The schematic embodiments of the present invention and their descriptions are used to explain the present invention, and do not constitute improper limitations to the present invention. In the attached picture:

具体实施方式detailed description

为了进一步说明本发明实施例提供的大气腐蚀挂片的耐腐蚀速率测定方法,下面结合说明书附图进行详细描述。In order to further illustrate the method for measuring the corrosion resistance rate of atmospheric corrosion coupons provided in the embodiments of the present invention, the detailed description will be described below in conjunction with the accompanying drawings.

请参阅图1,本发明实施例提供的大气腐蚀挂片的耐腐蚀速率测定方法包括:Please refer to Fig. 1, the method for measuring the corrosion resistance rate of the atmospheric corrosion coupon provided by the embodiment of the present invention comprises:

第一步,获取电网输电线所经过的各个电网输电区域的大气污染物信息;The first step is to obtain the air pollutant information of each grid transmission area that the grid transmission line passes through;

第二步,根据大气污染物信息中主体污染物种类,将各个电网输电区域进行分类,得到N类电网输电区域,N为大于1的整数;In the second step, according to the types of main pollutants in the air pollutant information, each grid transmission area is classified to obtain N-type grid transmission areas, where N is an integer greater than 1;

第三步,从每类电网输电区域中选出任意一个电网输电区域作为测试站点,在该电网输电区域进行输电线路杆塔的大气暴露试验;The third step is to select any grid transmission area from each type of grid transmission area as the test site, and conduct the atmospheric exposure test of the transmission line tower in the grid transmission area;

在大气暴露试验过程中,监测输电线路杆塔上设置的大气腐蚀挂片的腐蚀情况,得到大气腐蚀挂片的耐腐蚀速率。During the atmospheric exposure test, the corrosion of the atmospheric corrosion coupons set on the transmission line towers is monitored to obtain the corrosion resistance rate of the atmospheric corrosion coupons.

通过上述大气腐蚀挂片的耐腐蚀速率测定方法可以看出,由于获取了电网输电线所经过的各个电网输电区域的大气污染物信息,这样就可以根据大气污染物信息中主体污染物种类,将各个电网输电区域进行分类,得到N类电网输电区域,因此,如果需要使输电线路杆塔在不同环境的区域进行大气暴露试验,只需要从每类电网输电区域中选出任意一个电网输电区域,在该电网输电区域进行输电线路杆塔的大气暴露试验即可,而无需在电网输电线所经过的每个电网输电区域都进行输电线路杆塔的大气暴露试验,可见,本发明提供的大气腐蚀挂片的耐腐蚀速率测定方法能够减少输电线路杆进行大气暴露试验的测试站点的数量,从而降低人力物力的投资,缩短不同环境下进行大气暴露试验时,输电线路杆塔上所设置的大气腐蚀挂片的大气腐蚀速率时间。It can be seen from the above method of measuring the corrosion resistance rate of atmospheric corrosion coupons that since the information on air pollutants in each power transmission area of the power grid through which the power grid transmission lines pass is obtained, it can be calculated according to the main pollutant types in the air pollutant information. Each grid transmission area is classified to obtain N-type grid transmission areas. Therefore, if it is necessary to conduct atmospheric exposure tests on transmission line towers in areas with different environments, it is only necessary to select any grid transmission area from each type of grid transmission area. It is enough to carry out the atmospheric exposure test of the transmission line tower in the transmission area of the power grid, without all carrying out the atmospheric exposure test of the transmission line pole tower in each grid transmission area where the transmission line of the power grid passes. It can be seen that the atmospheric corrosion coupon provided by the present invention The method for measuring the corrosion resistance rate can reduce the number of test sites for the atmospheric exposure test of transmission line poles, thereby reducing the investment in manpower and material resources, and shortening the atmospheric corrosion of the atmospheric corrosion coupons set on the transmission line poles and towers when the atmospheric exposure test is carried out in different environments. Corrosion rate time.

值得注意的是,上述实施例中的N类电网输电区域分别为农村区域、工业城市区域、非工业城市区域、污染源区域中的一种多种。而按照N类电网输电区域所处的地理位置,可以为沿海区域或非沿海区域,且不管是沿海区域还是非沿海区域,均可以包括农村区域、工业城市区域、非工业城市区域和污染源区域。It should be noted that the N types of power grid transmission areas in the above embodiments are one or more of rural areas, industrial urban areas, non-industrial urban areas, and pollution source areas. According to the geographic location of the N-type power grid transmission area, it can be a coastal area or a non-coastal area, and whether it is a coastal area or a non-coastal area, it can include rural areas, industrial urban areas, non-industrial urban areas, and pollution source areas.

而且,沿海地区由于处在海洋边缘,其对应的大气环境为海洋大气,海洋大气是指由于海水的蒸发,形成含有大量盐分气体的大气环境,由于此种气体中盐雾含量较高,对金属有很强的腐蚀作用;许多海滨城市受海洋大气的影响,产生腐蚀现象是非常严重的。Moreover, because coastal areas are at the edge of the ocean, the corresponding atmospheric environment is the marine atmosphere. The marine atmosphere refers to the atmospheric environment containing a large amount of salt gas due to the evaporation of seawater. Due to the high content of salt spray in this gas, it is harmful to metal It has a strong corrosion effect; many coastal cities are affected by the ocean atmosphere, and the corrosion phenomenon is very serious.

另外,不管是沿海地区还是非沿海地区,其中的污染源区域是指能够产生特定污染物的区域,污染源区域可以为一种或多种,例如:火力发电厂所产生的污染物为煤炭燃烧后产物的无机小分子气体,如SO2、H2S、NO2等,化工基地所产生的污染物为气体有机分子、建筑工地所产生的污染物为灰尘。而不管是海洋区域工业城市区域所对应的大气环境为工业大气:工业大气指人们在生产或生活中,排放的气体对大气环境造成了污染,构成了含有多种污染物的大气环境,在这种大气环境下,腐蚀速率变得明显加快。In addition, whether it is a coastal area or a non-coastal area, the pollution source area refers to the area that can produce specific pollutants, and the pollution source area can be one or more. For example, the pollutants produced by thermal power plants are the products of coal combustion. Inorganic small molecule gases, such as SO 2 , H 2 S, NO 2 , etc., the pollutants produced by chemical industry bases are gaseous organic molecules, and the pollutants produced by construction sites are dust. Regardless of whether it is an ocean area, the corresponding atmospheric environment of the industrial city area is the industrial atmosphere: the industrial atmosphere refers to the gas emitted by people during production or life, which pollutes the atmospheric environment and constitutes an atmospheric environment containing various pollutants. In this atmospheric environment, the corrosion rate becomes significantly faster.

而且,在沿海地区或非沿海地区中,不管是工业城市区域,还是非工业城市区域,这些区域均可以为省会城市区域或非省会城市区域,而工业城市区域和非工业城市区域所对应的城市按照其人口规模、发展水平等因素,还可以包括特大城市区域、中等城市区域或小型城市区域,且中大城市区域、中等城市区域或小型城市区域可以基于任意国家和地区的标准进行。Moreover, in coastal areas or non-coastal areas, whether industrial urban areas or non-industrial urban areas, these areas can be provincial capital city areas or non-provincial capital city areas, and the cities corresponding to industrial urban areas and non-industrial urban areas According to its population size, development level and other factors, it can also include mega-urban areas, medium-sized urban areas or small urban areas, and medium-large urban areas, medium-sized urban areas or small urban areas can be based on the standards of any country and region.

需要说明的是,进行输电线路杆塔的大气暴露试验所对应的电网输电区域中,上述实施例中的试验站点设置的数量为5个或6个。It should be noted that, in the transmission area of the power grid corresponding to the atmospheric exposure test of transmission line towers, the number of test stations in the above embodiment is set to 5 or 6.

为了清楚的描述上述实施例提供的大气腐蚀挂片的耐腐蚀速率测定方法,下面以南方电网所管辖的各个电网输电区域为例说明,下述描述仅在说明,并不在于限定;In order to clearly describe the method for measuring the corrosion resistance rate of the atmospheric corrosion coupon provided by the above-mentioned embodiment, the following is an example of each power transmission area under the jurisdiction of the China Southern Power Grid. The following description is only for illustration and not for limitation;

南方电网所管辖的区域包括广东省、云南省、广西省、海南省;对每个省执行上述实施例大气腐蚀挂片的耐腐蚀速率测定方法的第一步至第三步,且第一步中,各个电网输电区域的级别相同,且为县级区域以上。The areas under the jurisdiction of China Southern Power Grid include Guangdong Province, Yunnan Province, Guangxi Province, and Hainan Province; the first step to the third step of the corrosion resistance rate measurement method of the above-mentioned embodiment atmospheric corrosion coupons are carried out for each province, and the first step In , the level of each grid transmission area is the same, and it is above the county level.

广东省是一个城市众多,工业发达的省份,其具有代表性的区域很多,不仅有特大城市、沿海城市、农村地区等,另外,其也是南方电网所辖省份里面杆塔腐蚀很严重的一个省份,因此,以广东省为样本进行上述实施例的大气腐蚀挂片的耐腐蚀速率测定。Guangdong Province is a province with many cities and developed industries. It has many representative areas, not only megacities, coastal cities, rural areas, etc. In addition, it is also a province with severe corrosion of towers in the provinces under the jurisdiction of China Southern Power Grid. Therefore, Guangdong Province was used as a sample to measure the corrosion resistance rate of the atmospheric corrosion coupons in the above embodiments.

根据广东省的地理特征,选取了工业污染城市、东南沿海城市、湿热海洋城市、特大城市、无污染城市(即非工业城市)、南边沿海区域以及两个污染源区域;其中,工业污染城市中试验站点的数量为6个,东南沿海城市中试验站点的数量为6个,湿热海洋城市中试验站点的数量为6个,特大城市中试验站点的数量为6个,无污染城市中试验站点的数量为6个,两个污染源区域中试验站点的总数量为6个。According to the geographical characteristics of Guangdong Province, selected industrially polluted cities, southeast coastal cities, hot and humid ocean cities, megacities, non-polluted cities (i.e. non-industrial cities), southern coastal areas and two pollution source areas; The number of sites is 6, the number of test sites in southeast coastal cities is 6, the number of test sites in humid and hot ocean cities is 6, the number of test sites in megacities is 6, and the number of test sites in pollution-free cities The total number of test sites in the two pollution source areas is 6.

从上述广东省中每类电网输电区域的选择可以看出,对于污染比较大的污染源区域,其中所设的试验站点数量相对较多,这样就可以获取更为准确的数据,以指导实际电网建设。It can be seen from the above-mentioned selection of each type of power grid transmission area in Guangdong Province that for the pollution source areas with relatively large pollution, the number of test stations is relatively large, so that more accurate data can be obtained to guide the actual power grid construction .

在上述实施方式的描述中,具体特征、结构、材料或者特点可以在任何的一个或多个实施例或示例中以合适的方式结合。In the description of the above embodiments, specific features, structures, materials or characteristics may be combined in any one or more embodiments or examples in an appropriate manner.

以上所述,仅为本发明的具体实施方式,但本发明的保护范围并不局限于此,任何熟悉本技术领域的技术人员在本发明揭露的技术范围内,可轻易想到变化或替换,都应涵盖在本发明的保护范围之内。因此,本发明的保护范围应以所述权利要求的保护范围为准。The above is only a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Anyone skilled in the art can easily think of changes or substitutions within the technical scope disclosed in the present invention. Should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be determined by the protection scope of the claims.
