Problems solved by technology

[0004] In the stability test of transformer oil according to industry regulations, the requirements for the flow rate and temperature control of oxidizing gas are relatively high, and the test time is long. The air flow rate and temperature control during the test process is not good, which will affect the accuracy of the test results. Therefore, it is impossible to accurately judge the anti-oxidation performance of oil products
In addition, the efficiency of using manual on-duty for a long test time is not high, and a special oxidation stability test system needs to be designed to liberate manpower

Abstract

The invention relates to the field of petroleum product testing, and provides an oxidation stability testing system which comprises a heating bathing pool, a flow controller, a main temperature controller and a monitoring temperature device. A temperature sensor group connected with the main temperature controller and the monitoring temperature device is arranged in the heating bathing pool; the main control temperature controller is used for setting and maintaining the temperature of the heating bathing pool, and when the temperature exceeds a preset first early warning temperature, the maincontrol temperature controller gives an alarm; the monitoring temperature device is used for monitoring the real-time temperature of the heating bathing pool, and when the temperature exceeds a presetsecond early warning temperature, the monitoring temperature device gives the alarm; and the flow controller is used for controlling the flow of an oxidizing gas introduced into transformer oil. Thesystem is convenient to use and high in safety.

Description

technical field [0001] The invention relates to the field of petroleum product testing, in particular to an oxidation stability testing system and a using method thereof. Background technique [0002] Transformer oil is an important insulating medium for transformers. However, due to oxidation during the use of transformer oil, acidic substances and sludge will inevitably be generated. These acidic substances and oil sludge reduce the insulation and thermal conductivity of the overall equipment, which will affect the safe operation of the transformer, and may even cause serious accidents. [0003] Therefore, oxidation stability is an important quality requirement for transformer oil. The test of the oxidation stability of transformer oil can evaluate the anti-oxidation ability of transformer oil in a friendly way, so as to ensure the safe operation of transformers with transformer oil as the insulating medium. [0004] In the stability test of transformer oil according to ...
