Description
Technical field
The present invention relates to electrical facility technical field more particularly to a kind of leakage detecting warning system and leakage detecting are alert
Show equipment.
Background technique
Leakage detecting refers to a kind of scheme for detecting leaky, for detecting the dynamic of current mode earth leakage protector
Make electric current and detection is less than the uneven leakage current of current mode earth leakage protector movement, moreover it is possible to distinguish the leakage being harmful to the human body
Voltage and harmless induced voltage, can be effectively detected the leaky of electrical appliance.
SSR (Solid State Relay, solid-state relay) is the discrete electronic device by microelectronic circuit, power electronics
The noncontacting switch of power device composition realizes being isolated for control terminal and load end with isolating device.Solid-state relay SSR's
The small control signal of input terminal, reaches and directly drives large current load.
Existing leakage detecting evidence solution, is usually used leakage circuit breakers scheme, and leakage circuit breakers has as one
The electrical safety technique device of effect has been widely used, and is played the important and pivotal role.According to medical research, work as human body
Contact the alternating current of 50Hz (hertz), shock current 30mA (milliampere) and it is following when, the time of a few minutes can be born.This is just
Human electric shock's safe current is defined, to design and selecting earth leakage protective device to provide scientific basis, therefore, in mobile electricity
Device, moist place electric appliance where power branch leakage circuit breakers is set.It is the effective measures for preventing mediate contact from getting an electric shock.?
In national standard clear " in addition to air condition power socket, earth leakage protective device should be arranged in other power outlet circuits ".It leaks electricity dynamic
Making electric current is 30mA, actuation time 0.1s.I feel these to us it is daily be all it is highly important, ought to cause ours
Pay attention to.
Leakage circuit breakers in the existing leakage detecting evidence solution using leakage circuit breakers can be divided into single-phase type leakage
Electrical circuit breakers and three-phase type leakage circuit breakers.
The main component of single-phase type leakage circuit breakers is a magnet ring inductor, and firewire and zero curve use winding arranged side by side in magnet ring
Upper several circles of winding, there are also the secondary coil firewire for working as same phase and zero curves on magnet ring in normal work, what electric current generated
Magnetic flux just offsets, if will not induce a certain line of voltage in secondary coil has electric leakage, or does not connect zero curve, leads in magnet ring
The electric current of the firewire and zero curve crossed will be uneven, and generates the magnetic flux across magnet ring, and voltage is induced in secondary coil, leads to
Crossing electromagnet makes buckle releaser movement tripping.
The main component of three-phase type leakage circuit breakers has zero sequence current mutual inductor, electric sub-member plate, leakage tripping device and band
It is made of the breaker of overload and short-circuit protection.The earth leakage protective part of leakage circuit breakers is sensed by zero sequence current mutual inductor
Part, arithmetic and control unit, that is, control section and magnetictrip act, execution part forms.Protected main circuit is all
Phase, zero curve all pass through the iron core of zero sequence current mutual inductor, form zero sequence current mutual inductor primary side.The work of leakage circuit breakers is former
Reason substantially it is to be understood that leakage circuit breakers for simultaneously contact two-phase two-phase get an electric shock, cannot protect.
Referring to Figure 1, Fig. 1 is the leakage circuit breakers in the existing leakage detecting evidence solution using leakage circuit breakers
One example schematic.As shown in Figure 1, being by taking DZ15CE-40/490 leakage circuit breakers working principle as an example.As shown in Figure 1, should
L is electromagnet coil in DZ15CE-40/490 leakage circuit breakers, and when electric leakage can drive knife switch K1 to disconnect.Each bridge arm is used
Pressure resistance can be improved in two 1N4007 series connection.R3, R4 resistance value are very big, so flowing through the electric current very little of L when K1 closes, being not enough to make
It is disconnected at switch K1.R3, R4 are the equalizing resistance of silicon-controlled T1, T2, can be reduced to silicon-controlled resistance to pressure request.K2 is test
Button plays simulation electric leakage.Test button K2 is pressed, K2 is connected, outside line firewire is equivalent to greatly there is electric leakage, in this way,
Vector sum across the electric current of the three-phase power line and zero curve of magnet ring is not zero, and the both ends a, b of the detection coil on magnet ring just have
Induced voltage output, the voltage trigger T2 conducting immediately.Since C2 is precharged with certain voltage, after T2 conducting, C2 just through R6,
R5, T2 electric discharge make to generate voltage triggered T1 conducting on R5.After T1, T2 conducting, the electric current for flowing through L increases, and makes electromagnet action,
Driving switch K1 is disconnected, and the effect of test button is can to check whether present apparatus function is intact at any time.Electrical equipment electric leakage causes
The principle of electromagnet action is identical with this.R1 is varistor, plays overvoltage protection.This also essentially constitutes electric leakage
Most important earth leakage protective function in the working principle of breaker.
But at least there are the following problems in the prior art for inventor's discovery:
The existing leakage detecting evidence solution using leakage circuit breakers, and palpus two or more samples power line, needs to match
It closes indoor inlet wire and needs fixed volume place and place leakage breaker.

3. leakage detecting warning system as described in claim 1, which is characterized in that the light-emitting flash warning diode assembles
Buzzer is set, the buzzer provides sound and light program when there are drain conditions.
4. leakage detecting warning system as described in claim 1, which is characterized in that the coil configures Programmable logical controller
Device, the coil get in touch to warn in the presence of electric leakage feelings by the programmable logic controller (PLC) and remote back-office of the configuration
Condition.
5. leakage detecting warning system as described in claim 1, which is characterized in that the coil configures single-chip microcontroller or embedded
System, the coil is got in touch by the single-chip microcontroller and remote back-office of the configuration, and to warn, there are drain conditions.
6. leakage detecting warning system as described in claim 1, which is characterized in that in input terminal electric leakage, described the
One input terminal and second input terminal form loop of electric leakage, and the third output end and the 4th output end are to close lock at this time
State, the output end form access, the light-emitting flash warning diode group work, and the light-emitting flash warns diode group
The power more slightly larger than the solid-state relay is consumed at this time.
7. leakage detecting warning system as described in claim 1, which is characterized in that described when the input terminal is without electric leakage
First input end and second input terminal are formed without loop of electric leakage and no current generates, the third output end and the described 4th
Output end is the state of opening a sluice gate at this time, and the light-emitting flash warning diode group forms no loop of electric leakage at this time and no current generates,
No current generates the input terminal at this time, and no current generates the output end at this time.
8. a kind of leakage detecting caution device, which is characterized in that detectd including electric leakage as claimed in any one of claims 1 to 7
Survey warning system.
