[0023] Please see Figure 1-4 The present invention provides the following technical solution:
[0024] A modular high-voltage switch housing includes a main housing 1, which is a cylindrical structure with openings on both sides. A bracket 2 is fixed on one side of the cylindrical wall of the main housing 1, and three connection ports 4 are provided on the other side of the cylindrical wall of the main housing 1. Movable covers 3 can be sealed to the openings on both sides of the main housing 1, and movable covers 5 can be sealed to the openings of the connection ports 4. The openings on both sides of the main housing 1 and the three connection ports 4 cover the selection of most high-voltage switch connection methods. Unnecessary openings can be easily covered according to usage requirements, thereby improving the applicability of the housing and facilitating inventory preparation.
[0025] The second movable cover 5 includes a cover plate 51. A flange is provided on the side of the connection port 4 that is connected to the second movable cover 5. A corresponding flange is provided on the cover plate 51. The cover plate 51 is connected to the flange of the connection port 4. A flange is provided on the opening of the first movable cover 3 and the main housing 1. The flange of the first movable cover 3 is connected to the flange of the main housing 1.
[0026] The flanges of movable cover 1 (3) and main housing 1, as well as the flanges of movable cover 2 (5) and connection port 4, are all connected and fixed by clamps (6), reducing the use of bolts without affecting the sealing effect.
[0027] A connecting rod 52 is connected to the side of the cover plate 51 facing the main housing 1. The connecting rod 52 extends towards the main housing 1, and a plug 53 is connected to the end of the connecting rod 52. The plug 53 can abut against the opening of the main housing 1 at the connection port 4. A sealing ring 55 is provided on the side wall of the plug 53. The sealing ring 55 seals the opening of the main housing 1 at the connection port 4, so that no gas leakage will occur at the plug 53. The plug 53 fills the gap of the main housing 1 at the connection port 4 that is not used, which facilitates the detection of free electrons in the housing. That is, while flexibly selecting the opening, the overall sealing and detection function can be guaranteed.
[0028] The clamp 6 includes two semi-circular clamps 61, which are connected by bolts. Grooves 54 are provided on the side of the flange opposite to the flange of the main housing 1, movable cover 1 3, connection port 4 and movable cover 2 5. Pressure rings 62 are provided on both sides of the semi-circular clamps 61. The two pressure rings 62 can abut against the sides of the corresponding two flanges respectively. A convex ring 63 is provided on the pressure ring 62, and the convex ring 63 abuts against the groove 54. A sealing ring 2 7 is provided between the abutting end faces of the corresponding two flanges. The clamp 6 and the sealing ring 2 7 can ensure the sealing effect at the opening connection.
[0029] Specifically, the main housing 1 has openings on both sides, and three connection ports 4 are provided on the tube wall of the main housing 1. The openings of the main housing 1 can be sealed by the movable cover 3, and the openings of the connection ports 4 can be sealed by the movable cover 5. The unnecessary openings can be closed selectively according to the usage requirements, thereby improving the applicability of the housing. The movable cover 5 is provided with a plug 53 to fill the inner wall of the main housing 1 at this point, thereby facilitating the automatic detection equipment to measure the free electrons inside the housing, thus improving applicability while ensuring its own function.
