　　Equipment

　　(1) 02 The main control screen of the power control box is an iron double-layer matt dense grain spray structure and an aluminum panel.

　　(2) The main control function board is equipped with resources

　　1. The three-phase four-wire power input, after passing through the leakage protector, passes through the main switch, and controls the on-off of the contactor through the start and stop buttons, and is equipped with an emergency stop control button;

　　2. There is a 450V pointer AC voltmeter on the control screen, and the three-phase grid voltage can be observed by switching the band switch;

　　3. Timer and alarm recorder (service manager), usually used as a clock, with functions such as setting time, timing alarm, cutting off power, etc.; it can also automatically record leakage alarms and power short-circuits caused by wiring or operation errors. The total number of times provides a unified standard for the assessment of students' practical training skills;

　　4. AC circuit measurement meter: Eight-digit LED display, which can simultaneously measure current I, voltage V, power KW, electric energy KWh, and working time T in the working circuit. Accuracy class 1.0.

　　5. AC low-voltage power supply: There is a transformer, the primary side is 220V, the secondary side is 26V and 6.3V AC voltage, 6.3V is used for the signal indicator power supply, and 26V is used for the AC power supply of the rectifier circuit in the energy consumption braking;

　　6.4 5408 diodes, used for the rectifier circuit of dynamic braking;

　　7. Three 75Ω/75W resistors are used for the step-down start of the motor, and one 10Ω/25W is used for the energy consumption braking of the asynchronous motor.

　　(3) Training table

　　The training table is an iron double-layer matt dense grain spray structure, and the tabletop is a fireproof, waterproof, wear-resistant high-density board, with a solid structure and beautiful appearance. There are two drawers (with locks) on the left and right sides of the table, and there are cabinets for placing pendants and training items respectively.
