[0032] See also Figure 1-Figure 3 , the present invention provides a technical solution:
[0033] A power supply equipment aging cabinet, comprising: a power distribution device, a power supply device, and a load device;
[0034] The power distribution device includes an input module, a protection module, a first relay module, a contact module, and an output module, which are used to connect to an external high and low temperature aging room and supply power to the control modules of the power supply device and the load device respectively.

[0036] A main power switch is connected in series between the input module and the air switch. It is a single-pole multi-throw switch. The specific model can be the Schneider Electric IZMX series. The three-phase aviation plug of the input module has five terminals, namely three phase terminals, one neutral terminal and one ground terminal. The three phase terminals are connected to three different phase lines, the center line terminal is connected to the neutral line, and the ground terminal is connected to the ground line. The three phase lines and the neutral line are all connected to the main power switch and the protection module for control. The three phase lines are all connected to the first relay module, and are respectively connected to one of the terminals in the aircraft carrier of the first output unit. The neutral line is not connected to the first relay module, but is divided into three paths and connected to another terminal in the aircraft carrier of the first output unit, and then the last terminal in the aircraft carrier of the first output unit is externally connected to the ground wire.
[0037] This modular construction method generally uses modules and equipment with a variety of optional accessories and flexible configuration options, which are easy to integrate into different electrical systems and can adapt to diverse testing needs. The use of safety equipment such as safety relays and emergency stop switches improves the safety of the system and can quickly cut off the power supply in an emergency to protect equipment and personnel. The programmable power supply and delay relay allow the system to be adjusted and controlled according to different test scenarios, increasing the accuracy and controllability of the test. At the same time, by selecting high-performance power and load modules, it ensures that the equipment under test can get a stable power supply during the aging test, thereby obtaining more accurate test results.
[0038] Standardized interfaces and connection methods make the system integration process simple and fast, and facilitate cooperation with other devices and modules. The modular design that is easy to replace and upgrade reduces the difficulty and cost of equipment maintenance, thereby increasing the service life of the system.
[0039] The input module, protection module, contact module, and output module are connected in series in sequence using three-phase lines. The first relay module is connected in parallel with one of the phase lines of the three-phase line. The input end of the power supply device is electrically connected to the output module of the distribution device, and the output end is electrically connected to the load device for powering the drive module of the load device. The load device includes a control module and a drive module. The control module is electrically connected to the drive module for controlling the opening and closing of the drive module. The drive module is used to connect to the product to be tested and provide power.
[0040] The input end of the first relay module is electrically connected to one of the phase lines of the three-phase line, and the output end is electrically connected to the contact module, which is used to control the contact module; a reset button is connected in series between the port on one side of the first relay module and the contact module, and the specific model can be an ABB MCBH series button, and the port on the other side is connected in series with an emergency stop switch, and the specific model can be an Eaton M22 emergency stop button.
[0041] The input ends of the three aircraft carriers in the first output unit are electrically connected to the three phases of the three-phase line, and the output ends are electrically connected to the input ends of the three programmable power supplies. The two groups of connectors in the second output unit are connected in parallel, and the ports of one group of connectors are electrically connected to one of the phases of the three-phase line through the switching power supply, and are also electrically connected to the six groups of delay relays in the control module in the load device, so as to provide working voltage for the six groups of delay relays; the ports of the other group of connectors are connected in series with a rotary button, and two wires are led out to be electrically connected to the external high and low temperature aging room, which can be connected to the socket, power supply interface, or other external power supply of the external high and low temperature aging room, which can be set by the user. The model of the rotary button can be the Schneider Electric Harmony XB5 series. The knob switch has two gears: Hand and Oven. When the knob switch is rotated to the Hand gear, the connector connected to the high and low temperature aging room is in an open circuit state as a whole, and the power supply for the product to be tested is controlled by the power supply equipment aging cabinet itself. When it is rotated to the Oven gear, the power supply for the product to be tested is controlled by the high and low temperature aging room.
[0042] The use of clear control strategies and operation interfaces allows users to intuitively operate the system while providing necessary safety measures to avoid losses caused by misoperation. At the same time, through flexible power and load configuration, the system can adapt to different aging test requirements and provide accurate and reliable test results. Moreover, the modular design allows the system to be quickly deployed and expanded, and can adapt to changing technical requirements and market demands.
[0043] The 6 groups of delay relays of the control module in the load device are connected in parallel with each other, and the 16 groups of power supply modules of the drive module are divided into 3 drive branches. The first drive branch includes 6 groups of power supply modules connected in series, and the second drive branch and the third drive branch each include 5 groups of power supply modules connected in series with each other.
[0044] In the three driving branches, the first power supply module of each driving branch is electrically connected to the output end of the programmable power supply;
[0045] The first five groups of delay relays in the control module of the load device, the output end of each group of delay relays are electrically connected to the power supply modules on the three drive branches, and the output end of each group of delay relays is connected in parallel with the power supply modules on three different drive branches. The output end of the sixth group of delay relays in the control module of the load device is electrically connected to the sixth group of power supply modules on the first drive branch. This connection method is equivalent to forming a matrix of power supply modules. In the horizontal direction, the three drive branch power supply modules are controlled by three groups of power supply devices respectively. By adjusting the power supply device, that is, the preset voltage and current values in the programmable power supply, the output voltage value and output current value of the power supply module are controlled, thereby changing the aging environment of the product to be tested. In the vertical direction, each group of delay relays provides working voltage for the three groups of power supply modules for control, and the power supply modules in each row do not affect each other. And this layout connection method can number each power supply module, which can quickly locate the problem point in the later maintenance work, and facilitate maintenance personnel to repair.
[0046] By dividing 16 power supply modules into 3 drive branches and directly connecting the first power supply module of each branch to the programmable power supply, flexible and precise power distribution is achieved to adapt to different load requirements. The use of delay relays not only enables the system to accurately manage the load and improve the accuracy of testing and operation, but also reduces the impact of current shocks on the equipment, thereby extending the service life of the equipment and improving the safety of the system.
[0047] The specific operation process of the present invention is: connect the product to be tested with the output end of the power supply module one by one, pull down the power gate of the high and low temperature aging room, connect three-phase power to the power distribution device of the power equipment aging cabinet, turn on the main power switch and the air switch, adjust the knob switch to the Oven gear, and then press the reset button. At this time, the switching power supply provides 24V working voltage to 6 groups of delay relays through the connector. The 6 groups of delay relays start all power supply modules. Finally, set the voltage and current values of the 3 programmable power supplies according to the needs, and output them to the product to be tested through the power supply module.
[0048] In summary, the power supply equipment aging cabinet of the present invention realizes simple system integration and rapid deployment through modular design and standardized interfaces, significantly reducing the difficulty and cost of maintenance. Utilizing programmable power supplies and time-delay relays, the system can flexibly adjust the power output according to different test requirements, thereby improving the accuracy and reliability of the test. By dividing the power supply module into multiple drive branches, the system realizes precise power distribution and adapts to diverse load requirements, while reducing the impact of current shocks on equipment and extending the life of the equipment. The use of safety relays and emergency stop switches improves the safety of the system, ensuring that it can respond quickly and cut off the power supply in an emergency to protect the safety of equipment and personnel. These advantages enable the present invention to provide excellent performance and safety assurance in harsh environments such as high and low temperature aging tests.
