Description

Technical Field

[0001] The invention relates to the technical field of track contact network, and in particular to a contact network line test safety early warning device and system. Background Art

[0002] With the rapid development of economy, the pace of urbanization is gradually accelerating, and urban transportation is becoming more and more worthy of consideration. Among them, the power supply system is an important part of urban rail transit. The reliable and safe power supply of the power supply system ensures the normal operation of the subway. The subway power supply system consists of two parts: one is the high-voltage power supply system (external power supply), that is, the urban power grid, which often has three power supply modes: centralized, decentralized and hybrid; the other is the subway internal power supply system, which is composed of the traction power supply system and the power lighting power supply system. The three-phase high-voltage AC provided by the traction substation is rectified into low-voltage DC suitable for subway vehicles. The feeder then sends the DC to the subway contact network for use by subway vehicles. At the same time, it is also necessary to provide power supply for various power mechanical equipment such as lighting, escalators, fans, water pumps, and communication, signal, automation and other equipment in stations and sections. In addition, the power monitoring system (SCADA) responsible for monitoring, controlling and collecting data on the operating status of power supply equipment also belongs to the scope of the subway power supply system.

[0003] The urban rail transit power supply system is the source of electricity for all electricity users in the subway, and is the power guarantee for the operation of subway trains and electromechanical systems. Its reliability is directly related to the safety and stability of the subway system. With the continuous increase of urban rail lines in my country, the complexity of its power supply system is also increasing. The probability of subway accidents, the scope of failures, and the losses caused are also increasing. Once a subway contact network fails, it will lead to the interruption of subway operations and cause significant economic losses. Therefore, real-time detection of key nodes of the contact network is very necessary. During use, due to long-term use and wear, line failures and line gaps occur, but this will cause safety hazards, and this hazard will greatly increase the safety of the train and endanger the safety of passengers.
