The utility model relates to circuit test technical field discloses alternating current turnout control test test appearance, including power module for power supply, inverter module is connected with power module electricity and is used for inverting direct current voltage into alternating voltage, control module, with inverter module electricity connection, acquisition module is connected with control module electricity, and acquisition module includes 5 voltage acquisition channels and 5 current acquisition channels, and voltage acquisition channel and current acquisition channel all are connected with acquisition probe. The utility model, through power module replaces generator drive alternating current switch machine, can make this test appearance to use for a long time continuously, carries out wiring inspection to three -phase five -wire system turnout wiring by control module, to ensure that this test appearance normal work, and further monitor the positioning of turnout, anti -position and four open different positions, solved the inconvenient problem of testing to alternating current turnout.

The utility model provides a kind of test box for door panel and its mechanism test, comprising: outer box, it includes accommodating cavity and outlet, outlet is arranged on the outside of outer box;Built-in function mechanism, it is arranged in accommodating cavity, built-in function includes adjustable transformer and built-in terminal block;External terminal block, it is arranged on the outside of outer box;Control switch group, it is arranged on the outside of outer box, control switch group is electrically connected with built-in function mechanism.This application will control switch group, built-in function mechanism and external terminal block group be set on outer box, and control switch group, built-in function mechanism and the external terminal block group are prewired;When testing, the door panel or door panel mechanism to be measured is respectively wired with external terminal block, and opening or closing can be carried out through control switch group to test door panel or door panel mechanism, solve the problem of testing door panel or mechanism separately.

The invention provides a sunlight simulator as well as an irradiation device and a use method thereof. The irradiation device is connected to the light outlet window of the sunlight simulator and can freely rotate around the light outlet window. The object carrying component of the irradiation device is provided with two symmetrical object carrying cavities which are used for carrying the experimental samples to be irradiated, the requirement that the multiple experimental samples are irradiated at the same time under the same condition is met, and the experiment efficiency is improved. Along with rotation of the irradiation device, the relative irradiation position of the object carrying component and the light emitting window can be adjusted, a more uniform irradiation area can be found, it is guaranteed that the illumination intensity of experimental samples in the two object carrying cavities is consistent, experimental data are more accurate, and experimental results are more objective. According to the irradiation device and the sunlight simulator using method provided by the invention, an implementation path with higher adaptability and higher reliability is provided for related clinical experiment research, the test problem in a sunlight simulator clinical experiment is effectively solved, and the usability and the application range of a sunlight simulator product are greatly improved.
