Abstract
The utility model discloses a quasi-distributed insulator pollution flashover monitoring device which comprises a magnetic induction ring, a fixing bracket, a shell and a magnetic firing pin, wherein the magnetic firing pin is located in a sliding rail and is in sliding fit with the sliding rail, one end of the magnetic firing pin is equipped with a lantern ring, a signal optical fiber passes through the lantern ring, and an optical cable 1 is connected with a remote test unit. When pollution flashover occurs, the magnetic firing pin of the device slides under the attraction of the magnetic induction ring so as to make the signal optical fiber bent and to cause bending loss, the monitoring device in a computer room can detect the position where the bending loss of the signal optical fiber occurs and a corresponding tower, and maintenance personnel can go straight to the position to carry out maintenance, thereby greatly improving the work efficiency and reducing the labor intensity.
Description
Technical field
The utility model relates to a kind of fibre-optical sensing device, relates to a kind of fibre-optical sensing device of transmission line malfunction monitoring specifically.
Background technology
Electric power is the basis of industry-by-industry, also become one of indispensable energy of resident, development along with 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 tripping operation accidents that cause, insulator contamination is one of recurrent major accident of transmission line of electricity, causes tremendous loss to economy.After the pollution flashover fault takes place, must find out fault electricity and processing in time, prevent from causing bigger power outage.The patent of Chinese patent application numbers 201020242577.0 has disclosed a kind of scheme, adopt magnetic induction principle, when the pollution flashover fault takes place after, this fault detector shows that with fault colored ribbon launches, thereby make fault inspection personnel pole-climbing affirmation abort situation again, improved work efficiency, alleviated labour intensity.But this device still need be maked an inspection tour personnel and search along transmission line of electricity, grows, when the position is remote, can't determine the particular location of fault that when transmission line of electricity still need make an inspection tour each electric power tower bar one by one, its work efficiency still is not very high.
Summary of the invention
Technical problem to be solved in the utility model is at 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 to take place the position of pollution flashover or the numbering of electric force pole tower 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, and is in light weight, and cost is low, is suitable for extensive use.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of quasi-distributed insulator contamination monitoring device, comprise magnetic induction ring 3, fixed support 11, shell 2, magnetic striker 4, it is characterized in that: magnetic striker 4 be positioned at slide rail 9 and with slide rail 9 be to be slidingly matched, one end of magnetic striker 4 is mounted with the collar 7, include signal optical fibre 6 in the optical cable 1, the part outer jacket that is positioned at the optical cable 1 of housing 2 is peelled off, exposed a segment signal optical fiber 6, signal optical fibre 6 passes the collar 7, two ends of optical cable 1 are separately fixed in the shell 2 by stationary fixture 10, and optical cable 1 is connected with the test cell 5 of far-end.
Described test cell 5 is optical time domain reflectometer or light source-light power meter.
Described test cell 5 back are connected to handles alarm unit 12.
The utility model compared with prior art has the following advantages:
1, it is simple in structure, cost is low, can be connected in series a plurality of the utility model devices on optical cable, thereby forms quasi-distributed insulator contamination monitoring system.
2, maintenance cost is low, and monitoring device action takes place by still using after resetting, and is suitable for open-air long-term use.
3, after pollution flashover takes place, magnetic striker in this device is slided by the attraction of magnetic induction ring, it is crooked that signal optical fibre is occurred, from causing bending loss, monitoring device at machine room just can detect position and the corresponding shaft tower that bending loss appears in signal optical fibre, the maintainer head direct for the maintenance of this position, thereby improved work efficiency greatly, alleviated labour intensity.
In sum, the quasi-distributed insulator contamination monitoring device of the utility model has simple in structure, in light weight, and cost is low, can increase work efficiency, and reduces labour intensity.
Below by drawings and Examples, the technical solution of the utility model is described in further detail.

Embodiment
Embodiment
A kind of quasi-distributed insulator contamination monitoring device as shown in Figure 1 and Figure 2, comprise magnetic induction ring 3, fixed support 11, shell 2, magnetic striker 4, magnetic striker 4 be positioned at slide rail 9 and with slide rail 9 be to be slidingly matched, one end of magnetic striker 4 is mounted with the collar 7, include signal optical fibre 6 in the optical cable 1, the part outer jacket that is positioned at the optical cable 1 of housing 2 is peelled off, exposed a segment signal optical fiber 6, signal optical fibre 6 passes the collar 7, two ends of optical cable 1 are separately fixed in the 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 back are connected to and handle alarm unit 12.A plurality of devices of the present utility model can be installed on optical cable 1, thereby form the system of quasi-distributed monitoring.Its course of work is: after pollution flashover takes place, magnetic striker 4 in this device is slided by the attraction of magnetic induction ring 3, it is crooked that signal optical fibre 6 is occurred, from causing bending loss, test cell 5 at machine room just can detect position and the corresponding shaft tower that bending loss appears in signal optical fibre 6, the maintainer head direct for the maintenance of this position, thereby improved work efficiency greatly, alleviated labour intensity.
Preferably, container 8 is arranged in housing 2, the part of signal optical fibre 6 is coiled in container 8.When 4 actions of magnetic striker, signal optical fibre 6 bendings, the part signal optical fiber 6 that then is coiled in the container 8 can move to outside the container 8, and compensating signal optical fiber 6 is positioned at the collar 7 places owing to the crooked not enough problem of signal optical fibre 6 length that occurs.Prevent from causing the fault of pulling or breaking to occur to signal optical fibre 6.
