Abstract

The invention discloses a power supply method of CRH380BL type multiple units under an un-wheeling repair mode. The method comprises the five steps of AC380V power supply external connection, multipleunit semi-physical simulation power supply device access, full-column medium voltage power supply loop establishment, full-column low-voltage power supply loop establishment and power equipment condition monitoring, achieves continuous power supply of the CRH380BL type multiple units under the un-wheeling repair mode, and can monitor and display a storage battery voltage in real time so that themultiple units can still carry out live operation in a decompiled state, and the non-electric and electric operations of the two unit multiple units can be alternately interspersed at the same time, which can improve the un-wheeling repair operation efficiency of the multiple units and shorten the inspection cycle.

Description

technical field [0001] The technical proposal belongs to the related field of motor train technology, and particularly relates to the field of high-level maintenance of motor train units. Background technique [0002] In view of the characteristics of high efficiency and short cycle of the mainstream repair mode of CRH3 short-braided EMUs, the maintenance unit usually separates 8 / 9 cars of CRH380BL16-section long-braided EMUs, and uses the existing locomotive resources to carry out repairs. 8-section overall frame car repair. However, since the 16-car formation is divided into two independent units, and the original WTB train bus that runs through the entire train is disconnected, when the CCU software of the original 16-car formation train is used, the feedback signal of the second half of the train cannot be obtained, and the formation of A true communication loop and the lack of associated head and tail relays make it impossible to establish an effective security loop. ...
