③used for teaching and learning of the electricians training and technical skills appraisal in the related enterprises;
④ used for teaching and learning of the electricians technical skills training in the related enterprises;
⑤ Electrical automation. Used for teaching and learning of the electric power supply technology, related majors learning, course teaching and learning.
4) Practice. For students to improve their work and operating skills;
5) Demonstrative. The cabinet has windows for students to see the work inside.
6) Safety. High-voltage part has AC 3-phase & 5-line 380V inlet. The vacuum breakers, and other high-voltage elements are the real 12KV voltage degree elements, according to the safety requirements on the power supply in schools.
7) Real. The real high & low voltage electric distribution cabinet is used for students to learn how to operate in the system. With front and rear windows, to achieve teaching and learning demonstration functions, and for students how all parts and elements work inside the system. The whole equipment includes 10KV/0.4KV power supply system.
YL-160-5(GCK) (KYN28A) high & low voltage electric distribution system has XNR-800 PC protector, with group software for “4-remote control” functions.
Total cabinet installation, upper (lower) inlet and outlet.
The cabinet has the single-circuit circuit power supply. In training, students can learn how to operate and connect the insulation switches, breakers, contactors, voltage mutual-inductors, current mutual-inductors, instruments and meters, compensation capacitors, other controllers, cables and wires.
Training functions and projects:
1. Training functions
1) The real 10KV work conditions: as same as a real system, all safeguard elements and instruments run as same as the real ones in the real industry and life, the switches and loads work as same as the real ones, also the capacitors work as same as the real ones,
2) System safety: without the real 10KV power supply, but it works as same as that; the system has various safeguard functions, with leaks safeguard functions; the errors made by students in the system will not lead any humans injury and system accidents.
3) energy-saving: no real loads, save power;
4) System functions: The system communication control software monitors the power supply management flow: power supply plan design and audit, on-site acceptance, power supply, safety check, dispensable elements replacement and relays safeguard debugging functions.
5) Measurement ends: the high-voltage and low-voltage measurement will be done on these ends, and the simulated circuit and transformer will be ready for the loss measurement; the students also can calibrate the power measurement on-site. The high-voltage PT, CT capacity test will be done. The high-voltage PT secondary voltage-drop test will be done.
6) functions: “teaching, learning, practice and test” skills training system.
