Abstract

The invention provides a fault gas production pressure simulation test device for oil-less equipment. The simulation test device comprises a sealing body and an oil conservator. The oil conservator isarranged above the sealing body, the oil conservator is communicated with the sealing body, the sealing body is used for simulating oil-less equipment, and the oil conservator is used for storing oiland supplementing oil to the sealing body; a plurality of gas injection holes are formed in the sealing body and used for being connected with gas injection equipment to inject fault simulation gas into the sealing body; a pressure sensor is further arranged in the sealing body and used for detecting pressure in the sealing body so as to detect pressure changes in the sealing body at different gas injection rates under different fault simulation gas. According to the invention, pressure simulation is carried out on fault gas production of oil-less equipment; the internal pressure condition ofthe equipment is monitored in real time, the pressure value detected by a simulation experiment is obtained by simulating gas with different fault characteristics, the change relationship between thepressure and the time is analyzed, and the threshold value of fault early warning is determined and further serves as the reference value for fault alarm of the oil-less equipment.

Description

technical field [0001] The invention relates to the technical field of electric power equipment, in particular to a gas production pressure simulation test device for oil-less equipment failure. Background technique [0002] Gas production pressure simulation detection for oil-less equipment failure is mainly for equipment with less oil volume, such as bushings and transformers. After such equipment fails or has defects, the pressure changes significantly. Through pressure testing, it can be judged whether the equipment has occurred. Fault; when the pressure threshold is too high, the timing of the fault cannot be accurately and punctually detected. Late detection timing may lead to explosion or fire of oil-poor equipment, resulting in unsafe conditions. For oil-poor equipment, the pressure threshold is too small, and misoperation may occur. That is, the oil-poor equipment does not fail, but the test result is diagnosed as a failure leading to misoperation. Contents of the...
