ZN63A(VS1)-24 Series of indoor Vacuum Circuit Breaker is used for indoor 24kV Switchgear, this VCB design is very popular in the world, product mature and stable and reliable, also meet the requirements of IEC62271-100. IEC56 and other main industrialized country similar standards.
Vacuum circuit breaker features:
① airtight insulation system (shell)
The airtight insulation system made of ceramic, glass or glass-ceramic is a vacuum-tight container, which is made of airtight insulating cylinder, movable end cover, fixed end cover and stainless steel bellows. In order to ensure air tightness, in addition to the strict operation of the sealing process, but also requires the material itself and the internal air permeability of small gas permeability.
② conductive system
By the fixed conductive rod, fixed arc surface, fixed contact, moving contact, moving arc surface, moving conductive rod composition. There are three contact structure: cylindrical contacts, with a spiral groove running arc surface of the transverse magnetic field contacts, vertical magnetic field contacts. At present the use of vertical magnetic field technology, such arc quenching chamber with a strong and stable arc breaking capacity.
③ shielding system
Shield is a vacuum interrupter indispensable components, and there are around the contact of the main shield, bellows shield and pressure shielding with a variety of shielding. The role of the main shield is: a arc to prevent arc generated during the arc sprayed to the insulation inside the shell, thus reducing the insulation strength of the shell. B improve the uniformity of the electric field inside the arc chamber, is conducive to reducing the local field strength, to promote the vacuum interrupter miniaturization. C condensation arc products, absorb part of the arc energy, contribute to the back-arc gap dielectric strength recovery.
