Abstract

The invention relates to the technical field of science popularization education, and particularly relates to a point discharge demonstration device. The device comprises a table body and a protectivecover arranged on the table body, wherein a high-voltage electrode and a low-voltage electrode are vertically mounted on the table body in the protective cover; a first gear is arranged at the bottomof the low-voltage electrode; a bearing is arranged on the table body on the outer side of the protective cover; one end of the bearing is provided with a hand wheel, the other end of the bearing isprovided with a second gear, a chain is arranged between the first gear and the second gear, the high-voltage electrode is connected with a high-voltage power supply, the low-voltage electrode is connected with a low-voltage power supply, and the high-voltage electrode and the low-voltage electrode are provided with a plurality of metal bars with sharp or spherical ports. The demonstration deviceis suitable for science and technology museum demonstration, and audiences can understand why only the tip is prone to discharge in comparison by observing the discharge between the two tips, the discharge between a tip and a ball and the discharge between the balls.

Description

technical field [0001] The invention relates to the technical field of popular science education, in particular to a cutting-edge discharge demonstration device. Background technique [0002] Point discharge is a kind of discharge phenomenon that occurs on the sharp part of an object under a strong electric field, which belongs to a kind of corona discharge. The charge at the tip of the conductor is particularly dense, and the electric field near the tip is particularly strong, and a tip discharge will occur. The current device used for the demonstration of tip discharge can basically show the phenomenon of tip discharge to the audience, but lacks some exploratory learning, the audience can only observe the discharge phenomenon between the two tips, and cannot demonstrate well except Discharge phenomena other than the tip. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a cutting-edge di...
