一种低压配电柜
By linking smoke and temperature alarms in the low-voltage distribution cabinet to control the electromagnet to cut off power, and combining mechanical transmission with simple electrical control logic, the linkage between automatic power cut-off and fire extinguishing components is realized. This solves the problems of power interruption delay and low reliability in existing technologies, and improves safety and stability.

AI Technical Summary
Existing low-voltage distribution cabinets require manual power-off after detecting a danger signal, which results in a time delay. Furthermore, the automatic power-off function relies on complex software programs or multiple independent modules, leading to high equipment costs, difficult maintenance, and low reliability.
The system employs a smoke alarm and a temperature alarm to control the electromagnet to cut off power. Automatic power-off is achieved through a sliding rod and a micro-control switch. Combining mechanical transmission with simple electrical control logic, and equipped with fire extinguishing and shielding components, it achieves integrated safety protection of alarm, power-off, and fire extinguishing.
It enables rapid power cut-off in the early stages of an accident, preventing the fire from spreading, reducing the risk of equipment damage and personal injury, improving the reliability and stability of safety protection, and reducing maintenance difficulty and cost.
