Summary of the invention
It is an object of the invention to overcome drawbacks described above of the existing technology, it is anti-to provide a kind of positive non-buckle tripping device
Earth leakage circuit-breaker, it can protect personal safety and protect electric appliance, and itself will not be burnt out by high current.
In order to achieve the above objectives, the solution that the present invention takes is：A kind of forward direction non-buckle tripping device proof and electric leakage-proof safety
Switch, it includes plastic housing, electronic component, zero sequence transformer, circuit board, movable contact spring and movable contact, output end static contact and output
Stationary contact is held, electronic component is installed on circuit boards, and coil rack, static iron core, zero sequence transformer and mistake are also installed on circuit board
Current sensor is wound with main tripping coil on coil rack, and dynamic iron core passes through coil rack, and dynamic iron core covers upper reset spring, moves
Reset button is clamped on iron core, moving magnet, which is fixed on riveting, to be had in the insulation board of movable contact spring, and movable contact spring is through special flexible circuit conductor and input terminal
Conductive sheet is connected to electronic component, and the top of movable contact is directed at output end stationary contact, and circuit board is packed into plastic housing.
The current-leakage protection switch for forward non-buckle release machine is a concealed leakage protection switch, and zero sequence is both housed
Mutual inductor, and over-current sensor is housed, it can protect personal safety and protect electric appliance, and itself is not burnt by high current
It is bad, solve defect present in the prior art at one stroke.Its key technology is compact to be switched on or switched off power supply in electronic component face
Positive non-buckle tripping device, and with circuit board, movable contact spring, dynamic iron core, moving magnet and static iron core collectively form a kind of people, machine,
Electrical integrated control mechanism.
When pressing reset button with hand, the dynamic iron core that moving magnet will be pressed is sucked, when unclamping reset button,
Under the action of reset spring, moving magnet is won over from static iron core together with movable contact spring and movable contact, makes movable contact and output end
Stationary contact point contact is completed to be powered on.
When having electric leakage to occur in route, faint signal voltage is induced by zero sequence transformer, this signal is by electricity
Subcomponent amplification output makes dynamic iron core generate the magnetic (same sex identical with moving magnet polarity through main tripping coil (electromagnetic coil)
Repel each other), moving magnet is repelled to going on static iron core, and be attracted on Jing Tieshang at a terrific speed, disconnects power supply.It is absolute in human body
In safe current 10mA, power supply is disconnected with 19ms-25ms.
When there is overcurrent fault in circuit, over-current sensor induces overcurrent signal, and circuit also so acts.
