Compared with prior art, the beneficial effects of the invention are that:
(1) present apparatus, which provides one kind for the magnetic characteristic measurement of Anode saturable reactor iron core, can simulate various complex working conditions
Experiment porch, including simulate two iron cores stress variation and iron core air gap shapes and sizes variation, realize to iron core magnetic
The precise measurement of characteristic.
(2) fixture of the present apparatus is different from traditional iron core fixture.Since in actual motion, iron core has reached saturable reactor
To magnetic saturation state, in order to preferably simulate true operating condition, experimental provision needs very big number of ampere turns to increase iron core
Magnetic flux, this requires can be more around the number of turns, current excitation be big.Conventional brace does not have zigzag gap, and winding can only be in no folder
It is wound at tool, it can be extremely limited around the number of turns.The present apparatus uses sawtooth clamp, and this fixture not only makes iron core uniform force, and
And winding can be interted in the gap of sawtooth, increase iron core can be improved one times or more around the number of turns, the number of turns of winding, realize
Winding all standing makes iron core magnetic flux can achieve higher level to keep iron core magnetic flux distribution more uniform.Therefore can around
The non-sine pulsed current excitation closer to the true operating status of saturable reactor is passed through in group, just with traditional magnetic measurement
String excitation compares.
(3) conventional apparatus is often only applicable to the iron core of a kind of shape, size, limited by practical.The present apparatus is using adjustable
The sawtooth clamp and vibration proof fixture of section cooperate, and are suitable for different size, iron core of different shapes.Sawtooth clevis
Tool is using movable jaw come alignment jig size.Vibration proof fixture also installs dovetail groove and stay bolt additional, and iron core upper end folder is adjusted
The size and location of tool and iron core lower end fixture.
(4) two iron cores are likely to be vertical direction dislocation, it is also possible to be horizontally oriented dislocation, or the certain angles of rotation
Degree dislocation, these changes all can cause the shape of air gap to change.Semifixed, half liftable can using iron core one for the present apparatus
The mode of rotation simulates the variation of saturable reactor iron core longtime running air gap shape under complex working condition.The present apparatus is in activity
Four apex angles of plate install four stepper motors and cooperate four electric cylinders, and the subtle tune to movable upper plate height and angle may be implemented
It is whole.Obliquity sensor is installed additional in movable upper plate bottom surface, there are two effects: first is that leveling, wrong in only research iron core vertical direction
When position, it is desirable that movable upper plate is gone up and down under the premise of keeping integral level, just needs to be leveled with obliquity sensor at this time.
Second is that measurement angle, four electric cylinders lifting height differences can make movable upper plate and fixed upper plate form certain angle, realize iron core
It is rotary shifted, at this time by obliquity sensor can record different angle.Thus the different shape for simulating air gap, analyzes air gap shape
Influence of the variation of shape to iron core magnetic characteristic.
(5) the nonferromugnetic material interlayer of different-thickness is added among two pieces of iron cores.Nonferromugnetic material, which has, does not lead
The characteristic of magnetic, conductivity and air conductivity are close, thus different-thickness, surfacing nonferromugnetic material analog not
With the air gap of width.Device can be greatly simplified for air gap using sandwich generation, because of control width of air gap essence difficult to realize merely
The interlayer clamping of different-thickness need to only be can be realized with iron core using the method for interlayer, both can guarantee measurement in this way by close measurement
Precision, and influence of the different air gap width to iron core magnetic characteristic can be simulated.
(6) conventional brace is all to tighten bolt, does not consider that different stress is special to the magnetic of iron core and air gap
Whether property has an impact.Since the stress of iron core contact surface can not be measured accurately, tightening for bolt can be adjusted with sawtooth clamp
Torque replaces stress.This system, which is adjusted using torque spanner in sawtooth clamp, applies different torque on bolt, to analyze
Influence of the size of two iron core contact stress to iron core and air gap magnetic characteristic.
(7) this system reload temperature recorder monitors the temperature of iron core and each position of winding in real time, prevents iron core
It is overheated with coil.Moreover, the monitoring of temperature can provide stronger experimental basis for loss analysis, so that further analysis is full
With temperature rise situation of the reactor in actual motion.
(8) because fixed upper plate is fixed, movable upper plate liftable, two sides not necessarily remain in same level height, so
Using independent sawtooth clamp dovetail slideway.It not only can ensure that zigzag clamp bottom board promoted in opposite directions in this way, but also do not influenced to live
Dynamic upper plate lifting.
(9) it is adjusted in sawtooth clamp and installs disk on bolt additional, increase the stress between bolt and zigzag clamp bottom board
Area makes iron core stress more evenly.
