发展智能化低压电气设备前景展望

Prospects for the development of intelligent low-voltage electrical equipment

低压电器智能化首先是数字化,数字化是智能化的基础;其次是智能化,主要包括保护算法、控制策略等。目前传统的断路器的四段保护已经非常成熟,而新的断路器的智能化加入了主回路温度监控、触头磨损监控等保护方法。本文对低压电气设备智能化发展进行探讨,以供参考。

The low-voltage apparatus intellectualization has been divided into two parts.One is the intellectualization of low-voltage electrical components.Firstly,digitization is the basis of intelligence,which is the first step to realize intelligence.Secondly,it is intelligent,which mainly including protection algorithm and control strategy.At present,the traditional four-section protection of circuit breaker has been very mature.Now,the intelligent of new circuit breaker has been added with protection methods such as temperature monitoring of main circuit and contact wear monitoring.Based on this,the intelligent development of low-voltage electrical equipment has been discussed below for reference.
