For example, in one embodiment, when electric energy meter is accessed circuit-under-test, just there is alternation electricity in current coil and coil
Stream flows through, the two alternating currents generate the magnetic flux of alternation in their iron core respectively；Alternating flux passes through aluminium dish, in aluminium dish
In induce vortex；Vortex is acted in magnetic field be subject to power again, so that aluminium dish obtains torque (active torque) and rotates.It is negative
The power of load consumption is bigger, and bigger by the electric current of current coil, the vortex induced in aluminium dish is also bigger, makes what aluminium dish rotated
Torque is 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 rotates
It is faster.When aluminium dish rotates, and it is subject to acting on for the braking moment of permanent magnet generation, braking moment and active torque direction phase
Instead；The size of braking moment is directly proportional to the rotating speed of aluminium dish, and aluminium dish rotates faster, and braking moment is also bigger.When active torque
When reaching transient equilibrium with braking moment, aluminium dish is by uniform rotation.The consumed electric energy of load is directly proportional to the revolution of aluminium dish.Aluminium
When disk rotates, counter is driven, the electric energy consumed is indicated.Here it is the simple procedures of electric energy meter work.
Above-described embodiment only expresses embodiments of the present invention, therefore description is more specific and detailed, but can not be
And it is interpreted as the limitation to the scope of the claims of the present invention.It should be pointed out that for those of ordinary skill in the art, not
On the premise of departing from present inventive concept, various modifications and improvements can be made, these belong to protection scope of the present invention.Cause
This, the protection domain of patent of the present invention should be determined by the appended claims.
