Problems solved by technology

The existing intelligent components are composed of more than one intelligent electronic device (IED), including the main IED and each sub-IED, so the sub-IED needs to transmit the signal to the process layer first, and then the main IED extracts the signal from the process layer for comprehensive state analysis. In this way, the main function of each sub-IED is to digitize the signal collected by its front-end sensor, and then transmit it to the process layer, and the process layer returns the data to the main IED for analysis and judgment, which leads to the connection in the component cabinet being very Complicated, the structure of the entire component cabinet is complicated, and the external dimensions are also large, which ultimately makes the layout of the intelligent component cabinet a difficult problem
In addition, the comprehensive functionality of the existing intelligent component cabinets is not strong, and the functions are relatively single, which also limits the applicable occasions of the intelligent component cabinets

Abstract

The invention relates to a cabinet-type comprehensive power transformer intelligent module, and the module comprises a cabinet-type protection housing, an intelligent control terminal, a measurement and control protection terminal module, an in-cabinet constant temperature air conditioning system, a dual-power UPS system, a power distributor, a process level switcher, a station control level switcher and a database server, wherein the intelligent control terminal, the measurement and control protection terminal module, the in-cabinet constant temperature air conditioning system, the dual-power UPS system, the power distributor, the process level switcher, the station control level switcher and the database server are disposed in the cabinet-type protection housing. The measurement and control protection terminal module is connected with the intelligent control terminal through a CAN bus. The in-cabinet constant temperature air conditioning system is connected with the intelligent control terminal through a serial data line. The measurement and control protection terminal module is electrically connected to a sensing measurement device on the main body of a power transformer through the process level switcher and a communication optical fiber. The dual-power UPS system provides power for the module through the power distributor. The intelligent control terminal is in network communication connection with a remote monitoring terminal through a station control level switcher. The module is compact in structure, is complete in function, facilitates the onsite installation and configuration, and is low in cost.
