一、概述随着自动化水平的不断提高,世界上大型工厂的电缆敷设数量也越来越多,从几百公里到几千公里,电缆火灾事故也不断增多,损失也越来越大。据全国电力系统1965～1975年不完全统计,发生的50多起电缆火灾事故中,直接损失达1000多万元,间接损失约50亿元。美国1965～1975年电气火灾累计3282次,电缆延燃事故就占了30.5％。西德、日本、瑞士、苏联等国均有多起电缆延燃事故发生;日本一火电厂一次电缆事故就损失3000万美元。我国钢铁企业的电缆延燃事故也在逐年增多,仅在1971～1984年间就发生
I. Overview With the continuous improvement of the level of automation, the number of cable laying in large-scale factories in the world is also increasing. From a few hundred kilometers to several thousand kilometers, the number of cable fire accidents is also increasing, and losses are also increasing. According to the incomplete statistics of the national electric power system from 1965 to 1975, among the more than 50 cable fire accidents that occurred, direct losses amounted to more than 10 million yuan and indirect losses amounted to about 5 billion yuan. The total number of electrical fires in the United States from 1965 to 1975 was 3,282, and cable explosion incidents accounted for 30.5%. In West Germany, Japan, Switzerland, and the Soviet Union, there have been a number of cable delay incidents; a cable accident in a thermal power plant in Japan lost US$30 million. The number of cable-burning accidents in China’s steel companies has also increased year by year. It only occurred between 1971 and 1984.
