The fast dust density measuring device can reduce the filter time of dirty solution, thereby accelerating the dust density measurement on external insulation pollution of power equipment, to reduce the dirty solution filtration from several hours to several minutes, to realize fast, effective and accurate dust density measurement on the external insulation pollution of power equipment, reduce measurement time significantly and improve working efficiency.
Description
Technical field
The utility model belongs to a kind of measurement mechanism, relates to the close measurement mechanism of a kind of quick ash of field of electrical equipment specifically.
Background technology
The external insulation design of present China's working line and power station equipment is to be based upon on the basis of the principle of cleaning in a year one and dirty differentiation Butut to adopt creepage ratio to carry out apart from method.In recent years pollution flashover accident repeatedly shows, although be carried out in accordance with regulations to transfer to climb pollution flashover takes place still, and close with 1 year crude salt serve as that the basis is determined gradation for surface pollution, disposed the generation that external insulation can not have been stopped the large tracts of land pollution flashover by creepage ratio apart from method.New result of study shows, the close zone of close, the different ash of different salt may be in same dirty district, correspondingly chooses identical external insulation configuration; The close different ashes of identical salt are close may to be in different dirty districts, and the external insulation of choosing is widely different." dirty level and the external insulation choice criteria distinguished of Q/GDW152-2006 electric system " provided the new argument that the electrical network gradation for surface pollution is divided, promptly with saturated equivalent salt density and the close definite gradation for surface pollution of ash, reasonable disposition external insulation level can effectively prevent the generation of pollution flashover on this basis.
During close measurements of ash, need filter, water-fast filth is filtered out filthy solution, through then oven dry, weigh, link such as calculating, finally obtain grey close value.Present filthy solution filters and all adopts gravity natural filtration method to filter, and the resistance that the natural gravity of dependence water overcomes filter paper filters.This method filter velocity is slow, and particularly under the denseer situation of soiling solution concentration, the general heavy soiling solution filtration time of 300ml was wanted more than 5 hours.Cause grey close measuring period long like this, poor operability, measuring accuracy also are subjected to various artificial factor easily.
Summary of the invention
Goal of the invention: the purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of quick ash close measurement mechanism, it can shorten filthy solution filtration time, accelerate the grey close measuring speed in the power equipment external insulation pollution, thereby measure the close value of power equipment external insulation pollution ash fast, efficiently and accurately.
Technical scheme: the technical solution adopted in the utility model is: the close measurement mechanism of a kind of quick ash, and it comprises accelerator, filtering flask and funnel; Accelerator is connected with filtering flask by measuring channel, and funnel is connected with filtering flask.
Accelerator comprises power supply, single-chip microcomputer, vacuum pump, negative pressure adjustment module and pressure vacuum gauge, power supply is connected with vacuum pump with single-chip microcomputer respectively, single-chip microcomputer is connected with vacuum pump by the negative pressure adjustment module, and pressure vacuum gauge is installed on the measuring channel that is communicated with vacuum pump and filtering flask.
Wherein, described funnel is a Buchner filter.
Beneficial effect: the utility model can shorten the filtration time of filthy solution, thereby accelerate the grey close measuring speed in the power equipment external insulation pollution, making originally wanted the filthy solution filter process of a few hours to shorten in a few minutes and can finish, thereby fast, measure the close value of power equipment external insulation pollution ash efficiently and accurately, greatly shorten Measuring Time, improved work efficiency.
Description of drawings
Be illustrated as structural representation of the present utility model.
Embodiment
Below in conjunction with description of drawings embodiment of the present utility model.
The close measurement mechanism of quick ash as shown in the figure, it comprises accelerator 1, filtering flask 2 and funnel 3; Accelerator 1 comprises power supply 11, single-chip microcomputer 12, vacuum pump 13, negative pressure adjustment module 14 and pressure vacuum gauge 15.Power supply 11 is connected with vacuum pump 13 with single-chip microcomputer 12 respectively, and power supply 11 provides working power for single-chip microcomputer 12 and vacuum pump 13.Single-chip microcomputer 12 is connected with vacuum pump 13 by negative pressure adjustment module 14, the speed that single-chip microcomputer 12 control negative pressure adjustment modules 14 are regulated vacuum pump 13.Pressure vacuum gauge 15 is installed on the measuring channel that is communicated with vacuum pump 13 and filtering flask 2, the vacuum tightness that pressure vacuum gauge 15 is used for showing filtering flask 2 and connects gas circuit.The vacuum pump 13 of accelerator 1 links together by measuring channel and filtering flask 2, and 2 are connected on the funnel 3 by rubber stopper on the filtering flask.
To select diameter for use be the 8mm rubber tube to measuring channel in the present embodiment, and power supply 11 provides the working power of DC12V for single-chip microcomputer 12 provides the working power of DC5V for vacuum pump 13.Single-chip microcomputer 12 can be selected W78E58B for use, and negative pressure adjustment module 14 adopts adjustable potentiometer, and vacuum pump 13 is selected the VAA5008 model, and pressure vacuum gauge 15 is selected the P-V25DS-010B model for use.
During the close measurement of ash, on funnel 3, place filter paper, filthy solution is poured in the funnel 3, start vacuum pump 13 by control accelerator 1, vacuum pump 13 extracts in the filtering flasks air in 2, makes that space and the space outerpaces in the filtering flask 2 produce negative pressure, because external pressure is higher than the air pressure inside of filtering flask 2, force moisture to flow through filter paper fast, reach and quicken the purpose that filthy solution filters.Regulate negative pressure adjustment module 14 rotating speed of step-less adjustment control vacuum pump 13 as required, thereby regulate vacuum magnitude, the low more filter velocity of negative pressure is just fast more.
The utility model provides the thinking and the method for the close measurement mechanism of a kind of quick ash; the method and the approach of this technical scheme of specific implementation are a lot; the above only is a preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle, can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.The all available prior art of each component part not clear and definite in the present embodiment is realized.
