摘　　要：本文论述了保护接地、保护接零的原理和使用范围，对每种保护措施，详细地计算了流经人体的电流。指出了不同的电网，必须使用适合该电网的保护措施。否则，就会造成触电事故。本文目的在于引起实验室工作人员的足够重视，合理地运用保护措施。其次，为研究开发先进的保护设备提供一些数据。The essay clarifies the principle and using rang about protecting ground and protecting zero. It also calculates the electric current form human body to ground for two kinds of measurements and point out that we must adopt corresponding protecting measurements so as to adapt the different electricity network. Otherwise the shock would be occurred. The essays purpose is that causes the stuffs enough attention and use protecting measurements reasonably. Next providing some date for developing advanced security equipments.
