13、tional Electrotechnical Commission IEC 34-1, (EN 60034).- the recommendations of the International Standards Organisation ISO 8528.- the European Community directive 89/336/EEC on Electromagnetic Compatibility (EMC).- the European Community directives 73/23/EEC and93/68/EEC (Low Voltage Directive).T

14、hey are CE marked with regard to the LVD (Low Voltage Directive) in their role as a machine component. A declaration of incorporation can be supplied on request.Before using your generator for the first time, read carefully the contents of this installation and maintenance manual, supplied with the

15、machine. All operations performed on the generator should be undertaken by qualified personnel with specialist training in the commissioning, servicing and maintenance of electrical and mechanical machinery. This maintenance manual should be retained for the whole of the machine s life and be handed

16、 over with the contractual file.The various operations described in this manual are accompanied by recommendations or symbols to alert the user to potential risks of accidents. It is vital that you understand and take notice of the different warning symbols.1.2 - InspectionOn receipt of your alterna

17、tor, check that it has not sufferedany damage in transit. If there are obvious signs of knocks,contact the transporter (you may able to claim on theirinsurance) and after a visual check, turn the machine by handto detect any malfunction. 1.3 - IdentificationThe alternator is identified by means of a

18、 nameplate fixed on the frame.Make sure that the nameplate on the machine conforms to your order.The machine name is defined according to various criteria (see below).Example of description for : LSA 42.2 S4 J6/4 -?

20、ior to commissioning, machines should be stored : - Away from humidity : in conditions of relative humidity of more than 90%, the machine insulation can drop very rapidly, to just above zero at around 100%; monitor the state of the anti-rust protection on unpainted parts.For storage over an extended

21、 period, the machine can be placed in a sealed enclosure (heatshrunk plastic for example) with dehydrating sachets inside, away from significant and frequent variations in temperature to avoid the risk of condensation during storage.- If the area is affected by vibration, try to reduce the effect of

22、these vibrations by placing the generator on a dampersupport (rubber disc or similar) and turn the rotor a fraction ofa turn once a fortnight to avoid marking the bearing rings.ALTERNATEURS ALTERNATORSValeurs excit / Excit. values en charge / full load vide / at no loadMadebyLeroySomer-1024930/bTens

31、ng rings are for handling thealternator alone. They must not be used to lift the genset.Choose a lifting system which respects the positionning of therings.3.1.2 - Coupling3.1.2.1 - single bearing alternatorBefore coupling to the prime mover, check that both arecompatible by:- Undertaking a torsiona

32、l analysis of the transmission.-Checking the dimensions of the flywheel and its housing, theflange, coupling discs and offset.When coupling the alternator to the prime mover, theholes of the coupling discs should be aligned with theflywheel holes by cranking the engine.Do not use the alternator fan

33、to turn the rotor.Tighten the coupling discs screws to the recommendedtorque (see section 4.6.2.) and check that there is lateral playon the crankshaft.3.1.2.2 - two-bearing alternator- Semi-flexible couplingCareful alignement of the machines by measuring theconcentricity and parallelism of the two

34、parts of the couplingis recommended, the difference between the teadings shouldnot exceed the specified values (say 0,1 mm).This alternator has been balanced with a 1/2 key.3.1.3 - LocationEnsure that the ambient temperature in the room where thealternator is placed cannot exceed 40 C for standard p

35、owerratings (for temperatures above 40 C, apply a deratingcoefficient). Fresh air, free from damp and dust, must be ableto circulate freely around the air input louvres on the oppositeside from the coupling. It is essential to prevent not only therecycling of hot air from the machine or engine, but

36、alsoexhaust fumes. 3.2 - Inspection prior to first use3.2.1 - Electrical checksUnder no circumstances should an alternator, new orotherwise, be operated if the isolation is less than 1megohm for the stator and 100,000 ohms for the otherwindings.There are two possible methods for restoring the abovem

37、inimum values.a) Dry out the machine for 24 hours in a drying oven at atemperature of approximately 110 C.b) Blow hot air into the air input, having made sure that themachine is rotating with the exciter field disconnected.c) Run in short-circuit mode (disconnect the AVR)- Short-circuit the output p

38、hases using connections capable ofsupporting the rated current (try not to exceed 6 A/mm2).- Insert a clamp ammeter to monitor the current passingthrough the short-circuit connections.- Connect a 48 Volt battery in series with a rheostat ofapproximately 10 ohms (50 Watts), to the exciter fieldtermin

39、als, respecting the polarity.- Open fully all the alternator orifices.- Run the alternator at rated speed . Adjust the exciter fieldcurrent using the rheostat to obtain the rated output current inthe short-circuit connections.Note: Prolonged standstill: In order to avoid these problems,we recommend

40、the use of space heaters, as well as turningover the machine from time to time. Space heaters are onlyreally effective if they are working continuously while themachine is stopped.WARNINGWARNING名师资料总结 - - -精品资料欢迎下载 - - - - - - - - - - - - - - - - - - 名师精心整理 - - - - - - - 第 6 页，共 20 页 - - - - - - - -
