Summary

The VMD2 series indoor circuit-breaker is our independent developed new generation 12 kv vacuuum circuit breaker. 

Its main characters as follows: the conductance circuit is installed in an three-phase insulating sleeve ,  

its mechanism and conductance circuit adopts front and rear layout. 

And the mechanism is our deveoped new design,  with simple construction,  reliable operation,

and rich manufacturing experiences of million sets ,  

used  and learned by many high-end vacuum circuit breaker manufacturers.

Technical standard

All the technical parameters of breaker completely satisfy the Standards Of GB1984 

AC Highvoltage Breaker,  

GB/T 11022 -1999 Common Specifications For High-Voltage Switchgear And Controlgear Standards,  

China Power Sector Standards DL403.

Also meet the requirements of IEC62271-100,  IEC56 and other main industrialized country’s similar standards

Testing

VMD2 series circuit breaker have passed has passed following 

test ,  to ensure the product’s safe Operation.

Type tests : power-frequency withstand voltage tests ,  lighting impact withstand voltage tests,  ,

 temperature rising tests,  short-time withstand current tests ,  peak withstand current tests ,

short circuit breaking ability tests ,  mechanical lift tests, ect

Routine test before out of factory: mechanical performance test  ,  power-frequency withstand voltage tests of the main circuit ,  

insulating property  tests on control and auxiliary circuits ,

measurement of ther resistance of the main circuit ,

 interlock operating tests ,  mechanical operating tests,  Electrical Equipment operating tests.

Scope of application

It is universally used in power plant ,  electric network ,  metallurgy industry petrochemical industry and infrastructures,

such as airport ,  subway,  building.

VMD2 circuit breaker can be applied to control and protect cable ,  trolly wire , transformer,  

generator and capacitor bank in distribution system

Safety

VMD2  circuit breaker possesses  perfect mechanical and electric interlock equipment ,  meanwhile ,

its high reliable operating performance and mechanical life ,  

coodinated with matched switchgear cabinet , to ensure normal power distribution ,  operator and equipment’s safety.
