Description

Technical Field

[0001] The utility model relates to the technical field of switch cabinet protection, in particular to a high-voltage switch cabinet safety protection mechanism. Background Art

[0002] High-voltage switchgear is a device used to control and protect high-voltage electrical equipment. It is usually used in power systems to control and distribute high-voltage electrical energy, while providing protection and safety measures to ensure the stable operation of the power system. High-voltage switchgear can be used to control the switching operation of high-voltage power systems. It can open, close, connect or isolate circuits to achieve control and management of power systems. High-voltage switchgear is an important equipment in power systems. In order to ensure safe operation, it is usually equipped with a variety of safety protection mechanisms.

[0003] A Chinese patent document with a search announcement number of CN219627149U discloses a high-voltage switch cabinet with a protective function, including a high-voltage switch cabinet, a slide rail, two sliders and a switch module, the two sliders are located in the inner cavity of the high-voltage switch cabinet, the slide rail is located on the top of the two sliders, the switch module is located on the top of the slide rail, and the left and right sides of the bottom of the switch module are fixedly connected with plug-in rods, the surface of the plug-in rods is in contact with the inner cavity of the slide rail, and the inner cavity of the slide rail is provided with a placement groove. By setting up the coordinated use of high-voltage switch cabinet, slide rails, sliders, switch modules, plug-in rods, placement slots, positioning mechanisms and transmission mechanisms, the problem that the existing slide rails have no function of limiting the switch modules is solved. In this way, the switch modules may be easily dislocated due to external forces, resulting in problems such as falling and damage, making it inconvenient for users to stably pull out the switch modules for use through the coordination of the slide rails and sliders. When the high-voltage switch cabinet is in use, it cannot dissipate the heat of the electrical components inside the switch cabinet, because the components inside the switch cabinet will generate a lot of heat when the switch cabinet is working. If the heat is not dissipated, the temperature inside the switch cabinet will increase, thereby affecting the performance and life of the electrical components and reducing the protective effect of the high-voltage switch cabinet.
