Problems solved by technology

The devices in the cabinet cannot meet the interoperability and interchangeability requirements of the smart devices in the smart substation
In addition, the information of the online detection cabinet must be uploaded to the background of the substation through a private protocol and a large number of control cables. The anti-interference ability of the communication signal is poor, and the maintenance is difficult. The operating environment of each device in the cabinet is not easy to control and monitor, and there is a certain degree of security. Hidden danger

Abstract

The invention discloses an intelligent component cabinet and a monitoring method for an intelligent transformer. Intelligent electronic equipment is installed in the intelligent component cabinet and comprises a measuring IED, a cooler controlling IED, a load voltage adjusting IED, an in-oil dissolved gas and micro water monitoring IED, a partial discharging monitoring IED, a light winding temperature detecting IED, a reactor magnetic leakage and partial overheating monitoring IED, a reactor iron core cake vibration monitoring IED, a combining unit, a non electricity protecting IED and a main IED. Sensors adopted by the IED acquire transformer operation, control and reliable state information and combines unit current signals, and an intelligent component processes the acquired data, forms integral intelligent result information and transmits to a station control layer network by a communication protocol DL / T860; information support is provided to transformer monitoring and intelligent control, power grid operation optimization and transformer maintenance strategy optimization, and the electromagnetic interference resistance and high voltage resistance of electronic products in intelligent component cabinet and transformer combined tests are improved.

Description

technical field [0001] The invention belongs to the technical field of intelligent control equipment, and in particular relates to an intelligent component cabinet and a monitoring method for an intelligent transformer, which are widely used in intelligent substations or digital substations. Background technique [0002] In traditional substations, the terminal boxes, instrument terminal boxes, control cabinets, on-line detection cabinets, and intelligent terminal cabinets used with the transformer are scattered around the transformer, and the number of cabinets is large and scattered. The devices in the cabinet cannot meet the interoperability and interchangeability requirements of the smart devices in the smart substation. In addition, the information of the online detection cabinet must be uploaded to the background of the substation through a private protocol and a large number of control cables. The anti-interference ability of the communication signal is poor, and the ...
