Abstract
The utility model relates to an automatic circuit breaking and warning plug for the electrical leakage, which belongs to an emergency protector for basic electric elements, belongs to a triplex receptacle outlet of the power cord of household appliances, and is used for the electrical leakage protection of the household appliances. Signal receiving circuits comprises two specially applied integrated circuits, an LED used for replacing an AC mutual inductor, and a photodiode. The power supply can be cut off and the utility model can continuouslygive out the sound until the restoring at the outer housing leakage or at the error sequence connection of the zero conductor and the live conductor of the electrical outlet.
Description
The utility model relates to the emergency protective device in the essential electronic element.The earth leakage protective that is used for household electrical appliance.
Existing market is sold the leakage-current alarm plug that uses, and principle is fairly simple, and volume is also very little, basic principle such as Fig. 2
Be placed on slotting Xiao of power input line of electrical appliance.A point earth connection, B point connecting to neutral line.Work as electrical leakage, zero, when ground wire voltage surpasses safe voltage 36V, its piezoelectric patches just sends audible alarm.Its weak point is, when electrical leakage, only reports to the police and do not cut off the power supply, and to some users that do not understand alarm effect child particularly, do not have protective effect especially.If when using socket, do not note with B point insertion live wire seat, will be artificial make 220V voltage on the shell band, become the electric shock accidents source on the contrary.In addition, all the user is used as a this principle design alarm of passage, has only user's contact electrification body, the link tester Leader is alert, and is just very dangerous from the principle.As present most leakage alarm; application number is 90217280.8 an integrated circuit safety utilizations of electric power economize on electricity comprehensive protection device; application number is 90213762.X power protector, also all application integrated circuit or controllable silicon, but to get the electric leakage signal circuit all be the D.C mutual-inductor of using for it.Cause the alarm volume big like this, the cost height.
Mirror gives the present situation that present alarm uses, and the utility model guarantees to use the personal safety of household electrical appliance from this angle of safety utilization of electric power.The electric leakage instant alarming takes place, and will cut off the electricity supply, preferably volume is little, and cost is low, and is easy to use, all has in the supply line of every household electrical appliance.
The utility model is to realize by following circuit structure, by light-emitting diode, photodiode, resistance, pin 4 be with 555 integrated circuits that pin 7 is associated in, and is connected on the music integrated circuit between circuit anode and the pin 4 and the bidirectional triode thyristor that is connected on the live wire is formed the leakage-current alarm deenergizing circuit.By neon lamp; photodiode, resistance, 555 integrated circuits that pin 4 is associated in pin 7; the bidirectional triode thyristor composition that is connected on the music integrated circuit between circuit anode and the pin 4 and is connected on the live wire is distinguished zero live wire circuit and overvoltage crowbar automatically, and mutual group is dressed up a three-wire system attaching plug.Finish the earth leakage protective when the household electrical appliance leakage-current alarm is cut off the electricity supply and the generation of attaching plug wrong plug connector socket is artificial leaks electricity.
Be described further below in conjunction with line map of the present utility model.
