Abstract

The invention discloses a safe interlocking control method for an electric locomotive garage-in motor car. A garage-in motor car key A, a current transformer cabinet key, auxiliary cabinet keys B and a mechanical interlocking device are arranged. Only when the key A is rotated to the locking position, will the keys B be rotated to the unlocking position from the locking position and pulled out. Only when the two keys B are located at the position of the mechanical interlocking device and restored to the locking position from the unlocking position, will the key A be restored to the unlocking position from the locking position and be pulled out. Only when a cabinet door is closed, will the keys B be rotated to the unlocking position from the locking position and be pulled out. Only when the key A is in a closing, namely an unlocking state, will a garage-in motor car contactor be closed to provide electricity to a driving device. The electric and machine interlocking functions are achieved at the same time, the safety of the garage-in motor car is improved, and operators can be effectively prevented from getting an electric shock.

Description

technical field [0001] The invention relates to a safety interlocking control method for trains in an electric locomotive garage, belonging to the technical field of railway locomotives. Background technique [0002] When the electric locomotive is in the commissioning depot, test depot and maintenance depot, it cannot obtain electric energy from the catenary to directly drive the locomotive. It needs to use the power supply in the depot to drive the electric locomotive to realize the movement of the locomotive in the depot or out of the depot. The power supply of the train in the depot mainly has the following specifications: 3-phase AC380V, DC600V, AC220V, etc., all of which exceed the specified human body safety voltage requirement of 36V. During the operation of the EMU in the depot, if the door of the screen cabinet where the live device is located is not locked (such as auxiliary cabinet, converter cabinet), the operator can easily come into contact with the live devic...
