The demand for electrical power is continually increasing and traditional methods of energy production, such as nuclear, Hydroelectric and coal-fired power stations have been supported by growth of renewable energy technology such as wind, solar and tidal power. As countries all around the world are striving to become more reliant upon efficient and environmentally friendly electrical energy the requirements to store the energy generated by renewable and more traditional methods within battery storage systems is rapidly becoming a necessity.
Modern storage
Modern battery storage systems are modular, easy to deploy close to power generation networks and can even be retrofitted into existing systems. The batteries contained within these power banks can contain Lead Acid, lithium-ion, AGM and NiCad and any installation will feature a Battery Management System (BMS) to ensure good battery health, ensuring the batteries cannot be overcharged or over-discharged. The BMS, together with high-quality Battery Storage Fuses are designed to provide the battery storage installation with protection from dangerous overcurrents and short circuits.
The expansion of this power storage network is having a demanding effect on electrical system architecture and as a consequence their overcurrent protection needs. Battery storage system protection requirements differ compared to typical grid-connected AC systems, here they are required to operate with DC systems which may have high fault currents and a number of lower overcurrent instances.
The forefront of design
Eaton has been at the forefront of this drive, continually innovating and making sure battery storage systems for schools, offices, shopping centres and large scale utility storage systems operate safely. With their extensive knowledge and experience behind them, Eaton has created a range of Bussmann Battery Storage Fuse Links that are have been specifically designed and tested to safely protect battery storage systems with high DC voltages and low fault currents.
The BSF-NH Range of Fuse Links
Eaton Bussmann’s BSF-NH series of Battery Storage Fuse Links have been specifically designed to isolate and protect battery array combiners and disconnects. The BSF-NH range is capable of interrupting low overcurrents that are associated with faulted battery storage systems. Available in bolted tag or bladed fuse link versions.
A range of associated fuse bases available in SD1 (250 A), SD2 (400 A) and SD3 (630 A) sizes and shroud kits, fuse extractors, microswitches, neutral links and phase barrier kits suitable for the BSF-NH range of Battery Storage Fuse Links are available to help complete your installation.
