Contact network major loop electrical node overheating on-line monitoring method

Abstract

The invention discloses a contact network major loop electrical node overheating on-line monitoring method. A contact network major loop electrical node overheating on-line monitoring system is adopted, 4G network communication technology and temperature sensing monitoring technology are adopted, and contact network major loop electrical node temperature data collected by a temperature monitoringterminal is transmitted to an information management and alarm back-end system to realize online real-time monitoring of a contact network major loop electrical node temperature state. Via data processing operation performed by the information management and alarm back-end system, advanced early warning can be realized, alarm can be sent out instantly, electrical major loop temperature abnormity points can be found, and electrical connection states and equipment defects can be determined. Basis can be provided for overhauling operation, overhaul plan content can be reasonably made, an intelligentization level and work efficiency of contact network skylight overhaul work can be improved, and safe operation of a contact network major loop can be ensured.

Description

technical field [0001] The invention belongs to the technical field of traction power supply for electrified railways, and relates to an online monitoring method for overheating of electrical nodes of a catenary main circuit. Background technique [0002] It is inevitable that there will be various faults in the catenary equipment of electrified railways. Among them, electrical burns are difficult to predict and cause serious harm before the accident, so they are valued by the electrical operation and maintenance department. According to statistics, there were 135 catenary failures in one year in a power supply section, 48 of which were electrical burns, accounting for 36.3% of the total failures. [0003] Under the condition that the traction capacity is increasing year by year, the temperature of the electrical nodes of the catenary main circuit such as the splicing pipe, pre-twisted clamps and electrical connection clamps is too high, which may lead to burning and burning...
