3.1 Synchronization of Experiment and Teaching

QY-BPTS-2 model frequency converting speed regulating technology training device relates 18 experiments projects; it assumes the practice teaching content of the frequency converting speed regulating and other relative majors. Its experiments are closely related with Frequency Converting Speed Regulating Technology and Application, Automation Technology and Application, and they complement each other. Thus making the practice and teaching proceed at the same time, combining theory and practice together; make it convenient for teachers to teach and students to learn.

3.2 Strong Safety Guarantees

The training device is set with multi-protection, like over current, ground protection, short circuit, phase loss. In addition,the module control panels that the users touch frequently is made of high insulation fold resistance board. Besides, the table is made of high insulation high density fire board to protect the operator’s personal safety effectively.All the practice connection ports on the experiment modular is secure sockets, and all low voltage connection ports are with size D3, while high voltage connection ports are with D4. Besides, different safety jacks in the modules is with different colors, thus effectively avoid misuse for the students in the practice.

3.3 Open Design Concept

1、The training device is comprised of Power module, control module, frequency converter module, relay module, contactor module and so on. These modules are separate while combined organically. It makes the users to know the frequency converter speed control system clearly and intuitively.

2、The core components in the training device is installed in a transparent way, making it easy for the users to get know of the components further and till the whole system.

3、The experiment table, T shelf and the table legs are all fixed and installed in a hardware-connecting way. They can be handled at any time for some special occasions. Each experiment module can be removed via the T shelf notch to meet different requirements for different users, thus making the experiment practice very convenient.

4、Part of the experiment modules adopts parallel design, making it convenient to do experiment, also avoiding the fly lines.

3.4 Ideal Training Platform

All the experiment items training system involves need the user to operate it actually, includes circuit design, line connect,operate etc. In addition, The experiment items the training device involves is based on the principle of from basic training to consolidation exercise, from easy to difficult, thus it is convenient for users’ training and learning.
