Description
Technical field
It the utility model relates to " a kind of leakage breaker of temperature and smog control ", is led for household electricity
Domain.
Background technique
Household electricity is a major issue of the whole society, and either personal house or collective building occupy none resident and do not use
Otherwise 220V alternating current can not live, supply electricity to the mankind and bring greatest benefit, and such as proper use of can cannot also make reprisals once in a while people
Class, electric shock accidents have always existed since electricity consumption, get an electric shock for moment, and the method that can most power off fastly is no more than is protected using electric leakage
Device (abbreviation leakage is protected) is protected, though leakage, which is protected, well also has deficiency, it is raw to protect the human hair that will not have both powered off also and can allow and be put out a fire with water for leakage when catching fire
Electric shock accidents causes to injure life.What the fire early period of origination stage emerged at first is smog certainly, next is only the upper of temperature
Rise, such as leakage protect encounter smog or high temperature to power off this be an extraordinary method, not only power-off in time but also energy protection is rescued with water
Electric shock accidents does not occur for the people of fire.
Summary of the invention
In order to solve above-mentioned problem, the utility model solves the technical solution of its technical problem use, and circuit feature is:
It is protected after switch S1 is connected by fiery zero two wires AC:220V alternating current L-N through leakage and is linked into indoor load power circuit across magnet ring B,
Overvoltage crowbar is formed by varistor RV, indoor load power circuit is formed by load resistance R0, by contact switch S2, electricity

At current limliting, pressure stabilizing, filter circuit, power indicating circuit is formed by resistance R5, flashing diode LED, by adjustable resistance RP1, heat
Quick resistance RT, resistance R6, triode Q composition temperature control power-down circuit, by smoke sensor device BE, resistance R7, capacitor C4, two poles
Pipe D5, adjustable resistance RP2, composition smog power-down circuit.
Circuit theory is:
One, fiery zero two wires earth leakage protective, 220V alternating current L-N is protected after switch S1 is connected through leakage and is linked into room across magnet ring B
Interior load power circuit R0, when normal electricity consumption, the electric current on firewire L returns to zero curve N shape after flowing through indoor load power circuit R0
At a circuit, the electric current that this process moderate heat zero two wires L, N pass through in magnet ring B be it is equal, magnet ring does not play mutual inductance,
Leakage protects switch S1 and does not trip.Circuit is such as connected by resistance R1, contact switch S2, indoor firewire L electric current is through resistance R1, contact
Switch S2 crosses magnet ring B and is connected to input terminal zero curve N forming circuit, at this moment by just logical without electric current on the indoor zero curve N of magnet ring
It crosses therefore fiery zero two wires will generate current difference, magnet ring B plays mutual inductance at this time, will generate induction on mutual inductor L2
Voltage and current, by triggering the grid G of controllable silicon SCR after capacitor C1, C2 charging filtering, resistance R2, R3 partial pressure, making its anode A
Directly be connected with cathode K, at this time the electric current on firewire L through the forward conduction of diode D4 flow through controllable silicon SCR to ground wire, again
Unhook coil T to zero curve N forming circuit is flowed through by diode D2 forward conduction, unhook coil T energized action will be connected to leakage
The hook protected on switch S1 is taken off, and leakage is caused to protect because of the test for powering off and solving to complete manually to power off of breaking off relations.This is by artificial side
The principle of method test power-off, really electric shock is to generate electricity when on the indoor firewire protected by leakage by human contact ground
Flowing into ground forming circuit causes leakage to protect power-off in time, and it is same reason with test resistance R1 that human body, which is exactly a resistance, in fact.
Two, temperature protection, current limliting, pressure stabilizing, filter circuit formed by resistance R4, three-terminal voltage-stabilizing 7809, capacitor C5, by resistance
R5, flashing diode LED form power indicating circuit, are made of adjustable resistance RP1, thermistor RT, resistance R6, triode Q
Temperature controls power-down circuit.Its principle is that adjustable resistance RP connects to form partial pressure with thermistor RT and conventional, electric-resistance R6, three poles
The base stage B of pipe Q only 0.3 or so DC voltage at normal temperature, is not turned in high-impedance state between collector C and emitter E, when
Temperature constantly increases when fire occurs for surrounding, and thermistor RT resistance value reduces when being about raised to 40 degree or so, the base of triode Q
When pole B voltage is increased to 0.7V or more, 9V supply voltage is switched to controllable silicon SCR by conducting between collector C and emitter E
Grid G makes directly to be connected between its anode A and cathode K, and the electric current on firewire L is flowed through through the forward conduction of diode D4 at this time
Controllable silicon SCR flows through unhook coil T to zero curve N forming circuit, unhook coil T to ground wire, again by diode D2 forward conduction
Energized action will be connected to the hook that leakage is protected on switch S1 and take off, causes leakage to protect and power off because breaking off relations, solve because fire incident is made
At human electric shock or property loss problem.
Three, smog is protected, forms current limliting, pressure stabilizing, filter circuit by resistance R4, three-terminal voltage-stabilizing 7809, capacitor C5, by resistance
R5, flashing diode LED form power indicating circuit, by smoke sensor device BE, resistance R7, capacitor C4, diode D5, adjustable electric
It hinders RP2 and forms smog control power-down circuit.Its principle is that the C-terminal of smoke sensor device BE and A terminate positive supply, and lower end D connects adjustable
Its effect of resistance RP2, adjustable resistance RP2 is the size of current of adjustment smoke sensor device BE to reach the height for adjusting sensitivity,
In no external smog the end B do not have voltage, around occur fire have smog close to when, B pole tension is increased to 0.7V gradually
Be added on the base stage B of triode Q when above by the forward conduction of resistance R7, diode D5, make collector C and emitter E it
Between be connected, 9V positive voltage is switched to the grid G of controllable silicon SCR, makes directly to be connected between its anode A and cathode K, this
When firewire L on electric current flow through controllable silicon SCR to ground wire, again by the positive guide of diode D2 through the forward conduction of diode D4
Through-flow to cross unhook coil T to zero curve N forming circuit, unhook coil T energized action will be connected to the hook that leakage is protected on switch S1 and take off
Fall, causes leakage to protect and powered off because breaking off relations, human electric shock or property loss caused by solving the problems, such as because of fire incident, capacitor C4 rise
Filtering is gentle to use use as.
The beneficial effects of the utility model are: adding temperature-control circuit, smog control electricity on existing earth leakage protective device
Road, the smog or high temperature that can reach the initial stage sending because of fire incident detect that environmental hazard promotes leakage to protect fast break
Purpose, ensure that the safety of people's life and property, the beneficial effect is that obviously.
