插入式限流熔丝 38kV Bay-O-Net fuse link

Eaton（Cooper）插入式限流熔丝 38kV Current sensing Bay-O-Net fuse link （4000380 Series）

Eaton protects distribution apparatus from damaging currents and distribution systems from failed apparatus with its Cooper Power™ series 38 kV Bay-O-Net fuse link when used in Eaton's Cooper Power series 38 kV silver-plated Bay-O-Net assemblies. (See Catalog CA132015EN 23 kV and 38 kV Sidewall-Mounted and 23 kV Cover-Mounted Bay-O-Net Fuse Assembly for information about the fuse assembly).

38 kV Bay-O-Net fuses were designed to allow the fusing of solar, wind and other 24 – 38 kV rated pad-mounted transformer applications.

Its ideal use is in a two-fuse protection scheme with a current-limiting backup fuse. In this arrangement, secondary faults and overload currents are cleared by the Bay-O-Net fuse, and high level faults are cleared by the current-limiting fuse. The two fuses are connected in series and are coordinated so that the current- limiting fuse operates only upon internal transformer failure (see Catalog CA132013EN ELSP Current-Limiting Backup Fuse to order an Eaton ELSP currentlimiting back-up fuse).

The 38 kV Bay-O-Net fuse is an integrated fuse link and cartridge design specially engineered to simplify re-fusing and prevent mis-installation. The Bay-O-Net fuse design allows the integral (link) cartridge to be easily field replaceable in a 38 kV Bay-O-Net assembly.

38 kV links should only be used in Eaton's Cooper Power series 38 kV silver-plated Flapper™ valve Bay-O-Net fuse assemblies in order to ensure the intended operating characteristics.

All 38 kV fuse links must only be used in series with a 38 kV rated ELSP current-limiting backup fuse or equivalent. 38 kV fuse links cannot be used with an isolation link.

No special tools are required. A hotstick is used to remove the Bay-O-Net fuse cartridge holder from non-pressurized apparatus. The entire fuse cartridge is then replaced. No field installation of the fuse link into the cartridge is required. The fuse holder is then reinstalled into the apparatus using a hotstick. Refer to Service Information MN132002EN Bay-O-Net Fuse Re-Fusing Installation Instructions for refusing instruction.
