Description
Technical field:
The utility model relates to a kind of pressing plate monitoring host computer with distant place switching function, belongs to electricity substation end Job site communications and technical field of automation.
Background technology:
Along with the propagation and employment of intelligent substation in electrical network, transformer station implements non-attendant operation's management has become current main management mode.
Transformer station possesses unattended operation condition, but in the transformer station of electric power system, the switching still manual operation at the scene of second protection pressing plate.In traditional various protections, pressing plate is used to be switched on or switched off certain loop.The output clamping of protection is exactly the brace being switched on or switched off exit relay or breaking coil energized circuit.If before finding that pressing plate is connected, its two ends have voltage that certain grade of relay protective scheme loop action before output clamping is then described, just have electric current flow through once connection, make exit relay or breaking coil action tripping operation.Therefore; General Requirements connects the voltage at pre-test once two ends at protection exit pressing plate; the exception or defect that may cause circuit breaker trip whether is had with check protection; the incorrect operation behavior of Timeliness coverage protection; prevent and avoid the generation of false tripping circuit breaker event, this just needs operating personnel to complete this operation to scene.In case of mode adjust, line live-line work, the situation such as when device sends out abnormal signal, also needs to send operator to carry out the operation of pressing plate switching to scene.Will be occasioned a delay time, labor intensive, material resources like this, causes loss economically.And operator on duty can not understand the state of each pressing plate of transformer station in real time, the running status of transformer station can not be grasped comprehensively.Switch pressing plate and there is higher evolutionary operator probability, cannot communication automation system be realized, reach the function that distant place switching controls pressing plate.Changing this situation as wanted can only be that all microcomputer protecting devices at full station are replaced by the novel protector with pressing plate remote management capability; series of problems can be brought like this: with high costs, replacement cycle is long to be needed to have a power failure for a long time, DTU and main website need to reconfigure, all Protection parameters need again to adjust, because Social benefit and economic benefit reason cannot realize at present.
Utility model content:
The purpose of this utility model is to overcome the deficiency of above-mentioned prior art and provides a kind of automatization level that improves, failure rate is low, easy to maintenance, improve supervision quality and operating efficiency, reduce rate of failure and maintenance cost, the safe and reliable pressing plate monitoring host computer with distant place switching function.
The purpose of this utility model can be reached by following measure: a kind of pressing plate monitoring host computer with distant place switching function, it is characterized in that it comprises central processor unit, central processor unit is connection data collecting unit, control output unit, communication unit respectively, communication unit connects the RS485 communication port of transformer station DTU respectively, data acquisition unit connects 1 transducer, 2 transducers, 3 transducers respectively, controls output unit and connects 1 pressing plate, 2 pressing plates, 3 pressing plates respectively.
The utility model can produce following good effect compared with the prior art: enforcement of the present utility model, eliminate the traffic time of execute-in-place, save a large amount of manpower and materials, improve the operating efficiency of live line working, higher Social benefit and economic benefit can be brought for electric company again.It has
1) realize the centralized management of all transformer substation protection pressure plates, compensate for the deficiency that protection waits the management of original system pressing plate.
2) realize the long-range switching of pressing plate, improve automatization level, be beneficial to personnel reduction and enlargement.
3) realize the control of operator on duty to situation in station, strengthen the operational management to unattended station, improve supervision quality and operating efficiency, reduce rate of failure and maintenance cost.
4) self-organizing system independent operating, failure rate is low, easy to maintenance.
5) good compatibility, the Microcomputer Protection of accessible any producer.
Accompanying drawing illustrates:
Fig. 1 is structured flowchart of the present utility model;
Embodiment:
Below in conjunction with accompanying drawing, embodiment of the present utility model is elaborated:
Embodiment: a kind of pressing plate monitoring host computer (see Fig. 1) with distant place switching function, it comprises central processor unit 1, and central processor unit 1 is connection data collecting unit 2, control output unit 3, communication unit 4 respectively.Communication unit 4 connects the RS485 communication port 5 of transformer station DTU respectively, and data acquisition unit 2 connects 1 transducer 7,2 transducer 8,3 transducer 9 respectively, controls output unit 3 and connects 1 pressing plate 10,2 pressing plate 11,3 pressing plate 12 respectively.
The two ends access data collecting unit 2 of 1 transducer 7, the two ends access data collecting unit 2 of 2 transducers 8, the two ends access data collecting unit 2 of 3 transducers 9, 1 pressing plate 10, 2 pressing plates 11, the pressing plate transfer of data of 3 pressing plates 12 is to data acquisition unit 2, pressing plate data are amplified by data acquisition unit 2, coded transmission is to central processing unit 1, pressing plate data generate TTL Signal transmissions to communication unit 4 after central processing unit 1 carries out data processing, communication unit 4 converts RS485 signal to the TTL signal received, transformer station DTU is transferred to by the RS485 communication port 5 of transformer station DTU, complete the collection to pressing plate data and transmission.The pressing plate data collected are sent to transformer station DTU by the utility model, enter electric company's local area network (LAN), the dispatching automation main website of local side shows the pressing plate state at each station according to configuration period, and can send instructions down as needed long-range switching controls corresponding pressing plate deciliter to pressing plate monitoring host computer.
The pressing plate switching order that main website issues is transferred to communication unit 4 by the RS485 communication port 5 of transformer station DTU, communication unit 4 converts RS485 signal to TTL Signal transmissions to central processing unit 1, central processing unit 1 generates control signal according to the TTL instruction received and is transferred to control output unit 3, control to export to 1 pressing plate 10,2 pressing plate 11,3 pressing plate 12 after the control signal sent here by central processing unit 1 of output unit 3 is amplified, realize pressing plate deciliter.
