Analysis and Consideration of an Abnormal Accident of Phase A of Insulated Busbar at Low Voltage Side of 220kV Substation
An insulated tubular bus is widely used in substations because of its many advantages.However,due to the humidity and poor sealing effect,the insulation capacity will be reduced and the breakdown will occur,which brings great potential safety hazards to the production and operation of the main transformer equipment.This paper analyzes and discusses the phase A abnormal accident of the insulated busbar at the low voltage side of the 220kV substation,finds out the influence of the structure and use method of the insulated busbar on its electrical perform-ance through the test,and puts forward preventive measures from the aspects of operation maintenance and personnel quality improvement,which improves the reliability of the equipment and meets the normal operation of the power grid.
