Description
Technical field
The utility model relates to a kind of ground clamp, relates in particular to the ground clamp that a kind of electric power system is used to prevent the temporary ground wire of electric misoperation.
Background technology
" five anti-" block sytem be China's electric power system to preventing a kind of control system of back brake misoperation in power plant, the transformer station's power transmission and distribution process, mainly be to prevent mistakenly entering charged chamber, prevent mistake drawing switch, prevent on-load drawing disconnecting link, prevent charged hanging ground-wire, prevent to be with ground wire to close disconnecting link with technological means.The back brake misoperation repeats to cause serious accident in electric power system over the years, the particularly misoperation of closing disconnecting link at charged hanging ground-wire and band ground wire, because the mounting or dismounting management to temporary ground wire (being called for short " ground wire ") does not have complete technical equipment, can't accomplish that enforceable ground wire is joined like that according to interlock carry out mandatory administration in the whole anti-error locking system, now still need to rely on field personnel's sense of responsibility and working attitude to reduce error.Because the installing ground wire is in order to protect the safety in the electric equipment maintainer operating process, if the ground wire installation position is not right, then not have protection personnel's effect; Simultaneously, if finish the untimely dismounting ground wire in back in electric equipment maintenance, then can cause the serious accident that the band ground wire closes disconnecting link, therefore preventing charged hanging ground-wire and band ground wire, to close this misoperation of disconnecting link be one of key of relation change distribution safe operation.
The employed temporary ground wire of electric power system mainly is made up of ground clamp, cable, ground wire pile crown etc., and wherein, ground clamp is used for being articulated on the power transmission line, and the ground wire pile crown is used for fixing in the ground wire stake of wanting earthing position, and cable connects ground clamp and ground wire pile crown.Generally, on all prior fixedly connected ground clamp in the two ends of cable and the ground wire pile crown, when carrying out the electric equipment maintenance, take near the electric equipment that needs hanging earthing conductor by the staff, be articulated on the earth point or suitable earth point of appointment, to guarantee service work personnel's safety.At present, on temporary ground wire, mostly adopt the mode of lettering or numbering to identify the difference ground wire, but lacking technological means allows anti-error locking system or other automated system discern and manage ground wire, more can't accomplish articulating and removing of real-time inspection and management temporary ground wire in site of deployment, the work of the dismounting ground wire after particularly maintenance finishes at electric equipment, if not having perfect technological means all ground wires of conducting a compulsory examination has all removed, in case transmission line send, the ground wire that does not then have to remove will cause serious misoperation fault, cause huge equipment loss and economic loss.
Summary of the invention
Therefore, technical problem to be solved in the utility model is the deficiency that overcomes on the prior art, provides a kind of and misoperation can not occur, can carry out effectively traditional thread binding provisionally management and the communication of the real-time radio signal of telecommunication, the ground clamp of easy construction, convenient management torn open.
The technical scheme that the utility model adopted is: a kind of ground clamp of anti-misoperation locking, include can be easily be connected ground wire-connecting device that ground wire connects and remove and the cable fastener that is connected with cable, wherein, be provided with also on the described ground clamp whether detectable transmission line exists and with the outside controller circuitry that sends of detectable signal, described controller circuitry is packaged on described ground wire-connecting device or the cable fastener.
Preferably, described ground wire-connecting device is a metal clip or metal hook.
Described controller circuitry is packaged on the described ground wire-connecting device.
The beneficial effects of the utility model are: the utility model is as the critical component on the electric power temporary ground wire, because whether include the switch detecting element detects temporary ground wire and installs and removes, and the microprocessor CPU system that can install and remove signal processing to this, information after can handling CPU in addition is transferred to the outside anti-error locking system or the radio transceiver chip of other automated system by wireless system, so the utility model can cooperate anti-error locking system that the electric power temporary ground wire is controlled and managed.In carrying out electric equipment inspection operation process, can be used as interlock and its operating process is set by anti-error locking system or other automated system.For example, at first will be before the maintenance electric equipment at the appointed place hanging earthing conductor, can send the instruction of installing ground wire in advance to the temporary ground wire of appointment by anti-error locking system, operating personnel take this temporary ground wire to on-the-spot, ground clamp is articulated on the transmission line that will install, at this moment, the switch detecting element of ground clamp detects ground clamp and is attached to the position signalling on the transmission line and sends the information of ground wire installing by radio receiving transmitting module to anti-error locking system, and anti-error locking system writes down this information and preserves; After the electric equipment maintenance finishes, before circuit send electricity, anti-error locking system will check whether the ground wire of above installation is all removed, promptly constantly detect the position signalling that ground clamp is sent by anti-error locking system, if ground clamp is taken off from transmission line, then the switch detecting element is surveyed less than transmission line is arranged, send the not position signalling on transmission line of ground clamp by the radio receiving transmitting module on the ground clamp to anti-error locking system, show the ground wire of installation split except, thus, when the installing of all ground wires that write down in anti-error locking system record all detect less than after, then anti-error locking system can send the operation of electricity, otherwise, can not send the operation of electricity.So, can effectively prevent to send electric caused misoperation fault because of there being ground wire not remove.
