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...

Problems solved by technology

[0004] However, in reality, due to the self-oxidation of the double rails and the adhesion of external substances, it is easy to cause poor track circuit shunting, which affects the detection of track circuit signals and separated track circuit signals, and is likely to cause safety accidents, and most of the existing choke transformers Bolts are used to fix and install at the designated position. When the train passes at high speed, it is easy to cause frequent vibrations, which will easily affect the service life of the choke transformer and increase the cost of railway operation and maintenance.
