民用建筑电动机保护控制设计探讨

Discussion on Motor Protection Control Design of Civil Building

通过分析民用建筑中电动机及其主回路保护与控制元件的主要特性,对电动机的保护控制设计进行探讨,并对“断路器-接触器-热继电器”电动机保护控制方案进行案例说明,给出设计选型过程。

The motor protection control design is discussed by analyzing the main characteristics of the protection and control elements on the motor and its main circuit in the civil building,the motor protection control scheme of“circuit breaker⁃contactor⁃thermal relay”is described,and the process of type selection for design is presented.
