摘要： A protective device is disclosed having a circuit breaker for an electrical connection between a transformer and a load, wherein an overcurrent device is arranged between the transformer and the load. The overcurrent device has first magnetoelectric transducers arranged at each phase conductor and the neutral conductor, wherein the overcurrent device uses the transducer currents to in each case establish the presence of a first ground-fault current, and wherein the circuit breaker has a switching device, which interrupts at least the phase conductors between the transformer and the load in the event of the presence of a first ground-fault current (unrestricted earth fault). In order to also be able to determine the ground fault current between the transformer and the circuit breaker, at least one embodiment of the invention proposes providing in each case second magnetoelectric transducers at each phase conductor, the neutral conductor and a star-point conductor which is connected to the star point, using the transducer currents of the second transducer in each case to determine the presence of a second ground-fault current (restricted earth fault), and forming a signal for disconnecting the transformer in the event of the presence of a second ground-fault current.

摘要： A trip device is for an electrical power breaker, for tripping on a short-circuit. It is embodied as an analogue electrical circuit. The circuit components and devices necessary for tripping on a short circuit form a discrete module, completely independent of other trip devices on the power breaker. A direct current is provided by transformers together with rectifiers which flows through a power semiconductor switched to conduct in the normal operating state of the power breaker. A measurement and control circuit is controlled by way of a voltage generated across a measuring resistance through which the direct current flows and closes the power semiconductor when a threshold value is exceeded. The current is then commutated from the power semiconductor to the trip magnet which opens the switch contacts with a particularly small delay.

摘要： One embodiment of the present invention discloses a method for the automatic adjustment of a protective device having an excess-current release, particularly a low-voltage circuit breaker, which includes an asynchronous motor as a load, said motor requiring protection from overload, and also protects the energy distribution system from a short circuit, wherein at least one release time Tp is to be set as a parameter on the excess-current release, the time ensuring that thermal overload of the asynchronous motor does not occur. In order to enable an automatic adjustment of the excess-current release, the invention proposes that the integral of the square of the motor current over the time be determined based on the temporal current progression of the asynchronous motor at a given load, particularly at nominal load, after connecting or reversing, and that from the integral the trigger time of the excess-current release is derived, in that the integral corresponding to the heating of the asynchronous motor is placed in relation to a predetermined multiple of the square of the nominal current, wherein the motor current progression includes at least the starting current, the transition, and the self-adjusting motor nominal current.
