Abstract

The invention relates to a method for detecting electrical currents on or near electrical conductors with at least one reed switch as a magnetically responsive switch, which is arranged near the electrical conductor such that when there is a significant current flow through the conductor, the magnetic field created triggers the switch and initiates evaluation electronics connected to the switch. For the detection of surge current variables and differentiation between long-term pulsed currents and short-term pulsed currents, a plurality of reed switches is arranged at pre-determined, different, increasing distances from the electrical switch, the evaluation electronics determining the response and the switching times of the respective reed switches. The surge current variables are determined from the association of the determined values with the respective reed switch and the pulse shape from the switching time.

Abstract

The invention relates to a lightning and overvoltage protection device for data networks, telephony services, electroacoustic installations or bus systems having at least two grid-side input terminals and at least two output terminals, to which the load that is to be protected can be connected, furthermore having a gas-discharge surge arrester that connects the input terminals and an inductance located between the respective input and output terminal. According to the invention, the inductances are configured as current-compensated inductors having a core and a primary winding and a secondary winding, wherein the load current flows through the windings in different directions so that the respective magnetic fields cancel out. In the event of transient overvoltages, the arising surge current is bypassed by means of a switching device that then closes at one of the two windings, for example the secondary winding, in such a way that, owing to the winding through which current flows, for example the primary winding, the core reaches saturation and the coupling between the windings is released, with the result that no voltage is established across the load and the voltage applied to the winding through which current flows ignites the gas-discharge surge arrester.

Abstract

The invention relates to an arrangement for non-reversible detection and display of electrical overcurrents or current limit values by means of a pre-finished conductor. The conductor according to the invention has at least two conductor sections, spaced apart from each other and extending parallel to each other, which are designed for current to flow through in the same direction. At least one of the parallel conductor sections has a protrusion, a nose, or similar blocking element, which limits the path of movement of a mechanical display or switching element, such that the electromagnetic force acting on the parallel conductor sections during the flow of current transitions the blocking element into a release position in respect of the path of movement of the mechanical display or switching element. Such an arrangement can be used particularly advantageously as a prior damage indicator in surge arresters.

Abstract

The invention relates to a disconnection and switch-over device for overvoltage protection, particularly for DC systems, comprising at least one arresting element, and a thermal cut-off point incorporated into the electrical interconnect path of the arresting element, the thermal cut-off point comprising a movable mechanically prestressed conductor element that moves from a first position to a second position in the event of a cut-off, and when the second position is reached, an electrical switch-over to a safety device is generated, and the thermal cut-off point is formed by the movable conductor element and a stationary contact element, the movable conductor element being attached to the stationary contact element by a thermally releasable means.

Abstract

The invention relates to an electronic circuit-breaker for a load (RL) that can be connected to a low-voltage dc-voltage network, the circuit-breaker consisting of assemblies provided between input terminals and the load and said assemblies comprising a voltage monitoring unit (TVS1, R1), a current monitoring unit (Shunt, OPV), semiconductor switch units (MOSFET) and controllers (uC) associated therewith. According to the invention, a series circuit consisting of a TVS diode (TVS1) and a resistor (R1) is connected to the input terminals, the resistor having a connection to a first connector (1) of a microcontroller (uC) and the resultant voltage drop at the resistor providing the microcontroller with an overvoltage identification signal if a breakdown voltage is reached at the TVS diode as a result of an overvoltage. A second connector (2) of the microcontroller has a connection to a first semiconductor switch unit (MOSFET), the first semiconductor switch unit being in series, as an elongate switch, with the load (RL), and the microcontroller disabling the switch in the event of an overvoltage detection signal. A shunt acting as a current monitoring unit is in series with the load, the voltage drop at the shunt being analysed by the microcontroller via a third connector (3) and if an overcurrent which exceeds a threshold value is identified, the load is switched off by means of the first semiconductor switch unit. In addition, a MOS-gated thyristor (MGT) is connected between the input terminals, the control input of said thyristor having a connection to a fourth connector (4) of the microcontroller, such that the MOS-gated thyristor can be activated in the event of an overvoltage identification signal.
