Accompanying drawing explanation
Fig. 1 is a kind of table case intelligent leakage circuit breaker structural representation that the utility model proposes.
Detailed description of the invention
Reference Fig. 1, a kind of table case intelligent leakage circuit breaker that the utility model proposes, including: chopper 1,
Current transformer 2, electrical apparatus release 3, trigger 4, positor 5 and communication device 6.
Chopper 1 is arranged in triple line, and triple line disconnects along with being opened or closed of chopper 1 or leads
Logical.
Current transformer 2 is arranged in triple line and is positioned at chopper rear end, under normal condition, in triple line
Do not have electric energy to reveal, current transformer 2 does not produce electric current；Under triple line leakage condition, current transformer 2
Produce electric current.
Electrical apparatus release 3 is connected with current transformer 2 and installs near chopper 1, and current transformer 2 produces
Under current status, electrical apparatus release 3 electric and control chopper 1 and disconnect.
Trigger 4 is provided with input, the first outfan and the second outfan, and input connects current transformer 2,
Its first outfan connects positor 5 by delay unit 7, its second outfan connecting communication device.Reset
The corresponding chopper 1 of device 5 is installed.
Current transformer 2 produces under current status, flip-flop operation, and trigger has two kinds of duties.
Under first state, trigger 4 obtains electric generation first and triggers signal and by the first outfan output to control again
Position device 5 works, and positor 5 produces reset signal control chopper 1 and closes after obtaining the first triggering signal.
The number of times triggered by current sensor in Preset Time when trigger 4 is no less than predetermined threshold value, such as three
Being triggered in Miao three times, trigger 4 enters the second state, and it produces the second triggering signal by the second output
End output, communication device 6 obtains the second triggering signal, and communication device 6 triggers under signal driving second
Communication information is sent to goal-selling.
In present embodiment, owing to, under positor 5 duty, electrical apparatus release 3 is still in duty,
So, positor working strength should be greater than electrical apparatus release 3.Such as, when electrical apparatus release 3 and positor 5 are all by electricity
Magnetic field controls chopper 1 and works, then the electromagnetic field intensity that positor 5 produces should be greater than what electrical apparatus release 3 produced
Electromagnetic field intensity, and positor 5 produce electromagnetic field intensity be at least electrical apparatus release 3 produce electromagnetic field intensity
Twice.
In present embodiment, after positor 5 controls chopper 1 Guan Bi, triple line is due to electric leakage, so electric
Producing electric current in flow sensor, then electrical apparatus release 3 controls chopper 1 and disconnects.In order to avoid positor 5 is right
The work of electrical apparatus release 3 produces interference, and in present embodiment, reset signal is instantaneous signal, i.e. reset signal
Being only capable of control chopper 1 moment Guan Bi, it does not have the Sustainable Control ability to chopper.This embodiment party
In formula, the setting of delay unit 7, property while positor 5 and electrical apparatus release 3 work can be avoided, thus protect
Card electrical apparatus release normally works.
In present embodiment, trigger 4 is set, and trigger 4 first state and the second state are set, and
Repeatedly attempt close circuit breaker 1 under first state, so, such as can access excessive in circuit non-faulting sexual abnormality
Automatic recovery of power supply during power amplifier, alleviates maintainer burden, and is easy to citizen's electricity consumption.
In present embodiment, the number of times triggered by current sensor in Preset Time when trigger 4 is no less than
Predetermined threshold value, trigger 4 enters the second state, i.e. enters second in the case of getting rid of non-faulting sexual abnormality
State, now, by communication device 6 to goal-selling such as maintainer transmission announcement information, so, can
Guilty culprit table case is overhauled by notice maintainer in time, thus, it is ensured that citizen's electricity consumption.
In present embodiment, the communication modes that communication device 6 uses includes wifi, 3G, 4G and VPNVirtual
Private Network, one or more in VPN (virtual private network).Table case is had with storage in communication device 6
Address, its Content of communciation sent includes breaker opening times and table case address, in order to maintainer is quick
Confirm bug list case, improve maintenance efficiency.
The above, only this utility model preferably detailed description of the invention, but protection model of the present utility model
Enclose and be not limited thereto, the technology model that any those familiar with the art discloses at this utility model
In enclosing, conceive in addition equivalent or change according to the technical solution of the utility model and utility model thereof, all
