Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to the attached drawings 1-5, the replaceable modular capacitor cabinet comprises a cabinet body 1, a plurality of partition plates 2 and drawer units 3, wherein the partition plates 2 are vertically arranged in the cabinet body 1 at intervals. The cabinet body 1 comprises a vertical column 11 which is vertically arranged, and the partition board 2 is arranged in the cabinet body perpendicular to the vertical column 11. The partition board 2 is horizontally arranged in the cabinet body 100, the drawer units 3 are slidably arranged on the partition board 2, wherein two drawer units are adjacently arranged on the partition board 2, two sets of slide rails 21 are arranged on the partition board 2, a set of slide sheet 31 is respectively arranged below each drawer unit, and each set of slide sheet 31 is adapted to slide on the slide rail 21 at the corresponding position; the two drawer units are respectively a first drawer unit 301 and a second drawer unit 302, a control module is arranged in the first drawer unit 301, and a capacitance module 303 is arranged in the second drawer unit 302. In this embodiment, a plurality of partition boards 2 are vertically arranged in the cabinet 1 at intervals, and a first drawer unit 301 and a second drawer unit 302 are adjacently placed on each partition board.

In this embodiment, the drawer unit 3 includes a front plate 35, a rear plate 36, a bottom plate 32, a left side plate 33 and a right side plate 34, the left side plate 33 and the right side plate 34 are installed between the front plate 35 and the rear plate 36, a handle 38 is installed on the front plate, and the handle 38 is used for holding the door to open and close. The bottom plate 32 is installed between the left side plate 33 and the right side plate 34, and more specifically, the bottom plate 32 has bending portions 321 extending upward on both sides, and the bending portions 321 are fastened to the left side plate 33 and the right side plate 34 by bolts. The lower ends of the left side plate 33 and the right side plate 34 extend downward and inward relative to the bottom plate to form sliding pieces, and the sliding pieces 31 are parallel to the bottom plate 32 and keep a constant distance with the bottom plate 32.

The slide rail 21 comprises a bottom sheet 211, a longitudinal section 212 and a transverse section 213, wherein the bottom sheet 211 is attached to the partition board 2, and the longitudinal section 212 is connected to the bottom sheet 211 and extends upwards; the transverse section 213 has one end connected to the longitudinal section 212 and the other end extending to the outside in the horizontal direction.
