Embodiment 1

[0028] Such as figure 1 with figure 2 As shown in the figure, a safety label suitable for the secondary warehouse of the switch cabinet includes a magnetic suction cover 1 with a rectangular parallelepiped structure and a special label 2. One end face of the magnetic suction cover 1 is an open end face 1.1, and the other end faces are closed. , the opening end face 1.1 is provided with a leg 1.2 around it, the leg 1.2 is fixed with the magnetic suction type cover 1, and the first magnet 3 is fixed on the leg 1.2; the magnetic suction type cover 1 is provided with a second magnet 4 on the end face corresponding to the opening end face 1.1 , the second magnet 4 is fixed with the magnetic suction type cover 1, and the second magnet 4 is a T-shaped structure; the front side of the special signboard 2 is provided with a warning icon, and the back side of the special signboard 2 is provided with a magnetic metal plate 5, and the magnetic metal plate 5 and The special signboard 2 i...

Embodiment 2

[0031] On the basis of Embodiment 1, the support foot 1.2 is provided with a contact surface, and the contact surface is provided with a wave pattern protrusion; the side of the magnetic suction type cover 1 is provided with a handle, and one end of the handle is connected to the magnetic suction type hinged.

[0032] The contact surface is the surface where the legs 1.2 are in contact with the secondary compartment of the switch cabinet when the magnetic suction cover 1 is adsorbed on the secondary compartment of the switch cabinet. When the magnetic suction type cover 1 is adsorbed on the secondary compartment of the switch cabinet, the external force parallel to the surface of the switch cabinet secondary compartment will easily cause the magnetic suction type cover 1 to slip, which is not conducive to the fixing of the magnetic suction type cover 1 . The wavy protrusions can increase the friction force and increase the magnitude of the external force required to make the m...

Embodiment 3

[0034] Such as image 3As shown, on the basis of Embodiment 1, the support foot 1.2 is provided with a mounting hole 1.2.1, and the installation hole 1.2.1 is provided with an elastic friction block 6. The elastic friction block 6 is fixed to the support foot 1.2 and one end of the mounting hole 1.2 .1; the elastic friction block 6 is provided with a mounting groove 6.1, and the first magnet 3 is arranged in the mounting groove 6.1; the thickness of the first magnet 3 is less than the depth of the mounting groove 6.1; the center of the first magnet 3 is provided with a fixing hole 3.1, which is fixed A fixing bolt 9 is arranged in the hole 3.1, and one end of the fixing bolt 9 passes through the first magnet 3 and the elastic friction block 6 and is fixed with the supporting foot 1.2. When the first magnet 3 is close to the surface of the secondary warehouse of the switch cabinet, the first magnet 3 is in direct contact with the surface of the secondary warehouse of the switch...

Abstract

The invention discloses a safety signboard suitable for a secondary bin of a switch cabinet. The safety signboard comprises a special signboard; a warning icon is arranged on the front surface of thespecial signboard; the safety signboard further comprises a magnetic attraction type outer cover; an open end is arranged on the magnetic attraction type outer cover and is provided with a first magnet; a second magnet is arranged outside the magnetic attraction type outer cover opposite to the opening end; the first magnet is fixed to the magnetic attraction type outer cover; the second magnet isfixed to the magnetic attraction type outer cover; a magnetic metal plate is arranged on the back surface of the special signboard; the magnetic metal plate is fixed to the special signboard; and themagnetic metal plate is adsorbed on the magnetic attraction type outer cover through the second magnet. The safety signboard suitable for the secondary bin of the switch cabinet has the advantages ofbeing simple in structure, fast to mount, reliable and stable to fix, difficult to separate and the like; and a switch operation handle can be completely sealed in the magnetic attraction type outercover to prevent working personnel from touching the handle by mistake.

Description

technical field [0001] The invention relates to the technical field of operation and maintenance of substations, in particular to a safety signboard suitable for a secondary warehouse of a switchgear. Background technique [0002] As an important component of the power system, the armored switchgear is widely used in various substations, power plants, large enterprises and other places, and plays a vital role in industrial production and people's daily life. The equipment has achieved full coverage of 10kV, 20kV and 35kV voltage levels, and it can be said to be one of the most common equipment in the power grid. This type of equipment requires regular inspection and maintenance and irregular defect elimination work. However, due to the compact layout of the closed armored equipment, strict and standardized safety measures are required for each work to be carried out. However, due to the limitations of the traditional signboard itself, it is difficult to install it stably in...
