Description:
DC circuit breaker tester set is used for mechanical characteristic test of CB action device.
Model CBT-V can test up to 6 gaps of circuit breaker simultaneously
Model CBT-V has very powerful software function, together with CBT-V hardware can test all parameters at different test methods according to IEC standard. Fully suitable for international markets.
Furthermore, Model CBT-V is on market more than 5 years, is most popular model in China. Xi’an High Voltage Apparatus Research Institute Co.,Ltd, which is most authority in the field of CB test in China, use Model CBT-V to test all CB around China.
Product Features:
-IEC standard applied for
-Up to 6 gaps of circuit breaker can be tested
-Two test mode: by the tester itself or external computer by USB interface
-With large color LCD, test curves can be displayed in different color
-DC Power Source inside for CB tested action: Open/Close of CB’s contacts, DC motor rotation for CB spring stretch.
-Universal sensor clamp, suitable for almost all CB action device.
-All test data can be printed by instrument it self or issue test report by computer software
-All data can be sorted and analyzed by date, CB serial number….
-Easy operate, automatically complete the test of single-closing, single-opening by pressing the button of test, also displaying the test result.
-Automatically identify CB position of open or close to avoid the incorrect operation
-Six CB O/C state can be carried out: single open, single close, O-θ-CO, O-θ-CO-t-CO,CO-t-CO-Selectable installing the sensor on one of the A-phase, B-phase & C-phase of gap1 or gap2
-Alternative for displacement transducer or angular displacement transducer, the former is first choice.
-Three CB C/O control modes: internal control, external control, manual operate.
-Accurately test the current peak value of opening & closing coil as well as current varying curve.
-Four kinds of travelling speed for moving contact can be defined: percentage of total travel, percentage of open distance, time ,travel
-Directly & accurately measure the contact open distance,
-Be able to test and display the gap wave form, bouncing amplitude, bounce ,over-travel,
-Be able to test circuit breaker mechanical characteristics such as asynchronism, opening & closing speed, opening & closing time.
