Abstract

The invention discloses a traction transformer layered oilpaper insulation dielectric response experiment system comprising a transformer oil tank, a layered insulation system disposed in an experiment box body, a connecting device (an oil pump, a plastic hose and multi-pipe joints) of the transformer oil tank and the experiment box body, a dielectric response tester, and a control and data acquisition system. The experiment system of the invention can be used for simulating non-uniform heat aging in an actual traction transformer oilpaper insulation system and researching the dielectric response characteristic of the oilpaper insulation of non-uniform heat aging, and can help to research remaining life evaluation of the oilpaper insulation with non-uniform heat aging distribution.

Description

Technical field [0001] The invention belongs to the field of transformer insulation state detection, and specifically relates to a traction transformer layered oil-paper insulation dielectric response experimental system. Background technique [0002] 2015 National Government Work Report of the Two Sessions: my country's high-speed railway operating mileage has exceeded 16,000 kilometers, exceeding the total mileage of high-speed railways in other countries. At the same time, China's high-speed rail going overseas has risen to the height of national strategy. The service life and reliability of equipment are important factors for the long-term safe operation of my country's high-speed railways and the successful implementation of the "high-speed rail going global" strategy. Traction transformers are the core power supply equipment for high-speed railways, and their effective service life and life management have attracted widespread attention in the industry. However, at present...
