Description
Technical field
The present invention relates to a kind of on/off switch operating mechanism of low-voltage circuit breaker, belong to the low-voltage circuit breaker technical field.
Background technology
Low-voltage circuit breaker claims again automatic switch, be the electric current under energy connection, carrying and the disjunction normal circuit condition, also can under improper circuit (for example short circuit, overload, the under-voltage) condition of defined, connect, carry a kind of device for switching of certain hour and breaking current.When making whole circuit be in improper circuit in the serious fault of the generations such as power circuit and motor, low-voltage circuit breaker can in time cut off circuit by the conversion operations between self close, the separating brake, thereby power circuit and motor are carried out protection.
The low-voltage circuit breaker realization is closed, the operating mechanism of separating brake generally is divided into manual-operating mechanism and motor-operating mechanism; in low-voltage circuit breaker far distance controlled field; general by motor-operating mechanism automatic brake separating and combined floodgate low-voltage circuit breaker, thus realization is to the protection of power circuit and motor.Motor-operating mechanism has two kinds in electric motor operating mechanism and operation electriomagnet mechanism, and motor-operating mechanism has advantages of that rotating speed can flexible, is to use at present many a kind of low-voltage circuit breaker motor-operating mechanisms.But when breaking down owing to motor-operating mechanism, also need to realize by manual-operating mechanism automatic brake separating and the combined floodgate of low-voltage circuit breaker, therefore, driving mechanism need to satisfy electric operating and manually operated function simultaneously.
The low-voltage short-circuiting device generally is to realize the on/off switch operation by following process: the frame at the on/off switch operating mechanism arranges actuated components, effector spare and driving shaft, described actuated components moves under the drive of motor, thereby drive the motion of effector spare, described driving shaft is subjected to the driving of effector spare and rotates, band dynamic circuit connector, the operation of separating brake running part, close, the separating brake running part is used in the masterpiece that driving shaft rotation produces on the switch knob of on/off switch operating mechanism, thereby drive the on/off switch operation of low-voltage circuit breaker.Wherein close, comprise connecting rod in the separating brake running part, described connecting rod rotates with the rotation of described driving shaft, touching moves after the frame of a side is prevented from, and after applying rightabout external force, described connecting rod moves in the opposite direction, touching moves after the frame of an other side is prevented from equally, and the setting of described connecting rod is moved described effector spare in the range of movement that limits.
Chinese patent literature CN201689848U discloses a kind of low-voltage electric leakage circuit breaker switching operating mechanism, be equipped with on its frame motor and by motor-driven driving gear and with the driven gear of driving gear engagement, the driven gear shaft of described driven gear forms swivel bearing by unilateral bearing and frame, driven gear shaft extends to the outer manually operated hand rotation section of being convenient to that forms of frame, be mounted with the rotating shaft rocking arm on the driven gear shaft, the position that described rotating shaft rocking arm departs from the driven gear shaft axis is provided with the pushing part, pushing away in the hole of push pedal stretched in the pushing part, push pedal is slidingly connected on the guide rod, and guide rod and frame are installed fixing.This switching operating mechanism need not electronic and manual switch just can realize electronic or manual operation, uses manual operation in the time of can breaking down at the electric operating of described operating mechanism or overhaul, thereby does not affect the normal operation of low-voltage circuit breaker system.But because driving gear and driven gear mesh together all the time in this operating mechanism, carrying out manually operated the time, be subjected to the restriction of driving gear and driven gear interlock, must overcome two gears owing to the resistance that engagement produces could be realized manual operation afterwards, so that manual operation is relatively required great effort.
Summary of the invention
