Contact network power receiving detector and power supply debugging method

Abstract

The invention discloses a contact network power receiving detector and a power supply debugging method, and belongs to the technical field of contact network detection, the contact network power receiving detector comprises a control mainboard, and the control mainboard is connected with an input interface, an output interface, a power conversion module, a signal acquisition module, a voltage and current preset module and a circuit on-off module. When the contact network power receiving detector carries out power receiving detection, a conventional power supply terminal voltage is connected through the power supply conversion module and is converted into a high voltage to be output, so that the power receiving requirement of the contact network is matched, and the power receiving condition of the contact network is judged according to the voltage and current data of the output port; the independent judgment of the power receiving condition of the overhead line system is realized; and meanwhile, the detection condition of the contact network power receiving detector is monitored in real time by arranging a voltage and current presetting module, a circuit on-off module and the like, and voltage and current output is cut off in time when an output fault occurs, so that damage to equipment or operators caused by the output fault is avoided.

Description

technical field [0001] The invention belongs to the technical field of catenary detection, and in particular relates to a catenary power receiving detector and a power supply debugging method. Background technique [0002] The catenary is the high-voltage power transmission line used by the pantograph in electrified railways. The commissioning of the domestic rail transit power supply system is to use temporary power access, phase-by-phase detection, on-site measurement and human judgment to complete the functional verification of the power supply system. [0003] The traditional test, commissioning and detection method has high requirements on the professional ability and operation level of technicians, and the access of temporary electricity will pose a great threat to the safe and civilized construction on site, and during the single commissioning, joint commissioning and joint commissioning , it takes 7-8 people to cooperate with wiring, exchange the debugging port, and...
