RVU 12-24kV VACUUM CIRCUIT BREAKER
DEFINITION
RVU Series 12-24kV Vacuum Circuit Breaker is a three-phase AC indoor breaker with 12-24kV rated voltage suitable for
air insulated switchgear and can be applied in controlling and protecting electrical equipment in industrial and mineral
enterprises, power plants and substations. Operation mechanism is installed laterally.
The product conforms to the IEC 62271-100 standard. Short circuit type tests are performed in KEMA High Power Laboratory
in the Netherlands. RVU series provide safe and reliable performance. The embedded poles of RVU have the technique of
ventilation and convection. Besides the vacuum interrupter has low resistance and high number of short circuit breaking.
AII of that reduce the power consumption and the temperature rising due to the longtime running of circuit breaker.
Under normal conditions the interrupter is in closed position.
Arcing is occured within the interrupter by withdrawing the
moving contact from stationary contact. This arc burns in the
metal vapor evaporated from local hot spots on the contact
surfaces. The metal vapour continually leaves the inter-contact
region and recondenses on the contact surfaces and surrounding
metal vapor condensation shield. The latter is usually isolated
from both contacts and serves to protect the glass or ceramic
envelope from vapor deposition. At current zero, vapor production
ceases and the original vacuum condition is rapidly approached.
The dielectric strength of the interrupter also increases, and the
circuit is interrupted.
