Abstract
Description
Technical Field
[0001] This utility model relates to the field of power supply cabinet technology, and more specifically to a relay protection test power supply cabinet. Background Technology
[0002] A relay protection test power supply cabinet, also known as a distribution box, is a component of a power supply system. It distributes electrical energy to various auxiliary circuits and provides fuses or circuit breakers for each circuit in the system. Typically, the main switch and the nearest distribution panel also include one or more residual current devices (RCDs) or residual current circuit breakers with overcurrent protection (RCB0).
[0003] Chinese utility model patent application CN202420341049.2 discloses a relay protection test power supply panel, including a cabinet. Casters for moving the cabinet are fixedly connected to the bottom of the cabinet, and a cover for positioning and protection of the cabinet is also fixedly connected to the bottom of the cabinet. A hydraulic tank for generating oil pressure is fixedly connected inside the cover, and a piston for pushing hydraulic oil is slidably connected inside the hydraulic tank. A self-locking component for pushing the piston is movably connected outside the hydraulic tank. While this increases the safety and reliability of the test power supply panel, it is inconvenient to repair the internal electrical components used for relay protection testing.
[0004] Therefore, it is necessary to propose a relay protection test power supply cabinet to solve the above problems. Utility Model Content

Mounting shafts are symmetrically fixedly connected to two corners at the end of the C-shaped cabinet away from the angle steel. Side plates are rotatably connected to the outer side of the mounting shaft. A front baffle is rotatably connected to one of the side plates away from the mounting shaft. The front baffle is locked to a lock body by a locking rod. The angle steel is located at a position where the side plate and the front baffle are rotated to 90°. The side plate is temporarily fixed to the angle steel by a locking mechanism.
[0008] Furthermore, the side plate has symmetrically provided mounting grooves at the end away from the mounting axis, and a mounting block is rotatably connected in the mounting groove. The mounting block is fixedly connected to one side of the front baffle.

[0010] Furthermore, the locking mechanism includes a limiting rod fixedly connected to the side of the side plate and a locking rod slidably connected to the limiting rod on the side away from the side plate. The slot allows the limiting rod to pass through, and the thickness of the limiting rod is the same as the thickness of the side plate.
[0011] Furthermore, a sliding groove is provided on the side of the limiting rod away from the side plate, and a sliding rod is slidably connected in the sliding groove, the sliding rod being fixedly connected to one side of the locking rod.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figure 1-5 A relay protection test power supply cabinet is disclosed. The application of relay protection test power supply cabinets in existing technologies is relatively mature. This application only improves the cabinet structure without modifying the connection method of the internal electronic components. The cabinet includes a C-shaped cabinet. Angle steel is symmetrically fixedly connected to the two corners of the ends of the C-shaped cabinet, with the right angle of the angle steel facing the center of the C-shaped cabinet. Mounting shafts are symmetrically fixedly connected to the two corners of the end of the C-shaped cabinet away from the angle steel. Side plates are rotatably connected to the outer side of the mounting shafts. One of the side plates is rotatably connected to a front baffle at the end away from the mounting shaft. The front baffle is locked to a lock body by a locking rod. The locking rod adopts a locking structure commonly used in existing cabinet technologies, which is relatively mature and will not be described in detail here. The angle steel is located at a position where the side plate and front baffle are rotated to 90°. The side plate is temporarily fixed to the angle steel by a locking mechanism. When the locking rod is locked, the inner sides of the side plate and front baffle are attached to the outer side of the angle steel.
[0024] Specifically, in combination Figure 1 and Figure 2 As shown, the side plate has symmetrical mounting grooves at one end away from the mounting axis, and a mounting block is rotatably connected in the mounting groove. The mounting block is fixedly connected to one side of the front baffle, thereby realizing the rotatable installation of the front baffle.
[0025] Specifically, in combination Figure 3 As shown, slots are symmetrically provided on the side of the angle steel.
[0026] Specifically, in combination Figure 4 and Figure 5 As shown, the locking mechanism includes a limiting rod fixedly connected to the side of the side plate and a locking rod slidably connected to the limiting rod on the side away from the side plate. The thickness of the limiting rod is the same as the thickness of the side plate. That is, when the side plate is attached to the angle steel, the limiting rod is just located in the slot. Then, the locking rod is pulled down to lock the side plate.
[0027] Specifically, in combination Figure 5 As shown, a groove is provided on the side of the limiting rod away from the side plate, and a sliding rod is slidably connected in the groove. The cross-section of both the groove and the sliding rod is T-shaped to prevent the sliding rod from sliding out of the groove. The sliding rod is fixedly connected to one side of the locking rod, thereby realizing the connection between the locking rod and the limiting rod.
[0028] When repairing the electronic components inside the relay protection test power supply cabinet, open the lock body, open the front panel, and then push the lock rod upwards so that the upper and lower ends of the lock rod are between the upper and lower ends of the slot. At this time, the side panel can be opened to repair the electronic components inside the cabinet.
[0029] The above are merely preferred embodiments of this utility model and are not intended to limit this utility model. The scope of patent protection of this utility model shall be determined by the claims. Similarly, any equivalent structural changes made based on the description and drawings of this utility model shall also be included within the scope of protection of this utility model.
