Description
Technical field
The present invention relates to information processing terminal technical fields, are especially a kind of electronic message terminal.
Background technology
Electric energy meter is the instrument for measuring electric energy, also known as kilowatt-hour meter, energy meter, kilowatt-hour table, refers to and measures various electricity
The instrument of amount.When electric energy meter is accessed circuit-under-test, just there is alternating current to flow through in current coil and potential winding, the two
Alternating current generates the magnetic flux of alternation in their iron core respectively；Alternating flux passes through aluminium dish, and vortex is induced in aluminium dish；
Vortex is acted in magnetic field by power again, to make aluminium dish obtain torque（Active torque）And it rotates.The power of load consumption
Bigger, bigger by the electric current of current coil, the vortex induced in aluminium dish is also bigger, keeps the torque that aluminium dish rotates bigger.
I.e. the size of torque is directly proportional with the power of load consumption.Power is bigger, and torque is also bigger, and aluminium dish rotation is also faster.Aluminium dish
It when rotation, and is acted on by the braking moment of permanent magnet generation, braking moment is opposite with active torque direction；Braking moment
Size it is directly proportional to the rotating speed of aluminium dish, aluminium dish rotates faster, and braking moment is also bigger.When active torque is reached with braking moment
When to transient equilibrium, aluminium dish is by uniform rotation.The consumed electric energy of load is directly proportional to the revolution of aluminium dish.When aluminium dish rotates, band
Dynamic counter, indicates the electric energy consumed.Here it is the simple procedures of electric energy meter work.Self-recovery fuse is a kind of
Overcurrent electrical protection component adds conductive particle using macromolecule organic polymer under conditions of high pressure, high temperature, vulcanization reaction
After sub- material, it is process by special technique.Traditional insurance silk overcurrent protection is only capable of protection once, has blown and needed to change,
And self-recovery fuse has overcurrent and overheating protection, restores dual function automatically.Self-recovery fuse is by passing through specially treated

The heat that the high current of double insurance silk generates makes polymer resin melt, and volume increases rapidly, forms high-impedance state, and operating current is fast
Speed reduces, to which circuit is limited and be protected.After troubleshooting, self-recovery fuse again receive by crystallisation by cooling, volume
Contracting, conducting particles re-form conductive path, and self-recovery fuse reverts to low resistive state, to complete the protection to circuit,
It need not manually replace.Using single-layer polypropylene film as medium, surface has been deposited one layer thin metal conduct and has led self healing capacitor
Electrode.When applying excessively high voltage, polypropylene screen electricity weakness is breakdown, and breakdown point impedance is substantially reduced, the electric current flowed through
Density increased dramatically, and metallization coating is made to generate high fever, and the metallic conductor around breakdown point evaporates rapidly loss, forms metal-plated
Layer clear area, breakdown point restore to insulate automatically.
Lightning protection device built in existing ammeter, most of through-current capacity is small, and response speed is slow, has a single function, ammeter is caused to transport
Row is unstable, while causing the service life of itself and ammeter short, for this purpose, proposing a kind of electronic message terminal.
