Abstract

The invention discloses a horizontal permanent magnetic mechanism breaker. The breaker comprises a frame, vacuum switch tubes arranged on the frame in parallel, two permanent magnetic driving mechanisms with push rods, a rotation shaft, two separating brakes and six breaking-closing brake crank arms. The push rods of the permanent magnetic driving mechanisms are horizontal and are vertical to the moving directions of moving and static contact breaking-closing brakes of the vacuum switch tubes to form a horizontal structure. The rotation shaft is arranged in the frame in a rotatable mode, the middle ends of the crank arms are sleeved and fixed on the rotation shaft, the lower ends are in rotatable connection with the push rods of the permanent magnetic driving mechanisms through hinge pins, and the upper arms are connected with the bottom ends of insulation pull rods through hinge pins. The vacuum switch tubes are arranged along the plumb line directions, the static contacts are arranged on the upper portions, and the movable contacts are arranged on the lower portions. The portions of the static contacts, which stretch out of the top ends of vacuum switch tube casings are fixed with and electrically connected with upper power connection plates. By means of the breaker, the whole height can be reduced effectively, and the breaker is in accordance with the miniaturization development trend.

Description

technical field [0001] The invention belongs to the technical field of structural design of a permanent magnet mechanism circuit breaker in a coal mine explosion-proof power distribution system, and in particular relates to a horizontal permanent magnet mechanism circuit breaker. Background technique [0002] At present, the high, medium and low voltage circuit breakers and contactors in the coal mine explosion-proof power distribution system generally include three vacuum switch tubes and a vertical permanent magnet drive mechanism for synchronously driving the three vacuum switch tubes to open and close synchronously. The type permanent magnet drive mechanism generally realizes synchronous driving of multiple vacuum switch tubes through the shaft lever technology or by turning the crank arm. The former needs to increase the overall height of the circuit breaker, and its technology is difficult and immature; the latter needs to increase the guide device to realize linear dr...
