Description

Technical Field

[0001] The utility model relates to the technical field of low-voltage electrical appliance manufacturing, in particular to an intelligent circuit breaker. Background Art

[0002] A circuit breaker is an electrical device that automatically cuts off power in the event of an overload or short circuit. The ubiquitous power Internet of Things (IoT) connects, monitors, integrates, and analyzes data from users and devices across power generation, transmission, transformation, distribution, and consumption, serving all power-related nodes and enabling integrated data collection and application. Temperature sensors can monitor the temperature rise of circuit breakers, meeting the need for the "three-in-one" integration of energy, business, and data.

[0003] Most temperature probes currently on the market are installed directly into holes in the base and secured with thermal adhesive. This method is complex and results in significant distance errors between the temperature probe and the connection plate, affecting measurement accuracy. The temperature probe is connected to the circuit breaker controller via a flexible cable, which is complex to install within the circuit breaker's wire duct and can easily escape from the duct, causing wire breakage. Current circuit breaker voltage sampling systems are also connected to the controller via a flexible cable, which can easily escape from the duct, causing wire breakage and, in severe cases, short circuits. Summary of the Invention

By mounting the temperature sensor on the circuit board, the installation process is simplified and the sensor's installation accuracy is guaranteed.
