Abstract
This study investigated the installation status of motors in a rubber product manufacturer’s factory A with high fire load and frequent fires and analyzed the fire. It aims to analyze the electrical and environmental characteristics of the process with the highest fire risk and suggest the fire risk and improvement measures. A total of 15,963 motors are installed and operating in the rubber product manufacturing factory A. We investigated 177 fire accidents that occurred for 19 years from 2002 to 2020 to analyze the installation environment of the motors in the curing and logistics processes, which are major fire risk locations and measure and analyze the temperature and the electrical signals such as current in the load/no-load, locked-rotor conditions due to trouble. The study found no particulars of the current and leakage current under the motor load and no load in the normal motor operating state. However, it confirmed the leakage current rapidly rose to a maximum of 897.8% due to the locked-rotor state in the trouble situation. It also confirmed that the motor temperature exceeded 40℃, the maximum temperature for environmental exposure, in the curing process exposed to a high temperature. The analysis of fires in the site showed the process accounted for the highest proportion of fires. This study is meaningful in that while existing studies were limited to locked-rotor state in the laboratory environment, it proved in an actual industrial site that the current increased more sharply as the motor status approached closer to the locked-rotor state.
期刊介绍：
Interciencia is the monthly multidisciplinary publication of the INTERCIENCIA Association. It is dedicated to stimulate scientific research, its humanitarian use and the study of its social context, specially in Latin America and the Caribbean and to promote communication between the scientific and technological communities of the Americas.
Interciencia has been published uninterruptedly since 1976. Its Founding Director, Marcel Roche (endocrinologist and sociologist of science) was editor until 2008, and thereafter Miguel Laufer (neurobiologist) has been in charge. It has been included since 1978 in the Science Citation Index and other international indexes, and since 2008 it maintains an open access electronic version with material from 2005 onwards.
The priority areas of the journal, without exclusion of other areas, are Agronomy, Arid Lands, Food and Nutrition, Biotechnology, Ecology and Environment, Energy, Innovation and Technology Transfer, Marine Resources, Non-renewable Resources, Science Education, Science Policy, Study and Sociology of Science, and Tropical Forests.
Interciencia publishes in Spanish, Portuguese and English research and review articles, communications and essays, all of which are subjected to peer review. Additionally, it includes non-refereed sections such as Editorial, Letters to the Editor, Open Town Hall, Book Reviews and Upcoming Events.
All the material submitted to the journal for publication and accepted by the Editorial Committee in view of its quality and pertinence is subjected to review by peer specialists in the corresponding fields of knowledge. Neither the INTERCIENCIA Association, nor the journal or the institutions to which the authors belong carry responsibility for the contents. Signing authors are responsible for the material published under their names.
