Description
Low Voltage High Current Switching System
[0001] The present invention relates to the field of low voltage, high current electrical switch distribution of the type for domestic or industrial street distribution, and in particular, discloses a multiway link switch.
[0002] Any discussion of the background art throughout the specification should in no way be considered as an admission that such art is widely known or forms part of common general knowledge in the field.
[0003] Examples of such low voltage, high current switching systems are disclosed in United States Patent 6252187 entitled "A Link Switch", PCT application PCT/AU2001/001394 and Australian Patent 2013222000, the contents of each are incorporated by cross reference.
[0004] Electrical power distribution systems for distribution of electricity to household and industrial premises or the like often rely on switching elements to switch electricity along cables that can be underground cables or above ground.
[0005] In AC distribution systems, power is normally transformed from a generator source to a high voltage (say 11 kilovolts), distributed to the vicinity of the load where it is down transformed to a lower voltage level suitable for use (say 400, 240 or 110 volts). Between the transformer and load can be a number of switching devices.
[0006] Further, often the electrical distribution is by what of bulky multicore sector cables, with three separate phase sector cables and a neutral cable being required for power distribution. Each sector cable can be of a solid or stranded form. These cables are often bundled together with an outer sheath and placed underground parallel to the ground, with the cables bent through a right angle, and bundled together when entering the bottom of a switch. Often these cables are extremely difficult to manipulate.
[0007] Importantly, it is often necessary to be able to switch a load from one source to another with minimal disruption.
[0008] It is an object of the invention, in its preferred form to provide an improved form of low voltage, high current cable switching system.
[0009] In accordance with a first aspect of the present invention, there is provided a low voltage, high current switching system including: a series of phase switches, with each phase switch switching three sector cables between a series of distribution cables; each phase switch further including: a series of conductive block portions having profiled surfaces which, in conjunction with adjacent conductive block portions form a cavity for the insertion of an activation switch, with the activation switch having a surface for conductively interconnecting adjacent conductive block portions within a cavity; at least one of the conductive block portions including a distribution unit for conductively interconnecting a series of distribution cables for distribution of electrical services from the system; and a series of conductive sector cable clamping units each conductively interconnected to at least one corresponding conductive block portion, the sector cable clamping units including clamping means for conductively clamping a sector cable; wherein the insertion of the activation switches into the cavities act to switch power from predetermined ones of the conductive sector cable clamping units to the distribution unit.
[0010] In some embodiments, at least two of the conductive block portions can include distribution units and the activation switches act to switch power to each of the distribution units.
[0011] In some embodiments, the series of phase switches are preferably spaced apart and vertically tiered with the conductive sector cable clamping units adapted to receive a series of vertical sector cables.
[0012] Preferably, the number of phase switches can be three and the system can be adapted to switch three lots of three phase sector cables with the conductive sector cable clamping units of each phase switch being in arranged in a first line and the conductive sector cable clamping units of adjacent phase switches being arranged in a second line substantially perpendicular to the first line so that sector cables from each three phase sector cables are preferably attached to sector cable clamping units substantially in a series of spaced apart lines.
[0013] In some embodiments, the conductive block portions are preferably interconnected to corresponding conductive sector cable clamping units through slots formed in an insulating panel. The conductive block portions are preferably interconnected to corresponding conductive sector cable clamping units by means of a threaded screw engaging a threaded aperture.
[0014] The activation switches are preferably inserted substantially horizontally and the sector cables are preferably inserted substantially vertically. The system can also include a neutral bar interconnecting a series of conductive sector cable clamping units for interconnecting the neutral cables of three phase sector cables. The series of conductive block portions can include a series of tabs for engagement with an activation switch in the form of a conductive plate so as to thereby form an interconnection between conductive block portions.
[0015] The conductive sector cable clamping units can include a conductive block having an arcuate cross section having slotted walls and a dovetailed plate having a series of threaded apertures for insertion into the slotted walls, and at least one threaded screw bolts engaging with the dovetail portion for firmly affixing an inserted sector cable to the conductive sector cable clamping unit.
[0015A] In accordance with a further aspect of the present invention, there is provided a low voltage, high current switching system including: a series of phase switches, with each phase switch switching three sector cables between a series of distribution cables; each phase switch further including: a series of conductive block portions having profiled surfaces which, in conjunction with adjacent conductive block portions form a cavity for the insertion of an activation switch, with said activation switch having a surface for conductively interconnecting adjacent conductive block portions within a cavity; at least one of said conductive block portions including a distribution unit for conductively interconnecting a series of distribution cables for distribution of electrical services from the system; a series of conductive sector cable clamping units each conductively interconnected to at least one corresponding conductive block portion, said sector cable clamping units including clamping means for conductively clamping a sector cable; and a neutral bar interconnecting a series of conductive sector cable clamping units for interconnecting the neutral cables of three phase sector cables; wherein the insertion of the activation switches into said cavities acts to switch power from predetermined ones of said conductive sector cable clamping units to said distribution unit.

[0027] Fig. 11 to Fig. 14 are schematic illustrations of the switching of a single phase of an embodiment.
[0028] The preferred embodiment provides a three way link switch which is able to substantially seamlessly switch a distribution load between three sources. This switching capability will be reviewed further hereinafter.
[0029] Turning initially to Fig. 1, there is illustrated a three phase three way switching system1 constructed in accordance with a first embodiment. This system is design to switch, for each of three phases, a series of distributions, between three input sources.
[0030] The arrangement 1 is highly modular, whilst still being compact. Each phase is switched by an identical phase switch unit 2-4. An associated neutral connection 5 is also provided for providing neutral facilities. The phase switch units 2-5 are mounted on stepped panel with insulating phase separator walls 10 and supported by brackets 8, 9 during assembly, which is attached to a base 11. The unit 1 further includes clear insulating covers (not shown) which covers the main phase contact units 2-5. The four core sector cables including neutral sector cables e.g. 7 are vertically inserted from the floor of the unit 1 in the usual manner. Each of the switch unit includes plastic covers e.g. 6 and clear service terminal covers 12, so that the switch unit is fully touch safe.
[0031] Turning now to Fig. 2, there is illustrated a front side perspective view partly exploded of the switching system 1. In this arrangement, the top phase switch unit 2 is shown partly exploded, as is the bottom neutral unit 5.
[0032] The insulating cover 6 (having caps 15-17) is removed revealing a series of simple conductive portions. Each cap e.g. 15 is placed over an aperture 32 through which a detachable link device or switch 18 is inserted. The link device 18, as will be illustrated in more detail later, interconnects conductive blocks 19, 20. Link devices 21 also perform similar functions.
[0033] The link devices 18 & 21 can be equivalent to those shown in detail in PCT application PCT/AU98/00537 entitled "A Link Switch" which illustrates a detachable link switch which includes two plates which are forced apart to provide a conductive interconnect with mating surfaces. The link device 18 is activated by means of a handle which is twisted to activate the link device. Upon insertion, the link device provides a conductive interconnection between the conductive blocks 19, 20. Similarly, the link devices 21 provide a conductive interconnect between corresponding conductive blocks. In this manner, the switching is provided by the insertion and activation of corresponding link devices.
[0034] The bottom neutral bar assembly 5 includes a clear insulating cover 25 which covers three substantially equivalent neutral interconnections 26, 27 28. The neutral connection 28 is shown partially exploded, with a front slotted clamp base portion 31, slotted dovetail top 30 and two screw bolts 29 cooperating to clamp a neutral cable. This neutral bar assembly will be reviewed further in Fig. 8.
[0035] Turning to Fig. 3, there is illustrated the back side of the switching system 1, again showing the three symmetrical phase switching units 2-4 with the top switching unit shown in an exploded view. The back of the switching unit includes three substantially identical sector cable clamps 40, 41, 42, with the clamp 40 being shown in an exploded view. The sector cable clamps act to clamp a corresponding phase sector cable. Further, each sector cable e.g. 42 includes a cable reception element 43, dove tail unit 44 and one or more screw bolts 45 for clamping the sector cable to the reception element 43. A clear insulating cover 46 is provided to insulate the assembled unit on each level.
[0036] Turning to Fig 4, there is illustrated a further cut away exploded view of portions of the switching unit with the top phase switching unit shown in an exploded form. Like numerals indicate like features. Whilst the arrangement of Fig. 4 is similar to Fig. 2, it is noted that both link units are extracted 18, 21. Further illustrated in Fig. 4 is the conductive interconnect structures, including top mirror symmetric terminal block contacts 19, 20 and bottom symmetric link contact structures 57, 59, and central link contact structure 58. The two link units 18, 21 can be interchanged within above three contact areas depending on demand.
[0037] These structures engage with cable reception elements, for example 43, through slots 61, 62, formed in the insulating wall of the panel 10. The conductive end plugs 63, 64 of the reception element 43 abut the corresponding conductive interconnect structure e.g. 20 through the slots 61, 62. This is illustrated in more detail, initially in Fig. 5, which illustrates the operable portions of the conductive interconnect structure 20 which connects with the cable reception element 43 and is bolted firmly thereto by means of threaded screw 67. Also shown in Fig. 5 is a series of distribution slots 70 for the insertion of distribution cables for localised distribution of electricity. The distribution cables can be affixed by means of clamping screws 69 in the usual manner.
[0038] Whilst Fig. 5 illustrates the operable portions interconnecting the conductive interconnection structure 20, Fig. 6 illustrates the operable conductive portions for interconnecting the bottom conductive interconnection structure 59, again including the cable reception element 43 which is attached by means of screw bolt 66.
[0039] Fig. 7 illustrates the operable conductive portions for interconnecting the bottom center conductive interconnection structure 58, which is attached to a corresponding cable reception element 43 by means of bolt 75.
[0040] Overall, it will be understood that conductive interconnect structure 19 is mirror symmetric with structure 20 and conductive interconnect structure 57 is mirror symmetric with element 59 and so their corresponding interconnects are not described.
[0041] Fig. 8 illustrates a partially exploded view of the neutral bar assembly 5. The neutral bar 76 interconnects with tree slotted neutral cable reception element e.g. 31 and is bolted firmly thereto by means of threaded screws 78. The dovetail top 30 can equally be slotted from the top section or pushed from the lower bottom side into the neutral cable reception element and one or more screw bolts 29 for clamping the neutral sector cable to the neutral reception element. The neutral bar 75 has a series of distribution slots 77 for the insertion of neutral distribution cables for localised distribution of electricity. The neutral distribution cables can be affixed by means of clamping screws 69 in the usual manner.
[0042] By way of further illustration, Fig. 9 illustrates the attachment of the support bracket 9 to the base 11 with the turret top hardware. Fig. 10 illustrates a back view of the assembled unit illustrating a series of sector cables 81 - 83 to their cable reception elements.
[0043] Advantageously, the sector cables are grouped together into color or phases, with the three first phase (red) sector cable from each four core sector cable going to a first switch 2, three second phase (white) sector cables going to a second switch 3, three third phase (blue) sector cables going to a third switch 4. The neutral cables (black) going to the neutral interconnect. This allows for the main 4 core sector cables to be laid out in a very simple manner, side by side, and minimizes the need for cable movements after initial set up.
Switching
[0044] Denoting each of the link switches Al (18), A2 (50) and A3 (51) then the arrangement 1 allows for simplified switching. Switching for a single phase will now be discussed.
[0045] In Fig. 11, there is shown the normal arrangement where mains cable 1 and mains cable 2 are feeders from individual pad mounts and main cable 3 is a branch feeder. In some cases the branch feeder is used to boost capacity by incorporating an additional pad mount. However, in this situation each switch Al, A2 and A3 is extracted thereby providing an open point from all feeders. Each of the services are thereby powered from their own feeders.
[0046] Next, as illustrated in Fig. 12, the link Al can be inserted to bypass mains cable 3. In this case, an open point may be required further down a chain of pillars to isolate transformers where required.
[0047] As shown in Fig. 13, in some situations the link A2 or A3 can be inserted and the link Al extracted to provide an open point on one side and to activate mains cable 3. The loads can be alternated by alternating the insertion of A2 or A3. Fig. 14 illustrates the case where link A3 is inserted. Normally, only one link per phase is required, however, link A2 or A3 can be used in conjunction with link Al where further power is required. The choice of link of A2 or A3 can be determined by load balance. In such cases, the service cables are activated and can only be isolated through switching further down the line.
[0048] The three link switches per phase allow for individualised source control for each set of service cables.
[0049] Further, the embodiments allow for simple, rapid flexible control over the insertion of link switch elements for the control of power to each set of service and allowing for the individual isolation of transformers. For example, simple straight through connections are easily made in the present embodiments. The overall arrangement is compact and easy to install with minimal cable twisting as the sector cables only need to be lined up in parallel. This reduces the ability to mix up cables and to wire the system up wrongly.
[0050] The use of stranded sector cables is enhanced due to the sector cable clamping units.
[0051] The embodiments allow for connection through to feeders at all times whilst external transformers are being used. It can be seen that the embodiments provide for simplified switching with the three detachable link switches providing the capability to independently switch the inputs and the outputs in combination and with extreme flexibility. This is to be contrasted with prior art three way switches, such as that disclosed in Australian Patent 2013222000 which do not provide for simplified switching.
[0052] Further, in the present arrangement, power can be switched via switches Al between the mains cables 1 and 2 without going through the third link A3. As such, the mains cables 1 and 2 can be placed in series without reference to mains cable 3. This is to be contrasted with the prior art devices which do not allow for the same level of independent switching between inputs and outputs.
[0053] Further, the whole system can be provided in a preassembled form, the cables set up on site in rows and the touch safe panel inserted over the sector cables and the system bolted together.
Interpretation
[0054] Reference throughout this specification to "one embodiment", "some embodiments" or "an embodiment" means that a particular feature, structure or characteristic described in connection with the embodiment is included in at least one embodiment of the present invention. Thus, appearances of the phrases "in one embodiment", "in some embodiments" or "in an embodiment" in various places throughout this specification are not necessarily all referring to the same embodiment, but may. Furthermore, the particular features, structures or characteristics may be combined in any suitable manner, as would be apparent to one of ordinary skill in the art from this disclosure, in one or more embodiments.
[0055] As used herein, unless otherwise specified the use of the ordinal adjectives "first", "second", "third", etc., to describe a common object, merely indicate that different instances of like objects are being referred to, and are not intended to imply that the objects so described must be in a given sequence, either temporally, spatially, in ranking, or in any other manner.
[0056] In the claims below and the description herein, any one of the terms comprising, comprised of or which comprises is an open term that means including at least the elements/features that follow, but not excluding others. Thus, the term comprising, when used in the claims, should not be interpreted as being limitative to the means or elements or steps listed thereafter. For example, the scope of the expression a device comprising A and B should not be limited to devices consisting only of elements A and B. Any one of the terms including or which includes or that includes as used herein is also an open term that also means including at least the elements/features that follow the term, but not excluding others. Thus, including is synonymous with and means comprising.
[0057] As used herein, the term "exemplary" is used in the sense of providing examples, as opposed to indicating quality. That is, an "exemplary embodiment" is an embodiment provided as an example, as opposed to necessarily being an embodiment of exemplary quality.
[0058] It should be appreciated that in the above description of exemplary embodiments of the invention, various features of the invention are sometimes grouped together in a single embodiment, FIG., or description thereof for the purpose of streamlining the disclosure and aiding in the understanding of one or more of the various inventive aspects. This method of disclosure, however, is not to be interpreted as reflecting an intention that the claimed invention requires more features than are expressly recited in each claim. Rather, as the following claims reflect, inventive aspects lie in less than all features of a single foregoing disclosed embodiment. Thus, the claims following the Detailed Description are hereby expressly incorporated into this Detailed Description, with each claim standing on its own as a separate embodiment of this invention.
[0059] Furthermore, while some embodiments described herein include some but not other features included in other embodiments, combinations of features of different embodiments are meant to be within the scope of the invention, and form different embodiments, as would be understood by those skilled in the art. For example, in the following claims, any of the claimed embodiments can be used in any combination.
[0060] In the description provided herein, numerous specific details are set forth. However, it is understood that embodiments of the invention may be practiced without these specific details. In other instances, well-known methods, structures and techniques have not been shown in detail in order not to obscure an understanding of this description.
[0061] Similarly, it is to be noticed that the term coupled, when used in the claims, should not be interpreted as being limited to direct connections only. The terms "coupled" and "connected," along with their derivatives, may be used. It should be understood that these terms are not intended as synonyms for each other. Thus, the scope of the expression a device A coupled to a device B should not be limited to devices or systems wherein an output of device A is directly connected to an input of device B. It means that there exists a path between an output of A and an input of B which may be a path including other devices or means. "Coupled" may mean that two or more elements are either in direct physical or electrical contact, or that two or more elements are not in direct contact with each other but yet still co-operate or interact with each other.
[0062] Thus, while there has been described what are believed to be the preferred embodiments of the invention, those skilled in the art will recognize that other and further modifications may be made thereto without departing from the spirit of the invention, and it is intended to claim all such changes and modifications as falling within the scope of the invention. For example, any formulas given above are merely representative of procedures that may be used. Functionality may be added or deleted from the block diagrams and operations may be interchanged among functional blocks. Steps may be added or deleted to methods described within the scope of the present invention.
