OVERCURRENT PROTECTION DEVICE AND CHARGING DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240204505 titled 'OVERCURRENT PROTECTION DEVICE AND CHARGING DEVICE

The abstract describes an overcurrent protection device that includes input and output terminals, a breaker, a current sensor, and a comparator. The device is designed to protect against excessive currents by monitoring and interrupting the flow of electricity when necessary.

The device has a breaker with a switch that opens upon receiving an interrupt command signal, disconnecting the circuit to prevent damage.
A current sensor measures the difference in current between input and output terminals to detect overcurrent situations.
A comparator compares the measurement value from the current sensor to a predetermined threshold value and triggers the interrupt command signal to the breaker if the current exceeds the threshold.
The device is designed to provide efficient and reliable protection against overcurrent situations in electrical circuits.
By promptly interrupting the flow of electricity when necessary, the device helps prevent damage to equipment and ensures safety in electrical systems.

Potential Applications: - Industrial machinery - Electrical distribution systems - Renewable energy systems

Problems Solved: - Prevents damage to equipment from overcurrent situations - Enhances safety in electrical systems

Benefits: - Reliable overcurrent protection - Prevents costly damage to equipment - Ensures safety in electrical systems

What are the key benefits of using an overcurrent protection device in industrial machinery? Using an overcurrent protection device can prevent damage to equipment, ensure safety in electrical systems, and reduce maintenance costs for businesses.

Original Abstract Submitted

an overcurrent protection device includes a first input terminal, a second input terminal, a first output terminal, a second output terminal, a breaker, a current sensor, and a comparator. a positive terminal and a negative terminal of a power source are connected to the first input terminal and the second input terminal. the second output terminal is connected to the second input terminal. the breaker includes a switch connected between the first input terminal and the first output terminal and opening upon reception of an interrupt command signal. the current sensor measures a difference between a current flowing between the first input terminal and the first output terminal, and a current flowing between the second input terminal and the second output terminal. the comparator sends the interrupt command signal to the breaker when a measurement value of the current sensor exceeds a first current threshold value.
