110 kV 电阻接地系统电气设备适应性研究及试验
Research on Adaptability of Electrical Equipment of 110 kV Resistance Grounding System and Experiment
摘要
Abstract
1 10 kV neutral resistance grounding system is able to eliminate voltage sag on the load side due to the single-phase grounding fault.At the same time,however,the voltage of the neutral point and non-fault phase voltage to ground will be elevated.So part of the 1 10 kV electrical equipment used in the original neutral direct grounding system cannot be used directly in the 1 10 kV neutral resistance grounding system.The adaptability of electrical equipment for the 1 10 kV neutral resistance grounding system is studied through theoretical analysis and simulation.Suggestions are made for selection of 1 10 kV electrical equipments.And a field experiment on the 1 10 kV neutral resistance grounding system is performed to prove the feasibility and excellence of 1 10 kV neutral resistance grounding system.
