Problems solved by technology

[0003] At present, most high-voltage discharge demonstration systems use capacitor charging and discharging for demonstration. The arc cannot be maintained, so it cannot simulate the real arc discharge phenomenon, and the capacitor needs to be equipped with a complete discharge circuit to avoid damage t

Abstract

The invention relates to a high-voltage discharge demonstration system and method. The system comprises a touch integrated operation table, a voltage regulator, a boosting transformer, a simulation high-voltage wire, an arcing device, an arc blowing device and a grounded resistor; the voltage regulator is connected with the touch integrated operation table; the voltage regulator is connected with the voltage regulator; the simulation high-voltage wire is connected with the boosting transformer, and a discharge ball is arranged in the middle of a single phase of the simulation high-voltage wire; the arcing device comprises a push rod and a small ball arranged at the top end of the push rod, and the push rod is connected with the touch integrated operation table; the arc blowing device is connected with the touch integrated operation table; and the grounded resistor is connected with the small ball. By means of the method of the high-voltage discharge demonstration system, the high-voltage discharge phenomenon can be truly restored, and a student can personally experience the significance of the high-voltage safety distance; meanwhile, arcs are formed through the arcing device, and the injuries of high-temperature burns of the arcs can be visually observed. The system and the method are visual in effect, simple in device, novel in method and good in teaching treatment effect.

Description

technical field [0001] The invention relates to a high-voltage discharge demonstration system and method, in particular to a demonstration system and method for simulating the discharge of a high-voltage electrified body to the ground when the safety distance is insufficient in a high-voltage environment. Background technique [0002] The minimum distance to be kept between a person and a charged body, between a charged body and a charged body, between a charged body and the ground, between a charged body and other facilities, is also called a safety distance. The safety distance should ensure that no flashover discharge occurs under the action of various possible maximum working voltages or overvoltages, and it should also ensure the absolute safety of the staff when inspecting, operating, maintaining and overhauling electrical equipment. The safety distance is used not only to prevent the human body from touching or getting too close to the charged body and causing electri...
