Abstract

Provided is a stimulated electrostatic field plotter, mainly applied to physics experiment teaching in universities and colleges and comprising a simulated electrostatic field tester, a binding post I, an electrode I, a coordinate plate, coordinate plate feet, an electrode I fixing screw, an electrode II fixing screw, a water channel, tap water, an electrode II, a binding post II and a metal probe; the simulated electrostatic field tester comprises a cabinet, a voltmeter, a binding post III, a binding post IV and a binding post V; the potential of any position of a tap water electric medium in the water channel can be measured and displayed by the voltmeter through the metal probe; the position of the metal probe can be directly read through coordinates on the coordinate plate. The stimulated electrostatic field plotter thoroughly solves the problem that a probe of a double layer structure apparatus and plotting points do not on a same line and makes plotting visual and simple; in addition, conductive media and electrodes are easy to replace and clean.

Description

The analog electrostatic field drawing apparatus

Affiliated technical field

The utility model relates to a kind of analog electrostatic field drawing apparatus, is mainly used in large, special secondary school universities and colleges physics experiment teaching.

Background technology

Electric field can be described with the space distribution of electric field intensity and current potential, under general clear condition, find the solution electrostatic field more complicated and difficulty with mathematical method, often measure by means of experiment, and directly the distribution of measurement of electrostatic field is very difficult, at first, surveying instrument can only adopt electrostatic intrument, and the magneto-electric ammeter of general use has electric current just to respond, and electrostatic field does not have electric current, and is naturally inoperative; Secondly, because introducing electric field, measurement instrument can change because the electrostatic induction effect makes former electrostatic field.For this reason, commonly use the next indirect measurement of electrostatic of the method field of steady current field stimulation electrostatic field, this kind experimental technique is " simulation ".The conducting medium of existing analog electrostatic field drawing apparatus is mainly tap water, conductive crystallite, but, no matter conducting medium is tap water or conductive crystallite, all exist obvious deficiency: steady current field and plotting board are two-layer for the up and down, its probe and describe the pen be separately fixed at the up and down two shell fragments on, when describing, probe and tracing point are difficult on same straight line, therefore, will bring larger error; In addition, apparatus structure is complicated, complex operation, especially during the tap water conducting medium, is difficult for changing conducting medium and electrode.

Summary of the invention

In order to solve the deficiency of existing analog electrostatic field drawing apparatus, the utility model provides a kind of novel analog electrostatic field scanner, this analog electrostatic field drawing apparatus has not only solved probe and has described the disalignment problem of pen, make and describe to become directly perceived and simple, and conducting medium, electrode are easily changed and clean.

The technical scheme that its technical matters that solves the utility model adopts is: it contains analog electrostatic field tester, binding post I, electrode I, template, template footing, electrode I gib screw, electrode II gib screw, tank, tap water, electrode II, binding post II, metal probe.The analog electrostatic field tester contains cabinet, voltage table, binding post III, binding post IV, binding post V.Fill appropriate tap water dielectric in tank.Be printed on coordinate on template, the electrode I is fixed on template by electrode I gib screw, and the electrode II is fixed on template by electrode II gib screw, and the binding post I is housed on the electrode I, and the binding post II is housed on the electrode II, and template is placed in tank.The analog electrostatic field tester provides AC power by binding post III, binding post V, the binding post I is electrically connected to the binding post III by wire, the binding post II is electrically connected to the binding post V by wire, therefore, obtain the AC power that the analog electrostatic field tester provides by binding post III, binding post V on electrode I and electrode II.Metal probe is electrically connected to the binding post IV by wire, in tank in the tap water dielectric electromotive force of optional position measure to be shown by voltage table by metal probe, directly read by the coordinate on template the position of metal probe, and be depicted on corresponding coordinate paper, therefore, in tank, in the tap water dielectric, the potential point of optional position can corresponding retouching out on coordinate paper.

The beneficial effects of the utility model are, in tank in the tap water dielectric electromotive force of optional position measure to be shown by voltage table by metal probe, directly read by the coordinate on template the position of metal probe, thoroughly solved the not problem on same straight line of double-decker instrument middle probe and tracing point, make and describe to become directly perceived and simple, and conducting medium, electrode are easily changed and clean.

Description of drawings

Below in conjunction with drawings and Examples, the utility model is further illustrated.
