Abstract

The invention discloses a virtual experiment system and method for simulating non-uniform electric field breakdown voltage. The system includes a tip-flat panel module, a voltage module and a breakdown display module. The voltage module includes a PC module and a voltage regulation module , a judging module and a display module. The method includes the following steps: 1. Construct a corresponding two-dimensional relationship table and input it into the system for calling at any time during system operation; 2. Initialize the system, run the Jijian-flat module to generate a virtual electric field; 3. Run The voltage regulation module gradually increases the voltage; 4. The operating voltage module; 5. The operating judgment module; 6. The operating breakdown display module displays the virtual breakdown process. The invention does not need to invest in physical high voltage and its supporting equipment, and is economical; the remote experiment is flexible enough, which can not only ensure the safety of the experiment, but also get rid of the restrictions of the experimental site, the high voltage level of the physical equipment, and the insulation requirements.

Description

technical field [0001] The invention belongs to the field of power system automation, and in particular relates to a virtual experiment system and method for simulating non-uniform electric field breakdown voltage. Background technique [0002] The power system includes a lot of electrical equipment, and the failure of some electrical equipment will threaten the power supply security of the entire system. To this end, it is necessary to carry out testing and testing work on electrical equipment in accordance with regulations to ensure the safe operation of the power system. Electronic devices have a maximum withstand voltage value that exceeds the allowable value, and the device has a risk of failure, and the component will be scrapped. Breakdown is the phenomenon of violent discharge or conduction of insulating materials under the action of voltage. [0003] There are currently existing technical literature on the experimental method and research of high-voltage virtual c...
