Description

Technical Field

[0001] This utility model relates to the field of high-speed railway traction substations, specifically a quick-installation structure for the construction of lightning rods in high-speed railway traction substations. Background Technology

[0002] High-speed railways typically utilize traction substations. A traction substation is a facility that converts electrical energy from power plants via transmission lines into voltage suitable for locomotives and rolling stock, distributing it to the overhead contact line or contact rail (third rail). These substations are classified as DC traction substations or AC traction substations. In the high-speed railway traction power supply system, the traction substation plays the role of the "heart," providing direct power to trains. To protect the traction substation and outdoor electrical equipment from direct lightning strikes, independent lightning rods are usually installed at designated locations to guide the lightning current to the rods and then to the ground. However, traditional lightning rod installation structures typically rely on multiple bolts and flanges for installation and fixation, resulting in complex and time-consuming installations that reduce the efficiency of personnel. Utility Model Content
