Embodiment Construction
[0021] An embodiment of the high-voltage switch barrel of the present invention, hereinafter referred to as the barrel, such as figure 1 As shown, one end of the cylinder 11 has a sealing structure for sealingly matching with the adapting terminal, and the sealing structure includes a flange 12 provided at the corresponding end of the cylinder 11, and the flange 12 is used to communicate with the terminal (It can be another high-voltage switch cylinder or a cover plate) The butt side is the connection side and the other side is the back side. The connection side is provided with a sealing ring groove 101. When in use, the sealing ring groove can be used A sealing ring is assembled in 101 to ensure the sealing of the fitting place between the cylinder and the corresponding terminal piece, thereby preventing gas leakage in the cylinder. In addition, the flange 12 has a sealing portion at the outer edge of the connection side, The sealing part is used to seal and cooperate with the...

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 cylinder. At least one end of the cylinder body of the high-voltage switch is provided with a sealing structure for sealingly cooperating with the adapter terminal. The outer edge of the connection side of the flange has a sealing part for sealing with the adapter, and a detection channel is provided in the flange, and the detection channel has a communication port on the connection side of the flange and is connected to the A detection port connected to the communication port. The communication port is located between the sealing part and the sealing ring groove on the connection side of the flange. The detection port is used to cooperate with the corresponding leak detection equipment and is sealed by the plug assembled therein; The invention solves the problems of time-consuming and labor-intensive leak detection and unguaranteed sealing performance existing in the current high-voltage switch cylinder during use.
Description
Technical field [0001] The invention relates to the field of high-voltage electrical equipment, in particular to a high-voltage switch barrel and a high-voltage switch using the high-voltage switch barrel. Background technique [0002] The high-voltage switch cylinder is one of the most common components in high-voltage switchgear. It often needs to be connected to the corresponding terminal (another high-voltage switch cylinder or cover plate) through both ends when in use, such as The two high-voltage switch cylinders are connected or connected to the other high-voltage switch cylinder through one end, and the other end is sealed by a corresponding cover plate. However, no matter how it is connected to any part, it is necessary to strictly ensure the high-voltage switch cylinder The sealing performance of the fitting place with the terminal fittings. At present, the sealing cooperation between the high-voltage switch cylinder and the terminal fittings is achieved by sealing rin...
