Description

Technical Field

[0001] The utility model belongs to the technical field of high-voltage switch equipment, and in particular relates to an auxiliary tooling for assembling a hydraulic operating mechanism of a high-voltage switch. Background Art

[0002] The operating mechanism of high-voltage switchgear is large in size and heavy in weight, which makes assembly difficult. Especially for switchgear with the operating mechanism located under the shell, the mechanism cannot be hoisted during assembly and needs to be assembled with the help of special tooling. Currently, the main method is to support the operating mechanism by configuring a V-shaped support tooling at a specified height under the mechanism before assembly. Typical high-voltage switchgear such as Figure 1 As shown, the switchgear body 01 is a horizontal double-break structure, with the breaks on the left and right sides completely symmetrical, sharing a transmission system, which is connected to the hydraulic operating mechanism 03 through the transmission parts in the mechanism box 02. The hydraulic mechanism outputs operating force to drive the transmission system to drive the breaks on both sides to achieve the opening or closing of the switchgear body. When assembling the switchgear, first assemble the switchgear body 01, then assemble the mechanism box 02 and the hydraulic operating mechanism 03 into components, and hoist them onto the V-shaped support fixture 04 to adjust the assembly size, hoist the switchgear body 01 and place it on the component, and connect the hydraulic operating mechanism 03 and the mechanism box 02 with the switchgear body 01.

[0003] For different types of switch products and operating mechanisms, V-shaped support fixtures 04 of different specifications need to be designed, resulting in a wide variety of fixtures, lack of versatility, and inconvenience in management and use. Utility Model Content
