Abstract
The utility model relates to a teaching instrument, particularly a step voltage experimental device used for physical teaching. The utility model is mainly composed of binding posts (1), (7), a washer (5), an outer ring (3), circular conducting paper (6), etc., wherein the binding post (7) switches into conduction with the outer ring (3) which switches into conduction with the conducting paper (6), and the conducting paper (6) switches into conduction with the washer (5) which switches into conduction with the binding post (1). Only the alternating current voltage of about 6V-10V is added between the two binding posts, and at this time, the analog step voltage can be measured on the conducting paper through an alternating current gear of a teaching demonstrating electric meter. The utility model has the advantages of convenient operation, favorable demonstrating effect, etc.
Description
Affiliated technical field
The utility model relates to a kind of instruments used for education, the step voltage tester of using on especially a kind of physics teaching.
Background technology
When a live line of high voltage overhead lines is disconnected when dropping on the ground,, just there is step voltage between the bipod if people's bipod stands near the different position of landing the electric wire.This is a content that will relate in the physics teaching in secondary school.It is unrealistic that but teacher will do this experiment on class on the spot, understands the teaching and experiment equipment that does not also have this respect at present according to me.
Summary of the invention
The purpose of this utility model provides a kind of experimental apparatus that can demonstrate step voltage.
The utility model is achieved like this: it simulates ground with the conductive paper of a circle, the center and the periphery of circular conductive paper are connected with binding post, by binding post when the center of conductive paper and periphery add alternating voltage about 6V-10V, just can measure the step voltage of simulation with the teaching ammeter on conductive paper, two test pencils of teaching this moment ammeter just are equivalent to people's bipod.Owing to adopted this programme, the utlity model has advantages such as easy to operate, good demonstration effect.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is a structural representation of the present utility model.
(1), power connecting column (2), substrate (3), outer ring (4), screw (5), packing ring (6), conductive paper (7), power connecting column among the figure.
Embodiment
With the conductive paper of circle, with dashed lines draws some equidistant concentric circless in the above, makes a call to an aperture at the center of conductive paper again, passes substrate (substrate can be made with plastics or wood) and conductive paper from bottom to top with screw again.On screw, put packing ring made of copper again, on screw, load onto binding post (1) then.The outer ring of making of a copper sheet is pressed on the periphery of conductive paper again, makes it to contact well with conductive paper with nail or the fastening good outer ring of screw again, loads onto binding post (7) again on the outer ring.Add the alternating voltage about 6V-10V during demonstration on two binding posts, this moment is with regard to the step voltage of interchange shelves measure analog on conductive paper of available teaching ammeter.Two test pencils of teaching ammeter just are equivalent to people's bipod.
Claims (2)
1, a kind of step voltage tester, it is mainly by binding post (1) (7), packing ring (5), outer ring (3) and conductive paper formations such as (6), wherein binding post (7) and outer ring (3) conducting, outer ring (3) and conductive paper (6) conducting, conductive paper (6) and packing ring (5) conducting, packing ring (5) and binding post (1) conducting is characterized in that: circular conductive paper, and with dashed lines has been drawn some equidistant concentric circless on conductive paper.
2, step voltage tester according to claim 1 is characterized in that: its center of circular conductive paper is connected with binding post (1) by packing ring, and the periphery of circular conductive paper is connected with binding post (7) by the outer ring.
