Electricity Safety Experiment

 

Safety electricity tr--ning desk is suitable for curriculum teaching tr--ning such as "Electrical Safety Engineering", "Safety Electricity", "Electricity Operations", "Electrician Technology", "Introduction to Electricity Engineering". Students can teach through tr--ning, familiar with the reasons for various electrical accidents, and practical measures to prevent electrical accidents, so that students can understand electrical accidents, attach importance to electrical accidents, improve on -site prevention accidents, and solve electrical accidents.

 

Safety electricity tr--ning desk, at the same time, allow students to learn a variety of connection methods and multi -common line protection methods of the grid, such as direct contact with electric shock protection, indirect contact with electric shock protection, and safety equipment choices.

 

Safety and electricity tr--ner, a desktop modular (hanging board) structure, has strong scalability. The teaching model is installed on the hanging board, making the tr--ning components more intuitive, facilitating students to learn and master.

 

Second, equipment characteristics

 

1. Multiple, reliable and comprehensive safety protection

 

The total power switch uses reliability leakage to protect the circuit breaker. Once the leakage energy is used to cut off the power supply within 0.1 seconds; the second is that the experimental platform uses a three -phase and five -line power supply. Without touch -free experimental sockets, unaware of unconscious electric shock.

 

2. Perfect hardware configuration:

 

All kinds of power supply, instruments, loads, electronic components, circuit modules, etc. needed to the tr--ning desk together are complete together, with complete supporting facilities. Electrical control lines or electronic line components are installed on the installation board as a hanging board. It is convenient to operate and replace it with convenient replacement. It can expand other functions or develop new experiments.

 

3. Easy to expand equipment: Module structure, easy to change the hanging, facilitate the organization of various tr--ning programs and easy upgrades.

 

4. Equipment reliability: The component is connected to the terminal, the students are inserted or wiring from the terminal, and the basic skills are tr--ned to connect the theoretical theory.

 

5. Various items that can be conducted in the teaching method of electrician tr--ning projects.

Characteristic

 

This device organically combines all kinds of power, instruments, loads, simulation circuit breakers, fault setting modules and other organic ways, which are complete. Users can complete all tr--ning and assessment items without buying other accessories. The device covers a small area and saves rooms. There are voltage leakage protectors and current leakage protectors. The power supply output has monitoring and short -circuit protection functions to ensure the safety of operators and equipment. The control screen also has a timer and alarm recorder to provide unified standards for students' skill assessment.
