Described locking annex 200 also includes: binding ring 3, locking-type plug 5 and locking groove 6, and described binding ring 3 is a hat, the lateral surface of locking-type plug 5 and the described binding ring 3 common geometrical clamps that form temporary ground wire; Label chip 7 is fixed on an end of close medial surface on the locking-type plug 5.
Described locking groove 6 is arranged on the left and right sidewall of locking-type plug 5, is the groove that is concaved by left and right sidewall.
Described detection blocking mechanism 100 also includes, shell 1, and the shell 1 of described detection blocking mechanism 100 includes working face and stationary plane, and stationary plane is provided with installing hole 11; Working face is provided with the opening of fixed socket 10, and described fixed socket 10 has shape and the suitable blind hole of size with described locking-type plug 5; Deadlock lever 15 is arranged in the inner chamber of shell 1, and is positioned at the right side of fixed socket 10, and the right side wall of described fixed socket 10 has the through hole that deadlock lever 15 is come in and gone out; Label read head 16 is positioned at the below of fixed socket 10, is arranged in the inner chamber of shell 1.
The periphery of described deadlock lever 15 is provided with and can orders about deadlock lever 15 spring 14 of location automatically.
The outer end of described deadlock lever 15 is provided with the release lever 2 of the position of the described deadlock lever 15 of scalable.
The shell working face of described detection blocking mechanism 100 is provided with emergent unlock hole 9, and described emergent unlock hole 9 is positioned at the side of described deadlock lever 15; Emergent trip lever 13 is arranged in the inner chamber of shell 1, with emergent unlock hole 9 over against the position.
The shell working face of described detection blocking mechanism 100 is provided with more than one running LED 8.
Described electromagnet lock pin 12 is arranged in the inner chamber of shell 1, and the centerline direction of the centerline direction of described deadlock lever 15 and electromagnet lock pin 12 is perpendicular.
Described label chip 7 is a kind of chip with RFID coding, and RFID chip code value is as the identity code of temporary ground wire, and label read head 16 is RFID coding read head, the RFID chip code value identification ground wire on the reading tag chip 7.
During use, locking annex 200 is fixed on the temporary ground wire, detects blocking mechanism 100 and can be fixed in the ground wire cabinet or on the wall.Control circuit realize the RFID read head read sign indicating number with control electromagnet lock pin 7 upspring or indentation and with external communication function (accompanying drawing 4).
As Fig. 2,5, described control circuit includes cpu controller, RS485 telecommunication circuit, RFID and adopts decoding circuit and solenoid driver circuit; Cpu controller is by transmission of RS485 telecommunication circuit and received signal, and RFID adopts the code value of decoding circuit reading tag chip 2; Cpu controller sends and instructs to solenoid driver circuit, and drive magnet lock pin 12 outwards ejects or inwardly withdrawal.
When the plug that is fixed on the locking annex 200 on the ground wire being inserted in the socket that detects blocking mechanism 100 (accompanying drawing 4), the position is close between RFID read head 16 and the RFID chip 7, RFID read head 16 can read the code value of RFID chip 7, realized the identification of ground wire, simultaneously because the effect of spring 14 makes deadlock lever 15 be inserted into automatically on the position of locking groove 6.When control circuit control electromagnet lock pin 12 shrinks back, at this moment allow deadlock lever to be separated with locking groove by the rotation release lever, can take out the locking annex, be grounded the unlocking function of line; When control circuit control electromagnet lock pin 12 ejected, release lever rotation at this moment was motionless, can't separate deadlock lever with locking groove, thereby realize the blocking function of earth connection.Control circuit comes except the ejection of reading sign indicating number and control electromagnet lock pin that realizes the RFID read head or shrinks back the function, also realizes and external communication function (accompanying drawing 4,5).
All temporary ground wires are all installed described locking annex in the power plant of transformer station, described RFID chip is installed in the locking annex, described detection blocking mechanism be installed in the ground wire cabinet or the wall of ground wire toolroom on, all detection blocking mechanisms are communicated by letter with shutting device to prevent mistakes in microcomputer by order wire, and every earth connection is corresponding one by one with a detection blocking mechanism.When the locking annex on the earth connection is inserted on the detection blocking mechanism, the reading terminal that detects on the blocking mechanism will be read RFID chip code value, discern pairing temporary ground wire according to code value, and the RFID code value of being read is issued shutting device to prevent mistakes in microcomputer.Shutting device to prevent mistakes in microcomputer can be realized locking or release to locking annex (temporary ground wire) by sending order to detecting blocking mechanism.Thereby realized that shutting device to prevent mistakes in microcomputer is to the identification of temporary ground wire and the function that unblocks.
When transformer station, power plant need use earth connection to carry out execute-in-place, the simulation bill after date, shutting device to prevent mistakes in microcomputer sends the ground wire detection blocking mechanism of ordering to correspondence and carries out the release temporary ground wire, temporary ground wire is taken operation site from the ground wire toolroom carry out the ground connection grid switching operation.After inspection operation finished, if ground wire is not removed, shutting device to prevent mistakes in microcomputer was not received the state information that the ground wire of ground wire detection blocking mechanism is taken back, and will forbid the operation that next step send electricity, thereby has realized preventing to send with earth connection the misoperation of electricity.When earth connection is removed and brings back on the detection blocking mechanism that is inserted into the ground wire toolroom, ground wire detects blocking mechanism will carry out locking to earth connection, preventing that temporary ground wire is chaotic uses, and just earth connection is carried out release after having only shutting device to prevent mistakes in microcomputer to send unlock command.
The utility model also has other concrete form of implementation.In a word, so long as do conspicuous change according to prompting of the present utility model, and other every change that does not break away from essence of the present utility model and make, all should be included within the described scope of claim.
