Abstract
Disclosed is a hydraulic electromagnetic type breaker with arc-extinguishing function, which comprises a seat body as well as a manipulator, an armature, a moving contact, a fixed contact, a magnetic coil component, a lever mechanism, a load terminal and a connecting terminal arranged in the seat body, a magnet mounting frame is disposed at the outside of a shifting locus of the moving contact, and a pair of magnets with attracting magnetism are disposed above and below the magnet mounting frame. Because the magnet mounting frame is disposed at the outside of the shifting locus of the moving contact, a pair of magnets with attracting magnetism are disposed above and below the magnet mounting frame, the utility model utilizes the law of lorentz force, people know negative ions move towards the anode direction, and positive ions move towards the cathode direction, according to the left hand rule of the law of lorentz force, under the action of the same magnetic field, all ions (positive and negative ions) will move outwards from the contacts rapidly, thereby preventing the contacts and peripheral parts from being burnt, so the utility model is reasonable in structure, and can extend the service life of the breaker.
Description
[technical field]
The utility model relates to a kind of hydraulic electromagnetic breaker.
[background technology]
We know, circuit breaker has been widely used in the circuit control structure, and circuit breaker mainly contains two kinds of Thermomagnetic type and hydraulic-electromagnetics, and wherein hydraulic electromagnetic breaker can not be subjected to the variation of ambient temperature influence, advantage with reliability height and working stability is so its application is more and more popularized.But the dynamic and static contact of hydraulic electromagnetic breaker can produce a large amount of electric arc when moment disengages and disconnects, and electric arc burns out contact and parts on every side easily, must carry out the arc extinguishing measure for this reason, otherwise can reduce the useful life of circuit breaker greatly.
[utility model content]
The purpose of this utility model has provided a kind of hydraulic electromagnetic breaker of rational in infrastructure, the tool arc extinguishing function that can improve useful life.
In order to solve the technical problem of above-mentioned existence, the utility model adopts following technical proposals:
A kind of hydraulic electromagnetic breaker of tool arc extinguishing function, include pedestal and the executor, armature, moving contact, fixed contact, electromagnetic coil assembly, leverage, face terminals and the binding post that are arranged in the pedestal, outside described moving contact motion track, be provided with a magnet installing rack, be provided with the magnet that pair of magnetic is inhaled mutually at this magnet installing rack upper and lower.
In the improvement project to the hydraulic electromagnetic breaker of above-mentioned tool arc extinguishing function, described magnet installing rack is opening-like, and its bottom is installed in the slot of pedestal by fin.
In improvement project, on described magnet installing rack, be provided with the groove that is used for placing this magnet to the hydraulic electromagnetic breaker of above-mentioned tool arc extinguishing function.
Compared with prior art, the beneficial effects of the utility model are: owing to be provided with a magnet installing rack outside described moving contact motion track, on this magnet installing rack, the below is provided with the magnet that pair of magnetic is inhaled mutually, this is to utilize the principle of Lorentz force law to realize, we know that anion moves toward positive extreme direction, and cation moves toward the negative pole direction, left hand rule according to the Lorentz force law, under same the action of a magnetic field, all ions (just, anion) all can move outward from the contact apace, thereby contact and parts have on every side been avoided burning out, so of the present utility model rational in infrastructure, can improve the useful life of circuit breaker.
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
[description of drawings]
Fig. 1 is the stereogram of the utility model embodiment;
Fig. 2 is the part assembling schematic diagram of the utility model embodiment;
Fig. 3 is the arc extinguishing structure assembling schematic diagram of the utility model embodiment.
[embodiment]
The utility model is a kind of hydraulic electromagnetic breaker of tool arc extinguishing function, it includes pedestal 1 and the executor 2 that is arranged in the pedestal 1, armature 3, moving contact 4, fixed contact 5, electromagnetic coil assembly 6, leverage 7, face terminals 8 and binding post 9, circuit breaker is work like this: when manipulation device 2 makes circuit breaker work, moving contact 4 and fixed contact 5 contact, when overcurrent, electromagnetic coil assembly 6 produces enough big magnetic force armature 3 is inhaled in the past, armature 3 swing backs drive moving contact 4 by leverage 7 and leave fixed contact 5, at this moment can produce a large amount of electric arcs between them, outside described moving contact 4 motion tracks, be provided with a magnet installing rack 10, on this magnet installing rack 10 for this reason, the below is provided with the magnet 11 that pair of magnetic is inhaled mutually.
The utility model is to utilize the principle of Lorentz force law to realize; we know that anion moves toward positive extreme direction; and cation moves toward the negative pole direction; left hand rule according to the Lorentz force law; under same the action of a magnetic field; all ions (positive and negative ion) all can move from the contact apace outward; thereby contact and parts have on every side been avoided burning out; so rational in infrastructure, the useful life that can improve circuit breaker of the present utility model; and improve the electric current breaking capacity of circuit breaker greatly, guarantee protected circuit safety.
As shown in Figure 3, described magnet installing rack 10 is opening-like, and its bottom is installed in the slot 11 of pedestal 1 by fin 101, is provided with the groove 102 that is used for placing this magnet 11 on magnet installing rack 10.
Claims (3)
