[0028] The following is combined with Figs. 1-2 This application is described in further detail.

[0029] The present application discloses a plateau environment simulation test device for electromechanical equipment, comprising: a plateau cabin 3, a multi-environmental test chamber 2, electromechanical equipment 1, and an environmental simulation device.

[0030] like Fig. 1 As shown, the plateau cabin 3 is connected to the exhaust equipment, and the plateau cabin 3 is exhausted by the exhaust equipment so that the plateau cabin can simulate the plateau environmental pressure; the multi-environmental test box 2 is arranged inside the plateau cabin 3, and the multi-environmental test box 2 is a non-airtight structure, and its pressure is consistent with that of the plateau cabin 3; the electromechanical equipment 1 is arranged inside the multi-environmental test box 2; Fig. 2 As shown, the environmental simulation equipment includes multiple ones, and the environmental simulation equipment is arranged inside the multi-environmental test box 2, and multiple plateau environments are simulated by the multiple environmental simulation equipment.

[0031] In a preferred embodiment of the present application, the extraction equipment used to extract air from the plateau chamber 3 is a Roots unit. This efficient and reliable Roots unit extracts air from the plateau chamber 3, creating a low pressure inside the chamber 3 to simulate the low-pressure environment found in a plateau environment. To facilitate installation of the multi-environmental test chamber 2, a first mounting platform is provided within the plateau chamber 3, and the multi-environmental test chamber 2 is mounted on the first mounting platform.

[0032] In the preferred embodiment of the present application, in order to keep the pressure of the multi-environment test box 2 consistent with the plateau cabin 3, a plurality of ventilation grilles 5 are installed on the multi-environment test box 2. In order to facilitate the installation of the electromechanical equipment 1, a second installation platform is also arranged inside the multi-environment test box 2, and the electromechanical equipment 1 is arranged on the second installation platform.

[0033] In the preferred embodiment of the present application, the environment simulation device includes a plurality of devices for simulating different plateau environments. In this embodiment, the environment simulation device includes a dust sprayer 4, an ultraviolet radiation lamp 6, a dehumidification device (not shown in the figure), and a refrigeration and heating device (not shown in the figure). Among them, the dust sprayer 4 is used to simulate the plateau dust environment, and the spray port of the dust sprayer 4 is preferably corresponding to the electromechanical equipment 1; the ultraviolet radiation lamp 6 is used to simulate the plateau ultraviolet radiation environment, and the ultraviolet radiation lamp 6 is installed inside the top box of the multi-environment test box 2; the dehumidification device is used to simulate the plateau humidity environment; the refrigeration and heating device can be an air conditioning unit, and the refrigeration and heating device is used to simulate the plateau day and night temperature difference environment.

[0034] The plateau environment simulation test device for electromechanical equipment of the present application adopts a non-airtight structure for the multi-environment test box 2, and a plurality of environment simulation devices are installed inside, which can realize the simulation of plateau environments such as dust, ultraviolet radiation, humidity, and day and night temperature difference. The multi-environment test box 2 is placed in the plateau cabin 3, which can simulate the plateau pressure environment. The two cabins realize different functions respectively, and their combination can realize the simulation of the plateau environment.

[0035] The plateau environment simulation test device for electromechanical equipment of the present application separately sets up the simulation of the plateau pressure environment through the plateau cabin 3, and the influence of the pressure on the conductive characteristics of the electromechanical equipment 1 takes effect quickly, while the simulation of the plateau pressure needs to use a Roots blower to exhaust air, which consumes a lot of energy. Therefore, after the plateau working characteristic test of the electromechanical equipment 1 using the plateau cabin 3 is completed, the plateau cabin 3 can be closed, and only the multi-environment test box 2 is used for testing. The influence of dust, ultraviolet radiation, humidity, and day and night temperature difference on the electromechanical equipment 1 can be observed only after a long time, and long-term testing is required. The multi-environment test box 2, which realizes the above functions, consumes less energy, is easy to realize, and has a lower cost. In order to test the influence of low pressure and other factors on the electromechanical equipment 1, the plateau cabin 3 and the multi-environment test box 2 can be started at the same time, and the test result can also be observed in a short time, which is low in cost.

[0036] The plateau environment simulation test device for electromechanical equipment of the present application can test the insulation, sealing, and conductive characteristics of the electromechanical equipment 1 according to the characteristics of the plateau environment, such as low pressure, high dust, strong ultraviolet radiation, low humidity, and low temperature, and large day and night temperature difference.

[0037] The high-altitude environment simulation test device of the electromechanical equipment of the application solves the problem of verifying the high-altitude environment adaptability of electromechanical products in a low-altitude laboratory environment, and can be widely applied to high-altitude tests of electromechanical equipment 1 and has universality.

[0038] The above is only a specific embodiment of the application, but the protection scope of the application is not limited thereto, and any person skilled in the art can easily think of changes or replacements within the technical scope disclosed by the application, which should be covered within the protection scope of the application. Therefore, the protection scope of the application should be subject to the protection scope of the claims.
