Description
Technical field
The present invention relates to a kind of control device that is used for detecting in real time state of ground wire, can be applicable on the earth connection of electric power system grid switching operation device.
Background technology
Microcomputer anti-error operating system has been widely used in the electric power system, this type systematic installs the forced blocking that lockset is realized equipment additional on power equipment, the switching of main frame or anti-error key control lockset by embedded anti-misoperation logic effectively prevents the generation of all kinds of misoperation faults.The upgrading of substation equipment also makes the supervisory control system of most of transformer station possess the ability of real-time sense switch, disconnecting link and ground connection cutter state.
But because the present microcomputer anti-error operating system overwhelming majority can not real-time fully checkout equipment state, the attaching state of ground wire especially temporarily.Owing to the special occupation mode of interim ground wire, supervisory control system also fails to detect in real time its state in addition.Owing to above reason, cause the part operation personnel in the grid switching operation process, to have act of violating regulations, cause misoperation.According to the statistics of China Electric Power Research Institute, in all kinds of misoperation faults, the misoperation relevant with ground connection account for all kinds of misoperations quantity 60%, wherein be with ground wire (cutter) to close a floodgate and in five class misoperation faults, occupy the first.
Based on above reason, many electric power safeties producer begins to be conceived to the safe handling of ground wire, has developed various forms of ground wires management cabinets, with the strict control ground wire.But this type systematic is the storage configuration of management ground wire mostly, then not too payes attention to for prior attaching state.Therefore still there is big leak in the ground wire management work of electric power system.
Summary of the invention
For solving in the prior art state of ground wire is detected the deficiency that exists, the invention provides a kind of ground lane controller that can detect ground wire attaching, standby (comprise and remove and take out) in real time and deposit three kinds of states, its technical scheme of taking is:
This controller comprises metal shell, be fixed on the communication antenna and the ground wire of housing front end, be fixed on the ground the end of a thread and the card reading antennas of housing rear end and be fixed on the interior main circuit board of housing, keypad and battery, main circuit board is provided with by one-chip computer module and the communication control module that is connected with one-chip computer module respectively, the Card Reader control module, the circuit that last electric control module and indicator light are formed, communication control module connects communication antenna, the Card Reader control module connects card reading antennas, keypad is provided with power on button and the reset key that is connected with last electric control module respectively, have the reset key via hole on the housing sidewall, fore-set via hole and indicator lamp hole, reset key is aimed at the reset key via hole, the button that powers on is aimed at the fore-set via hole, indicator light is embedded in the indicator lamp hole, but be located at fore-set roof pressure in the fore-set via hole button that powers on, the fore-set spring that is socketed in above the fore-set can make fore-set realize resetting, when power on button or when resetting of fore-set roof pressure, can trigger one-chip computer module and last electric control module work, Card Reader control module control this moment card reading antennas reads the coded message of ground wire different conditions, and coded message is sent one-chip computer module control circuit outage then by communication control module control communication antenna.
Card reading antennas is circular, and it is enclosed within on the round platform of housing rear end, and ground the end of a thread that front end has a circular hole passes card reading antennas and is fixed on the round platform, has the fore-set hole that can pass fore-set and the reset key hole of aiming at the reset key via hole on the card reading antennas.The bottom of housing has the slot tag that can place the ground wire label.
This controller is pushed the button that powers on by fore-set, make it trigger the one-chip computer module and the last electric control module work of main circuit board, circuit is powered on, read ground stud or deposit position coding by Card Reader control module control control card reading antennas, and send by the information of communication control module control communication antenna with state of ground wire, automatically close then, the information of state of ground wire inserts the electric power system internal communication network again by the radio fest and control network subsequently, and main frame detects in real-time report to transformer station, main frame and dispatching patcher are detected in the power transformation work area.
This controller with ground wire as detecting target, can detect ground wire attaching, standby (comprise and remove and take out) in real time and deposit three kinds of states, can realize the fail safe of state of ground wire supervision, increase grid switching operation, and system can work independently, therefore can be used as replenishing of anti-misoperation system, reducing the misoperation that brings because of the imperfection of microcomputer anti-error operating system may.
