Multi-factor phase color tube aging simulation experiment method

Abstract

The invention relates to a multi-factor phase color tube aging simulation experiment method. The multi-factor phase color tube aging simulation experiment method includes the steps that step 1, an experiment box which is provided with a heating system, a chemical etching system, a radiation system, a high voltage electrode and a data detection system is prepared; step 2, a cylindrical accessory phase color tube is placed in an inner chamber of a box body; step 3, the temperature of the inner chamber of the box body is within the range of 25 to 2500 DEG C and the humidity of the inner chamber of the box body is within the range of 0 to 10%; step 4, the chemical etching liquid is injected into the inner chamber of the box body through the chemical etching system; step 5, the 2 to 20 kV alternating current voltage is switched into the inner chamber of the box body through the high voltage electrode; step 6, the radiation system is opened in the inner chamber of the box body to form a multi-factor simulation environment. According to the multi-factor phase color tube aging simulation experiment method, multiple factors such as the chemical etching, the electricity, the heat and the ultraviolet and the combined action which cause the aging of the phase color tube are effectively evaluated and accordingly the reliability of experiment data is improved and meanwhile the aging time is effectively shortened and a simulation device is close to the actual operation situation of a transformer in comparison with a single-factor heat aging or electrical aging method and device.

Description

technical field [0001] The invention belongs to the field of electric power detection equipment, in particular to a multi-factor phase color tube aging simulation experiment method. Background technique [0002] The aging and fading of the phase color tube is mainly due to the external factors such as long-term heat, oxygen, light, mechanical force, radiation, chemical medium, ozone in the air, etc., which cause chemical changes in the macromolecular chain and destroy the original rubber. Chemical structure, which leads to deterioration of the performance of the phase color tube. Phase color tubes with different components have different effects on various factors under different conditions of use, and their aging conditions are also different. Even for the same product, the aging condition is different due to the different seasons and regions of use. Chromatographic tube aging is a comprehensive chemical reaction caused by many factors. The aging process of phase color t...
