Technical field
The utility model relates to water-cooled transformer refrigeratory control field, refers to especially a kind of water-cooled transformer refrigeratory switch board.
Background technology
Water-cooled transformer is the major equipment of power transformation after electric system water-energy generating electricity, and its major function is after water-energy generating electricity, to change electric pressure, conveying AC energy.Due to structure and physical characteristics aspect, in transformer operational process, unavoidably can produce open circuit loss and load loss, and be converted into heat make transformer temperature raise.Too high temperature makes transformer ability to work and Efficiency Decreasing, acceleration insulation ag(e)ing, reduces serviceable life.This will dispel the heat to transformer, the processing of lowering the temperature.The electrical circuit that current water-cooled transformer refrigeratory control is built mainly with electromagnetic type hardware is as control, the shortcomings such as its such hardware-in-the-loop is loaded down with trivial details, complicated operation, reliability are low, high cost, maintenance is large, automaticity is extremely low.
Utility model content
The purpose of this utility model is to provide a kind of water-cooled transformer refrigeratory switch board, this switch board is using PLC controller as control device, man-machine interface is as visual windows and operation interface, gather pasta real time temperature by temperature collect module outputs to control oil pump motor and controls current motorized valve after PLC controller is processed, thereby accurately control the temperature of water-cooled transformer, realized the robotization control of water-cooled transformer refrigeratory.
To achieve these goals, the utility model has adopted following technical scheme: a kind of water-cooled transformer refrigeratory switch board, the PLC controller of comprise rack, being located at interior of equipment cabinet be located at man-machine interface on rack and that be connected with PLC controller, described PLC controller is connected with temperature collect module and control oil pump motor respectively, and described control oil pump motor is connected with current motorized valve.
Further, on described PLC controller, be connected with power module.
Further, on described PLC controller, be connected with Cooler Fault signal input module and switch board fault-signal output module.
Further, described PLC controller is provided with RS485 serial interface.
The beneficial effects of the utility model are: adopt after said structure, using PLC controller as control device, man-machine interface is as visual windows and operation interface, gather pasta real time temperature by temperature collect module, then be sent to PLC controller, after PLC controller is processed, output to control oil pump motor and control current motorized valve, control the instruction of current motorized valve executable operations, carry out cooling to transformer, thereby accurately control the temperature of water-cooled transformer, realized the robotization control of water-cooled transformer refrigeratory.
Man-machine interface is embedded on switch board, facilitates man-machine conversation, setup parameter and the duty of observing each parts, handled easily.
