High Voltage Breaker

DAYA  High Voltage Breaker Details

Vacuum interrupters form the backbone of our 3AV1 Blue portfolio. Based on more than 40 years of experience in medium-voltage range and more than 6 million delivered vacuum interrupters, Siemens Energy has introduced this proven technology to high-voltage power networks in 2010. This game-changing technology offers several advantages:

Zero CO2 or F-gas emissions

Hermetical tightness to protect from decomposition products

High switching performance without degradation

Zero maintenance (sealed for life)

Perfect for low temperatures, no liquefaction of switching mediumLow risk of breakage due to flexible sheds

DAYA High Voltage Breaker  Parameters

The main task of a circuit breaker is to interrupt fault currents and to isolate faulted parts of the system. A circuit breaker must also be able to interrupt a wide variety of other currents at system voltage such as capacitive currents, small inductive currents, and load currents. The following is required from a circuit breaker:

• In the closed position it must be a good conductor;

• In the open position it must behave as a good isolator between system parts;

 • It must be able to change from the closed to open position in a very short period of time (typically in less than 0.1 second);

• It does not cause overvoltages during switching;

• It is reliable in its operation
