Description

Technical Field

[0001] The utility model belongs to the technical field of wiring terminals, and in particular relates to a wiring terminal. Background Art

[0002] Gas-filled high-voltage switchgear is a type of high-voltage electrical equipment used in power systems, primarily for power distribution, control, and protection in distribution networks. This type of switchgear uses insulating gas (usually sulfur hexafluoride SF6 or other inert gases) as an insulating medium to improve the insulation performance and arc extinguishing capability of the switchgear. When the gas-filled high-voltage switchgear is connected to an external circuit, the terminal blocks need to be sealed and installed on the gas-filled high-voltage switchgear and connected to external equipment through the terminal blocks.

[0003] At present, the Chinese patent with authorization announcement number CN209946289U discloses a low-voltage test box sealed lead hole terminal, including a blind flange and a copper terminal. The inner side of the blind flange is provided with a mounting hole, and a fixing sleeve is provided in the mounting hole. A docking rod is fixed on the inner wall of the mounting hole, and the docking rod is located in the docking groove, and the docking groove is provided on the outside of the fixing sleeve. A limit plate is provided on the fixing sleeve, and a positioning plate is provided on the outside of the fixing sleeve. The edge end of the copper terminal is provided with a winding end, and a locking sleeve is provided on the winding end, and a conductive wire is wound around the outside of the winding end. The low-voltage test box sealed lead hole terminal has a sealed structure, high insulation and temperature resistance, and is particularly suitable for use in test boxes in simulated harsh environments. The copper terminal method is suitable for large current connections and is durable. At the same time, the blind flange integrated installation method is flexible and convenient for installation and connection in the equipment. However, when this technical solution is used in high-voltage circuits, due to the lack of insulation between the copper terminals, electric shock or short circuit may occur due to insufficient distance between the copper terminals, affecting use.
