Abstract

The invention is suitable for the technical field of electric power, and provides an AC socket wiring fault detection device, which comprises a fault detection host and the fault detection host comprises a common power supply and at least three detection lines. The first detection circuit is connected in series with a first switch and a first power supply, one end of the first detection circuit is used for connecting a live wire end of a to-be-detected AC socket, and the other end is used for connecting a null line end of the to-be-detected AC socket; the second detection line is connected in series with a second switch, one end of the second detection line is used for connecting the live wire end of the to-be-detected AC socket, and the other end is used for connecting the ground wire end of the to-be-detected AC socket through the common power supply; and the third detection line is connected in series with a third switch, one end of the third detection line is used for connecting the zero line end of the to-be-detected AC socket, and the other end is used for connecting the ground wire end of the to-be-detected AC socket through the common power supply. According to the invention, the convenience of AC socket wiring fault detection can be improved.

Description

technical field [0001] The invention belongs to the technical field of electric power, and in particular relates to an AC socket wiring fault detection device. Background technique [0002] In order to better meet the convenience of passengers charging computers and mobile phones, high-speed EMUs have installed AC sockets on each seat in the car. On railway vehicles, the electrical equipment that passengers have the most contact with is the on-board AC socket, so the correctness and reliability of the wiring of the on-board AC socket are very important. [0003] At present, for the inspection of the wiring of the AC socket on the vehicle, it usually requires multiple inspectors to cooperate with the internal wiring of each AC socket junction box during the assembly stage to perform self-inspection, mutual inspection and inspection inspection, and then use the conduction test method to confirm the AC connection again. The correctness of the socket wiring, the operation proce...
