The stake resistance visual simulating method of testing of electrical equipment of the present invention, virtual reality technology is combined with the stake resistance visual simulating measuring technology of electrical equipment, by setting up visual pliers-shape earthing resistance instrument model, calibrating installation model and servicing unit model, can realize visual displaying in the emulation testing process, output data in emulation testing are controlled the error of the resistance value detected by servicing unit, be convenient to evaluate its reliability on the one hand, also strengthened on the other hand the comparability between measurement result; The present invention has greatly improved the visualization of the stake resistance visual simulating test of gas equipment, improved significantly the visualization of human-computer interaction interface in the emulation testing, reduced the processing procedure of emulation testing personnel to numerous and diverse data, accuracy and the work efficiency of emulation testing operation have been improved, meet the power system visualization demand increasingly increased, there is high promotional value.
Emulation testing of the present invention, while having solved pliers-shape earthing resistance instrument error of indication calibrating in the past, flexible circuit conductor can't guarantee to be placed in binding clip geometric center position, and the problem vertical with the pincers circle.Solved when the impact of pliers-shape earthing resistance instrument eccentric position is measured and can't accurately guarantee that flexible circuit conductor is placed in approximate pliers-shape earthing resistance instrument binding clip geometric center position, also can't accurately guarantee to connect flexible circuit conductor and depart from the problem of pliers-shape earthing resistance instrument binding clip geometric center position by the close binding clip inwall in front, rear, left and right.
The present invention passes through virtual ground meter calibrating installation out on computers, can be equipped with a set of calibrating installation without everyone, can save equipment and training cost; Input corresponding data by computer from virtual wiring, just can see realistically the situation of each demonstration part of pliers-shape earthing resistance instrument and calibrating installation thereof, various real pliers-shape earthing resistance instrument and calibrating installation data and line operation etc. that can virtual generation, have overcome the shortcoming that general place is difficult to simulate all devices test data; Having eliminated the ground meter calibrating installation needs certain technical operation, easily because user's misoperation causes the possibility of device damage; Overcome in old calibration method and adopted flexible circuit conductor, the pliers-shape earthing resistance instrument error of indication and eccentric position impact calibrating can not meet the shortcoming of vertification regulation requirement fully; Adopt this method to contribute to especially to realize the telecommunication network training, the needs of realize disperseing training, concentrating examination.
The above embodiment has only expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
