Embodiment Construction

[0021] An embodiment of the high-voltage switch cylinder of the present invention, hereinafter referred to as the cylinder, such as figure 1 As shown, one end of the cylinder body 11 has a sealing structure for sealingly mating with the adapter terminal fitting. The sealing structure includes a flange plate 12 arranged at the corresponding end of the cylinder body 11. The flange plate 12 is used for connecting with the terminal fitting. (It can be another high-voltage switch cylinder, or a cover plate) The side of the butt joint is the connection side, and the other side is the back side. There is a sealing ring groove 101 on the connecting side. When in use, the sealing ring groove can be A sealing ring is assembled in 101 to ensure the sealing of the fit between the cylinder body and the corresponding terminal fitting, thereby preventing gas leakage in the cylinder body. In addition, the flange 12 has a sealing portion at the outer edge of the connection side, The sealing pa...

Abstract

The invention relates to the field of high-voltage electric equipment, in particular to a high-voltage switch barrel and a high-voltage switch using the same. At least one end of the high-voltage switch barrel is provided with a sealing structure used for being in sealing matching with an adaptive end connecting member. The sealing structure comprises a flange plate arranged at a corresponding end of the barrel and a sealing ring arranged on the connecting side of the flange plate, a sealing part used for being in sealing matching with the adaptive end connecting member is arranged on the outer edge of the connecting side of the flange plate, a detecting channel is formed in the flange plate, the detecting channel is provided with a communication port located in the connecting side of the flange plate and a detecting port communicated with the communication port, the communication port is formed in the connecting side of the flange plate and located at the position between the sealing part and a sealing ring groove, and the detecting port is used for being matched with a corresponding leak test device and is sealed by a plug assembled in the leak test device. The high-voltage switch barrel and the high-voltage switch using the same solve the problems that when a current high-voltage switch barrel is used, leak tests consume time and labor, and sealing performance cannot be ensured.

Description

technical field [0001] The invention relates to the field of high-voltage electrical equipment, in particular to a high-voltage switch cylinder and a high-voltage switch using the high-voltage switch cylinder. Background technique [0002] The high-voltage switch cylinder is one of the most common parts in high-voltage switchgear. When it is used, it often needs to be connected to the corresponding terminal (another high-voltage switch cylinder or cover plate) through both ends, such as through two The two high-voltage switch cylinders are docked or one end is docked with another high-voltage switch cylinder, and the other end is sealed by the corresponding cover plate. However, no matter how it is connected to any part, it is necessary to strictly ensure that the high-voltage switch cylinder The sealing performance of the joint with the terminal fittings. At present, the sealing fit between the high-voltage switch cylinder and the terminal fittings is realized by the sealin...
