one,
The switch features a tester, which is a newly designed special instrument for detecting the mechanical characteristics of high-voltage circuit breakers.The instrument uses high-tech technology, which integrates computer, printer, measuring interface circuit, operating power is equal, is the new high-voltage circuit breaker detection The instrument is equipped with two kinds of displacement sensors which are suitable for different distance and precision test. The automatic identification system is used to identify the selected sensors, and the sensors are replaced with less oil, oil, sulfur hexafluoride, vacuum and high voltage In the design of the instrument, only one time (minute) action that can be six full of data sampling data recorded, with a single key operation to display the measurement results, and can print records of measurement data, print six The current waveform of the fracture and the dynamic characteristics of the contact time of a fracture. The instrument is designed in strict accordance with the definition of the international 'GB1984-9' and 'GB3309-9'.

2, the main performance and characteristics of the instrument
(1) The instrument uses a high stability device. Floating, in the area, digital filtering and other anti-jamming technology.
(2) The instrument is equipped with two kinds of displacement sensors, suitable for different distance distance, speed, accuracy requirements of high-voltage circuit breakers to detect, after the insertion of different sensors, the instrument will automatically identify the instrument on the high-voltage circuit breaker (sub) Gate operation, reclosing operation can be automatically identified. After the operation of all the various data automatically collected. Measurement calculation process by the computer to complete the maneuver.
(3) the instrument on the high-voltage circuit breaker in the measurement of wiring errors, as well as the operation of the wrong instructions and unsuccessful operation, with automatic recognition and strong self-protection function.
(4) the instrument pair (sub) gate order and the actual joint (sub) gate time are to be displayed on the maintenance, commissioning high-voltage circuit breaker three-phase different period, with the same period to provide the basis for the relevant time The amount of data, with 0.1 milliseconds of data automatically do not show the output.
(5) the instrument on the dynamic contact of the trip, over the trip measurement, as long as the high-voltage circuit breaker in any one phase of the installation of the sensor on the junction, that can be three-phase fracture of the trip, super-stroke data measurement calculated, The accuracy of the measurement is 1% of the meter.
(6) The power supply box provides 0-250 V AC and DC operation power to operate directly on the high voltage circuit breaker, and is suitable for operation such as electromagnetic, hydraulic and spring energy storage.
(7) instrument small size, light weight, simple operation, easy to carry, especially for field flow detection and substation site maintenance test, high voltage circuit breaker production, inspection, maintenance, commissioning of the necessary tools.
