[0029] The idea of ​​the present application is to design an insulating base with strong universality in view of the current situation in which the insulating base in the prior art is difficult to simultaneously meet the requirements of weather resistance, corrosion resistance, heavy pressure resistance and insulation. The insulating base makes reasonable design adjustments to the structure according to different altitudes, different pressure resistance levels, different load-bearing and insulation requirements. While ensuring the structural strength and load-bearing capacity, it has a higher pressure resistance requirement, ensures the electrical distance and creepage distance, and provides better electrical protection for electrical equipment.

[0030] The technical solutions provided by various embodiments of the present application are described in detail below in conjunction with the accompanying drawings.

[0031] The present application embodiment provides an insulating base and a high-voltage electrical device, such as Figure 1 As shown, an isometric view of an insulating base in an embodiment of the present application is provided, wherein the insulating base comprises: an insulating wing plate and an insulating web 2, wherein at least two insulating wing plates are arranged in parallel; the insulating web 2 is arranged perpendicularly to the at least two insulating wing plates, and sub-wing plates of different cross sections are arranged between the at least two insulating wing plates. Figure 1 The insulating base in the embodiment is a preferred embodiment in the specific implementation. As an embodiment in the present application, the insulating wing plate may include three insulating wing plates, and the shape and structure of the insulating wing plates may be the same or different. In the specific implementation, in combination with aesthetics and practicality, a single insulating wing plate is in a regular three-dimensional geometric shape, such as a cuboid; the top insulating wing plate and the bottom insulating wing plate have the same shape, such as a cuboid. The insulating web 2 in the present application is perpendicular to the insulating wing plate and passes through the insulating wing plate (sub-wing plate) in the middle position in the insulating base.

[0032] like Figure 1-5 As shown, in some examples of the present application, the edge wing panel includes an upper wing panel 1 and a lower wing panel 6, and the sub-wing panel includes at least one middle wing panel, wherein the upper wing panel 1 is located at the top of the middle wing panel, and the lower wing panel 6 is located at the bottom of the middle wing panel.

[0033] During specific implementation, the upper wing panel 1 and the lower wing panel 6 in the present application have the same shape, both of which are cubic plates. In consideration of aesthetic needs, the shortest corners of the upper wing panel 1 and the lower wing panel 6 are set to an arc-shaped structure for easy transportation and placement; the middle wing panel includes multiple ones with the same or different shapes. Taking the present application as an example, the middle wing panel includes a middle large wing panel 4 and a middle small wing panel 5, wherein at least one middle small wing panel 5 is arranged between every two middle large wing panels 4. In the present application, the middle large wing panel 4 and the middle small wing panel 5 are placed in a certain pattern, such as the middle large wing panel 4 and the middle small wing panel 5 are placed one or more apart from each other, or as in the present application. Figure 1-5 As shown in the regular arrangement, two middle small wing panels 5 are placed between two adjacent middle large wing panels 4, and the upper wing panel 1 and the lower wing panel 6 are placed outside the outermost middle large wing panel 4. In the present application, the cross-section of the middle large wing panel 4 and the middle small wing panel 5 is one of the following shapes: rhombus, rectangle, triangle.

[0034] like Figure 1 As shown, in the present application, the insulating web 2 passes through each of the middle wing plates, and a reinforcing rib 3 perpendicular to the insulating wing plates is provided on the insulating web 2. Since the material of the insulating base in the present application is solid SMC material, and the entire insulating base is integrally formed, the insulating wing plates visually divide the insulating web 2.

[0035] In some examples of the present application, the reinforcing ribs include a plurality of reinforcing ribs, which are respectively arranged at the middle position and edge position of the insulating web. The cross section of the reinforcing ribs is one of the following shapes: triangle, rectangle, circle, diamond, ellipse;

[0036] like Figure 1 As shown, a plurality of reinforcing ribs 3 are respectively arranged at the middle and edge positions of the insulating web 2. The reinforcing ribs arranged at the middle and edge are located on both sides of the insulating web 2 and are fixed integrally with the web. The cross-sectional shape of the reinforcing ribs 3 includes but is not limited to triangle, rectangle, circle, rhombus, ellipse, and semicircle.

[0037] like Figure 1-5 As shown, the middle large wing plate 4 and the middle small wing plate 5 are plate-shaped as a whole. In order to cast them as one and save materials, the middle large wing plate 4 and the middle small wing plate 5 are thick in the middle and thin on both sides. The shapes of their transverse cross-sections include but are not limited to rhombus, rectangle, and triangle.

[0038] In some examples of this application, Figure 2 For example, the upper wing plate 1 and the lower wing plate 6 are respectively connected to the middle wing plate and the insulating web 2 on two transverse free surfaces thereof, and a plurality of longitudinal protrusions are arranged. Figure 2 For example, as a specific embodiment of the present application, the insulating base in the present application is symmetrical left-right and front-back.

[0039] In some examples of the present application, the corners of the middle wing plate are arc-shaped, which is convenient for safe handling and pouring; the upper wing plate 1 and the lower wing plate 6 are respectively provided with a plurality of circular holes or through holes. The insulating base is made of SMC insulating material. The upper wing plate 1 has 6 circular holes for fixing the battery rack or cabinet, and the lower wing plate 6 has 4 circular holes for fixing the insulating base.

[0040] The insulating base in the present application can meet the requirements of 3000-meter high-altitude insulation and 125KV high-voltage withstand, with a creepage distance of not less than 1.1 meters and a single load-bearing capacity of not less than 450KG; in addition, the insulating base in the present application is easy to process and can be formed in one piece.

[0041] It can be understood that the insulating base in this application uses a one-time molding process, which greatly shortens the processing and manufacturing cycle compared to traditional subtractive processing while saving materials. According to the load-bearing and insulation requirements of the insulating base at different altitudes and different voltage resistance levels, the structure is reasonably designed and adjusted to ensure the structural strength, that is, the load-bearing capacity, while bearing higher voltage requirements, ensuring the electrical distance and creepage distance, and providing better electrical protection.
