摘要
为了解决现有高压开关柜采用电压差法核相时,由于不同开关柜配套的电容传感器指标不一致,造成相序核对误判等问题,提出采用相位差法进行两个高压开关柜之间的相序核对,该方法具有通用性强,判断准确等特点,经实际测试完全满足高压开关柜核相要求.
Abstract
In distribution network,when phase detector is made between two high voltage switchgears,with which the assorted capacitive sensor indicators are inconsistent,some problems like phase sequence detection misjudgment could occur.Therefore,phase difference method is proposed for the phase sequence detection between the two high voltage switchgears.This method has the versatility to judge accurately in phase detection.Actual test shows it could fully meet the phase dection requirements of high voltage switchgear.
