Wiring Method of High-Voltage Switch Characteristic Tester
High-Voltage Switch Characteristic Tester can be used for testing and measuring the mechanical characteristic parameters of high-voltage switches in power systems of various voltage levels, including vacuum, SF6, low-oil, and multi-oil types. It provides stable measurement data, convenient wiring, and simple operation, making it the most convenient tool for high-voltage switch maintenance and testing.
The instrument can automatically identify the open/close state of the contacts and prompt the corresponding close/open operation based on the reference contact state.
It can detect and indicate the connection status of 6 contacts, facilitating users to check the wiring.
The instrument can store up to 100 sets of test results.
Large-screen LCD (320×240) display, advanced gray screen, no reflection or blackout under sunlight, with graphical and Chinese menu operation prompts, user-friendly menu interface, and easy operation.
The instrument has powerful graphical analysis functions, enabling simultaneous display of waveforms and processed measurement data on the same screen, making the testing process more intuitive.
The instrument is equipped with a delay protection function that automatically cuts off the coil voltage after the circuit breaker operates, effectively protecting the circuit breaker equipment and the high-voltage switch tester.
This instrument can perform electric open/close tests and manual open/close tests.
It can perform high and low voltage tests.
