Artificial breakdown device of lm-2 wire and cable spark teste

  Lm-2 spark tester manual breakdown device (DC / AC general) external dimension: 43 & times; 23× 18㎝ 
Product Description:
  The artificial breakdown device of lm-2 wire and cable spark tester of flux technology (Nantong) Co
, Ltd
is the national standard gb3048 9 and gb3048 15 wire and cable spark test method specifies the special instrument used to detect the minimum sensitivity and stability of spark testing machine

It is understood that the measurement departments in many provinces and cities can not carry out the verification service for the spark tester because there is no manual breakdown device
Some departments only do the voltage verification instead of the sensitivity and stability inspection
In order to ensure the quality of wire products, it is suggested that the measurement department purchase the manual breakdown device in order to carry out the verification of the spark tester

Our factory is a professional manufacturer of spark testing machines, and the indicators of spark machines are guaranteed to reach gb3048 9 requirements of standards
At the same time, LM & mdash; Manual breakdown device of type 2 wire and cable spark tester
It is used by measurement departments and wire and cable factories in various provinces and cities

LM— Type 2 artificial breakdown device is in accordance with gb3048 9 and gb3048 15
Design and manufacture according to standard requirements
It is mainly composed of a metal needle and a metal plate
The flat plate makes relative rotation movement to the needle tip
The needle tip sweeps the flat plate once every rotation cycle
The duration of each time is 0
025s for power frequency and 0
005s for DC
When the needle tip sweeps the flat plate, the distance between them is 0
25 & plusmn; 0
05mm。
LM— Type 2 artificial breakdown instrument is designed by referring to domestic and foreign prototypes
Its biggest advantages are:
① The structure is solid and reliable, beautiful and easy to carry
② The distance between electrodes is 0
25 & plusmn; 0
05mm is easy to adjust and measure, with scale indication
③ The time for the tip of the needle to sweep over the plate is 0
025s or 0
005s, which can be guaranteed
④ It can not only test the minimum sensitivity of 600ua, but also test the stability below 25kV
⑤ Equipped with counter, 1mA ammeter and 500pf high voltage capacitor
⑥ Equipped with external switch for remote operation to improve personal safety
⑦ Easy to carry weight &; search
