[0022] In order to further illustrate the technical means and effects adopted by the present application to achieve the predetermined utility model purposes, the specific embodiments, structures, features and effects according to the present application are described in detail as follows in combination with the drawings and preferred embodiments.

[0023] Reference Figures 1 to 4As shown, the intelligent electrical practical training platform comprises power equipment, intelligent measurement and control devices, network equipment and computer equipment interconnected layout forming a management layer, a control collection layer and a field equipment layer, realizes remote control of main components and data reading, the intelligent electrical practical training platform of the embodiment is simulation or simulation of intelligent electrical equipment, and the motor 4 load is connected in the embodiment. Colleges and universities can organize students to understand intelligent electrical equipment cabinets, structures, principles and functions, and learn professional skills such as operation, control and maintenance of intelligent electrical equipment cabinets. The intelligent electrical practical training platform comprises a cabinet body 1, the cabinet body 1 comprises a panel operation area and an equipment installation area in the cabinet, except the load motor 4, all are installed on the metal bottom plate, and the wiring mode adopts wire slot wiring, so that the wiring is convenient, beautiful and easy to modify the control wire in the fault elimination process. The field equipment layer comprises power equipment, intelligent instruments and protection devices, the field equipment layer is responsible for collecting data and information state of the power field and sending to the communication interval layer, and the field equipment layer serves as an execution unit and executes the instructions issued by the communication interval layer; the control collection layer comprises an edge controller, is responsible for communication with the field equipment layer, collects data and parameter transmission to the management layer, and simultaneously serves as a transfer unit, receives the instructions issued by the main station layer and forwards to the field equipment layer; the management layer comprises computer equipment, is responsible for unpacking the data uploaded by the control collection layer, centralized management and analysis, and executes corresponding operation.

[0024] In the above embodiment, the power equipment comprises intelligent molded case circuit breaker 22, intelligent switch, intelligent motor controller, frequency converter 3, soft starter, intelligent power meter, motor 4 load and the like, which constitutes an intelligent motor controller loop, a frequency converter 3 control loop, a soft starter control loop and an intelligent electric energy meter loop for secondary circuit power supply monitoring. The installation layout of the intelligent equipment is roughly divided into two parts, and the primary and secondary components are distinguished from each other, as shown in the figure. Figure 3 As shown, the intelligent equipment and the edge controller adopt bus communication, and the edge controller and the management layer adopt Ethernet communication.

[0025] In the above embodiment, with reference to Figure 3As shown, the motor 4 load includes the motor 4 and the brake 5, which can provide a damping effect for adjusting the strength of the motor 4 load. The brake 5 is a magnetic powder brake 5, which is connected with the motor 4 through a spring coupling 6. In the teaching process, if it is necessary to learn and study the internal structure of the motor 4 load and the magnetic powder brake 5, it is often necessary to disassemble them, and the alignment requirement of the coupling 6 connecting the motor 4 driving shaft and the magnetic powder brake 5 is high, and students often cannot install them back. After the spring coupling 6 is adopted, a certain error generated in the alignment process is allowed, and the above problem is reduced. It also includes a guard plate 7, which is in the shape of an inverted U and shields both sides of the spring coupling 6. The guard plate 7 is provided with a wing plate at both ends, which is fixed on the lower cover plate 9 of the cabinet body 1. The guard plate 7 plays a protective role. In the learning and operation process, the high-speed rotating shaft has a certain risk. In addition, there may be multiple students, crowded environment, body contact, and clothing contact winding, which are easy to cause direct mechanical injury accidents. The accident affecting the contact with the live equipment will also cause a serious secondary electric shock accident, so special protection is carried out. The base of the motor 4 and the brake 5 is fixed on the mounting plate 8, and the mounting plate 8 is fixed on the lower cover plate 9. In some other embodiments, holes are provided on the lower cover plate 9 of the cabinet body 1, and the mounting plate 8 is provided with telescopic support legs. The telescopic support legs can adopt the electric telescopic structure in the prior art, or can adopt the structure that the upper part includes a sleeve and the lower part of the rod body extends into the sleeve and is fixed by a plurality of bolts. The support legs are supported on the ground through the lower cover plate 9, so that the mounting plate 8 is not in contact with the lower cover plate 9. However, in order to avoid dust, mice, cockroaches and other animals from entering the cabinet body 1, a baffle 10 is provided above the lower cover plate 9, the baffle 10 is sleeved on the support leg, the baffle 10 contacts with the lower cover plate 9 through a rubber pad layer 11, and the baffle 10 and the mounting plate 8 are connected through a compression spring 12. When the cabinet body 1 needs to be moved, the support legs are retracted so that the lower cover plate 9 bears the mounting plate 8. As described above, due to the use of the spring coupling 6, the connection of the coupling 6 is not very accurate, and the motor 4 may generate relatively large vibration. Therefore, the embodiment actually separates the motor 4 load from the cabinet body 1, so that the vibration of the motor 4 does not affect the cabinet body 1.
