Abstract
The utility model discloses a C-shaped magnet increasing sheet which comprises an opening part, a connecting part and a closed part, wherein the connecting part is located at the two ends of the closed part, the opening part is connected with the two ends of the connecting part far away from the closed part, the opening part, the connecting part and the closed part form a C-shaped structure with a recess together in a surrounding manner, and the width of the opening part is more than that of the connecting part, so that the width of the recess on the connecting part is more than that of the recess on the opening part. The number of the C-shaped magnet increasing sheet (sheets) is one or more, and the C-shaped magnet increasing sheet can be in a split structure or integrated structure. The C-shaped magnetic increasing sheet provided by the utility model has a simple structure, and since the magnetic increasing sheet can control the distribution of magnetic lines of force, then the magnetic lines of force can be concentrated on the part where an electric arc exists. When the electric arc is located in the middle of the magnetic lines of force of the magnetic increasing sheet, the denser the magnetic lines of force is, the larger the Lorentz force on the electric arc is and the higher the moving speed of the electric arc is.
Description
Technical field
The utility model relates to a kind of " C ", and type increases magnetic sheet, belongs to the arc quenching system field of circuit breaker.
Background technology
Circuit breaker is a kind of device for switching that is applied in distribution network be used for distributing electric energy, protection circuit and power-supply device, and the closed and disconnected of the dynamic and static contact of dependence is realized connection and the disjunction of electric current.When overload or short circuit current while occurring, the circuit breaker operation mechanism action, separately, electric arc produces dynamic and static contact.Extinguish arcs is to weigh an important indicator of circuit breaker fast.
The extinguishing process of electric arc is broadly divided into two sections, and the one, be formed to before electric arc moves into arc control device from electric arc, the 2nd, after electric arc enters arc control device.To be formed to electric arc from electric arc to move into arc control device effective arc extinguishing means before by increasing the magnetic sheet arc extinguishing.But the magnetic sheet structure that increases of the prior art is as shown in Figure 4 " U " type, and what have increases the magnetic sheet structure that is formed in one, and what have is as shown in Figure 5 split-type structural.The air gap that this " U " type structure increases in magnetic sheet is larger, and more sparse by the magnetic line of force of air gap, magnetic field intensity is little, thereby causes arc quenching effect undesirable.
The utility model content
For the problems referred to above that " U " type structure that increases magnetic sheet in prior art exists, type structure that the utility model provides a kind of " C " increase magnetic sheet.
The technical solution of the utility model is:
A kind of " C " type increases magnetic sheet, comprise peristome, connecting portion and closure, described connecting portion is positioned at respectively the two ends of described closure, described peristome is connected away from the two ends of closure respectively with on connecting portion, described peristome, connecting portion and closure enclose jagged " C " type structure on one side jointly, the width of described peristome is greater than the width of connecting portion, so that the notch width at connecting portion place is wider than the notch width at peristome place.
As further improvement of the utility model, the quantity that described " C " type increases magnetic sheet is one or more pieces.
As further improvement of the utility model, described " C " type increases the magnetic sheet structure that is formed in one.
As further improvement of the utility model, it is split-type structural that described " C " type increases magnetic sheet, and namely peristome, connecting portion and closure are individual components.
The beneficial effects of the utility model are:
The utility model a kind of " C " type increases the simple in structure of magnetic sheet, and this increases the control of magnetic sheet by the magnetic line of force is distributed, and the magnetic line of force is concentrated on the part that electric arc exists.Electric arc is positioned in the middle of the magnetic line of force that increases magnetic sheet, and the magnetic line of force is more intensive, and the Lorentz force that electric arc is subject to will be larger, and the translational speed of electric arc is just faster.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
The structure that the utility model a kind of " C " type increases magnetic sheet as shown in Figure 3, comprise peristome 1, connecting portion 2 and closure 3, connecting portion 2 lays respectively at the two ends of described closure 3, peristome 1 is connected away from the two ends of closure 3 respectively with on connecting portion 2, peristome 1, connecting portion 2 and closure 3 enclose " C " type structure that recess 11 is arranged jointly on one side, the width of described peristome 1 is greater than the width of connecting portion 2, so that recess 11 width at connecting portion 2 places are wider than recess 11 width at peristome 1 place.The quantity that " C " type of being somebody's turn to do increases magnetic sheet is one or more pieces.It can be split-type structural that " C " type of being somebody's turn to do increases magnetic sheet, and namely peristome 1, connecting portion 2 and closure 3 are individual components, can be also integrated formed structures.As can be seen from Figure 1, should " C " type increase magnetic sheet and contain different cross-sectional areas.
The utility model a kind of " C " type increase in magnetic sheet the Distribution of Magnetic Field situation as shown in Figure 2, the vertical paper of the sense of current in figure is inwards.As seen from Figure 2, " C " type increases the little place of air gap 9 of magnetic sheet 5, and the magnetic line of force 8 is concentrated, and the also zone that exists of electric arc just of this part.
As shown in Figure 1, whole magnetic blow-out system comprises three parts to the use state that the utility model a kind of " C " type increases magnetic sheet, and namely moving contact 4, " C " type increase magnetic sheet 5 and fixed contact 6." C " type increases magnetic sheet 5 and is enclosed within on fixed contact 6, and the electric current of fixed contact 6 motivates magnetic field in the middle of " C " type increases magnetic sheet 5, and the magnetic line of force in magnetic field passes the electric arc 7 between moving contact 4 and fixed contact 6.
The utility model a kind of " C " type increases the simple and practical of magnetic sheet, and this increases the control of magnetic sheet by the magnetic line of force is distributed, and the magnetic line of force is concentrated on the part that electric arc exists.As shown in Figure 2, the air gap hour in increasing magnetic sheet, the magnetic line of force can become intensive, and magnetic field intensity is large, and the air gap in increasing magnetic sheet is when large, and it is sparse that the magnetic line of force can become, and magnetic field intensity is little.Electric arc is positioned in the middle of the magnetic line of force that increases magnetic sheet, and the magnetic line of force is more intensive, and the Lorentz force that electric arc is subject to will be larger, and the translational speed of electric arc is just faster.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model.All any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection range of the present utility model.
