Circuit breaker mechanical characteristics tester/Circuit breaker dynamic characteristics detector
Performance characteristic
1. Sexual ability
Time interval: the inherent division and closing time of 12 fractures, the same phase and the same phase.
Re-closing gate: the process time of each fracture: one-minute time, one-closing time, two-closing time, gold short time, no current time value.
Bounce: the closing bounce time, bounce number, bounce process and bounce waveform of each break; Minutes per fracture
Brake rebound amplitude.
Speed: just minutes, just closing speed, speed, time - stroke characteristic curve.
Line length: total stroke, opening distance, overstroke, overstroke, rebound amplitude.
Current: minute, closing coil, closing current value, current waveform diagram.
Energy storage: In the setting interface of the instrument, after the voltage adjustment function is turned on, the current voltage value is displayed on the screen. The up and down keys are fine, and the left and right keys are coarse. Adjust to the required voltage, keep this interface still, open the energy storage switch, there is output.
Operating voltage: The machine provides DC20 ~ 256V/15A digital adjustable circuit breaker operating power supply, automatically complete the circuit breaker low voltage operating test, measure the operating voltage value of the circuit breaker.
peculiarity
It is suitable for the mechanical characteristic test of SF6 switch, GIS combination electrical appliance, vacuum switch and oil switch produced at home and abroad.
The anti-interference ability can also be easily tested and accurately measured when the bypass bus of 500KV substation is live.
Linear sensor, rotary sensor, easy to install, simple.
When the switch is operated once, the test data of the mechanical characteristics of the switch and the corresponding waveform diagram can be obtained.
The host can store the field test data, and the real-time clock in the machine is convenient for archiving and saving the test date and time.
Host large screen, wide temperature, direct perspective, background light LCD, Chinese display data and spectrum, LCD contrast electronic adjustment, power off memory.
Chinese menu operation, easy to use. The instrument has a built-in printer to print data and graphs in real time.

Term definition
1. The same phase and the same phase: in the same phase, the separation (closing) gate time and the difference.
2. Phase and phase at the same time: in the three phases, divide (close) the gate time and the difference.
3. Average speed: In the process of splitting (closing) the brake, 10% of the total travel of the moving contact is removed from the front and back, and 80% of the middle is taken, and the ratio of the travel and time of the moving contact movement is taken.
4. Speed: In the process of breaking (closing) brake, after the moving contact begins to move, the moving contact movement is a speed measuring unit every 10ms, until the moving contact movement stops, and several speed unit values are obtained, of which the unit speed value is the breaking (closing) brake speed.
5. Rigid (closing) speed: according to the manufacturer of the switch under test, the switch model is different, and the manufacturer defines different
6. Rigid separation (closing) speed: This tester will be included in a variety of different definition parts for users to choose.
