“高压线‘辐射’会导致甲状腺癌吗？”针对近期北京市民反映的上述热点问题，前日，记者随同知名学者沈梦培、冶金环境检测中心、北京电力公司的工作人员对变电站、高压线、胡同里的电线杆等设施的电磁强度进行了检测。检测小组称，结果显示，北京市民的居住环境非常安全，供电设施对人体健康和生态不会产生不良影响。

"wire‘radiation’Can lead to thyroid cancer?"According to the recent Beijing residents reflects the hot issue,The day before yesterday,Along with ShenMengPei reporters well-known scholar/Metallurgical environment test center/Beijing electric power company staff in substation/wire/Hutongs facilities such as pole electromagnetic strength testing.Testing group says,Results show that,Beijing residents living environment very safe,The power supply facilities on human health and ecological won't produce adverse effects.

　　随着城市的迅速扩张和用电量的猛增，高压线、变电站越来越多地出现在居住区周围，以往一些110千伏的变电站，如光华路、蓝靛厂变电站，甚至220千伏的变电站，如西大望变电站，已经被纳入中心城区范围。在新的城市电力规划中，像过去那样把110千伏以上的变电站建在郊区、远离城市居民区的地方的做法已不可能，而由于电力传输的需要，必然也必须在闹市区等负荷密集区内选址建设。

Along with the city's rapid expansion and explosion power consumption,wire/Substation increasingly appeared in the residential area around,In the past some 110 kilovolt transformer substation,If GuangHuaLu/Indigo plant substation,Even 220 kv substation,Such as west big hope substation,Have been incorporated in the center of the urban area.In the new urban electric power planning,Like it used to be more than 110 kv substation built in the suburbs/From the practice of urban residential place would have been impossible,And because the power transmission needs,Inevitable must also be in the downtown area, such as load intensive construction site.

　　而很多人所担心的电磁辐射，主要是指在电力输送与使用过程中，输电线路、变电设备和用电设施的周围，都会存在感应电场与磁场。电场是由电压所产生，电压升高时电场强度会增大，电场强度以千伏/米来表示。磁场是由电流通过导线或电气装置时发生的，当电流增加时磁场强度也会加大。

And a lot of people are worried about electromagnetic radiation,Mainly is refers to in power transmission and use process,Transmission line/The substation equipment and power facilities around,Would have induction electric field and magnetic field.Electric field is produced by the voltage,Voltage rise will increase when the electric field strength,Electric field strength to kv/m to said.The magnetic field is the current through the wire or electrical device to happen,When current with the increase of the intensity of magnetic field will also increase.

　　我们身边的这些电力设施实际会产生多大的电场和磁场？是否符合国家相关标准的安全要求？11月1日，知名学者沈梦培、冶金环境检测小组、北京电力公司的工作人员对变电站、高压线、胡同里的电线杆等设施的电磁强度进行了检测。

Our side of these actual power facilities can produce much electric field and magnetic field?In compliance with the relevant state standard safety requirements?On November 1,,ShenMengPei well-known scholar/Metallurgical environment detects the group/Beijing electric power company staff in substation/wire/Hutongs facilities such as pole electromagnetic strength testing.

　　

【安全标准】 [Safety standards]

　　电场强度需≤4千伏/米 Electric field strength should be acuities 4 kv/m

　　世界卫生组织(WHO)和最权威的国际非电离辐射防护委员会公布的《电磁场曝露限值导则》规定：“输电线路的感应电场”的限值标准是5千伏/米(也称“工频电场”)，“输电线路的感应磁场”的限值标准是100微特斯拉(也称“工频磁场”)。世界卫生组织(WHO)的观点是当前关于“工频电磁场”最权威的结论。在一些国家，该观点还被引用作为法庭证据文件。

The world health organization(who)And the authority of the international commission on non-ionizing radiation protection published[Electromagnetic field exposure limit guideline]provisions:"Transmission line induction electric field"The limitation standard is 5 kv/m(Also called"Power frequency electric field"),"The inductive magnetic field of the transmission lines"The limitation standard is 100 micro tesla(Also called"Power frequency magnetic field").The world health organization(who)Point of view is the current about"Power frequency electromagnetic field"The most authoritative conclusion.In some countries,The view was cited as evidence court documents.

　　我国的标准：在交流输变电设施周围环境工频电场强度小于或等于4千伏/米；交流输变电设施周围环境工频磁场强度小于或等于100微特斯拉。

The standard of our country:In ac power transmission and transformation facilities surrounding environment power frequency electric field strength less than or equal to 4 kv/m;Ac power transmission and transformation facilities surrounding environment power frequency magnetic field strength less than or equal to 100 micro tesla.

　　实验1 变电站 Experiment 1 substation

　　站内外辐射都远低于标准 Standing inside and outside radiation are far below standard

　　实验地点：西城区某110千伏变电站，该变电站负责为一些重要的单位和部门供电，周边建筑物、平房林立。

The experiment site:Xicheng district a 110 kv substations,The substation responsible for some important units and departments of power supply,Surrounding buildings/Bungalows with.

　　实验过程：首先，检测小组将用于实验的场强仪贴在变电站外墙的墙根儿，得到一组数值，然后再分别在离墙根两米远、三米远、四米远、五米远、10米远处得到5组数值。

The experiment process:First of all,Inspection team will be used in the experiment field intensity meter stick in the wall of the exterior wall transformer substation right,Get a set of numerical,Then respectively in two metres away from the wall/Three meters/Four metres/Five meters far/10 meters distant get 5 groups of numerical.

　　为了进一步检测变电站里面的状况，检测小组进入平时很难有人走进的变电站，将场强仪紧贴着变压器外的警戒线放置，距离变压器大约有1米的距离，数值显示，在这么近的距离测到的数据，也远低于国家标准和世卫标准。(具体数据信息见表格)

In order to further testing the condition of substation inside,Inspection team into at ordinary times it is difficult to someone walked into the substation,The field intensity meter cling to transformer outside line placed,Distance transformer is about 1 meter distance,Numerical display,In the distance so close to the measured data,Also far lower than the national standard and the world health standard.(Specific data information see form)

　　实验分析：检测人员告诉记者，通过实际数据可以发现，现场的电场、磁场强度很低，即使贴在墙根儿也远低于国家标准上限数百倍。此外一旦离开一段不长的距离，比如十米，电场和磁场强度就会衰减得非常厉害。而根据相关规定，变电站距其他社会建筑的距离至少要有20米。“我们单位的员工小姜从2006年起就在变电站楼上工作，她怀孕时也一直在这里上班，因为我们都知道，变电站等电力设施不会危害儿童与孕妇的身体健康。”市电力公司相关负责人表示。

Experimental analysis:Detect personnel tell reporter,Through the actual data can be found,Field electric field/Magnetic field strength is very low,Even if the stick in the wall right also far lower than the national standard limit hundreds of times.In addition once left a not long distance,Such as 10 meters,Electric field and magnetic field intensity will decay very much.According to relevant regulations,Substation from other social construction distance should have at least 20 meters."Our unit staff since 2006 version in the transformer substation work upstairs,She is pregnant has also been work here,Because we all know,Transformer substation and so on electric power facilities will not harm to children and pregnant women's physical health."The municipal officials say.

　实验2 配电箱 Experiment 2 distribution box

　　“辐射”远低于规定标准 "radiation"Far below standard

　　实验地点：西城区赵登禹路的大茶叶胡同，胡同口有一个10千伏的落地配电箱，10千伏的高压电从这个配电箱出来就变成了380伏，再经过居民家门口的配电箱就变成了我们生活中常用的220伏生活用电。

The experiment site:Xicheng district ZhaoDengYu road big tea lane,HuTongKou have a 10 kv be born distribution box,10 kv of high tension electricity from the distribution box out becomes a 380 v,Then after residents distribution box door will become our life commonly used 220 v living power.

　　实验过程：检测人员在距离一米远用场强仪测得磁场强度0.512微特，电场强度0.220千伏／米，检测人员表示，这个数据是相当安全的。

The experiment site:South tricyclic grass bridge sunny garden,Here is a near the south three yuan large residential area,About 80 metres west side is 220 kv high voltage line corridor.

　　实验过程：检测人员将场强仪置于高压线正下方，显示出磁场强度0.959微特，电场强度0.383千伏／米。随后，检测人员又将场强仪放在高压线外大约30米处，场强仪显示出磁场强度0.164微特，电场强度0.03千伏／米。

The experiment process:Detect personnel will field intensity meter in high voltage wire below,Show magnetic field intensity 0.959 micro characteristic,Electric field intensity 0.383 kv/m.then,Detect personnel and field intensity meter on the high tension line about 30 meters,Field intensity meter shows that magnetic field intensity 0.164 micro characteristic,Electric field intensity 0.03 kv/m.

　　实验分析：这里连接高压线的铁塔林立，地面基本没有建筑物。有人曾有一说，这是不是因为高压线下辐射太强的原因呢？

Experimental analysis:Here the high tension line connection with tower,Ground basic no buildings.Someone had said,This is not because of high pressure offline radiation too strong reasons for it?

　　北京电力检修分公司的张向东表示，根据《电力设施保护条例》，任何单位和个人在架空电力线路保护区内不得兴建建筑物、构筑物。这是为了保护电力设施，而不是很多人误解的“高压线下存在电磁辐射”。

Beijing electric power maintenance branch ZhangXiangDong said,According to[Regulations on the protection of power facilities],Any unit and individual in the overhead power line protection zones shall not build buildings/structure.This is to protect the power facilities,Not many people misunderstood"High pressure offline exist electromagnetic radiation".
