Abstract
Description
Technical Field
[0001] This utility model relates to the field of capacitor technology, specifically to a limiting mechanism and a parallel capacitor having the limiting mechanism. Background Technology
[0002] Parallel capacitors (formerly known as phase-shifting capacitors) are reactive power compensation devices primarily used to compensate for the reactive power of inductive loads in power systems. Parallel capacitors play a crucial role in power systems, improving the power factor (the ratio of actual power to apparent power), thus making the power system operate more efficiently. Furthermore, parallel capacitors improve voltage quality by providing additional reactive power support, helping to maintain voltage stability in the power grid.
[0003] Currently, the casing of existing parallel capacitors is only installed and fixed with bolts. During use, the bolts are prone to loosening, which means that the casing cannot effectively protect the internal electronic components, thus affecting the normal use of the parallel capacitor. Utility Model Content

[0018] In one embodiment disclosed in this application, a pair of limiting plates are symmetrically arranged around the center of the top surface of the base, and are respectively located on both sides of the slot.
[0019] In one embodiment disclosed in this application, the third limiting member includes a support block fixedly disposed on the top surface of the base and a screw rod rotatably passing through the support block. The end of the screw rod away from the support block is rotatably connected to the middle stop portion through a bearing.

[0039] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0040] See Figures 1-4 As shown, on one hand, this utility model provides a limiting mechanism connected to the housing 100 of a parallel capacitor. This limiting mechanism includes:
[0041] Base 200;
[0042] The first limiting member is used to prevent the outer casing 100 from loosening along its length.
[0043] The second limiting member is used to prevent the outer casing 100 from loosening along its width direction; and
[0044] The third limiting component is used to prevent the outer casing 100 from loosening along its height direction;
[0045] The first limiting member is located between the outer shell 100 and the base 200, the second limiting member is located on the base 200 and at the end of the outer shell 100 in the length direction, and the third limiting member is located on the base 200 and is connected one-to-one with the second limiting member.
[0046] By setting the first to third limiting members to limit the housing 100 in multiple directions in length, width and height to prevent it from loosening, the electronic components inside the housing 100 can be effectively protected, thereby ensuring the normal use of the parallel capacitor.
[0047] The first limiting member includes an insert 110 located at the bottom of the housing 100 and a slot 210 located on the top surface of the base 200 and corresponding to the insert 110. The insert 110 extends along the width direction of the housing 100, and the insert 110 and the slot 210 are connected to form the first limiting structure. The housing 100 can be fixed to the top surface of the base 200 by the insertion of the insert 110 and the slot 210, and the base 200 supports the housing 100. When the housing 100 is subjected to an external force in its length direction, the cooperation between the insert 110 and the slot 210 can block the housing 100 so that it is restricted in the length direction and cannot move, thereby preventing the housing 100 from loosening along its length direction.
[0048] Multiple inserts 110 are arranged at equal intervals along the length of the housing 100. Each insert 110 is inserted into its corresponding slot 210, which can enhance the stopping effect of the housing 100 along its length.
[0049] In this embodiment, there are three inserts 110 arranged at equal intervals along the length of the outer casing 100.
[0050] See Figure 3As shown, the second limiting member includes a limiting plate 220 fixedly disposed on the top surface of the base 200. The limiting plate 220 has a central stop 221 and a pair of side stops 222. The pair of side stops 222 are respectively vertically connected to both ends of the central stop 221 to form a U-shaped second limiting structure. The central stop 221 abuts against the end side surface of the outer shell 100 in the length direction, and the side stops 222 abut against the end side surface of the outer shell 100 in the width direction. Through the pair of side stops 222, the outer shell 100 can be blocked so that it is restricted in the width direction and cannot move, thereby preventing the outer shell 100 from loosening along its width direction.
[0051] To enhance the stopping effect of the outer casing 100 along its width, a pair of limiting plates 220 are symmetrically arranged at the center of the top surface of the base 200, respectively located on both sides of the slot 210. In this way, the pair of limiting plates 220 can respectively stop the four corners of the outer casing 100.
[0052] The third limiting component includes a support block 230 fixedly mounted on the top surface of the base 200 and a screw 240 rotatably passing through the support block 230. The end of the screw 240 away from the support block 230 is rotatably connected to the middle stop 221 via a bearing. A locking block 250 is threaded onto the screw 240, and the locking block 250 slides through the middle stop 221. Rotating the screw 240 allows the locking block 250 to engage with a slot on the side of the outer casing 100 along its length, thus forming the third limiting structure. The rotating screw 240 pushes the locking block 250 to slide on the middle stop 221 and extends into the slot on the side of the outer casing 100 along its length, achieving a locking connection. This prevents the outer casing 100 from moving in the height direction, thereby preventing it from loosening along its height.
[0053] To enhance the stopping effect of the outer casing 100 along its height direction, the locking block 250 has a U-shaped structure with a pair of horizontal tongue plates 251. The screw 240 is located between the pair of tongue plates 251, and a pair of slots are provided on the side of the outer casing 100 along its length direction. Under the push of the screw 240, the tongue plates 251 slide through the middle stop 221 and can be inserted into the slots one by one.
[0054] On the other hand, this utility model provides a parallel capacitor with the limiting mechanism described above. When the parallel capacitor is in use, the first to third limiting members can limit the outer casing 100 in multiple directions in the length, width and height directions, respectively, which can prevent the outer casing 100 from loosening and effectively protect the internal electronic components, thus helping to extend the service life of the parallel capacitor.
[0055] The above embodiments are merely preferred embodiments of this utility model and are not intended to limit the technical solutions of this utility model. Any technical solution that can be implemented based on the above embodiments without creative effort should be considered to fall within the scope of protection of this utility model patent.
