Design And Implement Of On-Off Test System For Circuit-breaker

On-Off test system for circuit-breaker，has long been bogged down in manual testing.Namely, the performance parameter of individual item is measured by conventionalequipments or professional testing instruments established on fundamental experimenttheories. This kind of experimental method is generally based on discrete devices in termsof its structure, and focuses on manpower operation and reads facilitated by manualcalculation according to the usage mode. Therefore, from the view of data management, itis unable to deal with large quantities of data simultaneously, and lacks in variable testingparameters stored by database which results in the incapability of comparison andsummering. Owing to human influence, it is thus admitted that the traditional testing existsproblems like reads errors magnitudes, low work efficiency, time consuming as well astesting repetitiveness, and short of reliability and safety.On the other hand, the widely-use of PC and the rapid development of modern E-techprovide great opportunities to improve the speed and accuracy of the On-Off test systemfor circuit breaker as well as dynamic tests experiment and new test methods adoption.This brings tremendous changes in automatic testing fields. While reliability, safety andstability of test are improved by using automatic testing system which combined PC’sabundant hardware and software resources with the new testing method, the cost anddifficulties are largely reduced, bring more benefits of social and economic efficiency.This paper aims to design the On-Off Test bench for circuit-breaker centered by PC.The hardware and software designed on the accordance to this program is endowed withhigh reliability and stability, and meets the requirement of the tested products in allspecification, fulfilling all index demanded by the technology.
