Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail, can implements according to this with reference to specification word to make those skilled in the art.
As shown in Figure 1,
Based on a power transfer device of DCS, be applied to circuit, described circuit comprises the first power supply, second source, and wherein, described first power supply is connected with external circuit with any one in second source, comprising:
First switch 1, it is connected with the first power supply 110, controls described first power supply 110 and whether powers;
Second switch 2, it is connected with second source 210, controls described second source 210 and whether powers;
Data acquisition module 3, it is connected with described first switch 1, described second switch 2, and gathers the disconnected of described first switch 1 and close state and the electric current by it, and the disconnected of second switch 2 closes state and the electric current by it;
DCS controller 4, it is connected with described data acquisition module 3, for receiving the data that described data acquisition module 3 gathers, and judges whether described first switch 1 has electric current to pass through, if described first switch 1 no current passes through, then DCS controller 4 sends the instruction of opening second switch 2;
On-off controller 5, it is connected with described DCS controller 4, receives the instruction of the described unlatching second switch 2 that DCS controller 4 sends, and opens described second switch 2.
Usual external circuit is all be connected with power supply, powered by power supply, once power outage, external circuit will be caused to paralyse, cause a series of adverse consequences, such as in desulfurization chemical industry, once desulfurization section power failure, the whole system power-off comprising desulfurization section will be caused, at this time, working power and stand-by power supply can be realized, seamless automatic switchover namely between the first power supply 110 and second source 120, just seem and be even more important, usually, whether Power supply can control by arranging switch, it is disconnect or close that data acquisition module 3 gathers switch, off-state can be set as " 0 ", close as " 1 ", if data acquisition module 3 collects the state of the first switch 1 for " 0 ", namely disconnect, this information is sent to remote controllers, here be DCS controller 4, then the instruction of closed second switch 2 is sent to on-off controller by remote controllers, on-off controller 5 receives this instruction, described second switch 2 will be closed, make second source 210, namely stand-by power supply can normal power supply, when so just can be implemented in working power namely the first power supply 110 disconnection, automatically switch to stand-by power supply, namely second source 210.
Described based in the power transfer device of DCS, described DCS controller 4 also comprises: judge whether described second switch 2 has electric current to pass through, if described second switch 2 no current passes through, then DCS controller 4 sends the instruction of unlatching first switch 1;
Equally, if at stand-by power supply, namely second source 210 cannot normal power supply when, can realize automatically switching to working power, namely the first power supply 110, realizes the seamless switching between two power supplys, guarantee no matter be which kind of situation, can external circuit normal power supply be given.
Described on-off controller also comprises: the instruction receiving unlatching first switch 1 that DCS controller 4 sends, and opens described first switch 1.
Described based in the power transfer device of DCS, also comprise:
First interlocking switch 6, it is connected with data acquisition module 3, described data acquisition module 3 gathers the disconnected of described first interlocking switch 6 and closes state and send to DCS controller 4, wherein, described first interlocking switch 6 is set to: if described second switch 2 no current passes through, and the first interlocking switch 6 closes, then DCS controller 4 sends the instruction of closed first switch 1 to on-off controller 5, it receives described instruction, closed described first switch 1.
Described based in the power transfer device of DCS, also comprise:
Second interlocking switch 7, it is connected with data acquisition module 3, described data acquisition module 3 gathers described second interlocking and opens the disconnected of 7 passes and close state and send to DCS controller 4, wherein, described second interlocking switch 7 is set to: if described first switch 1 no current passes through, and the second interlocking switch closes 7 conjunctions, then DCS controller 4 sends the instruction of closed second switch 2 to on-off controller 5, it receives described instruction, closed described second switch 2.
In reality, we sometimes need to overhaul circuit, at this time just need deenergization, if we are by disconnection first switch 1, disconnect the first power supply 110, at this time data acquisition system is to by the first switch 1 no current, will closed second switch 2 automatically, be switched to second source 210, connect external circuit, at this time will cause damage to person to the staff of maintenance, this is unallowed, so need here to arrange double insurance, here the first interlocking switch 6 and the second interlocking switch 7 is provided with respectively, a Rule of judgment is added to electrical source exchange, described first switch 1 no current is only had to pass through, and the second interlocking switch 7 closes, in two simultaneous situations of condition, just can close described second switch 2, be switched to second source 210, or, described second switch is only had to pass through without 2 electric currents, and the first interlocking switch 6 closes, in two simultaneous situations of condition, just can close described first switch 1, be switched to the first power supply 110, and the first interlocking switch 6 here and the second interlocking switch 7 can be controlled by artificial to hit at DCS system operating table millet cake, further increase the fail safe of electrical source exchange.
Described based in the power transfer device of DCS, described first switch no current passes through, and is specially: described first switch 1 disconnects and is less than 1A by its electric current.
Described based in the power transfer device of DCS, described second switch no current passes through, and is specially: described second switch 2 disconnects and is less than 1A by its electric current.
In order to provide fail safe, switch no current is existed by being set to switch disconnection and being less than 1A two conditions by its electric current simultaneously, and in reality, due to data collecting module collected to by the electric current of switch be exist drift, a smaller mobility scale can be there is, such as 0.05A, 0.08A, even if reality is 0 by the electric current of circuit, data collecting module collected to current data also can be not necessarily 0, can be 0.05A, 0.08A, so electric current is set to be less than 1A, in fact no current can be determined here.
Described based in the power transfer device of DCS, the disconnected state of closing of described first interlocking switch 6, described second interlocking switch is manual operation, manually hits at DCS system operating table millet cake and controls, further increase the fail safe of electrical source exchange.
Although embodiment of the present utility model is open as above, but it is not restricted to listed in specification and execution mode utilization, it can be applied to various applicable field of the present utility model completely, for those skilled in the art, can easily realize other amendment, therefore do not deviating under the universal that claim and equivalency range limit, the utility model is not limited to specific details and illustrates here and the legend described.
