Circuit breaker analyzer is 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.
II. Feature :
(1) Suitable for domestic and foreign production of SF6 switch, GIS combination electrical appliances, vacuum switch, oil switch, vacuum contactor, special circuit breaker (train circuit breaker). At the same time, 12 metal contact fractures, 6 main fractures and 6 auxiliary fractures can be measured. The circuit breaker is operated once, and the data and waveform such as time, bounce number and time, speed, coil current and coil resistance are obtained. With energy storage, automatic and manual low jump test, circuit breaker life test and(lock power supply and dry contact control optional) and other functions. Equipped with high speed thermal printer, convenient to print test data on site. (2) 7 inch color screen, operating under the sun is clearly visible. Menu operation, quick test interface, one-key operation, support Chinese and English input. The 12-channel fracture status is displayed in Chinese. The time, stroke, speed and waveform are displayed on the same screen. Analyze the average velocity of the specified segment and mark it on the stroke curve for easy viewing. (3) machine integrated operation power supply, no site secondary power, easy to use. Can provide DC20 ~ 270V adjustable power supply, current 20A. Short circuit protection function. In case of short circuit, 1ms will stop the voltage and current output and emit a beep to prompt the operator to check the circuit. Unique double circuit power supply design, such as closing or breaking control circuit in one damage, with the other can also be tested. (4) equipped with linear sensor, 360 degrees without dead Angle rotation sensor, with special fixed multifunctional joint, installation is very convenient, simple. The length of the 30-1000mm linear sensor can be set arbitrarily. It only needs to be equipped with the sensor, and the instrument does not need to be returned to the factory to change the program. (5) the host can store 100 groups of test data, real-time clock in the machine, easy to archive. (6) Equipped with U disk interface and R232 interface, data saved to U disk, uploaded to the computer for analysis, saving, printing, R232 interface can be connected to the computer online operation (optional function). (7) The internal anti-interference circuit can be used reliably in 500KV substation.
