sf6 gas circuit breaker maintenance | TD Guardian Articles

The industry was ready for an alternative to the traditional mediums of mineral oil and/or air. Using gaz sf6 as an interrupting medium had the advantages of being inflammable as well as having high dielectric strength and exceptional thermal stability. The first generation of insulating gas circuit breakers was the lower voltage classes of 72kV and 145kV.

Sulfr hexafluoride: No Leak Too Small | TD World

The Trafag gas monitors do not have any control function on the breakers to isolate sections of the GIS; instead, they only supply both a low and low-low alarm indication. The theoretical design limit of the GIS bus and breakers is that at zero SF 6 pressure, the components' insulation systems will withstand 1.0 per unit line-to-ground voltage. Throughout the design process, this fail-safe philosophy was employed when practical.

Maintenance RequirementsPreparation Before MaintenanceMaintenance ProcedureSwitchgear SparesLubrication of Operating MechanismsTroubleshooting GuideMaintenance covers a wide range of activities, all of which are required to keep the switchgear in ready condition at all times to enable it perform its functions satisfactorily. The parts subjected to normal wear and agingneed to be serviced for ensuring full reliability of the operations. These parts may be mechanical components or electrical components. The interval at which the maintenance should be carried out depends upon the following factors: 1. The number of short-circuit interruptions 2. The switching frequency 3. The actual service time The actual conditions of use in terms of the frequency of operations, environment and severity of switching duty vary so much that it is impossible for the manufacturer to give detailed guidelines to the user concerning the frequency of maintenance. The latter components are likely to need periodic inspection and servicing only, to ensure that the equipment is free from dirt, dampness and deterioration, such as corrosion of metal work and...

Low Sulfr hexafluoride action - Electric power transmission distribution

I can say that all the dead-tank gaz sf6 breakers I've worked with (mitsubishi, siemens, abb) at the 115kV or higher level all trip themselves out on low-low gas. Avoiding this would require modifying the manufacturers wiring from what I've seen. Itkind like messing with an old oil breaker anti-pump or anti-slam scheme. You just wouldn't do it.

For this breaker size, Siemens can typically complete inspections on one to two breakers per day.
