METHOD AND APPARATUS FOR POWER EQUIPMENT ONLINE MONITORING

摘要

The present disclosure provides a method and apparatus for power equipment online monitoring, intended to solve technical difficulties in power equipment online monitoring. The technology of the present disclosure lies in focusing laser to a to-be-detected substance inside and/or at a surface of the power equipment, generating a plasma by laser induction at the to-be-tested substance, quantitatively analyzing constituents and content of the to-be-detected substance by measuring the spectrum of the plasma, so as to determine a series of phenomena such as aging during running process of power equipment, chemical reaction state, surface absorption, deposition of electrically discharging product, vacuum leakage, trace moisture measurement, solid solution, liquid solution, gas solution and the like, thereby achieving the objective of online monitoring the power equipment.
