The SF6 circuit breaker is comprised of two primary components: the Interrupter Unit and the Gas System.


Safety and Maintenance of SF6 Circuit Breaker:

Ensuring the safety and maintenance of SF6 circuit breakers is crucial due to their critical role in routine switching operations and equipment protection.

Inactivity for a period of 6 months or longer necessitates the operation of the circuit breaker multiple times to confirm proper functionality and clear any accumulation of dust or foreign matter on moving parts and contacts.

While pure SF6 gas is non-toxic, its lack of oxygen means it cannot support life. Its high density, being five times that of air, implies that any leakage tends to accumulate in low-lying areas like cable trenches. Operators must be alerted to the risk of suffocation.

A blend of 20% oxygen and 80% SF6 can be safely breathed, and such mixtures have been employed in controlled laboratory experiments related to lung aerodynamics.

Arcing in SF6 produces lower fluorides of sulfur, which are both gaseous and toxic. These emissions are effectively managed and absorbed by appropriate agents like activated alumina or molecular sieves, integrated within the equipment.


Furthermore, these gases emit a pungent, unpleasant odor, providing ample warning of their presence.

As mentioned earlier, metallic fluorides in the form of fine dust are also generated during the interruption process. These fluorides can be irritants, which is why most manufacturers recommend wearing protective gear like dust masks, goggles, and plastic gloves during interrupter maintenance, although there are notable exceptions on record.

The remarkably long lifespan of SF6 circuit breaker contacts implies that, in the majority of cases, neither the contacts nor the nozzles will need replacement, mitigating maintenance concerns. However, routine assessments of the gas's acidity are necessary to ensure the absorbing agent remains active and efficient.
