The fan control box is installed in the cell nearby, deploys 7 altogether: 2 main control buildings are installed, 4 35kV fields are installed, and 1 500kV field is installed; and 1 water pump control box is installed nearby at the water pump at the south side of the main control building. The air conditioner controller is connected with the 485 local module nearby, and the fan and the water pump are controlled to be connected with the general local module nearby.

Primary equipment on-line monitoring system: the on-line monitoring subsystem is composed of various on-line monitoring devices, on-line monitoring local modules and the like, on-line monitoring information is accessed into the substation auxiliary equipment monitoring system through the on-line monitoring special local module, and acquisition, transmission, background processing, storage and forwarding of on-line monitoring state data are achieved.

All on-line monitoring information of the station end needs to be accessed to the Nanrui intelligent auxiliary platform and uploaded to the central platform;

adding local modules in the second area, wherein each online monitoring system is accessed to the local modules through a protocol and uploaded to a second-area server at a station end through a second-area network;

safety tool management system

The intelligent safety tool cabinet is connected into the station auxiliary equipment centralized monitoring system, and the centralized monitoring of the auxiliary control background on the safety tool information is realized.

(1) An intelligent safety tool cabinet is installed in a transformer substation, so that intelligent management of safety tools in the substation is realized

(2) The intelligent safety tool cabinet is directly accessed to a II area network through a switchboard, and is communicated with an auxiliary control equipment monitoring host through a DL/T860, and the communication content comprises tool state information, warehouse entry and exit information, tool use information and the like;

(3) and the centralized monitoring system for the auxiliary equipment in the station is additionally provided with a tool state monitoring module, so that the centralized monitoring of the auxiliary control background on the information of the safety tools is realized.

The intelligent monitoring system fully applies modern information technologies such as artificial intelligence, mobile interconnection, big data and cloud computing, realizes the functions of equipment interconnection, man-machine interaction, comprehensive state sensing, efficient information processing and convenient and flexible application, further improves the equipment sensing capability, defect discovery capability, state control capability, active early warning capability and emergency handling capability of operation and maintenance personnel, comprehensively strengthens the operation and maintenance management of unmanned/few-person on-duty transformer substations, improves the timeliness and pertinence of operation and maintenance, and provides powerful technical support for safe and stable operation of power grids and equipment in the transformer substations. Based on the above, the invention has good application prospect.
