General

YEIDA Bayonet Fuse Holders are used to protect transformers, switchgear, and distribution systems. They are designed for use in oil filled (or approved equivalents) single phase and three phase padmount transformers, switchgear, and submersible transformers. The assemblies combine the ease of hotstick operation with the safety of deadfront construction.

When the inner fuse cartridge holder assembly is removed from a Chardon Bayonet Fuse Holder installed on a padmounted transformer (or other apparatus), the transformer is electrically disconnected. This also allows for convenient fuse element and cartridge inspection and replacement. When using appropriate safety procedures, the Chardon Bayonet Fuse Holder can be loadbreak operated for disconnecting the transformer from the energized line, making changes to dual voltage or tap charger switches, or working on the transformers secondary connections.

Two options are available on the sidewall mounted Bayonet Fuse Holder.

1. A flapper valve is available inside the upper portion of the outer tube (see Figure 2). This flapper valve closes when the inner fuse cartridge assembly is removed. This results in minimal oil leakage from the transformer tank during fuse link replacements, especially when the pressure relief valve fails to remove all built up pressure inside the transformer tank. This reduces potential risk of environmental damage due to oil escaping from the transformer. It also reduces potential oil contamination to the rubber cable accessories mounted on the transformer. The flapper valve also reduces potential spillage due to pad tilting, or during installation and/or replacement of the transformer, when tilting of the transformer is likely to occur. The standard Chardon Bayonet Fuse Holder includes copper contacts for connection to the transformer. Optional silver plated contacts are available (and recommended) with high ampere bayonet fuse links. Silver pated contacts, along with high ampere fue links, allow the fusing or lager kVA transformers.

2.  Bayonet Fuse Holders are designed to be used with Current Sensing, Dual Sensing, and Dual Element fuse links. The Chardon Bayonet Fuse Holder must be used in series with a current limiting fuse, or isolation link, to prevent the possibility of a high current fault – even after replacement of a fuse link. Partial range current limiting fuses use the low current clearing capabilities of the Chardon Bayonet Fuse Holder while protecting the transformer or apparatus from high current internal faults that could cause failure to the specific piece of equipment, as well as other system damage
