Solar Power Electrical Devices Function Introduction

DC circuit breaker mainly has the following functions:

Function

Description

Interrupt Direct Current

Designed to safely interrupt direct current (DC) flow in electrical circuits to protect against overloads and short circuits.

Arc Suppression

Utilizes various mechanisms such as magnetic fields and auxiliary capacitors to suppress arcs generated during the breaking process.

Bidirectional Fault Current Interruption

Capable of interrupting fault currents in both directions, ensuring comprehensive protection in DC transmission lines.

Magnetic Field Application

Applies a magnetic field to the vicinity of the arc to control and extinguish it quickly, enhancing performance.

Simplified Structure

Incorporates filtering and surge-absorbing capacitors to simplify the overall structure and improve efficiency.

Self-Excited Commutation

Uses self-excited commutation techniques to enhance the speed and reliability of current interruption.
