由机械工业部抗震研究室负责承担的“高压电器减震技术研究”课题,经过三年多的工作,现已全部通过了鉴定。课题提出的高压电器抗震计算程序、抗震试验方法已得到了较广泛的应用,课题研制的几种减震体系已安装在电力工程现场,进行试运行。该课题的研究成果,直接为我部生产的高压、超高压电器产品服务,为提高其抗震能力做出了贡献。我国现有的高压、超高压电器产品、过去不进行抗震计算,而大部分又缺乏必要的抗震能力,经不起强震的袭击。一九七六年唐山地震,致使该地区所有变电站、输电线路不能受电运行,并严重波及京津地区、使京、津,唐电网大面积停电。强震引起的停电、停水,不仅严重影响抗震救灾工作的进行,而且直接威胁灾区人民的生命和财产,造成了严重的社会和经济后果。
The “Research on High-Voltage Electric Apparatus Damping Technology” undertaken by the Seismic Research Office of the Ministry of Machinery Industry has passed all the tests after more than three years of work. The seismic calculation program and seismic test method for high-voltage electrical appliances proposed by the project have been widely applied. Several shock-absorbing systems developed by the project have been installed at the electric power engineering site for trial operation. The research results of this topic directly serve the high-voltage and ultra-high-voltage electrical products produced by our department, and have contributed to the improvement of its anti-seismic capability. China’s existing high-voltage, ultra-high voltage electrical products, in the past did not perform seismic calculations, but most of them lack the necessary anti-seismic capabilities, can not stand strong attacks. The Tangshan earthquake in 1976 caused all substations and transmission lines in the region to be inaccessible to electricity and seriously affected the Beijing-Tianjin region and caused extensive power outages in Beijing, Tianjin and Tangshan power grids. The power cuts and water cuts caused by strong earthquakes not only seriously affect the work of the earthquake relief work, but also directly threaten the lives and property of the people in the disaster areas, causing serious social and economic consequences.
