Description

Technical Field

[0001] This utility model relates to the field of outdoor disconnect switch technology, specifically a flip-type outdoor disconnect switch. Background Technology

[0002] A flip-type outdoor disconnect switch is a mechanical switching device with a clear disconnect point used in power systems. It is mainly used to isolate circuits, ensure maintenance safety, or switch lines. Its core feature is that it achieves opening and closing operations by rotating or flipping the moving contact. It is suitable for outdoor environments and must have properties such as dustproof, rainproof, and corrosion-resistant properties.

[0003] For example, the flip-type disconnector spring device disclosed in the authorization announcement number CN215933464U includes a first frame, the first frame is connected to an anti-static workbench for support, the first frame is connected to a support plate and a third frame on the outside of the anti-static workbench, the top of the support plate is connected to a limiting structure for limiting the flip-type disconnector, and the third frame is connected to a spring structure for the flip-type disconnector spring; Although it can be placed on an anti-static workbench, the supporting straight plate, angle steel limiting plate and top limiting plate of the limiting structure limit the rear side wall, left side wall and top of the flip-type disconnect switch, so that the spring is set to face the push column. The compression spring structure drives the supporting horizontal plate to move the push column, and the push column drives the tension spring ring limiting groove to move, so that the spring is locked in the tension spring ring limiting groove. The push column is pushed to the assembly position through the tension spring ring limiting groove, and the spring retaining shaft is inserted into the flip-type disconnect switch. The spring retaining shaft is then fixed to realize the spring installation. The spring compression device of the flip-type disconnect switch can be easily installed by a single person, reducing labor intensity. At the same time, it ensures installation safety and avoids personnel injury caused by spring falling off. However, this does not solve the problem that existing outdoor disconnect switches generally do not allow for easy switching to close and energize, nor do they facilitate simultaneous contact of two sets of wiring devices. This affects the efficiency of the outdoor disconnect switch, hinders convenient replacement of the contact devices, and may lead to damage over time. This severely impacts the ease of use and safety of outdoor disconnect switches, causing significant inconvenience for users. Utility Model Content
