1 - Winding 311 and 312 Technical Da Sheet

2 SPECIFICATIONS & OPTIONS WINDIN 311 and 312 SHAFT & KEYS Stamfd industrial ge meet the requiremts of BS EN 634 and the relevant secn of oth intnional standards such as BS5, VDE 53, NEMA M1-32, IEC34, CSA C22.2-1, Oth standards and ctificio can be coided on request. All g rots are dynamically balanced to bett than BS6861:Part 1 rade 2.5 f minimum vibrion in opion. Two bearing ge are balanced with a half key. INSULATION/IMPRENATION STANDARDS The iulion system is class 'H'. All wound componts are impregned with mials and processes designed specifically to provide the high build required f stic windings and the high mechanical strgth required f roting componts. VOLTAE REULATORS MX321 AVR - STANDARD This sophisticed Automic Voltage Regul (AVR) is incped into the Stamfd Pmant Magnet (PM) system and is fitted as standard to ge of this type. The PM provides pow via the AVR to the main excit, giving a source of cotant excin pow indepdt of g output. The main excit output is th fed to the main rot, through a full wave bridge, protected by a surge suppress. The AVR has in-built protecn agait sustained ov-excin, caused by intnal extnal faults. This de-excites the machine aft a minimum of 5 seconds. Ov voltage protecn is built-in and sht circuit currt level adjustmts is an opnal facility. QUALITY SURANCE e are manufactured using producn procedures having a quality assurance level to BS EN ISO 91. The sted voltage regulion may not be maintained in the presce of ctain radio tramitted signals. Any change in pfmance will fall within the limits of Critia 'B' of EN 6-6-2:21. At no time will the steady-ste voltage regulion exceed 2%. WINDINS & ELECTRICAL PERFORMANCE DE RATES All g sts are wound to 2/3 pitch. This elimines tripl (3rd, 9th, 15th ) harmonics on the voltage wavefm and is found to be the optimum design f trouble-free supply of non-linear loads. The 2/3 pitch design avoids excessive neutral currts sometimes se with high winding pitches, wh in parallel with the mai. A fully connected damp winding reduces oscillio during paralleling. This winding, with the 2/3 pitch and carefully selected pole and tooth desig, eures vy low wavefm distn. All vaes tabuled on page 8 are subject to the following reduc 5% wh air inlet filts are fitted. 1% wh IP44 Filts are fitted. 3% f evy 5 metres by which the oping altitude exceeds metres above mean sea level. 3% f evy 5 C by which the opional ambit tempure exceeds 4 C. Note: Requiremt f oping in an ambit exceeding 6 C must be refred to the facty. TERMINALS & TERMINAL BOX Standard ge feure a main st with eith 6 ds (Winding 312) 12 ds (Winding 311) brought out to the tminals, which are mounted on the frame the non-drive d of the g. A sheet steel tminal box contai the AVR and provides ample space f the customs' wiring and gland arrangemts. It has removable panels f easy access.
