1. Overview

The device is mainly composed of a training desk, a mesh plate, and training components. Students can reasonably layout the components according to the training circuit, and complete the installation and wiring by themselves, which is close to the industrial site. It can complete comprehensive training such as simulation operation, installation and commissioning of machine tool circuits, motor control circuits, and lighting power distribution, so as to train students’ practical ability and operational skills. Training projects can be determined independently, and corresponding components can be selected according to the selected projects. The device can also be used as an assessment equipment for electrician skill examinations.

1. Features

1.The components of the electrical control circuit are all mounted on the mesh plate, which is convenient for operation, easy to replace, and easy to expand functions or develop new training projects (additional training projects can be added by purchasing additional components).

2.The operation platform can be put into use only with a three-phase four-wire AC power supply, which covers a small area, saves training rooms, reduces infrastructure investment, and has significant economic benefits.

3.The training bench is equipped with two sets of independent power supplies, which do not interfere with each other, so that two students can carry out training at the same time.

4.It is equipped with voltage-type leakage protector and current-type leakage protector to ensure the safety of operators. The power output is equipped with monitoring and short-circuit protection functions, which makes the use safe and reliable.

III. Technical Performance

1.Input power supply: three-phase four-wire system ~ 380V±10% 50Hz

2.Temperature: -5℃～+40℃, relative humidity < 85% (at 25℃)

3.Device capacity: < 1.5KVA

4.Overall dimensions: 1600mm×700mm×1690mm

1. Configuration of the Training Bench

1.Public part: Equipped with voltage-type leakage protection and current-type leakage protection. The external power input is indicated by an indicator light. An emergency stop button is provided. In case of emergency, press the button to cut off the main power supply of the training bench.

2.Each group is provided with two types of power supplies: line voltage 380V or phase voltage 220V, a single-phase power socket, and a line voltage input indicator.

3.Each group is provided with 3V, 6V, 9V, 12V, 18V, 24V, 36V low-voltage AC power supplies.

4.Each group is provided with a constant current and regulated power supply with a voltage of 0-30V and a maximum current of 3A. It has a built-in relay for automatic shifting, a multi-turn potentiometer for continuous adjustment, and a digital meter to indicate current and voltage values.

5.The training desk is of iron double-layer matte dense-grained spray structure. The desktop is a fireproof, waterproof and wear-resistant high-density board. The structure is firm, and the shape is beautiful and generous. There are drawers on the left and right sides of the desk, and a component storage cabinet at the lower part.
