ZC-300B circuit breaker analyzer can be used to test and measure the mechanical characteristic parameters of high voltage switch ( such as vacuum, six fluoride, less oil, oil and other power systems. The measurement data is stable, strong anti-interference ability, can be in the 500KV level and below the power station to do experiments, wiring is convenient, simple operation, is the most convenient tool for high-voltage switch maintenance test.
The instrument can automatically identify the fracture opening and closing state, and according to the reference state corresponding to the fracture tip and operation.
Independent 12 fracture, can detect and indicate the connection state of the fracture, facilitate the user to check the wiring
The tester can store 50 groups of test results.
Large screen LCD (320 * 240) LCD display, advanced gray screen, without reflection or black in the sun, and English characters graphic menu.
Operation tips, user-friendly menu interface, easy to operate.
The instrument has powerful function of graphic analysis, and the waveform and measurement data are displayed on the same screen.
The utility model has the function of time delay protection, and the coil voltage can be automatically cut off after the circuit breaker is operated.
The instrument can be divided into electric and manual test.
For high and low voltage test, automatically find the lowest open or closing voltage.
Reclosing test, can do parameters test for open-closing, closing-open and open-closing-open etc.
