A high-voltage switchgear temperature rise real-time simulation and state evaluation method and system

Abstract

The present application belongs to the field of high-voltage switchgear and high-voltage electrical appliance operation and maintenance, and particularly relates to a high-voltage switchgear temperature rise real-time simulation and state evaluation method and system. The present application simulates the temperature of each position inside the high-voltage switchgear through a thermal network model and corresponding thermal network equation. The simulation process principle is simple, and the calculation amount of parameters involved is small. Therefore, the processor of the operation and maintenance platform can complete the calculation and output the simulation result within seconds, ensuring the real-time of the simulation result and saving the operation cost. At the same time, the temperature of the high-voltage switchgear shell is simulated to provide a real-time guarantee for the theoretical value of the normal temperature at each moment under the equipment operating state. When the temperature of the equipment is abnormal, the theoretical value and the actual value can be compared in time to obtain and take measures, so that the real-time evaluation of the equipment temperature rise state can be realized without real-time detection of the equipment temperature rise state on the premise of saving time and effort in the field operation and avoiding the problem that defects cannot be found in time.
