| 51 | Circuit breaker for hierarchically controlling short-circuit current and trips | US15233949 | 2016-08-10 | US09633811B2 | 2017-04-25 | Xin Li; Bochen Li; Bolin Li |
| The invention discloses a short circuit current hierarchical control tripping parameter circuit breaker. According to the invention, resistance of an alloy magnetic resistance body is changed through circuit current, and contract control can be carried out on short-circuit current. The control range of the circuit breaker can achieve that no magnetic resistance will be generated when current is no more than 8 times of rated operational current, and current limiting may be realized by the magnetic resistance when current is 8 times more than rated value. In this way, hierarchical control on short-circuit current of different levels of circuits can be carried out, and short-circuit current can be limited in a predetermined range, thereby restricting the short-circuit current in a predetermined range, solving a problem of power supply flickering, and avoiding large-area power failure accidents caused by override trip existing in an electrical control switch. | ||||||

The mechanism has a central piezoelectric actuator that extends to pull contacts inwards in order to obtain two disconnects within a millisecond or less. Surrounding the piezoelectric actuator is a polymer insulating shell and beyond the shell is the metallic conductor. | ||||||

An actuator is energized to move the pair of switching contacts, closing the gap between one of the fixed contact pads and one of the switching contacts, thereby causing conducting liquid droplets to coalesce and form an electrical circuit. At the same time, the gap between the other fixed contact pad and the other switching contact is increased, thereby causing conducting liquid droplets to separate and break an electrical circuit. The actuator is then de-energized and the switching contacts return to their starting positions. The volume of liquid metal is chosen so that liquid metal droplets remain coalesced or separated because of surface tension in the liquid. The relay is amenable to manufacture by micro-machining techniques. | ||||||
