Abstract

In order to further improve the measurement accuracy and convenience, a novel depth of engagement intelligent measurement device for handcart circuit breaker contacts about metal-enclosed armored high voltage switchgear was developed. The device includes six sets of precision displacement measurement sensors and mainframe box. Six sets of displacement sensors were installed in the six movable contacts internal counter bore of A, B, C three-phase of high voltage switchgear handcart circuit breaker, the power lines and signal lines were lead by a peripheral ring gap plum contacts and circuit breaker handcart. With the main data processing interface box connected to the main chassis after the data processing unit, the output is displayed on mainframe box of the data display. The device structure is reasonable, easy to measure and accurate. Its measurement range is 0-50mm; its measurement accuracy is ± 0.1mm.
