Over Current Protection Power Transformer Fuse 50Hz Electric Operation 108c04

Bay O Net tap changer switch for oil transformer
    This kind of switch applies to single-phase, three phase , combination oil-immersed transformer electrical power with frequency of 50HZ,,60HZ,rated voltage of 10KV,35KV,rated current of 30A ~500A; the voltage-regulating mode are: central part, terminal point neutral point, which can be directly fixed on the tank cover of the transformer, exchange under the off-circuit condition.

Bay- O-Net Assembly is the brief element of oil-transformer, to protect the equipment when over-current. When install the fuse wire in it, the Bay-O-Net will provide the safe, highly efficient protection, according to the current, oil-femperature.
The Bay-O-Net Assembly is suitable for current sensing fuse wire, dual sensing fuse wire, dual element fuse wire, and ELSP current-limiting backup fuse, etc.
It is suitable for high-voltage power system with alternating current of 50Hz,standard voltage of 15. 5kV, current rating of 140A. It must be combining with MagnX Interrupter of ELSP Current-Limiting Backup Fuse to protect transformer from overload and short circuit.
