Latest Patents
Lindeperg's latest patents include a Limiting Circuit Breaker and a Solid-State Instantaneous Trip Device for a Current Limiting Circuit. The Limiting Circuit Breaker features a Thomson effect propelling device that facilitates the opening of contacts. This design includes a main contact bridge that is securely united to an operating rod, which is surrounded by an annular opening coil of the propelling device. The device also incorporates an opening disk that moves in relation to the rod, with springs positioned between the disk and an annular piston to ensure the disk returns to its rest position after the opening travel.
The Solid-State Instantaneous Trip Device is designed with two threshold values, providing both an upper and a lower tripping threshold. It includes a current increase rate detector that assesses the prospective peak current value during a short-circuit event. If the peak value is likely to exceed the electrodynamic withstand of the circuit breaker, the device changes the threshold to enable tripping as soon as the lower threshold is surpassed. This high-speed tripping mechanism is effective in limiting short-circuit currents, while also allowing for tripping selectivity under less severe short-circuit conditions.
