Features and Advantages
1.This instrument is an embedded industrial computer, the main board is based on CortexTM-A8, the main frequency is 1GHZ, the flash memory is 1GB, and the boot speed is only 16 seconds. Large 9-inch color screen, windows operating system, intuitive user-friendly operation interface, touch screen, support Chinese and English input, which is convenient for on-site operators.
2.high-speed thermal printer, convenient for on-site printing of test data.
3.The integrated operating power supply in the machine eliminates the need for on-site secondary power supply, which is convenient and quick to use. It can provide DC6～270V adjustable power supply, current 20A. The operating voltage value of the opening and closing coil can be set arbitrarily, and the low voltage operation test of the circuit breaker can be done.
4.Equipped with linear sensor, rotation sensor, universal sensor, laser sensor (optional), bracket, special fixed multifunctional joint, installation is extremely convenient and simple.
5.Suitable for all types of SF6 switches, GIS combination electrical appliances, vacuum switches, and oil switches produced at home and abroad.
6.The switch action once, get all the data and graphics, the test data and graphics are displayed on the same screen, and the speed can be recalculated without retesting.
7.The host can store 30000 groups of current test data (expandable memory card), and the real-time clock in the machine is convenient for archiving.
8.Equipped with 2 USB ports, which can be connected to the mouse to operate the instrument, and the data can be directly saved to the U disk, uploaded to the computer for analysis and storage. RS232 interface online operation (optional), WIFI operation optional.
9.At the same time, it can measure 12 metal contact fractures, 6 main fractures and 6 auxiliary fractures, and 1 speed (optional for 3 speeds).
10.Contains the envelope curve, through the value tested by a switch, the standard envelope curve is generated for analysis and comparison, and the switch vibration frequency analysis can also be carried out.
11.The internal anti-interference circuit can satisfy the reliable use in 500KV substation.
