A kind of in-phase power supply device and power supply method for subway rigid catenary

Abstract

The invention discloses an in-phase power supply device for metro rigid catenary, which relates to the technical field of urban rail transit, and includes a base, a pantograph mounting seat, a pantograph arm, a pantograph upper frame, a main power supply transmission line and a main control unit, the top of the upper frame of the pantograph is equipped with a carbon slide plate installation mechanism, the top of the pantograph arm is equipped with an automatic arc blowing mechanism, and multiple buffer mechanism. The invention also discloses a power supply method for the in-phase power supply device of the subway rigid catenary, A: pantograph-catenary contact, B: contact arc extinguishing, C: pantograph-catenary separation, D: separate arc extinguishing. The present invention solves the cumbersome problem of the replacement process of the carbon skateboard in the existing subway rigid catenary in-phase power supply device through the setting of the carbon skateboard installation mechanism, and solves the arc of the existing subway rigid catenary in-phase power supply device through the setting of multiple buffer mechanisms The problem of easy damage to carbon skateboards and catenary.

Description

technical field [0001] The invention relates to the technical field of urban rail transit, in particular to a co-phase power supply device for a subway rigid catenary and a power supply method thereof. Background technique [0002] The existing urban subway electric traction system usually uses single-phase power supply to supply power to the locomotive set. When the pantograph is separated from the rigid catenary or is about to come into contact, the voltage between the pantograph and the catenary is too large, which will break down the air medium and generate an arc. When the arc exists for a long time, the rigid catenary or the pantograph will be damaged. After the group runs for a period of time, the operator needs to replace the carbon slide plate. The existing carbon slide plate fixing method is to use multiple sets of bolts to fix it. When installing the carbon slide plate, the installer needs to find the alignment bolts and bolt holes, which is troublesome to operate...
