Background technology
In the operation order workflow in the electric power system, need the dispatcher at the scene the transformer station of administering to be carried out practical operation, need operator and guardian to reach the spot simultaneously in the operating process, one man operation one people monitoring.Along with after each transformer station carries out unattended station administration, each operation utensil all has been placed on base station, and when there was service work in transformer station, operating personnel were carried into required utensil transformer station again and use.Earth connection in the operation utensil is one of the utensil that must use in the maintenance repair process of operating personnel, but because operation field does not have the special-purpose storage facilities of earth connection, causes earth connection to leave about everywhere, the inconvenience of taking during use; After upkeep operation is finished, also can exist because the maintainer neglects and leak the phenomenon of tearing ground wire open in addition, cause the power equipment band ground wire in the electric power system to send electricity, cause great potential safety hazard.
The utility model content
The utility model technical issues that need to address provide a kind of can the monitoring grounding wire operating position, guarantee the earth connection management devices of maintainer and device security.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is as follows.
Intelligence earth connection management devices, comprise for the storage rack of depositing earth connection temporarily, described storage rack comprises base and is used for depositing the plate of depositing of earth connection perpendicular to ground, deposit plate and be installed in base top by support, described front of depositing plate is provided with several hooks that is used for hanging earth connection; Also be provided with the testing agency of whether hanging for detection of earth connection, the display module that is used for showing earth connection use state on the storage rack, reclaim the not full-time alarm module that gives the alarm and be used for sending the control module that controlling alarm is instructed for working as earth connection, the output of described testing agency is connected with the input of control module, and the output of control module is connected with alarm module with display module respectively; Described testing agency is corresponding with described hook and by hook control.
The concrete structure of described testing agency is: described testing agency is arranged on the back side of depositing plate and links up with corresponding position, hanging handle end, and testing agency is used for monitoring to link up with the displacement transducer of end position variation or/and for detection of the torque sensor of linking up with stress; When described testing agency is displacement transducer, the hanging handle of hook and deposit the spring that is provided with between the through hole that plate is used for passing hanging handle be used to the hook that resets.
The concrete structure of described display module is: described display module comprises the charactron that is arranged on the display screen of depositing the plate front and lays respectively at each hook top.
The concrete structure of described alarm module is: described alarm module comprises and is arranged on the phonetic alarm of depositing the plate front or/and lay respectively at each charactron top and the corresponding indicator light of hook.
The concrete structure of described control module is: described control module comprises the Industry Control single board computer, the input of described Industry Control single board computer connects the signal end of displacement transducer and torque sensor, and the output of Industry Control single board computer is connected with display screen, charactron, phonetic alarm and indicator light respectively.
Because the technological progress of having adopted technique scheme, the utility model to obtain is as follows.
The utility model can effectively be monitored in maintainer's operation tandem docking ground wire quantity and numbering, after operation is finished, when earth connection is not regained fully, numbering corresponding alarm bell with earth connection begins to report to the police, remind the operating personnel to still have earth connection not regain, after regaining, this earth connection is suspended on the relevant position, report to the police and just eliminated, thereby guaranteed that each power equipment in the electric power system does not have the existence of earth connection when putting into operation, guarantee personal safety and the device security of transformer station's field service personnel.
Storage rack in the utility model is used for depositing earth connection, storage rack adopts base and deposits the combining structure of plate, guaranteeing that the maintainer picks and places and observe easily on the basis, for the installation of testing agency, display module, alarm module and control module provides the foundation.
When testing agency adopts torque sensor, can judge whether to be hung with ground wire according to the stress of hook hanging handle, when hook was hung with earth connection, the hook hanging handle was subjected to downward power, when torque sensor has detected the moment generation signal was passed to control module; When not having earth connection, torque sensor detects less than torque signals on hook, and control module then can be judged and do not hang earth connection on the hook.Testing agency can also adopt displacement transducer to detect the location status of the hook that hangs earth connection, when being hung with earth connection on the hook, hook moves down under the effect of earth connection gravity, displacement transducer passes to control module after detecting downward displacement, can judge and be hung with ground wire on the hook; When not having earth connection, the hanging handle of hook will be linked up with hanging handle and reset under the effect of back-moving spring on hook, and displacement transducer detects shifting signal not in place, and control module then can be judged and do not hang earth connection on the hook.
The display screen of display module be used for to show whole deposit service work begins before, prepare altogether on the plate to have how many bar earth connections, service work begin total how many bar earth connections in back use and service work finish after information such as how many bar earth connections of withdrawal; Certainly can also show information such as the temperature of earth connection storage environment and humidity on the display screen.The charactron of display module is used for showing the numbering of earth connection that hook hangs correspondingly, so that the maintainer can find earth connection correspondingly fast in operation process.
Phonetic alarm in the alarm module is used for reporting other unreclaimed earth connections when article one earth connection is regained, and to guarantee the maintainer all earth connections is regained.Whether the earth connection that the indicator light in the alarm module is used to indicate on correspondingly the hook is regained, and when not regaining after earth connection uses, indicator light can be lighted always, reminds earth connection that the maintainer should link up with less than withdrawal.
The Industry Control single board computer of control module is used for the information according to displacement transducer and torque sensor detection, operating position and withdrawal situation to earth connection judge, and control display screen in real time, the show state of charactron, phonetic alarm and indicator light.
