Abstract
The utility model provides to a transformer oil level indicator which can transmit data remotely. The technical problem needs solving is that the oil level indicator arranged on the oil conservator of the transformer can indicate the oil surface position or the oil surface position or send out alarm signal. A consumer must go to the spot to observe the indication of the pointer of the oil level indicator if the consumer wants to know about the oil level of a device which is not only convenient but also has a visual error. The key point of the utility model is that the utility model includes a dial, a body, a transmission part and a floating ball. The stationary shaft of the alnico support saddle in an oil level fuel level gauge and the rotating shaft of an angle sensor or regulation resistance are coaxial. The output end of the angle sensor or regulation resistance connects the input end of a transmitter. The positive effect of the utility model is that the consumer can monitor the liquid level of the device visually and clearly. The utility model sets a maximum and minimum liquid level alarm. When the oil level exceeds the oil level range, the utility model sends out an alarm signal automatically to realize a remote oil level monitoring and alarm.
Description
Technical field
The utility model relates to a kind of transformer pointer type fuel level indicator, particularly has remote data transport functions transformer pointer type fuel level indicator.
Background technology
On the oil conservater of the large and medium-sized full-sealed transformer of oil immersed type, pointer type fuel level indicator is installed, promptly is installed in the scene, be used for showing the oil level of full-sealed transformer oil conservater.When oil level changes in the transformer oil conservater; oil level indicator can in time indicate the pasta position; when oil level in the oil conservater is below or above the red alert district of oil level setting value; oil level indicator can in time send alerting signal prompting transformer operation exception or cut off the electricity supply by automatic control system, makes transformer exempt from destruction.Pointer type fuel level indicator mainly is made up of dial plate, table body, running part, warning part, ball float etc.When in the oil conservater during oil level lifting, ball float swings up and down, and drives pointer by the running part in the oil level indicator and rotates, thereby the variation of oil level is shown on dial plate.Weak point is: the pointer that pointer type fuel level indicator only has an oil level shows and the switching value output function of the alerting signal of the peak of pasta, minimum point.To understand the oil level of equipment as the user, must watch both inconvenience, have the collimation error again, can not accurately reflect the actual oil level in the equipment to the on-the-spot indication that watch the oil level indicator pointer.
Summary of the invention
, the purpose of this utility model provides a kind of pointer transformer oil level meter of teletransmission oil level indication but being to overcome the deficiency of above-mentioned prior art.
The purpose of this utility model is achieved in that it has dial plate, table body, running part, ball float, it is characterized in that: the stationary shaft of the magnet steel bearing in the oil level gage and the rotating shaft coaxle of angular transducer or potentiometer, the input end of the output termination transmitter of angular transducer or potentiometer.When oil level changes, the upper and lower swing of ball float is by the transmission of oil level indicator internal mechanism, the magnet steel bearing rotating magnetic steel bearing and the axle thereof that drive in the oil level gage rotate the rotation of drive oil level gage pointer, the oil level of oil conservater is indicated by pointer on dial plate, angular transducer or potentiometer are rotated, angular transducer or resistance signal that is proportional to angle of potentiometer output, this signal is converted to 4mA～20mA industrial standard current signal by transmitter, be sent in the remote pulpit, simulation shows liquid level.
The utility model is compared with the prior art scheme, and the advantage that has is: the user can be directly perceived in the pulpit, the liquid level of clear monitoring equipment.The highest, minimum level that oil level is set are simultaneously reported to the police, and when oil level exceeds the oil level scope, send alerting signal automatically, realize remote oil level monitoring and warning.
Description of drawings
Further specify the utility model below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present utility model.
The A of Fig. 2 Fig. 1 is to view.
Fig. 3 is the synoptic diagram that the utility model connects the digital display controller table.
Fig. 4 the utility model connects the synoptic diagram of computer data acquisition system.
Embodiment
Referring to Fig. 1,2, it has dial plate 9, table body 2, running part 1, ball float 8, the stationary shaft 5 of the magnet steel bearing 7 in the oil level gage and the rotating shaft coaxle of angular transducer 6, the input end of the output termination transmitter 3 of angular transducer.When oil level changes, the upper and lower swing of ball float is by the transmission of oil level indicator internal mechanism, the magnet steel bearing rotating magnetic steel bearing and the axle thereof that drive in the oil level gage rotate the rotation of drive oil level gage pointer, the oil level of oil conservater is indicated by pointer 4 on dial plate 9, angular transducer is rotated, resistance signal that is proportional to angle of angular transducer output, this signal is converted to 4mA～20mA industrial standard current signal by transmitter, be sent in the remote pulpit, simulation shows liquid level.
Referring to Fig. 3, the 4mA of the output of transmitter～20mA industrial standard current signal can connect the digital display controller table 10 of built-in 24V direct current signal power supply, and the 11st, high low oil level alarm switch.
Referring to Fig. 4,, just insert computer data acquiring equipment after generally the current signal of output will being transformed to the voltage signal of 1～5V if the signal of oil level gage will be imported computer data acquiring and supervisory system or other self-actuated controllers (as PLC).
