Description
Technical field:
The present invention relates to experiment teaching instrument fields, and in particular to a kind of concentric electrode static field simulation device and use
Method.
Background technique:
Electrical body ambient static electricity field distribution is understood and grasped, it is particularly significant for certain scientific researches and engineering technology, but
It generally is difficult to calculate electrostatic field distribution with theoretical method, also extremely difficult, the measurement of electrostatic field is directly measured with instrument
Simulation is generally used, using steady high voltage system analog electrostatic field, is determined by the Potential Distributing in measurement constant current field
The Potential Distributing of electrostatic field.In Physics Practical Courses, " simulation of electrostatic field is described " experiment belongs to basic experiment,
Instrument number of users and frequency of use are very high, according to teaching material requirement and course arrangement, the concentric electrode knot in teaching practice
Structure is most widely used.
With steady high voltage system analog electrostatic field, steady high voltage system is established, the electrode of current field is made into using good conductor, and
Non-conductor with resistivity much larger than electrode resistance rate serves as conductive matter, such as conductive crystallite, tap water, depleted copper sulfate solution
Deng laboratory apparatus in practical application, water tank type analog electrostatic field mapping instrument and conductive micro-crystal electrostatic field plotter are relatively common.
The generally square in cross-section sink of water tank type analog electrostatic field mapping instrument basic structure, each sink is interior to place a set of metal electricity
Pole in the fixed electrode position of slot bottom aperture, and is connect with slot external circuit.Sink injects tap water as dielectric when experiment, sets
In on measurement bay, usually using the double-deck probe as measurement, the tool of record.Water tank type analog electrostatic field mapping instrument is sudden and violent in use
Some problems are revealed, such as the non-design level regulating device of sink structure, when experiment cannot level water layer, it cannot be guaranteed that conductive be situated between
The conductivity of matter is uniform everywhere, therefore will form very big measurement error；The positioning of double-deck probe is due to its design feature and can not
The foozle avoided also can increase large error to measurement；Although having taken leak-proof measure, instrument after a period of use,
Still drainage frequent occurrence at the perforation of electrode, and there are water to the etching problem of metal parts；Metal electrode in sink
Type and mutual alignment cannot change once determining, lack the flexibility etc. used.
Conductive micro-crystal electrostatic field plotter avoids the problem of more water tank type instrument, is led using conductive crystallite as bad
Body carries out data acquisition using synchronous probe, and measurement probe and conductive crystallite plate are kept in contact realization circuit communication, mobile to synchronize
Probe finds satisfactory potential point, utilizes record probe records data acquisition.Since structure simple operations are convenient, quilt
It is widely used.But this kind of instrument also exposes some defects after long-term use: measurement probe should be with electrode plate perfect condition
Point contact, but due to technique realize it is difficult and prevent using when fracture, measurement probe generallys use the brass bar of diameter 2mm or so
Material, probe tips are processed into the structure with point, instrument using when be steadily contacted to make to measure probe and conducting medium, can exert oneself
Pressing measurement contact device, also needs that stroke is back and forth to find the position of required potential point with measurement probe, when instrument uses one section
After time, the tip portion for measuring probe can gradually be worn into a rough face, while contact area will increase, and lead
When causing survey measurements, the reading on display screen is unstable, floats up and down, to have found the equipotential of mistake in measurement
Point makes description image large error occur；After measuring probe abrasion, probe height is reduced, so that measuring probe in experimentation
It is affected with the synchronism of record probe, that is, requirement of two probes in same plummet face cannot be guaranteed up and down after wearing, and make
Measurement error is obtained to become larger；Synchronous probe structure can introduce error, and synchronous probe is matched by metallic supports such as pedestal, handle and connection sheets
The compositions such as measurement probe, nut are closed, since synchronous probe is exposed in air for a long time, the contact for measuring probe and connection sheet is easy
It gets rusty, leads to the unstable of circuit on-state, simultaneously as the influence of iron rust, causes resistance to become larger, deviate measured value true
Real value seriously affects experimental result；In addition, synchronizing, probe is independent of one another with apparatus subject, is separated from each other, to placement platform requirement
It is higher.
Summary of the invention:
Technical problems to be solved of the present invention are:
1, innovative design product structure, by probe it is mobile with measure, interrecord structure is integrated together, using measurement probe and
Probe coaxial configuration is recorded, shortens measurement circuit, reduces measurement arm contact resistance, eliminates and takes a mistake caused by instrument itself
Difference improves DATA REASONING precision；
2, using conductive crystallite rather than water as non-conductor make electrode plate, avoid water tank type analog electrostatic field instrument
Problems；
3, be used for a long time after measure probe and electrode plate sliding frictional wear it is serious, probe contact area it is uneven and
Data error caused by increasing increases, and improving contact structures reduces the measurement probe degree of wear, solves to make to measure probe because of abrasion
Shortening causes to record probe and measures the problem of probe is detached from same plummet face, influences measurement result.
For this purpose, the present invention provides a kind of concentric electrode static field simulation device and application method, which is suitable for mould
Electrostatic field distribution between the quasi- long straight coaxle cylinder shape electrode of method research, is also applied for the Experiment of College Physics " simulation of electrostatic field

2) coordinate system is established, is vertical with probe vertical, horizontal moving direction using the interior electrode centers point of concentric electrode plate as origin
Axis of abscissas establishes rectangular coordinate system；
3) handle traverse measurement probe is held to interior electrode centers position, and the pointer observed on longitudinally, laterally guide rail slide block should refer to
At 0 graduation mark of respective scale；
4) moving handle observes voltmeter simultaneously, when reaching required potential point, observes and records the finger on longitudinally, laterally guide rail
Scale value corresponding to needle, and recorded in a manner of transverse and longitudinal coordinate value；
5) using the above method obtain experimental data be series of points coordinate value, carry out drafting distribution map of the electric field, calculate survey
When measuring error these data are marked one by one on graph paper, carries out follow-up data processing, or the coordinate of these points is inputted into meter
Calculation machine completes Data Processing in Experiment by the data processing of computer software and graphics processing function.
