中型化学降阻剂是北京石油化工总厂设计院等单位1974年在引进工程中的化学降阻剂基础上进行研究的成果。北京石油化工总厂,地处风化花岗岩地带,土壤电阻率高,接地问题长期以来没有得到解决,对电力系统电气设备的运行和人身的安全存在很大问题,亦是电力专业急待解决的课题之一。为了解决北京石油化工总厂厂区内的接地问题,并为我国高土壤电阻率地区接地问题的研究提供线索,于1975年以北京石油化工总厂设计院为主,并由水电部科研院、北京电力工业局电力试验所、广西南宁电业公司电力试
The medium-sized chemical resistance-reducing agent is the result of research conducted by the Beijing Petrochemical Corporation Design Institute and other units on the basis of the chemical resistance-reducing agent introduced in the project in 1974. Beijing Petrochemical General Factory, located in a weathered granite zone, has a high soil resistivity, and the grounding problem has not been resolved for a long time. There are serious problems in the operation and personal safety of electrical equipment in power systems, and it is also a problem that electric power professionals urgently need to solve. one. In order to solve the problem of grounding in the plant area of the Beijing Petrochemical Complex and to provide clues for the study of grounding problems in high soil resistivity areas in China, the Beijing Institute of Petroleum and Chemical Engineering Design Institute was mainly established in 1975, and the Ministry of Water Resources and Scientific Research Institutes, Beijing Power Industry Bureau Electric Power Test Institute, Guangxi Nanning Electric Power Company Power Test
