Abstract

The invention discloses a traction motor junction box (1), which comprises a junction box main body (11). The junction box main body (11) is fixed on a motor base (2); the junction box main body (11)is internally provided with a three-phase cable line (13) and a wiring seat (12) arranged oppositely to a deflection wheel; the wiring seat (12) is used for fixing the three-phase cable line (13); andthe wiring seat (12) is far away from the vertical symmetrical surface of the motor and arranged oppositely to the deflection wheel. The self arc of the motor side wall is effectively used to compensate the height difference between the actual height of the wiring seat and the allowed height, and a large creepage distance and a large electrical gap are achieved. According to the above traction motor junction box (1), in a condition of not changing the motor main body structure, the problem of limited space below a bogie can be effectively solved, and outgoing of the three-phase cable line (13) is also facilitated.

Description

technical field [0001] The invention relates to the field of rail transportation, in particular to a motor. The invention also relates to a traction motor junction box. Background technique [0002] The motor is one of the important parts of the electric locomotive, which is installed on the bogie under the car body. When the electric locomotive is in the traction state, the motor converts electrical energy into mechanical energy, which makes the wheel set rotate and then drives the locomotive to run. [0003] Please refer to figure 1 , figure 1 It is a schematic diagram of a connection structure between a typical traction motor junction box 1 and a motor frame 2 in the prior art. The traction motor junction box 1 is generally installed directly above the traction motor frame 2 and below the bogie (not shown in the figure). The traction motor terminal box 1 includes a terminal box main body 11 and a terminal base 12 disposed inside the terminal box main body 11 , and th...
