A module connects a network having a power mains to a housing. The module includes a platform for holding electrical components. The platform includes a body made of a fiber-composite material and reinforcing glass fibers, a busbar in the body, and a contact element associated with the busbar for making contact with the busbar. A hood is connected to the body. A functional unit is in the hood. The functional unit includes at least one capacitor per current phase of the power mains.
摘要:
A bridge circuit consisting of two or more resistance strain gauges is formed on a synthetic layer on which a resistance layer and a metal layer provided for the terminal elements are applied. The corresponding patterns are etched into the metal and into the resistance layer. Balance surfaces consisting of materials with a temperature coefficient different from that of the resistance layer are connected in series to the resistance strain gauges. By changing the resistance of the balance surfaces, the circuit is balanced in terms of symmetry, in terms of the temperature coefficient of the resistance layer, and in terms of the temperature coefficient of the modulus of elasticity of the test object.
摘要:
A process for producing electric stacked capacitors including forming a folded track of capacitor materials which is only a fraction of the thickness of the final capacitor, cutting the folded track into segments equalling the length of the capacitor, stacking the segments on a conveyor belt, hardening the stack, providing external contacts and encasing the capacitor. The process may include placing the folded track on their folded edges and applying pressure between a pair of clamps which have recesses to allow the subsequent forming of the contact regions by a metal spraying process.

A method and apparatus is disclosed for the production of an electric stack or layer capacitor of metallized synthetic material films. The capacitor is produced by bending or folding a film by means of a set of folding wheels which are spaced double the folding width at the film inflow and are spaced as close as possible to one another at the film outflow. The invention is advantageously utilized for the production of layer capacitors.

摘要:
A housing can be used for high-power components, especially high-power capacitors. A housing has a carrier platform made from a suitable electrically insulating material and a preferably metallic cover, wherein the thermal expansion coefficients of the platform and of the cover are matched to each other. This matching is achieved according to the invention by adjusting the glass-fiber coefficient of a fiber-composite material.
