Abstract
The utility model discloses an intelligent standby tripping protecting device for a breaker, which includes a bracket on a pedestal of the breaker, a rotatable armature is arranged on the bracket, the armature is positioned on the upside of a conductive board of the breaker, one side of the armature bends down to form a stress bearing piece, the other side of the armature forms a contact arm, the contact arm can prod the transmission mechanism of the breaker. The utility model uses the electromagnetic field generated when the conductive board transmits current to drive the rotatable armature, and the motion of the armature can drive the transmission mechanism of the machine body to cause the breaker to open the brake for protecting the circuit.
Description
Technical field
The utility model relates to a kind of circuit breaker, particularly a kind of reserve dropout protective device of intellectual circuit breaker.
Background technology
Intellectual circuit breaker is the control signal that produces by intelligent controller, triggers intelligent electrical apparatus release and makes the circuit breaker disjunction, thereby circuit breaker is shielded to the line fault at place.The main course of action of intellectual circuit breaker is: current transformer detects the electric current by circuit breaker; when electric current breaks down; signal is sent to intelligent controller and carries out computing; and corresponding results is sent to intelligent electrical apparatus release by controller; be transferred to the transmission mechanism of breaker mechanical body again by release; finally make breaker open operation, the disengagement failure circuit, thus realize short-circuit protection, overload protection and earth leakage protective.
When having especially big electric current to pass through in the circuit, the operation principle of circuit breaker is the same the same, the disjunction that can not be exceedingly fast response, and this moment, big electric current had serious risk to line security.
Summary of the invention
The utility model purpose is: provide a kind of when have in the circuit breaker especially big electric current by the time play the device of reserve dropout protective effect, can make circuit breaker disjunction in a flash, with protection circuit.
The technical solution of the utility model is: a kind of reserve dropout protective device of intellectual circuit breaker; comprise the support on the pedestal that is fixed on circuit breaker; support is provided with rotatable armature; armature is positioned at the top of the conductive plate of circuit breaker; be bent to form stressed under one side direction of armature; the opposite side of armature is formed with contact arm, and contact arm can be stirred the transmission mechanism of circuit breaker.
The further technical scheme of the utility model is: a kind of reserve dropout protective device of intellectual circuit breaker, comprise the support on the pedestal that is fixed on circuit breaker, support is provided with rotatable armature, armature is positioned at the top of the conductive plate of circuit breaker, be bent to form stressed under one side direction of armature, the opposite side of armature is formed with contact arm, and contact arm can be stirred the transmission mechanism of circuit breaker; On support, bearing pin is with spring outward to described armature by the bearing pin pin joint, and an end of spring is connected with support, and the other end of spring is connected with armature.
The more detailed technical scheme of the utility model is: a kind of reserve dropout protective device of intellectual circuit breaker, comprise the support on the pedestal that is fixed on circuit breaker, support is provided with rotatable armature, armature is positioned at the top of the conductive plate of circuit breaker, be bent to form stressed under one side direction of armature, the opposite side of armature is formed with contact arm, and contact arm can be stirred the transmission mechanism of circuit breaker; On support, bearing pin is with spring outward to described armature by the bearing pin pin joint, and an end of spring is connected with support, and the other end of spring is connected with armature; The below of described armature is provided with yoke, and yoke is installed in the conductive plate outside.
The utility model advantage is:
1. the electromagnetic field that produces when the utility model utilizes conductive plate to pass live stream drives rotatable armature, is transferred to the transmission mechanism of basic machine again by armature movement, can make the circuit breaker separating brake that is exceedingly fast, with protection circuit.
2. the utility model is provided with yoke below armature, and yoke is installed in the conductive plate outside, promptly adds yoke in electromagnetic field, has increased magnetic attraction, has played the effect that drives the armature rotation better.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1 is enforcement figure of the present utility model;
Fig. 2 is a structural representation of the present utility model.
Wherein: 1 support; 3 stressed in 2 armature; 4 contact arms, 5 bearing pins; 6 springs, 7 yokes; 8 conductive plates.
Embodiment
Embodiment: as depicted in figs. 1 and 2, a kind of reserve dropout protective device of intellectual circuit breaker, comprise the support 1 on the pedestal that is fixed on circuit breaker, be connected with armature 2 by bearing pin 5 on the support 1, armature 2 is positioned at the top of the conductive plate 8 of circuit breaker, be bent to form stressed 3 under one side direction of armature 2, the opposite side of armature 2 is formed with contact arm 4, and contact arm 4 can be stirred the transmission mechanism of circuit breaker; Be with spring 6 outside the bearing pin 5, an end of spring 6 is connected with support 1, and the other end of spring 6 is connected with armature 2; The below of armature 2 is provided with yoke 7, and yoke 7 is installed in conductive plate 8 outsides.
When in the circuit big electric current being arranged, conductive plate 8 produces stressed 3 action that magnetic fields are magnetized yoke 7 and attracted armature 2, thereby makes contact arm 4 stir the transmission mechanism of circuit breaker, and transmission mechanism drives the circuit breaker separating brake that is exceedingly fast.After separating brake was finished, contact arm 4 resetted under the effect of spring 9.
The utility model can be adjusted the counter-force of spring 6 in different circuits, makes it be applicable to different current specification.
Below only be concrete exemplary applications of the present utility model, protection range of the present utility model is not constituted any limitation.In addition to the implementation, the utility model can also have other execution mode.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop within the utility model scope required for protection.
