Description

A kind of overvoltage protection power receptacle
Technical field
The utility model relates to a kind of socket, specifically a kind of overvoltage protection power receptacle.
Background technology
Electric energy is one of most important energy during people live, and various household electrical appliance all be unable to do without electric energy, and socket is exactly by electricity The electronic equipment that electric energy in net is allocated, socket is electric unit most commonly used in people's daily life and industrial production Part, it can complete line voltage to electrical equipment electric energy join, the most function singleness of existing socket, minority is with guarantor More the socket inside of protective function uses fuse structure, this structure often to use once and will change a fuse, and add Extra spending, and existing socket can only be protected merely, and some people uncomprehending to electricity consumption cannot know concrete power-off Reason, therefore practicality is relatively low.
Utility model content
The purpose of this utility model is to provide a kind of overvoltage protection power receptacle, with asking of solving to propose in above-mentioned background technology Topic.
For achieving the above object, the following technical scheme of the utility model offer:
A kind of overvoltage protection power receptacle, including transformer W, rectifier bridge T, electric capacity C1 and relay K, described transformer One end of the winding N1 of W connects contact K-1 and 220V alternating current, the other end of the winding N1 of transformer W of relay K Connecting socket A and the other end of 220V alternating current, the two ends of the winding N2 of transformer W connect the port of rectifier bridge T respectively The port 3 of 1 and rectifier bridge T, the port 2 of rectifier bridge T connects resistance R1 and electric capacity C1, and the other end of resistance R1 connects Electric capacity C2, the negative electrode of diode D1 and relay K, the other end of relay K connects the control pole of unidirectional thyristor Q1, The other end of electric capacity C1 connects electric capacity C2, the anode of diode D1, LED H, the emitter stage of triode V1 and rectifier bridge The port 4 of T, the anode of unidirectional thyristor Q1 connects the negative electrode of power supply VCC, unidirectional thyristor Q1 and connects resistance R2 and three The emitter stage of pole pipe V2, the base stage of the other end connecting triode V1 of resistance R2 and the other end of electric capacity C3, electric capacity C3 are even The colelctor electrode of the other end connecting triode V2 of connecting resistance R3, resistance R3 and the other end of LED H.
As preferred version of the present utility model: described relay J is normally-closed contact relay.
Compared with prior art, the beneficial effects of the utility model are: the utility model overvoltage protection power receptacle simple in construction, Components and parts are few, not only have the function that overvoltage disconnects automatically, but also utilize light emitting diode and oscillator composition flash of light instruction Lamp, it is possible to can automatically recover after conveniently judging overvoltage condition, and overvoltage disappearance, therefore there is easy to use, diverse in function Advantage with low cost.
Accompanying drawing explanation
Fig. 1 is the circuit diagram of overvoltage protection power receptacle.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out clearly Chu, it is fully described by, it is clear that described embodiment is only a part of embodiment of the utility model rather than whole Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under making creative work premise The every other embodiment obtained, broadly falls into the scope of the utility model protection.
Refer to Fig. 1, a kind of overvoltage protection power receptacle, including transformer W, rectifier bridge T, electric capacity C1 and relay K, One end of the winding N1 of described transformer W connects contact K-1 and 220V alternating current, the winding of transformer W of relay K The other end of N1 connects socket A and the other end of 220V alternating current, and the two ends of the winding N2 of transformer W connect rectification respectively The port 1 of bridge T and the port 3 of rectifier bridge T, the port 2 of rectifier bridge T connects resistance R1 and electric capacity C1, resistance R1's The other end connects electric capacity C2, the negative electrode of diode D1 and relay K, and the other end of relay K connects unidirectional thyristor Q1 Control pole, the other end of electric capacity C1 connects electric capacity C2, the anode of diode D1, LED H, the transmitting of triode V1 The port 4 of pole and rectifier bridge T, the anode of unidirectional thyristor Q1 connects the negative electrode of power supply VCC, unidirectional thyristor Q1 and connects Resistance R2 and the emitter stage of triode V2, the base stage of the other end connecting triode V1 of resistance R2 and electric capacity C3, electric capacity The other end of C3 connects colelctor electrode and the other end of LED H of the other end connecting triode V2 of resistance R3, resistance R3.
Relay J is normally-closed contact relay.
Operation principle of the present utility model is: under normal circumstances, by the voltage of transformer W, rectifier bridge T and resistance R1 not Being enough to turn-on relay K makes unidirectional thyristor Q1 turn on, and therefore the normally-closed contact K-1 of relay K is in closure state, Socket A obtains electric normal work, when there being line voltage to exceed overvoltage critical value (such as 270V), be depressured by transformer W, The voltage of rectifier bridge T rectification and resistance R1 makes the control pole of unidirectional thyristor Q1 turn on again after being enough to turn-on relay K, The normally-closed contact K-1 of relay K disconnects, the load on protection power receptacle A, and unidirectional thyristor Q1 is triggered conducting, The feedback oscillator being made up of triode V1, V2 promotes LED lamp to send passage of scintillation light, prompting electric wire electric leakage.As long as crossing Pressure situation is persistently carried out, then circuit remains at above-mentioned state, and after overpressure situation disappears, circuit recovers automatically, relay The contact K-1 adhesive of K, socket electrifying electricity.
