Abstract
The present invention provides a kind of method for effectively measuring cyanide content in dry-type power transformer combustion product.This method is using electron tubes type combustion furnace in high-temp combustion dry-type power transformer sample, and ultraviolet-uisible spectrophotometer is tested and analyzed at wavelength 600nm, after dry-type power transformer sample is sufficiently burned, substantially increases the accuracy of test result.
Description
Technical field
The present invention relates to a kind of detection methods of cyanide content in effectively measurement dry-type power transformer combustion product, belong to
The poisonous and harmful substance detection technique field in electronic and electrical equipment.
Background technique
Cyanide refers in particular to the compound with cyano (CN), has severe toxicity, they are widely present in nature, the work of the mankind
It is dynamic to also result in its generation, therefore can the mankind and environment will cause with very big pollution and injury.With the development of technology, dry type electricity
Power transformer has been widely used in industrial circle and daily life, and fire prevention and fire resistance just become its important examination and refer to
Mark.Wherein cyanide present in dry-type power transformer material is the important next of the generation cyanide toxic gas in burning
Source.Therefore transformer needs, high mechanical strength good with dielectric strength, the corrosivity and toxic and harmful gas content that when burning generates
Material few as far as possible.
Content for whether there is toxic cyanide and cyanide in dry-type power transformer combustion product is how many, needs
A kind of convenience, effective detection method detect.
Summary of the invention
Need to detect the content of cyanide in combustion product for dry-type power transformer, the present invention, which provides one kind, to be had
The method for imitating cyanide content in quantitative detection dry-type power transformer combustion product.
The present invention includes a kind of using the test dry-type power change of electron tubes type combustion furnace combination ultraviolet-visible spectrophotometer
The effective ways of cyanide content in depressor combustion product.
Specific embodiment
Below with reference to specific embodiment, the present invention is described in further detail, it is described be explanation of the invention and
It is not to limit.Those skilled in the art can be understood easily advantages of the present invention and effect by the revealed content of specification.This
Invention can also be embodied or practiced by other different specific examples, and the various details in this specification also can be based on difference
Viewpoint and application.
0.1~1g sample is weighed at room temperature in quartz combustion ware, is accurate to ± 0.1mg, and electron tubes type is set
The working procedure of combustion furnace, while blank combustion experiment is carried out at identical conditions.It is generated when being absorbed and burnt with absorbing liquid
Color developing agent is added in gas, between colour developing and stable phase are seasonable under corresponding colour temp.Series standard solution is prepared, step is same
Sample develops the color.With ultraviolet-visible spectrophotometer (UV-vis) quantitative analysis, after establishing standard curve, measurement blank,
Sample solution is checked in the concentration of contained cyanide in sample by standard curve according to the absorbance of each sample.
Above-described embodiment is merely illustrative the principle of the present invention and effect, and is not intended to limit the present invention.It is any
Those skilled in the art can reasonably modify above-mentioned implementation under the premise of without prejudice to spirit of that invention and scope
With variation.Therefore, all authority protection scope of the invention, should be using the range of claims as foundation.
Claims (2)
1. the detection method of cyanide content in a kind of effectively measurement dry-type power transformer combustion product, it is characterised in that use
