La description
this tester use the magnetic control discharging method to test
the vacuum degree of the arc extinguish chamber. Pull the
two contactors of the vacuum switch arc extinguishing chamber for
a certain distance, impose the impulse high voltage, place the
new type magnetic exciting coil outside of the arc extinguishing
chamber, make the coil put through the large current, then
produce the synchronous impulse
magnetic field. Therefore,under the effect of the strong impulse
megnetic field and the strong electrical field, the ions in the
chamber rotate and collide with the remaining gas molecule;
the produced ion current form the rate relations the remaining
gas density i.e. vaccum degree. For various vacuum
tube types, since various structures, the ion current
is different even under the same cotactor distance, same
vacuum degreem same electrical field and magnetic field. Through
the test, the corresponding relations curves  bewteen the
vacuum degree of various vacuum tubes and the ion curren can be
defined, When the ion current is tested, the vaccum degree of a
certain type of tube can obtained by checking the ion current of
that type tube.
Feature::
It can test the vacuum degree of all various vacuum switch arc
extinguish tube
No need to dismantle vacuum bulb when testing
LCD panel, easy operation
Precise and reliable testing result
Testing record can be saved, printed and checked.
Lightweight and portable
Test method: It adopts the new type exciting winding to perform the
un-demounting measuring of vacuum switching tube.
