Abstract:

The magnetic release is the key component of DC circuit breaker,which directly determines the short circuit protection performance of DC circuit breaker.The magnetic release based on saturation magnetic circuit is modeled and simulated to obtain the magnetic curve of different currents,and the characteristics of the magnetic release based on saturation magnetic circuit are compared with the traditional single magnetic circuit magnetic release.The results prove that the magnetic release based on saturation magnetic circuit has higher release accuracy and operation reliability,which provides a basis for the design and optimization of magnetic release.

Key words: DC circuit breaker, magnetic release, saturation magnetic circuit, simulation study
