Description

Technical Field

[0001] This utility model relates to the field of electrical cabinet technology, and more specifically, to an incoming line cabinet. Background Technology

[0002] Incoming line cabinets are an important component of power systems. Currently, incoming line cabinets on the market consist of a cabinet body and a cabinet door. The rear of the cabinet body houses the busbar compartment. One side of the cabinet door forms a hinged end, and the other side forms a free end. The hinged end is rotatably connected to the cabinet body on one side of the busbar compartment via several hinges spaced from top to bottom. The free end is secured to the cabinet body on the other side of the busbar compartment via several screws spaced from top to bottom. The cabinet door is used to close the opening of the busbar compartment. In the above incoming line cabinet structure, because the free end of the cabinet door is secured to the cabinet body on the other side of the busbar compartment only by a few screws, non-professional maintenance personnel can easily remove the screws and allow the cabinet door to rotate and open relative to the cabinet body. Since the busbars in the busbar compartment carry high voltage, there is a significant risk of electric shock when non-professional maintenance personnel open the cabinet door. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide an incoming line cabinet that can effectively prevent non-professionals from accidentally opening the cabinet door, thereby effectively eliminating the risk of electric shock.

[0004] This utility model provides an incoming line cabinet, including a cabinet body and a cabinet door. A busbar compartment is provided on the rear side of the cabinet body. One side of the cabinet door forms a hinged end, and the other side of the cabinet door forms a free end. The hinged end is rotatably connected to the cabinet body located on one side of the busbar compartment by a number of hinges spaced from top to bottom. The free end is fastened to the cabinet body located on the other side of the busbar compartment by a number of screws spaced from top to bottom. The cabinet door is used to close the opening of the busbar compartment. A "U"-shaped latch is fixed on the inner side of the free end. A channel is provided on the cabinet body located on the other side of the busbar compartment for the latch to pass horizontally. An electromagnetic lock is fixed on the cabinet body located inside the channel. The electromagnetic lock is electrically connected to a controller in the incoming line cabinet. When the cabinet door is closed to the cabinet body so that the latch passes through the channel, the latch of the electromagnetic lock is used to insert into the latch to further lock the cabinet door and the cabinet body.

[0005] This utility model achieves two-stage anti-opening protection for cabinet doors and cabinet bodies through the combined action of an electromagnetic lock and a latch. After the free end of the cabinet door is secured to the cabinet body with several screws, the bolt of the electromagnetic lock can be inserted into the latch to further lock the cabinet door and cabinet body, thereby effectively preventing unauthorized personnel from accidentally opening the cabinet door and thus effectively eliminating the risk of electric shock.

[0006] In one possible implementation, the incoming line cabinet also includes an "L"-shaped bracket, one side of which is fastened to the cabinet body by a number of bolt assemblies spaced from top to bottom, and the electromagnetic lock is fastened to the other side of the bracket by a number of screws spaced circumferentially; with this structure, the electromagnetic lock can be reliably fixed to the cabinet body by the bracket.

[0007] In one possible implementation, reinforcing frames are vertically arranged on the inner side of both the hinge end and the free end. The upper and lower ends of each reinforcing frame abut against and are fastened to the inner top and bottom of the cabinet door, respectively. The outer side wall of each reinforcing frame is tightly attached to and fixed to the inner side wall of the cabinet door, and the front side wall of each reinforcing frame is tightly attached to and fixed to the front inner wall of the cabinet door. By providing reinforcing frames on the inner side of both the hinge end and the free end, the deformation resistance of the cabinet door can be improved, effectively preventing deformation of the cabinet door. Furthermore, since the upper and lower ends of each reinforcing frame abut against and are fastened to the inner top and bottom of the cabinet door, the outer side wall of each reinforcing frame is tightly attached to and fixed to the inner side wall of the cabinet door, and the front side wall of each reinforcing frame is tightly attached to and fixed to the front inner wall of the cabinet door, the reinforcing frames are securely fixed to the cabinet door, and provide good support for the cabinet door.

[0008] In one possible implementation, an observation window is provided in the middle of the cabinet door, and a grid-shaped observation hole is formed on the cabinet door inside the observation window; a glass plate corresponding to the observation window is fixed on the inside of the cabinet door; through the setting of the observation window and the observation hole, the inspection personnel can observe the condition inside the busbar room through the observation hole and the glass plate without opening the cabinet door, thereby facilitating the inspection of the incoming line cabinet by the inspection personnel.

[0009] In one possible implementation, two symmetrical clamping frames are fixed on the inner wall of the cabinet door. The two clamping frames are located on the upper and lower sides of the glass sheet, respectively. Each clamping frame has an "L"-shaped bending section on the side facing the glass sheet. Each bending section forms a groove with the cabinet door, and the upper and lower sides of the glass sheet are respectively inserted into the grooves at the corresponding positions. With this structure, under the action of the two clamping frames, and after the upper and lower sides of the glass sheet are respectively inserted into the grooves, the glass sheet can be reliably pressed against the inner wall of the cabinet door through the bending section, that is, the glass sheet can be reliably fastened to the cabinet door.

[0010] In one possible implementation, each clamping frame has folded edges at both ends, and each folded edge abuts against the corresponding end of the glass sheet. With this structure, under the action of the folded edges, after the clamping frame presses the glass sheet against the front inner wall of the cabinet door through the bending section, both ends of the glass sheet can abut against the folded edges, thereby achieving left and right limit of the glass sheet and further preventing the glass sheet from detaching from the cabinet door.
