1 VACUUM INTERRUPTERS

Features

1. Simplified arc quenching methodThe spiral contact assures a high arc driving efficiency.

2. Simplified construction and high qualitySince complete degassing and hermetical seal are processed in a vacuum furnace, vacuum degree can be maintained for along time.

3. No evacuation tubeSince manufacturing of vacuum interrupters using ceramicsenvelopes is done in a vacuum furnace, no evacuation tube is necessary.

4. Slim bodySince new contact materials are developed, external dimen-sions are reduced.

Major Applications

Outstanding vacuum-related manu-facturing techniques of MEIDEN has completed high preformance and high-reliability vacuum interrupters.

Vacuum InterruptersVacuum Interrupters

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.

＊Vacuum Interrupters-Structure, Feature & PerformanceVacuum 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.

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.

＊Vacuum Interrupters- Manufacturing & Quality & AssuranceAll 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.

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 5×10-4[Pa], thus a service life of VI is 20 years.

MEIDEN is manufacturing the medium voltage class VIs which matches to the various specifications in the world.

＊Vacuum Interrupters for High Voltage ClassMEIDEN 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 ArrangementMEIDEN 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.

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.

MEIDEN produces two types of electrode (Spiral & Axial Magnetic Field) and its material is pressed powder of Cr-Cu alloy.
