Description
Technical field
This utility model is related to a kind of circuit, in more detail, is related to a kind of energy-saving circuit that can be disconnected automatically.
Background technology
When overvoltage protection refers to that protected circuit voltage exceedes predetermined maximum, disconnect power supply 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, just beyond the dielectric strength and pressure voltage of electrical equipment, therefore electrical equipment can generate heat,
Puncture and burn out even on fire.Clever junior partner cans say certainly, such as：Using the air switch and leakage for arriving during finishing
Non-electricity protector, but often miss overvoltage protector.When the instant high-voltage that thunder and lightning is produced is applied to varistor two ends,
Varistor resistance becomes infinitely small so that the high current that varistor is turned on and produces thunder and lightning introduces the earth, so as to protect
Power-supply device is not damaged by thunder and lightning, additionally, the overvoltage protector for arising at the historic moment has a lot, what is had is mounted in device interior, some dresses
In mains side, there is the protection of overvoltage protector, we, will be safer when using electrical equipment.
Fuse is used as conventional over-voltage and over-current protector, although simple structure, but it is widely used in high-low pressure and matches somebody with somebody
In electric system, and need long-term maintenance, when deployed between too long, melt because being aoxidized or being run in temperature height, make to melt
Bulk properties changes and wrong diagnosis, if in addition, fuse has when mounted mechanical damage so as to which sectional area diminishes, also can be in fortune
Cause wrong diagnosis in row.

Voltage recovers normal, is manually pressed by reset switch, and load starts positive often-have-electricity operation again.
Further, also including fly-wheel diode, the positive pole of fly-wheel diode is connected with the colelctor electrode of audion, afterflow two
The other end of the colelctor electrode of the negative pole of pole pipe connecting triode relative with relay is connected.In this utility model, fly-wheel diode
As fly-wheel diode, prevent the induction electromotive force that relay is produced during being opened or closed from damaging component.
Further, also including electric capacity, the electric capacity is in parallel with light emitting diode.In this utility model, electric capacity is used for supporting
Electromagnetism interference, improves the degree of accuracy of circuit.
The beneficial effects of the utility model are：
1st, using relay and triode switch speed is fast, good reliability, long service life, low cost advantage, this reality
Overvoltage or overcurrent with new can preparation in quick decision circuitry, it is not required that long term maintenance, simple structure is convenient
It is practical.
2nd, fly-wheel diode is adopted, the induction electromotive force that can effectively prevent relay from producing during being opened or closed
Damage component；Using light emitting diode, staff can be in time reminded, be easy to staff to pinpoint the problems in time and locate
Reason；Electromagnetic interference is resisted using electric capacity, the degree of accuracy of circuit is improved.
