| Abstract: | Through the analysis of the principle, technology and structure of the insulation cabinet, the design of the insulation cabinet of the outdoor frequency conversion controller is completed, which solves the problem that the frequency conversion controller of the wind and solar water pumping equipment is easy to freeze in winter. In the development of a new type outdoor frequency conversion controller insulation cabinet, its thermal insulation effect is analyzed by means of model simulation and test verification, and the experimental analysis is made. The results show that the linear model of the length of self-limiting temperature tracing tropical zone and the ambient temperature is L=-0.062T∞+0.65, and the standard deviation is 0.804, and the precision is high. The ideal heating mode of the insulation cabinet is determined to be the length of the self-limiting temperature tracing tropical zone of 2.2 m and the heating time of 25 minutes. The analysis shows that the self-limiting temperature tracing tropical zone used in the insulation cabinet can effectively improve the temperature inside the cabinet and ensure the normal opening and closing of the controller, which has better practical application effect. As a result, it is of great significance to improve the water-supply guarantee rate of wind energy and solar energy water-supply equipment in winter in high, cold and remote areas. |
