The self-healing capacitor for reactive power automatic compensation combines an automatic adjustment function and a self-healing characteristic, and is an important device for improving voltage stability and power factor in the power system.

[0003] When the existing self-healing capacitors for reactive power automatic compensation are in use, they are usually used in series or in parallel. Therefore, the connection heads of the self-healing capacitors for reactive power automatic compensation may be connected to the lines on both sides. When the connection heads of the self-healing capacitors for reactive power automatic compensation are protected by a protective cover, in order to connect the lines on both sides at the same time and for the convenience of wiring, the line openings on both sides of the protective cover are too large, which is easily affected by the external environment, such as vibration causing the lines to become loose, and the covering of water droplets or dust, etc., thus affecting its service life.

[0004] Therefore, it is necessary to design a self-healing capacitor for reactive power automatic compensation to solve the above problems. Content of the Utility Model

The top ends of the first springs are fixedly connected to the top of the inner cavity of the protection cover. The top ends of the two plug posts penetrate through the top of the protection cover, and a limiting piece is fixedly connected to the common top end of the two plug posts.

[0008] Preferably, the sizes of the two slots match the sizes of the two plug boards, and the depths of the two slots are greater than the radius lengths of the semi-circular openings on the two plug boards.

[0009] Preferably, the shape of the pull block is T-shaped. The T-shaped bottoms of the two pull blocks are respectively slidably arranged inside the two connecting grooves, and the bottoms of the T-shaped tops of the two pull blocks are in contact with the top of the capacitor body.

[0017] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.

[0018] Obviously, many specific details are set forth in the following description in order to fully understand the present utility model. However, the present utility model may also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the limitations of the specific embodiments disclosed in the following specification.

[0019] Please refer to Figures 1-3, the utility model provides a self-healing capacitor for reactive power automatic compensation, which includes a capacitor body 1. A wiring terminal 10 is arranged at the top of the capacitor body 1. A protective cover 2 is movably clamped outside the wiring terminal 10. Elastic plug plates 5 are arranged on both sides of the protective cover 2. Three semi-circular openings are arranged on the outer surface of the plug plate 5. Plugging blocks 14 are fixedly connected to both sides of the bottom of the protective cover 2. Two symmetrical connecting grooves 12 are arranged at the top of the capacitor body 1. Second springs 11 are fixedly connected to one side of the inner cavities of the two connecting grooves 12. Pulling blocks 3 are fixedly connected to one ends of the two second springs 11. Plugging columns 13 are fixedly connected to one side of the bottom ends of the two pulling blocks 3. One jack is arranged on one side of each of the two plugging blocks 14 corresponding to the two plugging columns 13. One ends of the two plugging columns 13 are slidably inserted into the two jacks. Baffles 8 are fixedly connected to one side of each of the two plug plates 5. Two symmetrical slots 15 are arranged at the top of the capacitor body 1. A plurality of water permeable holes 9 are arranged on the outer surfaces of both sides of the capacitor body 1 corresponding to the two slots 15. The two plug plates 5 are slidably inserted into the two slots 15. When installing the circuit, the two pulling blocks 3 can be pulled on both sides of the capacitor body 1, and the two plugging columns 13 are respectively slid out of the two jacks, so as to remove the protective cover 2 and the components on the protective cover 2 from the top of the wiring terminal 10, thus facilitating wiring. After wiring is completed, the two pulling blocks 3 are continuously pulled, so that by using the elastic force of the two second springs 11, when the protective cover 2 is clamped to the top of the wiring terminal 10, the protective cover 2 can be fixed by the insertion of the two plugging columns 13 and the two plugging blocks 14. At the same time of fixing, the semi-circular openings of the two plug plates 5 will come into contact with the circuit first. At this time, the circuit will push the plug plate 5 to elastically contract, so as to clamp the connecting circuit by using the semi-circular openings on the plug plate 5, ensuring the stable connection of the circuit and improving the connection tightness of the protective cover 2. Since wiring can be carried out on both sides of the protective cover 2, if wiring is carried out on both sides of the wiring terminal 10, the two plug plates 5 will be used for wire clamping work. When wiring is not carried out on one side, at this time, the plug plate 5 on this side will be inserted into the corresponding slot 15 under the elastic force, so as to block the semi-circular opening and block the opening between the exposed limiting piece 4 and the protective cover 2 through the plug plate 5, thus realizing the closing effect, ensuring the circuit protection function of the overall protective cover 2, improving the use safety of the overall device, and thus improving the service life of the capacitor body 1.

[0020] In the above description, in order to make the plug board 5 elastic, symmetric plug posts 6 are fixedly connected to both ends of the top of the two plug boards 5. The outer surfaces of the two plug posts 6 are sleeved with first springs 7. The top ends of the first springs 7 are fixedly connected to the top of the inner cavity of the protective cover 2. The top ends of the two plug posts 6 penetrate through the top of the protective cover 2. A limiting piece 4 is fixedly connected to the top ends of the two plug posts 6 together. Through the sliding of the plug posts 6 on the top of the protective cover 2 and the elastic contraction of the first springs 7, the two plug boards 5 can have the performance of elastic sliding.

[0021] In order to make the slots 15 have good sealing performance when slidingly inserted with the plug boards 5, the sizes of the two slots 15 match the sizes of the two plug boards 5, and the depths of the two slots 15 are greater than the radius lengths of the semi-circular openings on the two plug boards 5.

[0022] In order to facilitate pulling the two pull blocks 3 and thus facilitate the insertion of the protective cover 2, the pull blocks 3 are in a T shape. The T-shaped bottoms of the two pull blocks 3 are slidably arranged inside the two connecting grooves 12 respectively, and the bottoms of the T-shaped tops of the two pull blocks 3 are in contact with the top of the capacitor body 1.

[0023] Furthermore, in order to facilitate the discharge of water stains generated inside the slots 15, the heights of one ends of the multiple water-permeable holes 9 inside the slots 15 are all higher than the heights of the ends outside the capacitor body 1. The baffle 8 is in an L shape, and the horizontal end of the baffle 8 is located between the corresponding limiting piece 4 and the top of the protective cover 2.

However, the present invention is not limited to the specific details in the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solutions of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0025] In addition, it should be noted that, among the various specific technical features described in the above specific embodiments, they can be combined in any appropriate way without conflict.
