A New Piezoelectric Ceramic Electronic Voltage Transducer and its Principle Design

Abstract

In this paper, the piezoelectric ceramic electronic voltage transducer principles is researched, a new internal structure of the measurement system is put forward and the signal processing methods are discussed. On the basis of the analysis of freedom cantilever optical measurement methods for the longitudinal piezoelectric deformation, we proposes the piezoelectric resonance method to detect amplitude of piezoelectric ceramic and cleverly designed mechanical structure, in which the lightweight elastic material is used to support the resonance thin film. This structure overcomes the impact of cantilever longitudinal self-gravity and horizontal friction between cantilever and piezoelectric ceramic, and can improve the deformation measurement accuracy. 10kV 0.05 class transducer voltage measurement accuracy is achieved theoretically.
