Description
Technical field:
The utility model relates to a kind of real information carrying means of hanging of the ground wire that is installed in the ground wire state on the transmission of electricity cable that is used to detect.
Background technology:
Electric system is in electric substation or transmission of electricity cable maintenance process, for preventing maloperation it is powered, usually adopt the mode of cable by ground connection made its short circuit, to guarantee the safety of maintainer and power-supply unit, and after electric substation or transmission of electricity cable maintenance task were finished, ground wire must complete removal.Yet; because the transmission of electricity cable of electric system has also shuttle back and forth characteristic between mountains and rivers and high-rise of span cable long and that have; need be provided with tens even hundreds of winding ground wire during these cables in maintenance; all need many people and operate for a long time and just can finish and remove these ground wires; so in demolishing process; ground wire occurs through regular meeting and leak the phenomenon of tearing open; if even have only a ground wire not have split removing; serious accident can take place because of short circuit in this cable when sending electricity, bring serious loss to power supply department.
" preventing the switching on earth wire automaton " of No. 1043231 bulletins of Chinese patent is exactly a solution that proposes at the problems referred to above.Control device that this patent proposed adopts ground wire to the direct short circuit of three-phase power line and form the uneven formula bandpass network of a kind of four ends, makes this network produce resonance to control signal and carries out the structure of gating.Its meaning be want to utilize when under the situation that ground wire does not have to remove during energising the mode of switch block cisco unity malfunction prevent the generation problem of described accident.And " the anti-band of electric system ground wire make and break circuit interlocking device " that Chinese patent is announced for No. 2144889 also is a kind of equipment that ground wire does not have dismounting just to power that is used to solve, this device or equipment adopt two parts element, wherein a part of element is connected with breaker control circuit, another part element is connected with ground wire, and adopts a metalwork to make conductive material between two parts element.
The phenomenon of just powering when though above-mentioned two patented technologies can avoid ground wire to be connected with cable, but its employed device must be installed on each switch block, and adjacent two switch blocks apart from each other under normal conditions, if a ground wire is arranged not to be removed, even can reflect the particular location that also needs further to seek this ground wire place, bring many inconvenience to operating personnel by switch block; Simultaneously, the device that above-mentioned patent proposed also needs the operating process of relative complex when installation and removal, and device itself also has complicated structure, can further increase the cost of overhaul undoubtedly.
In addition, Chinese patent has also been announced a kind of " preventing the device of switching on earth wire " for No. 2119041.This device is by signal power source and differentiates controller, and coupling element is formed.Its meaning is to want to utilize the mode of the size of measuring loop current to come alert whether can be this cable line power supply.With regard to supply network, under the situation that does not have power supply, be difficult to determine loop current, and when not just power supply of dismounting of ground wire, even after power supply, can measure the size of loop current, power-supply unit has been caused inconceivable economic loss, so the identification device of this kind structure is difficult to be widely used.
Summary of the invention:
Task of the present utility model provides a kind of real information carrying means of hanging of ground wire that can detect ground wire position and state in real time.
The real information carrying means of hanging of the ground wire that the utility model proposed has the switch block that is connected with the real ground wire that hangs on the transmission of electricity cable and is installed in the housing and control chip that be electrically connected with this switch block, and the information transceiving device that is electrically connected by described control chip, and the battery component that is used to control chip and information transceiving device that electric energy is provided is installed also in housing.In the time of on switch block being installed in ground wire and parts that cable is connected, can send or receive the real extension information of ground wire, also can demonstrate the position at this ground wire place simultaneously by control terminal with the information transceiving device conducting and to remote control terminal.
Described switch block adopts mechanical travel switch.Described information transceiving device is to be made of external modem.
The real information carrying means of hanging of the ground wire that the utility model proposed is only by switch block and control chip, and information transceiving device just to obtain this ground wire be real hang on the cable or removed and the accurate information of position, so, use this device ground wire can not occur and do not have to remove the just phenomenon of power supply, and the very convenient installation of this device, cost of manufacture is also relatively low.
Description of drawings:
Accompanying drawing 1 is the real surface structure synoptic diagram of hanging 1 one embodiment of switch block in the information carrying means of ground wire;
Accompanying drawing 2 is the real surface structure synoptic diagram of hanging information carrying means housing 2 of ground wire;
Accompanying drawing 3 is the real circuit theory synoptic diagram of hanging an embodiment of information carrying means of ground wire described in Fig. 2.
Embodiment:
Referring to Fig. 1 to Fig. 3, these three accompanying drawings provide the real concrete structure of hanging an embodiment of information carrying means of ground wire that the utility model proposes.This device comprises switch block 1 and housing 2, and is installed in battery component 21, control chip 22 and information transceiving device 23 in the housing 2.What switch block 1 adopted is mechanical travel switch, the trip switch comprises the framework 12 that is installed in contact 11 on the clamp 13 and can axial stretching and is used to limit these contact 11 positions, and the spring of 11 returns of the made contact on the installation frame 12 (not providing concrete structure among the figure).When clamping cable with this clamp 13, contracing to recovery under the effect of contact 11 cables and clamp 13 makes switch block 1 conducting.
Control chip 22 in the present embodiment adopts the single-chip microcomputer of AT89C2051 type, modulator-demodular unit adopts the PTR2000 module, when connecting, 20 jiaos of single chip computer AT 89C2051 with modulator-demodular unit PTR2000 1,2,6 jiaos are connected with battery component 21,2,3 jiaos of 3,4 jiaos of connections of modulator-demodular unit respectively of single-chip microcomputer, 12 jiaos of single-chip microcomputer are electrically connected with switch block 1, and its 13 jiaos with modulator-demodular unit 7 jiaos are connected and by resistance R and light emitting diode D ground connection.The utility model can also adopt other parts or device to finish being proposed of task, and these all belong within the protection domain of the present utility model.
