Digital High Voltage Circuit Breaker Analyzer Hv Switch Dynamic Characteric Tester

XHJJ302A High voltage circuit breaker analyzer

1. It is suitable for SF6 switches, GIS combined electrical appliances, vacuum switches, oil switches, vacuum contactors, special circuit breakers (train circuit breakers) produced at home and abroad. At the same time, it can measure 12 metal contact fractures, 6 main fractures and 6 auxiliary fractures. When the circuit breaker operates once, data and waveforms such as time, bounce times, time, speed, coil current and coil resistance are obtained. It has functions such as energy storage, automatic and manual low-jump test, circuit breaker life test and (optional for blocking power supply and dry contact control). Equipped with a high-speed thermal printer, it is convenient to print test data on site.
2. 7-inch color highlight screen (brightness can be adjusted), the operation under the sun is also clearly visible. Menu operation, quick test interface, one-key operation, support Chinese and English input. 12-channel fracture status display in Chinese, time, travel, speed and waveform are displayed on the same screen, no need to turn pages to view data. Analyze the average speed of the specified segment and mark it on the stroke curve for easy viewing. Built-in 21 conventional types of circuit breaker speed definitions, just select the switch type and measure with one key.
3. The integrated operating power supply in the machine does not require on-site secondary power supply, which is convenient and quick to use. Can provide DC20 ~ 270V adjustable power supply, current 20A. It has the function of short-circuit protection. If a short-circuit occurs, the voltage and current output will be stopped within 1ms, and a drip alarm will sound, prompting the operator to check the line. Unique dual-circuit power supply design, if one of the closing or opening control circuits is damaged, the other circuit can also be used to test closing and opening.
4. Equipped with linear sensor, rotary sensor, with special fixed multi-function joint, the installation is extremely convenient and simple. The linear sensor can be set arbitrarily in the length of 30-1000mm, only need to match the sensor, the instrument does not need to be returned to the factory to change the program.
5. The host can store 100 groups of current test data, the real-time clock in the machine, easy to archive.
6. Equipped with U disk interface and R232 interface, data is saved to U disk, uploaded to the computer for analysis, storage, printing, R232 interface can be connected to the computer for online operation (optional function).
7. The internal anti-interference circuit can meet the reliable use in 500KV substation.
