23、A.4.21 Page4 EN61823:2003ELECTRICAL INSTALLATIONS FOR LIGHTING AND BEACONING OF AERODROMES AGL SERIES TRANSFORMERS 1 Scope This standard specifies the characteristics of aeronautical ground lighting series transformers (AGLST) used in aeronautical ground lighting for 6,6 A series circuits, at a serv
24、ice voltage of up to 5 kV, supplied by constant current regulators up to 30 kVA in rating. AGL series transformers provide power to airport lighting luminaires or other loads (resistive) from their secondary circuits. The AGL series transformers provide continuity of the series circuit in the event
25、of a loss of the load on the transformer, and electrical isolation between the primary circuit supplied by a constant current regulator, and the secondary circuit connected to the load under conditions defined in this standard. An AGL series transformer is be able to withstand a permanent short or o

Specifications for similar series transformers intended for any primary or secondary currents other than 6,6 A, or to supply alternative voltages, constant power, reactive loads, etc., are not included in this standard. 2 Normative references The following refer

36、 series transformer Page6 EN61823:20034 General requirements 4.1 Classification There are seven types of AGL series transformers specified in this standard, defined by their nominal power, namely 30 W, 45 W, 65 W, 100 W, 150 W, 200 W and 300 W. See Table 1 for the required characteristics. 4.2 Rated
37、 current The rated primary and secondary currents shall be 6,6 A. 4.3 Earthing AGL series transformers may be provided with or without an earthing connection. 4.4 AGL construction The AGL series transformers shall have two electrically and physically separate windings, one primary and one secondary,
38、 wound on a magnetic core. The polarity of the windings shall be such that the primary plug corresponds to the large socket of the secondary receptacle (See Annex A.). All internal electrical connections shall be permanent, e.g. by compression high-pressure crimping, high-temperature soldering, weld
39、ing, etc. The shapes of the transformers are optional provided they meet all the requirements of this standard. Sharp edges shall be avoided. The AGL series transformer including all connector leads shall be able to be inserted through the open end of a cylinder 20 cm in diameter by 25 cm long, and
40、shall easily and totally fit inside such a cylinder. The transformers shall be designed so that they may be installed and will perform to the requirements of this standard in any orientation. The AGL series transformers shall be provided with two single-conductor primary leads and a two-conductor se
41、condary lead. 4.4.1 Primary connection leads The AGL series transformers shall be connected to the AGL primary series circuit cable by two insulated, multi-stranded, copper conductors, with at least a 6 mm 2cross section, and a length measured from the transformer housing to the face of the connecto
42、r of 60 10 0 + cm. The service voltage for the leads shall be 5 kV. One lead shall have a style 2 male plug at its end. The other lead shall have a style 9 female receptacle at its end. Unless otherwise agreed between the manufacturer and supplier, the connectors shall be provided with disposable sh

The case shall be composed of material formed directly on the core and coil assembly, or by compound filling a container. The transformer shall be permanently encapsulated without cracks, holes, or in
