Description
Technical field
The present invention relates to a kind of support insulator vibroacoustics pick-up unit, particularly a kind of support insulator vibroacoustics pick-up unit with sound and light alarm, and the support insulator vibroacoustics that is applicable to each electric pressure detects.
Background technology
Support insulator in power equipment is as structural support, be in operation due to the impact of environmental baseline and condition of work, constantly be subject to the effect of electric field, cyclic thermal stres, physical shock and environmental attack, its mechanical property can decline gradually with working time, occurred to lose efficacy to cause the risk of accident constantly to rise.The accident that support insulator mechanical failure causes all shows as paroxysmal damage of facilities, conventionally causes huge economic loss, and threatens the stable operation of electrical network.It is the process of a gradual change that support insulator mechanical property declines, and due to the unevenness of pottery and mucilage binding cement structures self, between Different Individual, difference is obvious.If find not in time the variation of support insulator mechanical property, often because mechanical failure causes equipment breakdown.
It is the key that guarantees its safe operation that support insulator has enough physical strengths.Only there is the situation sensitivity of crack defect in conventional support insulator detection means at present for support insulator privileged site, belong to the detection method towards specified defect, can not characterize the defect that support insulator may occur comprehensively, more can not characterize the physical strength of support insulator.In traditional support insulator detection method, supersonic detection method is only effective at the particular case of flange position generation crack defect to detecting support insulator porcelain vase; It is large that ultraviolet detects climate impact, and only effective near the surface crack flange of high-pressure side; Infrared detection, in being subject to weather and solar radiation larger, also lacks corresponding relation between support insulator defect and thermal effect.The problems of mechanical strength that above method all cannot detect because mucilage binding interfacial age gets loose, the aging factor such as break of mucilage binding agent causes, more can not reflect the overall mechanical strength situation of support insulator, the validity of its testing result a little less than.
Due to the fragility of pottery-cement structures itself, do not damaging under the prerequisite of support insulator, cannot directly test its physical strength.Therefore, characterizing its physical strength by detecting the physical quantity directly related with support insulator physical strength, is the unique feasible means of Non-Destructive Testing support insulator physical strength.This type of detection method is ignored the material elements that causes support insulator physical strength to decline, and directly reflects its Strength Changes situation, with respect to the detection means of traditional facing defects, more can directly characterize the health status of support insulator.
At present, the domestic method of having developed for support insulator intensity detection, and develop support insulator vibroacoustics pick-up unit.While utilizing this device to detect support insulator, detection contact is against to insulator flange bottom, the acoustic signal that contact sends is inner through reflection at insulator, and reflected signal passes to computing machine and carries out software analysis processing.Technician, according to reflected signal feature, analyzes intensity and the inherent vice of support insulator.
But existing support insulator vibroacoustics pick-up unit exists the problem of two aspects: 1) testing staff cannot judge whether detection contact is good with contacting of support insulator metal flange, and noise waveform easily appears in loose contact, disturb judgement; 2) detect the data that obtain and be stored in equipment, can not show and consult in time, and can only be at Computer display, delay testing staff and judge in time testing result.
