Description
Technical field
The present invention and a kind of RCCB, particularly a kind of can positive and negative wiring RCCB.
Background technology
Existing RCCB structure is typically because wiring board and assay device take in the upper end of RCCB or lower end
Electricity, the side of wiring board power taking is load-side, and the side of not power taking is into line side, if reversed, even if the line when product disconnects
Road plate is also at on-state, and wiring board its service life of long-term charging effect, if pressing test button, because product has broken
Open but still there is electric current test loop, cause product to burn phenomenon, and user because distribution line or distribution box design solid with product
When some modes of connection is inconsistent, causes to design or change loss.And layman can not carry out wiring well and install.Have
With l phase and handle mechanical linkage when portioned product wiring board and assay device power taking, that is, handle is in l phase during open position and breaks
Open, handle is in during closing position l phase closure, but product is threaded off, but handle locking is in "on" position, product circuit plate l
Mutually it is constantly in electriferous state with assay device, product therefore equally can be caused to burn phenomenon.When separately having a class product to disconnect, examination
Experiment device can not band conduct, but wiring board is powered all the time, no matter product be closure or open-circuit line plate be in all the time powered old
Change state, therefore has a strong impact on the service life of product.Therefore very big risk and deficiency are had with upper type.
Content of the invention
The present invention overcomes the shortcomings of that prior art exists, there is provided one kind i.e. l phase when product is in combined floodgate has the power supply to be
Wiring board and assay device are powered, RCCB energy normal work.When product is in gate-dividing state or when threading off, no matter handss
Where handle is in, and l phase power supply disconnects, and wiring board and assay device no l phase power supply are powered.Therefore no matter just connecing wire or anti-
Connect wire on product all no impact new can positive and negative wiring RCCB.
