Problems solved by technology

If there is no burn at the connection of the ground lead wire of the tower, the insulators installed on the cross arm of the tower must be checked one by one within the reference range. It is not easy to find, thus missing the lightning strike tower; when the fault point cannot be found in one inspection, the inspection scope is often expanded, multiple inspections are performed to eliminate the fault, and even the inspection by climbing the tower is a waste of time and manpower, and it is easy to cause safety accidents

Embodiment Construction

[0025] Below in conjunction with embodiment the present invention is described in further detail:

[0026] Insulator fault precise location system, such as figure 1 As shown, it includes a fault location device 1, a signal sending device 2, and a designated receiving device 3 connected to the signal sending device 2 through a wireless network.

[0027] The fault location device 1 is arranged on the cross arm of the pole and tower close to the tested insulator, and is located within a safe distance from the insulator. The input end of the fault location device 1 is electrically connected to the terminal of the insulator; the output end of the fault location device 1 is connected to the input end of the signal sending device 2 .

[0028] The specific structural diagram of the fault location device 1 is as follows: figure 2 , image 3 As shown, it includes a metal casing 11, the metal casing 11 is arranged on the cross arm through the positioning card 16, and the metal casing...

Abstract

The invention discloses a precise positioning system for insulator faults, which is used in the field of transmission line fault monitoring. The system comprises a fault positioning device arranged on a pole and tower cross arm close to a measured insulator, a signal sending device, and an appointed receiving device connected with the signal sending device through wireless network, wherein an input end of the fault positioning device is electrically connected with a wiring end of the insulator, an output end of the fault positioning device is connected with an input end of the signal sending device. The precise positioning system disclosed by the invention is arranged on a conductor cross arm, when the insulator flashes over after being be struck by lightning, the fault positions of the pole and tower struck by lightning and the insulator can be precisely positioned, information is fed back to the working staff in time, the time for troubleshooting the fault positions is reduced, faults are eliminated in time, and the safe operation of an electric grid is guaranteed.

Description

technical field [0001] The invention relates to the field of fault monitoring of power transmission lines, in particular to an accurate positioning and detection device for insulator faults. Background technique [0002] Most of the faults of electrical equipment are insulation faults, especially high-voltage transmission lines. The equipment is exposed to various harsh natural environments and is easily affected by environmental factors such as lightning strikes, pollution, wind deflection, rain, fog, ice and snow, and the insulation is damaged. , leading to the occurrence of ground faults. Because of the suddenness of this kind of accident, the losses caused to the society are far greater than the losses of the equipment itself. [0003] Due to the large length and wide distribution of overhead lines, the probability of being struck by lightning is high, and the resulting accidents are also many. At present, the on-line monitoring methods of the line are not enough, espec...
