Description

Technical Field

[0001] This utility model relates to the field of power copper busbar technology, and in particular to an insulating support device for a rectifier valve side copper busbar. Background Technology

[0002] In the chlor-alkali industry production process, the rectifier system is one of the core equipment, and its rectifier valve side copper busbar undertakes the key task of converting AC power into DC power and transmitting it to the electrolytic cell.

[0003] Currently, the copper busbar supports on the rectifier valve side in the industry generally suffer from the following common problems, which seriously affect production safety and efficiency. Due to the presence of large amounts of dust in the chlor-alkali production environment (such as salt dust, alkali mist condensation dust, etc.), dust easily accumulates on the surface of the copper busbar. As operating time increases, the increased thickness of the accumulated dust leads to a decrease in the insulation resistance of the copper busbar, easily causing phase-to-phase or phase-to-ground short circuits. Furthermore, traditional copper busbar support structures are simple and cannot provide stable support, resulting in unsatisfactory performance.

[0004] Therefore, there is an urgent need for a support device that can provide stable insulation support for copper busbars and has a dustproof effect. Utility Model Content

[0005] The purpose of this invention is to solve the above-mentioned problems by providing an insulating support device for the rectifier valve side copper busbar that can provide stable insulating support for the copper busbar, has a dustproof effect, and ensures the stability of power transmission of the copper busbar.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows: an insulating support device for a rectifier valve side copper busbar, comprising a base and a support seat fixed above the base. The support seat has a through slot, and an elastic clamping mechanism and a copper busbar are provided in the slot. The upper and lower surfaces of the copper busbar are in contact with the elastic clamping mechanism. Both ends of the copper busbar are provided with insulating ends, and the insulating ends are provided with downwardly extending terminals. The terminals are in contact with the copper busbar in the insulating ends. Dust covers are provided on both sides of the support seat.

[0007] Preferably, the elastic clamping mechanism includes upper and lower clamping plates, both ends of which are provided with arc-shaped flanges. The clamping plates are connected to the inner wall of the slot through springs, and the clamping plates compress the springs when the copper busbar is inserted.

[0008] Preferably, the support base is further provided with insulating positioning bolts on both sides, and the positioning bolts extend into the slot and abut against both sides of the copper busbar.

[0009] Preferably, the dust cover is located directly above the copper busbar, and both sides are fixedly connected to the support base at the side plate by fixing bolts.

[0010] Preferably, the dust cover is U-shaped, and the inner wall of the dust cover does not contact the outer surface of the copper busbar.

[0011] Preferably, both the support base and the insulating positioning bolt are made of ceramic material.

[0012] This utility model discloses an insulating support device for a rectifier valve side copper busbar, including a base and a support seat fixed above the base. The support seat has a through slot, and an elastic clamping mechanism and a copper busbar are arranged in the slot. The upper and lower surfaces of the copper busbar are in contact with the elastic clamping mechanism. Both ends of the copper busbar are provided with insulating ends, and the insulating ends are provided with downwardly extending terminals. The terminals are in contact with the copper busbar in the insulating ends. Dust covers are provided on both sides of the support seat. The elastic clamping mechanism includes upper and lower clamping plates, and both ends of the clamping plates are provided with arc-shaped flanges. The clamping plates are connected to the inner wall of the slot by springs. When the copper busbar is inserted, the clamping plates compress the springs. Compared with the prior art, this insulating support device for a rectifier valve side copper busbar has the beneficial effects of providing stable insulating support for the copper busbar and dust prevention, thus ensuring the stability of power transmission of the copper busbar.

[0017] The present invention will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0018] Please refer to Figure 1-3An insulating support device for a rectifier valve side copper busbar includes a base 1 and a support base 2 fixed above the base 1. The base 1 has mounting holes at its four corners, and the entire assembly is fixed by bolts. The support base 2 has a through slot 3, and the slot 3 contains an elastic clamping mechanism and a copper busbar 4. The upper and lower surfaces of the copper busbar 4 are in contact with the elastic clamping mechanism. Both ends of the copper busbar 4 are provided with insulating ends 5, and the insulating ends 5 contain downwardly extending terminals 6. The terminals 6 are in contact with the copper busbar 4 within the insulating ends 5. Dust covers 7 are provided on both sides of the support base 2.

[0019] In the chlor-alkali workshop, the copper busbar on the rectifier valve side is responsible for converting AC power to DC power and transmitting the power to the electrolytic cell. During use, the copper busbar 4 can be effectively supported by the support seat 2, which not only provides insulation but also prevents dust from accumulating on the surface of the copper busbar, thus avoiding short circuits caused by dust and affecting the normal production progress.

[0020] Specifically, the elastic clamping mechanism includes two clamping plates 31, one above the other. Both ends of the clamping plates 31 are provided with arc-shaped flanges 32. The bending directions of the two arc-shaped flanges 32 on the same side are opposite. The clamping plates 31 are connected to the inner wall of the slot 3 through springs 33. When the copper busbar 4 is inserted, the clamping plates 31 compress the springs.

[0021] In this embodiment, the arc-shaped flange 32 at the end of the clamping plate 31 can provide a guiding function for the insertion of the copper busbar 4, so that the copper busbar 4 can be smoothly inserted between the two clamping plates 31; after insertion, the spring 33 is compressed and contracted, and at this time, the elastic thrust of the upper and lower springs 33 makes the clamping plate 31 clamp the copper busbar 4 to ensure the stability of the copper busbar.

[0022] In addition, due to the setting of spring 33, copper busbars of different thicknesses can be inserted, making it applicable to a wide range of applications.

[0023] Since the upper and lower surfaces of the copper busbar 4 are stably clamped, in order to further ensure the stability of the copper busbar, insulating positioning bolts 41 are provided on both sides of the support base 2. The positioning bolts 41 extend into the slot 3 and abut against both sides of the copper busbar 4. Therefore, the copper busbar can be limited in four directions to ensure the stability of use.

[0024] In this embodiment, the dust cover 7 is located directly above the exposed part of the copper busbar 4, and both sides are fixedly connected to the support base 2 by fixing bolts 71 at the side plate.

[0025] During use, external dust eventually falls onto the dust cover 7, preventing dust from directly contacting the copper busbar 4 and avoiding short circuits caused by dust accumulation.

[0026] When cleaning is required, remove the fixing bolts 71, and then manually clean the dust on the outside of the dust cover 7.

[0027] Furthermore, the dust cover 7 is U-shaped, and the inner wall of the dust cover 7 does not contact the outer surface of the copper busbar 4, thus avoiding interference between the two.

[0028] As a preferred option, the dust cover 7 can be made of insulating materials such as plastic, ceramic or rubber.

[0029] As a preferred embodiment, both the support base 2 and the insulating positioning bolt 41 are made of ceramic material, which ensures both insulation and dust prevention, while also meeting the conductivity requirements of the copper busbar.

[0030] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
