The invention discloses a traction cable connection device and a track traffic load traction cable harmonic wave treatment device. The traction cable connection device comprises a support structure, awire connection structure, and a cable conversion structure. The support structure comprises an installation plate, a storage cover and an end cover. The storage cover is arranged on the installationplate. The wire connection structure is electrically connected with a harmonic wave adjustment device. The cable conversion structure comprises a cable connection assembly, a sliding rod, a moving blade, a first screw, a second screw, a fixed blade and a guidance sleeve. The guidance sleeve is fixed between the end cover and the installation plate. The cable connection assembly is embedded in thebottom of the guidance sleeve and electrically connected with the wire connection structure. The first screw penetrates through the end cover and the top of the guidance sleeve and is used for push atraction cable to be connected with the cable connection assembly. The second screw penetrates through the end cover and the top of the guidance sleeve and connected with the moving blade. The fixedblade is fixed at the bottom of the guidance sleeve. According to the invention, a harmonic wave treatment device is rapidly added in a current track power transformation system, so harmonic waves arereduced.
Description
technical field [0001] The invention relates to the technical field of rail alternating current management, in particular to a traction cable connection device and a rail transit load traction cable harmonic control device. Background technique [0002] Harmonic current is the general term for the sinusoidal components whose frequency is an integer multiple of the original periodic current frequency when the non-sinusoidal periodic current function is expanded according to the Fourier series, and the harmonic current whose frequency is k times the original periodic current frequency is called k Sub-harmonic current, the harmonic currents with k greater than 1 are also collectively referred to as high-order harmonic currents. The generation of harmonic currents in track traction cables will lead to overheating of cables, overheating of transformers, and damage to reactive power compensation devices. Harmonic The use of fast processing equipment improves the work efficiency an...
