Description

Technical Field

[0001] The utility model relates to the technical field of electrical air switch equipment, and particularly relates to a snap-type power-off warning sign for an electrical air switch. Background Art

[0002] The power-off maintenance of electrical secondary circuit equipment is an important link in the maintenance of power systems. It involves the inspection and maintenance of secondary circuits such as the protection, control, and monitoring of electrical equipment to ensure the safe and stable operation of power systems. When performing power-off maintenance on electrical secondary circuit equipment, a series of safety technical measures and standard operation procedures need to be followed. Before maintenance, it is necessary to ensure that the electrical equipment has been powered off and corresponding safety measures have been taken, such as pulling the switch and disconnecting the power supply, which is the basic premise for ensuring the safety of maintenance personnel. Subsequently, the appearance of the equipment can be inspected, carefully observing whether there are obvious damages, corrosion, deformations, etc. on the equipment, checking whether the wiring of the equipment is loose or has poor contact, and whether there are potential safety hazards in the surrounding environment of the equipment.

[0003] During the power-off maintenance process of electrical secondary circuit equipment, ensuring safety is of utmost importance. The current problem is that although traditional hanging warning signs can play a warning role, there is a risk of being accidentally knocked off by maintenance personnel during actual operation, and they may block the line of sight, affecting the inspection and maintenance of the wiring and other components below the air switch. In addition, in an environment with insufficient light, the risk of accidentally closing the air switch still exists, which may lead to safety accidents. Content of the Utility Model

[0004] Aiming at the problems of knocking off the warning sign and accidentally closing the air switch during the maintenance of electrical secondary circuit equipment;

[0005] The utility model provides a snap-type power-off warning sign for an electrical air switch, which includes a warning sign and a snap. The upper end of the warning sign is connected to the snap. One or more through holes are opened at the top of the warning sign, and a connecting rope is arranged in the through holes to connect to a lock block clamped in the locking hole at the handle.

[0006] As a preferred solution, a hanging ring is arranged at the top of the warning sign. The snap is in a dovetail shape, including a hanging section, a connecting section, and a clamping section that are symmetrically arranged and fixedly connected in sequence to form a Z shape symmetrical on both sides. The hanging section passes through the hanging ring, and the clamping section is clamped on the side wall of the locking hole.

[0007] As a preferred solution, lock pieces are symmetrically and fixedly arranged on the side surface of the lock block.

[0008] Furthermore, the lock piece is made of an elastic material, and one end is fixedly connected to the lock block and has an inclination angle with the lock block.

[0009] Furthermore, a depression for clamping the side wall of the locking hole is arranged in the middle of the lock piece.

[0010] As a preferred solution, the included angle between the hanging section and the connecting section is 45 degrees to 90 degrees.

[0011] As a preferred solution, the included angle between the clamping section and the connecting section is 45 degrees to 90 degrees.

[0012] As a preferred solution, the inclination angle is 15 to 45 degrees.

[0013] As a preferred solution, the size of the lock block is adapted to the size of the locking hole.

[0014] The beneficial effects of the present utility model are as follows:

[0015] The present utility model can not only play a warning role, but also fundamentally prevent the accidental closing of the air switch by setting the lock block. In addition, the warning sign is not easily knocked off during the maintenance process, and the warning sign can also be turned upwards during the maintenance of the electrical components at the lower outlet of the air switch, making the maintenance work more convenient.
