NRGK-G Circuit Breaker Analyzer is applied to measure the opening and closing time of all types of circuit breaker, such as vacuum interrupter, SF6 switch, GIS composite apparatus, oil breaker. It has strong anti-interference capability, can easily test and accurately measure in the case of a 500kV substation bypass bus. It is adopted a common speed sensor, linear sensor and a rotation sensor, the installation is very easy and simple.
Overview
Product Performance
● Time: the inherent switching on and off time of 12 channels same-phase synchronization phase to phase is simultaneous.
● Reclosing: each channel of circuit breaker analyzer: open-close close-open open-close-open; Processing time: one open time a close time two close time gold short time no current time value
● Bouncing: Every channel with closing bounce time bouncing times bouncing process bouncing waveform; each channel with opening bouncing amplitude
● Speed: just now just close speed maximum speed time - trip characteristic curve
● Stroke: total stroke opening distance over stroke overshoot stroke bounce amplitude
● Current: opening & closing coil current value of opening & closing current waveform
● Active voltage: the tester provides DC30 ~ 250V/20A a digital adjustable power circuit breaker as the active power supply complete low-voltage active testing of circuit breakers automatically measure the active voltage value of the circuit breaker
● With strong anti-interference capability it can easily test and accurately measure in the case of a 500kV substation inter-bus charged.
● Universal speed sensor linear sensors rotary sensors extremely easy to install.
● Switching acted for one time can get all the data of switch mechanical characteries tests and the corresponding waveform patterns.
● Can store the field test data. The inside real-time clock is facilitated to save test date and time.
● Host with big screen wide temperature direct perspective background light LCD display all data and waveform in English electronic LCD contrast adjustment with power of memory.
● English menu operation easy to use. Instrument with a built-in printer can quick print all data and waveform at any time
