A simulation excitation method and system for electrostatic damage of electric energy meter

Abstract

The present invention relates to a simulation stimulus method and system for electric energy meter electrostatic damage. The method comprises a manufacturing method of electric energy meter electrostatic damage and electrostatic damage accelerated failure method. The manufacturing method of the electric energy meter electrostatic damage comprises a step of taking a plurality of electric energy meters with the same type and selecting key devices, or directly selecting a plurality of independent electric energy meter key devices with same performance parameters to test working performance, wherein the key devices are electric energy meter devices with electrostatic damage to be made, a step of selecting electrostatic action points of the key devices and carrying out electrostatic testing by using contact type discharge after a condition that the same performance parameters of all key devices satisfy delivery requirements is confirmed, a step of applying electrostatic stress of different levels to different key devices according to a set level range of electrostatic stress for an electrostatic test, and a step of taking an electric energy meter or key device of an electrostatic test of an upper level as an electrostatic damage sample when the electrostatic stress of a level causes the failure of the key device.
