Abstract
The utility model discloses a 0-2000kV lightning flash demonstration device belonging to popular science education instrument, a high-voltage high-frequency oscillator is arranged in housing having universal wheel, an outer sleeve tube insulation post is arranged at the top surface of the housing of the high-voltage high-frequency transformer, the primary winding of the high-voltage high-frequency transformer is the inductance winding of the high-voltage high-frequency oscillator, the auxiliary winding of the high-voltage high-frequency transformer is located in the insulation oil of the outer sleeve tube insulation post and is connected with a press cover. The frequency of discharge current is about at 50-120kHz, the discharge sparkle is bright, under the same discharge clearance, high-frequency breakdown voltage is far lower than the working frequency voltage, under the perfect protection device, the lightning demonstration is very safe and the physical phenomenon of high-voltage discharge of lightning is demonstrated, so as to make the contribution for the popularization and education of the science knowledge.
Description
Technical field
The utility model belongs to Popular Science Education instrument scope, particularly a kind of 0～2000kV lightning apparatus for demonstrating.
Background technology
Many physical phenomenons that nature takes place, along with development of modern science and technology can both be made demonstrating model as propaganda, the education great majority of popular science knowledge, but all thunderous, electricity etc. relate to the physical phenomenon of effluve, are subjected to safe limit and also do not find have this series products to hear generation.
Summary of the invention
The purpose of this utility model provides a kind of 0～2000kV lightning apparatus for demonstrating, form by pressure regulator T, transformer B, full wave bridge rectifier, high voltage high frequency transformer and high voltagehigh frequency oscillator, it is characterized in that: described high voltagehigh frequency oscillator 5 is installed in the shell of belt wheel, outer tube insulation column 3 is fixed on the outer casing top surface of high voltagehigh frequency oscillator 5, primary winding 4 of high voltage high frequency transformer is telefaults of high voltagehigh frequency oscillator 5, the secondary coil 2 of high voltage high frequency transformer is placed in the insulating oil in the outer tube insulation column 3, and and grading shield 1 join.
The insulation double-tube structure that described high voltage high frequency transformer is is skeleton with two sleeve pipe insulation columns, and inject insulating oil.
The beneficial effects of the utility model are to adopt perfect protective device, and are as safe as a house when lightning is demonstrated; The frequency of discharge current is about 50-120KHz, and discharge spark is bright, and high frequency breakdown voltage is far below power-frequency voltage, and safety is secure.
Description of drawings
Fig. 1 is a thunder and lightning apparatus for demonstrating structural representation.
Fig. 2 is thunder and lightning apparatus for demonstrating circuit theory diagrams.
Embodiment
Fig. 1 is a thunder and lightning apparatus for demonstrating structural representation.The high voltagehigh frequency oscillator 5 of this 0～2000kV lightning apparatus for demonstrating is installed in the shell of band universal wheel 6, outer tube insulation column 3 is fixed on the outer casing top surface of high voltagehigh frequency oscillator 5, primary winding 4 of high voltage high frequency transformer is telefaults of high voltagehigh frequency oscillator 5, the secondary coil 2 of high voltage high frequency transformer is placed in the insulating oil in the outer tube insulation column 3, and and grading shield 1 join.The insulation double-tube structure that its high voltage high frequency transformer is is skeleton with two sleeve pipe insulation columns.Universal wheel 6 is arranged, conveniently moving on the shell bottom surface of high voltagehigh frequency oscillator 5.The utility model is used full-wave rectifying circuit and improved the work efficiency of device and perfect protective device, adopts the antiground constant-current device, makes the electric arc of lightning device hit the earth, and is as safe as a house.Components and parts adopt noninductive pulse electrical equipment, can adapt to frequent discharge.The high about 50～120KHz of the frequency of the discharge current of high voltagehigh frequency generator, produce long gap discharge phenomenon, with power frequency, direct current, the impulse high voltage discharge has different characteristics, under equal voltage and discharging gap situation, maximum discharge current is greater than direct current and power-frequency discharge under the high frequency, therefore the discharge spark passage is brighter, under same discharging gap, the voltage breakdown of high frequency is far below power-frequency voltage, the high voltagehigh frequency discharge has the similar nature thunder discharge of its electric discharge phenomena of 2000KV approximately, and its continuity is better than thunder discharge, development that can the repeated observation discharge channel.
Figure 2 shows that thunder and lightning apparatus for demonstrating circuit theory diagrams.Be composed in series the high-frequency spark discharge circuit by pressure regulator T, transformer B, full wave bridge rectifier, high voltagehigh frequency oscillator and high voltage high frequency transformer, a, b are discharging gap among the figure.
