. GENERALLY Vcuum compct circuit breker series is third genertion of medium voltge vcuum circuit brekers mnufctured in - MEDIUM VOLTAGE APPARATUS, Inc. Vcuum compct circuit brekers hve been designed to meet requirements of domestic electric distribution networks, nd lso fit well in industril switchger. The design of these series complies with current world trends in medium voltge pprtus design nd development.. DESIGN Vcuum circuit brekers series re bsed upon ltest genertion of vcuum interrupters, distinguished by miniml dimensions nd msses. Product rnge of series covers rted voltges up to kv, rted breking/mking cpcities up to / ka nd rted currents up to. Circuit brekers re designed s three-pole units, with vcuum interrupters built into insulting cylinders. The complete line of circuit brekers is designed nd type tested in ccordnce with IEC Norms (Puliction -). According to construction digrm (Fig..), vcuum circuit brekers consist of the following ssemblies: A - Poles B - Operting mechnism C - Bse D - Trnsmission levers P, P - Terminls - Insulting cylinder of epoxy resin reinforced with glss-fiber - vcuum interrupter - fixed upper crrier - moving contct - flexible connection - lower connection housing - ddition of moving contct of vcuum interrupter - insulting lever - trnsmission lever Fig.. Constructionl digrm of circuit breker Spring chrging, energy storing operting mechnism type m- is used t circuit brekers series. Operting mechnism is mechniclly trip-free, with possibility of energy surplus restitution. These fetures mke the operting mechnism extremely relible nd endurble. Operting mechnism is equipped with motor drive, opening nd closing releses, nti-pumping device, uxiliry switch with NC nd NO contcts, nd -pin plug-in connector for connection of uxiliry circuits. Other specil fittings cn be delivered on customer s request (see Chpters, nd.)
