Novel electric leakage protection socket

Abstract

The invention discloses a novel electric leakage protection socket, which is characterized in that: input ends of a live wire and a zero line of a power supply are respectively extended with a right-angled triangular point discharge metal sheet used for discharge; and points of the two metal sheets are oppositely arranged and spaced at a certain interval. In a concrete embodiment of the invention,power input connection pieces connected with input metal sheets of the live wire and the zero line of the power supply and input terminal screws of the live wire and the zero line of the power supplyare respectively extended with a point discharge metal sheet for discharge, and points of the two metal sheets are oppositely arranged and spaced at a certain interval. The live wire of the power input end of the electric leakage protection socket is also connected with the zero line at the power input end through a tripping coil and a voltage dependent resistor. The novel electric leakage protection socket can prevent thunder and lightening and the damage caused by high transient voltage due to other causes, and also prevent loads connected with the electric leakage protection socket, namelyhousehold appliances such as refrigerators, color TVs, air conditioners and the like from being stricken by high voltage.

Description

technical field [0001] The invention relates to a novel electric leakage protection socket, in particular to a novel electric leakage protection socket with the lightning protection function. Background technique [0002] With the continuous development of the leakage protection socket industry, people have higher and higher requirements for the safety of the leakage protection socket. It is hoped that during the use of the leakage protection socket, when its life ends, that is, when its internal components fail and lose the leakage protection function, the user can be reminded in time to replace it with a new product. [0003] However, the common earth leakage protection sockets on the market not only do not have the end-of-life detection function, but also do not have any reminder function for the user when their life ends, and the reset button can still be reset, and the load of the earth leakage protection socket The single-phase three-wire power output jack on the surf...

AI Technical Summary

Problems solved by technology

When the installer mistakenly connects the power live wire and neutral wire in the wall to the power output end of the leakage protection socket, the single-phase three-wire power output jack on the surface of the leakage protection socket will have power output, and at this time, the electricity flowing through The current of the equipment does not flow through the leakage protection circuit inside the leakage protection socket at all. Therefore, the leakage protection socket does not play any leakage protection function at this time. If there is leakage, it is very easy to cause the user to be electrocuted.
