In this paper

based on comparsion of the different characteristics between the traditional high voltage switchgear and intelligent high voltage switchgear

together with the state grid guidance of intelligent high-voltage switch test

as well as the national standard GB 1984—2003

the purpose of this paper is to analysis the influences of displacement transducer on mechanical performance test result of intelligent high-voltage switch. These influences include the selection of transducer type

the arrangement location and the arrangement method of transducer. Results show that

in order to promote the accuracy of parameters of mechanical test

the transducer should be arranged in a component of test CB

which could exactly reflect the motion of contacts. Moreover

to facilitate the intelligent breaker in the type test of mechanical properties

it should be considered that the selected interface protocols of transducer match with the test system.
