Embodiment

[0162] The 60KW charger and discharger used for factory testing of new energy vehicle battery packs is a typical power electronic device. At present, several chargers and dischargers have just been deployed in the after-sales test station, which is still in the early stage of the product market, and is in urgent need of collecting user data and remote testing 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 switch components; test method: 60KW charge and discharge machine main When the switch is off, only the control power is turned on. The DC bridge is connected to an external 24V power supply, which can sample the DC voltage, and the inverter can sample the AC voltage. Disconnect the 24V, switch the 24V power supply to the AC current measurement terminal, a 100-ohm small resistor is co...

Abstract

A remote automatic test system for power electronic equipment, including a logic control board and an interlock switch; when the interlock switch receives a switching test instruction from the logic control board, it performs a switching operation and connects the device under test to the test environment; When receiving the switching work order from the logic control board, perform the switching operation and connect the device under test to the working environment; the logic control board receives the remote command, and sends a switching test command or switching work command to the interlock switch according to the remote command; and specifically The test content command supplies power to the device under test, collects operating data, compares the operating data with the expected data, and judges whether the device under test is normal. The invention uses a small amount of data for remote real-time monitoring and control, and can store batch data in operation at the same time to realize fast fault location; it has a remote test function and can maintain and monitor in time when medium and high-power power electronic equipment is initially put on the market.

Description

technical field [0001] The invention relates to a remote automatic testing system for power electronic equipment, which belongs to the field of power electronic equipment testing. Background technique [0002] Power electronic equipment remote automatic test system is used for medium and large power power electronic equipment, the power range covers tens of kilowatts to several megawatts, such as wind power converters, active power filters, power battery pack chargers and dischargers, shore power Remote monitoring means when inverters, energy storage converters and other products 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, which can send and receive a small amount of data remotely, but cannot remotely transmit large quantities of data. [0004] Some can process a large amount of data and transmit it to a nearby monitoring center through ...
