[0058] Figure 10 and 11 illustrates another realization of bus 505.In this was realized, single two path connectors 1030 comprised the threaded stud 1040 and 1050 that is connected respectively to three tunnel " Y " connector 1010 and 1020, and described three tunnel " Y " connector 1010 and 1020 is similar to the connector 710 of Fig. 7.A kind of so exemplary two path connectors 1030 are 600 amperes of attachment plugs of being made by CooperPower Systems.Description to this attachment plug is provided in " the molded rubber product 600-46 " of Cooper Power Systems, and its disclosure is merged in by reference.
[0059] in this was realized, three independent parts were assembled together and form bus 505.Two in the parts of bus 505 is three tunnel " Y " connector 1010 and 1020.The probe 1014 and 1016 that three path connectors 1010 are admitted threaded stud 1012 and are screwed to threaded stud 1012.Similarly, three path connectors 1020 probe 1024 and 1026 admitting threaded studs 1022 and be screwed to threaded stud 1022.
[0060] the 3rd of bus 505 the is two path connectors 1030, and it comprises two groups of internal threads, wherein has one group of internal thread on the every end of conducting rod.One group of screw thread shown in Figure 11.These receive threaded threaded studs 1040 and 1050, described threaded stud 1040 and 1050 comprises a 1040a and 1050a respectively.Threaded stud 1012 and 1022 passes a 1040a and 1050a respectively.Probe 1014,1016,1024 and 1026 is fastened on threaded stud 1012 and 1022, so that engage threaded studs 1040 and 1050, and finish electrical connection thus.The replaceable realization that should be noted that the bus 505 shown in Figure 10 comprises and removes any probe 1014,1016,1024 and 1026, and uses the electric-conductor with internal thread to be building up to the mechanical connection of various effective switch element (not shown).
[0061] Figure 12 illustrates another realization of bus 505.Bus 505 comprises three parts 1010,1020 and 1290. Parts 1010 and 1020 were described about Figure 10.Should be noted that the probe 1014,1016,1024 shown in Figure 10 and 1026 and threaded stud 1012 and 1022 be included in the bus 505 of Figure 12, but not shown in Figure 12.Threaded stud 1040 and 1050 is surrounded by corona shielding 1205a and 1205b respectively, and described corona shielding 1205a and 1205b are insulated material 1210a and 1210b again respectively and surround.Insulating material 1210a and 1210b are surrounded by semiconductive shell 1215a and 1215b respectively.In general, these elements can be made by identical materials, and carry out identical function as previously described.
[0062] exemplary two path connectors 1290 shown in Figure 12 comprise two matrix finger- like contact 1240a and 1240b that are screwed in the conductive base 1270.The variant of this element can only comprise a finger-like contact (1240a and 1240b) and long conductive base.These matrix finger-like contacts are coupled to probe 1245a and 1245b, and described probe 1245a and 1245b are screwed to threaded stud 1040 and 1050 respectively.Corona shielding 1260 and 1250 surrounds finger- like contact 1240a and 1240b and probe 1245a and 1245b respectively.Corona shielding 1260 and 1250 is insulated material 1255 and semiconductive shell 1280 surrounds.Corona shielding 1260 and 1250, insulating material 1255 and shell 1280 can be made by the material of carrying before, and can work like that as previously described.Bus 505 shown in Figure 12 is by assembling among matrix finger-like contact 1240a that respectively the probe 1245a and the 1245b of connector 1010 and 1020 is pushed two path connectors 1290 and the 1240b.
[00631 Figure 13 illustrates another exemplary bus bar system.Provide description in conjunction with the description of Fig. 5 to bus 510 and 515 before.Bus 1300 is configured to by 1305,1310,1315 and 1320 and two cables 1325 and 1330 of three path connectors of four standards.Three path connectors 1305 and 1310 are coupled to cable 1325, and three path connectors 1315 and 1320 are coupled to cable 1330.Those that describe before connection between the structure of three path connectors and three path connectors and the cable is similar to.Three path connectors 1310 are coupled to three path connectors 1315 by two path connectors 1030, threaded stud or the interface unit (not shown) that is equal to.The Bol-T connector (classification number 600-30 and 600-50) that three path connectors 1305,1310,1315 and 1320 can use Cooper PowerSystems to make realizes that the specification of this connector is merged in by reference.
[0064] can carry out several observations about the various realizations of bus-bar system.For example, bus-bar system is modular, can be made by standard parts and components again.This means that people can assemble bus by simply cable being cut into suitable length and these cables being connected to three path connectors.These are different with conventional bus-bar system, and described conventional bus-bar system comprises the big copper or the bar of other metals, and the bar of described copper or other metals must be formed or bend to given shape.The modularization that this bus-bar system provides allows to make easily the various configurations of switching device.In addition, some parts that are used to make up bus-bar system are standard parts and components.More specifically, threaded stud, probe and matrix finger-like contact are used to (promptly be used for cable is connected in the connector of the lining on the switching device) in other connectors.This means that bus-bar system can use standard parts and components assembling.In addition, this means that manufacturer can keep the less stock of the parts type and the total quantity that are used to make bus and switching device, because the modularization of parts allows bigger interchangeability.In addition, use modularization and interchangeable parts, the connector that is used for fuse and switch element of same type for example means easier and replaces the parts of another kind of type more quickly with a kind of parts, for example replaces switch with fuse.
[0065] this interchangeability makes that retail trader and manufacturer are easier to switching device is carried out minor modifications, to satisfy particular demands.This interchangeability also means, if switch element fault or need safeguard with the redaction of the switch element installed before or the switch element of another kind of type, people are easier and more quickly the switching device in the work is safeguarded to replace described effective switch element.In addition, by being used in a lot of connector standardsization of switchgear components, manufacturer, retail trader or attendant can obtain complete switching device and remove the switch element that is connected to one of bus, substitute this switch element with another the multi-link device (for example three road Bussing connectors) that is attached to bus, and add extra switch block, rather than must be from zero initialize switch device fabrication to bus and switching device.Same process can be finished to come for several times and add more a plurality of in fact switch elements according to expectation or requirement.In addition, if receive and at hand the unmatched specification of switching device, can decompose switching device by switch element is disconnected from the supporting construction of bus and switching device inside.In addition, if necessary, can be suitable for the span that satisfies described specification and be orientated and decompose bus by connector is disconnected and reconfigures bus and switching device from cable, and need not to make another switching device with diverse one group of parts, cut the waste thus and improve flexibility about the specification of each switching device.These changes can be on the spot, in the merchandising location (for example retail trader) or in manufacturing site location, carry out.
[0066] in addition, exemplary switchgear can be configured to and can repair with upgradeable.Consistent interface, size and modularization makes that being standardized into is possible in several parts (for example bus, fuse, switch and circuit breaker), and has nothing to do with specific standard or each the use.Parts are interchangeable, replaceable and upgradeable, are providing flexibility aspect design, modification, the maintenance and operation.The standardization of parts and modularization make equipment reparation, replacement or upgrading simpler, quicker and so expensive, and reduce the stock's requirement to manufacturer, retail trader and manufacturing or replacement parts owner.In addition, striding a plurality of electric pressures makes switch, fuse, circuit breaker and bus part standard increase the design of switching device and the flexibility in the operation.This consistency reduces installation cost, and has also reduced inventory cost when making up with short delivery date (lead time).
[0067] as embodiment, switching device can be established and cooperate new specification or replace existing switching device as repacking.In general, existing switching device is design early, has specific dimensions (for example height, width and the degree of depth) and in (promptly apart from) and lining orientation (i.e. horizontal linear as illustrated in fig. 1 and 2) each other at interval between the lining on the way on the switching device and position and the switching device header board, all these provide at least a portion of so-called switching device specification.Make new switching device and be coupled to new space (creating specification in this case again), perhaps replace existing switching device (in this case by existing switching device being measured or determined by the tables of data reading of data that is associated from existing switching device the specification of existing switching device).In either case, manufacturer receives specification and begins to set up the first required pack module of bus-bar system first bus by collection and comes the assembled switch device, and described bus-bar system is used to carry a phase of electric energy.
[0068] as embodiment, if first bus is the bus 1300 of Figure 13, manufacturer will collect four connectors (1305,1310,1315 and 1320) and have two cables 1325 and 1330 of suitable length based on the specification that received, as first pack module, and, thereby form bus 1300 with these module couplings.Effectively switch element is coupled to bus subsequently.Effectively the type of switch element (for example fuse or switch) is to be determined by the specification that is received.Effectively switch element is installed on the framework subsequently, thereby the part of each effective switch element (for example lining) is outstanding towards the operate outside space of new switching device like that as previously described.After all buses that need have been mounted, surround bus-bar system and effectively in the inner space that shell limited of switch element surplus air in bus-bar system with effectively around the switch element, this with can use oil or SF 6Further make bus with each other, effectively other parts of switching device of switch element and casing insulation are opposite.Shield semiconductors on the bus and effective switch element are coupled to the point on the switching device subsequently, and described point is coupled to ground when switching device is installed afterwards, thereby makes that the complete front of switching device is not charged.Should be noted that these steps can carry out with interchangeable order, depend on the specification of switching device and the ability of manufacturer.
[0069] similarly, if new switching device needs second bus, then required module is collected by manufacturer, and they are assembled into second bus.For example, if second bus need admit point (being coupled to the point of effective switch element on the bus) than on first bus every farther, two connectors and longer cable are collected in second pack module by manufacturer.These modules are assembled to form second bus subsequently, just as the bus among Fig. 5 505,510 or 515, and are coupled to framework.If the specification requirement triple bus-bar, then manufacturer collects desired module and they is assembled into triple bus-bar and is coupled to framework.Should also be noted that and can use any bus shown in Fig. 5 and the 7-12, rather than the bus 1300 shown in described before Figure 13, other bus-bar systems set up.Should also be noted that and to make interchangeable switching device, thereby the switchgear housing volume inside is filled by the outer insulator (for example EPDM) of deacration.
[0070] should be noted that the lining orientation in new switching device outside does not need to be limited to the horizontal line shown in Fig. 1 and 2.For example, new switching device can make lining be oriented to vertical line, oblique line or many lines, can be coplane or non-coplanar, and even can make lining on the different outer surface of switching device.As embodiment, new switching device can make some linings install on as illustrated in fig. 1 and 2 the header board, and some other lining is installed on the end face of switching device (this surface is not shown in Fig. 1 and 2).
[0071] modularization of bus-bar system allows the various configurations of switching device.For example, the lining on the switching device does not need as shown in figs. 1 and 2 like that on a line.This modularization allows bus and therefore allows switching device to be made like this, and promptly lining can be along arbitrary orientation Anywhere in two header boards of switching device or the framework.Except lining various orientations each other, the interval between the lining can change similarly.The modularization permission lining of bus-bar system is put closelyer or is farther, depends on client's needs.Similarly, the quantity of the lining lining quantity that can be not limited to describe among Fig. 1 and 2.That is, bus-bar system can easily be fabricated to and be held any amount of lining on the suitable switching device.Similarly, bus-bar system and associated switch arrangement can be created and support Dan Yuan and single tap system.Other configurations can be supported three or more sources and tap system.
[0072] same, bus 505 can use parts at hand to assemble in many ways.For example, three path connectors among Fig. 7 are equal to three path connectors 1010 among Figure 10.Therefore, maintenance or the operating personnel that replacing bus 505 can use parts at hand to come the bus 1300 shown in the bus 505 shown in construction drawing 7 or 10 or Figure 13.Equally, by using probe and finger-like contact, bus 505 is that promotion is attachable.This means that assembling, maintenance or operating personnel do not need to use wrench that effective switch element is disconnected from bus-bar system.
[0073] in addition, the bus-bar system of Fig. 5-13 provides the additional safety that exceeds conventional bus-bar system.Comprise that the realization of semi-conductive shell of being coupled to ground prevents that the zone around the bus-bar system from collecting spuious electric charge, described spuious electric charge may damage the people that parts or injury may contact with switching device essence.In such realization, the structure of switching device can be modified.That is, in the not charged switching device in the front of routine, switching device comprises the container of being made by external conductive casing.Header board forms the part of this container.Yet, being coupled in the realization on ground at the semi-conductive shell of bus-bar system parts, outer container needs not be the part of switching device and does not need and is coupled to ground.Bus and effective switch element system itself are positive uncharged, thereby switching device does not need to be coupled to the outer container on ground.In such realization, positive uncharged bus-bar system can be surrounded by solid insulator, protecting it and to avoid polluting, and does not use the canister of ordinary tap device.Therefore, by making the front of bus-bar system own not charged, can develop such switching device, in described switching device, the outer container of switching device or outer surface do not need to be coupled to ground, and switching device still is positive uncharged.
[0074] bus-bar system shown in Fig. 5-13 can be implemented in the switching device of any kind, for example uses SF 6Or in air those switching devices as insulation.In some implementations, the bus-bar system of Fig. 5-13 is implemented in the switching device that comprises solid insulator.One type solid insulator is Ethylene Propylene Terpolymer (EPDM) rubber.This solid insulator has than oil, air or SF 6Higher dielectric strength constant, the solid insulator that this means certain amount is than oil, SF with amount 6Or air provides between bus insulation more.Have the material of dielectric constant greatly by use, each bar bus 505 or 1300 and 510 and 515 can closely be set together, thereby can reduce the overall dimension of switching device.
[0075] switching device that comprises the solid insulation volume property provides the several advantages that is better than the ordinary tap device.At first, the switching device made from solid insulator can be made less than the ordinary tap device, and this allows switching device to be mounted in so unshowy mode.Should note, use the switching device of solid insulator not need to be done forr a short time, but can be manufactured to the size identical with the ordinary tap device, to allow on same installation surface, to replace older switching device and nonessentially for example pour into new concrete slab, perhaps more specifically, alignment or lengthening (by splicing) or replacement underground cables make them be connected to lining position new on the new switching device again.
[0076] combination of the insulation attribute of bus 505,1300,510 and 515 modularization and solid insulator allows non-costliness and makes up the new switching device of size less than the ordinary tap device apace.
[0077] Figure 14 is that an exemplary is used for repairing the logical flow chart of the illustrative methods 1400 of the switching device switch element with modular member to diagram according to the present invention.Referring now to Figure 14, illustrative methods 1400 begins in the beginning step, and advances to step 1405, in step 1405, and the switching device that is provided for repairing.In an exemplary, switching device is at its manipulation fields point, and in use current.In step 1410, the attendant determines whether effective switch element that any needs are repaired, substitute or revise.In an exemplary, effectively switch element comprises fuse, switch and circuit breaker.In step 1412, cable unloads from effective switch element first end that will be repaired, replace or revise.The switch element that is replaced supporting construction from switching device in step 1415 unloads.In an exemplary, supporting construction can comprise the framework of switching device, the protecting sheathing of switching device or the structure of switching device inside.
[0078] in step 1420, the switch element that need be replaced unloads from bus.In step 1425, this switch element is by being coupled to bus with new switch element and supporting construction is replaced.In an exemplary, new switch element is coupled to the connector of bus.In another exemplary, the type of switch element also can change.For example, can remove fuse and can put back to switch in the position that fuse before occupies.In step 1430, cable is attached to switch element again.This illustrative methods proceeds to end step subsequently.
[0079] Figure 15 is the logical flow chart of the tissue of the diagram switching device parts that exemplary is used for revising having modular member according to the present invention or the illustrative methods 1500 of arranging.Referring now to Figure 15, illustrative methods 1500 begins in the beginning step, and advances to step 1505, in step 1505, provides the switching device in the operation, and described switching device has at least one bus and a plurality of switch element that is attached to a connector part.In an exemplary, this bus can comprise that cable is connected with a plurality of, perhaps can comprise integral bus bar (solid busbar).In step 1507, remove cable from first end of switch element and connect.In step 1510, the switch element further supporting construction from switching device unloads.
[0080] in step 1515, one of one of switch element connector from the bus unloads.In step 1520, the configuration of switching device is modified so that extra tie point to be provided.In an exemplary, first and second connectors are three path connectors; Yet, in the scope of this exemplary, can use the connector of other types with two or more tie points.In an exemplary, connector is usually by another connector replacement of many one tunnel at least.In step 1525, switch element or extra connector are coupled to the open circuit tie point of second connector.In step 1530, extra switch element is coupled to the supporting construction of switching device.In step 1535, make up cable and the effectively connection between the switch element other end.This illustrative methods proceeds to end step subsequently.
[0081] Figure 16 is that exemplary is used to make the logical flow chart of the illustrative methods 1500 of the switching device with modular member to diagram according to the present invention.Referring now to Figure 16, illustrative methods 1600 begins in the beginning step, and advances to step 1605, in step 1605, provides first supporting leg of the bus with a plurality of tie points.In step 1610, provide second supporting leg of bus with a plurality of tie points.In step 1615, by first supporting leg is coupled to second supporting leg with one of tie point of each supporting leg is coupled to each other together.
[0082], provides standardized connection at each Coupling point for each tie point, to reduce the stock of connection type in step 1620.Stock's minimizing can occur in manufacturer place, sell a point or take place at the final owner of switching device.In an exemplary, this connection type can comprise promotion connection, probe and matrix contact-connection assembly for electric, and mechanical type connects, and has threaded stud and the electric-conductor that internal thread is connected, in addition other known connection types of those of ordinary skills.In step 1625, at least one effective switch element is coupled to one of all the other tie points on first or second supporting leg, and comprises the coupling that is connected and composed by described standardization.This method proceeds to end step.
[0083] Figure 17 is that exemplary is used for reconfiguring the tissue of the switching device parts with modular member or the logical flow chart of the illustrative methods 1700 of arranging to diagram according to the present invention.Referring now to Figure 17, illustrative methods 1700 begins in the beginning step, and advances to step 1705, in step 1705, complete switching device is provided, and described switching device has at least one bus and a plurality of switch element that is attached to connector part that is made of connector and cable.In step 1710, receive the specification that maybe needs the switching device replaced at new switching device.In step 1715, be the quantity that described complete switching device is revised switch element based on described specification requirement.In an exemplary, can increase or reduce the quantity of switch element as required.
[0084] in step 1720, one or more in the bus can be its part by partially or completely decomposing (break down).In an exemplary, the part of bus can comprise cable and connector.In step 1725, the bus that is decomposed is modified so that comprise much more at least one the road or few one the tunnel.In step 1730, switch element is coupled to the supporting construction of the bus and the switching device of modification as required, described switch element can comprise than the switch element in the original switch device still less or the more switches element and with the original switch device in different switch element types.This process proceeds to end step.
[0085] can also carry out interchangeable realization to the realization of describing before.For example, be replaced in and use promotion to connect (for example probe and matrix finger-like contact), can use mechanical type to connect to the connection of each bar bus and make up.Although this variant makes that the replacement of switching device parts is much more difficult, because skilled worker or assembling person must screw on and back out the replacement parts from bus, but this interchangeable bus-bar system is still used and is allowed fast and the modular parts of assembling each bus easily.
[0086] another replaceable scheme comprises the relative position of putting upside down probe and matrix finger-like contact.Promptly, be replaced in the lining that will comprise matrix finger-like contact and be installed on effective switch element and probe be installed in the connector of bus, interchangeable realization is installed to probe on effective switch element and with matrix finger-like contact and is installed on the connector of bus.
[0087] although probe, threaded stud and matrix finger-like contact are generally made the also known conductive component that can use other metals, alloy or compound to form bus-bar system by copper or copper alloy.In addition, although matrix finger-like contact and probe generally be shaped as cylinder, other geometries are possible.Be also to be understood that probe described herein, matrix finger-like contact and threaded stud can have various sizes, described size can follow or not follow industry, voluntarily, the standard of international or other acceptance.Bus-bar system described herein also allows the flexibility when being one or more planar orientation of lining.That is, the switching device shown in Fig. 1 and 2 is in switching device 100 its lining (be connected device 114a-114b cover with 214a-214f) to shelve in the parallel plane of the base at place.Bus-bar system shown in Fig. 5 and 13 and nonessential bus with coplane and level.
[0088] also have, the bus of each bus-bar system of Fig. 5-13 does not need corona shielding, insulator and shell.In these are realized, only use conducting element to assemble each bar bus.Bus is packaged into air, oil or the SF of switching device inside subsequently 6In the insulator.
[0089] although above-described realization connects at 4 the tunnel, should be appreciated that other realizations are possible.For example, threaded stud 770 can have the second group of screw thread that is attached to the eye and extends to the figure right side.This extension of screw thread will be accepted matrix finger-like contact, make up six road buses to accept the 3rd supporting leg subsequently.Similarly, bus 505 can accept to be equal to the 3rd supporting leg of supporting leg 760, and this supporting leg 760 is coupled to probe 765 to create 5 road buses.This 5 road bus is realized emphasizing the modularization of system and the interconnecting property of standard parts and components, is had the bus of virtually any size with design, and emphasize to connect the flexibility of planar orientation aspect.
[0090] other of bus itself realize for parts described herein and technology it also being possible.For example, the connector of other types (for example two-way connection) also is possible.Referring again to Fig. 7, by eliminating threaded stud 720, probe 730, and corona shielding 740, insulator 745 and protective sleeve 750 be associated outstandingly, can revise supporting leg 710 and make up two path connectors.Threaded stud 725 is fixed on supporting leg 710 inside.A kind of mode that threaded stud 725 is fixed to supporting leg 710 is to make insulator center on the core of threaded stud 725, thereby forms the frictional fit with all the other elements of the supporting leg 710 of this modification.In case be fixed, probe 715a and 715b are screwed to threaded stud 725.This two path connector can be by being coupled to probe 715a with two effective switch elements and 715b is used as bus.Should also be noted that this two path connector can use two mechanical types to connect or matrix finger-like contact substitutes the probe of describing before.In addition, two path connectors can have mechanical type and connect and be connected with a promotion.Should also be noted that two path connectors 1030 of Figure 10 and two path connectors 1290 of Figure 12 can also be implemented as bus under the situation that does not have three path connectors 1010 and 1020.Should be noted that these buses that only use two path connectors can use two mechanical types connect, two promote to connect or a kind of one realize.
