28、 POWER CONVERSION EQUIPMENT 1 Scope This International Standard is applicable to the terminal markings for the main circuits of valve device stacks and assemblies, and of integrated conversion equipment. The terminal markings refer to stacks, assemblies and equipment comprising semiconductor valve d

29、evices. NOTE 1 Terminal markings for auxiliary circuits, including gate terminals and non-integrated conversion equipment with separate manufacturing of its components and their interconnection only after installation on site, are not considered in this standard. For such equipment the relevant stan

30、dards, if any, for the individual components apply. Gate terminal markings are given in 6.3. Terminal markings for other circuits such as protective conductor are not considered in this standard. The object of this standard is to specify a logical alphanumeric marking system for the identification o

31、f the external main terminals of the main power circuits in a stack, valve device assembly or integrated conversion equipment, which is applicable for the purpose of reference in circuit diagrams, catalogues, descriptions, and information exchange and storage. In the case of stacks and assemblies, a

32、lphanumeric terminal marking systems are indicated for those converter connections which are the most important and most commonly used ones. Terminal marking systems making use of graphic symbols or identifying colours are not considered in this standard. NOTE 2 The terminals of auxiliary circuits s

33、hould be marked such that they may be clearly identified. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (inc

34、luding any amendments) applies. IEC 60050-551, International Electrotechnical Vocabulary Part 551: Power electronics IEC 60146-1-1, Semiconductor converters General requirements and line commutated converters Part 1-1: Specification of basic requirements 3 Terms and definitions For the purposes of t

35、his document, the terms and definitions given in IEC 60050-551, IEC 60146-1-1 and the following apply. 3.1 external main terminals terminals of the main power circuit of the stack, assembly or equipment to which the external power supply or the load are connected NOTE 1 In the following clauses this

36、 term is abbreviated to “terminals”. BS EN 61148:201261148 IEC:2011 7 NOTE 2 For stacks and assemblies the main power circuit is formed by the principal valve arms. 3.2 integrated conversion equipment factory-built conversion equipment the components of which are assembled, interconnected and tested

37、 in the factory thus forming a complete equipment NOTE 1 Equipment composing one or more semiconductor switches is considered to be conversion equipment. NOTE 2 For transport purpose, the equipment can be divided in several cubicles that will have to be reassembled at the site. 3.3 anode electrode c

38、apable of emitting positive charge carriers to and/or receiving negative charge carriers from the medium of lower conductivity IEC 60050-151: 2001, 151-13-02 NOTE 1 The direction of electric current is from the external circuit, through the anode, to the medium of lower conductivity. NOTE 2 In some

39、cases (e.g. electrochemical cells), the term “anode“ is applied to one or another electrode, depending on the electric operating condition of the device. In other cases (e.g. electronic tubes and semiconductor devices), the term “anode“ is assigned to a specific electrode. 3.4 cathode electrode capa

40、ble of emitting negative charge carriers to and/or receiving positive charge carriers from the medium of lower conductivity IEC 60050-151:2001, 151-13-03 NOTE 1 The direction of electric current is from the medium of lower conductivity, through the cathode, to the external circuit. NOTE 2 In some ca

41、ses (e.g. electrochemical cells), the term “cathode“ is applied to one or another electrode, depending on the electric operating condition of the device. In other cases (e.g. electronic tubes and semiconductor devices), the term “cathode“ is assigned to a specific electrode. 4 Method of identifying

42、terminals The use of alphanumeric notation should be preferred to any alternative marking, as in j). a) The marking of the terminals should be based on alphanumeric notation employing capital (upper case) roman characters and Arabic numerals. NOTE 1 It is recommended that the reference letters for d

43、.c. terminals are chosen from the first part and reference letters for a.c. terminals from the second part of the alphabet. NOTE 2 In those cases where difficulties could otherwise arise in correspondence, documents, etc., the use of small (lower case) letters, which have the same significance, is p

44、ermitted. b) Letters “I” and “O” shall not be used to prevent confusion with the numerals “1” and “0”. c) For converter connections with unchangeable polarity, “+” or “pos” may be used to the positive terminal and “” or “neg” may be used to the negative terminal. NOTE 3 In this standard, if not othe

45、rwise stated, the term “polarity” is used with respect to the direction of current flow. d) The complete notation is based on the use of combinations of alternate alphabetical and numerical character groups, each containing one or more letters and/or digits. e) Terminals with identical basic marking

46、s according to Clause 5 and Clause 6 should be distinguished by a reference number in a naturally ascending sequence according to the sequence of operation or the direction of current flow starting with 1 and following the basic terminal markings, for example X1 X2 X3, Y1 Y2 Y3. BS EN 61148:2012 8 6

47、1148 IEC:2011 f) Terminals with identical basic markings according to Clause 5 and Clause 6 in two or more similar terminal groups should be distinguished by a reference number in a naturally ascending sequence starting with 1 and preceding the basic terminal markings, for example 1X 1Y 1Z, 2X 2Y 2Z

48、, etc. g) If, for further differentiation of terminal groups, further letters or numbers are required in addition to the terminal marking in Clause 5 and Clause 6 and in f), such additional marking should be placed before this marking, separated from it by a full stop. h) The marking shall be clearl

49、y legible and durable. i) The marking of the main terminals according to Clause 5 to Clause 6 shall be shown clearly on the corresponding circuit diagram. This shall also be observed for main and auxiliary terminals not considered in this standard. j) In cases where the construction mode or size of a stack or assembly prevents the application of the alphanumeric notation for terminal marking, the terminals shall be clearly identified by anot
