Description

Technical Field

[0001] The invention relates to the technical field of electrical engineering capacitor clamping devices, in particular to an electrical engineering capacitor clamping device. Background Art

[0002] Capacitors are commonly used electronic devices in the fields of electrical and communication engineering. They are a type of reactive compensation device. Their functions include phase shifting, coupling, voltage reduction, filtering, etc. In ultra-high voltage systems, there are a large number of harmonics. When harmonic current flows through the capacitor, the internal electrodes and insulating materials of the capacitor are affected by the distorted electric field generated by the harmonics and vibrate, causing the circuit board to vibrate and produce noise, which is capacitor howling. In order to avoid or reduce the howling noise, a clamp is generally set on the outside of the capacitor to fix it in order to reduce the vibration of the capacitor.

[0003] Capacitors can be divided into shunt capacitors, series capacitors, coupling capacitors, circuit breaker capacitors, electric heating capacitors, pulse capacitors, DC and filter capacitors, and standard capacitors according to their uses. Common shapes of capacitors include cylindrical and cubic shapes.

[0004] Scheme CN221160022U discloses a capacitor clamping device for communication engineering, which achieves the clamping of the capacitor by cooperating with a clamping shell, a rubber pad, a groove, a telescopic rod, a spring and an arc-shaped mounting plate, and by arranging vertical grooves, through holes, a main ventilation pipe, a side ventilation pipe and a filter plate, the heat at the clamped part of the capacitor can be discharged to the outside of the rubber pad, thereby avoiding heat accumulation in the capacitor and affecting its service life.

[0005] However, the clamping shell and rubber pad of this solution are arc-shaped, and the clamping shell structure is fixed, so it is only suitable for clamping cylindrical capacitors of matching sizes. It cannot achieve a stable clamping effect for cubic capacitors, and the clamping effect will also deteriorate for larger or smaller capacitors. In addition, when in use, although the rubber pad is provided with a through hole, the rubber pad wraps the side wall of the cylindrical capacitor with the entire surface, and the side wall of the capacitor cannot be in open contact with the air, resulting in poor heat dissipation effect.

[0010] The push rod group includes a plurality of push rods which are fixed as a whole and arranged longitudinally. A rubber head is provided at the front end of the push rod, and the rubber head touches the capacitor.

[0017] As an improvement, the diameter of the screw is larger than that of the push rod.

[0018] As an improvement, mounting holes are provided at the four corners of the base plate.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] This embodiment combines the attached Figures 1 to 6 , a capacitor clamping device for electrical engineering is described in detail.

[0036] The present embodiment is an electrical engineering capacitor clamping device, comprising a bottom plate 1, a left-right symmetrical vertical plate is provided on the top of the bottom plate 1, the vertical plate comprises an inner vertical plate 2 and an outer vertical plate 3, the inner vertical plate 2 and the outer vertical plate 3 are both convex outwards;

[0037] It also includes a push rod structure, which is distributed along the circumference of the convex surface of the vertical plate and is gathered inwardly. The push rod structure includes a screw rod 4 and a push rod group 5. The screw rod 4 is rotated to penetrate the outer vertical plate 3 through a thread, and the push rod group 5 is slid into the inner vertical plate 2. The screw rod 4 can push the middle part of the push rod group 5 from the gap 10 between the inner vertical plate 2 and the outer vertical plate 3;

[0038] The push rod group 5 includes a plurality of push rods that are fixed as a whole and arranged longitudinally. A rubber head 6 is provided at the front end of the push rod, and the rubber head 6 touches the capacitor.

[0039] In the specific implementation, the capacitor is inserted between the two inner vertical plates 2. If it is a clamped cylindrical capacitor, the clamping form of the top rod structure is as follows: Figure 5 If it is a clamped cube capacitor, the clamping form of the ejector rod structure is as follows: Figure 6Then, each screw rod 4 is rotated successively to push the corresponding push rod group 5, so that the rubber head 6 of each push rod group 5 touches the outer wall of the capacitor, thereby achieving the effect of clamping the capacitor from both sides. The rubber head 6 has an insulating effect, and each push rod is in point contact with the capacitor. The push rod forms a gap between the capacitor and the inner vertical plate 2, which facilitates the heat dissipation of the capacitor to the surrounding area.

[0040] The vertical plate is a longitudinally cut half octagonal tube and the convex end of the vertical plate is a pointed end. The four side planes of the vertical plate are provided with a push rod structure. The screw rod 4 and the push rod are perpendicular to the side planes of the inner vertical plate 2 and the outer vertical plate 3.

[0041] In the specific implementation, the vertical plate is made into the shape of a longitudinally cut half octagonal tube, and the convex end of the vertical plate is a pointed end, which is convenient for setting the orientation of the top rod structure and is perpendicular to the side planes of the inner vertical plate 2 and the outer vertical plate 3. It is suitable for clamping cylindrical capacitors or cubic capacitors, and the inner angle of the side plane is further conducive to heat dissipation and ventilation.

[0042] Each side plane of the inner vertical plate 2 is provided with two spaced-apart parallel push rod groups 5 .

[0043] In a specific implementation, each side plane is provided with two spaced-apart parallel push rod groups 5 to make the clamping effect of the capacitor more stable.

[0044] The top rods of adjacent top rod groups 5 are staggered in the longitudinal direction.

[0045] In specific implementation, when the capacitor is small, the top rod group 5 needs to extend longer into the inner side of the inner vertical plate 2, and the top rods of adjacent top rod groups 5 are arranged to be staggered along the longitudinal direction, so that adjacent top rod groups 5 at an angle can cross smoothly without conflict, and do not affect the clamping of the small capacitor.

[0046] The outer end of the screw rod 4 is provided with an anti-slip head 7 for manual rotation.

[0047] In a specific implementation, the anti-slip head 7 makes it more convenient to operate the rotating screw rod 4 by hand.

[0048] A circular area consisting of a plurality of ventilation holes 8 is provided in the middle of the bottom plate 1 , and the circular area of ​​ventilation holes 8 is located between the two inner vertical plates 2 .

[0049] In a specific implementation, the circular area formed by the ventilation holes 8 further facilitates the ventilation and heat dissipation of the capacitor.

[0050] The contact surfaces of the screw rod 4 and the push rod assembly 5 are both smooth planes.

[0051] In specific implementation, the screw rod 4 is not directly connected to the push rod assembly 5. When vibration occurs, the smooth plane contacts make it difficult to transmit circumferential power, which significantly reduces the possibility of the screw rod 4 loosening.

[0052] The diameter of the screw rod 4 is larger than that of the top rod.

[0053] In a specific implementation, the diameter of the screw rod 4 is larger than that of the push rod, so that the force effect of the push rod is better during pushing.

[0054] The base plate 1 is provided with mounting holes 9 at four corners.

[0055] In a specific implementation, the mounting hole 9 is used to mount the device in the equipment.

[0056] When in use, the device is installed near the capacitor, and the capacitor is placed between the two inner vertical plates 2. Then, the screw rods 4 are rotated to adjust the top rod group 5, and the capacitor is clamped from both sides to achieve the effect of clamping and fixing the capacitor. The device can be used to clamp and fix cylindrical capacitors and cubic capacitors, and is convenient for ventilation and heat dissipation.

[0057] The present invention and its embodiments are described above, and such description is not restrictive, and the actual protection scope is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the protection scope of the claims.
