一种无需拆卸接地排的GIS主回路电阻快速测量方法
A Rapid Measurement Method for GIS Main Circuit Resistance Without Disassembling the Grounding Busbars
摘要
Abstract
To address the issues such as the need to remove and reinstall grounding busbars in tradi-tional gas-insulated switchgear(GIS)main circuit electrical equipment resistance testing,this paper pro-poses a method for rapidly measuring the single-phase contact resistance inside GIS without dismantling the grounding busbars.Using each grounding busbar as a test point,an excitation power supply are applied twice between the grounding busbars,and the corresponding electrical quantities at each test point are re-corded.Based on the circuit topology,a system of loop current equations is established.By substituting the electrical quantities obtained from the two measurements into these equations,the resistance values of each electrical equipment can be determined.Simulations results indicate that a theoretical error is 0.Consider-ing the maximum inherent error of the measuring instruments,this method enables the synchronous resist-ance measurement of all single-phase equipment in GIS,with the relative error meeting the requirements of on-site measurement.It effectively avoids the safety risks associated with dismantling grounding bus-bars,and offers advantages such as operational simplicity and reduced workload.关键词
