    22、g equipment Heating and melting glass equipment FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on

    23、 all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Pu

    24、blication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non- governmental organizations liaising with the IEC also participate in this preparation

    25、. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus o

    26、f opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees. 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are mad

    27、e to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transpa

    28、rently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC provides no marking procedure to indicate its approval and cannot be r

    29、endered responsible for any equipment declared to be in conformity with an IEC Publication. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members o

    30、f its technical committees and IEC National Committees for any personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any

    31、 other IEC Publications. 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable for the correct application of this publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be

    32、 the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 60519-21 has been prepared by IEC technical committee 27: Industrial electroheating equipment. This second edition cancels and replaces the first edition publish

    33、ed in 1998 and constitutes a technical revision. The significant changes with respect to the previous edition are as follows: The latest editions of IEC 60519-1:2003 and IEC 60519-2:2006 have been taken into account. Definitions have been brought into line with the second edition of IEC 60050-841:20

    34、04. This standard is to be used in conjunction with IEC 60519-2:2006. It is intended to specify particular requirements for resistance heating and melting glass equipment. This Part 21 supplements or modifies the corresponding clauses of IEC 60519-2, so as to convert it into an IEC standard. 4 60519

    35、-21 IEC:2008 Where a particular subclause of Part 2 is not mentioned in this Part 21, that subclause applies as far as is reasonable. Where this standard states “addition“, “modification“ or “replacement“, the relevant text of Part 2 is to be adapted accordingly. NOTE Subclauses and notes which are

    36、additional to those in Part 2 are numbered starting from 101. The text of this standard is based on the following documents: CDV Report on voting 27/630/CDV 27/649/RVC Full information on the voting for the approval of this standard can be found in the report on voting indicated in the above table.

    37、This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. A list of all parts of IEC 60519 series, under the general title Safety in electroheat installations, can be found on the IEC website. The committee has decided that the contents of this publication will remain unch

    38、anged until the maintenance result date indicated on the IEC web site under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. 60519-21 IEC:2008 5 SAFETY IN ELECTROHEAT INST

    39、ALLATIONS Part 21: Particular requirements for resistance heating equipment Heating and melting glass equipment 1 Scope and object Replacement: This part of IEC 60519 is applicable to indirect resistance heating equipment for the heating and melting of glass, operating in voltage bands 1 and 2. Thes

    40、e particular requirements also apply to equipment for direct resistance heating and melting of glass by means of current introduced by electrodes passing through the charge to be heated. The object of this standard is the determination of safety requirements for both indirect and direct resistance h

    41、eating equipment for the heating and melting of glass. NOTE Extraction of liquid glass or a similar material at the extraction point is part of the production process and does not constitute part of the operation of the electroheat equipment. This standard covers the safety aspects of electrical par

    42、ts also in the case when electrical heating is combined with other means of heating, for example liquid fuel heating. These requirements do not apply to equipment for direct resistance heating, where, owing to the technology used, IEC 60519-3, IEC 60519-4 and IEC 60519-8 are applicable. 2 Normative

    43、references This Clause of part 2 is applicable. 3 Terms and definitions This Clause of part 2 applies except as follows: Addition: 3.101 glass-melting furnace (indirect resistance heating) furnace in which glass is melted by means of indirect resistance heating 3.102 pot furnace melting equipment in

    44、 which the batch is melted by means of indirect electrical heating in vessels called “pots” made of a fire-proof material and placed in the furnace 3.103 filling machine machine which feeds the batch into the glass furnaces 6 60519-21 IEC:2008 3.104 extraction machine machine which extracts molten g

    45、lass from the glass furnaces 3.105 extraction point opening in the glass furnace through which molten glass is drawn off NOTE Molten glass is drawn off for example, manually by means of glassmakers tools or by means of extraction machines. In the case of pot furnaces, the extraction points also serv

    46、e as openings for the feeding or extraction of samples. 3.106 earthing electrode electrode that is installed in the glass melt and is connected to the equipotential system 4 Classification of electroheat equipment according to voltage bands This Clause of part 2 is applicable. 5 Classification of el

    47、ectroheat equipment according to frequency bands This Clause of part 2 is applicable. 6 General requirements This Clause of part 2 is applicable. 7 Isolation and switching This Clause of part 2 is applicable. 8 Connection to the supply network and internal connections This Clause of part 2 is applic

    48、able. 9 Protection against electric shock This Clause of part 2 applies except as follows: Addition: 9.2.101 Measures shall be taken in the case of directly or indirectly heated melting equipment, which provides protection against electric shock when glassmakers tools or extraction machines are subm

    49、erged in the conductive glass melt, or when the batch mixture is being fed into the glass melt. Measures of this type are for example: installation of an earthing electrode for personnel safety at the extraction point. The electrode function shall be constantly monitored. When the monitoring device shows a reaction, the glass furnace shall automatically be shut down, possibly in partial areas, or by means of
