Electric leakage and overcurrent protection socket

Abstract

The invention discloses a leakage and overcurrent protection socket, which includes a leakage induction coil for sensing whether there is leakage of a single wire to the ground, and a tripping relay for controlling the on-off of the circuit. When the leakage of the single wire to the ground occurs, the circuit control system controls the The tripping relay is disconnected, cutting off the power supply. Real-time detection of the circuit by setting leakage induction coil, current mutual induction coil and voltage transformer to realize instant power-off protection. The risk of electric shock is reduced because the socket is disconnected when it is not normally used and the tripping relay is manually opened and then energized only during normal use. Eliminate the danger of leakage: When the human body touches the single live wire, it is necessary to manually open the tripping relay to get an electric shock, but the circuit control system will automatically cut off the power to prevent electric shock. Prevent fires caused by overcurrent. Energy saving and environmental protection, prolonging the service life of the circuit control system.

Description

technical field [0001] The invention belongs to the field of electrical and electronic technology, and in particular relates to a leakage and overcurrent protection socket. Background technique [0002] Socket is the insertable seat that one or more circuit connections are arranged, can insert various wiring by it, is convenient to connect with other circuits. Through the connection and disconnection between the line and the copper parts, the final connection and disconnection of the part of the circuit is achieved. [0003] Leakage protection socket is suitable for occasions prone to leakage, overcurrent and short circuit, especially for high-end electrical sockets. If the cost factor is not considered, it is also a high-end substitute for ordinary sockets. D&Z series leakage protection sockets and overcurrent protection sockets adopt modular structure, humanized design, compact structure, beautiful appearance, safety and reliability, long service life and easy installat...

AI Technical Summary

Problems solved by technology

[0004] At present, the leakage protection socket on the market is to disconnect the electricity when it detects that the live wire and the ground have a circuit, so that the problem that arises is that when the live wire and the neutral wire pass through the human body at the same time, there will be a danger of electric shock; fire hazard
