Description

Technical Field

[0001] This utility model relates to the field of product quality and performance testing equipment and technology, specifically to an environmental testing device with adjustable irradiance. Background Technology

[0002] Environmental testing is a crucial test for verifying the environmental tolerance of electrical equipment. It determines whether the tested equipment can function normally under specific environmental conditions, serving as a vital criterion for ensuring the product's proper operation in extreme weather conditions. Traditional environmental testing systems place the product under test in an environmental test chamber to assess whether the electrical equipment's performance, such as operation and storage, meets standards under extreme environments. Existing environmental reliability laboratories can provide most of the necessary conditions for alternating damp heat, constant damp heat, and high and low temperature tests. However, for electrical equipment used outdoors, full-spectrum sunlight simulation systems are costly and have strict site requirements. Simulating specific solar irradiance to test the equipment's normal operation and its extreme operating conditions is difficult to achieve while controlling equipment costs. Utility Model Content

Under the premise of reducing the investment cost of laboratory equipment, the irradiance conditions required by relevant standards are met, and the equivalent simulation of environmental conditions with specific solar irradiance is achieved.

The controller includes several circuit breakers, with each row of infrared lamps on the light source panels connected in parallel to one circuit breaker.

[0005] In an optimized configuration, the lower part of the liftable support is provided with a slide module, and the slide module is equipped with two actuators that drive the slider of the slide module to move up and down and translate.

[0006] In the optimized configuration, the infrared lamps are arranged in an 8×4 matrix on the light source board, with 4 rows of 8 lamps each, and a horizontal and vertical spacing of 0.3m. The 8×4 matrix arrangement serves as the basic lamp density unit for testing effectiveness, and the number of infrared lamp groups can be increased according to the size of the sample.

[0007] In an optimized configuration, the controller further includes a microprocessor, a control panel, and a wireless transparent transmission module; each ADC output pin of the microprocessor is connected to a corresponding air switch; the microprocessor is connected to the stepper drivers of the two actuator motors via a pair of INT output pins; and the control panel and the wireless transparent transmission module are bidirectionally connected to the microprocessor via the TXD / RXD / GND serial port power supply pin group.

[0008] Specifically, the microprocessor is an STM32F series microcontroller; the air switch is a BF-228 8-channel electronically controlled air switch; the slide module is a GGP-EB ball screw slide; and the actuator motor is a 57 stepper motor.

[0009] This utility model discloses an environmental testing device with adjustable irradiance.
