Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] This utility model provides a technical solution: A type of power capacitor, please refer to Figures 1-7 It includes a power capacitor body 10, a lead-out rod 11 located on the top of the power capacitor body 10, and mounting bases 40 located on both sides of the power capacitor body 10, such as Figure 1 As shown, the mounting base 40 in the prior art is directly fixed on the power capacitor body 10. The position of the mounting base 40 is fixed. In actual outdoor installation, the mounting bases 40 on both sides of the power capacitor are generally installed on the crossbeam. Sometimes there are other devices installed below or above the crossbeam. In this way, the bottom of the power capacitor body 10 may sometimes cause positional interference with other devices, resulting in the need to adjust the installation position of the power capacitor body 10, which brings inconvenience to the installation work.

[0023] This application provides an adjustment component for adjusting the position of the mounting base 40 in the height direction of the power capacitor body 10. When the power capacitor body 10 is installed and encounters interference from other devices below (or above) it, the position of the mounting base 40 can be adjusted so that the mounting base 40 will not touch other devices after installation, which greatly improves the practicality of the device.

[0024] Specifically, the adjustment component has two parallel strips 30, which are vertically arranged and fixedly connected to the side wall of the power capacitor body 10. The strips 30 have a strip groove 300 along their height direction. The mounting base 40 is U-shaped, and threaded posts 401 are fixedly connected to both sides of the mounting base 40. The threaded posts 401 pass through the strip groove 300 and are threadedly connected to nuts 402. The mounting base 40 can be locked onto the strips 30 by the nuts 402.

[0025] It is worth noting that the strip 30 is also provided with a vertically arranged guide groove on the side near the mounting base 40, and a guide block is fixedly provided on the side wall of the mounting base 40. The guide block is slidably arranged in the guide groove, so that the mounting base 40 will not rotate when the mounting base 40 is raised or lowered.

[0026] The mounting base 40 has mounting holes 400 for easy installation.

[0027] The protective assembly is used to protect the lead-out rod 11. The protective assembly includes a cover plate 21 and at least one protective frame 20. In actual production, the length of the lead-out rod 11 on the top of the power capacitor body 10 of the same size and model will be different (different lengths of lead-out rod 11 will be installed according to actual wiring requirements or customer order requirements).

[0028] Depending on the length of the cable outlet rod 11, one or more protective frames 20 can be selected for protection. When the height of a protective frame 20 is greater than the length of the cable outlet rod 11, only one protective frame 20 is needed; otherwise, multiple protective frames 20 can be selected.

[0029] The two adjacent protective frames 20 are detachably stacked together. The lower protective frame 20 is detachably mounted on top of the power capacitor body 10, and the cover plate 21 is detachably connected to the top of the upper protective frame 20.

[0030] Each of the four bottom corners of the protective frame 20 is provided with a first positioning groove 200, and each of the four top corners of the protective frame 20 is fixedly connected with a protruding post 202; the protruding post 202 is adapted to the size of the first positioning groove 200; for two adjacent protective frames 20, the protruding post 202 on the top of one protective frame 20 can be inserted into the first positioning groove 200 at the bottom of the other protective frame 20.

[0031] The side wall of the protective frame 20 is provided with a first threaded hole 201 that communicates with the first positioning groove 200, and also includes a locking bolt 22. The locking bolt 22 is threadedly adapted to the first threaded hole 201. Tightening the locking bolt 22 can make the end of the locking bolt 22 abut against the protrusion 202, which can fix the upper and lower protective frames 20 together. Of course, multiple protective frames 20 can be stacked and installed according to actual needs.

[0032] Positioning posts 12 are fixedly connected to the top four corners of the power capacitor body 10. The positioning posts 12 are the same as the protruding posts 202. The first positioning groove 200 at the bottom of the protective frame 20 can be inserted into the protruding post 202. At this time, tightening the locking bolt 22 can make the end of the locking bolt 22 abut against the positioning post 12, and the protective frame 20 can be fixed to the top of the power capacitor body 10.

[0033] The cover plate 21 has a second positioning groove 210 at each of the four corners of the bottom. The second positioning groove 210 is the same as the first positioning groove 200. The protrusion 202 can be inserted into the second positioning groove 210 at the bottom of the cover plate 21.

[0034] The side wall of the cover plate 21 is provided with a second threaded hole 211 that communicates with the second positioning groove 210. The second threaded hole 211 is the same as the first threaded hole 201. The locking bolt 22 is threadedly matched with the second threaded hole 211. When the locking bolt 22 is tightened, the cover plate 21 can be fixed on the protective frame 20.

[0035] The cover plate 21 and the protective frame 20 can protect the outlet rod 11 and prevent it from being damaged by collision during transportation; the cover plate 21 and the protective frame 20 can be removed before the power capacitor is put into use.
