[0001] The utility model relates to the technical field of capacitors, in particular to a dual-capacitance capacitor with a heat insulation plate. Background Art

[0002] An intelligent capacitor is an intelligent reactive power compensation device integrating advanced technologies such as modern measurement and control, power electronics, network communication, automatic control, and power capacitors.

[0003] In order to improve the heat dissipation effect and prevent the heat emitted by the two cores from radiating to each other during operation, the dual-capacity intelligent capacitor developed by our company before (such as the application number CN2023205788114) separates the two cores by packaging them in the core housings to improve its heat dissipation effect. However, in actual applications, the separation setting cannot effectively isolate the mutual radiation of heat. To further improve the isolation effect between the two cores, this application proposes a dual-capacitance capacitor with a heat insulation plate. Summary of the Utility Model

[0004] Aiming at the deficiencies in the background art, the utility model provides a dual-capacitance capacitor with a heat insulation plate.

[0005] The technical solution adopted by the utility model is: a dual-capacitance capacitor with a heat insulation plate, including two core housings for installing capacitor cores and a shell cover for connecting and fixing the two core housings into a whole, and there is a spacing between the two core housings, and heat insulation plates are detachably connected to the core housings on both sides of the spacing.

[0006] Further, installation steps are formed by protruding on the core housings on both sides of the spacing, connection grooves are arranged along the length direction of the installation steps, and connection heads that are mutually engaged with the connection grooves are arranged on both sides of the heat insulation plate.

[0007] Further, the connection grooves are in a dovetail structure, and the ends of the connection heads have dovetail structures connected to the above connection grooves.

[0008] Further, arc-shaped wrapping surfaces that are consistent with the radian of the corners of the core housings are arranged on both sides of the end of the heat insulation plate.

[0009] Further, an inward arc-shaped concave surface is arranged at the end of the heat insulation plate.

[0010] Further, the ends of both ends of the heat insulation plate do not extend out of both sides of the core housing.

[0011] Further, positioning steps are arranged on the inner side wall of the shell cover.

[0012] The beneficial effects of the utility model are:

[0013] 1. Significantly improve thermal management performance: The introduction of the heat insulation board effectively prevents the heat generated by the two capacitor cores from radiating to each other during operation, thereby greatly improving the overall heat dissipation efficiency of the capacitor. The presence of the heat insulation board can better isolate the heat radiation generated by the two cores during operation, avoiding mutual influence, ensuring that each capacitor core can operate under better temperature conditions, and extending the service life of the capacitor.

[0014] 2. Enhance system stability and reliability: Reduce the risk of capacitor aging and performance degradation caused by overheating, and improve the stability and reliability of the system. The heat insulation measures help to maintain the operating temperature of the capacitor core within the design range, reduce the failure rate, and lower the maintenance cost.

[0015] 3. The heat insulation board is convenient to disassemble and assemble:

[0016] The design of the detachable heat insulation board not only facilitates the assembly and maintenance of the capacitor, but also allows users to replace different specifications of heat insulation materials according to the actual working conditions to meet different environmental requirements.

[0017] In addition to the purposes, features, and advantages described above, the present utility model has other purposes, features, and advantages.

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0025] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) involved in the embodiments of the present invention, the directional indications are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly.

[0026] The present invention provides a double-capacitance capacitor with a heat insulation plate.

[0027] In this embodiment, referring to Figures 1-4 , the double-capacitance capacitor with a heat insulation plate includes two core housings 1 for installing capacitor cores and a shell cover 2 for connecting and fixing the two core housings into a whole. There is a spacing 3 between the two core housings, and heat insulation plates 4 are detachably connected to the core housings on both sides of the spacing.

[0028] In the above technical solution, by providing a detachably connected heat insulation plate between the two core housings, the heat generated during the operation of the two capacitor cores is effectively isolated, preventing the heat radiation from affecting the performance of adjacent cores, thereby improving the overall heat dissipation effect and the operation stability of the device. The detachable heat insulation plate design facilitates maintenance and replacement, improving the flexibility and maintenance convenience of the device.

[0029] Specifically, installation steps 5 are formed by protrusions on the core housings on both sides of the spacing, and connection grooves 6 are provided along the length direction of the installation steps. Connection heads 7 that are mutually engaged with the connection grooves are provided on both sides of the heat insulation plate.

[0030] In the above technical solution, installation steps are provided on the core housings, and connection grooves are provided on the installation steps for connecting with the connection heads on the heat insulation plate, ensuring the firm connection of the heat insulation plate. The engagement structure of the connection heads and the connection grooves simplifies the installation process of the heat insulation plate and facilitates the disassembly and replacement of the heat insulation plate.

[0031] Specifically, the connection groove is a dovetail structure, and the end of the connection head has a dovetail structure connected to the above connection groove.

[0032] In this embodiment, the dovetail structure connection groove and connection head can provide stronger connection strength, prevent loosening during long-term use, and ensure the stability and durability of the heat insulation plate.

[0033] Specifically, both sides of the end of the heat insulation plate are provided with arc-shaped covering surfaces 8 that are consistent with the radian at the corner of the core housing.

[0034] In this embodiment, the design of the arc-shaped covering surface makes the contact between the heat insulation plate and the core housing more fitting, reduces the air gap, and improves the heat insulation effect. The arc-shaped covering surface can also reduce the eddy current inside the device, reduce the wind resistance, and contribute to improving the heat dissipation efficiency.

[0035] Specifically, the end of the heat insulation plate has an inward arc-shaped concave surface 9; the ends of both ends of the heat insulation plate do not protrude from both sides of the core housing.

[0036] In this embodiment, by restricting the ends of both ends of the heat insulation plate not to exceed both sides of the core housing, the influence of the external environment on the heat insulation plate can be reduced, and it is ensured that the installation of the heat insulation plate will not affect the original external shape structure of the capacitor.

[0037] Specifically, a positioning step 10 is provided on the inner side wall of the shell cover.

[0038] In this embodiment, when the core housing and the shell cover are assembled, the core housing and the shell cover need to be sleeved and fixed by screws. By setting the positioning step, the positioning of the sleeved position of the two can be carried out. When screwing, there is no need to find holes and align them, which improves the assembly efficiency.

[0039] All technical personnel should note that although the present utility model has been described according to the above specific embodiments, the idea of the present utility model is not limited to this utility model only. Any modification using the idea of the present utility model will be included in the protection scope of this patent right.
