[0002] Power equipment mainly includes two categories of power generation equipment and power supply equipment, and the power generation equipment mainly includes power station boilers, steam turbines, gas turbines, water turbines, generators, transformers and the like, and the power supply equipment mainly includes power transmission lines of various voltage levels, transformers, contactors and the like. One of the standards for evaluating power equipment is energy efficiency, which indicates the energy-saving degree and the size of wasted energy of the power equipment.

[0003] The existing power equipment energy efficiency testing platform needs to install the power equipment on the energy efficiency testing platform. When the power equipment is installed and removed, whether the energy efficiency testing device is powered on or not is controlled by a switch, and the protection measures mostly use fuses, protection switches and the like, so that it is inevitable to forget to disconnect the switch, which causes the safety hidden danger that the tester may be electrocuted when connecting the power equipment and the energy efficiency testing device, and the safety of the testing environment is insufficient. The existing related patents / applications, such as the patent / application with the publication number CN111458584A, the name of a kind of power electronic equipment energy efficiency automatic testing platform and testing method, and the patent / application with the publication number CN103683512B, the name of power system energy efficiency testing management system and testing method, mostly do not consider the operation safety problem.

[0004] In addition, the existing power equipment energy efficiency testing platform directly tests the power equipment, and does not consider the energy efficiency change of the power equipment running in different environments, so that the testing environment is single. When the difference between the testing environment and the actual application environment is too large in terms of temperature, ventilation and heat dissipation and the like, there may be a large difference between the measured energy efficiency value and the actual energy efficiency value, the accuracy of the test result is not enough, and the reliability is low.
