Latest Patents

One of Baumgärt's latest patents is an electronic tripping device for a circuit breaker. This innovative device contains circuitry that simulates the response curve of a fuse. It can be controlled by a single setting mechanism that represents the nominal or rated currents of fuses. This advancement improves the coordination of protection in sophisticated power supply equipment that utilizes both circuit breakers and fuses. The device achieves particularly safe operation by combining the setting mechanism with a rating plug for the "fuse" mode, allowing for direct setting to one current value. Additionally, the simulated curves may include a point of inflection below a limit in a lagging manner, which increases the nominal switching capacity and selectivity limit of a circuit breaker.

Another significant patent is a circuit arrangement for monitoring an electronic tripping device for low-voltage switches. This arrangement features a microprocessor device that evaluates an overcurrent in conjunction with a digital-analog converter. The microprocessor device includes a zero crossing comparator that transmits a constant test current pulse to the electronic tripping device via an additional current transformer winding. This setup allows for the measurement of amplitude and ensures that any deviations from the setpoint value trigger recalibration or actuation of the line tripping contacts, accompanied by an alarm signal.
