Describe in detail

General structure and technology and embodiment more specifically have been described here, and described embodiment can be used to implement to carry out the more generally distinct methods of purpose.

Fig. 1 illustrates the entire block diagram of an embodiment, and described embodiment distributes to the lamp of location at a distance with power and control signal, such as 99.Each described lamp 99 is connected to receive power and the control signal from breakout box (breakout box).Distribute frame 100 be one by a large amount of breaker modules 102 frames that constitute for example, specific output of each breaker module control.Distribute frame 100 to receive electric energy 55, for example 400 amperes, 3 4/0 feeder cables of electricity mutually that have from being used to distribute.Distribute frame 100 also to receive and be depicted as 140 control signal, in this case, this control signal is the ethernet signal that is sent to Ethernet switch 145.Three-phase electricity and control signal are assigned to each breaker module 102.Each breaker module 102 produces the power and signal output 120 of combination on the specialized configuration cable, described specialized configuration cable comprises power and control conductor.

Output 120 is connected to breakout box 130.The breakout box that a plurality of different structures are arranged.Difference output from different breaker modules is connected to breakout box 135, has the structure that is different from breakout box 130.For example, breakout box 130 is arranged to 208 volts of AC and has 208 volts of delivery outlets 132, also has control connection 134.

Described control can be any form of the one or more luminous elements of control, for example Ethernet, industrial standard DMX (data multiplexer) or other addressable, time slot control line control or other type arbitrarily.Similarly, breakout box 135 comprises 120 volts of AC delivery outlets 136.

Distribute frame 100 high electric current supply 120 to be divided into the power supply of the circuit breaker of a plurality of separation.These supplies are dispensed on the same cable of also carrying out control therein.Yet note, in distributing frame 100, can provide a plurality of voltages simultaneously.Embodiment can be employed different voltages to different breakout boxs.Alternate embodiments can allow different voltages to export the different delivery outlets of identical breakout box to.

If 120 volts of delivery outlets are connected receiving 208 volts of power, yet infringement and safety problem to luminous element may take place.Each breakout box is encoded by line according to its structure.Use the line echoplex technique of " key lines (key wires) " to guarantee that suitable voltage is provided for special-purpose breakout box.Unless and be connected to breaker module up to suitable configuration breakout box, can not provide voltage.

In an embodiment, the loopback that breakout box has on key lines connects, and described key lines is encoded according to its voltage of wanting.This embodiment can have independent line, and described independent line is used as hard-wired key lines.Breakout box comprises loopback, and described loopback requires the compatibility before suitably encouraging breakout box.For example, independent key lines can comprise that 5 possible lines of difference connect, and two in connected these five lines are used for connecting separately arbitrarily.For example, 120 volts of breakout boxs can have the line 2 that is connected to line 5.120 volts of breaker modules can not exported any output voltage to the breakout box delivery outlet, unless up to and line 2 be connected to line 5.Therefore, do not have power output to be supplied to, be connected to breaker module up to the breakout box of suitable configuration.

This has been avoided the voltage of mistake is applied to breakout box.

As additional release mechanism, power is not connected to breakout box, finishes connection fully up to breakout box and all middle connections.Therefore, do not apply power, be connected up to compatible breakout box to cable 120.Therefore, any do not have main line (trunk) connector of terminal never to be activated.The people who handles this connector is safe from danger, even they are in the dangerous environment, for example stands in the water.

Fig. 2 illustrates the electrical connection that distributes between frame 100 and the breakout box 135.Main power mains 100 is input to 3 phase bus-bar systems (bus bar system) 200, is made of bus 210,211,212,213 in distributing frame, as further detailed explanation here.Be to be further appreciated that each relay shown in Fig. 2 can use auxiliary relay, Chuan Lian two relays are used and replace a single relay therein.The use of the auxiliary relay of two series connection has been avoided the needs of power supply or has been made a large amount of power pass relay coil.

Bus-bar system 200 is parallel to each breaker module provides power, comprises as directed breaker module 201.Power from bus is employed through high contactor 220.In this embodiment, can use 75 amperes contactor.Contact 221,222 is connected between bus 200, power line 230 and the trunk cable 120.Use the opening and closing position of contactor coil 223 control contactors.When contactor coil 223 was energized, contact 221 and 222 was connected.In breakout box, power line 230 offers delivery outlet 136 with power.Whole phase places of contactor transfer power.

As described here, contactor is supplied with set of circuits circuit breaker 241.The output of each circuit breaker sends the trunk cable of delivery outlet 136 to.Each independent circuit breaker control is the power of the delivery outlet of group separately.

Be typically expressed as 240 five wire harness and be used to provide 10 kinds of different combinations, allow 10 kinds of different only breakout boxs/breaker module combination.Certainly, any amount of line can be used to this purpose, allows the only structure of any amount.

The excitation 224 that is used for contactor control coil 223 can be connected in series through suitable key lines.Therefore, contactor can only be energized when suitable key lines is connected to each other, and crosses the power of entire path so that contactor coil receives.The interior connection of breakout box inside provides the connection between the key lines.If the coding of the coding of breaker module and breakout box does not match, then the relay coil circuit is incomplete, and then supply power not.

In operation, use power drive on the key lines to be used for the control of contactor.Contactor can be only be energized when two key lines 232,234 are connected in breakout box inside.Breakout box 135 comprises the preparation (provision) of admitting whole five lines, but has only specific a pair of line to be connected at 250 places.In Fig. 2, line 232 is connected to line 234.This had guaranteed that before applying power the voltage of breakout box 135 and further feature are complementary with the breaker module 201 of special use.

Main bus bar 266 also is used to the degree of safety of adding.Main relay 271 has contact 263, and described contact 263 is connected between the coil 223 of power supply 264 and main contactor 220.The contact 263 of main relay 271 must be closed any power to be used to supply with.

Main bus bar power supply 265 provides power to many devices in the frame.Main switch 262 is connected between power supply 265 and the main bus bar 266.In an embodiment, main bus bar 266 is made of the 5th bus of this internal system.The coil 264 that is used for main relay from the main bus bar excitation.When power was provided on the main bus bar, contact 263 was closed, thereby made contactor 220 supply powers when these conditions meet.Yet, also provide, if main switch 262 is opened, it automatically closes the whole power for whole breakout boxs, thereby opens whole relays.Be used for contactor coil 223 and come from low-tension supply 264 with the power that is used for loopback/key lines.Switch 262 is arranged between low-tension supply 264 and the contactor coil 223 by series connection.When switch was opened, the electric current that passes contactor coil was interrupted.Open each contactor, thereby cut off the electric current of all loads that are connected to breakout box.Thereby main switch 262 is emergency switches, and described main switch cuts off all outer power supplys of frame, for example, can be used for emergency and for convenience's sake.This can eliminate necessity that the operator closes whole 72 circuit-breakers on the interrupt module that is configured in the frame.

Illustrated that above low-tension supply is to 272 and 273 relay coil supply power for example.Yet many high power relays need be at the 120V power of relay.The coil that the adaptation of auxiliary relay can allow 264 low-tension supply for example to be connected to auxiliary relay uses the convertible contacts of auxiliary relay to provide 120V power to main coil then.

For example, if breaker module 201 is configured to provide 120 volts of power, specificly then need be used for loopback here to line (being 232 and 234).This guarantees that 120 volts of power only are used for breakout box, and described breakout box disposes 120 volts of delivery outlets.

Interior loopback connects 250 and is maintained at breakout box inside.This internal loopback among this embodiment connects loopback between online 232 boxes 234, is 120 volts of breakout boxs with indication breakout box 135.For example, the connection of the difference between line can be used to different loopback connections.Article five, the not collinear ability that 10 kinds of different loopback combinations are provided, thus be 10 kinds of different possibility structures of breakout box.

Cable 120 through-put powers, ground connection and signal, yet, be established the power that also is not connected to the hot line that comprises power with the excitation contactor before up to loopback.In case loopback is established, contactor 220 is energized, and power is applied to line 230 to provide power to delivery outlet 136.Thitherto, however cable does not have power; Except the power controlling on key lines.

Selectively, although top 120 volts of connections have been described, be understood that this system also can use 208 volts of connecting boxes to use other voltages arbitrarily.For 208 vor signals, operation can be suitable for providing six 15 amperes of delivery outlets, perhaps three 30 amperes of delivery outlets, perhaps its combination arbitrarily.Described system also can use leggy control and be connected.For example, breakout box can be configured to the delivery outlet on the described box and supply with 3 phase power.The applicable different loopback of each only breakout box power configuration connects.Therefore, with respect to the voltage output that provides, this system prevents that out of order breakout box is used.

For further safety, loopback voltage can be Current Control and/or ground fault interruption protection.

Except key lines, also have control cable 260 with 120, described control cable is from distributing frame configuration in 100 fens breakout box 135.This control cable can be used for luminous element with control signal, and described luminous element provides power by delivery outlet.For example, DMX controls, Ethernet is controlled or be used for any other control protocol of device or one or more territories of its combination in this control.In fact, agreement can only be and compatible mutually those of the line of cable inside or signal vehicle.For example, can use any agreement that on twisted-pair feeder, to transmit.

Pin configuration by connector feet realizes on the other hand.Fig. 3 illustrates cable 300 ends and the details drawing of the demonstration cross section of connector feet 302 is shown.Connector 302 comprises a plurality of pin with respect to the differing heights of the basal surface 310 of connector.Each pin is connected to the respective gut in the cable 300.Can be by a plurality of every type pin.Fig. 3 illustrates 2 every type pin, but be understood that can have a plurality of, every type pin between 1 and 15 for example.

Pin 304 is connected to the line 306 of cable inside.Pin 304 expression safety grounds, and line 306 thereby be connected to safety ground.Pin 304 further extends out with respect to the bottom surface 310 of connector.Therefore, when connector mated, pin 304 was at first realized contact, thereby guarantees that safety ground at first is established.For example, this determines to realize that breakout box at first is grounded during connecting.

Secondly, pin 315 is realized contact, and is connected to line 318, and described line 318 expression power supplys connect, AC power for example, for example 120 volts and/or 208 and/or 220 volts.Note,, be not energized less than these lines before the key lines excitation at contactor with top the same.

Pin 325 extends the shortest distance, and is connected to the line as 328, represents holding wire as 328 line.Holding wire comprises key lines recited above, also has for example other signals of Ethernet and DMX.

Each pin of described group is recessed with respect to all the other pin, guarantees the connection fully of one group of pin fully, before next group pin can obtain to connect.For example, amount of recess can be about 1mm, but depends on the size of connector and other parameter, but more general any recessed suitable between 0.3mm and 5mm.

Like this, in operation, safety ground is at first set up, based on realize at first connecting farthest pin 304 is shown.After safety ground was established, the power line was connected on pin 315, but before contactor is energized based on key lines, did not in fact give the breakout box supply power.At last, connect key lines and Ethernet and other control line, these lines power up, provide power to system to contactor.

Another problem of this system is to connect to be untied.This especially is a problem for the high electric current connection of setting up in frame.Therefore, an aspect of this system uses solid metal to keep all connections, connects with metal bolts; From beginning entering part 109, from start to finish to the connection of contactor outside.The bolt connection of this metal to metal can minimize voltage drop and can prevent that line from being drawn pine.The bolt of solid metal connector connects the curling connection of having eliminated the standard line.The curling connection of high Ampereconductors often is difficult to apply suitably, and can fluff in time.This can cause security incident on one's body.The curling heating that is subjected to high current loads of absent-mindedness, and then will be oxidized in time also, thereby worse connection become.

The described still connection that increases between the terminal of conductor and use of curling.Each connection can produce a voltage drop.The use stranded wire and the needs that curl and be connected in any high Ampereconductors part eliminated by this system, because entire portion is connected and composed by the metal to metal bolt.
