Description

Technical Field

[0001] The utility model belongs to the technical field of electrical engineering, and in particular relates to a high-voltage lead converging device which is convenient for installing high-voltage cables. Background Art

[0002] High-voltage lead-in busbars are key components in electrical equipment used to connect and distribute high-voltage electrical energy. They are widely used in power transmission systems, high-voltage test equipment, power transformers, high-voltage switchgear, and various high-voltage test and measurement instruments. Their primary function is to safely and efficiently introduce high-voltage power to equipment or systems requiring electrical energy and ensure stable distribution of that energy.

[0003] In existing technologies, high-voltage lead-manifolds are often integrated into the internal frame of equipment or fixed in specific locations to facilitate the smooth transmission of electrical energy to the various terminals requiring it. Welding is often used as a fixing method to securely connect the high-voltage lead-manifold to the target structure. However, over long-term operation, welded joints may experience issues such as aging, thermal stress damage, and corrosion, which can affect the reliability and service life of the system. Therefore, a high-voltage lead-manifold that facilitates the installation of high-voltage cables is proposed. Utility Model Content

[0004] The purpose of the present utility model is to provide a high-voltage lead-in merging device that is convenient for the installation of high-voltage cables, aiming to solve the problem in the prior art that welding joints may face problems such as aging, thermal stress damage and corrosion during long-term operation, thereby affecting the reliability and service life of the system.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a high-voltage lead busbar device that facilitates the installation of high-voltage cables, comprising:

[0006] device body;

[0007] A plurality of first grooves, wherein the plurality of first grooves are respectively formed at both side ends of the device body;

[0008] A plurality of silicone rubber cylinders, each of which is fixedly connected to one side inner wall of the plurality of first grooves;

[0009] A plurality of clamping blocks are respectively arranged at one side end of the plurality of first grooves.

[0010] As a preferred solution of the present invention, one side end of the device body is fixedly connected to a drainage tube, and one side end of the drainage tube is provided with a drainage port.

[0011] As a preferred solution of the present invention, a second clamping plate is provided on the circumferential inner wall of the drainage tube, a first rotating shaft is provided on the circumferential surface of the second clamping plate, and a first turning handle is fixedly connected to the top end of the first rotating shaft.

[0012] As a preferred solution of the present invention, a plurality of diversion tubes are fixedly connected to the other side end of the device body, and a diversion port is formed at one side end of each of the plurality of diversion tubes.

[0013] As a preferred solution of the present invention, the circumferential inner walls of the multiple diversion ports are provided with a first clamping plate, the circumferential surfaces of the multiple first clamping plates are provided with a second rotating shaft, and the top ends of the multiple second rotating shafts are fixedly connected with a second handle.

[0014] As a preferred solution of the present invention, the material of the device body is epoxy resin, polyimide, and ceramic insulator from the inside to the outside, and a second groove is opened on one side end of the device body.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. This device innovatively integrates a design that enhances safety and facilitates installation, employing sophisticated engineering strategies to ensure efficient operation and long-term durability. Its core components are multiple silicone rubber cylinders equipped with insulating springs. These cylinders not only possess excellent resilience, but are also supplemented by high-performance insulating springs along their circumference, effectively enhancing both insulation and elasticity. During installation, the user simply applies pressure to one end of the intelligently designed latches, causing them to cleverly snap into place within the pre-set first groove. This allows the device to be precisely positioned. Once the pressure is released, the elastic force within the silicone rubber cylinders, combined with the support of the surrounding springs, allows the latches to snap securely into the target mounting surface, ensuring a secure connection. Operation is simple and quick. Crucially, all contact surfaces, including the silicone rubber cylinders and latches, are constructed from high-quality insulating materials. This design effectively prevents the risk of electrical leakage caused by high-voltage currents, enhancing operational safety. Compared to traditional solutions where welded joints may be subject to aging, thermal stress damage, and corrosion, this device, through its superior material selection and structural design, significantly enhances system reliability and extends service life, providing a reliable installation solution for equipment operating in high-voltage environments.

[0017] 2. In this solution, the cable to be drained is placed through the drainage port, and then the first handle is rotated. This action not only drives the drainage tube to rotate flexibly, but also prompts the first rotating shaft to move downward precisely vertically, thereby tightening and limiting the cable. This design effectively prevents the cable from accidentally falling off due to external interference, ensuring the continuity and stability of the operation. Following the same principle, when the cable to be diverted is placed in place through the diversion port, the operator turns the second handle. This operation not only causes the second rotating shaft to start rotating, but also simultaneously guides the first clamping plate to move downward, accurately locking the diversion cable. This once again reflects the high attention paid to the stability of the cable, eliminating any potential risk of cable loosening during operation. BRIEF DESCRIPTION OF THE DRAWINGS
