1、 Product Introduction:
MHK-HIIIThe high-voltage switch dynamic characteristic tester is a specialized instrument developed by our company to meet the needs of testing the dynamic characteristics of high-voltage switches. It uses a single machine as its core for sampling, processing, and output. Its main feature is the use of Chinese character prompts for human-machine dialogue operation, displaying results in Chinese characters and printing them out. It has the advantages of intelligence, multiple functions, accurate data, strong anti-interference ability, simple operation, small size, light weight, and beautiful appearance. It is suitable for dynamic characteristic testing of various indoor, multi oil switches, vacuum switches, and sulfur hexafluoride switches.
2、 Product features:
1. This instrument is an industrial computer.
2. The anti-interference ability, in500KVSubstation testing can also be easily conducted and accurately measured.
3. Sub graphite contact switch testing, capable of accurately testing graphite contact switches3A or6Dynamic resistance waveform, time, and synchronization of a fracture.
4. Universal speed sensor, linear travel sensor, rotation sensor, installation is extremely convenient and simple.
5. Perform one action to obtain all data and corresponding waveform diagrams for the mechanical characteristics test of the switch.
6. Used for all models produced domestically and internationallySF6SwitchGISMechanical characteristic tests for combination electrical appliances, vacuum switches, and oil switches.
7. storable1000On site opening and closing test results, real-time clock inside the machine for easy archiving and storage of test dates and times.
8. Connect to useUSave and transfer data on the disk.
9. Large screen, wide temperature range, backlight LCD, fully Chinese display of all data and spectra, LCD contrast electronic adjustment, power-off memory.
10. Single operation,Easy to use, built-in printer to quickly print all data and graphs.
11. There are andPCMachine connectedRS-232Interface and Circuit Breaker Data Analysis Management SoftwareWindowsThe Chinese version can be combined withPCMachine online operation, storing test results on the hard drive, and also outputting various types of needle, laser, or inkjet printers to print test reports, making on-site testing computerized.
12. We have developed corresponding analysis software for the definition of speed, which can be used for analysis as needed and is relatively easy to use.
