Abstract
The utility model discloses an induction type pulse electric energy meter which comprises a register, a rotary shaft and a disc. The utility model is characterized in that the electric energy meter is provided with a movable block, the place corresponding to the movable block is provided with a pulse generator, and the movable block is an accessory on a rotary component of the electric energy meter; the rotary component comprises the rotary shaft, the disc, a register gear and a character wheel. The utility model has the advantages of long service life, low cost, strong technical properties, easy mass production, and easy designed proportion factor between angular displacement of a rotor and output pulse within a wide range.
Description
The utility model relates to electric energy meter, relates in particular to inductance type pulse electric energy table.
Electric energy meter generally adopts photoelectric sensor or Hall sensor both at home and abroad at present.Photoelectric sensor has following shortcoming: 1. infrared transmitting tube is because of being energy dissipation device, and the power valve emissive power works long hours and can decay, and is difficult to accomplish the long-life; 2. infrared sensor is subject to ambient light influence reduction reliability; 3. the infrared receiving tube sensitivity that works long hours descends, and is difficult to equally accomplish the long-life.Hall sensor has following shortcoming: 1. because of electric energy meter is to adopt magnetic induction principle, Hall sensor itself needs a magnet, and it will destroy the original magnetic balance of electric energy meter, makes electrical energy meter accuracy can not get guaranteeing; 2. can not do too greatly because of magnet, cause the assembly precision requirement very high.
The purpose of this utility model is provides a kind of long working life, and manufacturability is strong, the inductance type pulse electric energy table that is easy to produce in batches.
The utility model is taked following measures in order to achieve the above object: inductance type pulse electric energy table comprises register, rotating shaft, disk.It also has motion block, is provided with pulse producer in the motion block corresponding position.Motion block is the condiment on the rotatable parts in the electric energy meter.Rotatable parts comprise rotating shaft, disk, register gear and character wheel.
The utility model has the advantages that:
1. long working life
The mission life of photo-electric impulse transfer element is decided by luminotron and photoelectric tube, be difficult to above 10 years by the mission life that limits this two device of cost, the mission life of magneto-electric impulse transfer element is decided by Hall element, and its mission life of same reason was difficult to above 20 years.
And under identical cost, the inductance type inverting element only is made up of common metal and magnetic conductor, and its electromagnetic property will be stablized manyly relatively, is easy to realize surpassing the mission life in 30 years.
2. cost is lower
Inductance type impulse transfer element is only formed semiconductor devices such as not needing the photoelectric tube Hall element by coil and magnetic conductor and motion block; And its motion block can be filled the post of by the condiment (sheet metal, magnetic inductive block etc.) on the rotatable parts (gear of disk, rotating shaft or register, character wheel) of electric energy meter.Part that no price is higher and circuit.Therefore, this photo-electric or the lower cost of magneto-electric pulses switch part are arranged under identical mission life.
3. manufacturability is strong, is easy to produce in batches
The motion block of inductance type pulses switch element and the action of a magnetic field of inductor distance just can not produce interference with the measurement or the damping magnetic field of Ferrari induction type electric energy meter mutually than length and as long as design is proper, so the requirement of other installation site is low far beyond magneto-electric impulse transfer element; And the magnetic field of itself is to have an effect in the space that limits, so it is not subjected to the interference of the light or the electromagnetic field of external environment, only needs simple magnetic shielding, even do not need shielding.The characteristics of this installation requirement and shielding requirements broad make it than current two class impulse transfer elements commonly used much better than manufacturability be arranged.
4. can in very wide scope, design the scale-up factor of angular displacement with the output pulse of electric energy meter rotor.
The motion block of electro-induction impulse transfer element is by being can show disk and directly fill the post of the time, utilize the same design of disc-shape that disk is rotated a circle and just can export several pulses, and motion block can pulses occur in several kilowatts of sides when investing on register gear or the character wheel, so wide scale-up factor is that other two kinds of impulse transfer elements are difficult to realize, and inductance type impulse transfer element can be done corresponding design according to user's different request for utilizations.
Elaborate below in conjunction with accompanying drawing:
Fig. 1 is an inductance type pulse electric energy matrix section structural representation,
Fig. 2 is the pulse producer frame principle figure.
Inductance type pulse electric energy table comprises register, rotating shaft 3, disk 1 etc.It also has motion block 2, is provided with pulse producer 4 in the motion block corresponding position.Motion block is the condiment on the rotatable parts in the electric energy meter, and rotatable parts comprise rotating shaft, disk, register gear and character wheel.
Pulse producer behind demodulator circuit, triggers monostable circuit for the oscillator signal that the oscillatory circuit that is embedded in the magnetic conductor by coil as an element sends, and obtains a signal pulse, and this pulse signal is through driving amplifying circuit output.
