Description

Technical Field

[0001] This utility model relates to the field of electrified railway technology, specifically to a PW line shoulder frame outside a railway tunnel. Background Technology

[0002] PW line shoulder brackets are specialized supports used to secure protective conductors (PW lines). They are typically installed on overhead contact line supports and connected to the PW lines via insulators. Their function is to ensure the safe installation of PW lines in AT power supply sections, primarily providing a metallic path during faults and ensuring the stable operation of the traction power supply system.

[0003] PW line shoulder supports are typically made of angle steel and are installed on the field side of the contact wire support (the side furthest from the line), parallel to the positive feeder (AF line) shoulder supports. In special locations such as tunnel entrances, PW line shoulder supports are often installed on the top of H-shaped steel columns facing the line to ensure a safe distance from the positive feeder.

[0004] PW line shoulder brackets are support structures used in overhead contact systems to install PW lines (protective wires). Their main functions include: (1) Structural features: PW line shoulder frame is usually welded, for example, the shoulder frame steel is welded together, and a hanging component is added at an appropriate position. The component is connected to one end of the insulator.

[0005] The PW line shoulder frame and H-beam steel column are connected by bolt pairs. For example, the bottom plate of the shoulder frame connection end is reserved with connection holes, and the flange plate of the H-beam steel column is reserved with connection holes. Matching hole positions and fastener connection are used.

[0006] (2) Functions: First, protection: By maintaining a safe distance between the insulator and the tunnel arch wall, the PW line is prevented from rubbing against or short-circuiting with buildings or equipment. Second, grounding protection: As a return path for traction current, it ensures the safe operation of the system. Third, standardized construction: It needs to be recycled simultaneously with all spare parts to ensure the accuracy of equipment records and safe management.

[0007] (3) Installation Specifications: Insulating supports and supporting insulators must be used at special locations such as tunnel entrances to ensure a distance of at least 500mm from buildings, preventing encroachment or falling risks. Under the current hot-dip galvanizing process, the corrosion resistance of fastener threads cannot reach a 20-year service life. Therefore, fasteners need to be completely replaced after a certain number of years of use. Replacement requires live-line work, must be carried out in sections, has a long cycle, high cost, and high risk.

[0008] Therefore, this utility model provides a PW line shoulder frame that can be applied to steel supports of various shapes. Utility Model Content
