[0001] This invention relates to the field of capacitor technology, and more particularly to a pillar-type capacitor. Background Technology

[0002] To ensure the stability of the pillar-type capacitor structure, the existing structure has a strong overall connection between the various components of the capacitor, which makes the assembly and disassembly of the capacitor more troublesome, which is not conducive to the later maintenance of the product.

[0003] When used indoors, the adaptability and applicability of the capacitors are limited because workers cannot quickly adjust the height of the pillar-mounted capacitors. This application addresses the question of how to flexibly change the number of capacitor banks installed according to the size of the indoor space to improve the applicability of the capacitors.

[0007] The top of the locking box is designed as an opening. The interior of the locking box has a cross-shaped horizontal groove and a vertical groove. Two symmetrically distributed movable blocks are arranged in the horizontal groove. The movable blocks are T-shaped. The T-shaped ends of the movable blocks extend into the vertical groove and slide elastically along the longitudinal direction. The top of the T-shaped ends of the movable blocks is provided with mounting blocks. The opposing surfaces of the two mounting blocks are respectively provided with insert blocks. The front ends of the opposing inner surfaces of the two movable blocks are respectively provided with notches.

[0008] A rotating column and a fixed cylinder are provided between the two movable blocks. The outer surface of the rotating column near the front end is provided with a spiral groove, and the front end face of the rotating column is provided with an end post. The rotating column is rotatably mounted on the front inner wall of the transverse groove through its front end post. The fixed cylinder is fixedly mounted on the rear inner wall of the transverse groove. The fixed cylinder is coaxial with the rotating column, and the tail end of the rotating column is inserted into the fixed cylinder.

[0009] A sliding ring is fitted on the column body of the rotating column. The sliding ring slides along the length of the column body. The sliding ring abuts against the inner surface of the movable blocks on both sides. A ball bearing is provided on the inner wall of the sliding ring. The ball bearing is built into the spiral groove and slides along it.

[0010] A bushing that rotates coaxially with the end post is fitted onto the end post, and a moving contact is installed on the bushing.

[0011] The capacitor assembly has a connecting post at its bottom. The lower end of the connecting post is inserted into the locking box. The bottom end of the connecting post is placed on two movable blocks. Slots that are compatible with the insert blocks are opened on both sides of the connecting post. At the same time, a stationary contact that is compatible with the moving contact is provided on the side of the connecting post opposite the end post.

[0012] In a preferred embodiment, an equalizing ball is provided on the top of the equalizing ring.

[0013] In a preferred embodiment, multiple capacitor assemblies are arranged on the same layer, and each capacitor assembly has a locking box at its bottom.

[0014] In a preferred embodiment, the diameter of the sliding ring is larger than the diameter of the fixed cylinder.

[0015] In a preferred embodiment, the rear side of the sliding ring is provided with a plurality of connecting rods, the connecting rods extending rearward and protruding outward from the locking box, and the ends of the connecting rods are all fixedly mounted on the same end block.

[0016] In a preferred embodiment, the rear side wall of the transverse groove inside the locking box has a perforation for the connecting rod to slide through.

[0024] 3. The moving contact rotates to contact the stationary contact. Through the disconnection or electrical connection formed between the moving and stationary contacts, current signals can be effectively transmitted, while also providing a high level of safety during assembly and disassembly.

[0025] In summary, the pillar-type capacitor proposed in this solution solves the problems of inconvenient installation and disassembly, and limited applicability due to the inconvenience of height adjustment in pillar-type capacitor products.

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0034] In this embodiment, refer to the appendix. Figure 1 A pillar-type capacitor includes an equalizing ring 1 and an insulating base 5. The top of the equalizing ring 1 is provided with an equalizing ball 30, and the top of the insulating base 5 is provided with a low-voltage terminal 6. The bottom of the equalizing ring 1 is mounted with a support seat 3 via a support column 2. The top center of the support seat 3 is provided with a high-voltage terminal 31, and the bottom of the support seat 3 is provided with a multilayer capacitor assembly 7.

[0035] Adjacent capacitor assemblies 7 are connected by locking discs 4. Locking boxes 8 are respectively installed on the locking discs 4 and the insulating base 5. Figure 1 Explain the connection relationships:

[0036] The bottom of the capacitor assembly 7 is mounted on the insulating base 5 via the locking box 8, and the top is fixedly mounted on the bottom of the locking disc 4 above.

[0037] The capacitor assembly 7 in the middle layer is mounted on the lower locking plate 4 at the bottom via the locking box 8, and its top is fixedly mounted on the bottom of the upper locking plate 4;

[0038] The capacitor assembly 7 at the top layer is mounted on the locking plate 4 below via the locking box 8 at the bottom and on the bottom of the support base 3 above at the top.

[0039] It should be noted that there are multiple capacitor assemblies 7 on the same layer, and each capacitor assembly 7 has a locking box 8 at its bottom.

[0040] See attached document Figure 2 -Appendix Figure 5 The structure of the locking box 8 is described in detail below. As shown in the attached figure, the top of the locking box 8 is designed with a through opening. The through opening is designed to facilitate the insertion of the connecting post 9 into it.

[0041] The locking box 8 has a cross-shaped horizontal groove 12 and a vertical groove 13 inside. Two symmetrically distributed movable blocks 15 are arranged in the horizontal groove 12. Both movable blocks 15 are T-shaped, with the T-shaped ends extending into the vertical groove 13 and sliding elastically along the longitudinal direction. (See attached image.) Figure 4 As shown, a spring 16 is installed in the longitudinal groove 13. One end of the spring 16 is connected to the T-shaped end of the movable block 15, and the other end of the spring 16 is connected to the end wall of the longitudinal groove 13. When the two movable blocks 15 are pushed apart by a force, the spring 16 is compressed. When the force on the movable blocks 15 is removed, the two movable blocks 15 will slide towards the middle simultaneously under the rebound action of the spring 16.

[0042] The top of the T-shaped end of the movable block 15 is provided with a mounting block 19, and the opposite surfaces of the two mounting blocks 19 are respectively provided with insert blocks 20. The front ends of the opposite inner surfaces of the two movable blocks 15 are respectively provided with notches 17.

[0043] The capacitor assembly 7 has a connecting post 9 at its bottom, and the lower end of the connecting post 9 is inserted into the locking box 8. The tops of the two movable blocks 15 are also provided with pads 18 for placing the connecting post 9. The pads 18 can be regarded as protrusions, and matching notches are pre-cut on the bottom surface of the connecting post 9. When the connecting post 9 is inserted downward, as long as the pads 18 and the notches on the bottom surface of the connecting post 9 are aligned, the insertion position of the connecting post 9 can be considered to be correct.

[0044] The connecting post 9 has slots 10 on both sides that are adapted to the insert block 20. The connecting post 9 is designed as a cylinder. The purpose of designing the connecting post 9 as a cylinder is that the lower end of the connecting post 9 can be quickly inserted between the two mounting blocks 19 of the bottom locking box 8.

[0045] Here, the outer surface of the mounting block 19 is designed to conform to the inner wall of the locking box 8, and the inner surface of the mounting block 19 is designed to conform to the outer wall of the connecting post 9. The mounting block 19 can slide back and forth longitudinally. When the mounting block 19 slides to both sides, its outer surface can be used to fit against the inner wall of the locking box 8, and when the mounting block 19 slides towards the center, its inner surface can be used to fit against the connecting post 9.

[0046] A rotating column 22 and a fixed cylinder 21 are arranged between the two movable blocks 15. A sliding ring 27 is fitted on the column body of the rotating column 22. The sliding ring 27 slides along the length of the column body of the rotating column 22. It should be noted that multiple connecting rods 28 are provided on the rear side of the sliding ring 27. The connecting rods 28 extend rearward and protrude outward from the locking box 8. The ends of the connecting rods 28 are all fixedly installed on the same end block 29. (See attached...) Figure 3As shown, a through hole 14 is provided on the rear side wall of the transverse groove 12 inside the locking box 8 for the connecting rod 28 to slide through. The end block 29 is externally mounted, and by pushing and pulling the end block 29, the internal sliding ring 27 can slide back and forth along the column direction of the rotating column 22.

[0047] The sliding ring 27 abuts against the inner surfaces of the two movable blocks 15. Here, the diameter of the sliding ring 27 is larger than the diameter of the fixed cylinder 21. When the sliding ring 27 contacts the inner plane of the two movable blocks 15, a distance is maintained between the fixed cylinder 21 and the movable blocks 15; while when the sliding ring 27 slides into the notch 17 and is continuously pushed into the depth of the notch 17, the fixed cylinder 21 can abut against the two movable blocks 15.

[0048] When pushed or pulled, the sliding ring 27 can contact the flat surface of the inner surface of the movable block 15 or the inclined surface of the inner surface of the notch 17. When the sliding ring 27 is pushed from back to front, it gradually slides into the notch 17. At this time, the movable blocks 15 on both sides gradually move towards the middle due to the elastic force of the spring 16. Therefore, the inserts 20 on both sides will also move towards the middle at the same time and finally insert into the slot 10 of the connecting post 9. By utilizing the cooperation between the inserts 20 and the slot 10, it can be ensured that the connecting post 9 cannot move vertically at this time, thereby constraining the position of the connecting post 9.

[0049] A spiral groove 23 is provided on the outer surface of the rotating column 22 near its front end. An end post 24 is provided on the front end face of the rotating column 22. The rotating column 22 is rotatably mounted on the front inner wall of the transverse groove 12 via its end post 24. The rotating column 22 and the end post 24 are a single integrated column. The front end of the end post 24 is mounted on the front wall of the transverse groove 12 via a bearing component 32. When the rotating column 22 rotates, the entire column rotates synchronously. A fixed cylinder 21 is fixedly mounted on the rear inner wall of the transverse groove 12. The fixed cylinder 21 is coaxial with the rotating column 22, and the tail end of the rotating column 22 is inserted into the fixed cylinder 21. Here, the fixed cylinder 21 serves to support the rotating column 22.

[0050] It should be noted that the inner wall of the sliding ring 27 is provided with a ball bearing, which is built into the spiral groove 23 and slides along it; the end post 24 is fitted with a bushing 25 that rotates coaxially with it, and a moving contact 26 is installed on the bushing 25.

[0051] As the sliding ring 27 is pushed forward, it gradually slides into the notch 17. Meanwhile, the ball bearings inside the sliding ring 27 slide along the spiral groove 23. Due to the spiral characteristics of the spiral groove 23, the ball bearings inside the sliding ring 27 will cause the end post 24 and the rotating post 22 to rotate as they slide forward. Since the moving contact 26 on the bushing 25 rotates synchronously with the end post 24, the moving contact 26 will also rotate around the end post 24 as the axis as the sliding ring 27 is pushed forward.

[0052] It should be added that, as shown in the attached document Figure 2 Or attached Figure 4 As shown, the notch 17 is designed in a V-shape. The notch 17 can be used to accommodate the pushed-in sliding ring 27 on one hand, and on the other hand, it can be used to accommodate the rotating moving contact 26.

[0053] A stationary contact 11, adapted to the moving contact 26, is provided on the side of the connecting post 9 opposite to the end post 24, as shown in the attached figure. Figure 6 As shown, the bottom surface of the stationary contact 11 has an inverted V-shaped slot. As the moving contact 26 rotates axially, it eventually inserts into the slot at the bottom of the stationary contact 11, forming a stable mating relationship. Electrical wires are embedded in the end post 24 and the connecting post 9. This mating relationship allows for both disconnection and electrical connection between the moving contact 26 and the stationary contact 11, and also constrains the connecting post 9, preventing it from rotating circumferentially around its axis.

[0054] Before inserting the connecting post 9 into the locking box 8, the operator first pulls the sliding ring 27 backward, causing the movable block 15 to separate into two sides. At this time, the spring 16 is compressed, and the moving contact 26 also rotates into the notch 17 on one side. Then, the connecting post 9 is inserted into the locking box 8. After the mating position is adjusted accurately, the sliding ring 27 is pushed forward and enters the notch 17. At this time, on the one hand, the movable blocks 15 on both sides move towards the middle simultaneously and use the insert block 20 to constrain the post 9. On the other hand, the moving contact 26 at the front end rotates synchronously and is locked in the stationary contact 11 on the front side of the connecting post 9. Finally, the mating relationship between the insert block 20 and the slot 10 and the electrical connection relationship between the moving contact 26 and the stationary contact 11 are used to stably restrict the entire connecting post 9 and ensure its fixed position.

[0055] During later maintenance, the capacitor assembly 7 needs to be disassembled. The staff only needs to pull the sliding ring 27 outward, and the plug 20 and the moving contact 26 can be released from the restriction of the connecting post 9. On the one hand, the moving contact 26 and the stationary contact 11 are disconnected, and on the other hand, the connecting post 9 can be quickly pulled out, and the disassembly of the capacitor assembly 7 is finally completed.

[0056] For the capacitor assembly 7 in the middle layer, the capacitor assembly 7 and the locking plate 4 above it can be regarded as a whole. When it is necessary to adjust the height of the pillar capacitor, it is necessary to increase or decrease the number of layers of capacitor assembly 7. Here, it is only necessary to appropriately increase or decrease the number of capacitor assembly 7 and locking plate 4 installed in the middle layer.

[0057] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
