32、ope and object This part of IEC 62271 applies to high-voltage alternating current disconnecting circuit-breakers for operation at frequencies of 50 Hz and 60 Hz on systems having voltages of 72,5 kV and above. This standard identifies which requirements of IEC 60694, IEC 62271-100 and IEC 62271-102
33、standards are applicable. It also gives the additional requirements specific to these devices. This standard covers a circuit-breaker which, when in the open position, satisfies the requirements of both a circuit-breaker and a disconnector. As there is interaction between the requirements of the sep
34、arate functions it is necessary to consider the standardisation of requirements. This standard details the requirements for a disconnecting circuit-breaker, identifying where these differ from the separate requirements of a discrete circuit-breaker and a disconnector. NOTE For design examples of dis
35、connecting circuit-breakers, refer to Annex A. 1.2 Normative references The following referenced documents are indispensable for the application of this document.
