Description

A kind of high-tension transformer cooling device monitoring and communication module
Technical field
The utility model belongs to power transformer and detects the control field.Relate to a kind of operating state and carry out online in real time monitoring and the module of communicating by letter, realize Based Intelligent Control the high-tension transformer cooling device with failure condition to the high-tension transformer cooling device.
Background technology
High-tension transformer cooling device control device still adopts the control of contact relay contactor logic systems realizations such as contactor, auxiliary relay and the time relay to cooler input or cut-out mostly at present.Simultaneously cooling device still adopts the cable hard connecting mode with being connected of external device (ED), the function singleness of Shi Xianing not only, and applicability is not strong, and reliability is low, the inconvenience of constructing.We utilize power electronic technology and embedded technology to design a kind of transformer cooling device monitoring and communication module with reference to " power electronic technology ", " design of embedded system ".Host computer can be finished the collection of cooling device blower fan, oil pump state, rotation speed of fan, blower voltage, blower fan electric current, blower fan sky being left information such as state, blower fan oil pump contactor state by this module, and can carry out the start and stop of speed governing and control blower fan and oil pump to blower fan, simplifying circuit connects, save a large amount of cables, satisfy the demand of intelligent grid.Existing transformer cooling device control loop adopts contactor, auxiliary relay and the time relay more, and it installs dispersion, and field connection is many, and applicability is not strong, and reliability is low, and construction is inconvenient.
Summary of the invention
The purpose of this utility model is to provide a kind of high-tension transformer cooling device monitoring and communication module, this utility model is simplified existing cooling device control loop, adapts to the requirement of intelligent grid: measure digitlization, Control Networkization, status visualization, function integration, information interactionization.Reduce field connection, allow rotation speed of fan adjustable simultaneously, realize energy-conservation and noise reduction.
The technical solution of the utility model is achieved in that
Comprise three parts, a part of light-coupled isolation is connected with the CPLD processor; Another part timer Timer is connected with arm processor, and the FLASH memory is connected with arm processor, and arm processor is connected with the RAM memory respectively at the A/D converter; A back part contains fault warning for double loop power supply, and three parts are connected on the bus board simultaneously.
Described CPLD processor connects the two-way light-coupled isolation simultaneously.
Module described in the utility model adopts two CPLC control technologys, uses two RS485 interfaces to monitor 3 typhoon machines simultaneously, and 1 fiber optic Ethernet cause for gossip now sends the whole running statuses and the fault message of cooling device to host computer, and blower fan is carried out speed governing.Port is supported various communications protocols such as MODBUS.
The utility model makes transformer cooling device control loop obtain significant improvement.Make control circuit moduleization, The whole control is simple, clear, reliable.Reduce the volume of original sub-control box, rotation speed of fan is controlled simultaneously, has adapted to the demand of current intelligent grid.
The utility model has reduced contactor, auxiliary relay and the time relay in original control loop etc. and has disperseed components and parts, and the volume of module of the present invention own is less again, makes the sub-control box smaller volume of transformer cooling device.Save cable, wiring is simple, is improved by property, can be according to conditions such as ambient temperature, temperature of oil in transformer, operating load, real time altering rotation speed of fan, not only saves energy, noise-decreasing, and can prolong transformer's life span, meet the intelligent grid demand for development.
