IEC 61992-3:2001 轨道交通.固定设施.直流开关设备.第3部分:户内隔离器及隔离器式开关

This part of IEC 61992 specifies requirements for d.c. disconnectors, switch disconnectors and earthing switches for use in indoor fixed installations of traction systems. NOTE 1 Switchgear assemblies, electromagnetic compatibility (EMC) and dependability are not covered in this part of IEC 61992, but rather by other parts of this standard or other standards as indicated in IEC 61992-1. NOTE 2 In this standard, the word "unit" means "disconnector and/or switch disconnector and/or earthing switch" as defined in 3.1.4, 3.1.5 and 3.1.6 of IEC 61992-1. NOTE 3 Disconnectors, switch disconnectors and earthing switches may have electrically latched mechanisms and, in such cases, may be indicated with the current term of "power contactors".

IEC 61992-1:2001 轨道交通.固定设施.直流开关设备.第1部分:总则

The IEC 61992 series specifies requirements for d.c. switchgear and controlgear and is intended to be used in fixed electrical installations with nominal voltage not exceeding 3 000 V d.c, which supply electrical power to vehicles for public guided transport, i.e. railway vehicles, tramway vehicles, underground vehicles and trolley-buses.

This part of IEC 61992 specifies requirements for d.c. circuit-breakers for use in fixed installations of traction systems. NOTE Switchgear assemblies, electromagnetic compatibility (EMC) and dependability are not covered in this part of IEC 61992, but by other parts of this standard or by other standards, as indicated in IEC 61992-1.

To be read in conjunction with BS EN 60129:1994

Railway applications - Fixed installations - Particular requirements for a.c. switchgear - Single-phase disconnectors, earthing switches and switches with Um above 1 kV

BS EN 50152-1:1999 轨道交通.固定装置.交流开关专门要求.电压大于1KV的单相电路断路器

EN 50152-1 is applicable 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 an UNm above 1 kV up to 52 kV. EN 50152-1 is also applicable 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 which is used to boost the track voltage at regular intervals in combination with autotransformers. The centre of this circuit is connected to earth. This standard is also applicable to the operating devices of circuit-breakers and to their auxiliary equipment. This standard does not address circuit-breakers with dependent manual operating mechanism. NOTE A rated short-circuit making current cannot be specified for these circuit-breakers and the use of these mechanisms may give reasons for the objection based on their safety in operation.
