Description

Technical Field

[0001] The utility model relates to the technical field of high-voltage isolating switches, in particular to an anti-tripping structure of a high-voltage isolating switch. Background Art

[0002] A high-voltage isolating switch is a common electrical appliance that acts as an isolator in a circuit. A high-voltage isolating switch is a type of isolating switch. Existing high-voltage isolating switches generally include a moving end insulating support and a static end insulating support fixed to a base, a moving touch plate and a static touch plate are fixed to the moving end insulating support and the static end insulating support, respectively, a group of spaced isolating contact pieces are rotatably mounted on the static touch plate end through a corresponding mounting seat, and the two ends of the spaced isolating contact pieces are detachably snapped onto the static touch plate and the moving touch plate, respectively.

[0003] After searching, the Chinese patent publication number CN215680458U discloses an anti-drop mechanism for a single-piece high-voltage disconnector, which mainly uses a limiting torsion spring to make the anti-drop fastener movably clamped into the card interface on the connecting plate, and the anti-drop fastener is connected to the card hook on the hanging buckle plate, thereby preventing the high-voltage disconnector from dropping out.

[0004] By comparing the existing technologies in related fields, it can be seen that the existing anti-unhooking mechanism mainly relies on the elastic force of the spring to drive the limit rod to limit the dynamic and static touch plates. Since the elasticity of the spring has a certain limit, the dynamic and static touch plates cannot be effectively limited, the anti-unhooking performance is poor, and the stability of the connection between the dynamic and static touch plates is poor.
