Problems solved by technology

[0003] At present, in the existing technology, whether it is the development of testing instruments, operation failure testing, and training of technicians, it is necessary to carry out SF6 micro-water testing and training of high-voltage equipment through real physical equipment. This method and device have inherent insurmountable Problems, such as: In the existing technology, real SF6 micro-water testers are required for testing technology training, but the tester cannot be equipped for everyone, and remote network training cannot be realized, which limits the development of training; the comparison of testing instruments Sensitive, it is easy to cause equipment damage due to improper operation by the user; the detection device needs to be equipped with the equipment under test (and equipped with various high-pressure SF6 gas equipment to be measured), occupying a large amount of space and facilities, and the investment cost of this method is very expensive (for example, a The cost of 220kV circuit breaker equipment is more than 100,000 yuan), and the safety is difficult to guarantee; due to the limited conditions, it is difficult for the general training venue to simulate the real background of the scene, and the simulation effect is very unsatisfactory; When testing and training, it is still necessary to go to the real equipment on site to test and obtain data
[0004] In summary, the traditional SF6 gas high-voltage equipment simulation test method for micro-water charging has been unable to meet the increasing demand for power system visualization

Description

Technical field [0001] The invention relates to power system simulation technology, in particular to a visual simulation test method for micro-water charging of SF6 gas high-voltage equipment. Background technique [0002] SF6 electrical equipment is one of the key equipment of the power system. SF6 micro-water analysis is a necessary test item for the delivery test of this kind of electrical equipment, the preventive test during operation, and the handover test before the capital construction project is put into operation. Therefore, it is extremely necessary to develop electrical equipment SF6 micro-water live test equipment, SF6 micro-water detection during equipment operation, and training of technical personnel in scientific research institutions, power systems, and large-scale user substations (such as subways, airports, etc.). The above work is inseparable from the SF6 micro-water charged test instrument. Good, lifelike SF6 micro-water live test instrument is an importan...
