13、ional Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has bee

14、n established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical stand

15、ardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for

16、 voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all

17、 such patent rights. ISO 8528-4 was prepared by Technical Committee ISO/TC 70, Internal combustion engines. This second edition cancels and replaces the first edition (ISO 8528-4:1993), which has been technically revised. ISO 8528 consists of the following parts, under the general title Reciprocatin

BS ISO 8528-4:2005 1Reciprocating internal combustion engine driven alternating current generating sets Part 4: Controlgear and switchgear 1 Scope This part of ISO 8528 specifies t

21、he criteria for controlgear and switchgear for generating sets with reciprocating internal combustion engines. It applies to Alternating Current (a.c.) generating sets driven by Reciprocating Internal Combustion (RIC) engines for land and marine use excluding generating sets used on aircraft or to p

22、ropel land vehicles and locomotives. For some specific applications (e.g. essential hospital supplies and high-rise buildings), supplementary requirements may be necessary. The provisions of this part of ISO 8528 should be regarded as a basis for establishing any supplementary requirements. For gene

23、rating sets driven by other prime movers (e.g. steam engines), this part of ISO 8528 should be regarded as a basis for establishing these requirements. 2 Normative references The following referenced documents are indispensable for the application of this document.

BS ISO 8528-4:20052 3 Other regulations and additional requirements For a.c. generating sets used on board ships and offshore installations which have to comply with rules of a classification society, the additional requirements of the classification society shall be observed. The classification s

28、ociety shall be stated by the customer prior to placing the order. For a.c. generating sets operating in non-classified equipment, any additional requirements are subject to agreement between the manufacturer and customer. If special requirements from any other regulatory authority (e.g. inspecting

29、and/or legislative authorities) have to be met, the authority name shall be stated by the customer prior to placing the order. Any additional requirements shall be subject to agreement between the manufacturer and customer. 4 General equipment requirements 4.1 Mounting Switchgear, controlgear and mo

30、nitoring equipment may be mounted on or off the generator set and in one or more cubicles. 4.2 Construction The equipment shall be constructed in accordance with the following requirements: a) for rated voltages up to 1 kV, IEC 60439-1 applies; b) for rated voltages from 1 kV to 52 kV, IEC 62271-200

31、 applies. 4.3 Operating voltage The definition of operating voltage is given in IEC 60439-1 and IEC 62271-200. 4.4 Rated frequency The operational frequency of the switchgear and controlgear shall be the same as the rated frequency of the generating set. The frequency shall lie within the limits spe

32、cified in the relevant IEC standards for the incorporated components. Unless otherwise stated, the acceptable operating limit values shall be assumed to comply with the requirements of Clause 16 of ISO 8528-5. 4.5 Rated current The rated current of the switchgear assembly shall be stated, taking int

33、o account the ratings of all components of electrical equipment in the main circuit within the assembly, their disposition and application. This current shall be carried without the temperature rise of any of its parts exceeding the limits specified in IEC 60439-1 and IEC 62271-200. If the switchgea

34、r assembly consists of multiple main circuits, derating shall be carried out, taking into account the maximum sum of the actual currents at any one time. The voltage variations during operation of the generator shall be taken into account when determining the rated current of the equipment (see 12.3

35、 of IEC 60034-1). BS ISO 8528-4:2005 34.6 Control circuit voltage A voltage of less than 250 V shall be used. The following voltages are recommended: a) for alternating current: 48 V, 110 V, 230 V, (250 V) 3) ; b) for direct current: 12 V, 24 V, 36 V, 48 V, 110 V, 125 V. NOTE Limits of control suppl

36、y variation should be taken into account to ensure correct operation of control circuit devices. 4.7 Starter battery systems If the engine is to be started electrically, heavy-duty starter batteries of adequate capacity for the duty considered shall be used and allowance made for the ambient tempera

37、ture at which they are expected to operate. Partial voltages shall not be taken from the battery unless the battery will be equalized. If the control circuitry is also connected to the starter battery, then the battery shall have sufficient capacity for reliable operation of the control equipment un

38、der all conditions, even when cranking the engine (see 4.6). For batteries which are always connected in parallel to the consumers, and which are discharged only in case of power failure or peak current demand, a static charger adapted for consumer feeding shall be used. Such a charging device shall

39、 have sufficient output to provide the control system standing load current in addition to the necessary charging current for recharging the battery within an adequate time. When the RIC engine is equipped with a mechanically driven battery-charging generator, recharging of the battery shall be exec

40、uted within a reasonable engine running time. When such a battery-charging generator is provided, the static charger may supply the control system with only a standing load current and provide an adequate float charge current. The charging equipment shall be selected so that no damage is caused to c

41、ontrol relays and solenoids connected across the battery by occasional over-voltage during charging. Starter motor cables shall be dimensioned for a total cable voltage drop, while cranking the engine, not exceeding 8 % of the nominal battery voltage. 4.8 Environmental conditions Normal service cond

42、itions are specified in IEC 60439-1 and IEC 62271-200. Where there are deviations from the normal service conditions, they shall be complied with or special agreements shall be made between the manufacturer and customer. The customer shall inform the manufacturer if such exceptional service conditio

43、ns exist. In order to establish the ambient air temperature, the heat dissipation of other equipment installed in the same room shall be considered. 4.9 Enclosure and degree of protection The enclosure shall be determined and may be selected from requirements specified in IEC 60947-1. Degrees of pro

44、tection of persons against hazardous approach to live parts should be selected from IEC 62271-200. 3) Value not specified in IEC 38:1983, IEC standard voltages.

45、incoming unit. If required, it may be extended by the mains incoming unit and the associated distribution. Typical generating set switchgear schemes are shown in Figure 1. All components incorporated in the switchgear shall be adequately rated to suit the generator set operation specified. They shal

46、l also be suitable, if required, for mains operation. Type A: Sole generating set switchgear Type B: Combined generating set/mains switchgear (preferably for parallel operation) Type C: Combined generating set switchgear with incorporated COS (preferably for standby to mains duty) Type D: Generating

49、g into account the corresponding utilization (service) category demanded (usually AC-1) 4) . If the AC-1 rating is likely to be exceeded in service, the manufacturers specified making and/or breaking capacity for the load-switching device should be considered. The customer shall specify the number of poles required according to the requirements of the local supply authority. Where the ratings of the mains supply and generating set supply ar
