This deviation will not only reduce the contact area between the grounding wire and the electrical equipment and increase the contact resistance, but may also cause the connection to loosen due to long-term vibration, temperature changes and other factors, resulting in the "loss of ground" of the live equipment.
[0004] Therefore, in response to the above problems, the development of a rapid hole-making device for grounding down leads in power projects has practical significance for improving the construction technology level of grounding down leads and improving the construction efficiency of power grounding projects such as power transmission, substation, and distribution. The product described in the patent has engineering application and industry promotion value. Summary of the invention
