KHWX-081 junior maintenance electrician training assessment device

An overview of the primary maintenance electrician training assessment device uses international popular modular design, configure the appropriate training module depending on the content of training assessment, convenient training, rational layout, easy to extend to upgrade, training covering electrical instruments, Electrical wiring technology, electronics, electrical lighting, power distribution, electric drive, electric shock first aid, fire safety, in line with national occupational standards electrician primary education, training, examination requirements, adapt to various vocational schools, technical schools, secondary schools, labor Teaching Training and skills accreditation bodies and other units, training assessment, skills identification. Second, the technical performance 1. Input voltage: three-phase four-wire 380V ± 10% 50Hz 2. Working environment: temperature range -5 ~ + 40 ℃ 3. Installed capacity: <1KVA 4. Security: leakage current ≤30mA overcurrent protection, fuse protection 5. Dimensions: 1600mm × 700mm × 1450mm Third, the basic configuration and function of the training bench training device screen mainly by training, practice hanging boxes, training equipment, training tables, etc. components. (A) training screen training screen for the iron double matte dense spray pattern, aluminum panels, the training hanging box AC power, DC stabilized power supply, specific functions are as follows: 1, the external power supply Enter the indicator light (alert the operator with an external power supply is switched on training bench). 2, onto the three-phase leakage switch, three-phase power supply to training and other hanging box, three 450V voltage meter indicates the output line voltage. 3, low-voltage AC power supply: Output 3V, 6V, 9V, 12V, 15V, 18V, 24V low-voltage AC power. 4, to provide ~ 220V socket 2, provides operating power to an external device. 5, the DC stabilized power supply: voltage 0-30V adjustable, built-in relay automatic transmission, multi-turn potentiometer continuously adjustable output current 2A, with a preset current limit protection. (B) training and equipment hanging box with 1, KH-61 maintenance electrician hanging box (a) 2, KH-62 maintenance electrician hanging box (b) 3, KH-63 maintenance electrician hanging box (c) 4, KH- 64 maintenance electrician hanging box (D) 5, KH-65 maintenance electrician hanging box (V) 6, abalone universal training board 2 7, resistors, potentiometers, capacitors, diodes, transistors, thyristors and other equipment batch . 8, three-phase squirrel cage induction motor 180W Y / △ 1 station 9, the whole room safe fire extinguisher Taiwan (iii) training tables aluminum wooden structure, desktop is fireproof, waterproof, wear-resistant high-density, nice shape, sturdy durable.
