摘要
Abstract
The loop resistance characteristic of gas-insulated metal-enclosed switchgear is an important indicator for evaluating its safe operation.However,traditional DC resistance detection methods require power-off operations on power equipment,which leads to re-duced power supply reliability,high operation and maintenance costs,and the inability to obtain equipment operation health data.The existing online monitoring technology is difficult to accurately strip inductive interference.To this end,it collects the AC time-do-main waveforms of the equipment operation,uses the adaptive quantile weighted least squares method to equivalentially calculate the results highly consistent with the DC resistance values,and integrates the geometric cascade forest algorithm to achieve the judgment of the equipment status trend and fault early warning.Ultimately,it realizes the precise assessment and predictive maintenance of the power equipment status without interrupting the power supply.关键词
