[0001] This utility model relates to the field of EMC testing equipment technology, and in particular to a wall-mounted intelligent DC drop simulator. Background Technology

[0002] A DC voltage drop simulator is a specially designed device used to simulate abnormal conditions such as DC voltage drops and interruptions in a power system. It provides a common basis for evaluating the immunity of electrical and electronic products connected to the low-voltage power grid to voltage transients and short-term interruptions. It plays an important role in assessing the performance of power equipment under abnormal conditions and improving the stability of the power system.

[0003] DC drop simulators are often installed on the ground in professional electromagnetic compatibility (EMC) and power electronics laboratories or testing environments to perform simulation operations. However, the connecting cables may be squeezed and physically damaged due to personnel walking, equipment movement, or pulling during the testing process, resulting in problems such as wear, breakage, or poor contact, which affect their performance and lifespan.

[0004] In conclusion, there is an urgent need for a wall-mounted intelligent DC drop simulator to solve the above problems. Utility Model Content

[0019] Although this invention may be described with respect to a particular application or industry, those skilled in the art will recognize its broader applicability. Those skilled in the art will understand that terms such as "above," "below," "upward," "downward," etc., are used to describe the drawings and not to indicate a limitation on the scope of the invention as defined by the appended claims. Any numerical designations such as "first" or "second" are merely illustrative and not intended to limit the scope of the invention in any way.

[0020] Example: A wall-mounted intelligent DC drop simulator, such as Figures 1-3 As shown, the device includes a mounting plate 1, a placement plate 2, a base plate 3, a DC drop simulator body 4, a sliding plate 5, a fixing plate 6, a baffle 7, and a first elastic element 8. The mounting plate 1 serves as a mounting carrier for the components. A side plate with an I-shape on the front is connected to the lower side of the mounting plate 1. The mounting plate 1 has mounting holes for mounting bolts. The placement plate 2 is placed on the mounting plate 1. Both the mounting plate 1 and the placement plate 2 have J-shaped sides and are connected to each other by an inverted snap-fit ​​mechanism, facilitating the limiting of the DC drop simulator body 4. The base plate 3 is welded to the placement plate 2. A DC drop simulator body 4 is mounted on the base plate 3. A sliding plate 5 is symmetrically welded to the front of the DC drop simulator body 4. A fixing plate 6 is connected to the front of the DC drop simulator body 4. The fixing plate 6 is located to the right of the sliding plate 5. A baffle 7 is slidably connected to the fixing plate 6. Positioning grooves are evenly spaced on the baffle 7. A first elastic element 8 is wound between the fixing plate 6 and the baffle 7. The placement plate 2 is limited to the mounting plate 1 by inverting, thereby realizing the wall-mounted setting of the DC drop simulator body 4.

[0021] like Figure 1 As shown, it also includes a protective plate 9, which is slidably connected to the DC drop simulator body 4. The protective plate 9 is located in front of the right side of the baffle 7.

[0022] like Figure 4 As shown, it also includes a connecting plate 10, a pressing plate 11, and a second elastic element 12. The connecting plates 10 are symmetrically welded to the rear side of the placement plate 2. The two connecting plates 10 are slidably connected to the pressing plates 11 on opposite sides. The front of the two pressing plates 11 on opposite sides is I-shaped and has different widths. The width between the edge of the two pressing plates 11 on opposite sides and the placement plate 2 is equal to the width of the upper side plate of the mounting plate 1, which facilitates fixing the DC drop simulator body 4. The two pressing plates 11 on opposite sides are in contact with the mounting plate 1 and the placement plate 2. The second elastic element 12 is wound between the connecting plate 10 and the pressing plate 11. The pressing plate 11 is fixed to the DC drop simulator body 4 under the elastic force of the second elastic element 12.

[0023] When this device is needed, the mounting plate 1 is installed to the wall using bolts. The pressing plate 11 is moved away from the wall, causing the second elastic element 12 to deform adaptively. The placement plate 2 is placed on the mounting plate 1. The placement plate 2 moves the base plate 3, the DC drop simulator body 4, the sliding plate 5, the fixing plate 6, the baffle 7, the first elastic element 8, the protective plate 9, the connecting plate 10, the pressing plate 11, and the second elastic element 12 to the same horizontal height as the mounting plate 1. The pressing plate 11 is released, and the second elastic element 12 returns to its original shape. The pressing plate 11 resets under the elastic force of the second elastic element 12, limiting the placement plate 2 and thus fixing the DC drop simulator body 4. The protective plate 9 and the baffle 7 are moved to the right in sequence, causing the first elastic element 8 to deform adaptively. The interface on the connecting line is inserted into the interface slot on the DC drop simulator body 4. The baffle 7 is then released. Plate 7 and the first elastic element 8 return to their original state. The baffle 7 resets under the elastic force of the first elastic element 8. The end of the interface on the connecting line is located in the positioning groove on the baffle 7. The baffle 7 can position and protect the interface on the connecting line. After the DC drop simulator body 4 completes the simulation operation, the baffle 7 is moved to the left side of the protective plate 9 according to the above operation. The interface and the interface groove on the DC drop simulator are removed. The baffle 7 is released, the first elastic element 8 returns to its original state, and the baffle 7 resets under the elastic force of the first elastic element 8. The protective plate 9 is moved in the opposite direction to reset. The protective plate 9 protects the baffle 7 and the interface groove on the DC drop simulator body 4. When it is necessary to disassemble the DC drop simulator body 4, the above operation is reversed to make the pressing plate 11 disengage from the upper side plate of the mounting plate 1. The placement plate 2 can be removed from the mounting plate 1.

[0024] Although this disclosure has been described with respect to only a limited number of embodiments, those skilled in the art who benefit from this disclosure will understand that various other embodiments can be devised without departing from the scope of this invention. Therefore, the scope of this invention should be limited only by the appended claims.
