Description

Technical Field

[0001] The utility model relates to the technical field of full-gas-filled cabinets, and more specifically, to an enlarged gas box inflation valve for a 10kV full-gas-filled cabinet. Background Art

[0002] The 10kV fully-filled switchgear, also known as a fully-insulated and fully-enclosed gas-filled switchgear, is a high-voltage switchgear that uses SF6 (sulfur hexafluoride) gas as the insulating medium. The main function of the gas tank filling valve is to fill the gas tank with an appropriate amount of gas to maintain the insulation performance and pressure stability in the gas tank.

[0003] The existing gas-insulated switchgear inflation valves have many parts, complex structures, inconvenient installation, and poor sealing performance, especially in complex outdoor environments, and cannot guarantee long-term sealing use.

[0004] After searching, the Chinese patent application number CN201821604070.8 discloses a simple inflation valve for opening and closing air boxes. The valve body uses air pressure to compress or relax the spring against the valve core to achieve the connection and blocking between the upper part of the valve body and the air box. By improving the material and surface treatment of the parts, the corrosion resistance of the inflation valve is effectively improved, and a double-layer sealing structure is added to improve the sealing performance of the inflation valve. In addition, it has fewer parts, a simple structure, easy installation, and cost saving.

[0005] When the above-mentioned simple inflation valve for switch gas box is actually used, additional tools or equipment are needed to assist the operation when the inflation valve is connected to the gas pipe, which increases the complexity of the operation. At the same time, gas is prone to leakage at the connection, affecting the insulation performance and operation stability of the inflation cabinet. Utility Model Content
