The application relates to a temperature measuring method, device, computer equipment and storage medium of a switchgear. Among them, the temperature measurement method of the switchgear includes establishing a three-dimensional model of the switchgear; meshing the three-dimensional model to obtain the first grid including the heat dissipation path of the switchgear and the second grid including the outer surface of the busbar of the switchgear. grid; according to the first grid and the second grid, the heat transfer characteristics and flow characteristics of the heat flow are simulated and the simulation results are obtained. According to the heat source of the switchgear, the temperature field control model of the switchgear is established; the temperature field analysis of the simulation results is carried out by using the temperature field control model, and the temperature distribution characteristics of the switchgear are obtained. Through the establishment of the three-dimensional model of the switchgear, the overall model of the switchgear can be analyzed and calculated comprehensively, which improves the accuracy of the analysis results of the temperature field of the switchgear. The heat transfer characteristics and flow characteristics of heat flow are simulated, and the factors affecting heat dissipation are also taken into consideration, further improving the accuracy.
Description
technical field [0001] The present application relates to the technical field of electric power safety, in particular to a temperature measuring method, device, computer equipment and storage medium of a switchgear. Background technique [0002] As an important terminal actuator in the power system, the safe operation of the high-voltage switchgear determines the safety and reliability of the power supply of the power system. In actual operation, heating is a key factor affecting the safe operation of switchgear. In recent years, there have been more and more cases of switchgear failure due to overheating, which has attracted widespread attention from production and operation units and research institutions. The high-voltage switchgear mainly adopts a closed structure, which has poor heat dissipation performance. When working under high voltage and high current conditions, temperature rise will occur, which will seriously affect the operating status of the switchgear. [00...
