BS EN 50645:2017EN 50645:2017 4 1 Scope This European Standard gives Ecodesign requirements for small power transformers comply
22、ing with the EN 61558 series and in relation to Commission Regulation (EU) N 548/2014 implementing the European Directive 2009/125/EC. This European Standard is applicable to transformers with 50 Hz AC input and output with a rated power of 1 kVA or more and a voltage lower than 1 kV, except those e
23、xcluded in the regulation. For transformers with a voltage between 1 kV and 1,1 kV, this standard may be used as a guide. 2 Normative references Not applicable. 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. NOTE Unless otherwise specified, the
24、terms “voltage” and “current” imply the r.m.s. values of alternating voltage and current. 3.1 (power) transformer static piece of apparatus with two or more windings which, by electromagnetic induction, transforms a system of alternating voltage and current into another system of voltage and current
25、 usually of different values and at the same frequency for the purpose of transmitting electrical power SOURCE: IEV 421-01-01 Note 1 to entry: The term frequency also implies that the waveform remains the same. 3.2 short-circuit voltage voltage to be applied to the input winding, when the windings a
26、re at ambient temperature, to produce in the short-circuited output winding a current equal to the rated output current Note 1 to entry: The short-circuit voltage is usually expressed as a percentage of the rated supply voltage. 3.3 rated output current output current at rated supply voltage, rated
27、supply frequency and rated output voltage, at rated power factor, assigned to the transformer by the manufacturer for the specified operating conditions of the transformer 3.4 rated supply voltage supply voltage (for polyphase supply, the phase-to-phase voltage) assigned to the transformer by the ma
28、nufacturer for the specified operating conditions of the transformer 3.5 rated output voltage output voltage (for polyphase supply, the phase-to-phase voltage) at rated supply voltage, rated supply frequency and rated output current, at rated power factor, assigned to the transformer by the manufact
29、urer for the specified operating conditions of the transformer BS EN 50645:2017EN 50645:2017 5 3.6 rated power factor power factor assigned to the transformer by the manufacturer for the specified operating conditions of the transformer 3.7 input circuit circuit intended to be connected to the suppl
30、y consisting of the input winding and the internal circuits 3.8 output circuit circuit to which the distribution circuit, appliance or other equipment is to be connected, consisting of the output winding and the internal circuits 3.9 internal circuit circuit which consists of components, interconnec
31、tions and connections to the terminals and the windings, excluding protective earth circuit 3.10 input winding winding of the input circuit 3.11 output winding winding of the output circuit 3.12 rated supply frequency frequency on the input of the transformer assigned by the manufacturer Note 1 to e
32、ntry: The supply frequency is the frequency of the mains. 3.13 load loss (Pk) active power absorbed by the transformer when supplied with its short-circuit voltage, its secondary windings being short-circuited 3.14 rated power (Sr) (or rated output) product of the rated output voltage and the rated
33、output current or, for three-phase transformers, 3 times the product of the rated output voltage and the rated output current; if the transformer has more than one output winding or a tapped output winding, the rated output denotes the maximum sum of the products of rated output voltage and rated ou
34、tput current for output circuits intended to be loaded simultaneously 3.15 no-load loss (P0) active power absorbed by the transformer when supplied with its rated supply voltage at rated supply frequency, with no load on the output 3.16 rated ambient temperature (ta) maximum temperature at which the
35、 transformer may be operated continuously under normal conditions of use Note 1 to entry: The value of the rated ambient temperature (ta) does not preclude temporary operation of the transformer at a temperature not exceeding (ta + 10) C. BS EN 50645:2017EN 50645:2017 6 4 General notes on tests Test
36、s according to this European Standard are: type tests (defined in Clauses 6 and 7); routine tests (defined in Annex A). Each sample transformer shall comply with all the relevant tests. Tests are carried out on specimens as delivered. Transformers designed for more than one rated supply voltage are
37、tested with the maximum rated power at the lower supply voltage. 5 Marking and other information 5.1 The transformers shall be marked on rating plate with the values for: a) rated power; b) load loss; c) no-load loss; d) electrical power of any cooling system required at no load operation; e) weight
38、 and nature of conductors; f) weight and nature of core material. 5.2 The information listed in 5.1, the manufacturers name and address, and the model identifier (type reference) of the transformers shall be marked in the technical documentation if it exists. 6 No-load loss (Po) 6.1 When the transfo
39、rmer is connected to the rated supply voltage, at the rated supply frequency, with no load on the output, the no-load loss shall not be higher by more than 5 % from the marked value. NOTE 1 The ratio is defined as follows: PPP0 marked100 %0 measured0 markedNOTE 2 The value of 5 % corresponds to the
40、“verification tolerances” specified in the regulation. Compliance is checked by measuring the no-load loss at ambient temperature. 6.2 The electrical power of any cooling system required at no load shall not be higher by more than 5 % from the declared value. NOTE The value of 5 % corresponds to the
41、 “verification tolerances” specified in the regulation. BS EN 50645:2017EN 50645:2017 7 7 Load loss (Pk) The load loss shall not be higher by more than 5 % from the marked value. NOTE 1 The ratio is defined as follows: PPPk marked100 %k measuredk markedNOTE 2 The value of 5 % corresponds to the “ver
42、ification tolerances” specified in the regulation. Compliance is checked as follows: the active power consumed by the transformer shall be measured when steady-state conditions are established at its rated ambient temperature ta or 25 C, the transformer being supplied with its short-circuit voltage
43、and the secondary windings being short-circuited. BS EN 50645:2017EN 50645:2017 8 Annex A (normative) Routine tests (production tests) The no-load loss shall be checked as indicated in 6.1.
