High current circuit breaker characteristic tester

1High current circuit breaker characteristic testerOverview:

The XHR-8B high-voltage switch mechanical characteristic tester is a computerized intelligent testing instrument developed for high-voltage vacuum switches. This instrument adopts microelectronics technology to quickly provide accurate and reliable measurement data, and displays all the data of the closing (opening) operation in Chinese characters and stores all the data you need. It also provides Chinese character prompts for possible faults in switches and incorrect connection of external signal lines of the instrument. The instrument is easy to operate, intuitive, and can store, view, and print Chinese characters for the measured data.
IIHigh current circuit breaker characteristic testerFunction and Features:
1. Testing function
(1) The order of opening and closing the circuit breaker should be in sequence, and one to three circuit breakers should be measured simultaneously
(2) Closing (opening) time
(3) Close (open) the switch at different times, and measure one to three fracture surfaces at the same time
(4) The bounce time of the closing contact can be measured for one to three fracture surfaces
(5) The average speed of closing (opening) the gate can be measured for any phase

(6)Storage, retrieval, and printing of required data (editable time and numbering by computer)
2. Display function
(1) All parameters in the Chinese character display test function
(2) Chinese characters display various faults (including wiring errors, refusal to open, refusal to close, incorrect opening, incorrect closing, measurement errors)
(3) Chinese characters display various test states (including closing measurement, opening measurement, etc.)
(4)Character display prompts the conduction status of A, B, C and auxiliary point N
3. Characteristics:
(1)Suitable for switch operation voltage range of ≌ 100V-300V
(2) Can automatically distinguish the type of operation (closing or opening operation) and provide Chinese character prompts
(3) The switch only needs to be operated once (closed or opened once) to obtain all the measurement data for the corresponding operation
(4) All measurement data are displayed in Chinese characters on the LCD screen, which is clear and intuitive
(5) Before measurement, the opening distance of the closing (opening) switch can be manually set
(6)Press the settings button to enter the record menu, and press the record button to store all the required data
(7) All parameters and open distance parameters in the "Test Function" item can be printed out
(8) All testing items of this instrument are strictly tested and processed according to the definitions in GB3309-89
