Advanced electrician course | Advanced electrician certificate | Advanced electrician experimental bench | Advanced electrician training assessment laboratory equipment | Advanced electrician training assessment device
JG-125 advanced electrician and electric tractor training assessment device (PLC control)

It is a new generation of training, study, theoretical verification, practical operation ability, and assessment designed in accordance with the content requirements of "Worker Technical Grade Standards" and "Occupational Skills Appraisal Specifications" issued by the Ministry of Labor and Social Security and based on the actual situation of junior electrician training assessment. Appraised as a multifunctional cabinet-type device. The entire equipment is a standard electrical control cabinet as the main cabinet. Using the double-sided space of the cabinet, the electrical equipment and supporting experimental equipment can be arranged to complete the practical operation project of the electric drag control and lighting circuit in the primary electrician assessment and evaluation. The electrician 2. The electric tractor practical training and assessment device adheres to the principle of combining theory with practice, highlights skill training, and focuses on pertinence, practicality, and scientificity. The cabinet has been designed reasonably by the use of many vocational skill training centers, vocational schools, and technical schools throughout the country. Convenient operation and small footprint. In order to extend the service life of electrical appliances, the contacts of all electrical appliances are connected to the terminal blocks, and then students are connected to the terminal blocks, and the motors and electrical appliances are connected to complete various control experiments to effectively reduce material consumption and extend the service life. This set of equipment is suitable for all labor occupation skills appraisal departments, and at the same time it is suitable for the teaching and training assessment of major electricians and electric tractors in majors, technical secondary schools, technical schools, and vocational schools.
