New & Renovation
BH2M can supply new alternators or replace all or part of existing machines, adapting the electrical and mechanical design to the required operating and efficiency conditions.
BH2M can supply new alternators or replace all or part of existing machines, adapting the electrical and mechanical design to the required operating and efficiency conditions.
BH2M covers the entire spectrum of alternator-related activities, from the electrical and mechanical design phase to the supply and installation of components (Magnetic circuit, poles, windingsetc.).
Our studies are carried out according to operating conditions (voltage, power, inertia, Cos Phi, etc.) and guarantee high levels of efficiency.
Nos équipes disposent des outils numériques et de réingénierie permettant de proposer un alternateur sur mesure et en totale intégration avec son environnement (Turbine, Génie Civil, BoP, Contrôle Commande). We can also add optional systems to further enhance the operability and performance of our alternators:dust extraction systems (braking and static excitation), oil mist extraction, injection systems for bearing preservationor monitoring systems (vibration, partial discharge, air gap, etc.).
Systems & Components
La compétence de ses experts permet à BH2M, sur la base de l'analyse des machines existantes, d'offrir à ses clients de nombreuses fournitures en lien avec l’exploitation des alternateurs hydroélectriques. BONJOUR
BH2M can supply wear parts, replacement electrical components, auxiliary systems and instrumentation. In all cases, these supplies are combined with a study of the existing system and the customer's expectations, to ensure the proper integration of the systems and/or components supplied.
Spare parts: bearing pads (bearing and pivot), brake cylinders, coolants, manifolds, etc...
Electrical components : stator coils, stator bars (roebel)pole coils, poles, interpolar connections, damper connections, etc...
Auxiliary systems: stator cooling, bearing coolingbraking system with cylinders or clamps, oil injection system, oil mist extraction, dust extraction (braking and static excitation), dehumidification systems (heating resistors and dehumidifiers), lighting, etc...
Instrumentation: oil levels, temperature probes, flow meters, flow measurement, etc...
Monitoring : vibrations, partial discharges, air gap, etc...
Tools assembly and handling (stator winding assembly, stator and rotor handling, disassembly of pivot shoes, etc.)
Services
With its experts, BH2M can provide its customers with technical support throughout the value chain of the hydroelectric alternator product.
This assistance ranges from validation of technical documentation to commissioning and performance testing, as well as acceptance of alternator components. In all these missions, BH2M plays the role of advisor in order to provide a high quality of service and the added value expected by its customers.
A few examples of our services:
Electrical measurement and diagnostics, magnetization of magnetic circuits, shaft alignment, rotor balancing
Validation of technical documentation (general drawings, manufacturing drawings, calculation notes, assembly procedures, commissioning procedures)
Receipt of alternator components (poles, stator bars (roebel), stator coils, rotor assembly, stator assembly)
Assistance and supervision of alternator assembly
Advanced finite element analysis
