30、) 1995-03-01 EN 60255-6:1994 BSI 03-19993 Section 1. General 1 Scope and object This standard specifies the general performance requirements of all electrical measuring relays and protection equipment used in the electrotechnical fields covered by the IEC. It excludes relays used in the following el
31、ectrotechnical fields: telephony; telegraphy; signalling and blocking in railway systems; devices covered by IEC Publications 158, 292 and 337. For special applications (marine, aerospace, explosive atmospheres, computers, etc.), it may be amplified by means of special requirements. Relays which are
32、 designed to meet the requirements prepared by other international standardization organizations (telecommunication, railways, etc.) shall comply with this standard when used in the electrotechnical fields covered by the IEC, other than those excluded above. The requirements are applicable only to r
33、elays in new condition. All tests in this standard are type tests unless otherwise declared. The object of this standard is to state: 1) definitions of terms used; 2) nominal values relating to energizing and influencing quantities; 3) requirements related to accuracy, thermal and mechanical perform
34、ance; 4) test methods; 5) markings and data. 2 Definitions For definitions of general terms not defined in this standard, reference should be made to the International Electrotechnical Vocabulary (IEV) IEC Publication 50 and first level documents of the IEC Publication 255 series. For the purpose of
35、 this standard the following definitions shall apply. 2.1 single input measuring relay a relay which is designed to respond to a single input energizing quantity and where the measuring function is determined by a single energizing quantity NOTEIf single input measuring elements of the same type are
36、 packaged as protection equipment, e.g. 3-phase overcurrent relays, they are to be considered as single input measuring relays. 2.2 multi input measuring relay a relay which is designed to respond to more than one input energizing quantity and where the measuring function is determined by the intera
37、ction of the energizing quantities 2.3 dependent time relay with increasing function a dependent time relay whose operating time increases in accordance with an increase of the characteristic quantity 2.4 dependent time relay with decreasing function a dependent time relay whose operating time decre
38、ases in accordance with an increase of the characteristic quantity Section 2. Requirements 3 Standard values 3.1 Input energizing quantities 3.1.1 General No standard values of input energizing quantities are specified. Those given below are preferred values, of which those underlined have found gre
39、ater acceptance and are expected to become standard values in the future. 3.1.2 Primary relays No preferred rated values for a.c. or d.c. 3.1.3 Secondary relays a) A.C. voltages (r.m.s.) The preferred rated values of voltages for a.c. are those given below, together with those values multiplied by 3
40、, or 1/3. For single phase railway systems multiply 100 V and 110 V by 0.5. 100 V; 110 V; 115 V; 120 V; 200 V; 220 V, 240 V; 480 V. b) A.C. currents (r.m.s.) The preferred rated values of currents for a.c. are given below: 0.5 A; 1 A; 2 A; 5 A. 3.1.4 Shunt (energized) relays The preferred rated valu
41、es of d.c. voltages are given below: 30 mV; 45 mV; 50 mV; 60 mV; 75 mV; 100mV; 150 mV; 200 mV; 300 mV; 600 mV. EN 60255-6:1994 4 BSI 03-1999 3.2 Auxiliary energizing quantities The rated values shall be selected from the following: 3.2.1 General No standard values for auxiliary energizing quantities
42、 are specified. Those given below are preferred values, of which those underlined have found greater acceptance and are expected to become standard values in the future. 3.2.2 A. C. voltages (r.m.s.) 24 V; 48 V; 100/3 V; 110/3 V; 120/3 V; 100 V; 110 V; 115 V; 120 V; 133 V; 200 V; 230 V; 415/3 V; 400
43、 V; 415 V; 480 V; 500 V; 660 V. 3.2.3 A.C. current There are no preferred rated values for a.c. currents. 3.2.4 D.C. voltage 12 V; 24 V; 48 V; 60 V; 110 V; 125 V; 220 V; 250 V; 440 V. 3.2.5 D.C. current There are no preferred rated values for d.c. current. 3.2.6 Operative ranges of auxiliary energiz
44、ing quantities The limits of the operative range for each auxiliary energizing quantity shall be as specified in lower level documents. Rated values of non-preferred ranges shall be distinguished from the values of the limits of the operative range by suitable means, for example by underlining, or b
45、y use of a special type face. The values shall be marked on the relay. Examples are shown in Table I. 3.2.7 Preferred operative range of auxiliary energizing quantities The limits of the preferred operative range are 80 % 110 % of the rated value. For d.c. these values are mean values. For permitted
46、 peak-ripple factor see Table II (Note 6). For a.c. auxiliary energizing quantities, in special cases, for example frequency measuring relays, the auxiliary energizing quantities may require larger limits. NOTEIn some circumstances, particularly in the case of energization from certain storage batte
47、ries, the limits of the operative range may necessarily differ from the preferred value. In these circumstances the manufacturer shall declare the limits of the range and the corresponding rated value. 3.3 Frequency The standard rated values of frequency shall be selected from the following: 16 50 H
48、z; 60 Hz 3.4 Values of resetting and disengaging ratios To be specified in lower level documents. 3.5 Contact circuits The standard values of voltages and currents for contact circuits shall be taken from IEC Publication 255-0-20:1974. 3.6 Independent specified times There are no rated values for in
49、dependent specified times; however, in the case of relays having a time-setting range, maximum values are proposed in Appendix A. 3.7 Standard reference values of influencing quantities and factors and standard values of their nominal and extreme ranges 3.7.1 Standard reference values of influencing quantities and factors The standard reference values of influencing quantities and factors and the associated test tolerances are given in Table II. The manufacturer shall declare the effects of self heating of relays mounted as in normal
