Abstract
The invention discloses a method for monitoring dirtiness of an insulator. The method comprises the following steps of: arranging an optical fiber on the insulator, connecting the optical fiber with a signal output device and a signal reception measuring and comparing device, removing the external cladding layer from the optical fiber, and determining the insulating dirtiness adhered onto the insulator by a fact that the light intensity in the optical fiber is affected when dirt is adhered to the surface of the optical fiber. According to the method, the insulator is provided with the naked optical fiber of which the skin is peeled off, dirt is adhered to the naked optical fiber in the use of the insulator, and then the light intensity of the optical fiber is affected, so that the insulating dirtiness adhered onto the insulator can be determined by the change of the light intensity. Compared with the existing salt deposit monitoring method, the method has the advantages that the dirtiness condition on the surface of the charged insulator can be directly monitored by light intensity, and the insulating property and the creep distance of the insulator are not affected.
Description
Technical field
The present invention relates to a kind of insulator pollution monitoring method and monitoring device thereof, belong to the insulation close monitoring of 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 the measure such as be coated with, wipe, climb to clear up pollution severity of insulators, therefore in time grasp external insulation pollution degree, be the inevitable demand of reasonable arrangement insulator surface cleaning work.
The current power transmission line measures that salt is close mainly contains 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 that the optical sensing part cost is high, the close device of laser sensing commercial measurement salt is contained on the tower bar in addition, device is not to be in same electric field environment with charged insulating, and the salt that therefore can not directly measure charged insulating is close.
Summary of the invention
The technical problem to be solved in the present invention is, a kind of sensing mode based on being arranged on insulator surface is provided, make pollution measurement more directly, convenient, the field is wider, more can react insulator pollution monitoring method and the monitoring device thereof of insulator contamination situation, can overcome the deficiencies in the prior art.
Technical scheme of the present invention is: the insulator pollution monitoring method, the method is that optical fiber is set on insulator, connect signal output and signal and receive the survey ratio device on optical fiber, and the optical fiber jacket of skimming, the light intensity that can affect in 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 lower than setting, the wireless launcher transmitted signal is reported 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 corresponding shaft tower, electric energy is provided by sun power and battery.
The insulator pollution 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.
Survey on ratio device in reception and 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 present invention's exposed optical fiber after on insulator, peeling being set, in the process of using with insulator, nuditing fiber also can cover filth thereupon, will affect the light intensity of optical fiber like this, thereby can utilize the variation of light intensity to measure the insulation filth degree that covers on insulator, the close monitoring method of relatively existing salt, utilize light intensity can directly monitor the filthy situation of charged insulating sub-surface, can not exert an influence to insulating property and the creep distance of insulator again.
The energy of this device is provided by battery and sun power, can realize in real time and automatically working.The impact of this device climate, environment is minimum, and the filthy situation of automatic monitoring charged insulating sub-surface, be convenient to power department and in time arrange the insulator contamination cleaning work according to data in real time.
This device also has the advantages such as strong adaptability, cost is low, measurement is accurate simultaneously.
