Technical Field
[0001] The utility model relates to the technical field of electric power equipment, in particular to a high-voltage construction grounding interlocking guide safety device. Background Art
[0002] Grounding interlock is a safety mechanism that is mainly used to ensure that when a specific part of an electrical device or system is inspected or maintained, the relevant part has been safely grounded to avoid electric shock or other electrical hazards. The main purpose of grounding interlock is to ensure the safety of operation and prevent misoperation. It ensures that certain parts of the equipment cannot be operated or accessed under certain circumstances by physical or electrical means, thereby protecting the safety of operators.
[0003] When the grounding interlock is in use, the static contact and the moving contact are in frequent contact. Due to the large kinetic energy during contact, wear occurs between the static contact and the moving contact, resulting in the inability of the static contact and the moving contact to fit closely, thus affecting the safety of the circuit breaker.

[0010] Preferably, a top ball is fixedly connected to the side of the top plate facing the mounting frame.
[0011] Compared with the prior art, the beneficial effects of the utility model are:
[0012] 1. The utility model cooperates with the use of a rotating shaft, a static contact module, a moving contact module, a buffer sheet, a sliding block, and a first sliding rod. The rotating shaft drives the moving contact module to contact the static contact module to achieve grounding. When the moving contact module contacts the static contact module, the buffer sheet contacts the buffer sheet, and the buffer sheet drives the sliding blocks on both sides to move along the first sliding rod. The first spring plays a buffering role on the power, which can avoid frequent contact between the static contact and the moving contact, causing wear at the fitting place, resulting in failure to fit smoothly, thereby affecting the service life of the grounding interlock.
[0013] 2. The utility model also uses the sliding block, the second spring, the fixing sheet, the locking rod, the locking hole, the first spring, the static contact module, the moving contact module, the top sheet, the third spring, and the top ball. When the sliding block rises to a certain height, the second spring pulls the fixing sheet to insert the locking rod into the locking hole to prevent the potential energy accumulated by the first spring from causing the moving contact module to separate from the static contact module through the buffer sheet. When the moving contact module separates from the static contact module, it drives the top sheet to move along the outside of the mounting frame. The third spring pushes the top sheet to make it close to the mounting frame. The top sheet cooperates with the top ball to push the boss to make the locking rod separate from the locking hole, so that the buffer sheet can fall back to its original position, which can ensure that the buffer device does not affect the connection between the static contact and the moving contact, and can return to its original position when disconnected.
