摘要： A universal insulating cap for both standard-style and new-style arrester brackets is disclosed. The insulating cap has a slotted portion sized to receive a rib of an arrester bracket so that the cap may be affixed to the rib by sliding the cap over the rib. A cover portion of the cap extends forward from a slotted portion and is sized to at least partially cover a bolt or fastener that connects the arrester bracket to a mounting bracket affixed to a transformer tank. Projecting members extend from the inner walls of the cover portion and contact the sides of the standard-style arrester bracket to aid in holding the cap in place. The space between the projecting members is sized to receive a rib of the new-style arrester bracket to aid in holding the cap in place.

摘要： Described herein are DC-DC converters with a ratio of the power output to volume of at least 2 kW per liter or even at least 4 kW per liter. Such DC-DC converters can operate at power levels of at least 150 kW or even at least 200 kW. A DC-DC converter comprises an enclosure and a front plate sealed against the enclosure using a set of fasteners. The DC-DC converter also comprises a converter unit comprising a switching sub-module, a diode sub-module, and an inductor as well as an additional converter unit comprising an additional switching sub-module, an additional diode sub-module, and an additional inductor. The switching sub-module and the additional switching sub-module or, more generally, the converter unit and the additional converter unit are configured to operate out of phase. The inductors are immersed cooled, the switching sub-modules are conductively cooled, while the diode sub-modules are convectively cooled.
