Abstract

The utility model discloses a power failure automatic protective socket, which aims to resolve problems of low safety, poor functions and the like in the prior art. The power failure automatic protective socket comprises an insulating casing, a transformer, an electromagnet, an electrified button and a safety transfer switch, wherein the insulating casing is provided with a power input end and a power output end, the transformer, the electromagnet, the electrified button and the safety transfer switch are connected via conducting circuits, and the electrified button is provided with a return spring. An output end of the transformer is in series connection with an electromagnetic coil via the button. When the safety transfer switch is closed, an input end of the transformer is conducted by the power input end, and the power input end and the power output end are conducted by electromagnetic force after the button is pressed down. When the safety transfer switch is open, the power output end is conducted by the power input end. If power is suddenly interrupted, power supply to the electromagnet is stopped as the transformer is free of input voltage, and simultaneously a power output circuit is cut off when magnetic force of the electromagnet is unavailable, the power failure automatic protective socket is free of output voltage when being supplied with power again after power failure, thereby protecting electric appliances and increasing using safety. Besides, the power failure automatic protective socket has the same function as the existing socket when the safety switch is in an open state, thereby increasing functionality and adaptability of sockets.

Description

Outage is the protection socket automatically
Technical field
The utility model relates to a kind of socket, and especially a kind of outage is the protection socket automatically.
Background technology
Existing socket does not generally possess the function of cutting off the electricity supply automatically after the outage, like this, often forget that because of people turning off appliance switch has an accident after outage when powering once more, occurring in the incident that dormitory building 602 schoolgirl bedrooms, school district, Shanghai Business School Xuhui catch fire on November 14th, 2008 is exactly that so burnt area reaches about 20 square metres.Excessive because of the indoor intensity of a fire, 4 collegegirls unfortunately die instantly from the escape of jumping out of the building of bedroom, the 6th building balcony.Be that this dormitory uses immersion heater to heat up water according to investigations, because went up the dormitory outage evening before yesterday of meeting accident, the student does not pull up latch, and sent a telegram here the next morning, and after immersion heater dryouied water, the foreign material on the bed that ignited caused fire.
The utility model content
In order to overcome above-mentioned defective, the purpose of this utility model is to provide a kind of safe, functional strong outage to protect socket automatically.
In order to achieve the above object, outage of the present utility model protects socket to comprise the insulation shell that is provided with power input and output automatically, also comprise transformer, the electromagnet, the power-on button that is provided with back-moving spring and the safe change over switch that connect by the conducting wire, wherein said transformer output is connected with electromagnet coil by power-on button, safe change over switch closure, power input conducting transformer input, press power-on button, by electromagnet magnetic force turn-on power input and output; Safe change over switch disconnects, the direct turn-on power output of power input.
Particularly, described transformer input one end is communicated with an end of power input and output respectively, the closing end of other end attachment security change over switch, described safe change over switch contact is connected with two-way, one the tunnel connects the power input other end, the power output end other end that another road is connected with safe change over switch open end by the conducting of electromagnet magnetic force.
Further, described transformer output one end and solenoid corresponding with it one end are respectively arranged with the contact, described electromagnet core upper end is provided with insulator, wherein, two contacts are arranged between the insulator of power-on button and electromagnet core upper end, leave the gap between between the contact and contact and the insulator.
Further, another terminal portion of described safe change over switch contact and the other end of power output end are respectively arranged with the contact, described electromagnet core lower end is provided with insulator, wherein, two contacts are disposed on the insulator below of electromagnet core upper end respectively, leave the gap between between the contact and contact and the insulator.
Wherein, be shrapnel contact near described power-on button with away from the contact of electromagnet core lower end insulator end.
Wherein, described power input and/or power output end are two-phase power supply or three phase mains.
Above-mentioned structure; under the state of safety switch closure; power input conducting transformer input; the transformer output obtains voltage, presses power-on button, connects to the output circuit of the transformer of electromagnet power supply; make electromagnet produce magnetic force; the magnetic force that produces is connected the outage circuit of the out-put supply of protection socket automatically, and the electrical appliance of connection obtains power supply, starts working.Also under the effect of electromagnet magnetic force, keep on-state to the interchange switching of the input circuit of the transformer of electromagnet power supply this moment, makes entire circuit reach stable power supply state; If this moment sudden power, the protection socket is because transformer has input voltage does not cause stopping to the electromagnet power supply automatically in the back outage that has a power failure, electromagnet loses magnetic force, because of the contactor of the closed out-put supply of electromagnet magnetic force disconnects simultaneously.This just makes the back outage that has a power failure protect socket to return to the off-position of beginning automatically, thereby electrical equipment is played a protective role, and uses safer; Under the state that safety switch disconnects, identical with the socket effect of prior art, the direct conducting output of power input output voltage, power supply once more after the outage, power output end recovers output voltage, has strengthened the functional and applicability of socket.
