Visual simulation test method for grounding resistance of electrical equipment

Abstract

The invention provides a visual simulation testing method for a ground resistance of electric equipment. The visual simulation testing method comprises the following steps: establishing a pincer-like ground resistance meter three-dimensional model by using a virtual reality technology; leading in a simulation mathematic model of the pincer-like ground resistance meter three-dimensional model and establishing a corresponding relation between the two models; establishing a detection device three-dimensional model for detecting a pincer-like ground resistance meter by using the virtual reality technology; leading in a simulation mathematic model of the detection device three-dimensional model and establishing a corresponding relation between the two models; establishing an assisting device three-dimensional model used for detecting an indication error and an eccentric position of the pincer-like ground resistance meter by using the virtual reality technology; leading in a simulation mathematic model of the assisting device three-dimensional model and establishing a corresponding relation between the two models; operating a simulation system and calling in the detection device three-dimensional model of the pincer-like ground resistance meter, an instrument three-dimensional model and the assisting device three-dimensional model to carry out visual simulation testing; and controlling an error of a resistance value detected by the assisting device model and outputting the resistance value. According to the visual simulation testing method for the ground resistance of the electric equipment, the accuracy and the working efficiency of the simulation testing are improved and the visual requirements of gradually-increased electric systems are met.

Description

technical field [0001] The invention relates to power system simulation technology, in particular to a grounding resistance visualization simulation testing method of electrical equipment. Background technique [0002] Clamp ground resistance tester, also known as clamp ground resistance tester, is widely used in the ground resistance measurement of electric power, telecommunications, meteorology, oil fields, construction and industrial electrical equipment. It is extremely necessary to carry out the development of grounding resistance testing instruments and the training of technical personnel in scientific and technological research and development institutions, power systems, and large-scale user substations (such as subways, airports, etc.). The above work is inseparable from the clamp ground resistance tester. The good and realistic clamp ground resistance tester is an important tool and means for high voltage equipment fault diagnosis research, operation defect detect...

AI Technical Summary

Problems solved by technology

[0003] At present, in the existing technology, the grounding resistance test and training are carried out through real physical equipment. This method and device have inherent problems that cannot be overcome. Equipped with a real clamp ground resistance tester, but the tester cannot be equipped for everyone, and remote network training cannot be realized, which limits the development of training; the testing instrument is relatively sensitive, and it is easy to cause equipment damage due to improper operation by the user; the testing device needs to be equipped with a Test equipment, occupying a large number of venues and facilities, the cost is huge, and safety is difficult to guarantee; due to limited conditions, it is difficult for ordinary training venues to truly simulate the real background of the scene, and the simulation effect is very unsatisfactory

[0004] In summary, the traditional grounding resistance visualization of electrical equipment has been unable to meet the increasing demand for power system visualization
