Research on Treatment of Bus Voltage Sudden Change in Equipment operation

During the conversion process of the main transformer low-band feeder bus mode, the main transformer power supply of the bus and the reactive power compensation provided by the equipment on the bus may change, which may cause sudden changes in the bus voltage, which cannot be accurately measured by the operator, which affects voltage sensitivity Precision manufacturing can endanger personal safety in serious cases. The article converts the influence of the main gear position on the bus voltage into the influence of reactive power on the voltage, and quickly analyzes the influence of the operation on the voltage mutation from the same dimension, and incorporates the bus voltage mutation into the switch During the operation check, the five preventions are locked to maintain the voltage stability and ensure the safe production of users.
