Abstract

Basing on a moveable power supply socket configuring with a leakage automatic switch, the utility model increases technology contents that a varistor is connected in series between the input terminal of the phase wire of a leakage automatic switch and the output terminal of a zero wire; the wire of the output terminal of the phase wire of the leakage automatic switch is wound on a dry reed tube, both ends of contacts of the dry reed tube are respectively connected with the output terminal of the phase wire of the leakage automatic switch and a checking circuit, and therefore, the utility model has the functions of leakage, overvoltage, lightning, and over current protections.

Description

Mobile power socket

The utility model relates to a kind of mobile power socket.

Occurred disposing the mobile power socket of automatic switch of electric leakage on the market, but at other improper situation that may occur in the electric process, above-mentioned mobile power socket obviously also lacks comprehensive defencive function.

The purpose of this utility model provides a kind of mobile power socket that possesses more defencive function.

Solution of the present utility model is that phase line at automatic switch of electric leakage is arranged under the improper situation the just electric component of conducting between with zero line.

Illustrate particular content of the present utility model below in conjunction with drawings and Examples.

Accompanying drawing is circuit theory diagrams of the present utility model.

As shown in the figure, the utility model is to be arranged under the improper situation the just electric component of conducting on the basis of the mobile power socket that has disposed automatic switch of electric leakage K between the phase line of automatic switch of electric leakage K is with zero line.Described electric component has piezo-resistance R ₁With tongue tube P, specific embodiments is as follows: one, piezo-resistance R ₁Two ends go out to hold E to be connected with the phase line inlet side M of automatic switch of electric leakage K with zero line respectively.Two, the two ends of tongue tube P go out to hold N to be connected with testing circuit S with the phase line of automatic switch of electric leakage K respectively, and automatic switch of electric leakage K phase line goes out to hold the lead L coiling of N to be on the reed pipe P that these two embodiments can be implemented one by one, also can merge enforcement.In addition, in the phase line of automatic switch of electric leakage K and the inlet side of zero line, phase line is played the effect that an overhand knot Q also can play anti-thunder and lightning with zero line.

Above-mentioned solution one is to have increased over-voltage protection function on earth leakage protective basis, its principle is when voltage surpasses the permission amplification of rated voltage, the rapid conducting of piezo-resistance causes the current imbalance on phase line and the zero line, makes full electric automatic switch action power dump; Lightning induction in fact also is a kind of overvoltage phenomenon, so this scheme has lightning protection electric work energy simultaneously.Scheme two is to increase excess current protective function on earth leakage protective basis; its principle is the situation in overcurrent; cause the current imbalance of phase line and zero line by the conducting of tongue tube; and then cut off the electricity supply; if scheme one and scheme two are combined; so, this mobile power socket has the defencive function of electric leakage, overvoltage, thunder and lightning and overcurrent simultaneously.
