Description
Technical field
This utility model is related to electrical equipment technical field, specially a kind of anti-reverse ammeter being easily installed.
Background technology
The abbreviation of electric energy meter, is used to measure the instrument of electric energy, also known as kilowatt-hour meter, energy meter, and electric energy meter, kilowatt-hour table,
Refer to measure the instrument of various electrical quantities, present ammeter is generally divided into mechanical electricity meter and intelligent electric meter, ammeter be in people's life not
The small electromechanical that can lack.When electric energy meter is accessed circuit-under-test, in current coil and potential winding, just there is alternation electricity
Stream flows through, and this two alternating currents produce the magnetic flux of alternation respectively in their iron core；Alternating flux passes through aluminium dish, in aluminium dish
In induce vortex；Vortex is acted on by power, so that aluminium dish obtains torque (active moment) and rotates in magnetic field again.Negative
The power carrying consumption is bigger, and bigger by the electric current of current coil, the vortex inducing in aluminium dish is also bigger, so that aluminium dish is rotated
Moment is bigger.
But it is not very firm that traditional mechanical electricity meter is installed when using, and ammeter often occurs the aobvious of reversion
Existing.
