Power system microcomputer line protection training device

 

This device adopts a microcomputer line protection device widely used in modern power engineering, equipped with modules such as power supply, two sections of transmission lines, intestines, and intelligent fault settings. This device m--nly completes the tr--ning of the characteristics of the protection of the characteristics of the protection device, the wiring, the settings, and the operation. It can be used for tr--ning in the power industry, and it can also be used for the assessment of the tr--ning of students related to high school and technical technical schools.

 

1. Smart fault settings and large screen LCD answers:

 

2. Operation unit: operating unit circuit board (integrated with display), keyboard.

 

3. The operating unit adopts multiple protection design; dual -power DC 12V input; 128x64LCD display; 8th road switch to the alarm input, *** more 48 relay control; the operating unit can not be connected to the Internet; Display prompts.

 

There are m--nly the following operating functions:

 

Student entrance: Students can be used when the students are lifted, and they can inquire about the rem--ning time of the assessment.

 

Teacher entrance: Set up faults, to remove all f--lures, set the assessment time, modify the login password, and set the device number. Teachers need to log in to the password.

 

Score query: query the current scoring of students.

 

Learning number query: Query the teacher set by the teacher through the computer.

 

Equipment number query: query the device address of this machine, each operating unit has a ** device address.

 

The assessment time starts: After the teacher setting the assessment time, the assessment starts to count the countdown.
