Automatic test system and method of on-load performance of power distribution terminal

Abstract

The automatic test system and method of the on-load performance of a power distribution terminal can be used to solve a technical problem that an existing on-load waveform burr is easy to generate interference on a test result. The system comprises an electronic load meter, a waveform monitor, test software, a database and a multi-equipment switching device. The multi-equipment switching device iscommunicated with the power distribution terminal through an Ethernet. The test software and the database are interacted to store and read data and configuration. The test software and the electronicload meter are communicated through a serial port. The test software, the waveform monitor and the multi-equipment switching device are communicated through the Ethernet. The test software realizes the disconnection and the access of the power distribution terminal through controlling the on and off of the internal circuit of a multi-path switching device so as to realize the automatic testing ofthe on-load performance of the multiple power distribution terminals. In the invention, whether the on-load performance of the equipment accords with a requirement can be automatically determined, and the multi-equipment switching device is used at the same time so as to realize the automatic testing of the multiple equipment and testing efficiency is increased.

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.
