Description
The divisional application that the present invention is the applying date is " on Dec 15th, 2013 ", application number is " 2013106792245 ", name is called the application for a patent for invention of " a kind of insulator contamination sensing device ".
Technical field
The present invention relates to the sensor on a kind of transmission line of electricity, in particular for the filthy sensing device of electric transmission line isolator.
Background technology
Power transmission and transforming equipment insulator surface is easy to the impact by operating area environmental contaminants, so that the pollutant of insulator surface accumulation causes insulation breakdown flashover by the time of tide, insulation flashover then may cause the accident, affect power transmission and transforming equipment reliability of operation, to in the filthy condition evaluation of power transmission and transforming equipment, salt is close be wherein a kind of can be quantitative parameter.For guaranteeing safe and reliable power supply, power department must clean insulator chain by predetermined period, and the close value of the salt of pollutant on insulator arrangement is depended at cleaning period interval.In order to determine the reasonable period of preventive maintenance, ensureing the safe operation of electrical network, the continuous on-line monitoring system of power transmission and transforming equipment insulator salt density should be set up, to implement monitoring to insulation status, avoid the grid pollution flashover accident because environmental pollution causes.
The general pollution severity of insulators thing measuring method adopted is except traditional equivalent salt density method both at home and abroad; the monitoring close to salt also has following methods: (1) pollution layer conductivity method; its advantage be conductivity directly and pollution flashover voltage have relation; the filth of energy concentrated expression pollution layer, but measure comparatively complicated; (2) leakage current method for detecting pollution grade, because the size of leakage current is not only relevant with pollution level, and also relevant with the damp degree of insulator, be only applicable to moist rainy area.
Sensing device based on quartz transducer is also a kind of insulator contamination measurement mechanism used at present.It is theoretical based on the optical field distribution in dielectric optical waveguide and luminous energy loss mechanism that optical sensor is monitored salt close.The multimode dielectric optical waveguide that the low-loss silica rod being placed in air is one is core with rod, air is covering.Time pollution-free on quartz pushrod, by the energy of the basic mode in optical waveguide and higher mode common transport light, wherein most luminous energy transmits in the core of optical waveguide, but has small part luminous energy to be transmitted by the covering along core bag interface, and in light wave transmissions process, the loss of light is very little.When quartz glass bar there being pollution, because pollutant changes the transmission conditions of higher mode and basic mode; Meanwhile, contaminant particles can produce luminous energy loss to the absorption of luminous energy and scattering etc.; By detect luminous energy parameter can calculate sensor surface salinity number.Optical sensor and insulator chain are placed in equivalent environment, by the close value of salt that can be calculated insulator surface.CN2655228Y, CN201016938Y, CN101750262B, CN103234939A and CN103389271A disclose such insulator contamination measurement mechanism.
Owing to being full skirt shape along insulator, the adhesion condition of its distribution of shapes on filth also exists impact.But existing is all annular or circle based on the quartz pushrod in the insulator contamination measurement mechanism of quartz transducer, and namely it only represents that the filth along insulator circumference distributes, as shown in the direction 1 in Fig. 1.But be by full skirt center to full skirt edge direction at insulator arc-over, as shown in the direction 2 in Fig. 1.Therefore, outside along full skirt center filth distribution is more suitable for the pollution level representing insulator.As one aspect of the present invention, provide a kind of insulator contamination sensing device, which provide the filth distribution representing outside along full skirt center.
