Definitions
- the present invention relates to a series of improvements introduced in the fuse bases with disconnection in load, unipolar or three-pole, in which the fuse cartridge used is of the "NH" type, affecting the improvements to both the cover and the handle associated with said cover, and which together form the fuse holder base mounted in an appropriate housing.
- the fuse bases are generally composed of a socket that is connected to the respective conductive bars, whose socket is related to a housing on which the fuse caps themselves are mounted, in which the cartridges or fuses are obviously held and retained. These caps they can occupy an operative or closing position in which the connection is established, or an inoperative or opening position corresponding to that of disconnecting the fuses. In an inoperative position, replacements of damaged fuses can be carried out, as well as the assembly / disassembly of both these and other parts that could be damaged and their exchange or replacement is necessary.
- each fuse is mounted in its own fuse holder cover, being able to perform the opening individually (single phase opening) or all three covers at the same time (three phase opening).
- each of the fuse holders has an individual handle, so that to make three-phase openings, that is to say the three fuses at the same time, elements and / or mechanisms that relate the three individual handles to each other are used, or a unique element by means of which the three covers are opened simultaneously.
- the improvements of the invention affect the fuse holders and the corresponding handles, being designed to obtain more versatile, simple and easy to handle fuse holders.
- One of the improvements consists in the fact that the fuse holder cover is constituted in such a way that it indistinctly admits the assembly or incorporation of a fixed handle, a retractable handle or even a three-pole disconnection system.
- the aforementioned cover also includes means for mounting and securing the fuse that are accessible from the outside of the cover, thus facilitating the assembly and disassembly of the fuses.
- the fixed handle and the retractable handle are constituted by a "U" profile, as a bridge, whose lateral branches are mounted on the cover by sliding in some recesses provided on the sides of said lid, presenting the lateral branches of the handles a free edge that ends in an oblique folding towards the inside and spherical surface.
- This spherical surface is complementary to another spherical surface provided in the lower part of the lateral recesses of the lid, such that the handle can rotate on the surfaces s which causes a flange provided on one of its lateral edges to be housed in a channel provided in one of the internal edges of the recesses of the sides of the lid. In this way it is achieved that the joint between the handle and the lid is a joint by way that allows to better withstand the sudden efforts in closing maneuvers in short circuit.
- the fixed handle also has internal nails in its lateral branches that are interlocked in notches provided on the front of the lid, in correspondence with the edges that form the side mounting recesses of the handle, so that the union of the Nails on the notches make the fixed handle cannot be removed.
- the retractable handle is exempt from the locking nails provided on the fixed handle to allow the handle itself to slide back and forth, so that it can occupy the operative or protruding position forward and the retracted or backward shifting, which corresponds to the inoperative position.
- the aforementioned retractable handle has at the edges of its sides a pair of intermediate notches and another pair of ramp notches in proximity to the transverse branch of the handle, so that the first pair of notches are provided to lock the handle in operative position, when the edges of the two sliding sliding parts mounted on front recesses of the cover fit into them, these locking parts being pushed by a kind of strapping outwards to fit in the aforementioned notches, such that a manual displacement of such Locking parts inwards allow them to be released from the aforementioned notches, making it possible to slide the handle to occupy the inoperative position.
- the aforementioned cover present in its front part a manually operated sliding part, which has a rear pin folded on itself, determining a wing as a strap that allows for deformation and elasticity the passage of a laminar portion or lug belonging to the fuse, so that it will be retained on the cover by blocking the said pin of the front sliding piece, once such pin has passed through the fuse lug, all this in such a way that to release the fuse it will be enough to move the sliding part laterally, causing the pin to move with respect to the lug and to constitute an obstacle for it, allowing the fuse to be removed from the cover.
- Another feature of novelty or improvement of the invention consists of means that relate two two fuse-bearing bases in parallel to each other, the means of which consist of a pair of threaded studs that are passed through respective holes facing and provided for the purpose in the adjacent sides of the handles corresponding to the two covers, these being blocked by respective threaded nuts on both ends of said studs, said means being complemented with respective spacer bushings mounted on the studs and interspersed between the two adjacent sides of the two referred handles.
- Another improvement of the invention consists in the way of manipulating the three fuse-holder bases to simultaneously disconnect the three phases, consisting in that the three covers pivotally relate to two common lateral stringers, transversely joined by a pair of handles.
- the pivotal assembly of the stringers to the cover is carried out by means of pins with a key provided in the stringers, which are housed in respective cylindrical collars provided in the respective covers, all so that they can pivot with respect to the stringers to effect disconnection and / or connection, although they are prevented from disconnecting from the stringers by virtue of precisely the keyed means incorporating the lugs and necks in which they are housed.
- Another characteristic of novelty consists in a means of blocking the covers, both in their open or disconnected position and in their closed or connecting position.
- This means is constituted by a transverse bridge provided in the intermediate cover, whose bridge has a configuration like that of the retractable handle but with three affected front lugs of as many holes for hooking of respective locks, which allows up to three different operators to work on the three-pole base and ensure that until each one does not open its lock, the three-pole base cannot accidentally change its operating position, avoiding accidents that could occur.
- a transverse and intermediate plate is provided between the stringers, a plate that is also provided with transverse ribs provided with holes that, in the closed position, face the lugs of the bridge constituting the intermediate retractable handle, to allow passage of the padlocks and lock the covers with respect to the stringers in the closed position, while in the open position the blockage will be carried out by means of the unfolding of said retractable handle, the lugs of the latter being inserted in oblique holes provided in the transverse plate e intermediate, and subsequently the padlocks in the holes of the lugs being thus immobilized and locked the assembly in an open or disconnected position, since the aforementioned handle cannot be retracted.
- Figure 1 Shows a representation according to an exploding perspective of a cover and the corresponding handle, which is provided with the internal nails on its sides so that its assembly is fixed or with respect to the aforementioned cover.
- Figure 2. Shows the assembly of the lid and handle represented in the previous figure.
- Figure 3. Shows a view according to an exploding perspective of the lid and the handle in the retractable version.
- Figure 4. Shows the assembly corresponding to the lid and handle represented in the previous figure.
- Figure 5. Shows a perspective view of two fuse bases in parallel, which are collaterally related to each other forming a unique set
- Figure 6. Shows a cross-sectional view of the two fuse holders, without the fuses, shown in the previous figure, showing the enlarged detail of the means that collaterally fix these two bases together.
- Figure 7. Shows a sectional detail of the means for holding a fuse with respect to the respective cover of the fuse holder base.
- Figure 8 shows a representation according to a perspective of the assembly of three fuse-holder bases related to each other through two lateral stringers with a pair of handles and an intermediate bridge. This figure shows the details corresponding to the pins with a key of the stringers and the complementary cylindrical housing collars for the same provided in the covers
- Figure 9. Shows the locking system of the plug bases in the operative position, the lock being made by means of three locks.
- Figure 10 shows a detail also in perspective of the means for blocking the fuse holders in the open or inoperative position.
- the fuse holder base on which the improvements of the invention are applicable comprise a cover (1) and a handle (2), which can be fixed, this corresponding to the reference itself (2) , or be a retractable handle, referenced with (2 ') -
- the cover (1) constitutes the means of mounting and securing the corresponding fuse (3), with the retention and / or release of such fuse (3) being carried out.
- a piece (4) mounted on the front of the cover (1) with lateral displacement power so that through its manipulation from the outside of the cover (1) it can be carried out the release and therefore the disassembly of the corresponding fuse (3), as will be explained later.
- This cover (1) has a pair of notches (5) on the edges corresponding to the front part, while in proximity to them and in correspondence with the front part itself it is affected by a pair of rectangular holes (6), in the sense transverse and open towards the sides, these having corresponding lateral recesses (7), which have a channel (7 1 ) in correspondence with one of the edges that limit each recess (7).
- the cover (1) also has cylindrical necks (8), whose function will be explained later, located in correspondence with one of the ends of its sides.
- the handle (2) that is fixedly mounted on the corresponding cover (1), has a "U" configuration and is mounted in the form of a bridge over the cover (1), counting the lateral branches (10 ) of said cover (2) with two internal nails (11), while inferiorly, that is, in correspondence with the free edges of its lateral branches (10) they have a fold (12) projected inwards and obliquely , determining a curved surface that is complementary to a curved surface edge (13) provided on the back of the side recesses (7) of the lid
- (11) determine a means of interlocking by being supported on the front of the lid (1), that is to say blocking of the handle (2) is achieved in its assembly on the lid
- the handle (2 ') can be mounted on the corresponding cover (1) in a retractable way, in which case said handle (2') has the aforementioned lateral wings (10), with the edge turned inwards (12), being in this case free of the locking nails (5), also having the eyelashes (14), the step (15) and the eyelashes (14 '), of greater amplitude than the previous ones.
- the lateral wings (10) of the handle (2 1 ) have an approximately intermediate height with a pair of recesses (16), and another pair of recesses in ramp (17), all this so that in operative position for said retractable handle (2 '), the folded edge inwards (12) is locked in the spherical edge (13) of the cover (1), while in the lateral recesses (16) the outer edges corresponding to the pieces (9) located on the recesses (6) of the cover (1), counting those parts (9) with an elastic and internal element as a strap that constantly pushes outwards in its position on the corresponding recess (6) , allowing the accommodation of the outer edge of the pieces (9) in the recesses mentioned (16), in order to achieve the blocking of the handle (2 ') in the operative position.
- the fuse holder base described can be provided for the individual disconnection of each of the phases involved in an assembly, where logically there are three fuse bases, or they can be provided for the simultaneous disconnection of the three phases, or what is same opening of the three fuses simultaneously, so that for the latter case it has been provided that the three bases (1), as shown in Figure 8, are pivotally mounted on a pair of lateral stringers (26) determining a common frame for the three covers (1), each of which can pivot independently them or simultaneously, these covers being mounted by accommodation in their cylindrical necks (8) of respective lugs (27), with a key (28), provided for the purpose in the stringers (26), so that the lugs ( 27) with their keys (28) they are complementary to the holes (8) allowing the assembly of each of the covers (1) between the stringers (26) with the possibility of tilting them, but impossible to detach from the stringers ( 26), which are connected to each other by means of a pair of bridges (28) determining the corresponding handles whose manipulation or manual grip allows the beams (26) to rotate
- the three-phase solution referred to is complemented by means that allow blocking both in the open position and in the closed position, for which it is provided that the intermediate cover (1) has a handle (30) of similar characteristics to the handles (2 ) and (2 ') referred to previously, with the particularity that said handle
- (30) is retractable but equipped with three lugs (31) on its forehead, in which many other locks (32) can be introduced that allow up to three different operators to work on the three-pole base and guarantee that until each one does not remove his padlock the three-pole base cannot accidentally change its operative position.
- a cross plate (33) provided with transverse ribs (34) affected by holes (35) facing the holes provided in the lugs (31) of the crossbars (26) is also provided in the intermediate zone (26).
- retractable handle (30) so that the locks (32) can pass through these holes and through those of the lugs, immobilizing the stringers (26) with respect to the covers (1), preventing their opening, as it is represented in figure 8 and in the enlarged detail corresponding to figure 9.
- the opening position can also be locked or immobilized, for which once the frame that forms the stringers (26) is pulled, swinging the covers (1) and therefore carrying out the opening or disconnection, it will suffice with which the handle (30) that in the previous position was retracted, is removed, causing the lugs (31) to be introduced into the windows (36) established for that purpose in the plate (33), to carry out the coupling of the padlocks (32), as shown in figure 10, the handle (30) being maintained without being able to be retracted and therefore maintaining the opening position of the covers (1).
