Novel leakage protection socket

Abstract

The invention discloses a novel electric leakage protection socket which is characterized by comprising an analog leakage current generation switch which is in linkage with a reset button. The novel electric leakage protection socket consists of three elastic sheet metals which are arranged in a triangular shape; one of the sheet metals is arranged on the bottom, one sheet metal is arranged in the middle, and the other sheet metal is arranged on the top: the lower sheet metal is connected with a power supply zero line which runs through a differential differentiating transformer by a current limiting resistor; the middle sheet metal is connected with a live wire of a power supply input end by a trip coil; the upper sheet metal is connected with the power supply zero line by a thyristor. The power supply input end of the electric leakage protection socket is connected with the power wire in the wall, and the middle sheet metal is in contact and conducted with the lower sheet metal to form a loop which can automatically generate analog leakage current without operations on any components to generate the analog leakage current; when the reset button is reset, the middle sheet metal tilts up under the elastic action thereof, and is disconnected from the lower sheet metal and in contact and conducted with the upper sheet metal, and the analog leakage current fades away.

Description

technical field [0001] The invention relates to a new leakage protection socket, especially a device that can automatically detect the end of life of the leakage protection socket and display the detection result without operating any parts after the power input end of the leakage protection socket is connected to the power line in the wall A new type of leakage protection socket; the leakage protection socket also has the function of preventing lightning strikes and the function of preventing reverse wiring errors. 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 ea...

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.
