出版：National Standards Authority of Ireland
专家解读视频
Applies to single-phase a.c. one-pole circuit-breakers designed for indoor or outdoor fixed installations for operation at frequencies of 16 2/3 Hz and 50 Hz on traction systems having a UNm above 1 kV up to 52 kV. Also applies to two-pole circuit- breakers when connected in the following manner: one pole supplying the connection to the contact line of the track, the second pole supplying the connection to the feeder cable which runs alongside the same track and is used to boost the track voltage at regular intervals in combination with autotransformers. The centre of this circuit is connected to earth. Does not address circuit-breakers with dependent manual operating mechanism.
