A kind of earth wire pile of identifiable design identity
The utility model relates to a kind of earth wire pile, is specifically related to a kind of transformer station or power plant for identifying the earth wire pile inserting ground wire identity.
The enterprise such as transformer station, power plant in process of production; when interruption maintenance is carried out to equipment; need mounting earth connection to protect personal safety; prevent incoming call suddenly from causing to operating personnel injury of getting an electric shock, meanwhile, the resistance to current level of earth connection of different electric pressure is different; if ground wire wrong plug earth wire pile; light then cause device damage, heavy then injure staff and even cause loss of life or personal injury, cause the pernicious misoperation fault being with ground wire power transmission.
For electric power enterprise, only rely on the sense of responsibility of operating personnel and working attitude to be insecure to stop operate miss, technological means must be taked to prevent the generation of misoperation.To this, most of power-generating enterprises use shutting device to prevent mistakes in microcomputer, are achieved the intelligent management of earth wire by technological means, but after operating personnel take earth connection, or can not guarantee to be articulated on correct earth wire pile, for the operation of equipment leaves potential safety hazard.
Summary of the invention
Technical problem to be solved in the utility model is, overcomes the above defect, provides the earth wire pile of simple, the easy to use, safe effective identifiable design earth connection identity of a kind of structure, the accurate location of the ground wire that can achieve a butt joint.
In order to solve the above technical problem, the earth wire pile of a kind of identifiable design identity of the utility model, comprises pile body, described pile body is provided with and identifies box and ground string holes; Be provided with the indicator light, buzzer, code reader and the radio receiving transmitting module that are connected by control circuit in described identification box, battery be set for control circuit power supply is provided.
As preferably, code reader described in the utility model is arranged on the top identifying box.
The utility model provides a kind of earth wire pile of identifiable design earth connection identity, by arranging identification box on pile body, identify in box by identifying that the relevant apparatus of earth connection identity is arranged on, earth terminal inserts, if the earth connection of mistake, then buzzer warning from ground string holes, indicator light becomes flicker by often bright, if mounting is correct, then indicator light Chang Liang, buzzer stops after ringing a sound.Improve the accuracy of ground wire hitching position with this, in transformer station, power plant, the safety operation of operating personnel provides reliable guarantee, ensure the safe operation of equipment in the enterprise such as transformer station, power plant.
The beneficial effects of the utility model: owing to employing the above structure, the utility model has that structure is simple, easy and simple to handle, accuracy of judgement, the advantage such as safe and reliable.Use the utility model, substantially increase the accuracy that earth connection is installed, earth connection misplug can be prevented, leak and insert, the personal safety of operating personnel when power equipment interruption maintenance can be made to obtain strong guarantee.

Below in conjunction with accompanying drawing, the utility model is described in further detail.
The earth wire pile of a kind of identifiable design identity of the utility model, comprises pile body 1, described pile body 1 is provided with and identifies box 2 and ground string holes 3; Be provided with the indicator light 5, buzzer 6, code reader 7 and the radio receiving transmitting module 8 that are connected by control circuit 4 in described identification box 2, battery 9 be set for control circuit 4 power supply is provided.
As preferably, code reader 7 described in the utility model is arranged on the top identifying box 2.
Embodiment: the earth wire pile of identifiable design identity described in the utility model, as model ZJD-3 type earth wire pile, described identification box 2 is arranged on the below of described ground string holes 3, indicator light 5, buzzer 6, code reader 7 and radio receiving transmitting module 8 is bought from market, and corresponding component is connected with control circuit 4, battery 9 is connected with control circuit 4 again, will load in described identification box 2 with upper-part, in order to improve the sensitivity of reading information, described code reader 7 can be arranged on the top identifying box 2.RFID chip 11(is housed as shown in Figure 5 with the utility model matching used ground wire 10), when certain equipment needs to overhaul, suitable earth connection is chosen by anti-error main frame, and send ground wire hitching instruction to the earth wire pile of relevant device position, ground wire 10 is inserted the ground string holes 3 of described earth wire pile by operating personnel, RFID chip 11 on ground wire aligns (as Fig. 6 with code reader 7, shown in Fig. 7), after described earth wire pile receives instruction, indicator light 5 Chang Liang, code reader reads RFID code value, if the earth connection of mistake, then buzzer warning, indicator light becomes flicker by often bright simultaneously, if mounting is correct, then indicator light continues Chang Liang, and buzzer stops after ringing a sound.So, operating personnel easily can judge the correctness of ground wire hitching, and accident of stopping occurs.
Above embodiment only have expressed a kind of execution mode of the present utility model; but therefore can not be interpreted as the restriction to the utility model the scope of the claims; for the person of ordinary skill of the art; without departing from the concept of the premise utility to do; also can go out some distortion and improvement; as long as employ the above structure, protection range of the present utility model all should be fallen into.
