Just a magnetic sucking switch needs to be closed after fault clearance, all the electric appliances on the power utilization circuit can automatically recovery to the normal working state. The utility model has the advantages of simple structure, complete function, high reliability, convenient and safe usage, low manufacture cost, etc.
Description
The utility model is a kind of protection switch device with electric line, relates generally to the protection switch device of electric leakage in the single phase circuit, overcurrent, superpressure.
The current protection switch device that is used for various with electric line mostly is the single electric leakage or the person electric shock that only are directed to electric line, electrical appliance greatly and shields.The protective device of modal civilian circuit is exactly the installation insurance silk; when overcurrent, superpressure fault appear in circuit in the mode of blown fuse; with the electric line outage electrical appliance is protected thereby allow, waits to get rid of the fuse that more renews again behind the fault, make circuit recover operate as normal.The stable-pressure device of common various household electrical appliance mostly exists deficiencies such as complex structure, purposes be single on the market, brings some inconvenience to the user.And existing all kinds of air switch mostly is the mechanical structure of metal or bakelite, and bigger to the operating current requirement of overcurrent, to general family and civilian all not too suitable.
The purpose of this utility model is exactly the single phase circuit protection switch device that a kind of energy of designing in order to overcome all inconvenience in the protective device use in the above-mentioned civilian circuit will be integrated to the defencive function of faults such as electric leakage in the circuit, overcurrent, superpressure.
The utility model is achieved by following technical proposals; total input on Live wires road inserts with resistance; electric capacity; diode; triode; controllable silicon; reed switch; mutual inductor; Magnetic sucking switch; the protection switch device that electric elements such as automatic tripping coil are formed; it is characterized in that decompression capacitor 3 is connected bridge rectifier 5; end between 6; bridge rectifier 4; between 7 ends be connected total input on Magnetic sucking switch 1 and the automatic tripping coil 2 that is attached thereto link to each other; 4 of bridge rectifier; end is connected with the collector electrode of triode 11 between 5; the base stage of triode 11 is connected with biasing resistance 9; 10 and filter capacitor 8; and emitter is connected with boost capacitor 12 with diac 13 and be connected reed switch 19 by resistance 14, extremely links to each other by the control of resistance 15 with controllable silicon 17.The output stage of controllable silicon 17 links to each other through current-limiting resistance 16 mutual inductors 18.Two phase lines of output are also respectively enclosed around two in the above through mutual inductor 18 and reed switch 19 respectively.
Use the utility model, all need not installation insurance silk again with all electrical appliances on the electric line, when the superpressure phenomenon of leaking electricity, causing under personal electric shock, overcurrent, short circuit and the situation of supply voltage, can both promptly cut off total input power supply automatically, to guarantee safety with electric line, electrical appliance and life in various pollutions.And after the fault eliminating,, just can recover whole operate as normal rapidly with all electrical appliances in the electric line as long as Magnetic sucking switch of the present utility model is closed.Have simple in structure, multiple functional, the reliability height, easy to use, safe, characteristics such as cheap.
Accompanying drawing drawing of the present utility model is described as follows:
Accompanying drawing 1 is a circuit diagram of the present utility model.
Below in conjunction with drawings and Examples the utility model is further described: the utility model is a kind of protection switch device that is used for circuit and electrical equipment that is contained in total input of electric line, is by resistance 9,10,14; 15,16, electric capacity 3,8; 12, diode 4,5; 6,7,13; triode 11, controllable silicon 17, Magnetic sucking switch 1; automatic dropout switch 2, reed switch 19, mutual inductor 18 electric elements such as grade are formed.When the Magnetic sucking switch 1 that is connected on input is closed, electric current one road is supplied with each electrical appliance on the electric line, another road is then sent into by rectifier diode 4,5,6 by decompression capacitor 3, the 7 bridge rectifier rectifications of forming, and through the effect of biasing resistance 9,10 up and down, by triode 11, bidirectional trigger diode 13, boost capacitor 12 produces a positive voltage at the E point.When with phenomenons such as the not electric leakage of electric line or electrical appliance, personal electric shock, overcurrent, short circuits and since the phase line of output on mutual inductor around two enclosing, the voltage that E is ordered can not trigger controllable silicon 17 and make its conducting.And when fault such as electric leakage or the person electrics shock took place with electric line or electrical appliance, the induced current of the mutual inductor 18 of flowing through increased, and the feasible electric current of extremely going up by the control that is added in controllable silicon 17 behind the current-limiting resistance 16 is with its triggering and make its conducting.The conducting of controllable silicon 17 makes itself and automatic tripping coil 2 and rectifier diode 7 form a loop, and total input power supply of using electric line is cut off in Magnetic sucking switch 1 action at this moment rapidly, thereby has guaranteed the safety of the electrical appliance and the person.
The phase line of the utility model output is close on the wall of reed switch 19 around two circles, utilizes the magnetic field that electric current produced of this root phase line of flowing through to control the closure of reed switch 19.When with electric line or electrical appliance generation overcurrent, short circuit phenomenon, the electric current of the reed switch 19 of flowing through increases and its closure, the voltage that E order is added on the F point, voltage is delivered to its conducting of triggering in the control extremely of controllable silicon 17 by current-limiting resistance 15.This moment controllable silicon and automatic tripping coil 2, rectifier diode 7 forms a loop, and Magnetic sucking switch 1 move rapidly, cuts off the total input power supply with electric line automatically, thereby has guaranteed with electric line, electrical appliance and personal safety.
When supply voltage is subjected to various pollutions and when causing that voltage surpasses normal electricity consumption scope, through Magnetic sucking switch 1, decompression capacitor 3, bridge rectifier 4,5,6,7 electric current is at filter capacitor 8, biasing resistance 9,10, triode 11, boost capacitor 12 under the effect of bidirectional trigger diode 13, promptly produces a forward high voltage at the E point and makes bidirectional trigger diode 13 conductings, thereby on the F point, produce a positive voltage, be added in by current-limiting resistance 15 in the control extremely of controllable silicon 17 and make its conducting.Controllable silicon 17 and tripping coil 2 so automatically, diode 7 forms a loop, and Magnetic sucking switch is moved rapidly, cuts off total input power supply of using electric line automatically, thereby guarantees that each electrical appliance does not damage because of the power pollution superpressure.
The utility model has been realized the protection with faults such as electric line and the in use contingent electric leakage of electrical appliance, overcurrent, superpressure, person electric shock, short circuits by simple electronic installation; get rid of the back Magnetic sucking switch that only need close when fault, each electrical appliance interior with electric line can recover operate as normal rapidly.Convenient and simple for operation, safety, the reliability height can be used for the various civilian electric line of using, and is particularly suitable for the use of general family, uses more convenient and safety to the people who does not have electrician's knowledge.
