Abstract
The utility model discloses a contaminated insulator monitoring device comprising an insulator. A groove is formed in the insulator; and an optical fiber without an external cladding layer is arranged inside the groove, and is connected with a signal output device and a signal receiving and measuring device. According to the utility model, the exposed optical fiber without the external cladding layer is arranged on the insulator, and dirt also adheres to the optical fiber in use of the insulator, so that the light intensity of the optical fiber is influenced. Therefore, the degree of the insulation dirt adhering to the insulator can be measured by virtue of the variation of the light intensity. Compared with a conventional salt deposit density monitoring method, the device can be used for directly monitoring the contamination condition of the surface of the electrified insulator by virtue of the light intensity and does not influence the insulation property and the creep distance of the insulator.
Description
Technical field
The utility model relates to a kind of insulator contamination monitoring device, belongs to the close monitoring of insulation alite field.
Background technology
The surface of porcelain insulator and glass insulator is the continuous contamination of meeting in operational process, increase along with pollution level, the electricity of insulator surface is led also and constantly increased, and develops into to a certain degree just might cause the pollution flashover phenomenon, and is very harmful to the safe operation of electric system.The electric insulator pollution flashover is one of difficult problem that hinders safe operation of power system.The application of porcelain insulator and glass insulator, fundamentally change prevents the importance of pollution flashover problem in electric system.In order to prevent the generation of pollution flashover phenomenon, now adopt measure such as be coated with, wipe, climb to clear up the insulator surface filth, therefore in time grasp external insulation pollution degree, be the inevitable demand of rationally arranging the insulator surface cleaning work.
The current power transmission line measures that salt is close to mainly contain two kinds of methods, and a kind of is that to utilize insulator leakage current to measure salt close, and another kind is to utilize laser sensing commercial measurement salt close.
The drawback that the close method of leakage current measurement salt exists, inapplicable in DC power transmission line.
The close method shortcoming of laser sensing commercial measurement salt is an optical sensing part cost height, the close device of laser sensing commercial measurement salt is contained on the tower bar in addition, device is not to be in the same electric field environment with charged insulator, and the salt that therefore can not directly measure charged insulator is close.
Summary of the invention
The technical problems to be solved in the utility model is, provide a kind of based on the sensing mode that is installed in insulator surface, make that filthy measurement is direct more, convenient, the field is wider, more can react the insulator contamination monitoring method and the monitoring device thereof of insulator contamination situation, can overcome the deficiencies in the prior art.
The technical solution of the utility model is: be that optical fiber is set on insulator, on optical fiber, connect signal output and signal and receive the survey ratio device, and the optical fiber jacket of skimming, the light intensity that can influence in the optical fiber when utilizing filth to be bonded at optical fiber surface is measured the insulation filth degree that covers on insulator.
Offer groove on insulator, optical fiber covers in groove.
Be connected with wireless launcher on signal receive to be surveyed ratio device, when signal receives when surveying light intensity that ratio device monitors and being lower than setting, wireless launcher sends signal and reports to the police, and realizes on-line monitoring.
One of them or the several insulator that is provided with optical fiber is connected on the insulator chain of existing shaft tower, signal output, signal received survey ratio device and wireless launcher is fixed on the corresponding shaft tower, electric energy is provided by sun power and battery.
The insulator contamination monitoring device, it comprises insulator, offers groove on insulator, is provided with the optical fiber of the surrounding layer of skimming in groove, is connected with signal output apparatus, signal reception survey ratio device on optical fiber.
On reception survey ratio device, be connected with wireless launcher.
The degree of depth of groove is 0.4-0.6mm, and the diameter of optical fiber is 0.8-1.2mm.
Compared with the prior art, the optical fiber that the utility model exposes after on the insulator peeling being set, in the process of using with insulator, nuditing fiber also can cover filth thereupon, will influence the light intensity of optical fiber like this, thus the insulation filth degree that can utilize intensity variations to measure to cover on insulator, the close monitoring method of existing relatively salt, utilize light intensity can directly monitor the filthy situation of charged insulator surface, insulating property and the creep distance to insulator can not exert an influence again.
The energy of this device is provided by battery and sun power, can realize in real time and automatically working.This device is subjected to the influence of weather, environment minimum, and the filthy situation of the charged insulator surface of automatic monitoring is convenient to power department and is in time arranged the insulator contamination cleaning work according to data in real time.
This device also has advantages such as adaptability is strong, cost is low, measurement is accurate simultaneously.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Preferred version is for offering groove on insulator, optical fiber covers in groove, one of them or several insulator that will be provided with optical fiber simultaneously are connected on the insulator chain of existing shaft tower, signal output, signal received survey ratio device and wireless launcher is fixed on the corresponding shaft tower, electric energy is provided by sun power and battery, thereby realizes real-time automatic monitoring.
Concrete implementation step:
As shown in Figure 1
1, offer groove 2 in insulator 1 outside, groove 2 is arranged as the semicircle circuit; Or when initial the making, just form the insulator of band groove 2;
2, will be laid on insulator 1 surface along reserving circuit from the plastic optical fiber 3 that splice tray is drawn, the blended rubber bonding guarantees that optical fiber 3 can not come off in groove 2;
3, the plastic optical fiber surface is handled, the part of skimming surrounding layer, thus can make and can influence light intensity in the optical fiber when filth is bonded at optical fiber surface.
4, ball-eye is linked to each other with insulator, then splice tray is fixed on the ball-eye;
5, will lay the insulator 1 of plastic optical fiber 3 and insulator and the ball-eye on the ball-eye alternative routing, and signal output 4, signal be received survey ratio device 5 and wireless launcher 6 is fixed on the corresponding shaft tower, electric energy is provided by sun power and battery.
Key problem in technology 1: the foundation of insulator surface circuit
