1) Composition and structure characteristics 1. Simple structure: the overall structure has a skeleton and an executive part of the control cabinet, 2. Convenient operation, all operation, display and execution components are installed with external leakage, which is convenient for observation and operation 3. The overall frame is made of stainless steel to prevent the equipment from rusting 4. Only single-phase three-wire AC power supply can be put into use, and the floor space is small, saving housing and reducing infrastructure investment 5. The structure design of the open experimental object makes the experimental object intuitive and easy to understand. 6. The design of the hardware object fully considers the certainty of its mathematical model, which is consistent with theoretical textbooks. 7. The parameters and characteristics of the selected instruments meet the design requirements of the system, and the experimental results are ideal. 8. The disassembly and assembly of instruments and meters deepens students' understanding of engineering instruments and meters, especially the internal principles of devices. 9. A variety of control signals, a variety of control signals and control methods can be selected according to the experimental project 10. You can do DIY experiments; the training device can change the experimental objects and connection methods according to user requirements 11. Human-computer interactive experiment. The configuration software is used for interactive operation, that is, what you see is what you get, and data can also be collected. 2) Security protection 1. The power supply has protections such as leakage, overvoltage, overcurrent, and short circuit, which protect the safety of trainers. 2. Separation of water and electricity; that is, the control system and the execution system are separated, and all the wiring of the execution system is treated with waterproof measures 3) Configure teaching software

Boiler heating program control protection system 1. The boiler heating liner is equipped with a water level and liquid level protection device, and the control system can only control the heating after the water level reaches the specified height. 2. The power control switch of the electric heating tube adopts a key switch, which is easy to manage. Power protection measures 1. There is a current leakage protector. 2. The two-phase power supply has a fuse to prevent disconnection. Power start-stop control mode; Use the start-stop button to control the contactor to control the start and stop of the power supply. Leakage protection device and safety and safety commitment; Reliable protection functions of various power supplies and various instruments

DLWD-DJQD01 electrical drive training system is a reference to the German advanced vocational education concept to the work process-oriented to maintenance of electrician as the carrier, respectively, maintenance of electrical entry, commonly used electrical tools and instrumentation, indoor line installation, The basic control of the motor line installation and maintenance, in order to achieve the students on the maintenance of electrical workers a comprehensive understanding of the students to improve the practical ability.
