I. Overview

"Electronic Electronic Technology Experiment, Tr--ning Device" is a course of experimental tr--ning outlines such as "Electric Electronics Technology" and "Semiconductor Transformation Technology" and "DC Specific Specification" opened by colleges and universities. Tr--ning device. At the same time, it can be used as a skill tr--ning device for primary and intermediate m--ntenance electricians, ** electricians, technicians and ** technicians.

2. Technical characteristics

1. Safety and reliable: This device is powered by isolation transformer, and has ground protection and leakage protection functions. The safety meets relevant national standards to ensure personal safety; according to the characteristics of different experimental items, two different experimental connection cables are equipped , The strong electric part uses a high -reliable sheath structure pistol plug connection (there is no possibility of electric shock). The weak electric part uses elastic 铍 铍 铍 naked exposed structure connecting cables. Both wires can only be matched with the corresponding inner holes. This is great. Improve the safety and rationality of the experiment.

2. Strong scalability: It can meet the experimental teaching of the corresponding courses of various schools. The depth and breadth of the experiment can be flexibly adjusted according to needs, and the popularization and improvement can be organically combined according to the process of teaching. The device adopts a pendant structure and is convenient for replacement. If the expansion function is required or developed new experiments, you can just add a part and never eliminate it.

3. Strong intuitiveness: The experimental pendant adopts the form of separation structure. The front is the experimental schematic diagram and test point, which enhances the students' perception and rational understanding of the experimental content; It is conducive to improving students' practical ability.

4. Strong advancedness: The experiment involves four commonly used category variable -flow technical experiments, and most of them are widely used practical circuits, but for the convenience of teaching, but also the simplicity of this device; this device is considered from the height of the new device. The characteristic experiments of new devices, the driver of the new device, and the modern power electronic technology experiments of typical new device applications allow students to have sufficient understanding and understanding of new devices and keep up with the pace of the times.
