Techniques are described for workflow management, including automatically deriving characteristics of a user task node in a workflow based on an analysis of other workflow elements such as conditional sequence connectors. In some implementations, elements of a workflow presented in the modeler user interface of a workflow management platform are analyzed, and element(s) of the workflow are automatically and dynamically modified based on the analysis. For example, a workflow may include a first user task that is connected to subsequent node(s) in the workflow, such as other user task(s) downstream from the first user task. The first user task may be connected to each subsequent node by a conditional sequence connector. The condition information for each connector can be extracted from the workflow information and used to automatically modify the first user task to include decision branches for each element of condition information extracted from a respective connector.

An interrupter unit for a circuit breaker has two electrically conductive arcing contact pieces, which can be moved relative to one another along a switching path. An insulating nozzle has a nozzle channel through which the switching path runs. A heating volume is connected to the nozzle channel. A separating housing divides the heating volume into a cold gas region and a hot gas region. A cold gas duct runs through a nozzle channel end section of the nozzle channel and is connected to the cold gas region. A hot gas duct runs through the nozzle channel end section and is connected to the hot gas region.

Interrupter unit for a circuit breaker

A switchgear includes an interrupter unit. The interrupter unit is provided with first and second switching contact pieces that are movable relative to one another. A switching-gas duct that runs through the interrupter unit originates at an arc gap in which an electric arc can burn. The duct connects the arc gap to the surroundings of the interrupter unit. At least some sections of the switching-gas duct are delimited by mutually encompassing elements similar to an annular duct. One of the elements is a first member which is braced at the end similar to a pipe joint and which has a free end that projects in the direction of the arc gap.

Switchgear arrangement

A switching device arrangement has a first contact set and a second contact set. The first contact set includes a first electric arc contact element and a first nominal current contact element. The first nominal current contact element can be moved relative to the first electric arc contact element. A first transmission is introduced in a kinematic chain in order to generate a relative movement of the first nominal current contact element and the first electric arc contact element. The first transmission is operationally connected between a stationary counter bearing and the first electric arc contact piece.

Switching device arrangement

A switching arrangement has a first contact set and a second contact set which can be moved with respect to the first contact set, and an insulating nozzle arrangement. The insulating nozzle arrangement is supported on the first contact set which includes a first arcing contact piece. The first arcing contact piece can be moved with respect to the insulating nozzle arrangement.

Switching arrangement

An electric switching device contains a first contact piece and a second contact piece. The first contact piece can be driven by a first kinematic chain. The second contact piece can be driven by a second kinematic chain. The electric switching device contains a first switching point and a second switching point, which are electrically connected in series, the first contact piece being associated with the first switching point and the second contact piece with the second switching point.

Electric switching device

An electric switching device includes first and second switch contact pieces. The first switch contact piece has a guide portion. The first switch contact piece is connected to an actuating unit or drive device by a kinematic chain. The guide portion of the first switch contact piece is guided on a guide path. The guide portion and the guide path each have a contact or bearing surface and at least one of the contact or bearing surfaces is convexly curved.

Electrical switching device

A switching device has a first contact side with a first nominal current contact piece and a first electric arc contact piece, and a second contact side with a second electric arc contact piece and a second nominal current contact piece. In order to generate a relative movement between the first and second contact sides, the first electric arc contact piece and the first nominal current contact piece as well as the second electric arc contact piece and the second nominal current contact piece are driven. For switching, the first contact piece is moved by a movement profile and the first nominal current contact piece is moved by a movement profile that differs from the movement profile of the first electric arc contact piece. A movement profile of the second electric arc contact piece and the second nominal current contact piece deviate from each other.

Switching method and switching device

A switchgear has an interrupter unit that includes an arc gap. A first and a second switching contact piece are movable relative to one another. A switching-gas duct originates in the arc gap and connects the arc gap to the surroundings of the interrupter unit. A hollow vessel arrangement delimits at least some sections of the switching-gas duct and is connected to one of the contact pieces. The hollow vessel arrangement includes an external outlet opening for the switching-gas duct.

A circuit breaker unit has first and second arcing contact pieces. A breaker gap is formed between the two arcing contact pieces. A switching gas channel leads to the breaker gap and guides the switching gas to a switching gas outlet opening of the circuit breaker unit. The switching gas channel is formed with first and second pipe sections that overlap each other at least in sections and have discharge openings in their cover surfaces. Continuous discharge openings in the first and in the second pipe sections are axially offset in relation to each other.

Systems and methods for dynamic parallel looping in process runtime environment are described herein. A currently processed process-flow instance of a business process reaches a dynamic loop activity including a repetitive task to be executed with each loop cycle. A predefined expression is evaluated on top of the current data context of the process-flow instance to discover a number of loop cycles for execution within the dynamic loop activity. A number of parallel activities corresponding to the repetitive task recurrences are instantiated and executed in parallel. The results of the parallel activities are coordinated to confirm that the dynamic loop activity is completed.

A power circuit breaker unit has first and second arcing contact pieces. A contact gap is formed between the arcing contact pieces. A switch gas channel of the circuit breaker unit joins the contact gap to the surrounding area of the circuit breaker unit for removing a switch gas from the contact gap. Several barriers that increase a flow resistance are arranged successively, spaced from one another, in the switch gas channel. At least one of the barriers is arranged between a first pipe section, which is surrounded by a second pipe section, and the second pipe section.

Circuit breaker unit

An arc chamber for a circuit breaker has first and second mounting bodies. The mounting bodies are disposed at the ends of an electrically insulating insulation section of the arc chamber. The insulation section is formed of at least two shell-shaped partial sections. The partial sections are curved concavely relative to a longitudinal axis of the arc chamber. A gap is formed between the edges of the bodies of the partial sections.
