Description

Technical Field

[0001] The utility model relates to the technical field of isolating switches, and more specifically, to an anti-misoperation device for isolating switches. Background Art

[0002] An isolating switch is a switching device that is mainly used for "isolating power supply, switching operation, connecting and disconnecting small current circuits" and has no arc extinguishing function. When the isolating switch is in the disconnect position, there is an insulation distance that meets the specified requirements and an obvious disconnection mark between the contacts. In order to prevent workers from misoperating the isolating switch, workers are usually required to pay special attention when operating it. For example, a misoperation prevention device for an isolating switch described in the prior art publication number (CN217902992U) drives the baffle to move forward on the surface of a mounting shell on one side. When the push blocks on the upper and lower sides of the baffle touch the limit blocks, the limit blocks will move to one side to allow the baffle to continue moving. When the baffle moves to the frontmost side, the limit block will rebound through the second spring to block the push block on one side, so that the baffle cannot move backward and obtain a limiting effect. At this time, the switch on the surface of the switch body can be started. After the operation is completed, push the push plates on the upper and lower sides with both hands.

[0003] When the above device is in use, it can protect the isolating switch to prevent irrelevant personnel or other factors from accidentally touching the isolating switch, thereby avoiding the start-up or shutdown of the isolating switch due to accidental touching, and further reducing the safety hazards caused by accidental touching of the isolating switch. However, its structure is relatively complex and prone to failure, which affects the stability of its operation. Utility Model Content
