DYDLX-03 Change Duty Duty Duty Duty Electric Experimental Platform

As China's large and medium-sized enterprises increase year by year, the electric power industry develops rapidly, the demand for electricians continues to increase, and there is a shortage of electricians on duty in power transformation and distribution rooms; the "Skills Tr*ning and Assessment System for Electricians on Duty in Power Transformation and Distribution Rooms" is to cooperate with the assessment of electricians on duty in power transformation and distribution rooms , based on the "Occupational Standards for Electricians on Duty in Transformer and Distribution Rooms" of the Ministry of Labor and Social Security, with reference to relevant vocational skills compiled by the Ministry of Labor and Social Security, the Electric Power Industry Vocational Skills Appr*sal Guidance Center, the Machinery Industry Vocational Skills Appr*sal Guidance Center, and the Electric Power Department of the Ministry of Energy. Appr*sal guide, tr*ning syllabus, tr*ning materials, and question bank are developed. This system uses a 35KV substation as a primary system model , using some typical and commonly used primary real components combined with a system simulation control panel. The tr*ning project involves high and low voltage electrical appliances and complete sets of equipment in the power transformation and distribution room, monitoring and meter reading, Power relays and relay protection, switching operations, typical low-voltage electrical lines, etc. can be used as practical tr*ning equipment for students in power supply and distribution majors and related majors in vocational schools and technical schools, and as a tr*ning and assessment platform for electricians on duty in power transformation and distribution rooms.
