Embodiment
Referring now to accompanying drawing, introduce according to the embodiment of low-voltage circuit breaker of the present invention, identify with Reference numeral 1.
With reference to figure 1, circuit breaker 1 comprises the first shell 10, the corresponding movable contact (not shown) that it is holding at least one fixed contact 20 and is engaging and depart from described fixed contact 20 between the first closed circuit position and the second open-circuit position, and transmission mechanism (not shown), be operatively associated with described movable contact.Described transmission mechanism can have normally used type in these application, so will not introduce in detail below.
In addition, in described shell, place at least the first splicing ear (not shown), for example, be connected electrically to described fixed contact 20 by the splicing ear of fixed contact 20, and the second splicing ear 30, be connected electrically to described movable contact.
Be according to one of exclusive feature of circuit breaker 1 of the present invention, it comprises arc chamber 40, is positioned at described fixed contact 20 and has between first end 51 that described the second splicing ear 30 is electrically connected and the conducting element 50 (electric arc guiding element) of the second end 52 of ending at base 53.As following will be more apparent, conducting element 50 has formed preferred circuit element for electric arc, during open circuit step, prevents that electric arc from approaching movable contact.
Described arc chamber 40 comprises the conductive plate 41 of multiple shapings, inserts between the second end 52 of described fixed contact 20 and described conducting element 50.Circuit breaker 1 according to the present invention also presents body 60, comprises that sealing ferromagnetic material makes magnetic pole second insulation crust 61 of (not showing because being enclosed in shell 61 inside).Body 60 is positioned near the conductive plate 41 of described multiple shapings, and define described movable contact during mobile between described the first closed circuit position and the second open-circuit position for its current space 65.
In fact, described movable contact is during moving between described closed circuit position and open-circuit position (vice versa), and it is inner mobile in space 65.Under closed circuit condition or in the time that electric arc exists, due to electric current mobile in circuit and exist the galvanomagnetic effect of magnetic pole (ferromagnetic element of body 60) to attract movable contact towards open-circuit position, thereby contribute to make open circuit operation speed-raising.
With reference to figure 3 and Fig. 4, under conductive plate 41 preferable case of shaping, be substantially parallel to each other.More preferably in situation, according to illustrated embodiment, the conductive plate 41 of shaping presents quadrangle profile substantially, with the first base limit 411 and second top margin 412 relative with described first side 411.On described top margin 412, advantageously make recess 413, in embodiment shown in the figure, it is V-arrangement substantially.
The structure of the recess 413 in the conductive plate 41 of various shapings makes under preferable case, and the end of the recess 413 of the conductive plate 41 of each shaping point 414 is positioned at the same plane with the planar quadrature at conductive plate 41 places of described shaping.In other words,, in the situation that recess 413 is V-arrangement, regardless of opening and the degree of depth of recess, the lower summit of V-arrangement recess is all positioned at the same plane with the planar quadrature at plate 41 places.
With reference to figure 1 and Fig. 2, under the degree of depth preferable case of the position of these plates and/or these recesses, make the end point 414 of the recess 413 of the conductive plate 41 of each shaping entirely not be positioned on straight line, but connected by broken line.As from accompanying drawing, when the end point 414 of recess 413 arranges (described distance is corresponding to the gradient of conductive plate 41 positions that are shaped) and along arranging gradually with the orthogonal second direction of first direction gradually along first direction, in this sense, at least from certain point forward, this broken line is downward.
Can realize this point by the relative position that changes the degree of depth of recess 413 and/or the conductive plate of shaping 41.With reference to accompanying drawing, under this latter event, the conductive plate 41 being particularly advantageously shaped comprises more than first the conductive plate 41a being shaped, its base limit 411 is positioned at same cardinal plane, and more than second the conductive plate 41b being shaped, its base limit 411 is arranged pro rata about described cardinal plane in the direction on the base 53 of described second end 52 of described conducting element 50.Under preferable case, the top margin 412 of the conductive plate 41a of the shaping of more than first plate is also positioned at the same top plane parallel with described cardinal plane, and the top margin 412 of the conductive plate 41b of the shaping of more than second plate is arranged pro rata about described top plane in the direction on the base 53 of described second end 52 of described conducting element 50.
From practical perspective, by making can realize with the following methods this point: for more than first plate 41a, the conductive plate (consistent size each other) being shaped is at identical relative position continuous arrangement, for more than second plate 41b, the conductive plate being shaped with constant gradient but different height arrange, arrange pro rata along same direction.
For example, with reference to accompanying drawing, from approaching most the position of fixed contact 20, the first partial assembled of the plate 41 of more than first plate 41a (for example three plates 41) has identical size and dimension (comprising the size and dimension of recess 413).Be second partial assembled (being follow-up four plates 41) of the plate 41 of more than first plate 41a subsequently, but they have identical size different shapes, and recess 413 is deepened gradually.Finally, what follow is the plate (being three plates in example) of more than second plate 41b, and they are with different height placement, proportional in the distance on base 53 of the second end 52 that moves closer to conducting element 50.
By this way, from fixed contact 20, the space that the recess 413 of the conductive plate 41 of shaping limits is bending gradually in the direction on the base 53 of the second end 52 of conducting element 50.In fact,, as from Fig. 1 and Fig. 2, about the sectional view of circuit breaker 1, the terminal part of the second end 52 of fixed contact 20 and conducting element 50 (base 53) is with different height placement.This contributes to significantly for electric arc provides preferred path, prevents that it from approaching current collector, brings the contingency question of its wearing and tearing.
Facilitate in situation, for example, by being equipped with the first insulation board 45 and second insulation board 46 of first jockey (hole) that can for example, connect with corresponding the second jockey (excrescence) being positioned on conductive plate 41 relative sides of described shaping, plate 41 is wrapped in therebetween, they are pre-assembled in together.But, other forms of assembling is also possible.
With reference to figure 1, under preferable case, in described the first shell 10, define the bearing that holds arc chamber 40, described bearing presents diapire, this diapire with the first surface (because it is hiding and invisible to be insulated plate 45) of contiguous described fixed contact and contiguous described first surface and in the direction on the base 53 of the second end 52 of conducting element 50 about the second surface 12 of its inclination.This just allow conductive plate 41 of being shaped hold in bearing favourable and in place easily.
In addition, under preferable case, define at least one raceway groove 15 in the first shell 10, enclosure is communicated with outside, the entrance position 16 of described raceway groove 15 is positioned near the second end 52 of conducting element 50.By this way, the gas producing along with the generation of electric arc is easily discharged into outside shell 10, has reduced the risk of the equipment that infringement circuit breaker 1 and shell 10 inside hold.
Specifically, with reference to figure 3, under preferable case, body 60 is essentially U-shaped, with the first arm 63 and the second arm 62, is parallel to each other and is connected by the 3rd perpendicular arm 64.So in this case, be limited between described the first arm 63 and the second arm 62 and be open upwards in the side of described fixed contact 20 for the current space 65 of described movable contact, and the 3rd arm 64 is in the face of described conducting element 50.
In addition, under preferable case, body 60 presents support surface 66, to be supported at least on the top margin 412 of the conductive plate 41 being shaped described in some; Support surface 66 presents protuberance 67 easily, the space that the recess 413 that is suitable for making in the top margin 412 of the conductive plate 41 that is inserted in described shaping limits.
In fact find with experimental technique, due to the galvanomagnetic effect of previously having introduced, with regard to the open circuit speed of movable contact, this structure is particularly favourable.
From operation viewpoint, movable contact is positioned at about the conductive plate 41 of multiple shapings and the position that is all close to about fixed contact 20 in the time of the first closed circuit position, in the time of the second open-circuit position, be positioned at about the conductive plate 41 of described multiple shapings and about described fixed contact 20 all away from position.In other words,, during open circuit mobile (i.e. passing through from the first closed circuit position to the second open-circuit position), substantially according to the direction of arrow in Fig. 1 100, movable contact is all removed from described fixed contact 20 with from the conductive plate 41 of described multiple shapings.Because the concrete structure of arc chamber (shape, size and the position of the conductive plate 41 of shaping) and fixed contact 20 be tending towards pilot arc on the rightabout about arrow 100 with the mutual alignment of the second end 52 conducting element 50, so further reduced electric arc and approach the risk of movable contact.
As seen from the above description, the set goal and object are realized completely according to low-voltage circuit breaker of the present invention.
Exactly, the open circuit that comprises the existence permission contact of the body 60 of ferromagnetic element moves acceleration.By the structure of arc chamber 40 and by shape and the position of its assembly, make electric arc approach movable contact and the risk minimization damaging gradually or immediately to its certainty.
Also must emphasize, native system comprises in fact a series of partial assembled (body 60; The conductive plate 41 and the insulation board 45 and 46 that are shaped; Fixed contact 20 and movable contact; Conducting element 50), they are relatively easily manufactured and assemble.
According to provided explanation, other features, modification or improvement are possible and apparent to those skilled in the art.So these features, modification and improvement should be regarded as the part of this model.In fact, according to demand and state-of-art, material used and possible size and form can be any.
