Mechanism Analysis of Compensation Capacitor Abnormal Operation in Mining 6 kV Substation
Abstract：The harsh noise of part parallel compensation capacitor seriously affect the safe operation of substation during operation.In order to solve this problem,starting from the capacitor structure,utilizes the electric field forces and the relation that the work being done by electric field forces equal with stored energies of capacitors,it derived a mathematical model between electric field forces and harmonic voltage.It proved the analysis model＇s validity that the electric field force vibration frequency produced by harmonic voltage is the most sensitive area of ear perception via using the measured harmonic voltage data.So introduces some noise suppression measures.
