DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] This gas-insulated switchgear with good arc extinguishing effect provides two technical solutions:

[0026] like Figure 1-3 The first embodiment is shown: it includes a support frame 1 and a gas-insulated switchgear body 2 fixed thereon, and a quick disassembly mechanism is provided on the right side of the gas-insulated switchgear body 2, and the quick disassembly mechanism includes:

[0027] The lock catch assembly 3 comprises four groups of U-shaped rotating parts 31, which are fixed at equal distances on the circumference of the opening of the gas-insulated combination electrical appliance body 2, and the four groups of U-shaped rotating parts 31 are rotatably connected to the inside of the four groups of U-shaped rotating parts 31, and the surface of the gas-insulated combination electrical appliance body 2 is rotatably connected to a rotating ring 33, and four top blocks 34 are fixedly connected to the annular surface of the rotating ring 33 at equal distances, and a hand lever 35 is also fixedly connected to the annular surface of the lock catch assembly 3, and the positions of the four top blocks 34 correspond to the positions of the four buckle rods 32, and the shape of the four top blocks 34 is a plate-like object with a gradually increasing height on one side;

[0028] The positioning assembly 4 is arranged on the rotating ring 33 and is used to position the rotating ring 33 after rotation. The positioning assembly 4 includes a slide block 41, which is fixedly connected to the left side of the rotating ring 33. The inner surface of the slide block 41 is slidably connected to a limit block 42, and the limit block 42 extends to the outside of the slide block 41. The return spring 43 is fixedly connected between the limit block 42 and the inner wall of the return spring 43. A positioning block 44 is fixedly connected to the surface of the gas-insulated combination electrical appliance body 2, and one side of the limit block 42 is beveled with an inclined surface for cooperating with the positioning block 44.

[0029] The end cover 51 is pressed and locked by the locking assembly 3 at the port of the gas-insulated combination electrical appliance body 2. When disassembling, there is no need to unscrew a large number of bolts, and only the rotating ring 33 needs to be rotated, which greatly improves the practicality of the device when in use.

[0030] like Figure 4 The second embodiment is shown, which mainly differs from the first embodiment in that: a sealing assembly 5 is used to cooperate with the locking assembly 3 to seal the opening of the gas-insulated combination electrical appliance body 2, and the sealing assembly 5 includes an end cover 51, an extension tube 52 is fixedly connected to the left side of the end cover 51, a circular ring 53 is slidably connected to the surface of the extension tube 52, and a sealing ring is arranged on the left side of the circular ring 53, a limit spring 54 is fixedly connected to the side of the circular ring 53 opposite to the end cover 51, and the limit spring 54 is sleeved on the outside of the extension tube 52, and a circular groove 55 adapted to the extension tube 52 is provided at the right opening of the gas-insulated combination electrical appliance body 2.

[0031] A sealing assembly 5 is provided on the end cover, so that after the locking assembly 3 presses the end cover 51, the overall sealing can be ensured, thereby avoiding leakage of the internal inert gas and ensuring the arc extinguishing effect.

[0032] When in use, align the extension tube 52 on the end cover 51 with the annular groove 55 and insert it. After insertion, rotate the rotating ring 33 to make the top block 34 contact with the buckle rod 32. As the rotating ring 33 rotates, one side of the buckle rod 32 is pushed up, so that the other side of the buckle rod 32 is buckled to the right side of the end cover 51, so that the end cover 51 is pressed tightly against the opening on the right side of the gas-insulated combination electrical appliance body 2. The rotating ring 33 rotates while driving the limit block 42 to rotate. After the limit block 42 rotates to contact with the positioning block 44, The limit block 42 is moved upward by the action of the inclined surface, and after the limit block 42 passes over the positioning block 44, the limit block 42 is reset by the action of the reset spring 43, thereby positioning. In addition, after the buckle rod 32 presses the end cover 51, the sealing ring on the circular ring 53 is pressed against the end face of the circular groove 55 by the action of the limit spring 54, thereby ensuring the seal. When disassembling, the limit block 42 is pushed to move upward, and the rotating ring 33 is rotated in the opposite direction to release the buckle rod 32 from fastening the end cover 51.
