Comprehensive Advanced Maintenance Electrician Skills Training & Assessment Bench Didactic Workstation For Vocational Electrical Lab Skill Evaluation

This device mainly consists of a training table, a main unit, an external instrument power supply box, a training hanging box, a perforated board, and training components. Students arrange the components rationally according to the training circuit. Installation and wiring are all completed by the students themselves, closely resembling an industrial field. It enables students to simulate basic electrical and electronic circuits, motor control circuits, and lighting power distribution. It can also provide comprehensive training in PLC programmable circuits, frequency converters, touch screen integrated application circuits, and electronic technology application circuits. Through a series of project-based training, students' hands-on abilities and practical skills are cultivated. The training projects can be determined by the students themselves, and appropriate components are selected based on the chosen projects. This device can also be used as an assessment tool for electricians.

• The training uses a combination of perforated plates and hanging boxes, which makes the training convenient to operate, easy to replace, and easy to expand functions or develop new training projects. It is conducive to hands-on ability and is close to the industrial site.
• Highly comprehensive: It can provide skills training in multiple disciplines, including electrical engineering, electric drive, electrical control, and PLC integrated control.
• The operating console only requires a three-phase four-wire AC power supply to be put into use. It occupies a small area, saves on training room space, reduces infrastructure investment, and has significant economic benefits.
• Equipped with voltage-type and current-type leakage current protectors to ensure operator safety; power output is monitored and short-circuit protected.
• The 380V AC output is equipped with a single-chip microcomputer-controlled overcurrent protection device. If a phase-to-phase or line-to-line direct short circuit or overload current exceeds the set value, the system will cut off the main power supply to ensure the safety of the equipment.
