Problems solved by technology
However, due to the safety reasons of high-voltage live equipment such as transformers, the actual operation training and assessment of live equipment cannot be realized. It is difficult to remove various impurities in the oil under normal pressure, and the prepared oil samples cannot accurately simulate various fault gas components and contents. time constant save
At present, there is a lack of a device and method that can fully fit various faulty oil samples in the actual operation of the transformer and can simulate the operation of transformer oil sample collection

Abstract
The invention relates to a preparing and collecting device and a preparing and collecting method for an oil sample of an analogue transformer. By manually matching a main oil tank, an adjusting oil tank and an auxiliary oil tank, transformer oil of multiple typical transformers in a failure state can be accurately produced; various characteristic gas components and contents in oil can be accurately controlled and can be preserved at normal temperature at a constant value. The device provides multiple parallel stations, can completely simulate actual collecting process of the oil sample of the transformer, and can be safely and conveniently used for works such as skill training, examination, technological competition and the like of professional practitioners for oil chemical examination, electrical test / examination and the like; the device is low in application cost, safe in operation, high in integrating degree with field operation, convenient and quick; transformer oil adopts a mode of reutilization and purifying, and recycling, so economy and environmental protection are realized.
Description
technical field [0001] The invention relates to a device and method for preparing and collecting samples of simulated transformer oil, and also relates to a method for using the device to prepare and collect samples of simulated transformer oil. Background technique [0002] During the operation of oil-filled electrical equipment such as transformers, different fault states will produce different characteristic gases (mainly including CH 4 、C 2 h 6 、C 2 h 4 、C 2 h 2 , CO, CO 2 、H 2 etc.), and dissolved in insulating oil. Accurate analysis of the characteristic gas components and content of dissolved gas in insulating oil can judge the safety status of equipment and discover early latent faults, which is one of the most effective measures to monitor the safe operation of oil-filled electrical equipment; [0003] Because the dissolved gas content in oil will change with the temperature, pressure and sealing state of the oil, the whole process of collecting oil samples...
