Scope

This Part of GB/T 24338 specifies the electromagnetic emission and immunity
requirements for fixed power supply electronic and electrical apparatus and
systems in the railway system, including the apparatus’s power supply, the
apparatus’s own protection control circuits, as well as substations,
autotransformers, booster transformers, substation switch cabinets, local
electrical switches, and other trackside apparatus.
This Part does not apply to filters of which the operating voltage is the traction
power supply voltage (e.g., filters for harmonic suppression or power factor
compensation). Usually the filter requires a separate enclosure and access
regulations. If there is electromagnetic emission limit requirement, it will be
specified in the electronic apparatus standard.
The limits of this Standard also do not apply to telecommunications signals
intended to generate intentional emissions.
The frequency range considered in this Part is 0 GHz ~ 400 GHz. The frequency
without requirements does not need to be tested.
This Part applies to fixed power supply electronic and electrical apparatus and
systems in the railway system, including.
- Apparatus for powering the railway system in substations;
- Trackside control and rectifying apparatus, including devices for power
factor compensation;
- Power supply contact network along the track other than the current
collector and associated return conductor, including high voltage power
supply system in the substation used to convert traction voltage in railway
system;
- Trackside auxiliary power supply apparatus, including power supply to
freight marshalling stations, repair stations, and stations;
to conditional connection (GB/T 17625.2-2007, IEC 61000-3-3.2005, IDT)
