A kind of outdoor moistureproof intelligent electric meter
Technical field
The utility model is a kind of outdoor moistureproof intelligent electric meter, belongs to ammeter field.
Background technology
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 produces 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, so that aluminium dish obtains torque and rotates.The power of load consumption is bigger, by electricity
The electric current of streamline circle is bigger, and the vortex induced in aluminium dish is also bigger, and the torque for rotating aluminium dish is bigger.That is the size of torque
It is directly proportional with the power of load consumption.Power is bigger, and torque is also bigger, and aluminium dish rotates also faster.When aluminium dish is rotated, it is subject to again
The effect of the braking moment that permanent magnet is produced, braking moment is in opposite direction with active torque;The size and aluminium dish of braking moment
Rotating speed be directly proportional, aluminium dish rotates faster, and braking moment is also bigger.When active torque and braking moment reach transient equilibrium
When, aluminium dish is by uniform rotation.The consumed electric energy of load is directly proportional to the revolution of aluminium dish.When aluminium dish is rotated, counter is driven,
The electric energy for being consumed is indicated.Here it is the simple procedure of electric energy meter work.
