It can complete tests on relay characteristics, relay protection, microcomputer protection, electrical secondary control circuits, automatic devices, etc. in power supply and distribution systems of power plants, substations and factories. The test bench has a simple structure and powerful and practical comprehensive performance. However, when in use, when the relay protection test bench is moved, it needs to be carried by multiple people, which increases the difficulty of transfer and increases the transfer cost, further affecting the transfer efficiency.

[0004] Therefore, a comprehensive test bench for relay protection of power system is proposed. Utility Model Content

[0005] The utility model aims to provide a comprehensive test bench for relay protection of an electric power system.

[0013] Preferably, one end of the threaded screw away from the threaded hole is fixedly connected to a rotating disk, and the inner side of the rotating disk is made of rubber material.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. By setting up a sliding component, when the staff needs to transfer the main body of the laboratory bench, the electric telescopic rod is started at this time. The extension of the electric telescopic rod can drive the support plate in the movable groove to slide down along the slide rail. When the universal wheel at the bottom end of the support plate contacts the ground, the main body of the laboratory bench is pushed to cooperate with the universal wheel to move the main body of the laboratory bench, which is convenient and fast to transfer the main body of the laboratory bench, and can avoid manual transportation, improve transportation efficiency, and save labor costs. When the transportation is completed, the electric telescopic rod is controlled to retract. At this time, the support plate can drive the universal wheel to retract into the movable groove, so that the main body of the laboratory bench can be in contact with the ground as a whole, which can improve the stability of the main body of the laboratory bench and is conducive to the use of the main body of the laboratory bench.

[0016] 2. By setting up a fastening component, when the support plate pushes the universal wheel to contact the ground, the staff rotates the rotating disk clockwise, and the rotating disk can drive the threaded screw to rotate. At this time, the threaded screw can be continuously embedded in the threaded hole. When the inner side of the rotating disk is tightly fitted with the main body of the laboratory table, since the inner side of the rotating disk is made of rubber material, the friction between the rotating disk and the main body of the laboratory table increases. The support plate can be fixed by the rotating disk, which can reduce the load during the support process of the electric telescopic rod, which is conducive to the long-term use of the electric telescopic rod.

An electric telescopic rod 13 is also fixedly installed on the top of the movable slot 9, and the extended end of the electric telescopic rod 13 is fixedly connected to the top wall of the support plate 11.

[0026] See also Figure 3 , a plurality of slide grooves 14 are symmetrically provided on both side walls of the support plate 11, and the slide grooves 14 are adapted to the slide rails 12.

[0027] See also Figure 2 A wiring socket 4 is fixedly installed at the bottom of the test panel 6. A signal light 5 is also provided on the test panel 6 and above the wiring socket 4, and the signal light 5 is electrically connected to the wiring socket 4.

[0028] See also Figure 2 , a plurality of instrument panels 7 and display screens 8 are also provided on the top of the test panel 6, and the instrument panels 7 and display screens 8 are electrically connected to the wiring sockets 4 respectively.

[0029] In this embodiment, during use, when the staff needs to transfer the laboratory table main body 1, the electric telescopic rod 13 is started at this time. The extension of the electric telescopic rod 13 can drive the support plate 11 in the movable groove 9 to slide downward along the slide rail 12. When the universal wheel 15 at the bottom end of the support plate 11 contacts the ground, the laboratory table main body 1 is pushed to cooperate with the universal wheel 15 to move the laboratory table main body 1, which is convenient and fast to transfer the laboratory table main body 1, can avoid manual transportation, can improve transportation efficiency, and can save labor costs. When the transportation is completed, the electric telescopic rod 13 is controlled to retract. At this time, the support plate 11 can drive the universal wheel 15 to retract into the movable groove 9, which can make the laboratory table main body 1 as a whole contact with the ground, can improve the stability of the laboratory table main body 1, and is conducive to the use of the laboratory table main body 1.

[0030] Example 2:

[0031] See also Figures 1 to 4 A comprehensive test bench for relay protection of an electric power system also includes: a fastening assembly arranged at the bottom end of the test bench body 1, the fastening assembly includes a threaded hole 17 opened on the side wall of the support plate 11, and a threaded screw 18 is spirally installed in the threaded hole 17.

[0032] See also Figure 4 An open slot 10 communicating with the movable slot 9 is also provided on the side wall of the laboratory table body 1, and one end of the threaded screw 18 away from the threaded hole 17 extends to the outside of the open slot 10.

[0033] See also Figure 4 One end of the threaded screw 18 away from the threaded hole 17 is fixedly connected to the rotating disk 16, and the inner side of the rotating disk 16 is made of rubber material.

At this time, the threaded screw 18 can be continuously embedded in the threaded hole 17. When the inner side of the rotating disk 16 is tightly fitted with the laboratory table body 1, since the inner side of the rotating disk 16 is made of rubber material, the friction between the rotating disk 16 and the laboratory table body 1 increases. The support plate 11 can be fixed by the rotating disk 16, which can reduce the load during the support process of the electric telescopic rod 13, which is conducive to the long-term use of the electric telescopic rod 13.

During use, when the staff needs to transfer the experimental table main body 1, the electric telescopic rod 13 is started at this time. The extension of the electric telescopic rod 13 can drive the support plate 11 in the movable groove 9 to slide downward along the slide rail 12. When the universal wheel 15 at the bottom end of the support plate 11 contacts the ground, the experimental table main body 1 is pushed to cooperate with the universal wheel 15 to move the experimental table main body 1, which is convenient and fast to transfer the experimental table main body 1, can avoid manual transportation, can improve transportation efficiency, and can save labor costs. When the transportation is completed, the electric telescopic rod 13 is controlled to retract At this time, the support plate 11 can drive the universal wheel 15 to retract into the movable groove 9, so that the experimental table main body 1 can be in contact with the ground as a whole, which can improve the stability of the experimental table main body 1 and is beneficial to the use of the experimental table main body 1. During use, when the support plate 11 pushes the universal wheel 15 to contact the ground, the staff rotates the rotating disk 16 clockwise, and the rotating disk 16 can drive the threaded screw 18 to rotate. At this time, the threaded screw 18 can be continuously embedded in the threaded hole 17. When the inner side of the rotating disk 16 is tightly fitted with the experimental table main body 1, since the inner side of the rotating disk 16 is made of rubber material, the friction between the rotating disk 16 and the experimental table main body 1 increases. The support plate 11 can be fixed by the rotating disk 16, which can reduce the load during the support process of the electric telescopic rod 13, which is beneficial to the long-term use of the electric telescopic rod 13.
