Description

Collapse test device power recycling system

This creation belongs to the technical field of collapse testing. In particular, the battery device replaces the conventional dummy load, and the power recovery cycle is reused, which has a large amount of power saving resources and achieves energy saving purposes.

Under the continuous research and development and innovation of technology, many of the previous work has been completely replaced by electronic components (products). Since electronic components (products) are manufactured through multiple processing procedures, in order to ensure product quality, the industry is electronically After the component (product) is manufactured, the inspection operation is performed to detect whether the electronic component is damaged during the manufacturing process, and then the defective product is detected. The so-called collapse test (BURN-IN TEST or burn test), the collapse test is mostly carried out in a heating furnace to place the test object in a higher temperature environment to perform the test operation, and the more severe test conditions Pre-detected products that are on the verge of damage or poor quality, and enter the stable period with the product passing the pre-expiration period, and obtain stable product characteristics when used by consumers.

The conventional collapse test device is shown in Figure 1, which mainly includes a collapsed cabinet (A), a collapsed cabinet (A) with a ventilation system (B), and a collapsed cabinet (A) with a test device. (C), one end of the test device (C) is connected to the AC power distribution board (D), the other end is connected to the dummy load (E), and the AC power distribution board (D) is connected to the mains system (F). The above ventilation system is usually set up for a long time because of the test time. The temperature inside the collapsed cabinet will continue to rise. Therefore, a ventilation system is needed to remove the hot air and to add low temperature outside air to maintain the collapse. The test condition temperature in the cabinet (such as 50 ± 10 ° C). Mains AC The AC power distribution board supplies power to the test device, and the test device is used to set each electronic component or device to be tested, and then connected to the dummy load. The dummy load is generally composed of a resistor, and the heat is generated by the resistor to increase the temperature of the collapsed cabinet, thereby achieving The collapse should be tested. Take the power supply as an example, China Patent No. M290246 "Power Supply Burner Test Box" patent (announcement date, May 01, 2006), which includes multiple test layers, multiple test backplanes, multiple electronic analog power loads and one a control unit, wherein the test backplanes are respectively disposed on the test layers, and are coupled to the electronic analog power loads to form an electrical path, wherein the test backplanes are respectively connected to the power supply to be tested, and the control unit includes a temperature controller for controlling the temperature in the test chamber of the power supply, and an AC power supply for supplying power to the power supply tester, the improvement being: The test backplane includes at least two power supply test backplanes.

As mentioned earlier, the collapse test is performed by connecting a dummy at the output of the test device. Loads can be classified into passive loads and active loads depending on the type. The passive load is mainly composed of a resistive load box. The passive load is unstable due to factors such as the output voltage of the converter to be tested, the temperature coefficient of the resistor, and no feedback control. The active electronic load is a first-level converter between the converter to be tested and the resistance load box. The control of the converter can keep the test current stable and dynamically change the test current. Therefore, it is active in the industry. Electronic load is the mainstream. However, whether it is a passive load or an active electronic load, a resistive load box is required. In addition to the heat consumption of the electric resistance load box, a fan is additionally required to assist the heat dissipation, which often causes the test equipment to be bulky. And additional power loss is required. As can be seen from the above, it takes a lot of power to test for the reliability and quality of the product (there are a lot of large-power electronic devices or parts, and the power consumption is large, and the 2-3 fans of the ventilation system also consume High power) and will increase the carbon footprint of the product, thus not meeting low carbon and The environmental protection concept of energy conservation will increase production costs. Therefore, it has been proposed in many documents to use a collapse test device with electrical energy recovery to recycle electrical energy. In addition to greatly reducing the cost and time of electricity required for the collapse test, this can meet the environmental protection concept of energy saving and low carbon. For example, China's I443960 patent "photovoltaic recovery system as an auxiliary power supply for illuminating source burning machine test" is applicable to the illuminating source burning machine test to reduce the power required by a mains system, including: at least one illuminating mode The group is continuously illuminated for a burn-in test; at least one solar module is disposed above the light-emitting module to receive a light source emitted by the light-emitting module; and a photoelectric conversion module is connected to the solar energy a module for converting the light source into a recovery power source; and a power connection module connecting the light module, the photoelectric conversion module and the utility system to one of the recovered power source and the utility system The commercial power is simultaneously supplied to the lighting module. However, its structure is relatively complicated, and the poor efficiency of light energy conversion is lacking. This lack is a difficult problem to be overcome in the industry.

In view of the lack of the above-mentioned conventional technology, this creative researcher has accumulated many years of practical knowledge in the design and construction of energy-saving products. After continuous research and improvement, the creation of this creation has been successful and made known to the world.

The electric disk replaces the conventional dummy load by the battery device, and the power recovery cycle is reused, which has the effect of saving a large amount of power resources and achieving energy saving purposes.

Another main purpose of the present invention is to provide a power recovery and reuse system for a collapse test device, which mainly comprises a collapse chamber, a test device in the collapse cabinet, a ventilation system connected to the collapse cabinet, and an AC power distribution panel connected to the test device.
