Abstract

The invention provides an IEC (international electrotechnical commission) 61850 based verification system and an IEC 61850 based verification method for a switch mechanical characteristic testing device. The system is communicated with a to-be-tested device through an IEC 61850 network, and outputs state quantity and analog quantity to test the switch mechanical characteristic testing device. The verification method includes electric current accuracy testing, mechanism case temperature testing, energy storage medium pressure testing, opening and closing time testing, time synchronization function testing, diagnostic analysis function testing and repeatability testing. The verification system and the verification method have the advantages that various states of switchgears are replaced by analog signals and switching signals, so that repeatability is high, testing process is concise, and various working conditions, fault conditions and the like of the switchgears can recur; the verification system and the verification method are suitable for testing, functional identification and verification of the switch mechanical characteristic testing device in the electric power industry.

Description

technical field [0001] The present invention relates to a system and method in the technical field of monitoring the state of switch mechanical characteristics of high-voltage substation equipment, in particular to a calibration system and method for a switch mechanical characteristic testing device based on IEC61850. Background technique [0002] High-voltage switchgear is an important control and protection device in the power system. The task of the circuit breaker in the high-voltage switchgear is to put the power equipment or line into or out of operation according to the needs of the grid operation, or to remove the failed power equipment or line from the grid. Quick removal to ensure the normal operation of the fault-free part of the grid. Therefore, once the high-voltage switchgear itself fails, it may cause larger chapters in the power system, and in severe cases, it will cause huge losses. [0003] Among the various types of fault defects of high-voltage switchgea...
