With the development of society, people have increasingly high requirements for the safety and reliability of electricity consumption. High voltage circuit breakers bear the dual tasks of control and protection in the power system, and their performance directly affects the safe operation of the power system. Mechanical characteristic parameters are one of the important parameters for judging the performance of circuit breakers. This instrument is based on the latest "High Voltage AC Circuit Breakers" GB1984-2003 as the design blueprint, referring to the Chinese power industry standard "General Technical Conditions for High Voltage Testing Equipment" Part 3, DL/T846.3-2004 as the design basis. It provides convenience for dynamic analysis of various circuit breakers and can accurately measure the low oil, high oil, vacuum, and Mechanical and dynamic characteristics parameters of high-voltage circuit breakers such as sulfur hexafluoride.
1. This instrument is an embedded industrial computer, with a motherboard based on CortexTM-A8, a main frequency of 1GHz, a flash memory of 1GB, and a fast startup speed of only 16 seconds. 8.4 inch color large screen, Windows operating system, user-friendly operation interface, touch screen, support for Chinese and English input, convenient for on-site operators to use.
2. High speed thermal printer, convenient for on-site printing of test data.
3. The integrated operating power supply inside the machine eliminates the need for on-site secondary power supply, making it convenient and fast to use. Can provide DC10~260V adjustable power supply with a current of 20A. Set the action voltage value of the opening and closing coils arbitrarily, and conduct low voltage action tests on the circuit breaker.
4. Equipped with linear sensors, rotary sensors, universal sensors, brackets, and dedicated fixed multifunctional connectors, the installation is extremely convenient and simple.
5. Suitable for all models of SF6 switches, GIS combination appliances, vacuum switches, and oil switches produced domestically and internationally.
6. Operate the switch once to obtain all data and graphics.
7. The host can store 30000 sets of current test data (expandable memory card), with an internal real-time clock for easy archiving.
8. Equipped with a USB drive interface, data can be directly saved to the USB drive and uploaded to the computer for analysis and saving.
9. It can simultaneously measure 12 metal contact fractures, 6 main fractures, 6 auxiliary fractures, and 3 graphite fractures.
10. Contains envelope lines, which generate standard envelope lines based on the values tested by multiple switches (2-10) for analysis and comparison, as well as for switch vibration frequency analysis.
11. The internal anti-interference circuit can meet the reliable use in a 500KV substation.
