Usage

The mechanical dynamic characteristic tester of HV switch is based on the latest "High Voltage AC Circuit Breaker" GB1984-2003 as the design blueprint.Referring to Part 3 of the General Technical Conditions for High Voltage Testing Equipment of the Power Industry Standard of the People's Republic of China,DL/ T846.3-2004 as the design basis, according to the latest national standard JJG1120-2015, UCL2015 circuit breaker tester was upgraded.It provides convenience for dynamic analysis of all kinds of circuit breakers.It can accurately measure the mechanical and dynamic parameters of low oil, high oil, vacuum, SF6 and other HV circuit breakers of various voltage levels.The measurement data is stable and has strong anti-interference ability. It can be tested in power stations with 500 KV or below.Convenient wiring, simple operation, is the most convenient tool for HV switch overhaul test.

Feature
■·It can automatically identify the breaking and closing state to prevent misoperation.
■·Independent fracture 6 can test and indicate connection status of fracture so that it is convenient for users to check wiring.
■·It can store hundred sets of testing results
■·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.
■·It has powerful graphical analysis function, which makes it possible to display waveform and measured data simultaneously. Thus testing process is more self-evident
■·It contains delay and protection function, which makes it possible to cut off coil voltage automatically after circuit breaker operates. Therefore, the circuit breaker and the testing instrument are well protected. Independent and special switching control unit, i.e. switching or closing control unit, can be used for either switching or switching test.If one of the control circuits is broken, it will not affect the use.  
■·It can be used to carry out electric and manual switch test.
■·It can be used in experiment of low voltage and high voltage, and seek the minimum voltage or closing voltage automatically
■·It can be used in reclosing experiment for parameters measurement of closing-opening, opening-closing and opening-closing-opening
■·Parameter measurement of vacuum contactor (single coil) .
■·Fully automatic completion of circuit breaker aging test (life test).
