Technical field
It the utility model is related to a kind of breaker, the unimodular number multifunctional electric leakage open circuit of particularly a kind of non-directional wiring
Device.
Background technology
Electronic type residual current circuit breaker predominantly cuts off main circuit when main line has leakage current to reach working value, so as to anti-
The only various active protection products occurred by accident, its operation principle is that the detection unit of RCCB detects main circuit
Leakage current powered to voltage trip device so as to excite pcb board to open logic switch and form loop so that voltage trip device
Act and promote the operating mechanism of RCCB to disconnect main line and realize the defencive function, but for existing product, because entering
Line can only be connected to RCCB and cut-off rear not charged one end, and reason is if inlet wire is connected on normal powered one end, and voltage takes off
Button device is also connected on this one end, and can not be connected on opposite end, because all there was only not charged, leakage, breaking after the open circuit of one end in any case
After device closes a floodgate, the logic switch of pcb board is in the state of cut-offfing, and when RCCB excites work, the logic switch of pcb board closes
Close, voltage trip device work, main circuit is disconnected, but because the logic switch of pcb board is closed causes voltage trip device shape
Into loop, logic switch can not be closed again, unless the loop that voltage trip device is formed simultaneously switches off, but because of not this function,
It is constantly in and is powered shape, voltage trip device works until being damaged always.
Conventional unimodular number multifunctional electric leakage circuit breaker wiring direction is often fixed, can only be only had on same product
One end of incoming cables, a leading-out terminal, end of incoming cables can not be again as leading-out terminals, and leading-out terminal can not be again as end of incoming cables, although production
Key position has lettering prompting on product, but the situation of imprudence reversal connection wire can not be complete during using this product by user
Avoid, if now breaker closing and pressing test button, product can be burnt out, so as to cause unpredictable consequence.

Embodiment
With reference to embodiment and accompanying drawing, the utility model is described in further detail.
Embodiment
The unimodular number multifunctional electric leakage circuit breaker of non-directional wiring as shown in figs 1 to 6 includes housing 1, handle 2, liner plate
3rd, conducting bridge 4, fax spring 5, support 6 and tripping mechanism (tripping mechanism is the common tripping mechanism in market, is existing technology,
It is not set forth in detail herein), described support side raises into top-end 61 and passes through described liner plate and can do spacing arc fortune
Move, the stopper slot 31 provided with the raised activity of top-end 61 supplied on support on liner plate, the raised top-end on described support
61 stopper slot 31 on liner plate 3 is set and spacing arc motion can be done in stopper slot 31, and institute is jacked up on described top-end 61
The fax spring 5 stated, the fax spring one often contact magnet steel 7, and other end is often located on the liner plate when the breaker cut-offs
Border on, described conducting bridge 4 is installed in liner plate 3, and is positioned by described liner plate 3, described one end of conducting bridge 4 with it is described
The one end of fax spring 5 it is face-to-face, the other end is positioned on the position on dynamic button opposite.Support 6 is with tripping 8 coaxially in the first support
On axle, the supply lines of pcb board 9 is connected to one end of the conducting bridge 4, and after the breaker closing, PCB is connected to civil power, open circuit
Device cut-offs that rear pcb board is not charged, and dynamic one end of button 10 is connected to resistance and reconnected in the N poles of breaker.Described magnet steel and electricity
Spring is passed to be in same potential, after the breaker closing, the fax spring is pressed to the conducting bridge by the support top-end,
The fax spring and the conducting bridge are located at the side of the liner plate, and handle is located at the opposite side of the liner plate.Jing Anniuchu is same
One end of point joint test resistance and voltage trip device, the voltage trip device other end are connected to that pcb board is conditional to be supplied
Electricity is in described conducting bridge.
The space for the insertion of torsion spring main body is provided with liner plate, it is convex that space periphery is provided with the gear for preventing torsion spring from skidding off the space
33, the space is positioned at by the cooperation between shell and liner plate for the movable breach of one end, torsion spring keeping off on convex being provided with
It is interior.The boss 32 for torsion spring end overlap joint is provided with the border of liner plate.It is provided with liner plate and conducting bridge is stuck on liner plate
Screens, what the projection 33 that the screens is set up by being spaced in intervals on liner plate was realized.
The breaker closing, the moving contact contact with static contact, and the magnet steel is powered, the idiostatic fax spring
It is powered, while combined floodgate, the fax spring connected together with the conducting bridge it is overall powered, because the pcb board passes through wire
One end of conducting bridge is connected to, the PCB is now powered, and the breaker is in band guard mode, the voltage trip device
The pcb board is wired to, but because PCB operation principle is to sense that main circuit leaks off to regulation and let out by magnet ring
After electrical leakage quantity, the signal triggering pcb board of granting is opened chip switch formation path and powered to the voltage trip device, the dropout
Device action promotes the breaker to disconnect main circuit, simultaneously as the fax spring while return that the support return is propped up
And departing from the conducting bridge, the conducting bridge power supply is cut off, therefore the pcb board and the voltage trip device are also cut off back
Road, do not reoperate.
Only so can be that pcb board takes off with voltage because no matter after that terminated line, breaker closing by non-directional wiring
It is powered in running order to detain device, during electric leakage, after breaker trigger condition disconnects, pcb board with electrical apparatus release is no longer powered is unable to shape
Into path, the voltage trip device can not form loop, so as to will not continue to action damage breaker
And the operation principle of traditional non-non-directional RCCB is：Voltage trip device is also access pcb board, but because
Pcb board is linked into the phase line of breaker one end, and junction is not set cut-offs synchronous breaking device with breaker master, causes electricity
Pressure-off button only has access the phase line pole of the not charged one end in the rear end after breaker cut-offs, and can not be linked into cut-off before often it is powered
In the phase line of one end, so as to can only one end inlet wire, and can not reversed breaker, but because the thing of the reversed heart of imprudence still can
Occur, and cause uncontrollable consequence, once reversed line, if not leaking electricity generation, breaker can be in running order, potential
Inevitable risk formed, as long as RCCB action main circuit can be cut off, but the loop of the voltage trip device of breaker
After being formed by PCB chip switch loop, untill just constantly the straight cause of action is burnt out always, such case is particularly monthly
Routine will necessarily produce when touching the button.And such case is many.The utility model patent is by designing described in entirely so solution
Problem, avert risks.
The advantages of general principle of the present utility model, principal character and the utility model has been shown and described above.One's own profession
The technical staff of industry is it should be appreciated that the utility model is not restricted to the described embodiments, described in above-described embodiment and specification
Simply illustrate principle of the present utility model, it is in the art common on the premise of the spirit and scope of the utility model is not departed from
Technical staff simple change and replace all be within the scope of protection of the utility model.
