    摘要: A power circuit breaker includes break contacts for main current circuits and a connection device for auxiliary current circuits that interacts with a contact device mounted in a fixed manner. Signaling switches are placed on a withdrawable rack, which accommodates the power circuit breaker, and are provided for detecting and signaling the position of the power circuit breaker located inside said withdrawbable rack. The signaling switches are structurally assigned in a direct manner to an interface subassembly that processes signals, which are transmitted out of the contact device and by the signaling switches and to be relayed to a field bus system.

    摘要: A circuit arrangement for detecting the current of a current conductor in order to activate electronically controllable tripping devices, having a line voltage supply unit, with the operating voltage generated by the line voltage supply unit being compared to a reference voltage and the tripping device being activated by a limit voltage that forms when an overcurrent occurs. The a.c. voltage transmitted via secondary phase windings is rectified and supplied to a microprocessor device in the form of an operating voltage by the phases that are not in the measuring state. The processor-controlled phase measurement is performed without load, producing a precise measurement result.

    摘要: A method and circuit arrangement for measuring a current are described, which can be used in electrical engineering to precisely trigger electronic tripping devices in circuit breakers. The current is measured according to magnitude and phase in such a way that only the fundamental wave of the current between precisely determined current zero crossings is sampled at a low sampling rate, and the root mean square is calculated on the basis of the measured phase angle and amplitude. The exact phase angle is measured using a conventional PLL circuit with a downstream zero switch.

    摘要: A rating plug may be provided with an electrical coding such that unsuitable identification of the rating plug is not transmitted to the trigger unit, but rather the attempt to make use of such a rating plug leads to a signal. The signaling unit is arranged on the housing of the low-voltage power breaker, or on the trigger unit. Thus, if the rating plug is the wrong rating plug, wrong contact connection and a defective rating plug may be recorded.

    摘要: An electronic tripping device for a circuit breaker contains circuitry for simulating the response curve of a fuse. This circuitry can be controlled by a single setting mechanism representing the nominal currents or rated currents of fuses. This improves the coordination of protection in sophisticated power supply equipment containing both circuit breakers and fuses. Tripping devices equipped with microprocessors or operating in an analog fashion can be configured for the mode of operation. The new protection system achieves particularly safe operation for the user in that the setting mechanism is combined with a rating plug for the “fuse” mode, thus directly setting the tripping device to one current value. In a manner similar to a true fuse, consequently, the setting mechanism is provided with appropriate labeling. The simulated curves may contain a point of inflection below a limit in a lagging manner, to increase the nominal switching capacity and selectivity limit of a circuit breaker.

    摘要: A method is for preventing tapping into existing short circuits in branches. A power supply momentarily is connected in a test circuit at a defined instant of the power supply voltage and at least the current in the test time period is detected and evaluated as a criterion for a short circuit. The short-circuit current is limited by the use of an additional test resistor which is arranged in the test circuit in series preferably with a semiconductor switch. Solely the test current and/or the test voltage is used for identification of the short circuit. In the associated arrangement, a test resistor having a defined resistance, whose resistance is significantly greater than the power supply impedance, is arranged in the test circuit in series with the semiconductor switch.
