Maintenance Electrician Skill Training Assessment Equipment    Model:QSWD-Άρ


    QSWD-I is elaorately developed according to the professional skill assessment guidance center of Department of Labor.This equipment is suitable for the student experiment, and for the primary and junior maintenance electrician skill assessment.


1.All control circuits and components are fixed on the control panel,for easy operation and replacing,and for better understanding of students.

2.The electrical supply for this equipment is Three-phase 4-wire power,thus is easy to install.

3.The motor and circuits are specially designed to simulate all kinds of industrial motors and power drive systems. It satisfies the maintenance electrician`s skill training of installation and testing,fault analysis and troubleshooting.

4.The equipment has perfect safety protection function to insure the safety of operators.Input parts are equipped with current-leakage protection devices,the power output has short-circuit protection and surveillance functions,the measuring instruments are equipped with reliable protection and surveillance function.The control screen also provides experimental device management for the students experiment with a skills assessment management platform.

5.All the components have adopted guidelines to the wire connector;students only need to connect the components to the terminal.

III.Technical Conditions

1.Input voltage: Three-phase 4-wire system 380V~10%,50HZ

2.Work environment:environmentail temperature range of -5~+400C,relative humidity<85%(250C),elevation<4000m
