[0002] High-voltage capacitors are important electrical components with low loss and light weight. They play a key role in power systems. They can adapt to various voltage levels by connecting capacitor elements in series or in parallel.
[0003] Large-capacity high-voltage capacitors are larger in size because they need to provide more current compensation capabilities. They need to be hoisted and placed on a trailer. During the hoisting process, the outer wall of the existing device will collide with the capacitor placed in the trailer, causing the outer wall to deform, which will affect the sealing effect of the capacitor and cause internal electrolyte leakage, significantly shortening the service life of the capacitor. In addition, during use, the capacitor may explode due to a malfunction, and fragments will spread to the surrounding area, causing injuries to nearby people. Utility Model Content

At this time, the entire capacitor is also completely placed on the installation surface. Multiple guard plates are close to the outer wall of the shell, which can prevent the explosion of the capacitor when it fails and cause the fragments to spread around, avoid personal injury, and have higher safety.
[0018] 2. Multiple heat dissipation slots are respectively opened inside the multiple guard plates, and multiple grooves are opened on the outer walls of the shell.

[0028] When the capacitor is hoisted, multiple telescopic plates 9 and the guard plates 11 connected thereto are all in an outwardly extended state, which can prevent the two capacitors from colliding with each other and causing deformation of the outer wall of the capacitor, and protect the outer wall of the capacitor. When installing the capacitor, the capacitor to be installed is hoisted to the installation position, and the lower capacitor and the pressure block 4 are squeezed and moved upward by the installation surface. Multiple linkage plates 7 and the linkage rods 8 connected to the outer walls on both sides move up synchronously with the pressure block 4. During this process, multiple springs 6 are in a compressed state. When the linkage rod 8 moves upward, it moves along the linkage groove 10 opened on the inner wall of the telescopic plate 9, so that the telescopic plate 9 drives the guard plate 11 to shrink until the guard plate 11 is close to the outer wall of the shell 1, and at this time the entire capacitor is also completely placed on the installation surface. Multiple guard plates 11 are close to the outer wall of the shell 1, which can prevent the explosion of the capacitor when it fails and cause the fragments to spread around, avoid personal injury, and have higher safety.
[0029] Multiple guard plates 11 are located outside the shell 1, and multiple heat dissipation slots 12 are opened inside the multiple guard plates 11, and the number of heat dissipation slots 12 is multiple. The outer wall of the shell 1 is opened with grooves 13, and the number of grooves 13 is multiple.
[0030] A plurality of heat dissipation grooves 12 are respectively provided inside the plurality of guard plates 11, and a plurality of grooves 13 are provided on the outer walls of the outer shell 1. The slide plate 11 is located outside the groove 13. When the plurality of guard plates 11 are close to the outer wall of the outer shell 1, the heat generated by the entire capacitor during operation is dissipated outward through the plurality of grooves 13 and the plurality of heat dissipation grooves 12 in sequence, thereby improving the heat dissipation performance of the entire capacitor.

A core 16 is provided inside the shell 1, and a pin 17 is connected to the top of the core 16. There are two pins 17, and both pins 17 pass through the top of the shell 1.
[0032] Working principle: When the capacitor is being hoisted, multiple telescopic plates 9 and the guard plates 11 connected thereto are all in an outwardly extended state, which can prevent the two capacitors from colliding with each other and causing deformation of the outer wall of the capacitor, and protect the outer wall of the capacitor. When installing the capacitor, the capacitor to be installed is hoisted to the installation position, and the capacitor below, the pressure block 4 is squeezed and moved upward by the installation surface. Multiple linkage plates 7 and the linkage rods 8 connected to the outer walls on both sides move upward synchronously with the pressure block 4. During this process, multiple springs 6 are in a compressed state. When the linkage rod 8 moves upward, it moves along the linkage groove 10 opened on the inner wall of the telescopic plate 9, so that the telescopic plate 9 drives the guard plate 4 to move upward. The plate 11 shrinks until the guard plate 11 is close to the outer wall of the shell 1, and at this time the entire capacitor is also completely placed on the mounting surface. Multiple guard plates 11 are close to the outer wall of the shell 1, which can prevent the explosion of the capacitor when it fails and cause the fragments to spread around, avoid personal injury, and provide higher safety. Multiple heat dissipation grooves 12 are respectively opened inside the multiple guard plates 11, and multiple grooves 13 are opened on the outer walls of the shell 1. When the multiple guard plates 11 are close to the outer wall of the shell 1, the heat generated by the entire capacitor during operation is dissipated outward through the multiple grooves 13 and the multiple heat dissipation grooves 12 in turn, thereby improving the heat dissipation performance of the entire capacitor.
