Circuit Breaker Analyzer

Circuit Breaker Analyzer

Model : CBA-81

Model ‘CBA-81’ is a latest state of the art micro-processor based analyzer for circuit breaker analysis. This can test all types of SF6 breakers, GIS switchgear, vacuum switches and oil breakers with metal contacts.

CBA-81 has universal speed sensor, linear travel sensor and rotation sensor, thus making installation and use very simple and convenient.

CBA-81 has a large liquid crystal screen for display. Menu in English gives prompts for carrying out the test operation. The CPU has large memory and stores several sets of ‘switch off’ and ‘switch on’ test results. A real-time clock is provided to file and record the date and specific time of test.

A built-in micro-printer of fast speed can print all the data and illustrations. For computerization, the ‘CBA-81’ has software for connection to a PC to save results in hard disk directly or to be sent to other printers. ‘CBA-81’ has strong data analysis function to effectively analyze each index and parameters of mechanical characteristics of circuit breakers.

Additionally ‘CBA-81’ also has a ‘USER-DEFINED’ program for speed, enabling the user to define different instantaneous opening speeds and instantaneous closing speeds.

Machine Feature

  • Time : Intrinsic O-C time, in-phase state and corresponding period, and phase to phase synchronization of 12 fractures.
  • Closing Resistance : Pre-contact time, pre-contact waveform and resistance of closing resistance of six breaks.
  • Reclosing : The process time of ‘C-O’, ‘O-C’, ‘O-C-O’: first opening time, first closing time, second closing time, contact time and no-current time value.
  • Bounce : Switch on bouncing time, bouncing times, bouncing process and bouncing waveform of each break: switch off rebound amplitude of each break.
  • Speed : Instantaneous opening speed and instantaneous closing speed, maximum speed, time-travel characteristics curve
  • Travel : Total travel, open distance, over travel, overshoot travel, rebound amplitude.
  • Current : ‘O-C’ current of O-C coils, current oscillogram.
  • Output Power : DC 30,250 V/20A of digitally regulated operating power supply for circuit breaker is supplied by the tester and test of low-pressure operating is completed automatically to measure the operating voltage of circuit breaker.
