[0002] With the rapid development of new energy power generation, electric vehicle charging stations, data centers, industrial automation, and smart grids, the demand for reactive power compensation and harmonic control in power systems has become increasingly prominent and critical. As a core device for improving power factor, stabilizing grid voltage, and reducing line losses, capacitor compensation boxes are seeing their application scope expand and their technical requirements increase.
[0003] In existing technologies, capacitor banks typically employ a welded enclosure structure and a fixed internal layout. The manufacturing process involves cutting, stamping, and bending steel plates in a factory, then welding them together to form a rigid, non-removable enclosure. Capacitors, reactors, fuses, switching devices, and other components are then fixedly installed inside the enclosure according to a predetermined design. When an internal component fails and needs replacement, or when the user needs to increase or decrease capacity due to load changes, maintenance personnel must operate within the confined space of the enclosure, resulting in limited space and inconvenience. Utility Model Content

When maintenance of the internal electrical components of the capacitor box is required, only the corresponding mounting plate needs to be removed, which greatly facilitates the maintenance work and makes the operation more convenient.

[0009] As a preferred embodiment of this utility model, the second capacitor connection plate is installed on the front side of the capacitor, and the second capacitor connection plate is long and narrow.
[0010] As a preferred embodiment of this utility model, the resistor mounting plate is installed inside the outer casing, and two auxiliary mounting plates for wiring terminals are installed on both the left and right sides of the wiring terminal mounting plate, with the auxiliary mounting plates for wiring terminals installed inside the outer casing.

[0015] Example like Figures 1 to 6 As shown, an assembled capacitor box includes: an outer casing 1 and a capacitor 12. A first cover plate 2 is installed on the front side of the outer casing 1, a second cover plate 3 is installed on the bottom of the outer casing 1, a capacitor mounting plate 9 is installed on the top inner side of the outer casing 1, a first capacitor limiting plate 10 is installed on the bottom of the capacitor mounting plate 9, a second capacitor limiting plate 11 is provided on the front side of the capacitor mounting plate 9, a first capacitor connecting plate 13 is installed on the front side of the capacitor 12, second capacitor connecting plates 14 are provided on both the left and right sides of the first capacitor connecting plate 13, a third capacitor connecting plate 15 is installed on the bottom of the second capacitor connecting plate 14, a resistor mounting plate 16 and a terminal mounting plate 18 are provided directly below the capacitor 12, a resistor 17 is installed on the front side of the resistor mounting plate 16, and a terminal 19 is installed on the front side of the terminal mounting plate 18.
[0016] In this embodiment, the second capacitor limiting plate 11 is installed on the inner top of the outer casing 1. The capacitor 12 moves through the first capacitor limiting plate 10 and the second capacitor limiting plate 11. The first capacitor limiting plate 10 and the second capacitor limiting plate 11 limit the installation of the capacitor 12, which facilitates the maintenance of the capacitor 12.
[0017] In this embodiment, two hanging holes 4 are provided on the rear side of the outer casing 1 and the capacitor mounting plate 9 near the top, and two slots 5 are provided on the rear side of the outer casing 1 near the bottom. When installing the capacitor box, four screws are first installed on the mounting base, and the positions of the four screws correspond to the positions of the large holes of the slots 5 and the hanging holes 4, respectively. Then, the capacitor box is moved so that the large holes of the hanging holes 4 on the outer casing 1 and the capacitor mounting plate 9 correspond to the two upper screws. At this time, the slots 5 correspond to the two lower screws. Then, the capacitor box is moved downwards, and the slots 5 are engaged with the back of the screw nuts, while the two upper screws are engaged with the small holes of the hanging holes 4, thereby completing the installation of the capacitor box. The installation operation is simple; just move the capacitor box to the corresponding position and then move the capacitor box downwards.
[0018] In this embodiment, first heat dissipation holes 6 are provided on both the left and right sides of the outer casing 1, and second heat dissipation holes 7 and handle grooves 8 are provided on the second cover plate 3. The first heat dissipation holes 6 and second heat dissipation holes 7 improve the heat dissipation performance inside the capacitor box, and the handle grooves 8 facilitate the transfer of the capacitor box. In this embodiment, the second capacitor connection plate 14 is installed on the front side of the capacitor 12, and the second capacitor connection plate 14 is elongated.
[0019] In this embodiment, the resistor mounting plate 16 is installed inside the outer casing 1, and two auxiliary mounting plates 20 for wiring terminals are installed on both the left and right sides of the wiring terminal mounting plate 18. The auxiliary mounting plates 20 for wiring terminals are installed inside the outer casing 1. With the resistor mounting plate 16, the wiring terminal mounting plate 18 and the auxiliary mounting plates 20 for wiring terminals set up, when the resistor 17 or the wiring terminal 19 is damaged and needs to be replaced, only the corresponding mounting plate needs to be removed, which facilitates the maintenance work.
[0020] In this embodiment, a plurality of wiring slots 21 are provided on the front side of the terminal block 19, and the second capacitor connection plate 14 is installed inside the adjacent wiring slots 21.
[0021] Implementation plan: When installing capacitor 12, first install the first capacitor mounting plate 9 and the second capacitor limiting plate 11 on the inner top of the outer casing 1, then move capacitor 12 through the first capacitor limiting plate 10 and the second capacitor limiting plate 11, then move the first capacitor connecting plate 13 to connect and fix multiple capacitors 12, then install two second capacitor connecting plates 14 on capacitor 12, and finally install the third capacitor connecting plate 15 at the bottom of the second capacitor connecting plate 14.
[0022] Next, resistor 17 is installed on resistor mounting plate 16, and then resistor mounting plate 16 is installed on the bottom inner side of outer casing 1. Then, terminal 19 is installed on terminal mounting plate 18. Terminal mounting plate 18 is installed on the bottom inner cavity of outer casing 1 through terminal auxiliary mounting plate 20. Finally, third capacitor connecting plate 15 is installed in the inner cavity of wiring groove 21 on terminal 19.
[0023] When installing the capacitor box, first install four screws on the mounting base. The positions of the four screws correspond to the positions of the large holes in the slot 5 and the hanging hole 4, respectively. Then move the capacitor box so that the large holes in the hanging hole 4 on the outer casing 1 and the capacitor mounting plate 9 correspond to the two screws above. At this time, the slot 5 corresponds to the two screws below. Then move the capacitor box downwards. The slot 5 engages with the back of the screw nut, while the two screws above engage with the small holes in the hanging hole 4. This completes the installation of the capacitor box. The installation operation is simple. Just move the capacitor box to the corresponding position and then move the capacitor box downwards.
[0024] The capacitor 12, resistor 17 and terminal 19 of this device can be disassembled and installed as needed. When maintenance is required on the electrical components inside the capacitor box, only the corresponding mounting plate needs to be removed, which greatly facilitates the maintenance work and makes the operation more convenient.
