Abstract

The invention provides a single-stranded flat copper strip vertically-wound hollow coil suitable for a track circuit. The hollow coil is of a structure that an upper layer and a lower layer are symmetrically arranged, wherein the hollow coil is prepared from a single-stranded flat copper strip wire through vertical winding, each turn of coil body in the hollow coil is in a rounded rectangle shape,and supporting between the turns is achieved by using uniform-thickness epoxy resin gaskets. Three leading-out terminals are directly led out of the hollow coil, and the upper end of the hollow coilis fixed with a multi-supporting-point press plate structure. According to the single-stranded flat copper strip vertically-wound hollow coil, it is ensured that electric parameters of the upper and lower layers of the hollow coil are balanced, the individual difference is small, and insulation between the turns is achieved.

Description

technical field [0001] The invention belongs to the technical field of track circuits of railway systems, and in particular relates to a vertically wound air-core coil of a single-strand flat copper strip suitable for track circuits. Background technique [0002] The track circuit is the basic safety equipment of the signal, and it is a circuit system composed of steel rails as conductors. After the train wheelset contacts with the rail to form an electrical connection, it will change the electrical topology of the track circuit, so as to achieve the functions of checking section occupancy, checking the integrity of the rail, and transmitting information to on-board equipment; traction power supply is the energy supply system of electrified railways, 50Hz high voltage The alternating current is fed to the electric locomotive through the substation, the catenary, and the pantograph. After the transformation, it is used as the power of the train traction, and finally transmitt...
