Embodiment 1
From Fig. 1～Fig. 3 as can be known, the utility model comprises closure plug 1 and detects blocking mechanism; Closure plug 1 is provided with the earth connection through hole; Closure plug 1 top is provided with locking clamp 6, and label chip 7 is equipped with at the middle part, and has obturator hernia 8;
Detect blocking mechanism and comprise casing 3, deadlock lever 13, electromagnet 12, label read head 10, control circuit; Housing 3 sidepieces are provided with the groove that cooperates with closure plug 1, and groove top is provided with locking recess 9, detect blocking mechanism housing 3 bottoms and have power signal line manhole appendix 4, and sidewall has emergent unlock hole 2, and power supply indicator 5 is housed; Label read head 10 and electromagnet 12 are equipped with in housing 3 inside, and deadlock lever 13 is fixed on the motion end of electromagnet 12; Label read head 10 and electromagnet 12 connect control circuit.Housing 3 outer walls have emergent unlock hole 2, and emergent trip lever 11 is equipped with in the corresponding position of housing 3 inner emergent unlock holes 2.
Described label chip 7 is for having the chip of RFID coding, and RFID chip code value is as the identity code of temporary ground wire; Label read head 10 is RFID coding read head, the RFID chip code value identification temporary ground wire of reading tag chip 7.
Each root earth connection 14 in transformer station, the power plant is the corresponding temporary ground wire locking device above-mentioned with a cover all, earth connection 14 passes the earth connection through hole of closure plug 1, closure plug 1 is installed on the earth connection 14, the detection blocking mechanism is installed in the ground wire cabinet or on the wall of ground wire toolroom, closure plug 1 is corresponding one by one with the detection blocking mechanism; All detection blocking mechanisms are all communicated by letter with shutting device to prevent mistakes in microcomputer by order wire.
The utility model temporary ground wire locking device is when closure plug 1 is inserted into when detecting in the groove of blocking mechanism housing 3 sidepieces (such as Fig. 4), the locking clamp 6 of closure plug 1 is installed in the locking recess 9 that detects blocking mechanism, the label chip 7(of closure plug is the RFID chip) with to detect blocking mechanism label read head 10(be the RFID reading terminal) position is corresponding, deadlock lever 13 is corresponding with the obturator hernia 8 of closure plug 1.The RFID reading terminal will read the code value of RFID chip, identify corresponding temporary ground wire according to code value, and the RFID code value of reading is sent to shutting device to prevent mistakes in microcomputer.Shutting device to prevent mistakes in microcomputer is by sending order to detecting blocking mechanism, realization is temporary ground wire to closure plug 1() identification, the motion end of simultaneously control circuit control electromagnet 12 stretches out, deadlock lever 13 is inserted in the obturator hernia 8 on the closure plug 1 automatically, deadlock lever 13 can't bounce back, 1 motion of restriction closure plug, because the locking clamp 6 of closure plug 1 embeds latch groove 9, so that closure plug 1 with detect blocking mechanism and can't separate, thereby realized the blocking function of earth wire 14.
When the needs such as transformer station, power plant use temporary ground wire to carry out work on the spot, shutting device to prevent mistakes in microcomputer sends the ground wire detection blocking mechanism of ordering to correspondence and carries out the temporary ground wire release, when control circuit control electromagnet 12 is in retracted mode, deadlock lever 13 retractions, closure plug 1 is separated with the detection blocking mechanism, the temporary ground wire of release is taken off from detecting blocking mechanism, take operation field and carry out the ground connection inspection operation.After inspection operation finishes, temporary ground wire is removed, sent back to the temporary ground wire toolroom and insert the detection blocking mechanism, detect blocking mechanism earth wire is carried out locking, then send the electricity operation.If temporary ground wire is not removed and sent back to, then shutting device to prevent mistakes in microcomputer can't receive that ground wire detects the information of the ground wire blocking of blocking mechanism, will forbid sending the electricity operation, has effectively prevented from sending with earth connection the pernicious misoperation of electricity.Control circuit comes except the reading code that realizes the RFID reading terminal and the ejection of controlling the electromagnet lock pin or shrinks back the function, also realizes the function with PERCOM peripheral communication.
Should be noted that at last: above embodiment is used for the explanation the technical solution of the utility model and is not intended to limit; the those skilled in the art makes amendment to execution mode or the part technical characterictic is equal to replacement; and do not break away from the essence of technical solutions of the utility model, all should be encompassed within the utility model scope required for protection.
