Drawer type multi-port synchronous automated test device for transformer protection device

Abstract

This invention provides a drawer-type multi-port synchronous automated testing device and a drawer-type multi-port synchronous automated testing system for generator-transformer unit protection devices, belonging to the field of power system automation testing technology. The device includes: an industrial control computer for running automated testing software; multiple testing modules communicatively connected to the industrial control computer, each testing module configured to provide and output at least one set of analog test signals based on control commands output by the automated testing software, the analog test signals including voltage and current signals; and wiring ports electrically connected to the signal output terminals of each testing module, configured to connect the analog test signals output by the multiple testing modules to multiple sampling ports of the device under test. This invention can improve the testing efficiency of automated relay protection testing.
