Direct Current Circuit Breaker
DC Circuit Breaker is a device used in DC power distributed system to prevent circuit from overcurrent and any other potential hazards.
Principle of DC Circuit Breaker
DC Circuit Breaker works on the following principle
- When the current exceeds a rated value, thermal protection trips the breaker and the circuit breaks.
- There is a bimetallic strip heats up and then expands.
- With increase in current, the metallic strip expands.
- This can assist current overload situation. Magnetic protection in DC circuit breakers trips the breaker when many fault current is present.
- This helps to prevent short circuits and other failures.
DC Circuit
Direct Current Circuit or DC Circuit is a closed electrical circuit in which the flow of electricity is in one direction. DC Circuit has a DC Power Supply which produces Direct Current in the circuit. As opposed to alternating current, Direct Current has a fixed magnitude and flows in one direction only. Direct Current Circuit forms a major backbone of the electronics industry.
In this article, we will learn what is Direct Current Circuit, its types, the derivation of voltage and current in different types of DC Circuits, application of DC Circuits, and how to convert AC to DC Circuits.
