Abstract
Description
Technical Field

[0002] Power capacitors are capacitors used in power systems and electrical equipment. Any two metal conductors separated by an insulating medium constitute a capacitor. The capacitance of a capacitor is determined by its geometric dimensions and the characteristics of the insulating medium between the two plates.

[0003] Our country is located where several plates, including the Pacific Plate, the Eurasian Plate, and the Indian Plate, meet. There are at least 495 earthquake fault zones. The frequency of earthquake activities is high, the intensity is high, the epicenter is shallow, and the distribution is wide. China is a country prone to serious earthquake disasters.

In severe cases, sparks may be generated and fires may occur. Utility Model Content

[0023] The present application embodiment discloses a seismic-resistant power capacitor. Figure 1-Figure 4The seismic-resistant power capacitor includes a capacitor body 1, a base 2 and a shock absorbing mechanism 3. A fixing base 11 is connected to the bottom of the capacitor body 1. The fixing base 11 is in the shape of an open rectangular box. A slider 111 is connected to the fixing base 11. The slider 111 is respectively provided at the four corners of the bottom surface of the fixing base 11. A guide rail 21 is connected to the base 2. The guide rail 21 is arranged along the length direction of the base 2. The guide rail 21 is symmetrically provided on both sides of the midline of the length direction of the base 2. The slider 111 is slidably arranged on the guide rail 21, wherein the slider 111 is a damping slider 111. Through the principle of magnetic damping, the lateral movement generated by the external force acting on the capacitor body 1 is hindered, and the vibration is buffered.
[0024] The shock absorbing mechanism 3 includes a first hinge seat 31, a second hinge seat 32, a shock absorbing spring 33 and a shock absorbing telescopic rod 34. The first hinge seat 31 is connected to the fixed seat 11. Two first hinge seats 31 are respectively provided on opposite sides of the fixed seat 11. The two first hinge seats 31 are symmetrically arranged about the midline of the surface on which they are located. The second hinge seat 32 is connected to the base 2. Two second hinge seats 32 are respectively provided on opposite sides of the base 2 corresponding to the first hinge seats 31. The two ends of the shock absorbing telescopic rod 34 are respectively hinged on the first hinge seat 31 and the second hinge seat 32. The two ends of the shock absorbing telescopic rod 34 are respectively hinged on the first hinge seat 31 and the second hinge seat 32. Both ends are connected with spring seats, and the shock-absorbing spring 33 is sleeved on the telescopic rod. Both ends of the shock-absorbing spring 33 are in contact with the spring seats. Under the sliding limit action of the slider 111 and the guide rail 21, the vibration generated by the external force acting on the capacitor body 1 will be converted into lateral movement of the capacitor body 1 on the guide rail 21. When the capacitor body 1 is laterally displaced on the guide rail 21, the shock-absorbing spring 33 on one side of the moving direction will be compressed and the shock-absorbing spring 33 on the other side will be stretched. The shock-absorbing springs 33 on both sides respectively generate compressed elastic force and stretched elastic force, thereby buffering the vibration.
[0025] A stabilizing component 4 for improving the stability of the waist of the capacitor body 1 is also provided between the capacitor body 1 and the base 2. The stabilizing component 4 includes a first connecting seat 41, a second connecting seat 42 and a shock-absorbing rope 43. A U-shaped frame 112 is connected to the fixing seat 11. The U-shaped frame 112 is hooped from top to bottom on the outside of the capacitor body 1. A through slot for the terminal of the capacitor body 1 to pass through is provided on the U-shaped frame 112. The first connecting seat 41 is connected to the U-shaped frame 112. The first connecting seat 41 is provided with one on each of the two opposite sides of the U-shaped frame 112. The first connecting seat 41 is located at the waist position of the capacitor body 1, the second connecting seat 42 is connected to the base 2, and the second connecting seat 42 is respectively provided with one on the opposite sides of the base 2 corresponding to the first connecting seat 41. The two ends of the shock-absorbing rope 43 are respectively connected to the first connecting seat 41 and the second connecting seat 42. The waist position of the capacitor body 1 is connected to the fixed base 2 by using the shock-absorbing rope 43, and the elasticity of the steel wire rope in the shock-absorbing rope 43 is used to absorb vibration energy, thereby reducing the transmission and influence of vibration and improving the stability of the capacitor body 1.
[0026] The shock-absorbing telescopic rod 34 includes a mounting cylinder 341, a sealing cover 342, a piston rod 343 and a piston block 344. The mounting cylinder 341 is filled with damping oil. The sealing cover 342 is connected to the cylinder mouth of the mounting cylinder 341. The piston rod 343 passes through the sealing cover 342 and is arranged in the mounting cylinder 341. The axis of the piston rod 343 is colinear with the axis of the mounting cylinder 341. The piston block 344 is connected to the end of the piston rod 343 located in the mounting cylinder 341. The side wall of the piston block 344 slides and fits the inner wall of the mounting cylinder 341. The piston block 344 is provided with a through hole for the damping oil to pass through. A plurality of through holes are evenly arranged along the circumference of the piston block 344. When the shock-absorbing telescopic rod 34 is compressed or stretched, the piston block 344 moves in the mounting cylinder 341. The damping oil flows from one side of the piston block 344 to the other side through the through hole. The resistance generated by the damping oil during the flow process will further buffer the vibration.
[0027] The fixing base 11 is provided with heat dissipation holes 113, which penetrate the inner wall and the outer wall of the fixing base 11. A plurality of heat dissipation holes 113 are evenly arranged on the side wall of the fixing base 11. Since the fixing base 11 is wrapped around the outside of the capacitor body 1, the heat dissipation holes 113 are utilized to ensure the heat dissipation of the capacitor body 1 and prevent the bottom temperature from being too high.
[0028] A counterweight 114 is connected to the fixing seat 11 . The counterweight 114 is located at the center of the bottom of the fixing seat 11 . The counterweight 114 lowers the center of gravity of the capacitor body 1 as a whole, so as to improve the stability of the capacitor body 1 .
[0029] Finally, it should be noted that the above is only the preferred implementation of the utility model, and the protection scope of the utility model is not limited to the above embodiments. All technical solutions under the idea of the utility model belong to the protection scope of the utility model. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the utility model should also be regarded as the protection scope of the utility model.
