Abstract

The invention relates to power transmission equipment monitoring technologies, in particular to a power transformation equipment comprehensive state wireless monitoring system based on passive sensing. The problem that an existing power transmission equipment monitoring system is unstable in data transmission, low in data transmission speed, poor in data sharing performance, poor in data collection comprehensiveness, poor in data collection real-time performance, poor in running stability, high in maintenance cost and high in mounting difficulty is solved. The power transformation equipment comprehensive state wireless monitoring system based on passive sensing comprises a capacitive electric field energy collecting device, a rectifier, a DC / DC convertor, SAW oil quality sensors, high-voltage charged sensors, wireless data collectors, a substation IED, a substation CAC, a monitoring host, a database server, a locking controller, a computer key, a five-prevention master station, a five-prevention lock, a wireless universal serial bus, a CAN bus and an infrared ray channel. The system is suitable for monitoring power transformation equipment.

Description

technical field [0001] The invention relates to the monitoring technology of substation equipment, in particular to a wireless monitoring system for comprehensive status of substation equipment based on passive sensing. Background technique [0002] As an important part of the power grid, whether the substation equipment can operate reliably and safely is directly related to the reliability and safety of the power grid operation. Therefore, in order to ensure the reliability and safety of the power grid operation, the substation equipment monitoring system is mainly used to monitor the comprehensive status of the substation equipment. Under the existing technical conditions, the substation equipment monitoring system has the following problems due to its own structure: First, the existing substation equipment monitoring system generally lacks a reasonable network topology structure, which leads to the problem of unstable data transmission. This directly affects the reliabil...
