Abstract
The utility model relates to an overvoltage self-strip safety combined socket. Self-strip switches are connected in series between an input socket and electric wires of an output socket. After trip coils are connected with a silicon controlled rectifier in series, the trip coils are connected in parallel between the electric wires of an output socket. After a control electrode of the silicon controlled rectifier is connected with current limiting resistor and voltage dependent resistor, the control electrode of the silicon controlled rectifier is connected with one end of a trip coil. The utility model integrates switches of an electric source and an overvoltage protective function into one body, switches off an output electric source and a self electric source. The utility model has the advantages of reliable work and advanced performance.
Description
The utility model relates to a kind of emergency protective device in the electricity field, particularly a kind of safeguard protection socket.
Existing overvoltage protection switch and socket, generally self long-term charged work is met overvoltage and can not be thrown off, and reaction speed is slow, and is ineffective to the power consumption equipment protection.Chinese patent 93238982.1 provides a kind of " lightning protection, anti-overvoltage safety socket switch "; only all be connected in parallel on load, power consumption equipment and overvoltage protector on the mains supply; thereby the long-term charged work of this socket, can not throw off voluntarily, not thorough to equipment protection.
The purpose of the utility model aims to provide a kind of superpressure throws off voluntarily, when having mains switch effect, superpressure, and the not charged work of socket, protection speed is fast, the superpressure self-falling-off type security combination socket of function admirable.
Technical solution of the present utility model is: be in series with the autospasy switch between two electric power connection lines of this superpressure self-falling-off type security combination its input plug of socket and accessory power outlet, secondary connection accessory power outlet two power lines of autospasy switch, tripping coil is with after controllable silicon is connected, two ends are parallel between accessory power outlet two power lines, are connected to tripping coil one end after the silicon controlled control utmost point seals in current-limiting resistance and piezo-resistance.
The utility model is compared with prior art; the autospasy switch is thrown off under the superpressure situation; disconnect power consumption equipment power supply and self socket power and working power; reaction speed is fast; protection is reliable; the utility model consumed power not under the guard state particularly; conduction time≤0.1 of guard mode second; after entering guard mode, all elements and protected electrical equipment all can break away from electrical network automatically, so coefficient of safety is big; the autospasy switch possesses the effect of Switching Power Supply simultaneously; when using this plate connector, stir the autospasy switch and can make electrical appliance open or close, enter guard mode; must again the autospasy switch be allocated to opening state; could power to socket once more, thereby two kinds of functions possess function admirable simultaneously.
Fig. 1 is the utility model circuit diagram.
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail:
Referring to Fig. 1, seal in autospasy switch JK in the middle of two electric power connection lines of this superpressure self-falling-off type security combination socket its input plug CT and accessory power outlet C2, be in series with insurance 8% at the beginning of the autospasy switch JK between level and the input plug, be parallel with alternating voltage indicating device N, can be voltmeter, be parallel with two branch roads between two electric power connection lines of JK level of autospasy switch and accessory power outlet C2: a branch road is tripping coil J and controllable silicon SCR series arm, this branch road also has the control utmost point branch road of controllable silicon SCR, is connected to tripping coil J lower end behind the control utmost point series limiting resistor R1 of controllable silicon SCR and the piezo-resistance RY; Another branch road is that two ends were connected in parallel on accessory power outlet two power lines after resistance R 2 was connected with relay indicating light NG, and for safety, the ground terminal of accessory power outlet C2 also links to each other by lead with input plug CT ground terminal.
Operation principle:
After autospasy switch JK closes in the circuit, power supply through JK to accessory power outlet C2 power supply, voltage just often, piezo-resistance RY is high-impedance state, controllable silicon SCR does not have trigger current and ends, tripping coil J no current is failure to actuate.When the line voltage superelevation, piezo-resistance RY is conducting state immediately, so electric current provides trigger current through RY, R1 to the bidirectional triode thyristor SCR control utmost point; make SCR conducting immediately; the tripping coil J adhesive of switching on drives autospasy switch JK and breaks away from electrical network automatically, reaches the purpose of safeguard protection.After entering guard mode, must again JK be allocated to " ON " shelves, could power to socket once more.
