The system comprises a loosely coupled transformer with separable primary side and secondary side, an auxiliary carrying mechanical arm, a gripper, a rectifier device and a power network source. According to the method, a primary side coil and a primary iron core, connected with a charging station, of the loosely coupled transformer are accurately connected to a secondary side coil and iron core of the tail part of the electric locomotive by the carrying mechanical arm; and AC of the power network source is rectified into DC through the rectifier device for charging the storage battery of the electric locomotive. According to the inductively coupled power transmission-based mining electric locomotive charging system and method, the safety is high, the reliability is high, the service lifetime is long, the charging efficiency is high, the operation is simple, the charging process is simplified and the inductively coupled power transmission-based mining electric locomotive charging system and method are suitable for a poor working environment under the coal mine.
Description
technical field [0001] The invention relates to a mining electric locomotive charging device and method based on loosely coupled electric energy transmission, relates to a mining electric locomotive, and belongs to the field of mining electric locomotive charging. technical background [0002] Mining electric locomotive battery is a typical underground equipment that needs wired charging. As a secondary energy storage device, it plays an important role in the auxiliary transportation process of coal mines. It has a wide range of applications and good storage voltage effects. It is a mining battery. The power source of the electric locomotive provides direct DC power for the drive motor. [0003] One of the traditional electric locomotive charging methods is to set up a charging station on the well, drive the electric locomotive to the well when it needs to be charged, and unload the battery for charging. This method takes a long time to prepare, the operation is cumbersome, ...
