I. Products Description and
Application
HTGC series High voltage switch characteristics test instrument can be used to test and measure mechanical dynamic characteristics parameters of vacuum, SF6, less oil, more oil type power system’s high voltage switch and etc. It is the most convenient tool for high voltage switch’s repairerment and test for its stable data of measurement, easy wiring and simple operation, which make it possible to carry out experiments in power stations with 500kv grade and below.
II. Features
2.1 The apparatus can automatically identify breaker status of on or off for fracture and operates accordingly with clue.
2.2 Independent fracture 6 can test and indicate connection status of fracture so that it is convenient for users to check wiring.
2.3 The device can store fifty sets of testing results.
2.4 Its big screen(320×240)LCD display is an advanced grey screen which does not reflect or black screen in sunshine. Besides, its menu interface with clues of pictures and characters menu operation is rather personal and easy to operate.
2.5 The device has powerful graphical analysis function, which makes it possible to display waveform and measured data simultaneously. Thus testing process is more self-evident.
2.6 The device contains delay and protection function, which makes it possible to cutoff coil voltage automatically after circuit breaker operates. Therefore, the circuit breaker and the testing instrument are well protected.
2.7 The device can be used to carry out electric and manual switch test.
2.8 The device can be used in experiment of low voltage and high voltage, and seek the minimum voltage or closing voltage automatically.
2.9 It can be used in reclosing experiment for parameters measurement of closing-opening, opening-closing and opening-closing-opening.
2.10 Parameter measurement of vacuum contactor (single coil) .
