适用范围：1.1 Reactors covered by this standard ( Part 2 ) are intended for shunt connection in a system to compensate for capacitive current.NOTE — The absorbed reactive power at rated voltage can be constant or may be varied by use of additional devices:a) Variation can be achieved, for example, by phase-controlled thyristors ( static var source ) or by dc magnetization of the iron core; andb) Variation can be achieved by winding tappings, by means of off-load or on-load tap changer ( variable reactance ).1.2 DesignWith regard to design and installation, the reactor is identified as:a) Single-phase or three-phase,b) Dry-type or oil-immersed,c) With air core or with gapped iron core,d) With or without magnetic shield,e) For indoor or outdoor installation,f) For fixed or variable reactance, andg) Having additional loading winding.1.3 Magnetic CharacteristicKnowledge of the entire magnetic characteristic as shown in Fig. la, lb and lc may be necessary for:a) to set a normal operation range,b) study of over voltage conditions, andc) simulation in system studies.NOTE — Information on magnetic characteristics should be supplied on request.With regard to its entire magnetic characteristic, the reactor is identified as:a) linear, Fig. la;b) non-linear, Fig. lb;The reactors with non-linear magnetic characteristic have their normal operation range in the linear part of the magnetic characteristic; andc) saturated, Fig. lc.
