Description

technical field

[0001] The invention relates to the technical field of choke transformers, in particular to a choke transformer for solving poor branching of track circuits. Background technique

[0002] The choke transformer is a special transformer that is installed at the rail insulation of the double-rail track circuit in the electrification section, and is used to insulate the signal current in the track circuit. The signal current is separated, and the traction current can flow through it from one track circuit section to another track circuit section without being isolated by the rail insulation.

[0003] Existing choke transformers generally include an installation box on which a plurality of terminals are installed, an iron core is installed in the installation box, and a plurality of coils are installed on the iron core, and the plurality of coils are respectively electrically connected to a plurality of terminals When in use, multiple terminals are electrically c...
