On-line detection and operation maintenance system of transformer station

Abstract

The invention relates to the field of electrical equipment and aims at providing an on-line detection and operation maintenance system of transformer stations, which has good real-time performance, remote detection function and high intelligence degree. The on-line detection and running maintenance system comprises information acquirers used for acquiring various operation data of all transformer stations, information collectors arranged on all transformer stations, an operation maintenance server and an on-duty computer terminal, wherein the operation maintenance server is in communicated connection with the information collectors of all the transformer stations; the information collectors and the information acquirers are in communicated connection in a 485 manner; and the operation maintenance server is in communicated connection with the on-duty computer terminal through an internet. The on-line detection and operation maintenance system automatically detects power-loss faults and phase-loss faults of all detection points of all the transformer stations, gives an alarm through a wireless network, reduces the fault maintenance time, and improves the power supply quality.

Description

technical field [0001] The invention relates to the field of power equipment, more specifically, the invention relates to a substation online detection and operation maintenance system for wireless communication and automatic management. Background technique [0002] At present, traditional substations are supervised on-site by special personnel on duty or regular inspections, which have poor real-time performance and no remote detection function; once a failure or other abnormal situation occurs, it is impossible to respond immediately. With the development of radio communication technology and automation management technology, the operation status and fault conditions of each substation are centrally detected and maintained through the wireless network; a small amount of investment can greatly improve the operation reliability of each substation and shorten the failure time. [0003] The Chinese Patent Office published a CN101030710A document on September 5, 2007, which is...

AI Technical Summary

Problems solved by technology

The disadvantage of this system is that it does not detect and alarm the faults of the power system itself in the substation, and this is the content that occurs most often and needs to be detected and alarmed the most.
