AL505Voltage 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 testinghigh voltage switches . It takes the micro controller unit(MCU) for core to sample, process and then output; the main characteristic is that it’soperated 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 closingsimultaneity

4、test speed at instant of contacts touching (separating)

5、test springing time and springing magnitude

6、test clearance between open contacts/gaps andover travel between them.

7、test open (close) average speed

8、display and print the speed-distance curve
