AL505 Voltage Switch Dynamic Characteristics Testing Instrument
Implementation of standards:
DL/T 846.3-2004
Summarization
High voltage switch dynamic characteristics testing instrument is my company’s special purpose instrument designed to meet the need of testing high voltage switches . It takes the micro controller unit(MCU) for core to sample, process and then output; the main characteristic is that it’s operated in Chinese, for example ,the results are displayed and printed in Chinese. It has many advantages such as intelligence, multi-function, accurate data, strong anti-jamming, easy operation, small size, beautiful appearance, etc; It can test the switches as follows: indoors or outdoors switches with less oil or more oil, vacuum switches, SF6 switches and so on.
Major testing items and functions
1、test 12 contact’s opening time and closing time
2、test reclosing time
3、test opening simultaneity and closing simultaneity
4、test speed at instant of contacts touching (separating)
5、test springing time and springing magnitude
6、test clearance between open contacts/gaps and over travel between them.
7、test open (close) average speed
8、display and print the speed-distance curve
