Abstract
The invention relates to an acousto-optic alarming device of an earth wire, which is used for preventing misoperation in power industry. The acousto-optic alarming device of the earth wire comprises an automatic alarming device and a wireless trigger device; the automatic alarming device is arranged on the earth wire, and the wireless trigger device and at least one automatic alarming device form mutual control. The automatic alarming device is added to the tail part of the existing earth wire, so that sound and flash can be automatically emitted to remind a maintainer to remember to dismantle the earth wire when the maintenance work is finished. The wireless trigger device can carry out a one-to-more control mode on the automatic alarming device, so that the multi-point automatic alarming devices of a plurality of points can be triggered at the same time, and the maintainer can be effectively reminded to dismantle all earth wires. The acousto-optic alarming device is convenient to install and use, and is free from the improvement of the existing earth wire, so that the workload is reduced. The acousto-optic alarming device has great practical and popularization values.
Description
Technical field
The present invention relates to the warning device that the power industry anti-misoperation is used, specifically the ground wire acoustic-optic alarm with ground wire combined floodgate usefulness appears in a kind of electric substation that prevents.
Background technology
Through retrieving relevant patent documentation, not yet retrieve the ground wire acoustic-optic alarm identical with structure of the present invention at present.At present electric system, electric substation are widely used ground wire; The caller that grounding wire mounting is located at equipment in the maintenance repair work or circuit to, as the last barrier that ensures workmen's safety.Have the fool proof measure normal operation of ground wire ground lock now, and include ground lock in the monitoring anti-error system.In fact not every ground wire can both be included the monitoring anti-error system in by ground lock, and a large amount of ground locks has also increased the possibility of DC earthing, so for the accident that prevents from closing a floodgate with ground wire occurs, except adopting " technical precaution ", also adopt " people's air defense " in the reality.Because electric substation's complex circuit, particularly ground wire is more complicated in the larger situation of electric substation's floor area, and in the bad situation of the light condition such as night, be easy to cause careless omission, this will cause the generation with ground wire combined floodgate accident, so in order to guarantee safety, avoid the generation with ground wire combined floodgate serious accident, be necessary to develop a kind of device of automatic alarm, with the generation of minimizing accident.
Summary of the invention
The objective of the invention is to provide a kind of can be by sound and light alarm before sending electricity, the prompting operating personnel remove ground wire, have easy to operate, and reliable a kind of ground wire acoustic-optic alarm.
Technical characterictic of the present invention is: consider can be under high voltage, high-intensity magnetic field the basis of reliability service be designed to the ground wire acoustic-optic alarm that formed by autoalarm, wireless trigger device, described autoalarm is arranged on the ground wire; Described wireless trigger device and at least one autoalarm form mutual control.
Described autoalarm is a system control device that is made of rectification circuit, automatic power-on circuit, mu balanced circuit, alarm start-up circuit, ring start-up circuit, singlechip controller circuit, control command receiving circuit, speed coupled circuit.
Described autoalarm is the circuit arrangement of energy reliability service under high voltage, high-intensity magnetic field.
Described wireless trigger device is a signal transmission flip flop equipment that matches with autoalarm.
Described wireless trigger device is the control device of wireless of energy reliability service under high voltage, high-intensity magnetic field.
During installation, acoustic-optic alarm of the present invention is installed in the afterbody of existing ground wire, and forms form in parallel with ground wire.When needs carry out service work, can set by the autoalarm time of carrying out, also can information be sent in the autoalarm by wireless trigger device; Autoalarm stores relevant information, and when maintenance closed to an end, autoalarm was sounded and flashing light alarm under the control of circuit, reminds the maintenance personal to remove ground wire; Because service work finishes before the time of setting sometimes, when needs change the time, by wireless trigger device time signal is sent in the autoalarm, thereby can when work finishes in advance, remind operating personnel to remove ground wire.
Advantage of the present invention is: owing to added autoalarm at existing ground wire afterbody, can not forget the dismounting ground wire thereby can automatically sound with the sparkling prompting maintainer when service work finishes; Because autoalarm can move, thereby guaranteed the reliability of equipment under high voltage, high-intensity magnetic field; Because the wireless trigger device can be implemented to autoalarm the control mode of one-to-many, thereby the autoalarm of multiple spot can be triggered simultaneously, can effectively remind the operation maintainer to remove all ground wires; Since wireless trigger device can be under high voltage, high-intensity magnetic field reliability service, so avoided magnetic interference, guaranteed the reliability of trigger; Since easy to install, need not existing ground wire is transformed, reduced workload, so very large practical and popularizing value is arranged.
