Technical Field
The invention relates to the field of electricity safety, in particular to a short-circuit protection socket with a visual state.
Background
In power utilization accidents, short circuit is the most common power utilization accident, when a circuit is short-circuited, the current in the circuit can be suddenly increased, so that the circuit or an electric appliance is burnt, the household electrical short circuit often occurs in the use process of a socket, when an old household appliance and a new household appliance share the socket, the new household appliance can be damaged due to the influence of the short circuit current when the old household appliance is short-circuited;
the existing socket only has a power supply function, cannot protect short-circuit behaviors, cannot protect other electric appliances on the same socket, and cannot know which socket is out of order very quickly after short circuit occurs, so that the socket cannot be overhauled in time and further loss is possibly caused.
Disclosure of Invention
The invention aims to solve the defects that a line and an electric appliance cannot be protected and a socket with a short circuit used by the electric appliance cannot be quickly and accurately positioned in the prior art, and provides a short-circuit protection socket with a visual state.
In order to achieve the purpose, the invention adopts the following technical scheme:
a state visualization short-circuit protection socket comprises a panel and a wire box, wherein a light transmission strip and a reset switch are installed on the panel, three wire connectors are installed on one side, away from the panel, of the wire box, a first live wire contact, a first zero line contact, a second live wire contact, a second zero line contact and a ground wire contact are installed in the wire box respectively, a double-color indicator lamp is installed in the position, opposite to the light transmission strip, in the wire box, a zero line wiring end and a ground wire wiring end are installed in the wire box respectively, and a short-circuit action mechanism is installed in the wire box;
the short circuit action mechanism comprises a protection box and an action box which are arranged in a line box, an electromagnetic relay is arranged in the protection box and comprises a solenoid, an elastic electric pole, a first contact and a second contact, a rectification voltage stabilizing circuit board is arranged in the action box, two metal sliding sleeves are symmetrically arranged on the rectification voltage stabilizing circuit board, two magnetic conductive plates and two permanent magnetic conductive plates are symmetrically arranged on the rectification voltage stabilizing circuit board and positioned on two sides of the two metal sliding sleeves respectively, and a metal contact rod is inserted in each metal sliding sleeve in a sliding manner;
reset switch, solenoid, elasticity pole, first contact, first live wire contact and second live wire contact establish ties in proper order, first zero line contact, second zero line contact and zero line wiring end establish ties in proper order, ground wire contact electric connection ground wire wiring end, two permanent magnetism current conducting plate electric connection first contact and double-colored pilot lamp, two respectively the magnetic conduction current conducting plate electric connection second contact and double-colored pilot lamp, double-colored pilot lamp electric connection ground wire wiring end.
Preferably, the action box is mounted against the protection box, and the two magnetically conductive plates are close to the solenoid.
The invention has the following beneficial effects:
1. current when short circuit through electromagnetic relay induction line socket circuit, short-circuit current is greater than rated current, make the magnetism reinforcing of solenoid adsorb elasticity pole, make elasticity pole and first contact separation and contact with the second contact, break off the power supply of first live wire contact and second live wire contact promptly, make on first live wire contact and the second live wire contact no electric current pass through, can protect promptly on the socket used with electrical apparatus simultaneously, also can protect the bus circuit not disturbed, increase the security of socket.
2. When the socket is not short-circuited, part of current flows to the permanent magnetic current conducting plate through the first contact, the permanent magnetic current conducting plate is in sliding contact with the permanent magnetic current conducting plate through the magnetic force adsorption metal contact rod, the two metal sliding sleeves are respectively connected with the input and output ends on the rectification voltage stabilizing circuit board, then the current is input into the rectification voltage stabilizing circuit board from the metal sliding sleeves through the permanent magnetic current conducting plate contact metal contact rod, then the direct current is output through the metal sliding sleeves and is transmitted to the double-color indicator lamp through the metal contact rod and the permanent magnetic current conducting plate, so that the double-color indicator lamp is green, during short circuit, the short circuit current is increased, the magnetism of the solenoid is enhanced to adsorb the elastic electric pole, so that the current is enabled to flow to the magnetic current conducting plate along the second contact, the solenoid with enhanced magnetism enables the magnetic current conducting plate to generate larger magnetism, then through metal sliding sleeve, metal feeler lever and magnetic conduction current conducting plate output to double-colored pilot lamp, make it be red, realize the visualization of socket state, the personnel of being convenient for know socket state fast and in time overhaul.
In summary, the invention cuts off the circuits of the first live wire contact and the second live wire contact through the short-circuit protection of the electromagnetic relay, avoids the influence of short circuit on the electrical appliances and the bus circuit which are used simultaneously, increases the safety, changes the input and the output of the rectification voltage stabilizing circuit through the short-circuit protection action of the electromagnetic relay, changes the double-color indicator lamp, and realizes the visualization of the use state of the socket.
