전기 접속부에서의 화재 위험성 연구

Abstract

In recent years, along with the increase in the use of electrical energy, the number of electrical disasters tends to increase. An electrical connection exists to use the electrical energy where it is needed, and the contact resistance increases at the electrical connection, causing electrical heat generation. Electric fires are caused by such electrical heat generation. In this paper, we evaluated the fire risk of electrical connection finish treatment methods. It has been confirmed that the twist connection by the finish treatment method of the electrical connection causes a relatively high temperature rise, resulting in a high risk of fire. When a dedicated connection terminal was used for the electrical connection, the temperature rise occurred in a limited manner, and the temperature change to the extent that it led to a fire did not occur. Therefore, in order to prevent fires from occurring at the electrical connections that inevitably occur, it is judged that fires can be minimized by using dedicated connection terminals.
