Problems solved by technology

[0003] However, due to the high price of the high-voltage electrical experiment equipment, the high risk of the experiment, and the inconvenient control, it is difficult to popularize the experimental equipment and carry out related experiments. Therefore, many students often can only obtain it by watching videos or in science and technology exhibition halls. The relevant practical knowledge of high-voltage electricity often does not have an intuitive impression of the phenomenon of high-voltage discharge, and I have no chance to practice it
Theory and practice are not well integrated

Embodiment Construction

[0022] The component box contains the following components: 12 high-voltage capacitors (C), 24 discharge balls (G), 1 copper wire with insulated sheath, 4 connecting wires, 2 discharge copper wires, 2 bracket bases (Z1), Two retractable metal rods (Z4), two output terminals (Z5), four hex nuts (Z7), one power cord, and one iron wrench.

[0023] When plugging in and turning on the power supply, the main transformer converts the 220V city power into 24V AC power, and then converts it into DC power through the rectification and filtering circuit behind and sends it to the booster circuit.

[0024] The boost element used in the boost circuit is the line output transformer. When the switch K1 is closed, the F2 pin of the horizontal output transformer F is connected to a 24V, 1.5A DC power supply, and the current flows from the F2 pin to the F1 pin. When it is grounded, the potential becomes 0, and a large induced electromotive force in the opposite direction to the original will b...

Abstract

The invention relates to a high-tension electrical experimental box that can be used as high voltage experimental installation or teaching demonstration equipment, belonging to the technical field of education teaching instrument. A plurality of different alternating current / direct current high-tension discharge experiments can be carried out by using the experimental box, such as alternating current high-tension discharge, direct current high-tension continuous discharge, pulse high-tension discharge, high-tension arc ignition experiment, Tesla coil discharge experiment; moreover, the experimental box can be used as a controlled plant, and other experiments are carried out by self-designing. Aiming at the current situation of being lack of experiment opportunity of related disciplines in colleges and universities, the use of the experimental box can play a supplementary role for theoretical teaching. The device has low cost and simple use method, is relatively safe and suitable for being used widely.

Description

technical field [0001] The invention relates to a device for college students to conduct electrical experiments or teaching demonstrations, especially for high-voltage electrical experiments. Background technique [0002] my country's ongoing construction of high-voltage and ultra-high-voltage related projects, research on high-voltage high-power power supplies and AC-DC high-voltage characteristics, etc., there are many technical problems to be solved, including system research, testing, product research and development, engineering design and implementation and other issues. As well as research on the electromagnetic environment, overvoltage and insulation coordination, DC bias, control and protection systems, and AC-DC high voltage characteristics of high-voltage and UHV DC transmission projects, the practical ability of scientific researchers in the high-voltage field has been raised. higher requirement. [0003] However, due to the high price of high-voltage electrical e...
