Description
Technical field
The utility model relates to a kind of adjustable Thermomagetic circuit-breaker, and especially a kind of pyromagnetic adjustable circuit breaker is improved with electromagnetic tripping apparatus, is to regulate the scalable that reaches Thermomagetic circuit-breaker by electromagnetic tripping apparatus.
Background technology
At present mainly bright 2, the contact system 3 of the construction of switch (as depicted in figs. 1 and 2) of common non-adjustable circuit breaker, overcurrent trip 4 by arc quenching system 1, hand, transmission mechanism is formed, because whole switch part is more, complex structure; But defencive function is single, must corresponding one by one rated current, do not satisfy actual needs and market demands, and make use cost higher;
Have the dealer to develop the electronic type adjustable circuit breaker, it has overload protection characteristics and short-circuit protection characteristic simultaneously for this reason.But, prove that there are various unsteadiness (promptly anti-action, misoperation) in the electronic type adjustable circuit breaker according to field feedback in the last thirty years.Therefore, at present the electronic type adjustable circuit breaker that uses of user is foreign brand name entirely.For example: companies such as Siemens, ABB, Schneider and Mitsubishi, home brands electronic type adjustable circuit breaker occupation rate of market is almost nil.
Summary of the invention
In order to overcome above-mentioned defective, the utility model provides a kind of pyromagnetic adjustable circuit breaker to improve with electromagnetic tripping apparatus, and the adjustable structure that this electromagnetic tripping apparatus improvement increases is simple, reliability is high and cost increases less.
The utility model for the technical scheme that solves its technical problem and adopt is: a kind of pyromagnetic adjustable circuit breaker is improved with electromagnetic tripping apparatus, comprise that every utmost point has a Motionless electromagnetic member, it is by the current excitation that flows through conductor, and mobile armature, it is attracted to this Motionless electromagnetic member, with this trip gear action of this actuating, be provided with a rotating shaft, rotating shaft articulates on the support, support is fixed in body, be provided with pushing block below the rotating shaft, the quantity of pushing block and mobile armature, the position is complementary, rotation by rotating shaft, pushing block can be passed mobile armature and move toward Motionless electromagnetic member direction, rotating shaft is provided with a shoulder, support is provided with a knob again, periphery forms the boss that is the asymptotic reduction of circular arc below the knob, the boss below is a shoulder, rotation forward or backwards by knob boss is slowly pressed down or on remove shoulder, at this moment rotating shaft in opposite directions or dorsad mobile armature is rotated, pushing block slowly pass mobile armature in opposite directions or dorsad the Motionless electromagnetic member move, regulate mobile armature and the Motionless electromagnetic member distance in gap between the two with this.
Be provided with two supports, be individually fixed in the body both sides, the rotating shaft two ends are articulated in corresponding support respectively.
The beneficial effects of the utility model are: electromagnetic tripping apparatus is the mechanism of a flat overcurrent of the instantaneous height of response.Do not having under the situation of abnormal current, each mobile armature leaves relevant Motionless electromagnetic mechanism by a spring bias voltage, form the gap between mobile armature and the Motionless electromagnetic mechanism part, this example is by adjusting the size in described gap, realizing the adjustable of Thermomagetic circuit-breaker; This example is come the described gap of fit adjustment by rotating shaft, pushing block, knob and boss, can adapt to the different different instantaneous protections of instantaneous protection electric current, tool, and adjustable structure is simple, stable work in work and cost are lower.

Embodiment
Embodiment: a kind of pyromagnetic adjustable circuit breaker is improved with electromagnetic tripping apparatus, comprise that every utmost point has a Motionless electromagnetic member, it is by the current excitation that flows through conductor, and mobile armature 1, it is attracted to this Motionless electromagnetic member, with this trip gear action of this actuating, be provided with a rotating shaft 2, (support is respectively established in the body both sides usually on the rotating shaft pivot joint support 3, the rotating shaft two ends articulate corresponding support respectively, rotating shaft just can freely be rotated between two stands like this), support is fixed in body, be provided with pushing block 4 below the rotating shaft, the quantity of pushing block and mobile armature, the position is complementary, can pass mobile armature by the rotation pushing block of rotating shaft moves toward Motionless electromagnetic member direction, rotating shaft is provided with a shoulder 5 (shoulder generally is located at the rotating shaft side), support is provided with a knob 6 again, periphery forms the boss 7 that is the asymptotic reduction of circular arc below the knob, the boss below is a shoulder, rotation forward or backwards by knob boss is slowly pressed down or on remove shoulder, at this moment rotating shaft in opposite directions or dorsad mobile armature is rotated, pushing block slowly pass mobile armature in opposite directions or dorsad the Motionless electromagnetic member move, regulate mobile armature and the Motionless electromagnetic member distance in gap between the two with this.
Course of action of the present utility model is: turn the instantaneous protection electric current down as need; rotation by knob makes boss slowly press down shoulder; at this moment rotating shaft is rotated toward the mobile armature direction, and pushing block is slowly passed mobile armature and moved toward Motionless electromagnetic mechanism part direction, dwindles both clearance distances with this.As enlarge the instantaneous protection electric current just conversely.(in this example, when knob changeed clockwise, boss slowly pressed down shoulder, and rotating shaft is rotated toward the mobile armature direction, and pushing block is slowly passed mobile armature and moved toward Motionless electromagnetic mechanism part direction; When knob changeed counterclockwise, boss was slowly upwards away from shoulder, and rotating shaft mobile armature direction is dorsad rotated, and pushing block is slowly away from mobile armature, and mobile armature is toward moving away from Motionless electromagnetic mechanism part direction.)
Therefore, this example reaches the response of different abnormal currents by regulating the gap between mobile armature and the Motionless electromagnetic mechanism part, promptly reaches the different transient current protections that require.
