电动机断相保护装置

An Interchangeable Equipment for Protecting Electric Motor from Being Broken

常规的电动机断相保护器采用电流互感器作传感器 ,不同容量和规格的电机要配不同的互感器 ,为解决这一问题 ,采用电平衡原理 ,研制了电平衡型电动机断相保护装置。实践证明 ,本装置适用于各种容量的电机 ,而且抗干扰能力强。

Conventional protectors for electric motor broken use current mutual inductor as sensor,electric motors with different capacities and standards need different mutual inductors.In order to solve the problem,based on electric balance principle,an electric balaning mode equipment for protecting electric motor from being broken is developed.The adaptability of the equipment is very capable and it can resist various inferterence.
