Description

Technical Field

[0001] This utility model relates to the field of electric shock protection technology, specifically to a power switch with electric shock protection effect. Background Technology

[0002] A residual current device (RCD) is a grounding protection device used to prevent electric shock and accidents caused by leakage current. When the leakage current of a circuit or electrical equipment exceeds the device's setting value, or when a person or animal is at risk of electric shock, it can quickly act to cut off the power supply, prevent the accident from escalating, and ensure the safety of people and equipment. In places with a high risk of electric shock, such as bathrooms, swimming pools, and tunnels, high-sensitivity, fast-acting RCDs should be selected. If a person can be quickly disconnected from the power source in the event of an electric shock, the operating current of the RCD can be greater than the let-go current. If it is a fast-acting protection device, the operating current can be selected based on the ventricular fibrillation current. If it is a front-stage protection, i.e., the main protection before the branch protection, the operating current can exceed the ventricular fibrillation current.

[0003] Ordinary electrical switches have a relatively simple external structure, which is insufficient for overall protection and lacks protection against electric shock. This poses safety hazards to users and fails to meet their needs, thus reducing their practicality. Utility Model Content

Vertical indicator lights near the edge of the top of the main control board display real-time operating statuses such as power on / off and faults (e.g., green light for power on, red light for faults). A voltage detection block near the main control board on the top of the switchboard monitors the circuit voltage in real-time. If the voltage is abnormal (too high or too low), a buzzer near the bottom edge of the top of the switchboard will sound an alarm, and the indicator lights will simultaneously switch to fault indication. The switch group on the top of the switchboard near the voltage detection block connects to external circuits through fixed connectors at its top and bottom slots, enabling control of branch circuits. The openings around the top of the switchboard and the fixed limit block at the center provide limiting and fixing for the switch group and other components, ensuring stable operation. The entire system achieves safe and stable power control functions through the coordinated use of structural encapsulation, core control, status monitoring, and abnormal alarms.
