Description

Automatic power alarm socket leaks electricity

The utility model relates to the automatic power alarm socket of a kind of electric leakage, belongs to dynamo-electric interconnecting devices.

The suitable conductor that certain resistance is arranged of on record human body, when the alternating current of 220 volts of 50Hz flow through human body with 0.001-0.01A, the people just had the fiber crops pain, if surpassing 30MA is that 0.03A people will be hit unconsciously, lose the ability of breaking away from power supply, break away from measure, just be in peril of one's life as nothing; Because of the electrical appliance electric leakage causes the electrical equipment internal short-circuit to cause the countless of fire, have many people to invent a variety of earth leakage protective sockets and earth leakage protective device in recent years, but because of function is incomplete, the time of cutting off the electricity supply is long, safe and reliable inadequately, unsatisfactory.

For overcoming above-mentioned harm because of leaking electricity the person being caused; overcome the deficiency of existing earth leakage protective device and electric leakage socket; it is a kind of multiple functional that the purpose of this utility model has been a research and design; the discovery leaky can be cut off the electricity supply at once; refusal has the use of the electrical equipment of leaky to it, is exactly 0.001 second electric leakage process, and socket also will be controlled automatically; sound, light are reported to the police simultaneously again, protect the safety of the person and property with this.

The purpose of this utility model provides the automatic power alarm socket of a kind of electric leakage, and its technical scheme is: this socket with power connection after, when the electrical equipment 3-phase plug of no leaky, when inserting this socket, green indicating lamp is luminous, expression power supply output is normal; Electrical equipment in no leaky in use cuts off the power supply sound, light warning simultaneously at once just in case this socket of leaky occurs.As the electrical equipment 3-phase plug of leaky, when inserting this socket, automatic system and green indicating lamp are closed at once automatically, cut off socket power simultaneously, red led is luminous, and louver sends sound equipment and carries out sound, light warning, when pulling up the plug of Electrical leakage, automatic system quits work; Its operation principle is: when electric leakage appears in electrical appliance; leakage current just feeds back to the earth connection jack by it self ground protection line; after the rectification diode is made halfwave rectifier; through the dropping resistor step-down; carry out filtering and charging by electrochemical capacitor; make automatic system obtain a dc pulse voltage; make the actuating of relay; with normally closed fixed contact A; N disconnects; at A; N cuts and N; the moment relay of B closure will lose voltage; at this moment discharge by electrolytic capacitor; assist to relay; make it finish above action; work as N; after the B closure; Light-Emitting Diode constitutes the loop and luminous warning with automatic partly loop contact after the dropping resistor step-down; work as N; after A disconnects; rectifier diode will lose voltage; but because of N; the B conducting; just make power firestreak N after rectifier diode carries out halfwave rectifier; enter dropping resistor; finish above-mentioned course of action, double base diode and piezoelectric ceramics sheet produce the higher-order of oscillation simultaneously, and the pronunciation of piezoelectric ceramics sheet is reported to the police; adjust resistance and can change the frequency of oscillation that oscillator swings device; because of rectifier diode is the individual event breakover element, as the reverse withstand voltage 700V of IN4007, backward resistance is very big; so the electric current after rectifies can't feed back to the earth connection jack; refuse the electric leakage of electrical appliance shell with this, when pulling up the plug of electric leakage electrical equipment, zero line L jack and automatic system loop contact disconnect; the operating voltage loop of automatic system is cut off; relay discharges, fixed contact A and moving contact N conducting again, and it is normal that socket recovers.

The utility model major advantage that automatic power alarm socket compares with other socket of leaking electricity is: the electrical equipment 3-phase plug of no leaky, and green indicating lamp is luminous when inserting this, and the indication power supply is switched on, and also indication partly enters readiness automatically simultaneously; If leaky appears in the electrical appliance that makes, automatically partly close the out-put supply of socket automatically, green light extinguishes, red led and alarm start warning simultaneously, and its advantage is that refusal has the electrical equipment of leaky and the 3-phase plug of equipment thereof to insert this socket, has accomplished to prevent trouble before it happens, this socket manufacture technology is simple, with low cost, the coefficient of safety height is easily applied.
