Description

A type of parallel capacitor device Technical Field

[0001] This utility model relates to the field of capacitor device technology, specifically a combined parallel capacitor device. Background Technology

[0002] Parallel capacitor banks are important devices used in power systems, primarily for improving power factor, reducing line energy loss, and improving voltage quality. They typically consist of multiple capacitor units connected in parallel to form a large capacitance.

[0003] When using capacitor devices, multiple sets need to be connected in parallel. However, traditional capacitor devices are usually mounted on a base for fixing, which results in a large size of the capacitor device. This makes it difficult to install the capacitor device inside the electrical cabinet. Furthermore, when using multiple connecting wires, if the connecting wires are tangled or pulled, they are prone to bending and damage. Therefore, we propose a combined parallel capacitor device. Summary of the Invention

[0004] The purpose of this invention is to provide a combined parallel capacitor device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a combined parallel capacitor device, including a housing, a bottom fixing ring fixedly installed at the bottom of the housing, a mounting base fixedly installed at the top of the housing, a plurality of connectors provided on the mounting base, and a detachable mounting mechanism that engages with the bottom fixing ring at the bottom of the housing;

[0006] The installation mechanism includes a snap ring, a connecting block, a locking screw, a locking nut, a mounting plate, and a locking groove. The snap ring is sleeved on the outside of the bottom fixing ring. The mounting plate is fixedly installed on the outside of the snap ring. The mounting plate has a through locking groove. The connecting blocks are fixedly connected to both sides of the snap ring. The locking screw is inserted into the connecting block. The locking nut is threaded onto the outside of the locking screw.

[0007] The top of the housing and outside the mounting base is provided with a protective mechanism to protect the connector, and the two sides of the housing are provided with guide and limiting mechanisms to prevent the connecting wire from being bent and damaged.

[0008] Furthermore, the protective mechanism includes a protective shell, a clearance groove, a locking seat, a mounting groove, a rotating shaft, and a locking piece. The protective shell has multiple clearance grooves, and both ends of the protective shell are fixedly connected to locking seats. An elliptical mounting groove is formed through the locking seat. A rotating shaft is fixedly installed on the top of the shell, and a locking piece that matches the mounting groove is rotatably connected to the top of the rotating shaft.

[0009] Furthermore, the guide limiting mechanism includes a top limiting ring, a positioning groove, a connecting shaft, a connecting piece, and a guide block. The top limiting ring is fixedly installed on the top of the housing. Two sets of positioning grooves are provided on the top limiting ring. The connecting shaft is internally connected to a connecting piece at one end, and a guide block with one side arc-shaped is fixedly connected at the other end.

[0010] Furthermore, a cushioning pad made of rubber material is laid on the side of the guide block away from the connecting shaft.

[0011] Furthermore, the locking groove is configured as an elongated shape.

[0012] Furthermore, the outer surface of the protective shell is coated with an insulating coating, and the bending arc of the guide block is 45°.

[0013] Compared with the prior art, the present invention has the following advantages: the bottom fixing ring of the present invention can be installed in conjunction with the installation mechanism, and the installation mechanism and the bottom fixing ring can be detached from each other, thereby reducing the size of the housing and making it easier to put the housing into the electrical cabinet.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please refer to Figures 1-4. This utility model provides a technical solution: a combined parallel capacitor device, including a housing 1, a bottom fixing ring 2 fixedly installed at the bottom of the housing 1, a mounting base 4 fixedly installed at the top of the housing 1, multiple sets of connectors 5 provided on the mounting base 4, a mounting mechanism 3 that engages with the bottom fixing ring 2 at the bottom of the housing 1, a protection mechanism 6 for protecting the connectors 5 at the top of the housing 1 and outside the mounting base 4, and guide and limiting mechanisms 7 for preventing bending and damage to the connecting wires on both sides of the housing 1.

[0021] The bottom fixing ring 2 can be installed in conjunction with the mounting mechanism 3, and the mounting mechanism 3 and the bottom fixing ring 2 can be detached from each other, thereby reducing the size of the housing and making it easier to put the housing into the electrical cabinet. The protective mechanism 6 can be set on the outside of the connector 5, thereby protecting the connector 5 after it is connected to the connecting wire and preventing external parts from affecting the connector. The connecting wire connected to the connector 5 can be protected by the guide limiting mechanism 7 to prevent the wire harness from falling or bending due to its long size.

[0022] Please refer to Figures 1 and 2. The mounting mechanism 3 includes a snap ring 8, a connecting block 9, a locking screw 10, a locking nut 11, a mounting plate 12, and a locking groove 13. The snap ring 8 is sleeved on the outside of the bottom fixing ring 2. The mounting plate 12 is fixedly installed on the outside of the snap ring 8. The locking groove 13 is formed through the mounting plate 12. The locking groove 13 is elongated. The connecting blocks 9 are fixedly connected to both sides of the snap ring 8. The locking screw 10 is inserted into the connecting block 9. The locking nut 11 is threaded onto the outside of the locking screw 10.

[0023] During the installation of the housing 1, one set of mounting plates 12 is installed inside the external electrical cabinet. Then, the locking nut 11 is loosened so that the two sets of retaining rings 8 are separated from each other. Then, the bottom fixing ring 2 at the bottom of the housing 1 is connected to the retaining ring 8. Then, the locking nut 11 is rotated so that it rotates along the locking screw 10. In this way, the two sets of retaining rings 8 and the bottom fixing ring 2 can be locked to each other, thus completing the fixed connection of the housing 1.

[0024] Please refer to Figures 1 and 2. The protective mechanism 6 includes a protective shell 14, a clearance groove 15, a locking seat 16, a mounting groove 17, a rotating shaft 18, and a locking piece 19. The protective shell 14 has multiple clearance grooves 15. Both ends of the protective shell 14 are fixedly connected to the locking seat 16. An elliptical mounting groove 17 is provided through the locking seat 16. The rotating shaft 18 is fixedly installed on the top of the shell 1. The top of the rotating shaft 18 is rotatably connected to a locking piece 19 that matches the mounting groove 17.

[0025] After the connecting wire and connector 5 are connected, the mounting groove 17 corresponds to the locking piece 19. The protective shell 14 can then pass through the locking piece 19 and contact the top of the shell 1. The locking piece 19 is then rotated along the pivot 18, so that the locking piece 19 can be attached to the top of the locking seat 16, thereby fixing the protective shell 14.

[0026] Please refer to Figures 1, 2, and 4. The guide limiting mechanism 7 includes a top limiting ring 20, a positioning groove 21, a connecting shaft 22, a connecting piece 23, and a guide block 24. The top limiting ring 20 is fixedly installed on the top of the housing 1. Two sets of positioning grooves 21 are provided on the top limiting ring 20. The connecting piece 23 is fixedly connected to one end of the connecting shaft 22. The other end of the connecting shaft 22 is fixedly connected to a guide block 24 with one side arc-shaped. A buffer pad made of rubber material is laid on the side of the guide block 24 away from the connecting shaft 22. The thickness of the buffer pad is set to 3mm.

[0027] When the guide block 24 needs to be installed, the connecting shaft 22 is passed through the inside of the positioning groove 21. This allows the guide block 24 and the connecting shaft 22 to be fixed to the outside of the housing 1. The guide block 24, which has an arc shape on one side, can guide the connecting line and prevent the connecting line from bending or being damaged.

[0028] Please refer to Figures 1-3. The protective shell 14 is coated with an insulating coating on the outside, and the guide block 24 has a bending arc of 45°. The insulating layer coated on the outside of the protective shell 14 can provide insulation protection for the internal components, while the arc setting of the guide block 24 can adapt to the bending angle of the cable.

[0029] In use, firstly, the bottom fixing ring 2 can be installed in conjunction with the mounting mechanism 3, and the mounting mechanism 3 and the bottom fixing ring 2 can be detached from each other, thereby reducing the size of the housing and facilitating its placement inside the electrical cabinet. The protective mechanism 6 can be located outside the connector 5, protecting it from external components after connection to the connecting wire. The connecting wire connected to the connector 5 can be protected by the guide and limiting mechanism 7 to prevent it from falling or bending due to its length. During housing 1 installation, one set of mounting plates 12 is installed inside the external electrical cabinet. Then, the locking nut 11 is loosened, causing the two sets of retaining rings 8 to move away from each other. Next, the bottom fixing ring 2 at the bottom of housing 1 is connected to the retaining ring 8, and then the locking nut 11 is rotated to... It rotates along the locking screw 10, so that the two sets of snap rings 8 and the bottom fixing ring 2 can be locked together, thus completing the fixed connection of the housing 1. After the connecting wire and the connector 5 are connected, the mounting groove 17 corresponds to the locking piece 19. The protective shell 14 can then pass through the locking piece 19 and contact the top of the housing 1. Then, the locking piece 19 is rotated along the rotating shaft 18, so that the locking piece 19 can overlap the top of the locking seat 16, thus completing the fixation of the protective shell 14. When it is necessary to install the guide block 24, the connecting shaft 22 is passed through the inside of the positioning groove 21, so that the guide block 24 and the connecting shaft 22 can be fixed to the outside of the housing 1. In this way, the guide block 24 with one side arc-shaped can be used to guide the connecting wire and prevent the connecting wire from bending and being damaged.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
