Abstract

The invention relates to a power transmission and distribution line pre-warning system, in particular to a high-voltage line operation external force prevention pre-warning method which is realized through the following steps that a laser transmitting end, a laser alarm control host and a global system for mobile communication (GSM) wireless network transceiver are fixedly arranged on an iron tower on one end of a high-voltage line to be monitored; the laser rays from the laser transmitting end are in alignment with positions of 5m, 6m and 8.5m blow the sag of a power transmission line between two towers; a corresponding laser receiving end is arranged on the iron tower on the other end of the high-voltage line and corresponds to the laser transmitting end, so that the transmitted laser rays can be received; and the high-voltage line operation external force prevention pre-warning method has the beneficial effects that the theft of pole towers or the error touch of other external force can be prevented to the largest extent, and a pre-warning effect is achieved immediately.

Description

The external force method for early warning is put in a kind of high-tension line operation
Technical field
The present invention relates to a kind of electric line early warning system, particularly the external force method for early warning is put in a kind of high-tension line operation.
Background technology
The faults such as ground connection, overcurrent, quick-break usually occur in power circuit owing to reasons such as weather, equipment and outside destroy at present, cause the power failure in some areas, and cause certain loss to the client; Distribute in addition wide, distance, ageing equipment, the factor such as with a varied topography along the line are also so that circuit is searched relatively difficulty after breaking down.In addition, because the tower material of ultra-high-tension power transmission line is stolen than being easier to, cause mad robber of some lawless persons to be cut, this has had a strong impact on safe and stable operation and the normal electricity consumption order that supplies of electrical network, and the casualty accident that often causes getting an electric shock occurs, and at present, camera monitoring system has been laid in area with good conditionsi, play preferably anti-theft effect, but still had the high problem of installation and operation cost.
Summary of the invention
Purpose of the present invention is exactly in view of the foregoing defects the prior art has, provide a kind of high-tension line operation to put the external force method for early warning, can prevent to greatest extent that the generation of the stolen phenomenon of shaft tower or the mistake of other external force from bumping phenomenon, and play the early warning effect in the very first time.
Technical scheme of the present invention is to be realized by following methods:
(a) the high-tension line one end steel tower in the needs monitoring has installed and fixed Laser emission end, laser warning main control system and GSM wireless network acceptance emission all-in-one, lower 5 meters, 6 meters, 8.5 meters positions of power transmission line sag between laser beam horizontal aligument two towers of Laser emission end; Other end steel tower at high-tension line is installed corresponding laser receiving terminal, and is corresponding with the Laser emission end, and the laser beam of emission can be received;
(b) system enters duty when managerial personnel or Control Room are deployed troops on garrison duty instruction to the laser warning main control system by mobile phone or computing machine after, in case 5 meters of object proximity hi-lines occur, 6 meters, 8.5 trigger alarm during the warning distance value of rice, the voice suggestion that on-the-spot loudspeaker sends audio alarm " Keep Clear-High Voltage; take care ", main frame is simultaneously with warning message, comprise the tower name, the position, the risk distance value, accept the emission all-in-one by the GSM wireless network and send to the related management personnel, managerial personnel can directly carry out the long-range prompting of propagandaing directed to communicate, or realize the networking disposal with electric power 110;
Above-mentioned steel tower is provided with video monitoring system, transmits online on-the-spot realtime graphic, video by wireless 3G/GPRS/WCDMA wireless network to Surveillance center.
The invention has the beneficial effects as follows: utilize the changing value of laser detection hi-line magnetic field intensity and laser to come and go the positional distance that the object transmission required time is determined outer object and hi-line, carry out pre-alarm according to predefined what safe distance parameter value, automatically propaganda directed to communicate by scene high sound loudspeaker alarm prompting, remote alarms, long-range caution when surmounting basic warning value or other preset value, directly stop at the scene the superelevation object to the destruction of hi-line, or carry out consistency operation by dispatch center and dispose; , apart from computational analysis the arboreal growth state under the hi-line is monitored for a long time according to relative position, realized the superelevation warning; Can prevent to greatest extent that the generation of the stolen phenomenon of shaft tower or the mistake of other external force from bumping phenomenon, and play the early warning effect in the very first time.
