1. Product Overview
This tr*ning device is developed for courses such as "Basics of Motor Driving", "Factory Electrical Control", "Ship Electric Driving" and "Ship Electrical" offered by vocational colleges such as " Ship Electrical Automation" and "Ship Electromechanics". This tr*ning device includes motor electric driving, electric driving low-voltage electrical control, ship deck machinery electric driving control and other contents. It can be used as a practical teaching equipment for ship engine engineering majors , and can also be used as an ideal tr*ning equipment for ship electrical engineering technicians. 2. Technical performance 1. Input power: three-phase four-wire (or three-phase five-wire) ~380V±10% 50Hz 2. Working environment: temperature -10℃～+40℃ relative humidity <85%(25℃) altitude <4000m 3. Device capacity: ≤1.5kVA 4. Weight: 300kg 5. Virtual simulation system for electricity safety and electric shock first *d: The software adopts a virtual screen combining two-dimensional and three-dimensional to teach students electricity safety and first *d methods. The software is equipped with single-phase electric shock, two-phase electric shock, step electric shock, low-voltage electric shock first *d, high-voltage electric shock first *d, artificial respiration rescue method, hand-holding breathing rescue method, chest compression rescue method and other principle explanations and teaching. Single-phase electric shock is divided into m*ntenance of live disconnection, m*ntenance of socket electric shock, outdoor electric shock and other principle demonstrations. The teaching of low-voltage electric shock and high-voltage electric shock m*nly expl*ns and demonstrates to students how to rescue people who are in low-voltage electric shock or high-voltage electric shock. Artificial respiration rescue method, hand-holding breathing rescue method, and chest compression rescue method are displayed using 3D virtual simulation technology. After rendering and polishing, the model looks the same as the real part, and the picture is realistic. Through practical tr*ning, students can be educated on safe use of electricity in the tr*ning room, improve their safety awareness, and learn some self-rescue methods. Students can take cert*n safety measures to protect themselves when they encounter danger, and are familiar with the causes of various electrical accidents and practical operational measures to deal with electrical accidents, so as to reduce the occurrence of electrical accidents. In order to prevent false bidding, this system demonstration is carried out at the bidding site. 6. Single-chip microcomputer , PLC programmable design and control virtual simulation software (copyright certificate and demonstration video are required): 1) This software is developed based on Unity3D, with built-in experimental steps, experimental instructions, circuit diagrams, component lists, connection lines, power on, circuit diagrams, scene reset, return and other buttons. After the connection and code are correct, the 3D machine tool model can be operated by the start/stop, forward movement, and reverse movement buttons. When the line is connected, the 3D machine tool model can be enlarged/reduced and translated. 2) Relay control: Read the experimental instructions and enter the experiment. By reading the circuit diagram, select relays, thermal relays, switches and other components in the component list and drag and drop them into the electrical cabinet. The limiter is placed on the 3D machine tool model. You can choose to cover the cover. Some component names can be renamed. Then click the connection line button to connect the terminals to the terminals. After the machine tool circuit is successfully connected, choose to turn on the power and operate. If the component or line connection is wrong, an error box will pop up, and the scene can be reset at any time. 3) plc control: the experiment is the same as relay control, with the addition of PLC control function. After the connection is completed, press the PLC coding button to enter the program writing interface, write two programs, forward and reverse, with a total of 12 ladder diagram symbols. After writing, select Submit to verify the program. After successful verification, turn on the power to operate. Errors in components, line connections, and code will pop up prompt error boxes, and the scene can be reset at any time. 4) MCU control: the experiment is the same as relay control, with the addition of MCU control function. After the connection is completed, press the C coding button to enter the programming interface, enter the correct C language code, and submit the verification successfully. Turn on the power to operate. Errors in components, line connections, and code will pop up prompt error boxes, and the scene can be reset at any time. III. Practical tr*ning projects 1.
