摘要:
The invention generally relates to a composite, comprising a layer sequence; wherein the layer sequence a) comprises as layers i) a first layer, comprising A. a first ceramic, and B. a first layer surface,
ii) a second layer, A. comprising a second ceramic, B. superimposing the first layer surface;
b) comprises i) a hole, connecting through each layer of the layer sequence; ii) a cermet;
wherein the cermet comprises a first part and a second part; wherein the first part is comprised by the hole; wherein the second part is comprised between the first layer and the second layer; wherein the cermet is in one piece. The invention further relates to a process for manufacturing a composite, comprising a cermet feedthrough; to a composite obtainable by said process; to a device comprising a composite according to the invention; and to a use of a plurality of ceramic green sheets and a composition to produce a composite according to the invention.

A high density capacitor comprises a housing having a cavity, and a plurality of capacitors forming at least one capacitor bank disposed in the housing cavity. A native cooling fluid is disposed in the cavity, and a heat exchanger is coupled to the housing. A pump is configured to circulate the native cooling fluid from the cavity, through the heat exchanger, through the spacings along an outer surface of each of the capacitors to cool the capacitors using forced convection. The heat exchanger is configured to communicate a secondary fluid through the heat exchanger and draw heat from the native cooling fluid flowing through the heat exchanger. The heat exchanger may have a plenum having a plurality of openings configured to dispense the native cooling fluid from the heat exchanger proximate the at least one capacitor bank.

A capacitor assembly and a method of assembling a capacitor assembly are provided. The capacitor assembly has at least two capacitor stacks, which have a layer structure including a top layer and a bottom layer. A support assembly supports the capacitor stacks. The capacitor stacks are stacked on top of each other in the support assembly. The support assembly has a compression member which compresses the at least two capacitor stacks in a direction substantially perpendicular to the layer structure. A pressure distribution arrangement adjusts the distribution of the pressure applied to the capacitor stacks by the compression member. Further, a subsea device in particular a subsea variable speed drive is disclosed.

An epoxy resin composition is disclosed for joining dissimilar materials. The identified epoxy resin compositions can be used to seal metallic and non-metallic components of a capacitor. Specifically the epoxy resin composition can be applied to joints between a non-metallic capacitor bushing and a metallic tank cover and metallic terminal cap. Once the epoxy resin composition is cured, it can provide a seal that can withstand the stresses and environmental conditions to which a capacitor is subjected.
