Abstract

The invention discloses a transformer oil degradation test system. The transformer oil degradation test system comprises a test oil tank, an oil conservator, an oil filter, an oil pump, a vacuum machine, a respirator, a heater, a temperature sensor, a temperature control unit, a test electrode, a gas dissolving device, a gas cylinder and an oil dissolved gas component detection device connected with the test oil tank, wherein the oil conservator is connected with the top of the test oil tank through a pipeline; the vacuum machine and the respirator are connected with the top of the oil conservator through pipelines; the oil pump is connected to the bottom of the test oil tank through a pipeline; the oil filter is connected to the bottom of the oil conservator through a pipeline; the heateris mounted inside the test oil tank; the temperature sensor is mounted on the surface of the heater; the gas cylinder is connected to the gas dissolving device through a pipeline; the gas dissolvingdevice is connected with the test oil tank through a pipeline. The transformer oil degradation test system provided by the invention can effectively test the aging decomposition characteristics of insulating oil and the effectiveness of detection of degradation decomposition products of transformer oil. The invention further provides a transformer oil degradation test method.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to a transformer oil degradation test system. Background technique [0002] The power transformer is one of the most important equipment in the power system, and its operational reliability is directly related to the safe and stable operation of the power system. During the operation of large oil-immersed power transformers, due to the combined effects of heat, electricity, and chemicals for a long time, the insulating paper and transformer oil in the oil-paper insulation system will gradually age over time, and produce such as methane, ethane, etc. The aging products of alkane, ethylene, acetylene and micro-water, etc., lead to a gradual decline in its own insulation performance, resulting in transformer failure. Therefore, accurate diagnosis of the insulation state of the oil-paper insulation system is crucial to the safe operation of the transformer, and it is also the prem...
