Abstract:
A system for generating a path to be followed by a robot used to perform a process on a workpiece has a computing device that has program code for operating the robot and obtaining information related to the workpiece and a vision system that scans the workpiece to obtain images thereof that are provided to the computing device. The computing device processes the images to obtain geometric information about the workpiece that the computing device uses in combination with process related reference parameters stored in the computing device to generate program code for a path to be followed by the robot to perform the process on the workpiece. The computing device also includes code configured to verify for quality the generated program code for the path to be followed by the robot to perform the process on the workpiece.
Abstract:
A gas-insulated high-voltage switch for the interruption of large currents includes a housing, a contact arrangement which is arranged in the housing and has two switching pieces which can be moved relative to one another along an axis. Each switching piece has a rated current contact and an arcing contact. The switch includes a drive which acts on a first of the two switching pieces. The switch includes a device configured to detect and indicate the contact wear of the two arcing contacts caused by the action of the arc. The device has an indicator arranged outside the housing. In the switch, the remaining life which is determined by the contact wear of the arcing contacts is detected and indicated by a simple mechanical mechanism. The device has a transmission mechanism which is fed through the housing in a gas-tight manner and a drive member coupled to the operating element.
Abstract:
Mounting structure is provided for mounting a tank to support structure. The tank has a flange extending from a body thereof. The mounting structure includes at least a pair of first bores extending into the flange in a first direction. At least a pair of second bores. Each second bore extends into the flange in a direction generally transverse with respect to an associated first bore so that each second bore communicates with the associated first bore. A pin is disposed in each of the second bores. Each pin has a threaded pin bore that aligns axially with the associated first bore. A bolt is disposed through a bolt hole in the support structure, into an associated first bore and in threaded engagement with the threaded pin bore of an associated pin so as to secure the tank to the support structure.
Abstract:
A tank for a dead tank circuit breaker includes a body having an interior volume defined by an interior surface. A particle trap structure includes a pair of recessed surfaces in a bottom portion of the interior surface. Each recessed surface is disposed in spaced relation with respect to the interior surface so as to define a channel. A raised surface is spaced from the recessed surfaces and separates the recessed surfaces. The channels are constructed and arranged to trap foreign particles in the interior volume, with the raised surface being constructed and arranged to raise an electric field in the interior volume to be above the channels so as to eliminate electrical activity that would affect the particles in the channels.

A rotor as disclosed for an electric machine which includes a rotor core having a plurality of rotor sheets stacked in an axial direction, each of the plurality of rotor sheets having a plurality of flux paths made of a material of high permeance, a plurality of flux barriers made of a material of low permeance, a plurality of bridges made of a material of high permeance, each of the plurality of bridges extending across a corresponding flux barrier, and at least one axial magnet located axially adjacent a corresponding bridge and configured to saturate the corresponding bridge, each axial magnet being axially pressed between two elements at least one of which is a bridge corresponding to the axial magnet.
Abstract:
A contact-finger-element includes a first contact-portion and a second-contact-portion which are suitable for engaging with a first conducting terminal and with a second conducting-terminal respectively; the first-contact-portion and the second-contact-portion have respective cross-sections including concave “V”-shaped profiles, each concave “V”-shaped profile having two straight portions mutually tilted by a respective included angle which is adapted so as to enable the first contact-portion and the second-contact-portion to tangentially contact with a curved surface of the first conducting terminal and of the second conducting terminal respectively at intermediate zones of the respective straight portions. There is also disclosed a tulip-contact assembly comprising a plurality of such contact-finger-elements.
Abstract:
A contact arrangement has a longitudinal axis and includes a first contact group with a first contact and a second contact and a second contact group with a third contact and a fourth contact. The first contact interacts electrically and mechanically with the third contact, and/or the second contact interacts electrically and mechanically with the fourth contact, for closing and opening the contact arrangement. At least one mechanical coupling is provided for transmitting an actuation force to the second contact group and thereby moving the second contact group. The at least one mechanical coupling is adapted to move the third and the fourth contact in such a way that their speeds differ along at least a portion of a travel path of the third contact or along at least a portion of a travel path of the fourth contact.
Abstract:
A method for single-phase islanding detection in a three-phase electricity network, can include supplying power into a three-phase electricity network (EN) by a power supply assembly (PSA), the electricity network (EN) having a network voltage, and providing a stimulus signal into a positive sequence electric quantity of the electricity network, the positive sequence electric quantity being current, power or a derived quantity thereof. A magnitude and/or a rate of change of an indicative element of a negative sequence component of the network voltage is monitored, a frequency domain of the indicative element including a frequency corresponding to the stimulus signal. A single phase islanding condition is detected in the electricity network (EN) if the magnitude and/or rate of change of the indicative element exceeds a predetermined limit value.
Abstract:
A subsea pressure compensation arrangement is disclosed as having a vessel filled with insulating fluid, and a pressure compensator for compensating pressure variations of the insulating fluid. The arrangement can include a fluid connection pipe for fluid communication between the vessel and the pressure compensator, wherein the fluid connection pipe is connected to a bottom wall of the pressure compensator. A pipe opening arranged at an end of the fluid connection pipe extends above a level of the bottom wall of the pressure compensator.
