摘　　要：穿心式电流互感器是电工器件里一种常见设备,具有连接线路方式简单的特点,被得到广泛应用,同时具有可变性,容易产生计量错误,随着穿心匝数不同穿心式电流互感器电流会发生一定的变化,其电流控制多变,如在穿心式电流互感器使用中所承载负荷较大,技术人员可以通过对穿心匝数进行改变的方式,实现现场对电流互感控制,对整个系统电流比进行调整。因此文章就对穿心式电流互感器的安装使用注意要点进行探讨与分析。Piercing current transformer is a common equipment in electrical devices. It is widely used because of its simple way of connecting lines. It is also variable and prone to measurement errors. With the different number of turns through the current through the core type of current transformer will change, its current control is changeable, such as in the use of the current transformer carrying a large load, technical personnel can change the number of turns through the core in the way. The control of current mutual inductance is realized by adjusting the current ratio of the whole system. Therefore, this paper discusses and analyzes the key points for attention in the installation and use of piercing current transformrs.
