适用范围：This technical report applies only to circuit-breakers with their supporting structures which arerigidly connected with the ground, and does not cover the seismic qualification of circuit-breakers inmetal enclosed switchgear.Where circuit-breakers are not ground mounted, for example in a building, conditions for applicationare subject to agreement between users and manufacturers.The seismic qualification of the circuit-breakers should take into account any auxiliary and controlequipment which is mounted on the circuit-breaker structure. If the auxiliary and control equipmentis mounted on a separate structure, it may be qualified independently.This technical report is a guide providing procedures to seismically qualify ground mounted circuitbreakers.The seismic qualification of a circuit-breaker is only performed upon request.This technical report specifies seismic severity levels and gives a choice of methods that can beapplied to demonstrate the performance of circuit-breakers for which seismic qualification isrequired.NOTE In the USA, the evaluation of the seismic qualifications for circuit breakers is conducted in accordance withIEEE 693: IEEE Recommended Practice for Seismic Design of Substations.
