Description
Affiliated technical field
The design is the anti-lightning strike anti-electrical network overvoltage technology of a kind of household electrical appliances.
Background technology
Known piezo-resistance is that die pressing product was prevented in lightning protection, but can damage during the piezo-resistance sustained overvoltage.Known relay or switch are a kind of mains switches, but all are air insulated usually between their electric shock, because the puncture voltage of air insulated is much smaller than the puncture voltage of some megohmite insulant, the damage that causes household electrical appliances still can be struck by lightning in stopped status.So prior art lacks a kind of comparatively ideal family non-electricity protector.
Summary of the invention
For solving the problem that the piezo-resistance sustained overvoltage can damage in the prior art; For solving the problem that existing relay or switch breakdown potential are forced down, I have designed to insert and have isolated tame non-electricity protector.
The technical scheme that the design deals with problems is: establish one in the normally closed conductive contact of relay side and can bear the insulation board of high puncture voltage, insulation board can insert under the magnetic force control that relay coil produces and make it isolate outage between the conductive contact moment.The contact logarithm is set as required, is set at two pairs here, and such relay is called the insertion disconnecting relay.One end of these two pairs of conductive contacts links to each other with an end of two inductance respectively, the other end of these two pairs of conductive contacts links to each other with an end of two discharging gaps respectively and as power supply two inputs, the other end ground connection of two discharging gaps, one end of the other end of an inductance and relay coil, one end of pressing every resistance links to each other and as power supply one output, the other end of relay coil, one end of two piezo-resistances of the other end of piezo-resistance and other links to each other, the other end ground connection that these two piezo-resistances are one, the other end of one the other end and another inductance link to each other and as another output of power supply.Piezo-resistance and inductance have been formed the moment surge absorber, and voltage limit is in the scope of safety between the line of piezo-resistance handle output, between line ground.When between line top-stitching ground during the overvoltage time lengthening, the magnetic force that the electric current by piezo-resistance, relay coil produces inserts between the relay conductive contact insulation board moment, has made its subsequent conditioning circuit of having isolated power-off protection.Two discharging gaps with extreme high voltage over the ground discharge prevention the safety of inserting disconnecting relay and subsequent conditioning circuit.
The design's beneficial effect is, a kind of tame non-electricity protector of desirable self no power consumption is provided for prior art.Moment of insulation board inserts and had both solved the problem that sustained overvoltage damages piezo-resistance, has also solved the problem that breakdown potential is forced down between the conductive contact of relay or switch.
