An automatic test system and method for the on-load performance of a power distribution terminal

Abstract

An automatic test system and method for the on-load performance of a power distribution terminal can solve the technical problem that the existing on-carrier waveform burrs easily interfere with the test results. It includes an electronic load meter and a waveform monitor, and also includes test software, a database, and a multi-device switching device; wherein, the multi-device switching device communicates with the power distribution terminal through Ethernet; the test software and the database interact for data and configuration storage and reading; the test software communicates with the electronic load meter through the serial port; the test software communicates with the waveform monitor and the multi-device switching device respectively through Ethernet, and the test software controls the internal circuit of the multi-channel switching device On-off, to realize the disconnection and connection of the power distribution terminal, and then realize the automatic test of the load performance of multiple power distribution terminals. The invention can automatically judge whether the load performance of the equipment meets the requirements, and simultaneously utilizes the multi-equipment switching device to realize automatic testing of multiple equipment and improve the testing efficiency.

Description

technical field [0001] The invention relates to the technical field of power equipment inspection, in particular to an automatic test system and method for the on-load performance of a power distribution terminal. Background technique [0002] With the development of power technology, the unified integration of power primary equipment and secondary power distribution terminal equipment has become one of the hotspots in the field of distribution network research. The supporting use of primary equipment and secondary equipment requires that when the power line fails, the secondary power distribution automation terminal equipment needs to drive the primary equipment to move. Therefore, whether the loading performance of the secondary power distribution terminal equipment meets the requirements is very important to whether the primary and secondary equipment can be used together. important.
