The utility model has the advantages that with the electronic safety device without sparks installed in electric circuits, the power can be cut off immediately if faults of overload, short pass and creepage occur, and the power supply is recovered after the faults are removed. The utility model has simple structure, low cost and convenient generalization.
Description
The utility model relates to a kind of being installed in the circuit, prevents to cause because of electricity consumption overload, line short, line electrical leakage the protective device of fire, is a kind of no-spark electronic security device specifically.
At present, various electric users, as residential electric power, office building electricity consumption, factory's electricity consumption etc., often breaking out of fire:, make the circuit heating as the excess load electricity consumption owing to underlying cause; Supply line is throughout the year in bad repair and aging, causes live wire and zero line short circuit easily, and this short circuit will cause fire disaster within 4 seconds～10 second time; Supply line and electrical leakage etc. all can initiation fires, make lives and properties be subjected to heavy losses.
The utility model purpose is to overcome the deficiency in the above-mentioned technology, a kind of no-spark electronic security device is proposed, make electric user's inside power supply circuit, no matter any faults such as load overload, short circuit, electric leakage occur, can stop user's in-line power immediately, can breaking out of fire, after fault is got rid of, continue again to send.
The utility model purpose is realized by following technical scheme:
This no-spark electronic security device, shell and bottom heating panel flexibly connect, power supply indicator light outside it is characterized in that on shell, being equipped with, interior power supply indicator light, overload (short circuit) malfunction indicator lamp, the leak current fault indicator light, fuse, manual self-lock switch, reset switch, on the heating panel of portion silicon-symmetrical switch is housed in the enclosure, printed substrate is installed on the bracing frame of being made up of carrying bolt.
Between heating panel and the shell insulating washer is housed.Circuit on the printed substrate comprises following a few part: (1) main circuit, (2) circuits for triggering, (3) signal voltage source circuits, (4) secondary singal voltage source circuit, (5) inner DC power-supply circuit.Wherein: (1) main circuit, by silicon-symmetrical switch and advance, go out circuit and outer power supply indicator light, interior power supply indicator light is formed, (2) circuits for triggering, by manual self-lock switch, the leak current fault switch, overload (short circuit) breakdown switch, fault display circuit is formed, (3) signal voltage source circuits, by transformation, rectification, filter circuit is formed, (4) secondary singal voltage source circuit, by the secondary singal voltage source, the overload reset switch, the electric leakage reset switch is formed, (5) inner dc power supply is by the capacitance decompression device, rectifier, filter and fuse are formed.
The operation principle of no-spark electronic security device is:
When the normal electricity consumption of user, press manual self-lock switch (6) with hand, connect circuit, silicon-symmetrical switch (9) internal switching and send electricity, at this moment, the output of leak current fault switch (10), overload (or short circuit) breakdown switch (11) is a high-tension electricity.When the user normally has a power failure, click manual self-lock switch (6) again with hand, make its short circuit, silicon-symmetrical switch (9) inside disconnects and has a power failure, and at this moment, the output of leak current fault switch (10), overload (or short circuit) breakdown switch (11) is a high voltage.
During with indoor normal power supply, electricity consumption excess load (or internal wiring short circuit), at this moment, overload (or short circuit) signal voltage source (14) output HIGH voltage, be added to the input of overload (or short circuit) breakdown switch (11), be output as low-voltage, this low-voltage makes inner disconnection of silicon-symmetrical switch (9) and has a power failure.The moment that has a power failure, secondary singal voltage source (13) is by diode D
3Export a high voltage, be added to the input of overload (or short circuit) breakdown switch (11), keep being output as low-voltage, make inner disconnection of silicon-symmetrical switch (9) and stable power failure.After fault was got rid of, when clicking overload (or short circuit) reset switch (7) with hand, secondary singal voltage source (13) was by diode D
3Export a low-voltage, be added to the input of overload (or short circuit) breakdown switch (11), make to be output as high voltage, silicon-symmetrical switch (9) internal switching and sending.
During with indoor normal power supply, under the line electrical leakage situation, at this moment, a signal voltage source (15) output HIGH voltage that leaks electricity is added to the input of leak current fault switch (10), and is output as low-voltage, makes that silicon-symmetrical switch (9) is inner to be disconnected and have a power failure.Have a power failure moment, secondary singal voltage source (13) is by diode D
4Export a high voltage, be added to the input of leak current fault switch (10), keep being output as low-voltage, make inner disconnection of silicon-symmetrical switch (9) and stable power failure.After fault was got rid of, when clicking electric leakage reset switch (8) with hand, secondary singal voltage source (13) was by diode D
4Output LOW voltage is added to the input of leak current fault switch (10), makes to be output as high voltage silicon-symmetrical switch (9) internal switching and sending.
The utility model advantage is simple and reasonable for structure; Easily manufactured, cost is low, is convenient to promote the use of.It is installed in the usefulness electric line of residential building or commercial mansion, factory and enterprise etc., in case overload, when short circuit or leak current fault, the utility model product can stop in-line power immediately, prevent the generation of fire, guarantee life security and property are not suffered a loss, after fault is got rid of, continue power supply again, easy to use.
