The current conductors are designed as a one-piece, homogeneous rail.

Description

The invention relates to a fuse bar or load bar for NH (low-voltage high-performance) fuses, also referred to as NH fuses inserts.

In such strips power converters can be used, which serve to measure the current in the fuse strip or load switch bar. Depending on How many phases are to be measured, one or more current transformers use. The measurement of the phases can be done permanently without power interruption. The current transformer (s) are installed inside the fuse or load breaker strip and wired to a transducer in the terminal compartment of the fuse or load-breaker strip and / or a multi-pole terminal or plug connector. The strip is especially required in connection with NH fuses for fuse protection and switching of circuits. The bar is further required, for example, to lead out the auxiliary circuits of an auxiliary switch for switching position displays, a transmitter in remote display, an electronic fuse monitoring. Transducers are used to electronically capture electrical data of the fuse or enter detected electrical variables directly to the device. They are designed, for example, as measuring devices or evaluation electronics.

A fusebox or fuse switch for NH fuses, comprising a housing, contacts arranged on a front side of the housing for receiving the fuses, wherein the contacts are connected to current conductors and the current conductors pass through recesses in the housing, and the respective arrangement of contact and current conductors in the housing is stored, wherein at least one arrangement of contact and conductor is associated with a current transformer, and the arrangement of contact and conductor passes through an opening of the current transformer, is from the AT 004111 U1 known.

In this known strip a current conductor is approximately Z-shaped and has substantially mutually parallel end portions and a middle section connecting them. At least one of the two parallel sections is connected to the middle section, preferably detachably connected, in order to be able to plug the current transformer onto the power section in the region of the central section. For example, the middle section is bolted to one of the parallel sections. As a result, the bar can in principle be retrofitted with the current transformer. Of particular disadvantage in this case, however, that of the power line serving conductor is to be separated here. Subsequent equipment of the bar with the current transformer is thus associated with a considerable effort, regardless of the high safety requirements to be complied with concerning the current-carrying components.

It is also known to arrange current transformer separately to fuse strip or load switch bar for NH fuses. This is to accommodate the or the current transformer with respect to the fuse or load selector bar separate device carrier bar use, as for example in the DE 297 05 224 U1 or the DE 10 2007 051 419 A1 is illustrated. These devices are therefore basically intended for the inclusion of current transformers and therefore do not aim at a design of the fuse or load switch bar for retrofitting with at least one current transformer.

It is finally out of the DE 199 13 017 A1 known to assign a current transformer directly to the NH fuse-link. Here, the NH fuse-link is a special component with shortened trained insulator, depart from which the two contact blades of the NH fuse-link, one of the contact blades longer than in a comparable NH fuse-link formed and therefore is suitable to receive a current transformer , This is thus not current-carrying components of the bar, but current-carrying components of the fuse link, specifically associated with the contact blade of the fuse link.

The object of the invention is to provide a fuse or switch-disconnector according to the AT 004111 U 1 so-called type so that they can be retrofitted without dismantling this bar as a whole or parts of the bar with one or more current transformers in a simple manner.

The object is achieved in that the arrangement of contact and conductor has a Aufsteckbereich for front-mounting the current transformer on the arrangement of contact and conductor, wherein the cross section of the opening of the current transformer is greater than the cross section of the arrangement of contact and conductor in Aufsteckbereich.

Under front here is the operator of the fuse strip or load switch bar facing side of the bar or the housing of the bar understood.

Accordingly, the bar can be easily provided with the current transformer not only in the initial installation, but it is also possible with mounted bar retrofitting this bar with the current transformer. This is because the arrangement of contact and conductor has the Aufsteckbereich for front-side plugging the current transformer to the arrangement of contact and conductor. Since the cross section of the opening of the current transformer is larger than the cross section of the arrangement of contact and current transformer in Aufsteckbereich, the current transformer can be easily pushed onto the arrangement of contact and conductor. The indication of the cross section of the opening of the current transformer or the cross section of the arrangement of contact and conductor refers to a viewing direction in Aufsteckrichtung of the current transformer, whereby the cross-sectional area of the opening of the current transformer must be greater than the cross-sectional area of the envelope of the arrangement of contact and conductor in the Aufsteckbereich and the cross-sectional dimensions in the two perpendicular to the direction of attachment extending spatial directions of the opening of the current transformer must be greater than the cross-sectional dimensions of said envelopes.

Seen outside the Aufsteckbereichs the arrangement of contact and conductor in the direction of the rear portion of the bar, these mentioned comparison cross sections are not required because in this, to the Aufsteckbereich subsequent area of the arrangement of contact and conductor, the current transformer does not get.

Due to the selected formulation of the arrangement of the contact and the current conductor, the plug-on region for the current transformer can, for example, only be in the region of the contact, or else only in the region of the current conductor. This allows a variety of designs of the bar and different arrangements of the or contacts with respect to the housing of the bar. If the current transformer is plugged only on the contact, the cross-sectional configuration of the contact according to the invention is taken into account and the cross-sectional configuration of the conductor arbitrarily, while plugging the current transformer via the contact on the conductor, the inventive cross-sectional configuration for contact and conductor, thus the arrangement of Contact and conductor, to be considered.

Due to the inventive design of the bar any number of contacts or any number of conductors can be equipped with current transformers. Preferably, the contacts are equipped with the current transformers.

It is provided in particular that the strip has three current phases and each of the three arrangements of contact and conductor is associated with a current transformer. These three current transformers are used in particular for permanent current measurement and work together with an electricity meter. It is quite possible to assign a further current transformer to one phase, thus assigning two current transformers to the two arrangements of contact and conductor of this phase, the further current transformer serving, for example, as a display device in the context of a suburban measurement. Bars can therefore also have two or four current phases.

Preferably, in the respective, the current transformer having arrangement of contact and conductor, the conductor can be connected to a busbar. Accordingly, the current transformer is associated with the conductor of the bar, through which the power of the bar is supplied. In principle, it would also be possible to assign the current transformer to one of the outgoing current conductors of the strip.

The current conductor of the respective arrangement of contact and conductor is designed in particular as a one-piece, homogeneous rail. This rail is thus formed in one piece, in particular bent, preferably in the manner of a Z. The rail is not composed of individual parts which are screwed together, soldered, welded and the like.

In structurally simple design, the rail has a rectangular profile, which is Z-shaped. It thus turns out to be a profile that is bent twice in opposite directions by 90 °.

Of particular importance is the formation of the respective contact of the fuse strip, which should be suitable for plugging a current transformer. The contact is designed in particular substantially U-shaped, with substantially parallel legs and a web connecting them, wherein the web is connected to the conductor, in particular the rail.

This connection is made in particular by screwing, riveting, Verclinchen, welding of conductors, in particular rail with the web of the contact.

The essentially U-shaped design of the contact makes it possible to place the current transformer on the contact due to the cross-section of the current transformer which does not change substantially, the legs passing through the opening in the current transformer. The substantially parallel legs clamp an envelope which is rectangular so as to provide an opening in the current transformer that is rectangular, but slightly larger than the envelope provided by the two Leg of the contact is formed. If possible, the rectangular opening in the current transformer should be dimensioned so large that when, with the two legs of the contact, a spring is connected to allow in this case the plugging of the current transformer to the contact. Basically, this is not necessary because before attaching the transducer, the spring could be removed and connected again after attaching the transducer with the thighs.

In this aspect, an advantageous embodiment of the invention provides that the contact has two legs and a web connecting them, wherein the web is connected to the conductor, in particular the rail, wherein the contact further comprises the spring mounted in the two legs, in particular a spring formed as an open ring, wherein the spring counteracts a bending away of the legs.

The contact is preferably designed such that it has, in Aufsteckrichtung of current transformer and NH fuse, a current conductor adjacent the first portion for receiving the current transformer and a remote from the current conductor second portion for receiving a contact blade of the NH fuse. In this case, the contact thus serves to accommodate NH fuse and current transformer.

Alternatively, the contact may have a section for receiving a contact blade of the NH fuse and the current conductor having a section for receiving the current transformer. - In this case, the contact serves to receive the contact blade, while the current conductor is used to accommodate the current transformer.

In both different solutions can be provided that the contact has a stop for limiting the insertion movement of the contact blade of the fuse link. This stop can be realized by using a spring mounted in the two legs, for example be that the insertion movement of the contact blade is terminated when applied to the spring. Alternatively, one or the other legs of the contact may be provided with a projection which limits the insertion movement of the contact blade.

The strip according to the invention is characterized in that the or the current transformers are mounted from the front of the bar, without any disassembly operations on the bar or components of the bar are made. This front-side mounting of the respective current transformer allows a simple and uncomplicated and also structurally less expensive attachment of the connecting cables to the current transformer or wiring of the current transformer. Thus, according to an advantageous development of the invention, it is provided that the housing has at least one channel for receiving connection lines to the at least one current transformer. In particular, the channel is open to the front of the bar. The respective current transformer to be mounted is either initially attached to the arrangement of contact and conductor and then wired, the connecting cables are inserted into the channel or it is plugged the already provided with the connection cables current transformer to the arrangement of contact and conductor and, at the same time or but later, the connecting cables inserted into the channel. The channel may in this case be designed as a collecting channel, i. In the outgoing area of the connection cables from the housing, all connection lines of the current transformers are arranged in one channel.

In the mounted position of the respective current transformer, it is preferably arranged such that the current transformer plugged onto the arrangement of contact and current conductor covers the channel open to the front side of the strip. As a result, on the one hand, the connecting lines are fixed in the channel, on the other hand, the connection lines in the channel below the current transformer are not accessible.

According to a preferred embodiment of the invention it is provided that a cover element for a conductor has a removable, in particular breakable cover plate for the conductor. When the cover plate is removed, its rating plate is visible when the current transformer is plugged in.

The current conductors are in particular arranged outside the channel extending in the housing. This ensures contact protection from the channel to the conductors. The connection lines of the converter are led out of this in particular in the region of an end face of the strip and out the current conductors for the current outlets in the region of the opposite end sides of the bar out of this. This design is under the aspect of contact protection of particular advantage. The circuit of the bar is separated from the circuit of the converter.

Further advantages, features and possible applications of the present invention will become apparent from the following description of two embodiments and the accompanying drawings of the figures.

The in the FIGS. 1 to 12 illustrated bar is designed as a load breaker strip 1 for three non-illustrated NH fuses. The strip 1 has a housing 2 and arranged on a front side 3 of the housing 2 contacts 4 for receiving the fuses. Two contacts 4 each serve to receive a fuse, with which the strip 1 has six contacts 4. The contacts 4 are connected to current conductors 5 and 6, respectively. The current conductors 5 are each assigned to a contact 4 of a phase, the current conductors 6 are assigned to the other contact of the respective phase. The respective current conductor 5 is Z-shaped and thus has mutually parallel end portions 7 and 8 and a the two end portions 7, 8 connecting central portion 9. The central portion 9 increases with respect to the end portions 7 or 8 each a right angle. The respective current conductor 5 is formed as a one-piece, homogeneous rail.

The elongate housing 2 is provided with three recesses 10 which pass through the housing 2. While the current conductors 5 are formed identically, the current conductors 6 are formed differently long according to their positioning in the housing 2. The current conductors 6 have identical end sections 11 and 12. The middle section 13 connecting the end section 11 and the end section 12 is of different length in the case of the respective current conductor 6. The end portions 11 and 12 of the respective current conductor 6 are arranged parallel to each other. Also, the respective current conductor 6 is formed as a one-piece, homogeneous rail.

The respective contact 4 is designed substantially U-shaped. It essentially indicates, i. largely parallel legs 14 and a connecting web 15 on this. In the web 15 a plurality, in particular two threaded holes are introduced, for screwing the contact 4 in conductive connection with the end portion 8 of the conductor 5 and the end portion 12 of the conductor 6, further for securing the arrangement of contact 4 and conductor 5 or contact 4 and 6 current conductor on one of the front side 3 facing wall 16 of the housing. The fastening used for an arrangement illustrated screws 17th

Each of the three current phases are thus associated with two contacts 4, a current conductor 5 and a current conductor 6, wherein the current conductor 5 passes through the housing 2 to the rear and the end portion 7 of the conductor 5 of contacting this conductor 5 with a busbar of a busbar system and also the Connection of this conductor 5 is used with this busbar. For connecting the end portion 7 of the conductor 5 is provided with a slot 18. An unillustrated screw passes through this and it is the conductor 5 screwed to the busbar.

The respective other current conductor 6 is guided by the associated contact 4 to the front end 19 of the housing 2. The end portions 11 of these current conductors 6 are positioned in the region of the end 19. They have holes 20 for connecting the current conductors 2 with unillustrated outgoing connecting lines. The end portions 12 of the current conductors 6 are formed corresponding to the end portions 8 of the current conductor 5 and serve the current-conducting connection with the three associated contacts 4 and the attachment of the arrangement of contacts 4 and current conductors 6 in the region of the wall 16 of the housing. 2

The respective contact 4 has a spring 21 mounted in the two legs 14 and designed as an open ring. The annular spring 21 is open to the front side 3 and lies with its two ends on opposite sides of the legs 14 in recesses of the legs 14, so that the spring 21 is securely mounted in the legs 14. From these bearing points, the spring extends in the direction of the web 15 of the contact 4. This spring 21 counteracts a movement apart of the legs 14 of the contact 4. The contact has a stop for limiting the insertion movement of a contact blade of the NH fuse-link. This stop is effected for example by the region of the spring 21, which faces the web 15 of the contact 4. Alternatively, one of the legs 14 of the contact 4 may be provided with a protruding into the insertion of the contact blade projection, which thus limits the insertion movement of the contact blade.

Due to this length of the legs, this contact 4 is suitable for functionally accommodating not only the plug-in contact blade of a NH fuse-link, but between the contact-receiving portion of the contact 4 and the web 15 of the contact 4 also take a current transformer 22. First, thus, the current transformer 22 is placed on the legs 14 of the contact 4 in the vicinity of the web 15 and then the NH fuse-link with his contact blade introduced into the contact 4, thus inserted between the two legs 14 of the contact 4 against the force of the spring 21. The respective contact 4 thus has, in Aufsteckrichtung of current transformer 22 and contact blade of the NH fuse, a portion 23 for receiving the contact blade and a portion 24 for receiving the current transformer 22. In this case, the contact 4 passes through an opening 25 in the current transformer 22. Accordingly, the arrangement of contact 4 and associated current conductor 5 or current conductor 6 has a Aufsteckbereich 38 formed by the sections 23 and 24 for attaching the front of the current transformer 22 to the arrangement of contact 4 and Conductor 5 or conductor 6, in the specific embodiment of the contact 4 on. The cross-section of the opening 25 of the current transformer 22 is in this case greater than the cross section of the arrangement of contact 4 and conductor 5 and the current conductor 6 in Aufsteckbereich 38, in the concrete embodiment of the cross section of the contact 4, as he through the envelope of the two legs, in Aufsteckrichtung seen, results. The goal is that the current transformer 22 can be completely plugged onto the contact 4, and it is not necessary here to disassemble the contact 4, in particular it is not necessary to remove the spring 21 from the contact 4.

The bar 1 thus has three current phases and it is, in particular to FIG. 2 illustrates each of the three current phases associated with a current transformer 22. Specifically, the current transformer 22 is attached to the contact 4, which is connected to the current conductor 5. These three current transformers 22 are used for continuous current measurement. Illustrated in the FIG. 2 with dashed lines a further current transformer 22 associated with a phase, which thus cooperates with a contact 4 which is connected to a current conductor 6. This current transformer 22 serves to measure the current and display the measured current directly in the region of the strip 1.

Each of the current transformers 22 is wired. The housing 2 has lateral channels 27 for receiving connection lines 28 to the current transformers 22. These channels 27 are open to the front side 3 of the housing 2. The two connection lines 26 for a current transformer 22 are connected to the current transformer 22 by means of terminals (see embodiment Fig. 13 ) and guided to an end face of the housing 2 through the channel or channels 27, to the end 29 of the housing 2, which faces away from the end 19.

The connecting lines 28 are thus led out in a region of the bar 1, which is opposite to the region of the housing 2, in which the current outlets, thus the current conductors 6, are led out of the bar 1. The current conductors 5 and 6 extend outside the channels 27.

Regardless of whether the load switch bar 1 is used with or without current transformer 22, covers 30 are provided for each of a pair of contacts 4, which are associated with a current phase. Each cover 30 has two hoods 31 and a plate 32 connecting these two hoods 31. In the region of each hood 31 on the side facing the other hood 31, the plate 32 has a removable, in particular breakable, relatively small cover plate 33, below which the current transformer 22 plugged into the associated contact is positioned in its region next to the contact 4 , In order to recognize that the load switching strip 1 is equipped with a current transformer 22 in the region of the respective contact 4, this cover plate 33 is removed, whereby there a substantially rectangular hole 34 is formed, through which the data concerning the technical specification of the current transformer 22, which are printed on the top of the current transformer 22, are visible. This is for example in FIG. 4 illustrated for arranged in the region of the end 29 of current transformer 22.

With the housing 2, a strip upper part 26 can be locked on the front side 3, this takes three pivot cover 37 pivotally. Each pivot cover 37 serves to receive an NH fuse-link, which is pivoted when pivoting the pivot cover in the two contacts 4 of the respective current phase of the bar 1.

The embodiment of the FIG. 13 different from those after the FIGS. 1 to 12 only by the changed design of the arrangement of contact 4 and 5 current conductor or conductor 6 and the positioning of the current transformer 22 with respect to this arrangement. In this embodiment, the respective contact 4 does not have the extra long length, as described for the first embodiment, but is shorter in Aufsteckrichtung of the current transformer 22, so that the contact 4 only serves to receive the contact blade of the fuse link. At the in FIG. 13 Specifically described embodiment, the current conductor 5 is positioned in the region of a substantially cuboid projection 35 of the housing 2, whereby the central portion 9 of the conductor 5 is applied to a side surface of the projection 25 or positioned at a small distance to this and the end portion 8 of the conductor 5 on the upper surface of the projection 35 rests, thus the surface which is associated with the front side 3 of the strip 1. In this case, it must be ensured that the cross section of the arrangement of contact 4 and current conductor 5, thus the cross section of this arrangement over the entire insertion of the current transformer 22 to almost the end portion 7 of the conductor 5 is smaller than the cross section of the opening 25 of the conductor 22nd The Aufsteckbereich 38 extends in this embodiment from the front end of the contact 4 to the central portion 9 of the conductor 5 adjacent to its end portion. 7

In the FIG. 13 the connection terminals for the connection lines of the current transformer 22 are designated by the reference numeral 36.
