1、BRITISH STANDARD BS EN 61071-1:1997 Power electronic capacitors Part 1: General The European Standard EN 61071-1:1996 has the status of a British Standard ICS 31.060.70 Licensed Copy: sheffieldun sheffieldun, na, Fri Nov 10 16:40:40 GMT+00:00 2006, Uncontrolled Copy, (c) BSI BS EN 61071-1:1997 This
2、British Standard, having been prepared under the direction of the Electrotechnical Sector Board, was published under the authority of the Standards Board and comes into effect on 15 October 1997 BSI 03-2000 ISBN 0 580 28459 X National foreword This British Standard is the English language version of
3、 EN 61071-1:1996. It was derived by CENELEC from IEC 61071-1:1991. The CENELEC common modifications have been implemented at the appropriate places in the text and are indicated by a side line in the margin. From 1 January 1997, all IEC publications have the number 60000 added to the old number. For
4、 instance, IEC 27-1 has been renumbered as IEC 60027-1. For a period of time during the change over from one numbering system to the other, publications may contain identifiers from both systems. The UK participation in its preparation was entrusted to Technical Committee PEL/33, Power capacitors, w
5、hich has the responsibility to: aid enquirers to understand the text; present to the responsible international/European committee any enquiries on the interpretation, or proposals for change, and keep the UK interests informed; monitor related international and European developments and promulgate t

Cross-references Attention is drawn to the fact that CEN and CENELEC Standards normally include an annex which lists normative references to international publications with their corresp
7、onding European publications. The British Standards which implement these international or European publications may be found in the BSI Standards Catalogue under the section entitled “International Standards Correspondence Index” or by using the “Find” facility of the BSI Standards Electronic Catal

General 1.1 Scope and object This part of IEC 1071 applies to capacitors intended to be used in power electronic equipment, particularly for: semiconductor switc
30、hing and protection, filtering and energy storage. The rated voltage of capacitors covered by this part is limited to 10 000 V. The operating frequency of the systems in which these capacitors are used is usually below 1 000 Hz, while the pulse frequencies may go up to several 1 000 Hz in some cases
31、 beyond 10 000 Hz. It distinguishes between a.c. capacitors and d.c. capacitors. They are considered as components mounted in enclosures. Capacitors within the scope of this part include those capacitors intended for use in power electronic equipment such as: Semiconductor converters according to IE
32、C 146 or IEC 411. NOTE 1The following are excluded from this part: Capacitors for induction heat-generating plants operating at frequencies between 40 and 24 000 Hz (IEC 110). Capacitors for motor applications and the like (IEC 252). Capacitors to be used in circuits for blocking one or more harmoni
33、cs in power supply networks. Small a.c. capacitors as used for fluorescent and discharge lamps (IEC 566). Capacitors for suppression of radio interference (IEC 384-14). Shunt capacitors for a.c. power systems having a rated voltage above 1 000 V (IEC 871-1, 2). Shunt power capacitors of the self-hea
34、ling type for a.c. systems having a rated voltage up to and including 1 000 V (IEC 831-1, 2). Shunt power capacitors of the non self-healing type for a.c. systems having a rated voltage up to and including 1 000 V (IEC 931-1, 2). Electronic capacitors not used in power circuits, (IEC 80 and IEC 166)
35、. Series capacitors for power systems (IEC 143). Coupling capacitors and capacitor dividers (IEC 358). Capacitors for applications requiring energy storage/high current discharge such as photocopiers and lasers. Capacitors for microwave ovens. NOTE 2Additional requirements for capacitors to be prote
36、cted by internal fuses and internal disconnecting devices, as well as requirements for self-healing tests, endurance tests and destruction tests are under consideration. NOTE 3This standard covers an extremely wide range of capacitor technologies for numerous applications. Examples are given in sect
37、ion 6. The object of this standard is: a) to formulate uniform rules regarding performances, testing and rating; b) to formulate specific safety rules; c) to provide a guide for installation and operation. 1.2 Normative references The following standards contain provisions which, through reference i
