The invention relates to electrical switchgear in which the switchgear parameters are adjusted by means of remote control and which additionally have apparatuses with which these parameter values can be read off directly from the switchgear. The invention also relates to a method for ensuring that currently set switchgear parameters and a parameter value display on the appliance itself correspond. Whereas the current setting value can be directly read off on the appliance by means of the arrow of the one slot (26) and the scale marking (30) when a switchgear parameter is adjusted by means of the adjustment knob (21) directly on the appliance, in the case of remote adjustment of this setting value in prior art appliances the set value may differ from the position of the adjustment knob (21) and therefore the position of the slot with the arrow (26) in relation the scale marking (30).

Furthermore according to the invention, if a switchgear apparatus parameter is set by means of an electromechanical device, a servomotor is provided on the setting device of the switchgear apparatus parameter on the apparatus itself. Said servomotor is activated during the fine setting of the corresponding parameter value and adjusts the setting device accordingly.

H01H 83/22 - Protective switches, e.g. circuit-breaking switches, or protective relays operated by abnormal electrical conditions otherwise than solely by excess current operated by excess current as well as by some other abnormal electrical condition the other condition being imbalance of two or more currents or voltages
The invention relates to a locking device for a switch cabinet for a multi-pole electric power circuit breaker arranged in a switch cabinet on an extension unit such that it can be moved between an operating position, a test position and an isolated position. When an auxiliary release (20, 30) is actuated from the outside of the switch cabinet door (14), the securing unit permits access to the switch cabinet even in barred positions comprising the operating position (C) and test position (T). The securing unit comprises a pivoting bolt (20) provided with a latch (21), and a locking lug (30) which interlocks with the latch (21) and produces the bar to access. The auxiliary release consists in that the locking catch (30) is fixed in a position that can be changed from the outside of the switch cabinet door (14) by using an auxiliary release tool. The locking catch (30) is held such that it can rotate like a rocker. The locking catch (30) assumes the door-release position when actuated with the auxiliary release tool. After being actuated with the auxiliary release tool, the locking catch (30) rotates from the door-securing position into the door-release position as a result of its own weight.
The invention relates to a switch (1) suitable for DC applications comprising two fixed conductive contacts (2) with first contact areas (21, 22), a movable conductive bridge (3) with two second contact areas (31, 32) for being connected to the two first contact areas (21, 22) in the on- status and for being disconnected from the two the first contact areas (21, 22) in the off- status and two arc-extinguishing units (41, 42) to extinguish electric arcs (51, 52) occurring between the first and second contact areas (21, 22, 31, 32) after disconnecting the second contact areas (31, 32) from the first contact areas (21, 22), wherein first conductive arc-guiding elements (61) extend from each first contact area (21, 22) into the corresponding arc-extinguishing unit (41, 42) and at least one second conductive arc-guiding element (62) extends into the arc-extinguishing units (41, 42) suitably shaped to guide the electric arcs (51, 52) from each of the second contact areas (31, 32) of the movable bridge (3) into the arc-extinguishing units (41, 42), wherein at least two permanent magnets (71, 72) are suitably arranged adjacent to the first and second contact areas (21, 22, 31, 32) to provide a magnetic field (B) suitable to support the guiding of the electric arc (51, 52) into the arc-extinguishing units (41, 42), wherein at least parts (621, 622) of the second arc-guiding element (62) are made of a magnetic permeable material, which are connected to the permanent magnets (71, 72) as a back iron for the permanent magnets (71, 72) to increase the strength of the magnetic field (B) between the permanent magnets (71, 72).

CURRENT MEASURING METHOD FOR SWITCHGEAR HAVING CURRENT PATHS CONNECTED IN PARALLEL
The invention relates to a current measuring method for switchgear having current paths (L21; L22) connected in parallel. The digital measured values (Ι1'; Ι21'; Ι21'; I3') derived from the path currents (i1; i21; i22; i3) are converted into corrective values (I1; I2; I3) to compensate (Kn; Kp) for the non-linear transmission characteristics (N) associated with the transformer-based current transformation. The respective total value and difference values are determined from the digital measured values (I21', I22') associated with the current paths (L21, L22) connected in parallel, wherein at least one respective difference value is included in forming the associated corrective values (12) and the associated corrective values (12) represent the total of the associated path currents (i21, i22).

ELECTRONIC OVERCURRENT RELEASE FOR CIRCUIT BREAKERS
The invention relates to an electronic overcurrent release for circuit breakers, comprising current transformers (11), the primary side of which is in each case linked to one of the phase currents (I1, I2, I3) to be switched and the primary side of which is in each case connected to a load resistor (13) by means of a rectifier assembly (12), to a microcontroller (15) having measurement inputs (41... 43), each of which is operatively connected to one of the load resistors (13), and a signal output (60), which is operatively connected to an electromagnetic actuator (16), a first setting means (S1) for selecting a suitable nominal current value, which is connected to at least one control input (50... 53) of the microcontroller (15), wherein the nominal current value can be selected in a range between a minimum nominal current value and a maximum nominal current value, and a second setting means (S2) for selecting a suitable degree of inertia, which is connected to at least one control input (50... 53) of the microcontroller (15). The invention is characterised in that the second setting means (S2) is additionally provided with a test position and that, when the test position is selected, a fixed test current value below the minimum nominal current value and a fixed test delay time are represented in the microcontroller (15), with a release signal (SA) being present at the release signal output (60) when at least one of the phase currents (I1, I2, I3) exceeds the amount of the value and time of the delay time.
