The desktop is made of high-density medium-density fiberboard, the operating edge is trimmed, the edge is thickened and polished with a small R shape, and the slide r*l adopts a silent slide r*l; the desktop height adopts an ergonomically appropriate height of 800mm.
(II) Tr*ning table
1. The m*n part of the tr*ning table adopts a full steel structure, with matte sprayed steel plates, beautiful and durable. The table top is printed with aluminum-plastic plate. The entire tr*ning table consists of a leakage protection switch, a fuse, a switching power supply, a digital display timer, an intelligent card swipe start circuit board, a single-phase transformer, an AC contactor, a digital clamp ammeter, a lighting fluorescent lamp, various buttons and safety terminals.
2. This tr*ning platform installs the clamp ammeter test object components on this tr*ning platform after safe processing, and adopts plug-in safety wiring method. Students can connect transformers as many times as they want according to the working principle of transformers, and use clamp ammeters to measure circuits in a standardized manner, which achieves the purpose of safe tr*ning without damaging components.
3. This tr*ning platform uses two opening methods: key emergency opening and card swiping, which is convenient for teachers to manage tr*ning equipment, prevent unauthorized persons from operating equipment at will, and effectively protect students' personal and equipment safety.

system The model in the software can be rotated 360°, enlarged, reduced, and translated, and there are general interactive buttons: return, home page, and help. There are prompts for all virtual simulation task processes, and the software automatically checks after completing a task. There is an experimental task
1, basic solid, above the tool library ( the XYZ space coordinate icon automatically rotates with the rotation when the model
is rotated.) A. Plane solid: The experimental steps are divided into experimental tasks (text prompt tasks) - build models (drag the model in the tool library to the three-projection surface system, and the projection will automatically appear. There will be prompts when the selection is wrong) - change posture (change by clicking the up, down, left, and right arrows) - select projection (enter the answer interface, and select the three-dimensional projection diagram completed at this time from the 6 items)
