Description

Technical Field

[0001] The utility model relates to the technical field of solid capacitor experiments, in particular to an impregnation experiment device for solid capacitors. Background Technique

[0002] The impregnation of capacitor cores is an important process for aluminum solid capacitors. The impregnation effect directly affects the performance of the finished capacitors. Conventionally, a customized vacuum impregnation box is used for impregnation experiments.

[0003] In the impregnation process, the impregnation material liquid is first poured into a glass or PTFE impregnation tank, and the capacitor cores are hung on the wall of the impregnation tank for impregnation. For specific experimental purposes, different capacitor cores need to be used to impregnate the same material. Different elementary units are impregnated simultaneously in the same impregnation tank. Since the specifications and lengths of different impregnation cores are inconsistent, the capacitor cores will float and tilt to varying degrees during the impregnation process. In addition, for comparison requirements, different elementary units also need to be immersed to different depths. The conventional impregnation rack lacks the necessary adjustment function, which will affect the effect of the impregnation experiment. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the defects existing in the prior art, and to propose an impregnation experiment device for solid capacitors.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] An impregnation experiment device for solid capacitors includes vertical legs on both sides. The tops of the vertical legs are connected by a cross bar frame. A number of spaced overhead blocks are arranged at the center of the top surface of the cross bar frame. A disc assembly is arranged on the top of the overhead block. The disc assembly is suspended above the cross bar frame through the overhead block. The inside of the disc assembly is hollow and a sliding rod is inserted vertically. A fixed clamp for clamping the elementary unit is arranged at the bottom of the sliding rod. A fixed seat is arranged at the top of the sliding rod. Two limiting support arms are rotatably installed in the fixed seat. The limiting support arms swing downward, and the barbs designed at their respective lower ends are respectively clamped in the disc assembly. An installation frame is erected above the cross bar frame. A number of vertical rods are inserted into the installation frame, and the lower ends of each vertical rod are respectively butted against the corresponding fixed seat below.

[0007] In a preferred technical scheme, the disc assembly includes a number of identical frustum-shaped disc bodies, and each frustum-shaped disc body is stacked up and down in sequence to form an integral body.

[0008] In a preferred technical scheme, a vertical hole for inserting the sliding rod is reserved at the center of the disc assembly, and guiding vertical grooves are respectively opened on both sides of the hole wall of the vertical hole.

[0009] In a preferred technical solution, a slot hole contour consistent with the center of the disc assembly is formed in the center of the overhead block.

[0010] In a preferred technical solution, guiding slide bars adapted to the guiding vertical slots at the center of the disc assembly are respectively arranged on both sides of the rod body of the sliding rod.

[0011] In a preferred technical solution, a spring is sleeved on the rod body of the vertical rod. The lower end of the spring is connected to the lower fixing seat, and the upper end of the spring is connected to the top wall of the mounting bracket.

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0020] In this embodiment, with reference to Figures 1-3, A solid-state capacitor impregnation experiment device, including vertical legs 1 on both sides. The tops of the vertical legs 1 are connected by a cross bar frame 2. Several overhead blocks 3 arranged at intervals are provided at the center of the top surface of the cross bar frame 2. A disc assembly 4 is provided on the top of the overhead block 3. The disc assembly 4 is suspended above the cross bar frame 2 through the overhead block 3.

[0021] The disc assembly 4 includes several identical frustum-shaped discs. Each frustum-shaped disc is stacked vertically in sequence to form a whole. The inside of the disc assembly 4 is hollow and a sliding rod 6 is inserted vertically. As shown in the appendix Figure 3 As shown, a vertical hole for inserting the sliding rod 6 is reserved at the center of the disc assembly 4, and guide vertical grooves are respectively opened on both sides of the hole wall of the vertical hole. Guide sliding strips 61 adapted to the guide vertical grooves at the center of the disc assembly 4 are respectively provided on both sides of the rod body of the sliding rod 6.

[0022] Here, a slot hole contour consistent with the center of the disc assembly 4 is opened at the center of the overhead block 3. It can be seen from this that the sliding rod 6 can sequentially penetrate through the disc assembly 4, the overhead block 3, and the cross bar frame 2 vertically until it is inserted below the cross bar frame 2. A fixing clip 10 for clamping the element 11 is provided at the bottom of the sliding rod 6.

[0023] A fixing seat 7 is provided at the top of the sliding rod 6. Two limiting support arms 71 are rotatably installed in the fixing seat 7. The limiting support arms 71 swing downward, and barbs designed at their respective lower ends are respectively clamped in the disc assembly 4. It should be particularly noted that the limiting support arms 71 are symmetrically structured and vertically distributed on both sides along the sliding rod 6.

[0024] The purpose of designing the overhead block 3 is to ensure that when the limiting support arms 71 are in the lowest position, the barbs at the lower ends of the limiting support arms 71 will not touch the cross bar frame 2, that is, the limiting support arms 71 can rotate freely even when in the lowest position.

[0025] An installation frame 5 is erected above the cross bar frame 2. The installation frame 5 is an inverted U-shaped structure. The installation frame 5 is erected above the cross bar frame 2 through its two arms. Several vertical rods 8 are inserted into the installation frame 5. The lower ends of each vertical rod 8 are respectively butted against the corresponding fixing seat 7 below. It should be added that a spring 9 is sleeved on the rod body of the vertical rod 8. The lower end of the spring 9 is connected to the fixing seat 7 below, and the upper end of the spring 9 is connected to the top wall of the installation frame 5.

[0026] In practical applications, as shown in the appendix Figure 1 or as shown in the appendix Figure 2For the states of the element 11 shown, for elements 11 with different lengths, it is possible to choose to fix them at different depths or at the same depth. The specific adjustment method is that the staff presses down the top of the vertical rod 8 to control the downward sliding of the sliding rod 6. During the downward sliding of the sliding rod 6 and the fixed seat 7, the two limiting arms 71 will automatically be clamped on a corresponding conical disk body of a certain layer of the disk assembly 4. Finally, it should be noted that when the vertical rod 8 is pushed downward, the spring 9 is in a stretched state, and the fixed seat 7 connected to the spring 9 has a tendency to slide upward. Moreover, the two limiting arms 71 of the fixed seat 7 are just clamped in the corresponding conical disk body of a certain layer. Therefore, it is ensured that the positions of the upper vertical rod 8 and the lower sliding rod 6 are relatively fixed, and thus the element 11 can be fixed at a specified height.

[0027] The vertical leg 1 is placed into the impregnation tank. After the position of the element 11 is determined, the vacuum valve can be opened to conduct the impregnation experiment. Such an experiment can improve the efficiency, and the effect of the impregnation experiment is also greatly improved.

[0028] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
