五、农村安全用电根据历年的统计,全国触电死亡事故85%发生在农村,其中主要是380伏以下的低压触电事故。因此,提高农村用电管理水平,传授安全用电常识,是非常重要和迫切的工作。人为什么会触电?前面我们讲过,导体能够导电,而人体本身就是导体,其电阻值一般在800～1000欧姆之间,当人体接触带电部分,或接触带有不同电位的两点,使人体构成电流回路的一部分便会触电。触电有电击和电伤两种情况。电击多数发生在低压设备上,通过人体内部的电流约在几百毫安以下,能造成体内组织的破坏或功能失调。电伤一般发生在高压设备上,主要是造成人体外部的局部伤害(如电源烧伤),电伤的电流
V. Rural Safety Electricity According to statistics over the years, 85% of the nation’s electric shock deaths occurred in rural areas, mainly low-voltage electric shocks below 380 volts. Therefore, to improve the level of rural electricity management and to teach safety knowledge is a very important and urgent task. Why do people get an electric shock? Earlier, we have said that the conductor can conduct electricity, and the human body itself is a conductor. The resistance is generally between 800 and 1000 ohms. When the human body touches the live part or touches two points with different potentials, A portion of the current loop can cause an electric shock. Electric shock and electric injury in two cases. Most of the electric shock occurs on low-voltage equipment, and the current passing through the human body is below about several hundred milliamps, which can cause the destruction or dysfunction of the body tissue. Electric injury generally occurs in high-voltage equipment, mainly caused by external injuries to the human body (such as power burns), electrical injury
