Simulation experiment device and method

Abstract

The invention discloses a simulation experiment device and method. The primary side of the single-phase power frequency experiment transformer is connected to a power frequency mains supply through anair protection switch. One end of the secondary side of the single-phase power frequency experiment transformer is connected with an output double-touch switch; the output double-touch switch is divided into two paths, one path is connected with an experiment box through a rectifying device and a voltmeter, the other path is directly connected with the voltmeter and the experiment box, and the other end of the secondary side of the single-phase power frequency experiment transformer is connected with the voltmeter and the experiment box through the protective resistor and the ampere meter insequence; the power frequency mains supply supplies power to the experiment box; the controllable temperature of the experiment box is room temperature to 600 DEG C, and the experiment box is used forproviding a constant-temperature and constant-atmosphere experiment environment for the sample to be detected. According to the invention, actual operation conditions of electrical materials or devices can be simulated, and various experiment tests can be carried out.

Description

technical field [0001] The invention belongs to the technical field of electrical materials and device experiments, and in particular relates to a simulation experiment device and method. Background technique [0002] Electrical materials and devices are widely used in energy, communication, transportation and other important fields involving the lifeline of the national economy. Their operating conditions are complex, and it is the joint responsibility of designers and operation and maintenance personnel to ensure their safe and stable operation. Since electrical materials or devices are usually in a harsh environment of high electric field, high temperature, non-standard atmospheric pressure or low oxygen concentration during operation, their insulating properties are related to their service life, while pyrolysis and combustion properties determine whether they will cause major vicious fires And explosion accidents, even directly endangering people's lives and property sa...

AI Technical Summary

Problems solved by technology

[0005] At home and abroad, there are few experimental devices and research methods for electric, electronic materials or devices in complex environments such as high electric field, high temperature, non-standard atmospheric pressure or low oxygen concentration.

Many high-voltage experiment standards and test methods do not take into account the actual operating conditions of electric power, electronic materials or devices, resulting in unreliable test results

[0006] Since most electrical materials or devices need to withstand high field strength, the existing experimental devices cannot meet their harsh and complex operating environments.
