使用电器设备时,经常遇到为满足电气系统工作需要的接地与接零的问题,在进行安全用电以及电路教学中,也常常接触到接地与接零.那么接地等于接零吗?两者有区别吗?本文就接地与接零作一简单介绍.一、什么是“地”与“零”在电气技术运用中,当一个电器设备和大地保持良好接触时,电流可通过地线向大地作半球形传播,
The use of electrical equipment often encounters the problem of grounding and zeroing to meet the operational needs of the electrical system. In the use of safe electrical power and circuit teaching, it is often exposed to ground and zero. Is the ground equal to zero? Is there a difference? This article gives a brief introduction to grounding and zero-crossing. First, what is “ground” and “zero” in electrical technology applications, when an electrical device and the earth maintain good contact, the current can pass The ground wire makes a hemispherical spread to the earth.
