2 General The ELBI switch disconnector is one of the classical switching devices. ELBI switch disconnectors are used in M.V. power networks for switching them on and off. They provide reliable and safety operation of the networks. ELBI switch disconnectors can be fitted in a vertical or horizontal position. They have a visible disconnecting distance after breaking. Types ELBI-HN is normal switch disconnector. ELBI-HS is switch disconnector with fuse base. Frame ELBI s robust construction has been designed for high electrical and mechanical stresses and based on a hot dipped galvanized steel frame. Insulators ELBI has high quality silicone rubber insulators.main advantages are low weight,outstanding dielectric strenght and extreme mechanical endurance.hovewer porcelain insulators is available. Main Contacts ll main contacts which terminals and blades are manufactured from pure copper and silver plated. rc Quenching Chamber ELBI are designed to be used in areas with severe environmental demand, which are met by oil-free arc quenching chamber, with arc quenching based on the gas-generation principle. This type of chamber is fully maintenance free. Internal mechanism of chamber is made from non-ferrous components insuring long term resistance to corrosion in all environments. That chamber capable of 50 successful 630 interruptions at rated 24kV. The mechanism of arc extinguisher makes it possible to perform 2500 successful closing and opening operations. Operation of arc quenching chamber Load break interrupter operates during a switch opening sequence. The switch blade pulls the operating arm open, which at a precise time drives the load breaker plunger toward the interrupter main body. This action causes the special load break contacts to quickly separate and plunge into the arc quenching material. The arc is then extinguished and vented out of the end of the interrupter. Once the blade pick-up arm clears the end of breaker operating arm, the interrupter automatically resets for the next load break operation. Packing The ELBI switch disconnectors are delivered in wooden case. Standarts ELBI switch disconnectors meet the requirements of IEC 265-1, IEC 694 and IEC 129 standards. Operating Conditions Max. Site ambient temperature : C Min. Site ambient temperature : - 10 C ltitude : 1000 m
