Problems solved by technology
[0002] In the field of electric power technology, high-voltage switchgears often need to be overhauled, maintained and modified. Because most of the existing high-voltage switchgears, the switch opening and closing gates are exposed on the cabinet door, especially when the operator enters the switchgear During operation, when the switch opening and closing gate is touched by mistake, an electric shock accident will occur

Embodiment Construction
[0021] The preferred modes of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0022] see figure 1 , a switch protection device for a high-voltage switch cabinet, which is arranged on the cabinet door 100 of the high-voltage switch cabinet, and includes a square protective frame 20, which is enclosed within the protective frame 20 to protect the switch 40 disposed inside it. For the protection area 10 that is accidentally touched, the sliding door 80 is limited by the chute mechanism and the protection area 10 is opened or closed by the opening and closing adjustment mechanism, so that the switch 40 is sealed in the protection area 10 when it is not operated.
[0023] In the switch protection device for the high-voltage switchgear, one side of the protection frame 20 is provided with an opening 70 for the sliding door 80 to pass through, and the sliding door 80 enters or leaves the protection area 10 through the o...

The invention relates to a switch protection device of a high-tension switch cabinet, and relates to the technical field of electric power. The switch protection device is arranged on a cabinet door of the high-tension switch cabinet. The switch protection device comprises a square protective frame; a protective area for protecting a switch arranged inside the protective frame from being accidentally touched is encircled and formed inside the protective frame; and a sliding type movable door realizes that the protective area is opened or closed through a sliding groove mechanism, so that the switch is enclosed inside the protective area when being not operated. An opening for the sliding type movable door to pass through is formed in one side of the protective frame, and the sliding type movable door enters into or leaves away from the protective area from the opening. According to the switch protection device, the switch is enclosed through the protective area, when the protective area does not need to be opened, the protective area is enclosed through the sliding type movable door, and the switch is not accidentally touched, so that the operational safety of the high-tension switch cabinet is greatly improved. The switch protection device is high in integral sealing performance, and the function failure of the protective device due to the influence of terrible conditions cannot be caused. The switch protection device is relatively convenient in operation and long in integral service life, and the moving damping value of the sliding type movable door is moderate.
Description
technical field [0001] The invention relates to the field of electric power technology, in particular to a switch protection device for a high-voltage switch cabinet. Background technique [0002] In the field of electric power technology, high-voltage switchgears often need to be overhauled, maintained and modified. Because most of the existing high-voltage switchgears, the switch opening and closing gates are exposed on the cabinet door, especially when the operator enters the switchgear During operation, when the switch opening and closing gate is accidentally touched, an electric shock accident will occur. Therefore, it is necessary to design a switch protection device to avoid this phenomenon. Contents of the invention [0003] The purpose of the present invention is to provide a switch protection device for a high-voltage switchgear, which can protect the switch to avoid accidental touch, and it has the characteristics of high safety performance. To achieve the abo...
