Abstract
The invention discloses a quasi-distributed insulator pollution flashover monitoring device comprising a magnetic induction ring, a fixed support, a shell and a magnetic firing pin. The magnetic firing pin is arranged in a slide rail and is slidably coordinated with the slide rail. A sleeve ring is arranged on one end of the magnetic firing pin, and a signal fiber penetrates through the sleeve ring. An optical cable is connected with a far-end test unit. When pollution flashover occurs, the magnetic firing pin in the device is absorbed by the magnetic induction ring and slides so that the signal fiber bends and thus bending loss is generated. The monitoring device in a machine room can detect the position of generation of bending loss on the signal fiber and a corresponding pole tower so that maintainers can go straightly to the position to repair, and thus working efficiency is greatly enhanced and labor intensity is mitigated.
Description
Technical field
The present invention relates to a kind of fibre-optical sensing device, relate to specifically a kind of fibre-optical sensing device of transmission line malfunction monitoring.
Background technology
Electric power is the basis of industry-by-industry, also become one of energy that resident is indispensable, along with the development of domestic economy, the total length of transmission line of electricity and electric power carry span also in continuous increase, but China is with a vast territory, geographical conditions are complicated, also increasing because of thunderbolt, dense fog, the filthy two transmission line of electricity trip accidents that cause, insulator contamination is one of recurrent major accident of transmission line of electricity, causes huge loss to economy.When occurring must to find out fault electricity processing in time after pollution flashover fault, prevent from causing larger power outage.The patent of Chinese Patent Application No. 201020242577.0 has disclosed a kind of scheme, adopt magnetic induction principle, when occurring after pollution flashover fault, this fault detector shows that by fault colored ribbon launches, thereby make fault inspection personnel pole-climbing confirmation abort situation again, improved work efficiency, alleviated labour intensity.But this device still needs tour personnel to search along transmission line of electricity, when transmission line of electricity is long, position is when remote, cannot determine the particular location of fault, still needs to make an inspection tour one by one each power tower bar, its work efficiency is not still very high.
Summary of the invention
Technical matters to be solved by this invention is for above-mentioned deficiency of the prior art, a kind of quasi-distributed insulator contamination monitoring device is provided, adopt quasi-distributed optical fiber sensing technology, just can determine the position of pollution flashover or the numbering of electric force pole tower occur at the machine room of far-end, fault eliminating personnel only need head direct for this position or this shaft tower just can go to have fixed a breakdown.It is simple in structure, lightweight, and cost is low, is suitable for extensive use.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
A kind of quasi-distributed insulator contamination monitoring device, comprise magnetic induction ring 3, fixed support 11, shell 2, magnetic firing pin 4, it is characterized in that: magnetic firing pin 4 be positioned at slide rail 9 and with slide rail 9 be to be slidably matched, one end of magnetic firing pin 4 is mounted with the collar 7, in optical cable 1, include signal optical fibre 6, the part outer jacket that is positioned at the optical cable 1 of housing 2 is peelled off, expose a segment signal optical fiber 6, signal optical fibre 6 is through the collar 7, two ends of optical cable 1 are separately fixed in shell 2 by stationary fixture 10, and optical cable 1 is connected with the test cell 5 of far-end.
In housing, have container 8, a part for signal optical fibre 6 is in the interior coiling of container 8.
Described test cell 5 is optical time domain reflectometer or light source-light power meter.
Described test cell 5 is connected to below processes alarm unit 12.
The present invention compared with prior art has the following advantages:
1, it is simple in structure, cost is low, on optical cable, can be connected in series multiple apparatus of the present invention, thereby forms quasi-distributed insulator contamination monitoring system.
2, maintenance cost is low, after monitoring device moves, after resetting, still can use, and is suitable for the long-term use in field.
3, when occurring after pollution flashover, magnetic firing pin in this device is slided by the attraction of magnetic induction ring, signal optical fibre is occurred bending, from causing bending loss, just can detect that at the monitoring device of machine room the position of bending loss and corresponding shaft tower appear in signal optical fibre, maintainer head direct for the maintenance of this position, thereby greatly improved work efficiency, alleviated labour intensity.
In sum, the quasi-distributed insulator contamination monitoring device of the present invention has simple in structure, lightweight, and cost is low, can increase work efficiency, and reduces labour intensity.
Below by drawings and Examples, technical scheme of the present invention is described in further detail.

Embodiment
Embodiment
The quasi-distributed insulator contamination monitoring device of one as shown in Figure 1 and Figure 2, comprise magnetic induction ring 3, fixed support 11, shell 2, magnetic firing pin 4, magnetic firing pin 4 be positioned at slide rail 9 and with slide rail 9 be to be slidably matched, one end of magnetic firing pin 4 is mounted with the collar 7, in optical cable 1, include signal optical fibre 6, the part outer jacket that is positioned at the optical cable 1 of housing 2 is peelled off, expose a segment signal optical fiber 6, signal optical fibre 6 is through the collar 7, two ends of optical cable 1 are separately fixed in shell 2 by stationary fixture 10, and optical cable 1 is connected with the test cell 5 of far-end.Preferably, described test cell 5 is connected to below and processes alarm unit 12.Multiple devices of the present invention can be installed on optical cable 1, thereby form the system of quasi-distributed monitoring.Its course of work is: when occurring after pollution flashover, magnetic firing pin 4 in this device is slided by the attraction of magnetic induction ring 3, signal optical fibre 6 is occurred bending, from causing bending loss, just can detect that at the test cell 5 of machine room the position of bending loss and corresponding shaft tower appear in signal optical fibre 6, maintainer head direct for the maintenance of this position, thereby greatly improved work efficiency, alleviated labour intensity.
Preferably, have container 8 in housing 2, a part for signal optical fibre 6 is in the interior coiling of container 8.In the time that magnetic firing pin 4 moves, signal optical fibre 6 bendings, the part signal optical fiber 6 being coiled in container 8 can move to outside container 8, and compensating signal optical fiber 6 is positioned at the collar 7 places due to the bending inadequate problem of signal optical fibre 6 length occurring.Prevent signal optical fibre 6 to cause the fault of pulling or breaking to occur.
