121 METHOD AND DEVICE FOR THE SECURE OPERATION OF A SWITCHING DEVICE PCT/EP2005057072 2005-12-22 WO2006069955A2 2006-07-06 HARTINGER PETER; MITLMEIER NORBERT; POHL FRITZ; ZIMMERMANN NORBERT
The invention relates to a method and to a device for the secure operation of a switching device comprising at least two main contacts which can be switched on or off, and which, respectively, comprise contact pieces and a displaceable contact bridge, and at least one control magnet which comprises a displaceable anchor. The anchor acts upon the contact bridge when it is switched on or off such that the corresponding main contact is opened or closed. The method comprises the following steps: a) a circuit monitoring agent is transferred in a first state if the main contacts are closed when switched on, b) the circuit monitoring means remain in said first state after switching off if at least one of the main contacts is welded.

123 ELECTRIC SWITCH PCT/DE0204039 2002-10-30 WO03041100A2 2003-05-15 WOLBER RALPH; KIZELE RAINER; MUELLER HEINRICH; MEJERL THOMAS
The invention relates to an electric switch (1), especially for a high load, such as a mains switch. Said switch (1) comprises a contact system (7) that consists of a movable switching contact (8) and at least one stationary contact (9). A movable actuation member (5) interacts, when displaced, with the switching contact (9), thereby switching the contact system (7). Optionally, the switch (1) can also be provided with a movable locking device that interacts with the actuation member (5) while interlocking with it. The actuation member (5) is functionally linked with a lever (10) in such a manner that the lever (10) undergoes a pivoting movement when the actuation member (5) is actuated. Said pivoting movement of the lever (10) displaces, especially while increasing the path covered by the actuation member (5), the switching contact (9) for the purpose of switching and/or the locking device for the purpose of locking.
124 DEVICE FOR FORCIBLE SEPARATION OF MAIN SUPPLY LINES IN SWITCHING DEVICES PCT/DE9602148 1996-11-12 WO9718571A2 1997-05-22 SCHOLZ GERHARD
All switching devices which have the purpose of protecting people or objects from the harmful effects of electric current include at least triggering elements which trigger the appropriate switching mechanisms whenever predetermined threshold values are exceeded. This opens the main current contacts in the switching device, thus usually stopping current flow. However, such switching devices occasionally fail in an emergency situation because, for example, the trigger elements stick, the switching mechanisms jam, the contacts become welded together, or because of other faults. For such eventualities, a device is proposed for forcibly interrupting the appropriate mains or main current lines with a work storage unit. The latter produces a force along a pathway and is kept in an inactive state by a locking mechanism. The locking mechanism can easily be released by a trigger controlled by the switching device and the work storage unit can thus be freed to switch to its active state. A separator device driven by the work storage unit then forcibly separates the current lines. The device is especially suitable for incorporation in or combination with protective switches such as fault current protective switches, automatic cut-outs, bus protection switches, motor protection switches, power protection switches and the like.

Current measurement means inputs single-phase current that is output from current measurement equipment and calculates (current measurement step) the current flowing in the ganged three-phase operation breaker when the ganged three-phase operation breaker interrupts the inductive load. Based on the measurement results of this current measurement equipment, phase detection means detects (phase detection step) a first interrupting phase selected from the three phases of the ganged three-phase operation breaker and the current interrupted point of this first interrupting phase. An open command output means sets a contacts-opening range between the time point obtained by back-calculation of the minimum arcing time for which current interruption is feasible without generating reignition and the current zero-point in the phase that is advanced by 120° phase from the first interrupting phase, starting from the current interrupted point as a base point, and outputs an open command to the three-phase breaker in this contacts-opening range (open command output step).

The invention relates to a system for balancing current paths that are connected in parallel, especially current paths of electrical switchgear. In order to improve the balance between the partial currents in the current paths, each current path (L11; L12; L13) is linked in pairs to the secondary winding (S22; S32; S12) of a current supply line (U22; U32; U12), said supply line being associated with a different current path (L12; L13; L11), via the secondary winding (S11; S21; S32) of a current supply line (U11; U21; U31) in such a manner that the secondary windings (S11, S22; S21, S32; S31, S12) which are connected in pairs in an anti-series manner form a closed circuit.
130 A CONFIGURABLE CIRCUIT BREAKER EP08719182.1 2008-02-15 EP2255423A1 2010-12-01 SINGH, Shailendra; DUKKAIAPPAN, Subbiahthever
A configurable circuit breaker, applicable for medium voltage range, with flexibility in configuration, based on the electrical and mechanical constraints. It has multiple poles, which can be fitted on a shaft at required positions, using the clamping, dowelling, bolting etc. An epoxy frame is provided for mounting the circuit breaker on the truck horizontally or vertically, by means of the mounting inserts and the clamping mechanism. The side sheets of the pole allow access to its internal. The flexible contacts and the vertical slots enable adjustability in the incoming and outgoing distances, as per the design constraints. A tulip contact can be connected to the conducting stub in the contactor, for mounting the incoming/outgoing conductor. Common actuator can be mounted anywhere on the shaft, via the movable contact or on any of the poles, which are robust enough. The circuit breaker is hence flexible in size and configuration.

Described ia a multi-pole low-voltage power switch (1) designed with several switching chambers (3) per pole and a common switching shaft (2) which acts for the pole units (9) formed by the switching chambers (3). The switching shaft (2) is made up of shaft sections (21, 22, 23) which correspond to the pole units (9). While the central shaft section (21) has central pins (24) and levers (25), the peripheral shaft sections (22, 23) are fitted with levers (30) and have central apertures (27) in which the pins (24) engage. Bolts (35) which pass through the levers (25, 30) are used to couple the shaft sections (21, 22, 23) together. The pole units (9) rest on a support (20) which is dimensioned to accommodate the maximum width of the pole units (9) and to allow for possible variations in their dimensions. Side walls (4) of the correct dimensions for a pull-out rack (8) enclose the supporting framework (5) of the power switch (1) on each side.
