Electrical Electronics and Automatic Control Experiment

Electrical Electronics and Automatic Control Experiment,Electric vehicle high -voltage safety system experimental device

I. Overview

"Electric Electronics and Automatic Control Technology Experimental Device" According to the latest unified textbooks "Electronics Electronics Technology" (fifth edition) (compiled by Wang Zhaosan of Xi'an Jiaotong University), "Electric Power Drag Automatic Control System" (3rd edition) (Chen Bo Shi, Chen Bo Shi, Shangh-- University), and other experimental outlines, absorb the advantages of domestic and foreign products, fully consider the current situation and development trend of the laboratory, and carefully develop it. The structure, complete function, good reliability, and high cost performance in similar products.

2. Features

1. Comprehensive strong This device integrates experimental projects such as electrical electronics, semiconductor variables, cross -flowing speed regulation, AC frequency conversion, motor control, and control theory of various schools in China.

2. Strong adaptability can meet the experimental teaching of the corresponding courses of various schools. The depth and breadth can be flexibly adjusted as needed. The popularization and improvement can be organically combined according to the process of teaching. Extend the function or develop new experiments. Just add parts and never eliminate.

3. The whole set of strong settings from dedicated power, motor, and other experimental components to experiments to connect to the dedicated wires, and the performance and specifications of the supporting components are closely combined with the needs of the experiment.

4. Strong intuitive experimental pendies adopt a separatist structure. The component panels are significant, the graphic line is clear, each pendant task is clear, and the operation and m--ntenance are convenient.

5. Scientific strong device occupies a small area, saves experimental rooms, and reduces infrastructure investment. The supporting small motors are specially designed to simulate the characteristics and parameters of small and medium -sized motors. Small, neat and beautiful, improve the experimental environment; rich experimental content and reasonable design. In addition to deepening theoretical knowledge, design experiments can be opened in combination with actual situation.

6. Open -open control screen power supply uses a three -segregated transformer isolate, and has a voltage leakage protection device and a current leakage leakage protection device to ensure the safety of the operator. All power supply output has monitoring and short circuit protection. The measuring instrument has a reliable protection function, which is safe and reliable; the control screen also has a timer and alarm recorder to provide a unified standard for the assessment of students' experimental skills. Because the whole set of devices are carefully designed, and the quality of the reliable component and the reliable process as the guarantee, the product performance is excellent. All these are open laboratories and create conditions.
