POWER SUPPLY OF SELF-CONTROL SOURCES FOR TRANSFORMER

摘要

autonomous power supply in the pole transformer of the present invention for achieving the above object, the transformer having a housing and, provided on the housing of the transformer, and an amount proportional to the vibration generated in the variable pressure process of the transformer, and a piezoelectric element for generating a negative self-powered by the electric charge, is coupled to the piezoelectric element can be the autonomous power amplifier comprising: a resonant member to induce resonance to the resonance element, the one end is fixed to the housing of the transformer and the other end is installed to be inclined and form a free end and a metal member on which the piezoelectric element is installed, the freedom of the metal member is installed on the end side comprises a resilient member connecting the weight to the vibration based on the vibration of the transformer, the weight and the metal member.
