Abstract

The invention discloses an intelligent insulator for an electric rail traffic traction power supply system. The intelligent insulator comprises an insulator body, one end of the insulator body is provided with a lower accessory, the inner wall of the lower accessory is provided with a pressure sensor, an outer protective sleeve is arranged between a skirt of the insulator body and the lower accessory, a leakage current collection ring is arranged on the outer protective sleeve in a sleeved mode, and the leakage current collection ring and the pressure sensor are respectively connected with a lead. The intelligent insulator has the advantages that online quality monitoring and visualization quality report are achieved, quality accidents, caused by insulation devices, of the electric traction power supply system are warned in advance, intelligentization of the insulation devices for the electric rail traffic traction power supply system is achieved, and safety and stability of the electric rail traffic traction power supply system are guaranteed.

Description

technical field [0001] The invention relates to a series of insulating equipment for traction power supply systems of electrified rail transit. It mainly invents a kind of insulation equipment with excellent electromechanical performance and can realize online quality monitoring. Specifically, it is a series of intelligent porcelain composite insulators for traction power supply systems of electrified rail transit. Background technique [0002] The national "medium and long-term railway network plan" proposes that by 2020, the national railway operating mileage will reach 100,000 kilometers, the double-tracking rate and electrification rate will both reach 50%, and the main technical equipment will reach or approach the international advanced level. The national economic and social development plan has vigorously promoted urbanization, the urban population has increased sharply, and traffic has been seriously blocked. Therefore, my country's urban rail transit construction ha...
