Problems solved by technology
[0004] However, the following problems may also occur during the use of the above scheme: when the drawer unit moves inside the switchgear, the moving direction of the drawer unit is not restricted, so that the drawer unit is prone to swing when it moves, and at the same time If the drawer unit collides with the inner wall of the cabinet when it swings, the impact generated by the collision will be transmitted to the inside of the drawer unit, which will easily cause damage to the electrical components inside the drawer unit, making the electrical components inside the drawer unit unable to work normally

Embodiment Construction
[0029] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0030] refer to Figure 1-4 The shown intelligent low-voltage withdrawable switchgear includes a switchgear body 1, a drawer 2 and an installation cavity 3. The installation cavity 3 is opened inside the switchgear body 1, and the drawer 2 is slidably installed inside the installation cavity 3. , the two sides of the drawer 2 are respectively provided with guide grooves 4, the two sides of the inner wall of the installation cavity 3 a...

The invention discloses an intelligent low-voltage withdrawable switchgear, which relates to the technical field of withdrawable switchgear, and comprises a switchgear body, a drawer and an installation cavity. The installation cavity is set inside the switchgear body, and the drawer is slidably installed in the installation cavity. Inside the body, guide grooves are provided on both sides of the drawer, sliding extrusion components are installed on both sides of the inner wall of the installation cavity, and locking components are installed at the connection between the drawer and the installation cavity and the inside of the switch cabinet body. One side of the stop assembly abuts against the bottom of the drawer. In the above solution, the sliding block moves along the surface of the guide rail along the surface of the guide rail with the dragging of the handle, the drawer, and the guide groove to the side close to the damper outside the inner cavity of the installation cavity, and the position of the sliding block is limited to effectively prevent the drawer and the installation cavity from colliding. The collision causes damage to the electrical components inside the drawer, so that the electrical components inside the drawer cannot perform normal operations. Based on this scheme, the linkage between the structures is strong and the use cost is low.
Description
technical field [0001] The invention relates to the technical field of withdrawable switch cabinets, in particular to an intelligent low-voltage withdrawable switch cabinet. Background technique [0002] Low-voltage switchgear is suitable for power plants, petroleum, chemical, metallurgy, textile, high-rise buildings and other industries, as power transmission, distribution and power conversion. The switch cabinet is a kind of electrical equipment. The outside line first enters the main control switch in the cabinet, and then enters the sub-control switch. Each branch is set according to its needs. The switch cabinet has the advantages of high breaking capacity, good dynamic and thermal stability, safety and reliability. [0003] After searching, Chinese patent CN210577361U discloses a draw-out low-voltage switch cabinet that can prevent the drawer from shaking, including a cabinet frame, a partition board, a mounting bracket and a drawer unit. Therefore, shaking of the dr...
