  Description:

Safety of transformers, reactors, power supply units and combinations thereof - Part 2-20: Particular requirements and tests for small reactors

  Purpose

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 small reactors. This part is applicable to stationary or portable, single-phase or polyphase, air-cooled (natural or forced) general purpose reactors including alternating current, premagnetised and current compensated independent or associated reactors. The rated supply voltage does not exceed 1 000 V a.c. or 1 500V ripple-free d.c., the rated supply 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 an agreement 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 by IEC 61347-2-9.
