3. Basic configuration and functions: The equipment m*nly consists of tr*ning screens, tr*ning hanging boxes, tr*ning equipment, tr*ning tables, etc.
(1) Tr*ning screen: The tr*ning screen is made of iron with a double-layer matt dense pattern spray-p*nted structure and an aluminum alloy panel. It provides AC power and DC stabilized voltage and current power supply for the tr*ning hanging box. The specific functions are as follows:
1. External The power input indicator light is on (reminding the operator that the external power supply has been connected to the tr*ning platform ).
2. Push up the three-phase leakage switch, the three-phase power supply supplies power to the tr*ning hanging box, etc., and three 450V voltmeters indicate the output line voltage.
3. Low-voltage AC power supply: Output 3V, 6V, 9V, 12V, 15V, 18V, 24V low-voltage AC power supply.
4. Provide 2~220V sockets to provide working power for external equipment.
5. DC stabilized voltage and current power supply: The voltage is continuously adjustable from 0-30V, the built-in relay automatically shifts, the multi-turn potentiometer continuously adjusts, the output current is 2A, and it has a preset current limiting protection function.
Teacher teaching design system: This system is in apk format and can be used on PC or mobile. This system can manually set faults or automatically set faults. This system can manually set faults by selecting the green box in the circuit diagram. points (up to 39 fault points can be set), or the system can automatically set one random fault point, two random fault points, three random fault points, four fault points randomly, and five fault points randomly. Settings, this system has toolbox, component library, magnifying glass, circuit diagram and other functions. You can select a multimeter for testing through the toolbox, select appropriate components through the component library, and clearly understand each component and circuit through the magnifying glass. This system allows students to understand the working principle and circuit structure of the motor star-delta start control circuit through the setting of faults in the motor star-delta start control circuit and various investigations.
Three-purpose meter simulation software: This software is in apk format and can be used on PC or mobile terminals. The functions of this software are: measurement of resistance, measurement of AC voltage (measuring transformer, if the transformer is burned out, it is useful for measuring When the meter is running, black smoke will appear and you can reset the multimeter), determine the polarity of the transistor, measure the DC voltage (the light will turn on when the ammeter is turned on), measure the DC current, and judge the quality of the capacitor. This software can drag the red and black pen tips at will. When the two pen tips are dragged and positioned on the object to be measured, a red circle will be displayed. If the positioning is not accurate, no red circle will be displayed, and when incorrect operations are performed (such as the wrong range selected, If the measured data is wrong, etc.), the meter pointer will not respond, prompting errors and re-measurement, etc. This multimeter can select AC voltage gear, DC voltage gear, resistance gear, current gear, resistance adjustment to 0, and can enlarge the display data. Clearly view the measured data size. Students can learn the correct use of multimeters through this software.
