Description

Technical Field

[0001] The utility model relates to the technical field of lightning arresters, in particular to a compact lightning arrester suitable for high-voltage transmission lines. Background Art

[0002] A lightning arrester is an electrical device that can release lightning or release power system operating overvoltage energy, protect electrical equipment from transient overvoltage (lightning overvoltage, operating overvoltage, power frequency transient overvoltage shock), and cut off the continuous current to prevent the system from grounding short circuit. When the lightning shock wave transmitted to the substation along the line exceeds the protection level of the lightning arrester, the lightning arrester will first discharge and safely introduce the lightning current into the earth through a good conductor. The grounding device is used to limit the lightning voltage amplitude to below the lightning shock level of the protected equipment, so that the electrical equipment is protected. In high-voltage transmission lines, compact lightning arresters are required for lightning protection; the existing patent application number is CN201921992298.3, a multifunctional high-voltage line lightning arrester, "including support The bracket seat is provided with a high-voltage stainless steel connector on its upper end face. The upper end face of the high-voltage stainless steel connector is fixedly connected to the support insulator, lightning arrester insulator, galvanized hardware, and the first unit lifting lug in sequence from bottom to top. An insulating body is provided on the left side of the high-voltage stainless steel connector. Multiple evenly distributed lightning arrester units are fixedly connected to the outer wall of the lightning arrester insulator. Resistor plates are provided below each of the multiple lightning arrester units. An upper discharge device and a lower discharge device are fixedly connected to the front end face of the support insulator in sequence from bottom to top. A support insulator is cleverly used between the upper and lower discharge devices. When the upper and lower discharge devices discharge, the support insulator and the insulator achieve excellent insulation effect, are less likely to cause leakage, and provide excellent protection. The insulating body in this application is fixed to the bracket seat, and its position cannot be adjusted as needed, resulting in poor flexibility. Furthermore, the high-voltage stainless steel connector is fixed to the bracket seat by fixing bolts. The upper discharge device is close to the bracket seat, making it difficult to tighten the fixing bolts, which can easily cause loosening. Therefore, we propose a compact lightning arrester suitable for high-voltage transmission lines. Utility Model Content
