汇控柜电机控制回路中电阻烧毁原因浅析

Analysis on the Reason of Resistance Burned in the Control Loop of Control Cubicle Motor

以电压等级为220kV GIS、油泵电机控制回路控制电压为AC220V的汇控柜为例,通过电路分析、建立数学模型、电路计算等步骤,分析了该回路中电阻烧毁的真正原因,为提高油泵电机控制回路的可靠性、改进控制电路提供了依据。

The article,With the control cubicle which the voltage of oil pump motor control loop as AC220V, voltage rating as 220kV GIS for an example. Based on the analysis of the circuit, established mathematical model, the circuit calculation, preliminary the reason for resistance burned in this loop is anaylyzed reference for improving the reliability of the oil pump motor control loop and improving control circuit.
