Description

Technical Field

[0001] This utility model relates to the field of high-voltage voltage testing grounding ring technology, and in particular to a voltage testing grounding ring with lightning protection function. Background Technology

[0002] Grounding refers to the connection between the neutral point of a power system and electrical installations, the exposed conductive parts of electrical equipment, and the external conductive parts of the installations, and the earth via a conductor. It can be divided into functional grounding, lightning protection grounding, and protective grounding. A grounding ring is a type of grounding device; a lightning protection grounding ring is a protective device used to prevent overhead insulated conductors from breaking due to lightning strikes, and also for voltage testing and temporary grounding during maintenance and construction.

[0003] To prevent lightning strikes from breaking overhead insulated conductors, arc-damping devices need to be installed on the load side of the insulators in the line. During maintenance and construction of overhead insulated lines, temporary grounding and voltage testing are required. Current grounding and voltage testing products do not provide adequate arc-damping protection. To address these shortcomings, we propose a voltage testing grounding ring with lightning protection capabilities. Utility Model Content

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Example 1, as Figures 1-4 As shown, a voltage detection and grounding ring with lightning protection function is used for voltage detection and temporary grounding protection of high-voltage cables during maintenance and construction work. An insulating sleeve 1 is installed onto the cable surface via a fixing shell 2. The insulating sleeve 1 has an inner aluminum ring 13 inside, which serves as a conductor. A mounting base 5 is inserted into the outer surface of the insulating sleeve 1. A conductive rod 14 is connected to the top of the inner aluminum ring 13. The conductive rod 14 passes through the mounting base 5 and connects to the fixing shell 2 at the top of the insulating sleeve 1. The fixing shell 2 protects the winding post 15 at the top of the conductive rod 14. Simultaneously, the grounding ring body is installed at the high-voltage conductor 3. The high-voltage conductor 3 is connected to the cable via a conductor clamp 6 passing through the side of the fixing shell 2. Inside the fixed shell 2, it connects to the winding stake 15, thereby conducting the current to the inner aluminum ring 13, enabling the device to perform current detection before construction, thus improving the safety of subsequent construction. After the conductor clamp 6 is connected to the high-voltage conductor 3, the fixing bolt 4 at the top can be used to reinforce the installation of the high-voltage conductor 3 and prevent the connection structure from falling off. At the same time, the grounding wire clamp 7 can be directly inserted into the outer wall of the inner aluminum ring 13, and the inner aluminum ring 13 is clamped by the clamping groove 18, so that the grounding wire clamp 7 and the inner aluminum ring 13 have an electrical connection. Through the conduction of the grounding wire clamp 7 and the cable 10, a temporary grounding function can be achieved. The grounding wire clamp 7 makes the assembly between the grounding structure and the grounding ring more convenient.

[0022] Example 2, as Figures 1-4 As shown, a grounding ring with lightning protection function has a lightning protection insulator 12 installed on the side of the grounding ring. The lightning protection insulator 12 is connected to the mounting slot 17 through the connecting seat 11 at the top. The lightning protection insulator 12 can be installed on the outer wall of the high-voltage conductor 3 through the mounting slot 17. The lightning protection insulator 12 provides lightning protection for the grounding ring. During operation, the arc-inducing ball 9 at the bottom of the grounding ring can conduct the electric arc generated by the lightning strike to the lightning protection insulator 12, preventing the grounding ring from being directly damaged by lightning strikes, thus improving the functionality and safety of the equipment.
