适用范围：Replacement:This part of IEC 61558 deals with the safety of small reactors for general applications.NOTE 1 Safety includes electrical, thermal and mechanical aspects.Unless otherwise specified, from here onward, the term transformer or reactor covers smallreactors.This part is applicable to stationary or portable, single-phase or polyphase, air-cooled (naturalor forced) general purpose reactors including alternating current, premagnetised and currentcompensated independent or associated reactors.The rated supply voltage does not exceed 1 000 V a.c. or 1 500V ripple-free d.c., the ratedsupply frequency and the internal operational frequencies do not exceed 1 MHz.The rated power does not exceed:– 25 kVAR a.c. (25 kW d.c.) for single-phase reactors,– 50 kVAR a.c. (50 kW d.c.) for poly-phase reactors.This part is applicable to reactors without limitations of the rated power subject to anagreement between the purchaser and the manufacturer.This part is applicable to dry-type reactors. The windings may be encapsulated or nonencapsulated.This part does not apply to:– reactors covered by IEC 60289;– ballast for tubular fluorescent covered by IEC 61347-2-8;– ballast for discharge lamps (excluding tubular fluorescent lamps) covered byIEC 61347-2-9.NOTE 2 For reactors filled with liquid dielectric or pulverised material such as sand, additional requirements areunder consideration.NOTE 3 Attention is drawn to the following:- for reactors intended to be used in vehicles, on board ships, and aircraft, additional requirements (from otherapplicable standards, national rules, etc.) may be necessary;- measures to protect the enclosure and the components inside the enclosure against external influences suchas fungus, vermin, termites, solar-radiation, and icing should also be considered;- the different conditions for transportation, storage, and operation of the reactor should also be considered;- additional requirements in accordance with other appropriate standards and national rules may be applicable toreactors intended for use in special environments, such as tropical environment.NOTE 4 Normally, reactors are intended to be associated with equipment for functional requirements of theequipment or requirements by the installation rules or by other appliance specifications.NOTE 5 Reactors incorporating electronic circuits and components are also covered by this standard.NOTE 6 The protection against electric shock may be provided (or completed) by other parts or features of theequipment, such as the body.NOTE 7 Reactors for particular applications will in the future be covered by complementary normative annexes.NOTE 8 Future technological development of reactors may necessitate a need to increase the upper limit of thefrequencies, until then this part may be used as a guidance document.
