Technical Field
The utility model relates to a power equipment technique especially relates to a transformer stores up oil tank oil level on-line monitoring device.
Background
The oil level monitoring result of the transformer oil conservator is an important basis for whether the transformer can safely operate. Most of the existing oil level meters for oil level monitoring are mechanical pointer type or oil level pipe type, the oil level is displayed on site according to the mechanical principle, and the oil level meters can only transmit high and low alarm signals to a background measurement and control screen and cannot monitor the change of the oil level in real time; and as most of the administered substations are unattended, power operation and maintenance personnel are required to copy and report the oil level of the main transformer from each substation to each month, and the data statistics work of the oil level of the oil storage cabinet is completed.
The above monitoring and statistical modes mainly consist of the following drawbacks:
(1) if the mechanical oil level gauge fails, the real oil level cannot be checked, and the oil level gauge cannot be found timely after the failure, so that the safe operation of the transformer is influenced;
(2) if a floating ball of an oil level meter in the oil storage cabinet is blocked or a capsule is blocked, the real oil level cannot be reflected, and a false oil level is easy to appear;
(3) operation and maintenance personnel must report the oil level of hundreds of main transformer oil storage tanks of fifty or more transformer substations in the jurisdiction at the end of each month, the cost of manpower and material resources is high, and the change of the oil level cannot be monitored in real time.
SUMMERY OF THE UTILITY MODEL

For realizing the above-mentioned purpose, the utility model provides a transformer stores up oil tank oil level on-line monitoring device, including the host computer, the host computer links to each other with at least one module that gathers, the module that gathers links to each other with at least one collection module, collection module is including setting up in the oil level sensor and the liquid level display appearance that store up the oil tank bottom, oil level sensor warp the liquid level display appearance with the module that gathers links to each other, the host computer the module that gathers collection module all links to each other with power module.
Preferably, the liquid level display instrument comprises a display screen and an AD converter, and the oil level sensor is connected with the display screen through the AD converter.
Preferably, the summarizing module is connected with the eight paths of collecting modules through an I/O interface, and the summarizing module is an E-CPU/A14QE processor.
Preferably, the host computer includes industrial computer, converter and display, the industrial computer is through RS485 communication cable and six the converter links to each other, the converter through RS232 communication cable with the display links to each other.
Preferably, the collecting module is communicated with the industrial personal computer through an RS485 communication cable.
Therefore, the utility model discloses an adopt the transformer of above-mentioned structure to store up oil tank oil level on-line monitoring device can be in real time with the oil level data transmission of gathering to the host computer to show in real time, improved data reading efficiency and degree of accuracy, saved the cost of labor.
