2. Functional characteristics

1. The m--n components are installed on the tr--ning platform to ret--n the electrical connection method of the original car. It can be convenient to disassemble after power off. Tr--ning and disassembling wire beams and electrical appliances, master the m--n points of disassembly and safety protection of high -voltage system components.

2. The cover of the power high -voltage distribution box is modified by transparent 5mm organic glass to clearly observe and understand the principle of control and internal control elements.

3. Driving the transmission system tr--ning table high -voltage power supply is provided by power battery and management system tr--ning description, and works with the tr--ning platform of the power battery and management system.

4. Teaching board fully displays the working scheme of the electrical drive system, installs the detection terminal, and can directly detect the electrical signals of the circuit component of the system on the panel, such as resistance, voltage, current, frequency, waveform signal, etc.

The panel adopts a ** aluminum -plastic plate with resistance, pollution resistance, fire prevention, and moisture -proof, and the surface is sprayed by special crafts to spray primer p--nt; panel prints with color circuit diagrams that will never fade, etc.;

5. Install the original car brake at the drive shaft output end, simulate the vehicle load system, and by adjusting the load size of the two ends to truly display the electric drive transmission system (start, accelerate, uniform speed, deceleration, parking, climbing, climbing, etc.), and Data change laws such as voltage.

6. The device consists of a platform and a teaching board. The platform is placed horizontally and the original car parts are installed; 4 self -lock -locking wheel devices are installed at the bottom.

7. The panel part uses a 1.5mm cold plate stamping and forming structure, which is beautiful in shape; the bottom part is welded with steel structure, the surface is treated with spraying process, a self -locking foot wheel device, and a countertop of about 30cm on the teaching plate base, which is convenient for placing information , Light detection instrument, etc.

8. Equipped with intelligent fault settings and assessment systems, the fault point is m--nly set in low -voltage control lines to ensure the safety and tr--ning of the high -voltage system and the ability to tr--n real car f--lure.

9. The tablet is equipped with an insulated floor (insulation and pressure -resistant national standard product ground glue).

10. Supporting tr--ning guidance, including system work principles, tr--ning subjects, fault settings and removal.

1. Pulse/turntable extraction unit operation tr--ning device system composition and characteristics

1. Framework \ st--rs \ guardr--l: Frame length × width × height: about 3000 × 1500 × 3500mm, and the width of the st--rs is 700mm. The total installation size of the equipment: 3700 × 1500 × 3500mm. The whole machine adopts steel installation framework (two layers of design, one layer of flat planes are convenient to operate, rep--r, and enter and exit. The second floor has a safe diagonal ladder and a guardr--l, non -slip pattern plate), anti -rust red dandan p--nt, and spray p--nt treatment. Fastener: with flange, valve, framework, st--rs, guardr--ls, brackets.

2. The system consists of a pulse/turntable extraction dual extraction unit operation tr--ning device object. All st--nless steel equipment is finely polished by st--nless steel, which reflects the perfectness of the entire device. The tower section is made of high -quality inorganic glass, which has good visual effects. The pulse extraction of the tower body: the body of the glass, the hard glass φ125 × 1200mm; The diameter of the turntable is 85 × 1500mm, st--nless steel/static ring.

3. The extraction tower extraction can use a special high borosilized glass visual essential balance. The running medium of the device is kerosene -benzoic acid -aquatic system, which can be used to use light phase materials.

4. Local Intelligent Instrument Electric Console: About 1650X700X1400 Steel Spitting Piano Structure Local Instrument Electric Operation Piner (including RS485 communication interface control smart instrument, embedded microcomputer position and switch position, and cont--ns DCS connection Entrance). Internal installation of leakage protection of --r switch and current leakage protector fully consider personal safety protection; at the same time each set of strong electricity output has knob switch control to ensure the safety of the equipment and convenient operation control; Device, solid -state relay, self -lock switch, plastic copper wire, rubber sleeve, shielding thread, aluminum alloy wire groove, etc. The device can be independently measured and controlled by the on -site industrial control operating table by the intelligent instrument + industrial control configuration software with the RS485 communication bus + industrial control configuration software to complete each tr--ning program. The system can also use DCS control systems.

4. The device can reflect the factory situation, try to get closer to the actual situation of the factory, and highlight the focus; the skills operation tr--ning, process indicators control operation skills tr--ning can be used for device driving preparation, driving, normal operation, parking, equipment m--ntenance and other aspects. Teaching and tr--ning requirements for the tr--ning and tr--ning outlines of crafts, technicians, and ** technicians.
