Description

Technical Field

[0001] This utility model relates to the field of structural technology of aging cabinets, specifically to an inverter aging test cabinet. Background Technology

[0002] Currently, an inverter is a converter that transforms direct current (DC) into alternating current (AC). The main body of an inverter is the inverter circuit, which also includes control, protection, and filtering circuits. An inverter is a type of transformer; it is essentially a voltage inversion process, similar to a converter. Inverters are widely used in office equipment, household appliances, or applications requiring battery power. Inverters are mainly divided into two categories: one based on the waveform characteristics, and the other based on the source current characteristics. Inverters are characterized by high conversion efficiency, fast start-up, good safety performance, excellent physical properties, and strong adaptability and stability under heavy loads.

[0003] In the prior art, such as the aging cabinet for inverter power-feed aging testing with application publication number CN215525983U, there is an aging cabinet including a power supply cabinet, an inverter aging cabinet, and a back panel. The power supply cabinet and the inverter aging cabinet are mounted on the back panel. A power supply is installed inside the power supply cabinet to power the aging cabinet. The power supply cabinet, the inverter aging cabinet, and the back panel are arranged in a stepped manner. The inverter aging cabinet has a first side with multiple power ports for connecting external devices under test. The aging cabinet of this utility model has an inverter aging cabinet and a power supply cabinet... The lower-level splicing structure centrally places the inverter aging cabinets on the upper level, facilitating the replacement of the equipment to be tested. The stepped inverter aging cabinet not only makes it easier to replace the test equipment but also facilitates open heat dissipation. However, in use, the inverters are placed on the table, and each inverter needs to be manually powered on one by one, which is a rather troublesome and cumbersome process. It is also inconvenient to power on multiple inverters at the same time. Furthermore, the patent does not include any inverter fixing devices, making it inconvenient to secure the inverters. Utility Model Content

[0004] This utility model proposes an inverter aging test cabinet, which solves the problem that inverter aging test cabinets in related technologies are inconvenient for simultaneously connecting multiple inverters to power and fixing the inverters.

[0005] The technical solution of this utility model is as follows:

[0006] An inverter aging test cabinet includes a test cabinet shell, inside which a test chamber is formed. A transparent protective door is hinged to one side of the front of the test chamber. A first mounting block is fixed to the top of the test chamber, and a second mounting block is fixed to the inner side. A first electric telescopic rod is fixedly connected to both ends of the bottom of the first mounting block, and a fixing plate is connected to the bottom of the first electric telescopic rod. A second electric telescopic rod is fixed to both ends of the second mounting block in a horizontal direction. A synchronization plate is fixedly connected to the outer end of each second electric telescopic rod, and several equally spaced electrical plugs are installed on the synchronization plate.

[0007] As a further improvement, a fixed shaft is fixedly connected to the upper and lower ends of one side of the transparent protective door, and the fixed shaft is rotatably connected to the outer shell of the test cabinet.

[0008] In a further improvement, a circular hole is provided inside the outer shell of the test cabinet, and the fixing shaft is nested inside the circular hole.

[0009] In a further improvement, the electrical plug is electrically connected to an electrical control cabinet, which is equipped with a display screen and an operation keyboard.

[0010] A further improvement is that the fixing plate is a padded fixing plate.

[0011] Further improvements include the formation of several fixing grooves at the bottom of the test chamber.

[0012] As a further improvement, a protective net is installed on one side of the test cabinet shell.

[0013] The working principle and beneficial effects of this utility model are as follows:

[0014] 1. In this utility model, the first electric telescopic rod, soft pad fixing plate and other structures are set up, and the first mounting block is pushed down to push the first electric telescopic rod through the control of PLC and operation keyboard. This causes the soft pad fixing plate to fix the inverter placed on the placement table. The soft pad fixing plate can prevent the inverter surface from being scratched, and achieves the effect of conveniently fixing the inverter.

[0015] 2. In this utility model, the second electric telescopic rod and the electric plug are designed to allow the second electric telescopic rod to push the synchronous plate outward through the operation keyboard and the second telescopic block connected to the power supply. The synchronous plate drives the electric plug to connect the inverter to power. With the power plug connected to the power supply, the inverter can be tested for aging, thus achieving the effect of conveniently connecting multiple inverters to the power supply at the same time.

[0023] Example 1

[0024] like Figures 1-4As shown, this embodiment proposes an inverter aging test cabinet, including a test cabinet shell 1 and an electrical control cabinet 4. A fixed shaft 15 is rotatably mounted inside the inverter aging test cabinet shell 1. A transparent protective door 3 is fixedly connected to the fixed shaft 15 by screws. A door handle 14 is fixedly connected to the transparent protective door 3 by screws. A display screen 5 is mounted on the inverter aging test cabinet electrical control cabinet 4. An operation keyboard 6 is provided on the inverter aging test cabinet electrical control cabinet 4. A first mounting block 8 and a second mounting block 16 are respectively installed inside the inverter aging test cabinet electrical control cabinet 4. Two symmetrically arranged mounting blocks 16 are slidably assembled inside the first mounting block 8. The bottom of the first electric telescopic rod 9 and the two inverter aging test cabinets are fixedly connected to a soft pad fixing plate 10 by screws. The interior of the electrical control cabinet 4 of the inverter aging test cabinet is fixedly connected to a placement platform 7 by screws. The interior of the placement platform 7 of the inverter aging test cabinet is provided with several evenly distributed fixing grooves 11. Through the arrangement of the first electric telescopic rod 9, the soft pad fixing plate 10 and other structures, and through the control of the operation keyboard 6, the first mounting block 8 pushes the first electric telescopic rod 9 downward, which drives the soft pad fixing plate 10 to fix the inverter placed on the placement platform 7. The soft pad fixing plate 10 can prevent the surface of the inverter from being scratched, and achieve the effect of conveniently fixing the inverter.

[0025] like Figure 3 As shown, the inverter aging test cabinet housing 1 has a round hole inside, and the inverter aging test cabinet fixing shaft 15 is nested inside the round hole of the inverter aging test cabinet.

[0026] In this embodiment, when the operator conducts the inverter aging test, they first turn on the power supply, turn on the electrical control cabinet 4, and operate the keyboard 6 and display screen 5 to place the inverter in the fixing groove 11. Through the setting of the first electric telescopic rod 9, the soft pad fixing plate 10 and other structures, and the control of the keyboard 6, the first mounting block 8 pushes the first electric telescopic rod 9 downward, which drives the soft pad fixing plate 10 to fix the inverter placed on the placement platform 7. The soft pad fixing plate 10 can prevent the inverter surface from being scratched, and achieves the effect of conveniently fixing the inverter.

[0027] Example 2

[0028] Based on the same concept as Embodiment 1 above, this embodiment also proposes an inverter aging test cabinet. Two symmetrically arranged second electric telescopic rods 17 are slidably mounted inside the second mounting block 16 of the inverter aging test cabinet. A synchronization plate 18 is fixedly connected to both second electric telescopic rods 17 by screws. Several equally spaced electrical plugs 19 are installed on the synchronization plate 18. Through the arrangement of the second electric telescopic rods 17, electrical plugs 19, etc., and by operating the keyboard 6 and the electrically connected second telescopic block, the second electric telescopic rods 17 can push the synchronization plate 18 outwards. The synchronization plate 18 drives the electrical plugs 19 to connect the inverters to power. With the electrical plugs 19 connected to power, aging tests can be performed on the inverters, achieving the effect of conveniently connecting multiple inverters to power simultaneously.

[0029] like Figure 1 As shown, the inverter aging test cabinet housing 1 has a groove inside, and the inverter aging test cabinet synchronization plate 18 is nested inside the groove of the inverter aging test cabinet.

[0030] In this embodiment, by setting up structures such as the second electric telescopic rod 17 and the electric plug 19, and by operating the keypad 6 and the second telescopic block which is electrically connected, the second electric telescopic rod 17 can push the synchronization plate 18 outward. The synchronization plate 18 drives the electric plug 19 to connect the inverter to power. With the electric plug 19 connected to power, the inverter can be subjected to aging tests. This achieves the effect of conveniently connecting multiple inverters to power at the same time, saving time and avoiding the waste of a lot of time by plugging and unplugging each plug one by one.

[0031] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model.
