Transformer electrical fault gas simulation device

Abstract

The invention discloses a transformer electrical fault gas simulation device, and relates to the field of the transformer fault diagnosis. The device comprises a tank body, a pressure balance releasing device, a temporary storage tank and a tee valve arranged at the top of the tank body; the tee valve is located at the top of the tank body, the tee valve is used for connecting the tank body, the pressure balance releasing device and the temporary storage device or any two of them; an electrode system for applying the electric field is arranged in the tank body, and the electrode layer comprises a high-voltage electrode and a ground electrode. The device can be used for electric fault simulation of the transformer to guarantee that the test process is completely isolated from the atmosphereinterference and the simulation test of different insulation mediums and different electric fields can be performed under the same test environment. The device provides basic reference data for gas dissolved in oil analysis of the novel transformer oil, thereby prejudging whether fault potential is existent when the novel transformer oil transformer is in operation through the gas dissolved in oil analysis technology, and quickly diagnosing the fault reason after the fault occurs.

Description

technical field [0001] The invention relates to the field of transformer fault diagnosis, in particular to a fault diagnosis simulation device for dissolved gas in transformer oil. Background technique [0002] The transformer is one of the most important equipment in the power system. Once a fault occurs, it will cause a power outage and cause huge losses. How to predict the fault of the transformer before the fault occurs, and quickly determine the cause of the fault of the transformer after the fault occurs. safe operation is crucial. At present, the most widely used transformers in the power industry, the largest capacity, and the highest voltage level transformers are oil-immersed transformers, which have excellent performance, low cost, stable operation, and easy recycling, occupying the mainstream of the current transformer industry. [0003] The windings, iron core, body insulation and other components of oil-immersed transformers are all immersed in transformer oil...

Problems solved by technology

However, for new insulating oils, such as natural esters, synthetic esters, silicone oils, macromolecular hydrocarbons and other insulating oils, their composition is different from traditional mineral insulating oils, resulting in differences in dissolved gases in different insulating oils under the same electrical fault, and Due to the small number of applications, it is difficult to obtain a large amount of application data, resulting in the immature analysis technology of dissolved gas in oil for new insulating oils. Therefore, it is necessary to simulate its fault state under laboratory conditions to obtain basic judgment criteria. Have a basis and correct it in future transformer fault diagnosis
