Description
The present invention relates to as the claim 1 a kind of arc extinguishing stack of laminations that is used to establish by cable and install especially for line protection switch and so on as described in the preamble.
The task of line protection switch, motor protection switch etc. is to connect so-called rated load; Necessary in addition cutting-off of short-circuit electric current, wherein, particularly line protection switch also has a task, is exactly limiting short-circuit current, so that so-called prospective short circuit current must not load network system.
Under line protection switch or motor protection switch situation; when opening circuit, can between activity and fixing contact, pull the trigger an electric arc; this electric arc is owing to the event of the ad hoc structure of contact point or because the event of electric field that certain measures for example produces by so-called blow-out loop; and be driven into from contact point the arc extinguishing stack of laminations, this arc extinguishing stack of laminations is to be combined by several laminations of arranging in parallel with each other and in a certain distance apart from one another.When electric arc enters such arc extinguishing stack of laminations when also claiming in the deionization stack of laminations, it just is divided into many and divides electric arcs, these minutes electric arc between per two arc extinguishing laminations adjacent to each other, burn.Because in the event of the voltage drop of relevant electric arc basic point, electric current just is limited and is eliminated.
In order to improve breaking capacity, can take a series of measure, above-mentioned blow-out loop is in these measures.Also having such possibility, is the both sides of the electric arc cup of being pulled the trigger therein at so-called cup exactly, settles some chamber plates, and the available in some cases material that sends gas of these chamber plates is made.Say following being suitable in principle: breaking capacity is big more, and then the arc quenching plate of settling in relevant stack of laminations is just many more.Because the spacing between the arc quenching plate must not be lower than certain minimum value, because otherwise because fusing is so can form little bead, also because deionization potential must not be lower than certain value, so the quantity of arc quenching plate can only increase like this, promptly the arc extinguishing stack of laminations is also occupied a bigger space generally.Because the shell of line protection switch does not allow to surpass certain height according to standard code; so that line protection switch still can adapt to the distribution board that sets for it; so the size of arc extinguishing stack of laminations is restricted; particularly when the arc extinguishing lamination is parallel to the stationary plane extension of line protection switch; as most applications, be restricted especially.
Also can take following measure to improve breaking capacity: not to be that a unique contact point is set, but two contact points are set; Can occur under the situation of these two contact points with corresponding higher breaking capacity situation under identical problem.

Since the structure of this bending of arc extinguishing lamination and since can be have between the very thin lamination insulating intermediate layer so, so obtained following advantage: come the more sheet of in an arc extinguishing stack of laminations, to pack into compared with the arc extinguishing stack of laminations that its arc extinguishing lamination is the plane.Owing under the condition of identical stack of laminations size, improved the number of arc extinguishing lamination, thereby can improve the breaking capacity of line protection switch or motor protection switch.
In the case, the arc extinguishing lamination of a bending and the arc extinguishing lamination on a plane can be arranged each other in contact or each other stackedly.Such possibility is arranged: only in abutting connection with a vertical seamed edge of two laminations, relative therewith, those lamination sections with normal separation are then in abutting connection with another vertical seamed edge for contact-making surface; Also have such possibility: each contact-making surface is alternately in abutting connection with these two opposite vertical seamed edges.
Another kind of scheme of the present invention is: all laminations are all in addition crooked; The sweep of the lamination that all are crooked is in the center of stack of laminations or departs from the center.
Can form insulation by the insulating coating in each lamination contact area; Also can do like this, i.e. contact pin in the shell of the switching device by holding stack of laminations forms insulation.In this case, lamination is directly guided in shell.
Can also so do,, thereby can form insulation by the respective tabs on the stack of laminations shell exactly for the arc extinguishing stack of laminations provides a stack of laminations shell.
