Description

Technical Field

[0001] The present invention relates to the field of wireless mobile monitoring technology, and in particular to a wireless intelligent monitoring device for a contact network switch station. Background Art

[0002] In the electrified railway traction power supply system, the 220kV / 110kV three-phase AC power supply from the power system is converted into a 27.5kV single-phase power supply through the traction transformer installed in the traction substation, and is connected to the high-voltage busbar in the substation. Then, it supplies power to the traction network through the feeder circuit breakers and disconnectors. In order to facilitate fault removal, multiple disconnectors are also installed along the traction network to divide the traction network into multiple power supply zones. The up and down lines of the traction network of a power supply arm of the traction substation are gathered at the zone station. Through disconnectors and circuit breakers, the ends of the up and down lines of the traction network can be connected in parallel.

[0003] Traction substation feeder disconnectors and substation incoming line disconnectors are managed by their respective integrated automation systems, while traction network line disconnectors are managed by the overhead contactor disconnector monitoring system. The overhead contactor disconnector monitoring system is divided into fiber-optic and direct-drive types. Currently, the direct-drive type is predominant, generally referred to as a direct-drive overhead contactor centralized monitoring system. Conventional direct-drive overhead contactor centralized monitoring systems utilize telecontrol by the power dispatching system, which presents the following deficiencies during installation, commissioning, and operation: 1) During system installation and commissioning, telecontrol conditions are generally not available, making it impossible to simultaneously verify the functioning of the telecontrol interface access function of the direct-drive overhead contactor centralized monitoring system, and to simultaneously calibrate the telecontrol point table and other information. 2) During disconnector commissioning, personnel must be on duty at both the substation and the disconnector site, resulting in high staffing and low work efficiency. 3) During normal system operation, if communication interruptions occur, personnel must be dispatched to the site to address the situation, preventing rapid remote diagnosis and emergency response.
