The working principle and function of circuit breaker in split meter ready board
The circuit breaker is an important protection device in the split meter ready board. Its main function is to protect the circuit and electrical equipment from damage caused by overload, short circuit and other faults. The working principle of circuit breakers is mainly based on thermal magnetic or electronic principles.
working principle:
Thermal magnetic circuit breaker: detects current abnormalities through bimetallic sheets and electromagnets. When the current exceeds the set value, the bimetallic sheet is heated and bent, or the electromagnet generates enough magnetic force to push the switch to open the circuit.
Electronic circuit breakers: Use electronic sensors to detect changes in electrical current. Electronic control circuits trigger the circuit breaker to trip when an overload or short circuit condition is detected.
effect:
Overload protection: When the current exceeds the rated value, the circuit breaker will automatically disconnect the circuit to prevent the wire from overheating and causing a fire.
Short circuit protection: In the event of a short circuit, the circuit breaker quickly disconnects the circuit to prevent equipment damage and fire risk.
Safe operation: The circuit breaker can also be manually operated for daily circuit maintenance and inspection to ensure safety.
In short, circuit breakers play a key protective role in the split meter ready board to ensure the safety and reliability of household and industrial electricity.
