BS EN 50152-3-1:2017EN 50152-3-1:2017 4 Introduction EN 50152-3-1 is intended for measurement, control and protection devices for specific use
24、 in a.c. traction systems other than current and voltage transformers. These are covered by EN 50152-3-2 and EN 50152-3-3 respectively. This standard covers a large variety of different kinds of equipment used in railway fixed installations which do not have railway specific product standards. It pr
25、ovides clarification on how to select ratings and test values relevant for operation in fixed installations. This standard needs to be read in conjunction with the relevant product standard of the equipment concerned. Annexes A and B are application guides. Annex A deals with railway specific measur
26、ement principles and Annex B provides guidance in the design of control systems for a.c. traction. These application guides identify characteristics of and parameters for procedures and functions used. Guidance in protection principles is given in EN 50633. The clause numbering of this part is diffe
27、rent to that used in all other parts of the series. Clause numbering in the other parts is the same as in the specific referenced product standard BS EN 50152-3-1:2017EN 50152-3-1:2017 5 1 Scope This European Standard is applicable to new low voltage devices for measurement, control and protection w
28、hich are: for indoor or outdoor fixed installations in traction systems, and operated in conjunction with high voltage equipment with an a.c. line voltage and frequency as specified in EN 50163. NOTE EN 50163 specifies the a.c. traction systems 15 kV 16,7 Hz and 25 kV 50 Hz. This European Standard a
29、lso applies to measurement, control and protective devices other than low voltage devices and not covered by a specific railway product standard as far as reasonably possible. Requirements of this document prevail. 2 Normative references The following documents, in whole or in part, are normatively

41、e thorough analysis when defining operational principles and requirements for equipment. The design of measurement, control and protection circuits, their devices and algorithms shall consider any effect arising from: fast fluctuation of traction power demand; moving tractions units, providing scena
42、rios with traction currents higher than failure currents; the return current system, especially the track, effectively connected to earth; fast fluctuation of operating voltages between Umin2 and Umax2, with Umin2 and Umax2 as specified in EN 50163; high number of switching operations e.g. caused by
43、 a high number of short circuits in the contact line systems; in 16,7 Hz traction systems the duration of a period of 60 ms in respect to magnetisation, saturation and switching times; in auto-transformer systems, a phase shift of 180 resulting in an maximum operating voltage of 2 * Umax2 but only b
44、etween phases. BS EN 50152-3-1:2017EN 50152-3-1:2017 7 NOTE 1 The return circuit in a.c. traction systems is effectively earthed. Unlike utility networks a displacement of the star point during earth faults resulting in an increase of phase voltages by factor 3 cannot happen. NOTE 2 Equipment in a 2
45、5 kV traction system is subject to a maximum permanent operating voltage phase to earth of 27,5 kV = Umax1. Equipment in a 3 phase utility network with a highest system voltage Um = 36 kV has an average continuous voltage phase to earth during 99 % of its life of 33/3 kV = 19,1 kV. If the above valu
46、es are compared, it becomes clear that the dielectric stress of equipment in traction power supply is significantly higher and therefore the test voltages e.g. during partial discharge testing have assigned higher values in this European Standard. 5 Requirements on measurement, control and protectio
47、n devices 5.1 General Measurement, control and protection devices shall be designed, manufactured and tested to their specific product standards. Requirements of railway standards prevail and shall be applied as far as reasonably possible. This especially concerns EN 50124-1 for insulation coordinat
48、ion and EN 50121-5 for electromagnetic compatibility. 5.2 Voltage detection systems Capacitive voltage detection systems shall comply with EN 61243-5 except for the following requirements: voltage absence indication shall be below 50 % of Umin2, voltage presence indication shall be above 90 % of Umi
49、n2 and the capacitive voltage detection system shall properly work also up to Umax2. NOTE 1 The thresholds for voltage absence and presence indication are adapted considering the fact that voltages are between contact line and running rail on ground potential and also the tolerances of supply voltages of traction systems. When selecting voltage detectors manufactured according to EN 61243-1 it may be preferential to use thresholds for voltage absence and presence
