Embodiment

[0162] The 60KW charging and discharging motor used for factory testing of new energy vehicle battery packs is a typical power electronic device. At present, several charging and discharging machines have just been deployed in the after-sales test station, which is still in the early stage of the product market. It is urgent to collect user data and remote test technical support. Remote test content: including testing the on, off and short circuit status of the main circuit, the quality of the power bridge IGBT, the sampling of the main circuit, AC voltage, AC current, DC voltage, etc., and related switching components; test method: 60KW charging and discharging motor main The switch is turned off, only the control power is turned on, and the DC bridge is connected with an external 24V power supply, which can sample DC voltage, inverter, and sample AC voltage. Disconnect the 24V, switch the 24V power supply to the AC current measurement terminal, and connect a 100 ohm small re...

Abstract

The invention discloses a power electronic equipment remote automatic test system. The system comprises a logic control board and an interlocking change-over switch. When the interlocking change-overswitch receives a switching test instruction of the logic control board, switching operation is executed, and the tested equipment is connected to a test environment, when a switching work instructionof the logic control board is received, switching operation is executed, and the tested equipment is connected into a work environment, the logic control board receives the remote instruction and sends a switching test instruction or a switching work instruction to the interlocking change-over switch according to the remote instruction, and the specific test content instruction supplies power tothe tested equipment, collects operation data, compares the operation data with expected data, and judges whether the tested equipment is normal or not. According to the invention, a small amount of data is used for remote real-time monitoring and control, batch data in operation can be stored, and rapid fault positioning is realized,and the system has a remote test function, and can be used for timely maintaining and monitoring medium-high power power electronic equipment initially put into the market.

Description

technical field [0001] The invention relates to a remote automatic test system for power electronic equipment, which belongs to the field of power electronic equipment test. Background technique [0002] The remote automatic test system for power electronic equipment is used for power electronic equipment with medium and large power, the power range covers tens of kilowatts to several megawatts, such as wind power converters, active power filters, power battery pack charging and discharging machines, shore power Remote monitoring means when products such as frequency converters and energy storage converters are initially put on the market. [0003] Most of the current power electronic equipment does not have remote testing and remote monitoring functions. A small amount of GPRS is used to send and receive a small amount of data remotely, but cannot transmit large amounts of data remotely. [0004] Those that can handle a large amount of data are transmitted to the nearby mo...
