Description
The MJB/MJH series is the main line of synchronous generators for generator sets driven by internal-combustion engines and turbines. The letter B designates low-voltage MJB machines and the letter H medium-voltage MJH generators. The generators have open self-ventilation IC01 and are designed for installation in machine halls and containers. Parameters: power up to 15,000 kVA (the series announcement on the website cites up to 12,500 kVA), voltage up to 15,000 V, frequency 50 or 60 Hz, 4–12 poles, frame sizes 315–1250, degree of protection IP23 (up to IP44 on request, with filters on the air inlet and outlet), ambient temperature −15…+60 °C. Standards IEC 60034-1, BS 4999-5000, NEMA MG 1.32. Voltage regulators: for low-voltage machines E-Vo up to frame size 630 and MGC II above; for medium voltage up to 6900 V MGC I up to frame size 560 and MGC II above; above 6900 V the digital D-Vo Light. Main options per the catalogue: flanged shaft for direct connection to the engine flywheel (single-bearing design), reinforced construction for high linear vibration, neutral terminals in a separate box, raised feet for mounting on the set frame (B20 – IM1101), current transformer in the neutral for differential protection and measurement, insulated bearing and shaft earthing brush, rotor earth-fault protection (64R), preparation for vibration sensors, and a permanent-magnet pilot exciter (PMG) for excitation boost. Rolling bearings or, on request, sliding bearings; UL/CSA certification on request. Application areas according to the manufacturer: power generation, cogeneration, standby and emergency power supply, uninterruptible power systems and data centres. The manufacturer is one of the largest OEM suppliers of generators for Caterpillar and partners with Bergen Engines on modular power stations. The item is an analog of synchronous generators of the SG, GSD and SGDM types for diesel and gas-engine power stations of 0.4–10.5 kV.
