High Voltage Circuit Breaker

DAYA  High Voltage Circuit Breaker Details

The core of our 3AV1 Blue portfolio is constituted by vacuum interrupters. Leveraging over 40 years of expertise in the medium-voltage segment and having delivered more than 6 million vacuum interrupters, Siemens Energy introduced this tried-and-tested technology to high-voltage power networks in 2010. This revolutionary technology boasts several compelling benefits:

It generates zero CO2 or F-gas emissions.

It maintains hermetical tightness, safeguarding against decomposition products.

It provides superior switching performance without any degradation.

It requires zero maintenance, being sealed for its lifetime.

It functions perfectly in low temperatures, eliminating the risk of liquefaction of the switching medium.

Additionally, it has a low risk of breakage due to its flexible sheds.

DAYA High Voltage Circuit Breaker  Parameters

The essential function of a circuit breaker is to promptly sever fault currents and isolate faulty sections of the system. Additionally, it must effectively handle diverse currents, including capacitive, small inductive, and load currents, at system voltage. The key requirements for a circuit breaker are:

• It must exhibit excellent conductivity when in the closed state;

• It must effectively isolate system components when in the open state;

• It must possess the capability to transition from closed to open in a swift manner, often within 0.1 second;

• It should not induce overvoltages during the switching process;

• It must operate reliably and consistently.
