Description

Technical Field

[0001] The utility model relates to the technical field of test power supply screens, in particular to a test power supply screen with a protection structure. Background Art

[0002] The relay protection test power supply panel is suitable for power plants, substations and large and medium-sized industrial enterprises. It can be used as a standard relay protection test power supply. It adopts dual power supply, which can be switched manually or automatically. It can be switched with load using contactors to ensure the reliability of power supply. The AC power supply adopts a large-capacity isolation transformer to isolate the system power supply from the test power supply, and install a shielding layer between the primary and secondary to protect the test power supply from transient grid processes and other harmonic interference. The structure of the existing test power supply panel is relatively fragile and is easily damaged by bumps during frequent use.

[0003] Comparative document CN212696325U discloses a test power supply screen with a protective structure, in which the docking protrusion at one end of the wrapping layer is inserted into the docking groove to complete the combined splicing of the wrapping layer and the frame. After the wrapping layer and the frame completely wrap the outer side of the joint frame, the protective pad protects the side of the joint frame, and the wrapping layer protects the corners of the joint frame. When the corners of the wrapping layer are collided, the second spring is compressed to reduce the impact force. However, the above-mentioned device only protects the corners of the power supply screen, and the front surface of the power supply screen fails to provide protection and is easily damaged. In addition, the power supply screen is easily shaken during use by using the spring to affect its use. Utility Model Content

Since the limiting strip 402 is inserted into the inside of the frame 101, the power screen body 7 can be prevented from shaking during normal use and affecting use.

[0030] Working principle: limit the power screen body 7 inside the protection frame 1, and then insert the clamping rod 203 at the bottom of the top plate 201 into the clamping hole 204 on the frame 101. When the clamping rod 203 moves down, it compresses the reset spring connected to the protrusion 5 until the protrusion 5 moves into the groove 6. The reset spring resets and clamps the protrusion 5 into the groove 6, thereby clamping and fixing the clamping rod 203 inside the clamping hole 204. The top cover 2 is used to provide protection for the top of the power screen body 7. The transparent cover 301 rotates on the outside of the frame 101 to facilitate observation of the power screen body. 7, and it is convenient to open and operate the power screen body 7. The transparent cover body 301 is clamped in the limiting groove 304 through the limiting rod 302 and fixed to the outside of the frame 101. When the frame 101 is vibrated, it contacts the protection block 401. The protection block 401 drives the limiting strip 402 to slide inside the frame 101 and compresses the spring 403. The spring 403 is deformed to achieve the purpose of buffering. Since the limiting strip 402 is plugged into the inside of the frame 101, the power screen body 7 can be prevented from shaking during normal use and affecting use.
