Description

TECHNICAL FIELD

[0001] The application belongs to the field of high-voltage electrical apparatus, and particularly relates to a high-voltage load switch precise stop plate. BACKGROUND

[0002] In a high-voltage load switch, the stop plate not only plays a key role in supporting the cylinder, but also indirectly participates in the arc extinguishing process of the switch. When the switch operates, the cylinder releases high-pressure gas to quickly extinguish the electric arc, and this process is accompanied by strong impact force and vibration. Due to the insufficient stability of the structure or the insufficient strength of the material, the traditional stop plate design is difficult to withstand such frequent and strong impact for a long time, and is prone to looseness, position deviation or wear of the stop plate, thereby affecting the precise operation and stable operation of the switch. In addition, the inaccuracy of the stop plate may also cause inaccurate positioning of the cylinder, affecting the release effect of the gas and the arc extinguishing efficiency. Therefore, it is necessary to solve the above technical problems. CONTENT OF THE UTILITY MODEL

[0006] A connecting table is connected to the annular side wall and forms a threaded hole axially parallel to the mounting hole;

[0007] A plug-in foot is arranged inside the annular side wall and connected to the top wall, and the side of the plug-in foot away from the top wall is flush with the side of the connecting table away from the annular side wall.

[0008] Optionally, the connecting table and the plug-in foot are arranged symmetrically about the center axis of the annular side wall and distributed on opposite sides of the center of the mounting hole.

[0009] Optionally, the high-voltage load switch precise stop plate further comprises four supporting legs connected to the top wall;

[0010] The supporting legs are arranged inside the annular side wall and arranged symmetrically about the center of the mounting hole.

[0011] Optionally, the high-voltage load switch precise stop plate further comprises a reinforcing table connected to the supporting legs.

[0012] The reinforcing platform is also connected to the top wall, and a side of the reinforcing platform away from the top wall is closer to the top wall than a side of the leg away from the top wall.

[0013] Optionally, the high-voltage load switch precision stop plate further comprises reinforcing ribs connected between adjacent connecting platforms.

[0014] The side of the reinforcing rib close to the mounting hole forms an arc shape coaxial with the annular side wall.

[0015] Optionally, the high-voltage load switch precision stop plate further comprises a plurality of reinforcing rib plates connected to the top wall.
