Abstract
The utility model discloses a backup protection tripping device of an electronic moulded case circuit breaker, which is mainly applied to the B-phase superheavy current short circuit protection of an electronic moulded case circuit breaker. The backup protection tripping device of an electronic moulded case circuit breaker comprises a circuit breaker operating mechanism, a connecting rod and a backup protection tripper, wherein a drawing rod is arranged on the circuit breaker operating mechanism. The connecting rod is arranged between the drawing rod and an armature and articulated with the circuit breaker operating mechanism, and both ends of the connecting rod are respectively buckled with the armature and the drawing rod, thereby the backup protection tripper applied to a B phase of the utility model and backup protection trippers applied to the traditional A phase and the C phase can not be positioned on the same straight line but are positioned in a staggered way, the interference of the circuit breaker operating mechanism is avoided and the space is left for the installation of the backup protection tripper on the B phase; and accordingly, when both the A phase and the C phase have backup short circuit protection, the backup short circuit protection of the B phase can be also realized.
Description
Technical field
The utility model relates to a kind of back-up protection tripping device of electronic type molded case circuit breaker, is mainly used in the especially big short circuit current protection of electronic type molded case circuit breaker B phase in the prior art.
Background technology
Electronic type molded case circuit breaker is the control signal that produces by intelligent controller; the control release makes the circuit breaker disjunction; thereby make circuit breaker play the effect of protection circuit; but; when having especially big short circuit current to pass through in the circuit; electronic breaker disjunction fault is as quick as thought carried out route protection effectively.
Therefore; in the prior art; generally in electronic type molded case circuit breaker, install electromagnetic type backup protection release additional; realization is to the quick disjunction of especially big short circuit current; this electromagnetic type backup protection release generally comprises armature; support; the yoke of fixedlying connected with the circuit breaker base; bearing pin and reaction spring; described armature is hinged by bearing pin and support upper end; yoke is then fixedlyed connected with the lower end of support; reaction spring is socketed on the bearing pin; and the two ends of this reaction spring are connected with armature and support respectively; circuit breaker A; backup protection release on the C two-phase is installed all in the following manner: two connecting portions promptly are set respectively on armature and draw bar accordingly; to realize mutual snapping between armature and the draw bar; then when having unusual especially big short circuit current; because armature and yoke adhesive; the rotation of armature affects draw bar to rotate; make circuit breaker operation mechanism thread off; realize the quick disjunction of circuit breaker; hence one can see that; on the draw bar the compartment of terrain be provided with two and be respectively applied for A; the connecting portion that electromagnetic type backup protection release armature is interlockingly connected on the C two-phase; then for the low capacity electronic type molded case circuit breaker; because the restriction of installing space; can't be again according to A; electromagnetic type backup protection release mounting means carries out the installation of B phase backup protection release on the C two-phase; therefore; in the prior art, the B of circuit breaker does not possess especially big short circuit current protection.
Summary of the invention
The present invention is directed to the deficiencies in the prior art; a kind of back-up protection tripping device of electronic type molded case circuit breaker is provided; it is by being provided with connecting rod between circuit breaker operation mechanism draw bar and electromagnetic type backup protection release; and the two ends of this connecting rod are interlockingly connected with draw bar and this electromagnetic type backup protection release armature respectively; realization is to the quick disjunction of especially big short circuit current, thereby circuit is played protection.
For realizing above technical purpose, the utility model will be taked following technical scheme:
A kind of back-up protection tripping device of electronic type molded case circuit breaker; comprise the draw bar and the backup protection release that are arranged on the circuit breaker operation mechanism; described backup protection release comprises armature; support; the yoke of fixedlying connected with the circuit breaker base; bearing pin and reaction spring; armature is hinged by bearing pin and support upper end; yoke is then fixedlyed connected with the lower end of support; reaction spring is socketed on the bearing pin; and the two ends of this reaction spring are connected with armature and support respectively; also be provided with connecting rod between described armature and the draw bar; the described connecting rod body of rod is articulated on the circuit breaker operation mechanism, and the two ends of this connecting rod are interlockingly connected with draw bar and armature respectively.
Described connecting rod is V-shaped, and two openends of this V-arrangement connecting rod are interlockingly connected with draw bar and armature respectively, and its closed bottom end is then hinged with circuit breaker operation mechanism.
The closed bottom end of V-arrangement connecting rod is hinged by locating shaft and circuit breaker operation mechanism.
According to above technical scheme, can realize following beneficial effect:
The utility model is by being provided with connecting rod between draw bar and armature; this rod hinge connection is on circuit breaker operation mechanism; and the two ends of connecting rod are interlockingly connected with armature and draw bar respectively; therefore; can backup protection release described in the utility model can be installed mutually at the B of electronic type molded case circuit breaker; the backup protection release and the A of the prior art that avoid B to go up mutually; backup protection release on the C two-phase is located along the same line; be backup protection release and the A of the prior art that B goes up mutually; backup protection release on the C two-phase is placed mutually with misplacing; avoided the interference of circuit breaker operation mechanism; give the installation leaving space of the backup protection release that B goes up mutually; therefore; at A; when C possesses the reserve short-circuit protection mutually, can also realize the reserve short-circuit protection of B phase.

Embodiment
Explain the technical solution of the utility model below in conjunction with accompanying drawing.
As shown in Figures 1 to 3; the back-up protection tripping device of electronic type molded case circuit breaker described in the utility model; comprise circuit breaker operation mechanism 1; connecting rod 4 and backup protection release; this circuit breaker operation mechanism 1 is provided with draw bar 2; connecting rod 4 then is hinged on the circuit breaker operation mechanism 1; described backup protection release comprises armature 51; support 53; the yoke 52 of fixedlying connected with the circuit breaker base; bearing pin 55 and reaction spring 54; described connecting rod 4 is V-shaped; and two openends of this V-arrangement connecting rod 4 are interlockingly connected with draw bar 2 and armature 51 respectively; its closed bottom end is then hinged with circuit breaker operation mechanism 1; and the closed bottom end of this V-arrangement connecting rod 4 is hinged by locating shaft and circuit breaker operation mechanism 1; described armature 51 is hinged by bearing pin 55 and support 53 upper ends; yoke 52 is then fixedlyed connected with the lower end of support 53; reaction spring 54 is socketed on the bearing pin 55, and the two ends of this reaction spring 54 are connected with armature 51 and support 53 respectively.
During operate as normal, the reaction force of spring makes yoke 52 and armature 51 separately; When busbar has big especially short circuit current to pass through, can produce an electromagnetic field, make yoke 52 and armature 51 adhesives, because yoke 52 is fixed on the base, armature 51 rotates forward and beats on connecting rod 4, connecting rod 4 rotates and then stirs draw bar 2 actions, makes circuit breaker operation mechanism 1 thread off, and realizes the quick disjunction of circuit breaker.
