电动机、电热、电光、电声、电化学及静电等科学技术的不断发展,使电的利用越来越深入到人类活动的各个领域。可以说,电与人类的关系将越来越密切。电,能给人类带来福音,但如果利用不当,它又可给人类造成极大的祸害,甚至危及人的生命。据有关资料的记载,只要有0.1安的极微弱电流流过人体,就能使人的呼吸器官和心脏麻痹,造成触电伤亡事故。再则,由于电器设备维护不善、绝缘损坏或短路等原因引起的火灾,更使国家和个人财产蒙受重大损害。因此,安全用电是每个企业、每个电工、每个家庭,甚至是每个人都得注意的事。但凡有电的地方均有安全用电的问题存在,故本文主要谈谈工矿企业中人们经常接触到的低压配电和
The continuous development of science and technology such as motor, electrothermal, electro-optic, electro-acoustic, electrochemistry and static electricity make the utilization of electricity deepen and deepen into all fields of human activities. It can be said that the relationship between electricity and human beings will become closer and closer. Electricity can bring gospel to human beings, but if used improperly, it can cause great harm to human beings and even endanger human’s life. According to the records of relevant data, as long as a very weak current of 0.1 A flows through the human body, human respiratory organs and the heart can be paralyzed, causing an electric shock casualty. Furthermore, fires caused by improper maintenance of electrical equipment, damaged insulation or short-circuiting, etc., have also greatly damaged the national and personal property. Therefore, the safe use of electricity is something that every business, every electrician, every household, and even everyone must be aware of. Whenever electricity has the problem of safe electricity there, so this article mainly talked about the industrial and mining enterprises in people often come into contact with the low-voltage distribution and
