Vacuum Interrupters
Outstanding vacuum-related manufacturing techniques of MEIDEN has
completed high preformance and
high-reliability vacuum interrupters.
Features
1. Simplified arc quenching method
The spiral contact assures a high arc driving efficiency.
2. Simplified construction and high quality
Since complete degassing and hermetical seal are processed
in a vacuum furnace, vacuum degree can be maintained for a
long time.
3. No evacuation tube
High ability development and outstanding vacuum technology
of Meidensha Corporation (“MEIDEN”) has estabilished high
voltage vacuum interrupters. MEIDEN developed a 145kV
vacuum interrupter unit for the first time in the world.
Since manufacturing of vacuum interrupters using ceramics
envelopes is done in a vacuum furnace, no evacuation tube
is necessary.
4. Slim body
Since new contact materials are developed, external dimensions are reduced.
Major Applications
· Vacuum circuit-breakers
· Vacuum switches
· Vacuum contactors
· Transformer tap changers
· Rail line circuit-breakers
· Autoreclosers
· Special duties,
e.g. for multi-operation section switches

Vacuum Interrupters
＊Vacuum Interrupters for Medium Voltage Class
＊Vacuum Interrupters-Structure, Feature & Performance
,
Vacuum Interrupters have simple to its structure. Material of copper is used for VI s flanges. Therefore Vacuum Interrupters have
exellent on heat dissipation at load current and short circuitbreaking current.

＊Vacuum Interrupters for High Voltage Class
MEIDEN developed and commercialized 72.5kV class vacuum interrupter for the first
time in the world.
MEIDEN has successfully developed a 145kV/40kA rating and turn into production.
＊Vacuum Interrupters for Customized Arrangement
MEIDEN produces two types of electrode (Spiral & Axial Magnetic
Field) and its material is pressed powder of Cr-Cu alloy.
MEIDEN corresponds to size arrangement and review the specifications of VIs based
on requirement.
Production of prottype VIs as well as test of short circuit breaking test, etc are possible.
Spiral electrode
(Soft material)
If customer would like to have new R&D and changing for now purches VI,
MEIDEN will be possible to test at our own test laboratory for customize arrengement.
Uniform-dispersion
Cr material within Cu
＊Vacuum Interrupters- Manufacturing & Quality & Assurance
This simplified manufacturing process makes Vacuum Interrupters quality
stable. After brazing under vacuum, each Vacuum Interrupter is to be given
a constant mechanical load and then inspected its dimensional variations.
All data are automatically recorded under hgih quality control. Data
recording and pass-fail judgment are automatically carried out.
Inspection of materials supplied and process control at all stage and final
inspection of vacuum degree of each vacuum interrupter ensure for quality
assurance and a long service life.
MEIDEN applies a delivery criterion of ultra-high vacuum less than
-4
5×10 [Pa], thus a service life of VI is 20 years.

VACUUM INTERRUPTERS
VI contacts are soft and have excellent current-breaking
performance, because of their uniform-dispersion materials.
Therefore, it enable to minimize the operating energy for circuit
breakers, and it helps much compact size operating mechanism.
Spiral electrode is normally applied for economic and standard
VCB/Swichgear of midium voltage class.
MEIDEN manufactures soft electrode by using forming
equipment for powder material.
AMF electrode is applied for high voltage class and capacitor
bank. The electrode is hard and have excellent high voltage
performance.
MEIDEN is manufacturing high voltage VCB upto rated 168kV
class, and Switchgear at rated 72.5kV class.
These VCB and Switchgear are using hard material on the
vacuum interrupter, its electrode is this hard material.

Total contact force [kgf ]
All the Vacuum Interrupters assembly works are carried out in a clean room.
Each part is chemically cleaned, washed, dried, and then carried to the
clean room. Vacuum Interrupter using ceramics envelopes has high
heat-resisting characteristics.
Utilizing this advantage, degassing and hermetically sealing procsses are
simultaneously carried out in a vacuum furnace.
