Abstract

The invention provides a real-time voltage monitoring circuit for a discharge coil of a high-voltage parallel capacitor bank. The circuit comprises an energy taking circuit and a measuring circuit which are integrally designed, the energy taking circuit is powered by a high-voltage discharge coil, an additional energy supply device is not needed, and the measuring circuit realizes voltage measurement by a voltage transformer. The real-time voltage monitoring circuit for the discharge coil of the high-voltage parallel capacitor bank is provided on the basis that the structure of power grid equipment is not changed, and online accurate monitoring of the real-time running state of a parallel capacitor is achieved.

Description

technical field [0001] The invention relates to the field of electric power, in particular to a real-time voltage monitoring circuit for a discharge coil of a high-voltage parallel capacitor bank. Background technique [0002] High-voltage shunt capacitor banks are widely used in substations as reactive power compensation equipment to improve the power factor of loads, improve voltage quality, reduce network losses, and increase system voltage stability. The discharge coil is used in the power system to connect with the high-voltage shunt capacitor, so that the residual charge after the capacitor bank is removed from the power system can be quickly discharged. The installation of discharge coils is a necessary technical safety measure for parallel capacitors in substations. It can effectively prevent overvoltage and overcurrent that endanger the safety of equipment when the capacitor bank is closed again, and ensure the safety of maintenance personnel. Safety. Therefore, i...
