Description
Technical field
The present invention relates to a kind of circuit, in more detail, it is related to a kind of circuit structure of efficient energy-saving.
Background technology
When overvoltage protection refers to that protected circuit voltage exceedes predetermined maximum, so that power supply is disconnected or make controlled plant electricity
A kind of low protected mode of pressure drop.As long as comparing proper use of pressure cooker that just can be very safe, invisible impalpable electricity is more
Danger, if voltage is too high suddenly, the just dielectric strength beyond electrical equipment and pressure voltage, electrical equipment can therefore generate heat,
Puncture and burn out even on fire.Clever junior partner cans say certainly, such as: using the air switch arriving and leakage during finishing
Non-electricity protector, but often miss overvoltage protector.When the instant high-voltage that thunder and lightning produces is applied to varistor two ends,
Varistor resistance becomes infinitely small so that the high current that varistor turns on and produces thunder and lightning introduces the earth, thus protecting
Power-supply device is not damaged by thunder and lightning, additionally, the overvoltage protector arising at the historic moment has a lot, have is contained in device interior, some dresses
In mains side, there is the protection of overvoltage protector, we, will be safer when using electrical equipment.
Fuse as conventional over-voltage and over-current protector although structure is simple, but it is widely used in height and is press-fitted
In electric system, and need long-term maintain, when deployed between too long, melt, because of temperature height in being aoxidized or running, makes to melt
Bulk properties change and wrong diagnosis, if in addition, fuse have mechanical damage when mounted so as to sectional area diminishes, also can fortune
Cause wrong diagnosis in row.
Content of the invention
The purpose of the present invention is to overcome the deficiencies in the prior art, provides a kind of circuit structure of efficient energy-saving, and it is using continuing

Within normal range, light emitting diode ends value, and the base stage no current of audion passes through, and audion is in cut-off state, therefore
Relay is failure to actuate, and electric switch is in closure state as normally closed switch, and power supply is load normal power supply；Conversely, when power supply carries
For overtension, that is, circuit working current value is excessive, and LEDs ON simultaneously lights, and for audion provide base stage electricity
Stream, audion saturation conduction, relay obtains electric suction with electric switch disconnects, thus cutting off load, playing a protective role, being unlikely to
Allow load overvoltage to run, both can extend load service life, again can be with energy saving；After cut-out load, wait supply voltage
Recover normal, be manually pressed by reset switch, load starts positive often-have-electricity again and runs.
Further, also include fly-wheel diode, the positive pole of fly-wheel diode is connected with the colelctor electrode of audion, afterflow two
The negative pole of pole pipe is connected relative to the other end of the colelctor electrode of connecting triode with relay.In the present invention, fly-wheel diode conduct
Fly-wheel diode, prevents the induction electromotive force that relay produces during being opened or closed from damaging component.
Further, also include electric capacity, described electric capacity is in parallel with light emitting diode.In the present invention, electric capacity is used for resisting electricity
Magnetic disturbance, improves the degree of accuracy of circuit.
The beneficial effects of the present invention is:
1st, utilize that relay and triode switch speed is fast, the advantage of good reliability, long service life, low cost, the present invention can
It is not required that long term maintenance, structure is simple, convenient and practical for overvoltage in the quick decision circuitry with preparation or overcurrent.
2nd, adopt fly-wheel diode, can effectively prevent the induction electromotive force that relay produces during being opened or closed
Damage component；Using light emitting diode, staff can be reminded in time, be easy to staff and pinpoint the problems in time and locate
Reason；Electromagnetic interference is resisted using electric capacity, improves the degree of accuracy of circuit.
