Description of drawings
Fig. 1 is the utility model main control circuit frame principle figure;
Fig. 2 is the utility model PLC control principle figure.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
The utility model has been installed intelligence control system in switch cubicle, its main solution is that a measure and control instrument is installed on main switch, pass through separating brake and closing coil current signal on switch on the measure and control instrument, detect, can detect the quantity of state of electric current and switch, the voltage of exporting by the voltage transformer that connects on the switch main bus bar just can detect the voltage on the switch in addition, by detecting to such an extent that carry out data transaction in the voltage and current instrument, calculate power electric energy and relevant parameters of electric power.Disposed communication interface on the instrument in addition, all data of service entrance switch are after being input to measure and control instrument, and instrument can demonstrate the electric current of switch, the quantity of state of voltage data and switch.Require and the detection requirement according to different circuit, be input on the PLC by self-compiling program, PLC also can carry out communication by PORT COM and touch-screen, and special software in the touch-screen is split to close and carried out the control of divide-shut brake.Also can be connected by the PLC PORT COM in addition, just can in the control room, detect the measurement with parameters of electric power with host computer, and the control that can switch amount and the control of divide-shut brake.
As shown in Figure 1: by the process of the voltage transformer on main switch bus no-load voltage ratio, being input to measure and control instrument detects, just can on instrument, demonstrate current voltage by the voltage signal that detects, switching winding in the switch outputs on the measure and control instrument, just can obtain on measure and control instrument showing that basis detects to such an extent that whether electric current is just connected and can be detected the on off state division and combination in addition by the magnitude of current that detects.Outputing on the measure and control instrument of switch closing coil can be detected on off state, is input among the PLC by the PORT COM of measure and control instrument, and the processing by PLC again is connected on the touch screen to be split to close by touch-screen by PLC and carries out the control of divide-shut brake; Also can be connected with computer, just can carry out long-range control and display switch amount, electric current, voltage, power and electric energy at computer by the PLC communication interface.
PLC can carry out a plurality of switches and control and detect, can control 7 switches, switch in the regulator cubicle can be controlled by PLC, reach the whole concentrated switch that connects other by a PLC of cupboard, the state of switch amount, electric current, voltage, power and electric energy show and can be by PLC on touch screen, by touch-screen the state of other switches is controlled, in the detection and control of switch amount, when occurring surpassing rated current, the software that is set in PLC in advance will issue instructions to switch, and switch just can carry out separating brake automatically in official hour.The utility model can be controlled 1 road inlet wire and 7 tunnel outlets.
As shown in Figure 2, supposing has 2 controlled switches except that main switch, is respectively 2# switch and 3# switch; It is the small PLC of TWDLCAA40DRF that PLC adopts model.Measure and control instrument is a main switch switching winding output signal 102, enter into the I0.0 node of PLC, information such as the electric current of main switch switching winding, on off state are input to after PLC handles, control by touch-screen again, the signal of control at the divide-shut brake coil that is transferred on the switch.When the switching winding dead electricity, the iron core cut-off switch of coil is with regard to separating brake; Setting is closed a floodgate as touch-screen, and coil is charged, the iron core adhesive, and switch will close a floodgate.Just can split the pass by above control and carry out long-range control, reach the intelligentized control of switch.PLC needs electric current that signal gives switch that signal is transferred to the electric current of divide-shut brake, reaches the requirement of controlling.PLC also can not only control main switch also can control other switch, reaches a PLC and can control a plurality of switches.The Q0.2 node outputs to the separating brake that shunt opening coil on the 2# switch can carry out switch, outputs to the combined floodgate that closing coil on the 2# switch just can carry out switch by the Q0.3 node; Equally, by the I0.1 node in the signal 103 to PLC of main switch closing coil output, information such as the electric current that input is relevant, voltage, on off state are input to after PLC handles, output to the separating brake that switching winding on the 2# switch can carry out switch by the Q0.6 node, output to the combined floodgate that closing coil on the 2# switch just can carry out switch by the Q0.7 node.At RS485+ on Fig. 2 and RS485-is two nodes of PORT COM on the PLC, can be the transfer of data of PLC to touch-screen, can split the divide-shut brake that the pass is controlled by the software of touch-screen setting, can be two nodes of PORT COM on the PLC also by RS485+ and RS485-, output on the computer, carry out long-range control on computers.Two end points of L on the PLC, N are to be input to such an extent that alternating current 220V voltage is supplied with the PLC power supply by the outside.Be input to after PLC goes up the I0.2 node data and handle by measure and control instrument in addition, carry out data by the I0.3 node again and output in the measure and control instrument and show.When the electric current of any switch surpassed rated current, PLC sent instruction to the switching winding on this switch, and this switch is carried out separating brake, guarantees the safety of switch.
The utility model has connected the detection contact of switching value and the voltage and current of detection on main switch, pass through the electric current and the voltage of measure and control instrument sense switch when divide-shut brake.Just can carry out separating brake automatically when electric current surpasses rated current, just can in time feed back on instrument as the phase failure occurring when detecting voltage, the processing that just can carry out the switch separating brake disconnects main switch.
