Abstract

The invention discloses a branch line structure of a roof wire slot and a rail vehicle. The line branch structure includes a first double-layer wire slot and a second double-layer wire slot. The first double-layer wire slot and the second double-layer wire slot A high-voltage compartment and a low-voltage compartment are arranged between the double-layer wire slots, and the first double-layer wire slot and the second double-layer wire slot both include a lower layer wire slot and an upper layer wire slot; the high-voltage wire enters the first double-layer wire slot The lower wire slot of the slot, then enters the high-voltage compartment, and then enters the upper wire slot of the second double-layer wire slot; the low-voltage line enters the lower layer wire slot of the second double-layer wire slot, and then enters the low-voltage wire slot Compartment, and then enter the upper layer wire groove of the first double layer wire groove. The branch line structure can solve the problems of high and low voltage interchange electromagnetic interference existing in the roof branch line, insufficient space for the cable off-line height and the sealing of the off-line port when the off-line port is in the wire groove.

Description

technical field [0001] The invention relates to the technical field of rail vehicles, in particular to a roof line groove branching structure of a rail vehicle. The invention also relates to a rail vehicle provided with the roof trunking branching structure. Background technique [0002] There are many types of equipment and cables inside the EMU, and the interweaving of a large number of electronic and electrical equipment and cable harnesses makes the mechanism of electromagnetic interference radiation coupling in the limited space inside the EMU very complicated. The radiation coupling of the cable harness will interfere with the signal in the vehicle and affect the normal operation of the equipment in the vehicle. Therefore, improper cable layout will cause electromagnetic interference. [0003] In order to avoid electromagnetic interference, the internal cables of the EMU are mostly arranged in wire slots or shielding sleeves. For example, for the problem of electroma...
