High-speed circuit breaker test bench
1. The use
High-speed circuit breaker test equipment is used for comprehensive parameter measurement after high-speed circuit breakers are overhauled.
2. Main functions
1) The circuit breaker shall be tested for motion performance, logic detection, and time measurement of the speed of the main contact's closing and closing.
2) After high-speed circuit breakers are inspected and repaired, it is required to be able to complete tests such as operating characteristics, time parameters, resistance values and airtightness.
3) It can record and store data and support data query.
4) Support printing function, can print the test result out through the printer, can preview before printing at the same time, can adjust printing parameter.
5) It can give tips on errors that occur during testing and software operation.
6) It can automatically adjust the parameters according to the given voltage and wind pressure, and the adjustment precision is high.
7) There are perfect protection measures for protecting the main breaker
3. Main structural composition
The inspection platform adopts a desktop structure and is mainly composed of industrial control computers, electrical protection systems, electronic control systems, data acquisition and analysis systems, and power output systems.
