[0005] As a preferred technical solution of the utility model: bottom plates are provided on both sides of the base, and countersunk holes are also provided on the bottom plates, which are connected to the first support rod after passing bolts through the countersunk holes to complete the installation and fixation of the first support rod.

[0006] As a preferred technical solution of the utility model: a through hole is further provided on one side of the bottom plate away from the countersunk hole, and a bolt passes through the bottom plate and is connected to the inner bottom surface of the box body to complete the installation and fixation of the support frame.

DETAILED DESCRIPTION

[0019] Embodiments of the present utility model are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present utility model, and should not be construed as limitations on the present utility model. In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "upper surface", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the present utility model.

[0020] See also Figure 1-5 The utility model provides an embodiment: a low-voltage reactive power compensation cabinet, comprising a box body 1 and a support frame 2 movably installed in the box body 1; the support frame 2 comprises a base 20, one side of the base 20 is movably connected to a first support rod 21, and the other side of the base 20 is movably connected to a second support rod 23; the upper ends of the first support rod 21 and the second support rod 23 are both connected to the guide rail mounting frame 22 by axle pins; the base 20 is also provided with a mounting hole 24 for placing a capacitor, and a supporting plate 25 for supporting the capacitor is also provided below the base 20.

[0021] To summarize, since the guide rail mounting frame 22 rotates on the two support rods, the use angle of the guide rail mounting frame 22 can be adjusted, so as to facilitate the rotation of the wiring port of the electrical component to face the outside of the box body 1, thereby facilitating the connection between the wire and the electrical component; at the same time, due to the setting of the mounting hole 24, it is convenient to confine the capacitor on the base 20, and the setting of the support plate 25 can both support the capacitor and avoid direct contact between the capacitor and the bottom surface of the box body 1, so as to ensure that there is a sufficient air flow gap between the capacitor and the bottom surface of the box body, so as to enhance the heat dissipation capacity and corrosion resistance of the capacitor.

[0022] In addition, the support frame 2 of the device can be taken out from the inside of the box 1 as a whole, so the electrical components can be integrated on the support frame 2 in advance and then assembled with the box 1, and the assembly field of view outside the box 1 is better, which can further improve the assembly efficiency of the electrical components.

[0023] Since bottom plates 27 are provided on both sides of the base 20, and countersunk holes 26 are provided on the bottom plates 27, bolts are passed through the countersunk holes 26 and connected to the first support rods 21 to complete the installation and fixation of the first support rods 21. Therefore, the two support rods are convenient to be assembled and disassembled from the base 20, and the support rods of appropriate length can be selected according to the height inside the box body 1.

[0024] Furthermore, a through hole 28 is provided on one side of the bottom plate 27 away from the countersunk hole 26, and a bolt is passed through the bottom plate 27 to connect with the inner bottom surface of the box body 1 to complete the installation and fixation of the support frame 2. Therefore, the base 20 and the box body 1 can be easily disassembled and assembled. Based on this, when installing for the first time, the electrical components can be integrated into the support frame 2, and then connected to the box body 1 through the support frame 2 to complete the rapid assembly of the equipment; when it is used and maintained later, the support frame 2 can also be removed from the box body 1 as a whole. Since the support frame 2 can be removed as a whole, it can provide users with a wider field of view, so that users can inspect and replace the electrical components on the support frame 2.

[0025] On the basis of the above scheme, the upper end of the first support rod 21 is further provided with an axle pin hole 210, and the axle pin hole 210 is axle pin-connected with the axle pin rod 211 on the guide rail mounting frame 22, so as to facilitate the rotation of the guide rail mounting frame 22 between the first support rod 21 and the second support rod 23. Specifically, the axle pin rod 211 passes through the axle pin hole 210 and is connected with a nut, which facilitates the installation of the guide rail mounting frame 22 and also facilitates the rotation of the guide rail mounting frame 22. Specifically, the electrical components are first installed on the corresponding guide rail, and then the guide rail is installed on the guide rail mounting frame 22 by bolts.

[0026] Furthermore, since the first support rod 21 and the second support rod 23 have the same structure, and a protrusion 29 is also provided at the upper end of the first support rod 21, the protrusion 29 can be used to support the bottom side of the guide rail mounting frame 22, thereby preventing the guide rail mounting frame 22 from excessively rotating on the two support rods. At the same time, the protrusion 29 can also be used to make the outer side surface of the guide rail mounting frame 22 flush with the outer side surface of the box body 1, so that the electrical components on the guide rail mounting frame 22 work vertically, making the interior of the box body 1 more beautiful and elegant.

[0027] Furthermore, since the support plate 25 is placed horizontally directly below the mounting hole 24 and the width of the support plate 25 is smaller than the width of the mounting hole 24, when the bottom surface of the capacitor contacts the support plate 25, both ends of the capacitor can be exposed to the outside of the support plate 25, thereby increasing the contact surface between the airflow and the capacitor to improve the heat dissipation efficiency of the capacitor; in addition, by utilizing the cooperation between the mounting hole 24 and the support plate 25, the capacitor does not need other fasteners to be fixed while ensuring stable operation.

[0028] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
