[0032] When installing the capacitor body 3 or the reactor 4, the capacitor body 3 or the reactor 4 is pushed inward, thereby pushing the push plate 9 through the capacitor body 3 or the reactor 4, and the push plate 9 drives the rack 8 to move, and the rack 8 drives the first rod 5 to rotate. The first rod 5 drives the clamping member 13 to move upward through the rotation and connection relationship, and clamps the capacitor or the reactor 4 from the bottom of the capacitor body 3 or the reactor 4.

[0033] When the capacitor body 3 or the reactor 4 needs to be clamped, the capacitor body 3 or the reactor 4 is held and attached to the push plate 9, and then the capacitor body 3 or the reactor 4 is pushed, and the capacitor body 3 or the reactor 4 is pushed inward, so that the push plate 9 is pushed by the capacitor body 3 or the reactor 4. During the movement of the capacitor body 3 or the reactor 4, the first telescopic rod 11 is driven to shorten by the second telescopic rod 12, so that the clamping member 13 moves inward with the capacitor body 3 or the reactor 4, thereby ensuring that the upper and lower positions of the capacitor body 3 or the reactor 4 and the clamping member 13 are always aligned, the push plate 9 drives the rack 8 to move, and the rack 8 drives the first rod 5 to rotate, and the first rod 5 drives the clamping member 13 to move upward through the rotation and connection relationship, and clamps the capacitor or the reactor 4 from the bottom of the capacitor body 3 or the reactor 4. When the clamping state is to be released, the first rod 5 can be rotated in the opposite direction.

[0034] As can be seen from the above, the present invention does not require additional rotation of other components when clamping and installing the capacitor body 3 or the reactor 4, thereby improving the convenience of operation.

The upper baffle 15 is provided with a through groove 18, and the lower baffle 17 is provided with a protrusion 19 that cooperates with the through groove 18.

[0037] In the prior art, in order to improve the heat dissipation effect of the capacitor body 3 or the reactor 4, the capacitor body 3 or the reactor 4 is usually exposed to the outside. However, external force may occur during transportation. In order to reduce the damage to the capacitor by external force, the present invention designs a lower baffle 17. During transportation, the lower baffle 17 can be lowered to block the capacitor body 3 or the reactor 4, thereby achieving a protective effect. When heat dissipation is required, the lower baffle 17 is moved up so that the protrusion 19 cooperates with the through groove 18, and the lower baffle 17 is fixed at the upper end without affecting the heat dissipation of the capacitor body 3 or the reactor 4.

[0038] In order to further improve the heat dissipation effect, in some embodiments, the upper baffle plate 15 and the lower baffle plate 17 are provided with a circular through hole 20 in the middle, and a plurality of annularly distributed mounting plates 21 are provided at the circular through hole 20 of the upper baffle plate 15, and the mounting plates 21 have threaded mounting holes, and the threaded mounting holes are used to install fans or strip plates.

[0040] When it is necessary to disassemble the clamping member 13 and the base frame 1 and the side assembly as a whole, by rotating the first rod 5, the first rod 5 will drive the screw 22 to rotate through the connection relationship. When the thread on the screw 22 is separated from the thread in the second positioning hole, the disassembly of the screw 22 on the base frame 1 is completed. When it is necessary to disassemble the positioning member and thus disassemble the side assembly, the lower baffle 17 is lowered at this time, and then the lower baffle 17 is tilted upward to push the first connecting rod 26 to move upward. The first connecting rod 26 moves upward and drives the third connecting rod 28 to move toward the middle of the shell 2 through the second connecting rod 27, so that the third connecting rod 28 leaves the positioning member and releases the limitation on the positioning member. At this time, the positioning member can be directly taken out to realize the removal of the positioning member on the side assembly. After the screw 22 and the positioning member are removed, the base frame 1 and the side assembly can be disassembled as a whole, which is convenient for subsequent maintenance.

[0041] In some embodiments, a plurality of waist-shaped holes are provided on the base frame 1. The capacitor is installed as a whole at a desired position through the waist-shaped holes.
