Abstract

The invention relates to the technical field of circuit breakers, and particularly relates to a rapid closing circuit breaker and a circuit breaker group. The circuit breaker comprises an outer shell,a handle mechanism, a tripping transmission mechanism, a magnetic tripping mechanism and a thermal tripping mechanism; the outer shell comprises a supporting base and a cover plate, the cover plate is arranged on the supporting base, and the handle mechanism is located on an upper portion of the supporting base and used for manually opening and closing the circuit breaker; the tripping transmission mechanism is located on an upper left portion of the base, and the tripping transmission mechanism and the handle mechanism are matched through a U-shaped transmission rod to achieve tripping and buckling; the magnetic tripping mechanism is arranged in the support base and is positioned below the handle mechanism; the thermal tripping mechanism is arranged on the support base and is positionedat a left lower part of the magnetic tripping mechanism; and a bottom contact point of the tripping transmission mechanism is positioned between the magnetic tripping mechanism and the thermal tripping mechanism. The circuit breaker has advantages that force storage is realized, closing efficiency is improved, closing synchronism of multiple circuit breakers is increased, and power utilization safety is improved.

Description

technical field [0001] The invention relates to the technical field of circuit breakers, in particular to a fast closing circuit breaker and a circuit breaker group. Background technique [0002] Existing miniature circuit breakers generally have short-circuit and overload protection functions. Once short-circuit or overload occurs, the circuit breaker will trip. For circuit breaker trip indicating device and circuit breaker. The trip indication device includes: a magnetic trip link, rotatably fixed on the shaft of the trip actuator of the circuit breaker; a first fault indication marking area exposed by a first window on the housing of the circuit breaker; and a second trip indicator arranged side by side with the first trip indicator, having a protrusion, and having a A second fault indication marking area exposed through a second window on the housing of the circuit breaker. When the circuit breaker is magnetically tripped, the first and second fault indication mark ar...
