Description
Structure
Yl-158ga yl-158ga electrical control technology training and assessment device.It is composed of training cabinet body, door panel electrical control components (components), instruments, etc., training assessment unit hanging board, typical machine tool circuit hanging board, motor unit, motion unit, temperature control component, mesh hanging board, etc.Its appearance is shown in the figure.
Yl-158ga electrical control technology training and assessment device is composed of various simple or complex electrical control systems through the corresponding hanging board components to complete the teaching and training.
composition
Main command electrical and meter units
The panel of the main command electrical and instrument unit is the control signal and display (indicating) unit in yy-158ga, which plays a role in providing control signals to other units in the system in the whole electrical control system.It includes the control and protection of incoming line power supply, main command electrical control components, indicator lights, touch screens, display instruments, emergency stop buttons and other devices.
PLC control unit hanging board
PLC control unit panel is the main control unit of yl-158ga electrical system program control. In the whole system, it plays an important role in input signal processing and electrical control signal output.Including PLC, analog module, expansion module, 0~20mA standard constant current source, 0~10V standard constant voltage source, digital display instrument, inverter, servo driver, stepper driver and other devices.
Relay control unit panel
The panel of relay control unit is a unit that realizes the basic motor drag control in yl-158ga. It plays a role in the amplification and execution of PLC control signal in the whole electrical automatic control system.At the same time, it can realize independent relay dragging function.It includes circuit breaker, fuse, contactor, thermal protection relay, trip switch, time relay, etc.At the same time, it is also equipped with the motion device of the trolley driven by servo and stepper motor (which can be converted to each other), and equipped with sensors, micro switch, ball screw, incremental encoder and so on.
Power electronic unit panel
Power electronic unit hangs Taiwan as a relatively independent three-phase fully-controlled bridge thyristor rectifier dc speed regulation system and dynamometer, measuring torque and speed digital display instrument, through an external circuit which can realize the speed control and start stop control, can realize open loop control, single closed-loop control (current loop), double closed loop control, current loop and speed loop) function, fault set at the same time can also, through the use of instruments such as multimeter and oscillograph to fault phenomena analysis, and computer troubleshooting.Including three-phase thyristor full wave rectifier dc speed control system (current ring and speed ring), power meter (including power measurement, moment measurement and speed measurement), three-phase rectifier transformer and synchronous transformer, disk potentiometer load, dc motor unit, fault setting unit, excitation power supply and other components.
Typical machine tool circuit intelligent assessment unit hanging board
This unit through the typical machine tool circuit fault phenomenon analysis and judgment, measurement and inspection of fault points, using the computer can only check the software to eliminate the fault, complete the machine tool circuit fault check and elimination.Including X62W milling machine circuit, T68 boring machine circuit.Computer intelligence assessment and so on.
