2、 Performance characteristics

2.1 Performance

ltimeBetween:12The inherent opening and closing time of each fracture, in phase synchronization and phase synchronization.

lClosing resistor: The pre switching time, pre switching waveform, and resistance value of the closing resistor on the fracture surface.

lweightcloseLock: The closing closing time (gold short time) and opening closing time (no current time) of each break, and the opening closing opening time: one opening time, one closing time, and two opening time.

lballJump: The closing bounce time, bounce frequency, bounce process, and bounce waveform of each fracture.

lfastDegree: rigid opening and closing speed, maximum speed, time stroke characteristic curve; Recloser speed of one minute, one minute closing speed, and two minute closing speed.

lgoCheng: Total travel, opening distance, overtravel, overshoot, rebound amplitude.

lelectricityFlow: The current values and waveform diagrams of the opening and closing coils.

lAction voltage: Provided internallyDC30～250V/20A(Instantaneous operation) The digital adjustable circuit breaker action power supply automatically completes the low voltage action test of the circuit breaker and measures the action voltage value of the circuit breaker.

2.2 Characteristics

uSuper strong industrial computer design, anti-interference ability, in500kVSubstation testing can also be easily conducted and accurately measured.

uUniversal speed sensor, linear travel sensor, rotation sensor, installation is extremely convenient and simple.

uOnce the switch is activated, all data and corresponding waveform diagrams of the switch mechanical characteristic test are obtained.

uApplicable to all models produced domestically and internationallySF₆SwitchGISMechanical characteristic tests for combination electrical appliances, vacuum switches, and oil switches.

uHost can store1000On site opening and closing test results, real-time clock inside the machine for easy archiving and storage of test dates and times.

uCan be used directlyUSave and transfer data on the disk.

uThe host has a large screen, wide temperature range, background light LCD, full Chinese display of all data and maps, LCD contrast electronic adjustment, and power-off memory.

uChinese menu operation,Easy to use, built-in printer to quickly print all data and graphs.

uThe instrument is equipped with andPCMachine connectedRS-232Interface and Circuit Breaker Data Analysis Management SoftwareWindowsThe Chinese version can be combined withPCMachine online operation, the test results can be directly stored in the hard drive, and can also be output to various needle, laser, or inkjet printers to print test reports, making on-site testing computerized.

Corresponding analysis software has been developed to define the speed of just opening and just closing, which can be used for speed measurement of any type of switch produced by any switch factory at home and abroad according to needs.
