12kV Withdrawable Embedded Vacuum Circuit Breaker
GPVN-12E vacuum circuit breaker is derived from German technology and is a new generation of solid-sealed vacuum circuit breaker that adopts advanced solid-sealed insulation technology.
Its main feature is that the main conductive circuit adopts a vacuum interrupter with ultra-low resistance value and conductive parts are cast in epoxy resin to achieve solid insulation, and the operating mechanism adopts a new spring mechanism with simple structure, reliable performance and optimized design.
GPVN type solid-sealed vacuum circuit breaker has passed various tests to ensure its safe operation.
Type test: power frequency withstand voltage, lightning impulse withstand voltage, short-circuit current switching, short-time and peak withstand current, temperature rise, mechanical life and other test items.
Factory test: mechanical characteristic test, main circuit power frequency withstand voltage, auxiliary and control circuit insulation test, main circuit resistance test, interlock operation test, mechanical and electrical operation test.
The technical parameters of GPVN solid-sealed vacuum circuit breaker fully comply with GB1984, GB/T11022 and DL403, and also meet the requirements of IEC62271-100, IEC56 standard and relevant standards of other major industrialized countries.
