Structure and Function:
The 145kV SF6 Circuit Breaker features a robust design that includes a porcelain pillar structure with SF6 gas as the insulating and arc-quenching medium. The breaker is equipped with a spring operating mechanism for reliable and efficient operation. It incorporates current transformers for measurement and protection, and can be used as a contact circuit breaker and switch capacitor bank. The breaker's design ensures easy maintenance, long service life, and reliable performance in a variety of environmental conditions.
Note: The installation site should be free from fire, explosion, severe vibration, chemical corrosion, and serious pollution to ensure optimal performance and safety of the circuit breaker.
